Answer:

Step-by-step explanation:

if you solve all of them

2(4x) = 8x

a) 2 + 4x well you cant simplify more on that so no that wouldnt be the answer

b) (2 × 4)x = 8(x) = 8x

c) would equal 4 + 8x

d) 8 + 8x

hope I helped ;)

Plz Q-Q convert 3/5 into a fraction with a denominator of 20

Aliun [14]

Answer:

$\frac{12}{20}$

Step-by-step explanation:

Lets think about multiplication. What times 5 equals 20? (5x = 20)

It would be 4! (5 x 4 = 20)

So take the 4 and multiply it by the fraction.

$4 * \frac{3}{5} = \frac{4}{4} * \frac{3}{5} = \frac{12}{20}$

Theres your answer :)

Which of the following angles is in the solution set of sec2θ - 3secθ - 2 = 0 for 0° ≤ θ < 360°

Nataly_w [17]

(sec O - 1)(sec O - 2)

sec O = 1 , 2

O = 45 , 26.6 degrees These are the angles in first quadrant

Please solve these equations much appreciated

Answer:

Part c) $V=16,500\ m^3$

Part d) $V=93,312\pi\ mm^3$ or $V=292,999.68\ mm^3$

Step-by-step explanation:

Part c) Find the volume of the inverted rectangular pyramid

The volume of the rectangular pyramid is equal to

$V=\frac{1}{3}Bh$

where

B is the area of the rectangular base

h is the height of pyramid

Find the area of the base B

$B=(60)(15)=900\ m^2$

$h=55\ m$

substitute

$V=\frac{1}{3}(900)(55)$

$V=16,500\ m^3$

Part d) Find the maximum volume of tea in the tea cup

we know that

The volume of cylinder (tea cup) is equal to

$V=\pi r^{2}h$

we have

$r=36\ mm\\h=72\ mm$

substitute

$V=\pi (36)^{2}(72)$

$V=93,312\pi\ mm^3$ -----> exact value

Find the approximate value

assume

$\pi =3.14$

$V=93,312(3.14)=292,999.68\ mm^3$
