Answer:
45.82 square inches
Step-by-step explanation:
Use the formula for the surface area of a sphere, A = 4[tex]\pi[/tex]r²
If the diameter is 3.82 inches, the radius is 1.91 inches.
Plug in 3.14 as [tex]\pi[/tex] and 1.91 as r, and solve:
A = 4[tex]\pi[/tex]r²
A = 4(3.14)(1.91²)
A = 45.82
So, approximately 45.82 square inches of material are needed.
Tenemos 2 garrafas una al 20% y otra al 30%. Cual es su capacidad de las garrafas si tenemos 12 litros de agua
Answer:
Cada garrafa tiene una capacidad de 24 litros.
Step-by-step explanation:
Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.
Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:
(20%/100%)*V
Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:
(30%/100%)*V
El volumen total de agua es la suma de esos dos volúmenes, que nos da:
(20%/100%)*V + (30%/100%)*V
Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:
12 L = (20%/100%)*V + (30%/100%)*V
Ahora podemos resolver esto para V.
12L = 0.2*V + 0.3*V
12L = 0.5*V
12L/0.5 = V
24L = V
Cada garrafa tiene una capacidad de 24 litros.
5w - w/x when w=6 and x =2
Answer:
27
Step-by-step explanation:
w = 6
x = 2
5w
= 5 x 6
= 30
w / x
= 6 / 2
= 3
5w - w / x
= 30 - 3
= 27

Step-by-step explanation:
Solve for x. Enter your answer below as an improper fraction in lowest terms,
using the slash (7) as the fraction bar.
X- 2 1/4 = 1/18
Answer:
x = [tex]\frac{83}{36}[/tex]
Step-by-step explanation:
Given
x - 2 [tex]\frac{1}{4}[/tex] = [tex]\frac{1}{18}[/tex] ( change mixed number to improper fraction )
x - [tex]\frac{9}{4}[/tex] = [tex]\frac{1}{18}[/tex]
Multiply through by 36 ( the LCM of 4 and 18 ) to clear the fractions
36x - 81 = 2 ( add 81 to both sides )
36x = 83 ( divide both sides by 36 )
x = [tex]\frac{83}{36}[/tex]

Mom buys a phone on hire purchase.First she pays a deposit of $100,followed by 12 monthly installments of $80 each How much money does mom pay for the phone?
N.B.Calculation needed or Working out
Answer:
She pays $1060 for the phone.
Step-by-step explanation:
Deposit = $100
She pays $80 each month for a year. $80 x 12 = $960. Then we need to add the deposit with the monthly instalments to find the total. $100 + $960 = $1060
Total:
$1060
A spinner has six sections: two sections are labeled a comma two sections are labeled B, and two sections are labeled see?
a. what is the sample space for the spinner?
b. what is the probability of spinning and landing on it?
Answer:
Step-by-step explanation:
a. The sample space for this spinner would be A, B or C . Since these are the only possible outcomes in this specific spinner.
b. The spinner has a total of 6 sections but each letter has 2 sections dedicated to it. Therefore, this makes only 3 possible outcomes in which the spinner will only land on 1. This means that the probability of each letter would be 1/3

Make x the subject of the formula.
[tex]r + \sqrt{x} = 9[/tex]
Hi there! Given the equation below.
[tex] \large{r + \sqrt{x} = 9}[/tex]
First is to subtract both sides by r-term to isolate x-term.
[tex] \large{r + \sqrt{x} - r = 9 - r} \\ \large{ \sqrt{x} = 9 - r}[/tex]
Because the x-term is in square root form. We have to square both sides to get rid of the square root.
[tex] \large{( \sqrt{x})^{2} = {(9 - r)}^{2} } \\ \large{x = {(9 - r)}^{2} }[/tex]
Alternative Solution
[tex] \large{x = {r}^{2} - 18r + 81}[/tex]
Answer
x = (9-r)² x = r²-18r+81Both answers work. Any questions about this can be asked through comment.
Which of the following expressions are equivalent?
1. 5(a + 3)
2. 5a + 15
3. 3(2a + 5)
Answer:
1 and 2 are equivalent
For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

