Answer:

x = -16/-30 or x = .54

Step-by-step explanation:

-4(6x - 7) - 3(4 + 2x)

-24x + 28 - 12 - 6x

combine like terms

-30x + 16

subtract 16 from both sides

-30x = -16

divide by -30

x = -16/-30 0r x = .54

A cube has a side length of 7 cm a cylinder has a radius of 5 cm and a height of 4 cm

densk [106]

Answer:

Cube has larger volume than cylinder.

Step-by-step explanation:

Given:

Side of a cube = 7 cm

Radius of a cylinder (r) = 5 cm

Height of a (h) = 4 cm

Find:

Larger volume = ?

Computation:

Volume of cube = Side³

Volume of cube = 7³

Volume of cube = 343 cm³

$Volume\ of\ cylinder=\pi r^2h\\\\Volume\ of\ cylinder=\frac{22}{7} (5)^2(4)\\\\Volume\ of\ cylinder= 314.28$

Cube has larger volume than cylinder.

A group of 5 families at Baileys Middle School sold magazine subscriptions to raise money for the school. $6.00, $7.00, $4.00,

mash [69]

Answer:

The median amount of money raised is $5.00

Step-by-step explanation:

To find the median amount of money raised, we will follow the steps below:

First, arrange the data giving in ascending order. That is

$6.00, $7.00, $4.00, $5.00, $3.00

We will arrange it in ascending order, hence

$3.00, $4.00, $5.00, $6.00, $7.00

The median is the middle number, we will now proceed to take the middle number.

The middle number is $5.00

Therefore, the median amount of money raised is $5.00

An arrow is shot vertically upward at a rate of 160 feet per second from ground level. Use the projectile formula

Bumek [7]

Answer:

after 10 seconds

Step-by-step explanation:

h=-16t^2+v0*t+h0

ground level is h0 with a measure of 0

160 is v or velocity

0=-16t^(2)+160t+0

0=-16t^(2)+160t

0=16t(-t+10)

0/16t=(-t+10)

0=-t+10

-10=-t

10=t

t=10

Roberta needs ribbon for a craft project. The ribbon sells for $3.74 per yard. Find the cost, in dollars, for 48 inches of the r

almond37 [142]

You have to convert 1 yard to 36 inches. so you do 3.74×3.74(1/3) because the extra 12 inches is one third of a yard. You eventually get 4.986 which rounds to 4.99

What is 100 written as a product of prime factors

Airida [17]

The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50 and 100. To find the prime factorization, first take any two of the factors that multiply to make 100. For instance, 25 x 4 = 100. Neither 25 nor four is a prime number, so each must be broken down further
There you go =)
