Answer:

240 should be the answer

Step-by-step explanation:

80% of 300 is 240

Answer:

The correct answer would be 240. If you start at 10 percent which already gives you 30 then continue to go up. Move on by 10 percent until you get to 80 percent which is the amount of televisions that are high definition. Once you count by 10 percent with 30 everyitme you will lead to the answer of 240.

Step-by-step explanation:

Just count by 30’s eight times and you get your answer which I supplied above. I hope this helps.

Step-by-step explanation:

Answer:

If m<1 = 38 then m<4 = 38

Step-by-step explanation:

Both of the angles equal 38 degrees. This is true because the angles are vertical, vertical angles are angles opposite each other where two lines cross. Vertical angles are also always congruent, therefore the m<4=38.

Answer:

8%

Step-by-step explanation:

Mathematically, the probability of an event can be obtained by dividing the expected number in which event will turn up divided by the total number we have in the sample space

From the question, the total number of times in which the experiment is performed is 38 times

The number of times we have the peach chew selected is 3 times

So the probability that the next removal will be a peach chew will be;

3/38 = 0.079

This as a percent is 7.9%

To the nearest whole number, this figure is 8%

Answer:

C = 0.68w + 3.25t

C is total cost

Step-by-step explanation:

"Interpret the rate of change and the y-intercept.

"

Rate of change is 5. Each ticket costs 5$.

Y-intercept is (0,-17). They spent $17 on supplies before they sold tickets.

Answer:

C Neither positive nor negative—the sum is zero.

Step-by-step explanation:

Given the expression

(1/23)+(-1/23)

Required

The sign of the resulting expression

Note that the product of a minus and a plus sign is minus sign i.e (-×- = +)

The equation becomes;

= 1/23 - 1/23

= 0/23

= 0

Hence the resulting value is neither positive nor negative since the sum is zero

Answer:

The airplane’s rate of change in elevation is 34.5 m/s.

Step-by-step explanation:

Given that,

An airplane descended 345 m in 10 seconds.

We need to find the airplane’s rate of change in elevation. Let the rate is R. Its rate is equal to the distance divided by time. So,

[tex]R=\text{velocity}=\dfrac{345\ m}{10\ s}\\\\=34.5\ m/s[/tex]

So, the airplane’s rate of change in elevation is 34.5 m/s.

Answer:

$43.2

Step-by-step explanation:

32.4÷15=2.16

2.16×20=43.2

The cost of purchasing 20 gallons of gas will be $43.2.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

The costs Jason $32.40 to purchase 15 gallons of gas.

Now,

Let the cost of purchasing 20 gallons of gas = x

Since, The costs Jason $32.40 to purchase 15 gallons of gas.

So, By definition of proportion we get;

⇒ $32.40/15 = x / 20

⇒ 32.40 × 20 / 15 = x

⇒ x = $43.2

Thus, The cost of purchasing 20 gallons of gas = $43.2

Answer:

y = 9x cents

y = (36 + 3x) cents

Step-by-step explanation:

Given that:

Newtown telephone company :

Fee per minute = 9c

Tyrus company :

Fee per minute = 3c

Connection fee = 36c

Cost equation :

y = total cost for each phone call:

x = minutes phone call last ;

Newton Company :

y = (fee per minute * minute phone call last)

y = 9 * x

y = 9x cents

Tyrus Company:

y = (connection fee + (fee per minute * minute phone call last))

y = (36 + (3 * x))

y = (36 + 3x) cents

If the given points in the table lie on a line, then the slope of a line is, 4

Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.

So formula for the slope is,

m = change in y coordinate/change in x coordinate = Δy/Δx

Given that,

Coordinates of a point through which line is passing,

X:   1    3    5    7

Y:   2   10  18  26

The slope of a line  =  ?

The slope of a line can be calculated by finding the rise (difference in the y-values) over the run (difference in the x-values) between two points on the line.

Now, Using the first and last points in the table:

First point- (1, 2)

Second Point- (7, 26)

Slope =  (y₂ - y₁)/(x₂ - x₁)

Slope = (26 - 2) / (7 - 1)

          = 24 / 6

          = 4

The slope of the line is 4.

x = 10

Answer: x = -1

Step-by-step explanation: Insert all the numbers into x, and when you insert -1 to x, you get 40.

Answer:

x = - 1

Step-by-step explanation:

Given

- 4(3x - 7) = 40 ( divide both sides by - 4 )

3x - 7 = - 10 ( add 7 to both sides )

3x = - 3 ( divide both sides by 3 )

Answer:

As

[tex]\left(x^3+2x^2+5\right)-\left(8x^2-4x+6\right)=x^3-6x^2+4x-1[/tex]

Therefore, option D is the correct answer is.

Step-by-step explanation:

Given the expression

[tex]\left(x^3+2x^2+5\right)\:-\:\left(8x^2\:-\:4x\:+\:6\right)[/tex]

solving to simplify the expression

[tex]\left(x^3+2x^2+5\right)\:-\:\left(8x^2\:-\:4x\:+\:6\right)[/tex]

[tex]=x^3+2x^2+5-\left(8x^2-4x+6\right)[/tex]        ∵  [tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]

[tex]=x^3+2x^2+5-\left(8x^2-4x+6\right)[/tex]
