b. 3 × 108 +4 × 106 + 5 × 105 + 1 × 10²

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

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.

Answer: 92˙

Step-by-step explanation:

All 3 of the measures in a triangle must add up to 180.

Step 1: Add

39+49= 88

Step 2: Subtract to find the missing angle

180-88= 92

Hence, the measure of the missing angle is 92 degrees.

1. 4x' = 36 in

x' = 9 in

As it's increased by 6 inches we get x = 9-6 = 3 in.

An equation for this is 4x'/4-6 = x

Answer:

$45

Step-by-step explanation:

Solution

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

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.

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

The only reason you may have got confused with this question is from not knowing the conversions or measurements. This is a 2-step questions were you have to convert then do the main equations to solve.

Answer:

4 hours

Explanation:

[tex]\sf time = \dfrac{distance}{speed}[/tex]

Here the units are same for both, so no need of conversion.

Solve:

time taken = distance/speed

time taken = 320/80

time taken = 4 hours

Answer:

4 hours

Step-by-step explanation:

[tex]\text{Speed} =\frac{\text{distance} }{\text{time} }[/tex]

Then

[tex]\text{time} =\frac{\text{distance} }{\text{speed} }[/tex]

Then

[tex]\text{time} =\frac{\text{320} }{\text{80} } =4[/tex]

Answer:

C or D

Step-by-step explanation:

its either one of those two but go woth which ever you thuink

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.

Answer:

(a) Describe the rule for translating center Q onto center P.

center P(2, 0)

center Q(0, 4)

you would need to add 2 units in x axis, and subtract 4 units on y axis.

(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.

they are similar because a similarity transformation (translation, dilation) exists between them

Step-by-step explanation:

Circle Q' is formed by dilating Circle Q by a factor of 10.

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

To Describe the rule for translating center Q onto center P.

center P(2, 0) and center Q(0, 4)

We would need to add 2 units on x-axis, and subtract 4 units on y-axis.

To find the scale factor for dilating circle Q ,so that it has the same radius as circle P.

P radius 20, Q radius 2, radius Q x 10 = radius P, so the scale factor is 10

It is found that they are similar because a similarity transformation (translation, dilation) exists between them.

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.

A= x+16

A= 3+16

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%

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

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.
