HELP FIRST TO ANSWER ALL IS BRAINLEIST!!!!!!!!!​
andreev551 [17]

Answer:

1. D) 1 9/20

2. B) 7/12

4. D) $50.00

Step-by-step explanation:

The working is as follows :

1. Mrs. Lang bought 3/4 pound of red grapes and 7/10 pound of green grapes. To find out how many are in total we have to add both values total.

3/4 + 7/10

The LCM of 4 and 10 is 20.

3/4 * 5 = 15/20

7/10 * 2 = 14/20

15/20 + 14/20 = 29/20 = 1 9/20

2. 1/3 + 1/4

The LCM of 3 and 4 is 12

1/3 * 4 = 4/12

1/4 * 3 = 3/12

4/12 + 3/12 = 7/12

4. Sharon spent 2/3 of her clothing allowance; she was given $75. All we have to do is find 2/3 of $25 :

2/3 * $75 = $50.00

Factor 16x^3+16x^2+3x
oee [108]

Answer:

x(4x + 3)(4x + 1).

Step-by-step explanation:

16x^3 + 16x^2 + 3x

First take out the x:

= x(16x^2 + 16x + 3)

= x(16x^2 + 4x + 12x + 3)

= x(4x(4x + 1) + 3(4x + 1))

= x(4x + 3)(4x + 1)  (answer).

What is the area of the half circle below?2 Pi 4pi 8pi 16pi
Reika [66]

Answer:

A = 8π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 8 , then r = 8 ÷ 2 = 4

The area of half a circle is then

A = \frac{1}{2} π × 4² = \frac{1}{2} × π × 16 = 8π cm²

Help? Please? Mathematics isn't my thing.
Natali5045456 [20]
C is the correct answer. The equation for f(x) is f(x)=1.8x-10 and the equation for g(x) is g(x)=-4 . Since we're trying to find the input value for x where f(x)=g(x) make the 2 equations equal to each other and you'll get your answer.
