Find the surface area and volume of the prisim it has 5cm 12cm 13cm and 28cm The surface area of the prism is (blank)cm2 The volume of the prism is (blank)cm3 pls help i need this quick!
Answer:
A = 1124 cm²
V = 840 cm³
Step-by-step explanation:
Assuming the prism is a triangular prism,
Applying,
V = 1/2bhL.................. Equation 1
Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle
From the question,
Given: L = 28 cm, 12 cm, h = 5 cm
Substitute these values into equation 1
V = (5×12×28)/2
V = 840 cm³
Surface area (A) = bh+(a+b+c)L
A = (5×12)+(13+13+12)28
A = 60+1064
A = 1124 cm²
A right rectangular prism has a base with an area of `25\ \frac{1}{2}`square feet and a volume of 153 cubic feet. What is the height, in feet, of the right rectangular prism?
Answer:
Height = 6 feet
Step-by-step explanation:
Given the following data;
Base area = 25½ ft²
Volume = 153 ft³
To find the height of the right rectangular prism;
Mathematically, the volume of a right rectangular prism is given by the formula;
Volume = base area * height
Substituting into the formula, we have;
153 = 25½ * height
153 = 51/2 * height
Cross-multiplying, we have;
306 = 51 * height
Height = 306/51
Height = 6 feet
Right rectangular prism is also called cuboid. The height of the right rectangular prism considered is evaluated as of 6 ft
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
For this case, we're provided that:
Base area of the right rectangular prism = [tex]25\dfrac{1}{2} = 25 + 0.5 = 25.5 \: \rm ft^2[/tex]Volume of the right rectangular prism = [tex]153\: \rm ft^3[/tex]Let the length and width of the prism be L ft and W ft
Let the heigth of the prism be H ft
Then, we get:
Area of base = [tex]L \times W = 25.5 \: \rm ft^2[/tex] (since base is a rectangle with length L and width W).Volume of prism = [tex]V = H \times L \times W = H \times 25.5 = 153 \: \rm ft^3[/tex]Thus, we get:
[tex]H \times 25.5= 153\\\\\text{Dividing both the sides by 25.5}\\\\H = \dfrac{153}{25.5} = 6 \: \rm ft[/tex]
Thus, the height of the right rectangular prism considered is evaluated as of 6 ft.

The most likely answer would be 282,240.
Step-by-step explanation:
I got a different value than the choices you've given me. But if 282,240; 14; and 21 are your only options, then the most likely answer would be 282,240. Any number followed by an exclamation point means that it will be multiplied by all whole numbers from 1 to that number. For example, 4! would be 1 * 2 * 3 * 4 = 24.

Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone calls
Step-by-step explanation:
Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
From the above question:
4 minutes = 2 phone calls
16 minutes = x
Cross Multiply
4 minutes × x = 16 minutes × 2 phone calls
x = 16 minutes × 2 phone calls/4 minutes
x = 8 phone calls
Therefore,
Eduardo has to route 8 phone calls to spend a total of 16 minutes on the phone

A rectangle is placed around a semicircle as shown below. The length of the rectangle is 14 m . Find the area of the shaded region. Use the value 3.14 for , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
21.07 m²
Step-by-step explanation:
Please find the complete question in the attached image
Area of shaded region = area of rectangle - area of semicircle
Area of semicircle = [tex]\frac{1}{2}[/tex]πr²
π = 3.14
r = radius = 14/2 = 7m
the diameter of the semicircle is 14m , thus the radius would be half of the diameter
(1/2) x 3.14 x 7² = 76.93 m^
Area of a rectangle = length x width
width = radius of semicircle = 7
14 x 7 = 98 m²
Area of shaded region = 98 m² - 76.93 m^ = 21.07 m²
The ratio of cattle to horses on the ranch was 12 to 3. The combined number of cattle and horses was 960. How many horses are on the ranch?
Answer: There are 192 horses in the ranch

Copyright
Answer: p=25%
Step-by-step explanation:We have a sample of 100 clients.
To find the probability that a randomly selected customer chooses a cold drink, we must first count how many people in the sample chose cold drinks.
The table shows that cold drinks were
8 small, 12 medium and 5 large.
Then the number of cold drinks was:
The probability that the customer ordered a small given that he or she ordered a hot drink is 67%.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given a table which shows the number of orders of coffee by first 100 customers.
Out of it,
Total number of orders which are hot = 5 + 48 + 22 = 75
Number of orders which are small out of the total hot drinks = 5
Probability = 5/75 = 0.6667 = 66.67% ≈ 67%
Hence the required percent is 67%.

write additive and multiplicative inverse of19/-6 and-2/3
Additive inverse of 19/-6 is 19/6
Additive inverse of -2/3 is 2/3
Multiplicative inverse of 19/-6 is -6/19
Multiplicative inverse of -2/3 is 3/-2 (also written as -3/2)
Step-by-step explanation:
(a) The additive inverse of a number is that number that when added to it gives 0.
For example, the additive inverse of x is -x.
This is because adding -x to x gives 0. i.e
x + (-x) = 0
In other words, the additive inverse of a number is the negative of that number.
Given:
(i) 19/-6
The additive inverse of 19/-6 is the negative of 19/-6 which is -(19/-6).
-(19/-6) then gives 19/6
Therefore, the additive inverse of 19/-6 is 19/6
(ii) -2/3
The additive inverse of -2/3 is the negative of -2/3 which is -(-2/3).
-(-2/3) then gives 2/3
Therefore, the additive inverse of -2/3 is 2/3
(b) The multiplicative inverse of a number is that number that when multiplied by it gives 1.
For example, the multiplicative inverse of y is 1/y.
This is because multiplying y by 1/y gives 1. i.e
y x (1/y) = 1
In other words, the multiplicative inverse of a number is the reciprocal of that number.
Given:
(i) 19/-6
The multiplicative inverse of 19/-6 is the reciprocal of 19/-6 which is 1/(19/-6).
1 / (19/-6) then gives -6/19
This is found by just swapping the numerator(19) and the denominator(-6)
Therefore, the multiplicative inverse of 19/-6 is -6/19
(ii) -2/3
The multiplicative inverse of -2/3 is the reciprocal of -2/3 which is 1/(-2/3).
1 / ( -2/3) then gives 3/-2
This is found by just swapping the numerator(-2) and the denominator(3)
Therefore, the multiplicative inverse of -2/3 is 3/-2 (also written as -3/2).

9514 1404 393
Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3

Answer:
0.50
Step-by-step explanation:
The question states at least 2 which means 2 or more.
The only applicable numbers to look at would be 2 and 3.
First of all we find 2 since it's missing.
Now all probability distributions must add up to 1.
As we can see there are 0.20, 0.30 and 0.40 which is equal to 0.90. Therefore 1 - 0.90 = 0.10 which would be 2.
Hence, the peobability that x is at least 2 is 0.10 + 0.40 = 0.50.
