30% is equal to 0.3 as a proportion

Multiply 50 by 0.3 to get the number of students who play soccer.

50 X 0.3 = 15

Answer:

15

Step-by-step explanation:

football and track =50% =25 students

20% of 50 is =10 students then 25 +10 =35-50=15 students which is how many plays soccer

The value of this expression if a = -7 and b = -3 is -352

Equation is an expression used to show the relationship between two or more numbers or variables.

Given that a = -7 and b = -3

Hence:

a³ - b²

Substituting the values of a and b:

= (-7)³ - (-3)²

= -343 - 9

Simplifying the equation:

= -352

a³ - b² = -352

The value of this expression if a = -7 and b = -3 is -352

Answer:

x = 50°

x = 70°

Step-by-step explanation:

A right angle is indicated by a small box.

The angles shown are right angles = 90° each. Therefore:

✔️x + 40° = 90°

Subtract 40° from each side

x = 90° - 40°

x = 50°

✔️x + 20° = 90°

Subtract 20° from each side

x = 90° - 20°

x = 70°

Answer:

200 pounds

Step-by-step explanation:

We can write a proportion to represent the problem. Let's take x as the weight of 5 televisions. If we know that 4 televisions weigh 160 pounds we can write: 4/160. Then, 5 televisions will weigh x pounds which is 5/x. Now, we can set up a proportion: 4/160 = 5/x

Cross multiply to get: 4x = 800

Isolate x: x = 800/4

Solve: x = 200

200 pounds

This is an example of

C. simultaneous causality.

Step-by-step explanation:

Simultaneous causality eliminates the conclusion that is often taken for granted to the effect that one variable is a response variable while the other is an explanatory variable because the two variables, the price and the number of shares, influence each other at the same time.  When more shares are traded than demanded in the stock market in any day, the price tends to go down, and vice versa.

Answer:

17x+44+51 = 180

x=5

Step-by-step explanation:

The angles in a triangle add to 180, so set up the equation by adding the measures of each angle on one side and putting 180 on the other side, then solve:

17x+44+51 = 180

17x+95=180

17x=85

x=85/17=5

Answer:

The statement "[tex]\angle BAF[/tex] and [tex]\angle EAB[/tex] are complimentary" is false.

Step-by-step explanation:

Complimentary angles are defined by angles that add up to [tex]90^{\circ}[/tex]. Angles BAF and EAB represent one side of a line, which is [tex]180^{\circ}[/tex]. Therefore, they are actually supplementary and not complimentary. Thus, the statement "[tex]\angle BAF[/tex] and [tex]\angle EAB[/tex] are complimentary" is false.

Answer:

Perimeter=56 units

Area =196 square unites

Step-by-step explanation:

The diagonal would be 14√2.

The formula for area using the diagonal is 1/2d².

1/2x(14√2)²=1/2x196x2=196

For perimeter, s²+s²=392

2s²=392

s²=196

s=√196

s=14

14x4=56

Answer:

Option B

Step-by-step explanation:

Scale factor by which the dimensions of the new box was dilated = [tex]\frac{1}{2}[/tex]

In other words, dimension scale factor = [tex]\frac{1}{2}[/tex]

Relation between volume scale factor and dimension scale factor is,

Volume scale factor = (Dimension scale factor)³

Therefore, volume scale factor of the smaller box = [tex](\frac{1}{2})^3[/tex]

                                                                                   = [tex]\frac{1}{8}[/tex]

Since, volume scale factor = [tex]\frac{\text{Volume of the dilated figure}}{\text{Volume of the original figure}}[/tex] = [tex]\frac{1}{8}[/tex]

Therefore, volume of the smaller box = Volume of the larger box

Option B will be the answer.

Answer:

(SEE ATTACHED PICTURE)

Step-by-step explanation:

You put a circle above the number used in the inequality.

The circle is closed if the inequality is greater than or equal to, or less than or equal to. This indicates that the number is included.

The circle is open if the inequality is greater than, or less than. This indicates that the number is not included.

The arrow goes to the left if it is less than, and to the right if it is greater than.

So, for your problem, an open circle goes about the number 4 and points left.

the answer is that you get the same outcome

Answer:

  x = y = 12

Step-by-step explanation:

A right triangle with a 45° angle is an isosceles right triangle. That means the legs are both the same length. The side ratios of such a triangle are ...

  1 : 1 : √2

Multiplying these ratios by 12 gives ...

  12 : 12 : 12√2 = x : y : 12√2

The side lengths x and y are both 12 units.

Answer:

The rocket will hit the ground after about 11.63 seconds.

Step-by-step explanation:

A rocket is launched from a tower. Its height y in feet after x seconds is modeled by the equation:

[tex]y=-16x^2+181x+59[/tex]

We want to determine the time at which the rocket will hit the ground.

If it hits the ground, its height y above the ground will be 0. So, we can set y = 0 and solve for x:

[tex]0=-16x^2+181x+59[/tex]

Solve the quadratic. Factoring is too tedious or impossible, and completing the square is also very tedious. So, we can use the quadratic formula:

[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In this case, a = -16, b = 181, and c = 59. Substitute:

[tex]\displaystyle x=\frac{-(181)\pm\sqrt{(181)^2-4(-16)(59)}}{2(-16)}[/tex]

Evaluate:

[tex]\displaystyle x=\frac{-181\pm\sqrt{36537}}{-32}[/tex]

Simplify:

[tex]\displaystyle x=\frac{181\pm\sqrt{36537}}{32}[/tex]

Hence, our solutions are:

[tex]\displaystyle x=\frac{181+\sqrt{36537}}{32}\approx 11.63\text{ or } x=\frac{181-\sqrt{36537}}{32}\approx-0.32[/tex]

Since time cannot be negative, we can ignore the second solution.

So, the rocket will hit the ground after about 11.63 seconds.

Answers:

1. 24 cans/lb x 15,000 lb/trailer = 360,000 cans/trailer

2. Answer will depend on your price per can or per pound. For example, if price is 60 cents per pound: $0.60/lb x 15,000 lb = $9,000

3. 15,000 lbs/trailer / 30 lbs/collector = 500 can collectors/trailer

4. 15,000 lbs/trailer / 800 lbs/bale = 18 complete bales (and 3/4 of another bale)/trailer

5. 24 cans/lb x 800 lb/bale = 19,200 cans / bale

6. 100 bales/boxcar x 800 lbs/bale = 80,000 lb. cans / boxcar

7. 100 bales/boxcar x 19,200 cans/bale = 1,920,000 cans / boxcar

8. Answer will depend on your price per can or per pound. For example, if price is 60 cents per pound: $0.60/lb x 80,000 lb/boxcar = $48,000/boxcar
