A solid cubiod measures 7cm, 5cm,3cm. (a) Calculate the total surface area of the cubiod. (b) A cube has the same volume as the cubiod. Calculate the length of an edge of this cube
Answer:
Te total surface area (TSA) of the cuboid is the sum of the area of its 6 faces
if the cuboid has width(w)=7 cm, Height (h)=3cm., length(h)=5cm
A=lw=5*7=35 cm²
A2=hw=3*7=21
A3=lh=5*3=15
TSA=2(lw+hw+lh)
TSA=2(35+21+15)
TSA=2(71)=142cm²
volume of the cubiod=l*w*h
V=lhw
V=7*5*3= 105 cm³
the length of an edge of this cube:
since it is a cube then all sides are equal l=w=h

What is the distance between 7.65 and -4.18 on a number line
Answer:
11.83
Step-by-step explanation:
11.83 because you would add them to find distance and 7.65+4.18=11.83
The required distance on the number line between the points -4.18 and 7.65 is 11.83
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Given that, the distance between 7.65 and -4.18 on a number line
On the number line, -4.18 lies on the left of the zero, and 7.65 lies on the right, so the required distance would be the addition of the two points. So,
Distance = 7.65 - (-4.18)
Distance = 7.65+4.18
Distance = 11.83
Thus, the required distance on the number line between the points -1.85 and 7.36 is 9.21.

Rental of space = $68 per guest; Downpayment = 25% of total cost; Payment due one month before the reception includes a 7.4% interest payment on the balance.
This question is incomplete, the complete question is;
PROBLEM SOLVING WITH PERCENTS: You are planning a wedding reception for 75 guests that will take place in exactly 10 months. There are two different sites that you are contemplating using, with the stipulations on payments as described below. Determine the TOTAL cost of renting each location.
Rental of space = $68 per guest; Down payment = 25% of total cost; Payment due one month before the reception includes a 7.4% interest payment on the balance.
Answer: Total Cost of Renting = $5312.29
Step-by-step explanation:
Given that;
Rental space = $68 per guest, down payment = 25%, 7.4% interest payment on the balance.
Total Cost of Renting = Down Payment + Remaining payment
Total Cost of Renting = $68 × Guests × 25% + ($68 × Guest - Down payment) × (1 + Interest *9/12)
Total Cost of Renting = $68 × 75 × 25% + ($68 × 75 - Down payment) × (1 + 7.40% × 9/12)
Total Cost of Renting = $1275 + ($5100 - 1273) × (1.0555)
Total Cost of Renting = $1275 + 4037.29
Total Cost of Renting = $5312.29
Which of the following is most likely the next step in the series?
Answer:
Option (c)
Step-by-step explanation:
From the diagram attached,
First circle has 4 points on its circumference. By joining these points we get a quadrilateral inside the circle.
Second circle has 3 on its circumference. By joining these points we get a triangle inscribed in the circle.
In 3rd circle points on the circumference have been reduced again to 2. By joining these points we get a straight line.
Following the same pattern in the 4th circle we will get a single point on the circumference of the circle.
Therefore, Option (c) will be the answer.

We can subtract both sides of the equation by 3, getting 3 + p - 3 = 8 - 3.
Then we can evaluate, getting p = 8 - 3 = 5.
Answer: 5
Ok, this is just simple math problems think of it like this....
3+p=8 ➡ rearrange the equation
p= 8 - 3 ➡ this is because p has to be added to 3 to make 8
p= 5

Please help me answer this question! It’s in the picture!
Step-by-step explanation:
We can prove this by using similar triangles. We know that angle ABE and ACD are SIMILAR(we know that by the sign in between them).Therefore, we also know that CDA and BEA are similar, and EAB and DAC are similar. Since all the angles are similar, we also know that the side lengths are equal in proportion. AB/AE is equal to AC/AD. When assigned values, that would create a proportion that is equal since the smaller triangle is similar to the bigger one. If you want to create a proof, break each statement into its own section.

A sampling frame a. is a list of population elements from which the sample will be drawn. b. is the list of population elements actually included in the sample. c. usually provides biased statistics. d. is a form of probability sampling.
Answer:
A. is a list of population elements from which the sample will be drawnStep-by-step explanation:
Sampling frame is the list of people or items from which a sample is taken.
Sampling is used because it is almost impossible to study entire population. Sampling allows us to find information about a population on the basis of results from a subset of the population, without studying every individual. It is easier and cost effective process.
A sampling frame refers to A. a list of population elements from which the sample will be drawn.
Sampling frame simply means the actual set of units from where the sample will be drawn.A sampling frame consists of all the items that are in the population. Therefore, a sampling frame is a list of population elements from which the sample will be drawn.Read related link on:

