Solution

First, let's translate the problem into an equation:

y = 5x + 45.The number 5 represents 5 dollars per hour (slope), and 45 represents the y-intercept

The y-intercept is sometimes known as the initial value or initial cost in a problem. Since our y-intercept is 45, the initial value is $45.

to find the area of a hexagon you would use the formula (n-2)•180 and the (n) would be 6 because a hexagon has 6 sides so (6-2)= 4 and then 4•180 is 720. 720 is the area and you can do this with any polygon i believe

Answers

1) Correct option is C)

A fair coin is tossed 100 times and the head occurs 58 times and tail 42 times.

The experimental probability of getting a head is :

P(E)=

Total outcomes divided  by Number of head

58/100 = 29/50 (29/50x100) = 58% (C)

2) 19%​

Answer:

1. 42%

2. 33%

Step-by-step explanation:

1. Relative frequency = Number of successful trials ÷ Total number of trials

plug the numbers in and we get 42/100. 42/100 = 0.42 = 42%

2. Experimental probability = Number of in which the outcome occurs ÷ Total number of trials

plug the numbers in and we get 2/6 = 1/3 = 33%

Answer: A=9

Step-by-step explanation:

The equation for this table is x+16 =Y.

To solve for Y, we must plug in. (in other words, substitute the letters with (known) numbers).

A is in the 3rd row under the Y column. Hence, we will use the X value found in the same row, which is 3.

Hey need some help, I don't really under stand, I see that every one of them can be divided by 8 though. Thanks for the help!

Answers

Answer:

the answer should be 1:8 or 1/8 either way it tells you in the scale factor and in the fraction so remember we need to divide first the sculpture then the model since the sculpture has highest numbers and then the mode so as shown below here are the results of each one.

56/7=8

40/5=8

72/9=8

so the scale factor should be 1:8 since 8 units is 8 units in real life since and the fraction should be 1/8 so hopefully those are the correct answer and tell me if i am wrong so i can correct the answer to make it better.

(D) 500%

Answers

The percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.

What is the percentage?

The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.

It is given in the question that the number of students in the marching band increased from 100 to 125 so we need to find the percentage increase of the students.

The percentage increase of the students will be calculated as:-

% increase=[(125-100)÷(100)]x100

% increase=[(25)÷(100)]x100

% increase= [0.25x100]

% increase= 25%

Hence the percentage of the increase will be 25% when the number of students in the marching band increased from 100 to 125.

Answers

Total mass of box = 4 kg or 4000 grams

Number of oranges= 4000/80

= 50 oranges

Answer:

50 oranges are in the box

Step-by-step explanation:

First, find the converting of 1 kg to grams (1kg = 1000g)

Then, convert how many kg is the box of oranges (4kg = 4000g)

Finally, divide the total grams of the box by the total grams per EACH orange in the box (4000g ÷ 80g = 50)

Therefore, there are 50 oranges in the box

(b) Determine the scale factor for dilating circle Q so that it has the same radius as circle P.

P radius 20, Q radius 2, radiusQ*10 = radiusP, so the scale factor is 10

(c) Are circles P and Q similar? Explain your answer.

A storage box has a base area of 314.5 square inches and a height of 8.5 inches.

What is the volume of 5 of these boxes?

Enter your answer as a decimal in the box.

Answers

Volume is base x height, and since you have 5 boxes, it’s the volume of 1 box, times 5. The base area x the height is 2,673.25, and when you multiply this by 5, you get 13,366.35 cubic inches.

Answer:

13366.25in cubed

Step-by-step explanation:

To find the volume of a rectangular prism, you need the formula:

V = (L × H) × W

Luckily, L × H is the base of the shape. So we can change it into:

V = B × W

Step 1

Plug in the values! That’s what we do everytime!

V = 314.5 × 8.5

Step 2

Multiply 314.5 by 8.5.

V = 2673.25

BUT ITS NOT THE ANSWER YET!

Step 3

Because you need  to find the volume of 5 of the boxes, multiply 2673.25 by 5.

2673.25 × 5 = 13366.25

Thus, the volume of 5 of the boxes is 13366.25in cubed.