A rectangle has an area of 75.2m2.
One of the sides is 0.8m in length.
Work out the perimeter of the rectangle.
Answer:
189.6m
Step-by-step explanation:
Area of reactangle= side₁ ×side₂
Let the other side of the rectangle be x meters.
Area of rectangle= 75.2m²
0.8x= 75.2
x= 75.2 ÷0.8
x= 94
Perimeter of rectangle
= 2(side₁ +side₂)
= 2(0.8 +94)
= 189.6 m
Could anyone offer a step by step on how to solve this problem?
Answer:
[tex]m\angle 1 = 40^\circ[/tex]
Step-by-step explanation:
First, notice that the two lines are parallel as indicated by the arrow.
Therefore, by the Alternate Interior Angles Theorem:
[tex]\angle 1\cong \angle 2[/tex]
So:
[tex]m\angle 1 = m\angle 2[/tex]
Substitute:
[tex](2x+20)=(3x+10)[/tex]
Solve for x. Subtract 2x from both sides:
[tex]20=x+10[/tex]
And subtract 10 from both sides:
[tex]x=10[/tex]
We know that:
[tex]m\angle 1 = 2x+20[/tex]
Substitute. Hence:
[tex]m\angle 1 =2(10)+20=40^\circ[/tex]
In triangle HIJ, N is the centroid. If HK = 10, find KI.
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.
Johanna buys two poster frames that have the same area, but different shapes. One is a rectangular frame with a width of 40 inches and a length of 30 inches. The other frame is square. What a poster with dimensions of 36 inches X 36 inches fit in the square frame?
Answer:
No, the poster would not fit in the frame
Step-by-step explanation:
A rectangle is a quadrilateral (has 4 sides and 4 angles) with two pair of opposite and equal sides.
A square is a quadrilateral in which all sides are equal.
Given that the rectangular frame has a width of 40 inches and a length of 30 inches. The area of the rectangular frame is:
Area of rectangular frame = length * breadth = 40 inches * 30 inches = 1200 in²
Since the square frame has the same area as the rectangular frame, hence:
Area of square frame = length * length
length² = 1200
length = √1200 = 34.64
Therefore the dimensions of the square frame is 34.64 inches by 34.64 inches.
Hence a poster with dimensions of 36 inches X 36 inches cannot fit in the square frame.

12x+24x +18 = 36x +24 -6
Combining like terms
36x+18 = 36x +18
Subtracting 36x from each side
18 = 18
This is always true so it does not matter what x is, the left had side will equal the right hand side

Sonja wants to find the mass of her parakeet. What unit would be best to measure the bird’s mass?
Answer:
Died speciman prior would be best to measure the bird’s mass.The length (also bill-to-tail length) of a bird is usually measured from dead specimens prior to their being skinned for preservation. The measurement is made by laying the bird on its back and flattening out the head and neck gently and measuring between the tip of the bill and the tip of the tail.

Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a diameter of 4.4 centimeters.
The volume of the sphere is about
cm^3 just
Answer:
Volume of sphere = 44.57 cm³
Step-by-step explanation:
Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]
Volume of sphere = [1.333][3.14][10.648]
Volume of sphere = 44.568
Volume of sphere = 44.57 cm³
A chair rental company charges $100 for delivery plus $3 per chair.
Write an explicit function for the total cost, T(c), of renting c number of
chairs.
Answer:
T(c) = 100 + 3*c
Step-by-step explanation:
cost = fee + cost per chair * number of chairs
T(c) = 100 + 3*c
Answer:
T ( c)= $ 100 + $ 3 c
Step-by-step explanation:
Given that :-
Fee for delivery = $ 100Cost per chair = $ 3No. of chair = cTo Find :-
Total cost T( c) of renting c no. of chairs.Solution :-
Total Cost, T ( c) = Fee + cost per chair × no. of chairs.
T ( c) = $ 100 + $ 3 × c
T ( c) = $ 100 + $ 3 c
