Answer:

4 pages per hour

Step-by-step explanation:

Willie and Pedro are reading the same book. Willie read 108 pages in 3 hours, and Pedro read 160 pages in 5 hours.

We find how many pages per hour each of them read.

For Willie

Willie read 108 pages in 3 hours,

3 hours = 108 pages

1 hour = x

Cross Multiply

3x = 108 pages × 1 hours

x = 108 pages/3

x = 36 pages per hour

For Pedro

Pedro read 160 pages in 5 hours

5 hours = 160 pages

1 hour = x

Cross Multiply

5x = 160 pages × 1 hours

x = 160 pages/5

x = 32 pages per hour.

How many more pages per hour did Willie read?

This is calculated as:

36 pages/hour - 32 pages per hour

= 4 pages per hour

Step-by-step explanation:

The Hypotenuse-Leg Theorem states that two right triangles are congruent if and only if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of the other right triangle.

Answer:

71 1/4 pans of lasagna

Step-by-step explanation:

From the above question:.

4 cans of tomato sauce = 1 pan of lasagna

285 cans of tomato sauce = x

Cross Multiply

4x = 285 × 1

x = 285/4

x = 71 1/4 pans of lasagna

Violet could make 71 1/4 pans of lasagna

Answer:

  19 players

Step-by-step explanation:

The total being spent is ...

  bus cost + (per player cost) × (number of players) = total raised

  250 + 25.85p = 741.15

  25.85p = 491.15

  p = 491.15/25.85 = 19

The team could bring 19 players to the tournament.

Answer:

D

Step-by-step explanation:

use a calculator next time

20% off means it is selling for 80% of the original price ( 100% - 20% =80%)

Divide the sale price by 80% as a decimal:

380/0.80 = 475

The original price was $475

Justify:

Multiply the original price by 20% and subtract:

475 x 0.20 = 95

475-95 = $380 which is the sale price.

Answer:

Step-by-step explanation:

20% off means it is selling for 80% of the original price ( 100% - 20% =80%)

Divide the sale price by 80% as a decimal:

380/0.80 = 475

The original price was $475

Justify:

Multiply the original price by 20% and subtract:

475 x 0.20 = 95

475-95 = $380 which is the sale price.

Answer:

26.56 degrees

Step-by-step explanation:

The set up will give a right angles triangle

Given

The Horizontal distance = Adjacent side = 300ft

The height = Opposite side = 150ft

Using the SOH CAH TOA identity;

tan theta = opposite/adjacent

tan theta = 150/300

tan theta = 1/2

theta = arctan 1/2

theta = 26.56 degrees

Hence the angle of elevation is 26.56 degrees

Answer:

4.2

Step-by-step explanation:

This one is pretty easy cause all you need to do is subtract 0.9 from 5.1

5.1 - 0.9 = 4.2

And to check it plug and play

4.2 + 0.9 = 5.1

Therefore, your answer is 4.2

Answer:

This graph shifted UP by 3 units

Step-by-step explanation:

The parent function of the absolute value is:

f(x) = | x |

If f(x) is reflected across the y-axis, it would map to itself. If it was reflected across the x-axis, it would map to a negative-valued function for all x.

The graph shown is not a reflection, but it's a translation. Note the parent function passes through the origin, thus the graph is a translation of 3 units up.

This graph shifted UP by 3 units

D) The car stops at a distance from the starting point because the portion shows a constant function away from the starting point.

Step-by-step explanation:

For this case, the first thing you should keep in mind is the following definition:

d = v * t

Where,

d: distance

v: speed

t: time

For the portion of the chart labeled J we have:

The time increases

The distance is the same

We have then that the speed is zero.

Therefore, the car is stopped at a distance far from the starting point.

Answer:

The question is lacking the detail of the price of the ice cream cones.

Assuming the ice cream cones cost $2 each then she would have to sell;

= 250/2

= 125 ice cream cones

If she sells 125 ice cream cones, she will be able to raise $250 if the cones are sold at $2 each.

Answer:

The height of a rectangle's side is 15 cm tall.

Step-by-step explanation:

You can use the pythagorean theorem to solve this.

The pythagorean theorem is:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

The hypotenuse represents the c. One the diagram, the hypotenuse represents the diagonal. The letters a and b represents the sides (just not the diagonals).

Let's plug in.

[tex]{a}^{2} + {b}^{2} = {c}^{2} \\ {a}^{2} + {10}^{2} = {18.03}^{2} \\ {a}^{2} + 100 = 325.0809 \\ \frac{ - 100 = - 100}{ {a}^{2} = \sqrt{225.0809} } \\ a = 15.00[/tex]

Therefore, its 15 cm.

Answer:

C.) 51

Step-by-step explanation:

1 : the quality or state of being probable. 2 : something (such as an event or circumstance) that is probable. 3a(1) : the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes. Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics. The probability of an event is a measure of the likelihood that the event will occur. The sum of probabilities of all sample points in a sample space is equal to 1. ... The probability of event A is the sum of the probabilities of all the sample points in event A. The probability of event A is denoted by P(A). The probability formula provides the ratio of the number of favorable outcomes to the total number of possible outcomes. The probability of an Event = (Number of favorable outcomes) / (Total number of possible outcomes) P(A) = n(E) / n(S)

There are three major types of probabilities:

Theoretical Probability.

Experimental Probability.

Axiomatic Probability.
