Answer:

Step-by-step explanation:

To find this you have to divide the numerators by denominators to find what number that equals so for a: 5/20 & 4/16 5/20=0.25 4/16=0.25

So the answer is a because the numbers are equivalent! Hope this helps! :)

In quadrilateral QRST, Angle R S T measures (5x+15)°. Angle TQR measures (4x+3)°. Circle P is inscribed with quadrilateral Q R S

Assoli18 [71]

Answer:

105degrees

Step-by-step explanation:

Using the theorems that states that the sum of the opposite side of the quadrilateral is 180degrees, hence;

<RST + <TQR = 180

5x+15 + 4x+ 3 = 180

9x + 18 = 180

9x = 180 - 18

9x = 162

x = 162/9

x = 18

Since <RST = 5x+15

<RST = 5(18) + 15

<RST = 90 + 15

<RST = 105degrees

Hence the measure of <RST is 105degrees

The volume of a solid right pyramid with a square base is V units3 and the length of the base edge is y units.

Evgen [1.6K]

Answer:

Height of the pyramid = 3v/y² units

Step-by-step explanation:

We are given;

- The volume of a solid right pyramid with a square base = v units³

- The length of the base edge = y units

The formula for volume of a pyramid is given as;

V = ⅓ x base area x height.

Since the base is square, we will use the formula for square area which is A = side × side.

Thus, v = ⅓ × (y × y) × height

Making height the subject, we have;

Height = 3v/y²

height of the pyramid would be given by the expression 3v/y² units

Write an equation that can be used to solve the problem. Then answer the question asked. A group of college students are volunte

svp [43]

Answer:

Required equation : $\frac{1}{t}=\frac{1}{3}+\frac{1}{9}$

Together they can paint the same room in 2.25 hours or 2 hours 15 minutes.

Step-by-step explanation:

It is given that Dale Horton can paint a certain room in 3 hours.

One hour woks of Dale Horton = 1/3

Kathy Garcia can paint the same room in 9 hours.

One hour woks of Kathy Garcia = 1/9

Let together they can paint the same room in t hours.

One hour woks of both = 1/t

$\frac{1}{t}=\frac{1}{3}+\frac{1}{9}$

$\frac{1}{t}=\frac{3+1}{9}$

$\frac{1}{t}=\frac{4}{9}$

After reciprocal we get

$\frac{t}{1}=\frac{9}{4}$

$t=2.25$

1 hour = 60 minutes.

0.25 hour = 15 minutes.

Therefore, together they can paint the same room in 2.25 hours or 2 hours 15 minutes.
