Answer:

5

Step-by-step explanation:

Given the profit equation ;P(x)

x = number of units sold

P(x) = profit made

P(x) = 101

101 = 0.2x^2+20x-4

0.2x^2+20x-4 - 101

0.2x² + 20x - 105 = 0

Using the formula:

-b±[sqrt(b² - 4ac) / 2a]

Where ;

a = 0.2 ; b = 20, c = - 105

Using the quadratic equation solver to save time :

The roots are :

-105 and 5

Items sold cannot be negative ;

Hence, x = units sold = 5

Answer:

y = 10.5qt

x = 12 qt

Step-by-step explanation:

0.6x+ 0.36y = 22.5 * 0.2

0.06x + 0.36y = 4.5

x + y = 22.5

x = 22.5 - y

0.06(22.5 - y) + 0.36y = 4.5

1.35 - 0.06y + 0.36y = 4.5

0.3y = 4.5 - 1.35

0.3y = 3.15

y = 3.15 / 0.3

y = 10.5 qt

x = 22.5 - y

x = 22.5 - 10.5

x = 12 qt

Answer:

3

Step-by-step explanation:

To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values using two given points. I will use the first and last points.

(1, -2) & (13, 34)

(34 - (-2)) / (13 - 1)

Simplify the parentheses.

= (34 + 2) / (12)

= 36/12

Simplify the fraction.

36/12

= 3

This is your slope.

Hope this helps!

Answer:

Step-by-step explanation:

Answer:

in right angled triangle MNO

relationship between base and hypotenuse is given by cos angle

cosx°=b/h

cosx°=OM/MN

x°=cos-1(26/99)=74.77=74.8°

Answer:

∠ M ≈ 74.8°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos M = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{MN}[/tex] = [tex]\frac{26}{99}[/tex] , then

∠ M = [tex]cos^{-1}[/tex] ([tex]\frac{26}{99}[/tex] ) ≈ 74.8° ( to the nearest tenth )

Answer:

0.00852 miles per hour

Step-by-step explanation:

Given that:

Distance = 7.5 feets

Time taken = 10 minutes

Speed = distance / time taken

Speed = 7. 5 feets / 10 minutes = 0.75 feets / minutes

Converting to miles per hour :

0.75 feets / minute :

1 mile = 5280 feets

1 minute = 1/60 = 0.0166666 hour

0.75 feets / minute = (0.75/5280)mile / 0.0166666

= 0.0001420 / 0.0166666 mile per hour

= 0.0085200 miles per hour

= 0.00852 miles per hour

Answer:

trapezoid.

Step-by-step explanation:

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

It has 4 vertices and edges

If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram

Area of a trapezoid = [tex]\frac{1}{2}[/tex] x (sum of the lengths of the parallel sides) x height

Perimeter =  sum of lengths of sides of a trapezoid

Given:

A recipe uses 4 pounds of rice and 5 quarts of boiling water.

To find:

The rate of rice to quarts of water for this recipe.

Solution:

We need to divide the amount of rice by amount of water to get the rate of rice to quarts of water for this recipe.

[tex]\text{Required rate}=\dfrac{\text{Rice in pounds}}{\text{Water in quarts}}[/tex]

[tex]\text{Required rate}=\dfrac{4}{5}[/tex]

[tex]\text{Required rate}=0.8[/tex]

Therefore, the  rate of rice to quarts of water for this recipe is 0.8.

Answer:

16

Step-by-step explanation:

(200*2)/25=16

Answer:

Infinately many solutions.

Step-by-step explanation:

2x-4=2(x-2)

Distribute

2x-4=2*x-2*2

2x-4=2x-4

Since both sides are the same, there are infinately many solutions.

Hope this helps!

but I dont :) goodluck tho

Answer:

Note that the three identities above all involve squaring and the number 1.You can see the Pythagorean-Theorom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.. We have additional identities related to the functional status of the trig ratios:

Answer:

The Y intercept is two

Step-by-step explanation:

The y intercept is the point on a graph where the graph crosses the y axis.

Basically, it is the value of y when x is 0 is (x,y)

Looking at the attached graph, our y intercept is (0,2), meaning that the y-intercept is 2.

The answer is: the Y-INTERCEPT is 2

Answer:

150 miles

Step-by-step explanation:

x = 30y

5 inches x 30 = 150 miles

Answer:

x > 25

Step-by-step explanation:

3(2x−8)>4x+26

Step 1: Simplify both sides of the inequality.

6x−24>4x+26

Step 2: Subtract 4x from both sides.

6x−24−4x>4x+26−4x

2x−24>26

Step 3: Add 24 to both sides.

2x−24+24>26+24

2x>50

Step 4: Divide both sides by 2.

Answer:

10.6

Step-by-step explanation:

Answer:

x = 122°

Step-by-step explanation:

since it is a right triangle, the sum of the other 2 interior angles = 90°

the angle opposite x = 90° - 32° = 58°

58° and angle x are supplementary angles. Their sum is 180°.

180° - 58° = 122°
