Answer:

$39.50

Step-by-step explanation:

Multiply 7.9 by 5 to get 39.5

Answer:

if 10 of them costs $7.90 then 50 would cost $39.50.

there are two different ways of doing this:

1. you could divide $7.90 by 10 which would get you $0.79 (the price of one frozen juice bar) then multiply $0.79 by 50 to get $39.50 (the price of 50 frozen juice bars)

or

2. you could just take $7.90 and multipy it by 5 (b/c 10 x 5 is 50)

The original dimensions of the cardboard sheet are 12 inches by 12 inches, which is calculated by setting up an equation using the provided volume of the open-top box and the size of the squares cut from each corner.

Explanation:

Solving for the Original Dimensions of the Cardboard Sheet

To solve this problem, we need to find the original dimensions of the square sheet of cardboard that will create an open-top box with a volume of 128 cubic inches after 2-inch squares are cut from each corner and the sides are folded up. Since the volume of the box (V) is given by the formula V = length x width x height, we first denote the original side length of the cardboard as x inches. After cutting out 2-inch squares from each corner, we will fold up the sides, which means the new length and width of the box will be (x - 4) inches (since we lose 2 inches on each side). The height of the box will be 2 inches, which is the size of the square cut out from each corner. Therefore, the volume of the box can be expressed as 2(x - 4)^2.

To find the value of x, we solve the equation 2(x - 4)^2 = 128. Simplifying, we get (x - 4)^2 = 64. Taking the square root of both sides, we have x - 4 = 8. Adding 4 to both sides gives us x = 12. So, the original dimension of the cardboard is 12 inches by 12 inches.

Step-by-step explanation:

∠ FDG = ∠ CDB = 50° ( vertical angles are congruent ), thus

∠EDG = 90° - ∠ FDG = 90° - 50° = 40° → B

Answer:

65

Step-by-step explanation:

Part one is always the ones 'in these: ( )'. 12/3=4 4*2=8. So now it is 8^2+8-7. 8^2 is 8*8=64. 64+8-7=64+1=65

Start by working inside the parentheses which are these things ( )

The things inside the ( ) is "12 divided by 3 times 2"

Division comes first so 12 divided by 3 = 4.

4 times 2 = 8

So now we have 8^2 + 8 - 7

In PEMDAS, Exponents come before addition and subtraction, so 8^2 is 64.

64 + 8 = 72

Lastly is subtraction

72 - 7 = 65

65 is your answer.

The solution set can be given as:

[tex]\{x|x\ \epsilon\ R,x\neq -3\}[/tex]

Step-by-step explanation:

Given function:

[tex]f(x)=\frac{1}{2x+6}[/tex]

To find the domain of the function in set notation.

Solution:

For the function [tex]f(x)[/tex] to exist the denominator must be ≠ 0

We have the denominator [tex](2x+6)[/tex] which  cannot be = 0.

Thus, we can find the domain of the function using the above relation.

The function [tex]f(x)[/tex] will not exist when:

[tex]2x+6=0[/tex]

Solving for [tex]x[/tex]

Subtracting both sides by 6.

[tex]2x+6-6=0-6[/tex]

[tex]2x=-6[/tex]

Dividing both sides by 2.

[tex]\frac{2x}{2}=\frac{-6}{2}[/tex]

∴ [tex]x=-3[/tex]

Thus, the function will not exist at [tex]x=-3[/tex]. This means it has all real number solutions except -3.

The solution set can be given as:

[tex]\{x|x\ \epsilon\ R,x\neq -3\}[/tex]

The drama club receives $7 for each ticket that they sell.

Step-by-step explanation:

Given,

Amount received by school = x dollars

Amount received by school for 96 tickets = 96x

Amount received by drama club = remaining amount after school

Total amount of 96 tickets = 96x+672

Here,

96x is the share of school

672 is the share of drama club for 96 tickets.

Therefore;

96 tickets = dollars

1 ticket = [tex]\frac{672}{96}[/tex]

1 ticket = 7 dollars

The drama club receives $7 for each ticket that they sell.