How 17 | 12. The Mad hatter is stocking up on tea for his
unbirthday parties. The market sells 5 boxes of tea
for $66 At this rate, how many boxes of tea can he
buy with $30?
Answer:
About 2.3 boxes of tea
Step-by-step explanation:
If we divide the price by the number of boxes, in this case, 66 / 5 we would get 13.2. So the means that each box would cost $13.20. So if we divide 30 by the cost of each box we would get approximately 2.3 boxes of tea. Hope this helps :)
The following are the means and standard deviations of some well-known standardized tests, referred to as Test A, Test B, and Test C. All three yield normal distributions.
Test Mean Standard deviation
Test A 500 100
Test B 150 8
Test C 70 15
Required:
a. A score of 450 on Test A corresponds to what score on Test B?
b. A score of 625 on Test A corresponds to what score on Test C?
Answer:
(a) A score of 450 on Test A corresponds to a score of 146 on Test B.
(b) A score of 625 on Test A corresponds to a score of 88.75 on Test C.
Step-by-step explanation:
We are given the means and standard deviations of some well-known standardized tests referred to as Test A, Test B, and Test C. All three yield normal distributions.
Test Mean Standard deviation
Test A 500 100
Test B 150 8
Test C 70 15
So, [tex]\mu_A[/tex] = 500 and [tex]\sigma_A[/tex] = 100
[tex]\mu_B[/tex] = 150 and [tex]\sigma_B[/tex] = 8
[tex]\mu_C[/tex] = 70 and [tex]\sigma_C[/tex] = 15
(a) We have to find a score of 450 on Test A corresponds to what score on Test B.
For this, firstly we will find the z-score for a score on Test A and then equate with that of Test B.
z-score of 450 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]
= [tex]\frac{450-500}{100}[/tex] = -0.5
So, this z-score corresponds to the score on test B, i.e;
z-score on test B = [tex]\frac{X_B-\mu_B}{\sigma_B}[/tex]
-0.5 = [tex]\frac{X_B-150}{8}[/tex]
[tex]X_B= 150-(0.5 \times 8)[/tex]
= 150 - 4 = 146
Hence, a score of 450 on Test A corresponds to a score of 146 on Test B.
(b) We have to find a score of 625 on Test A corresponds to what score on Test C.
For this, firstly we will find the z-score for a score on Test A and then equate with that of Test C.
z-score of 625 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]
= [tex]\frac{625-500}{100}[/tex] = 1.25
So, this z-score corresponds to the score on test C, i.e;
z-score on test C = [tex]\frac{X_C-\mu_C}{\sigma_C}[/tex]
1.25 = [tex]\frac{X_C-70}{15}[/tex]
[tex]X_C= 70+(1.25 \times 15)[/tex]
= 70 + 18.75 = 88.75
Hence, a score of 625 on Test A corresponds to a score of 88.75 on Test C.

The area of the top face of a cube is 9 square centimerers. Use 9 of these cubes to make a rectangular prism. What is the volome of the rectangular prism?
Answer:
243 cm³
Step-by-step explanation:
A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that
Length x width = 9 square centimeters
But, since length and width are the same, we have that they are equal to [tex]\sqrt{9} =3[/tex] cms (since 3² = 9).
Thus, the volume of each cube is 3³ = 27 cm³
We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.
Volume of prism = 9 (27) = 243 cm³
Answer:
243 cm³

Audrey sells closet organization systems. She is paid a commission of 5.14% of her first $1500.00 in sales during the week and 10% on all sales over $1500.00. What is her commission in a week during which she sells $7500.00 worth of closet organization systems?
Answer:
$827.1Step-by-step explanation:
We proceed to calculate the 5.14% of the $1500 in sales during the week
Hence she is paid 1500*(5.14/100)
= 1500*0.0514
= $77.1
And also she is paid 10% of sales over $1500 and she made sales of $7500
her commission is
= (10/100)*7500
=0.1*7500
= $750
Hence in all for the week her commission will be (if she sells $7500)
= 77.1+750
= $827.1
Define a variable, write an equation, and solve the problem. Adults' tickets to a play cost $5 and students' tickets
cost $2. If 295 tickets were sold and a total of $950 was collected, how many students' tickets were sold?
Answer:
175
Step-by-step explanation:
Let A be the number of adult tickets and S be the student's tickets
{A + S = 295 or S = 295 - A
{5A + 2S = 950
5A + 2(295 - A) = 950
5A + 590 - 2A = 950
3A = 360
A = 120
S = 295 - 120 = 175

Write an algebraic expression that models the word phrase.
The product of 8 and the sum of a number x and 14
Answer:
8(x + 14)
Step-by-step explanation:
The term product signifies multiplication in mathematics. However, in order to find a product, we must have two or more terms to multiply. Because we are finding the product of 8 and the sum of a number x and 14, we will place the sum in parentheses to show they are being added together.
Using this knowledge, we are left with the sum in parentheses (x + 14) and the number 8 to multiply it.
To simplify, this can be written as 8(x + 14).
Breanna has $150 and she needs to save at least $560 for spring break trip if she can save $45 per week how long will it take her to save enough money let W equals weeks saving money right and in quality to
Answer: It will take her more than 9 weeks.
Step-by-step explanation:
If she already has $150 that will be constant and if she can save $45 per week the we will have the expression 45w where w is the number of weeks.
Together it will be 150 + 45w
Now the money has to be at least $560 so it will be
150 + 45w ≥ 560 Now solve for w
-150 -150
45w ≥ 410
w ≥ 9.1
