Answer:

337.35 mi/h^2

Step-by-step explanation:

Given the equation;

v= u +at

v= final velocity = 51 mi/h

u= initial velocity = 23 mi/h

t = time = 5 mins or 0.083 hours

a = acceleration, the unknown

51 = 23 + 0.083a

51 - 23 = 0.083a

a= 51 - 23/0.083

a= 337.35 mi/h^2

Answer:

First you find how many pounds for 1 litre of blood. Trick is if you divide x by y, the answer you get will follow the unit of x. So if you divide 150 pounds by 4.5 litres, the answer will be 33.33 pounds per litre. So how many 33.33... is there in 250? Just divide 250 by 33.333 or (150/4.5), you'd get 7.5. That means for there's 7.5 parts of 33.333 pounds in 250 pounds. And if 33.333 pounds is equal to 1 litre of blood, you get 7.5 liter!

Answer:

Use Close Call to practice two-digit addition or subtraction. The best math card games are simple at heart. To play Close Call, each player deals themselves four cards then determines how to arrange them so they make two two-digit numbers that add up as close as possible to 100 without going over.

Answer: Yes.

Step-by-step explanation: Because if it is 0 on the x axis then no matter what the Y number is it will be on the line.

Answer:

C, 2(x-3) = 22

Step-by-step explanation:

2(x-3) = 22

2((14)-3) = 22

2(14-3) = 22

2(11) = 22

22 = 22

Answer and Step-by-step explanation: In math, a graph, function or equation can be alterated - by shifting, reflecting, stretching or compressing - without losing its original shape. For example, a quadratic function maintains its parabolic shape when shifted.

When an equation is transformed vertically, it means its y-axis is changed. When it is horizontally, its x-axis is modified.

For equation [tex]y=x^{3}[/tex]:

This means the exponential equation will be multiplied by a constant, in this case 3. Then, the new equation is

[tex]y=3x^{3}[/tex]

When an equation is shifted, it's added a constant to it. As it is horizontal, it means it is added to the x and because it is to the right, it is a plus symbol:

[tex]y=x^{3+4}[/tex]

Vertical shift means the equation is 3 units "below" the original equation, so:

[tex]y=x^{3}-3[/tex]

Answer:

The midpoint is at 20

Step-by-step explanation:

The midpoint of a segment

Given a segment in the number line with endpoints A(xa) and B(xb).

The midpoint coordinate is calculated as follows:

[tex]\displaystyle xm=\frac{xa+xb}{2}[/tex]

We are given the coordinates xa=10 and xb=30, thus the coordinate xm of the midpoint M is at:

[tex]\displaystyle xm=\frac{10+30}{2}[/tex]

[tex]\displaystyle xm=\frac{40}{2}[/tex]

xm = 20

The midpoint is at 20

Answer:

A numerator is allowed to take on the value of zero in a fraction. Any legal fraction (denominator not equal to zero) with a numerator equal to zero has an overall value of zero. all have a fraction value of zero because the numerators are equal to zero.

Answer:

21.58 miles

Step-by-step explanation:

First let's find how many miles Alex walked.

It said "Alex walked five times as many miles as Sue" so lets multiply 3.38 with 5: 3.38 x 5 = 16.9

So, Alex walked 16.9 miles. Now we can find Dan's.

It said "Dan walked 4.68 miles more than Alex" so lets add 4.68 to 16.9: 16.9 + 4.68 = 21.58

So Dan walked 21.58 miles

Answer:

a. No

b. Yes

Step-by-step explanation:

a.

x - 4 = 12

x - 4 + 4 = 12 + 4

x = 16

16 ≠ 8

Therefore, the following value given for problem a is not a solution to the given equation.

b. (3 + x)/4 = 3

(3 + x)/4 * 4 = 3 * 4

3 + x = 12

3 + x - 3 = 12 - 3

x = 9

9 = 9

Therefore, the following value given for problem b is a solution to the given equation.

Answer: c

Step-by-step explanation: I got it right on the test

A′ (0, 4), B′ (4, 0), C′ (8, 8)

Using a trigonometric identity, it is found that the statement is False.

It is for the sine squared, given by:

[tex]\sin^2{x} = \frac{1 - \cos{(2x)}}{2}[/tex]

In this problem, the equality given is:

[tex]\sin{\left(\frac{x}{7}\right)} = \frac{1 - \cos{\left(\frac{2x}{7}\right)}}{2}[/tex]

Since the left side does not have the sine squared, the identity is not valid and the statement is False.

Answer:

53 ounces

Step-by-step explanation:

We know that,

1 pound = 16 ounce

3 pounds = 48 ounces

We need to find the weight in 3 pounds, 5 ounces.

3 pounds, 5 ounces = 48 ounces+ 5 ounce

= 53 ounces

So, the scale weight is 53 ounces. Hence, the correct option is (b).

Answer:

Part 1: Answer the following questions (20 points)

1. Name and describe the components needed to make a complete circuit.

. battery

. connecting wire

. resister  

. voltmeter

. ammeter

2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.

They both give off electricity energy, and they are different because they don't release the same amount of energy

3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.

In accordance with the law, if r became smaller, and V stayed the same, the current would increase. The increases would be inversely proportional to the resistance, if the resistance was halved, the current would double.

4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it

Step-by-step explanation:

A value is excluded when it makes the rational expression undefined. (such as making the denominator 0, etc.)

For example when x = 8, (x - 8) at the denominator will become 0 and make it undefined.