To find the total amount of water needed to water all the plants in the house, the amount of water for a part of the plants is used to set up a proportion. After cross-multiplying and calculating, it is determined that 10/3 liters or approximately 3.33 liters of water is required.

If 4/3 liters of water is enough for 2/5 of the plants, then the amount of water required for all the plants can be found by setting up a proportion. We use cross-multiplication to solve for the unknown amount of water needed to water all the plants.

First, we express the given information as a fraction:

(4/3) liters

(2/5) plants

Next, we solve for the total water required (let's call it x):

(4/3) / (2/5) = x / 1

We cross-multiply to solve for x:

4/3 * 1 = x * (2/5)

Multiplying both sides by the reciprocal of (2/5), which is (5/2), to isolate x, we get:

(4/3) * (5/2) = x

Now we calculate:

x = (4 * 5) / (3 * 2) = 20/6 = 10/3 liters

Therefore, 10/3 liters of water, or approximately 3.33 liters, is necessary to water all the plants in the house.

Answer:

(h+8)+5

Step-by-step explanation:

First, you need to add 8 to h, which is h+8 and then you need to add 5 to the result, which means you need to put parentheses around h+8 because you need to do that first. then your answer becomes (h+8)+5.

After adding 8 to h and then 5 to the result, the final value will be h + 13.

To perform the specified operations, you first need to add 8 to the value of h and then add 5 to the result. This can be expressed as a mathematical expression:

Result = (h + 8) + 5

Start with the value of h.

Add 8 to it, which gives you (h + 8).

Now, take the result from step 2 and add 5 to it, yielding the final result.

This process essentially means you're increasing the original value of h by 8, and then further increasing the updated value by 5. The final result will be h + 8 + 5, or simply h + 13.

So, the answer is that you will end up with a value equal to h + 13 after performing these operations.

x = 45/7

Step-by-step explanation:

Write as an algebraic equation.

Look at each part in the word question : 0.7 of what number is 4 1/2

"0.7 of what number" can be written as 0.7x

The word "is" means equals.

0.7x = 4 1/2     <= The equation, using 'x' to represent the number.

To find the number, isolate 'x'.

0.7x = [tex]4\frac{1}{2}[/tex]    Convert mixed fraction to improper fraction

0.7x = [tex]\frac{(4*2)+1}{2}[/tex]     Multiply the whole number by the denominator and add it to the numerator

0.7x = [tex]\frac{9}{2}[/tex]     Now isolate 'x'

0.7x/0.7 = [tex]\frac{9}{2}/0.7[/tex]     Divide both sides by 0.7

x = [tex]\frac{9}{2}/0.7[/tex]     Simplify right side

x = [tex]\frac{9}{2}/\frac{7}{10}[/tex]     Rewrite 0.7 as a fraction

x = [tex]\frac{9}{2}*\frac{10}{7}[/tex]     To divide, you multiply a flipped fraction

x = [tex]\frac{9*10}{2*7}[/tex]     Multiply across the top and across the bottom

The volume of white color used by Maria is 20 liter

Solution:

Maria, a color specialist, mixes 2 parts of white and 13 parts of red to develop a particular shade

She creates 150 liters of the shade

Given ratio is:

2 parts of white and 13 parts of red

white : red = 2 : 13

Let the white mixed be 2x

Let the red mixed be 13x

Total shade = 150 liters

Therefore,

2x + 13x = 150

15x = 150

x = 10

Therefore, volume of white color used = 2x = 2(10) = 20

Thus, volume of white color used by Maria is 20 liter

Final answer:

A photocopy is not a dilation; dilations change size while maintaining shape, while photocopies replicate the original image at the same scale.

Explanation:

When you make a photocopy of an image, it is not considered a dilation. A dilation involves resizing an image while maintaining its shape, whereas a photocopy reproduces the original image at the same scale.

A dilation in physics refers to a transformation that changes the size of an object, typically without altering its shape. Examples of dilations can be seen in various optical processes such as lens systems and camera projections.

Photocopying is a replication process that duplicates an image onto another surface with the same proportions and characteristics as the original, making it distinct from a dilation.
