20% of the students in the class play an instrument. if there are 35 students in class, how many play an instrument?

Answer:

h = -9

Step-by-step explanation:

2(h + 3.5) = -11

2h + 7 = -11

subtract 7 from both sides of the equation:

2h = -18

divide both sides by 2:

h = -9

We are given that there is a 20% sale in the store. Moreover, the sale price of an item is p - 0.2p, where p is the price of the item. So, we get that, p - 0.2p is equivalent to 0.8p

Step-by-step explanation:

∠ KNM and ∠ KRQ are corresponding angles and are congruent , then

∠ KRQ = 146°

Answer:

The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.

Step-by-step explanation:

From Analytical Geometry, we have the Equation of the Distance of a Line Segment between two points:

[tex]l_{AB} = \sqrt{(x_{B}-x_{A})^{2} + (y_{B}-y_{A})^{2}}[/tex] (1)

Where:

[tex]l_{AB}[/tex] - Length of the line segment AB.

[tex]x_{A}, x_{B}[/tex] - x-coordinates of points A and B.

[tex]y_{A}, y_{B}[/tex] - y-coordinates of points A and B.

If we know that [tex]l_{AB} = 15[/tex], [tex]x_{A} = -8[/tex], [tex]x_{B} = 1[/tex] and [tex]y_{B} = 2[/tex], then the possible coordinates of point A is:

[tex]\sqrt{(1+8)^{2}+(2-y_{A})^{2}} = 15[/tex]

[tex]81 + (2-y_{A})^{2} = 225[/tex]

[tex](2-y_{A})^{2} = 144[/tex]

[tex]2-y_{A} = \pm 12[/tex]

There are two possible solutions:

1) [tex]2-y_{A} = -12[/tex]

[tex]y_{A} = 14[/tex]

2) [tex]2 - y_{A} = 12[/tex]

[tex]y_{A} = -10[/tex]

The possible coordinates of point A are [tex]A_{1} (x,y) = (-8, 14)[/tex] and [tex]A_{2} (x,y) = (-8, -10)[/tex], respectively.

Answer:

3 = 1/6 chance 4 = 1/6 chance

Step-by-step explanation:

BECAUSE there are 6 numbers on a number cube and there is no ganruntee that it will land on 4 or 3 so its a 1/6 chance that it will land on them.

Answer:

1/6

Step-by-step explanation:

A dice (Number cube in this case) has six sides, in only which one side is three and one side is 4.

Answer:

36 square feet

Step-by-step explanation:

To get the answer you need to find the area of the triangle and subtract area of the rectangle.

7*12/2 = 42

42 - 3*2 = 36

Step-by-step explanation:

The function crosses the y-axis at (0, -3)

A nearby maximum can be found at (1.57, -2) or (π/2, -2)

A nearby maximum can be found at (3.14, -2) or (π, -2)

Answer:

1/32

Step-by-step explanation:

So we know that green shirts can be represented by 1/4 of 1/8. It's 1/4 of the 1/8 of shirts in the store. The key word here is "of," which means multiplication.

So you can replace 1/4 of 1/8 with:

[tex]\frac{1}{4} x \frac{1}{8}[/tex]

To multiply fractions, it's really simple: multiply the denominator with the denominator and the numerator with the numerator.

[tex]\frac{1}{4} x \frac{1}{8} = \frac{1}{32}[/tex]

So 1/32 of the entire store is green shirts.

Answer:

520 cubic centimeters (cm^3)

Step-by-step explanation:

volume = length * width * height

length = 13

width = 5

height = 4 + 4, so height = 8

volume = (13) * (5) * (8)

volume = 520 units

Since the given measurements are in centimeters and the answer is the volume of the prism, the answer must be in cubic centimeters

So, the final answer is 520 cubic centimeters (cm^3)

Answer:

D  36πa^6b^9

Step-by-step explanation:

Step 1. Write the formula for the volume of a sphere.

V = (4/3)πr³

Step 2. Replace r with the given radius. Since the given radius is an expression, remember to enclose it in parentheses and cube the entire expression.

V = (4/3)π(3a²b³)³

Step 3. Simplify the expression. Start by cubing each factor inside the parentheses.

V = (4/3)π ×(3)³(a²)³(b³)³

To raise an exponent to an exponent, multiply the exponents.

V = (4/3)π × 27a^6b^9

V = (4/3 × 27)πa^6b^9

V = 36πa^6b^9

Answer: D  36πa^6b^9

Answer:

[tex]\dfrac{-79}{126}[/tex]

Step-by-step explanation:

The given expression is :

[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}[/tex]

The LCM of 3,7,9 and 14 is 126

So,

[tex]\dfrac{-2}{3}+\dfrac{5}{7}+\dfrac{-8}{9}+\dfrac{3}{14}=\dfrac{42(-2)+18(5)+14(-8)+9(3)}{126}\\\\=\dfrac{-79}{126}[/tex]

So, the value of the given expression is equal to [tex]\dfrac{-79}{126}[/tex].
