what is the value of x??? please help me easy math question

Answers

Answer:

x = 30

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

60 + x+3x = 180

60 + 4x = 180

Subtract 60 from each side

60+4x-60 = 180-60

4x = 120

Divide by 4

4x/4 = 120/4

x = 30

You buy milk at $3.48 per gallon. One portion of oatmeal requires 5 ounces of milk. How much does the milk for one portion cost? Round to the nearest cent.

Answers

Answer: $0.1359375

Step-by-step explanation:

First and foremost, we should note that 1 gallon = 128 ounce. Therefore, $3.48 per gallon simply means $3.48 for 128 ounce. Therefore, the cost per ounce will be:

= $3.48 / 128

= $0.0271875

Therefore, the amount for the the milk for one portion cost which requires 5 ounces of milk will be:

= $0.0271875 × 5

= $0.1359375

What is the diameter of a hemisphere with a volume of 651 m^3, to the nearest tenth
of a meter?

Answers

Answer: 13.5 m, hope this helps :)

If the volume of the sphere is 651 m³. Then the diameter of the sphere will be 10.75 meters.

What is the volume of the sphere?

If the given sphere is of radius r units, then its volume is given as:

V = 4/3 πr³ unit³

The volume of the sphere is 651 m³.

Then the diameter of the sphere will be

We know the formula in the form of diameter.

V = 1/6 πd³ unit³

Then we have

651 = 1/6 πd³

πd³ = 3906

 d³ = 1243.31

  d = 10.75 m

plss help no link im giving brainless i need it Asap​

Answers

Answer:  C) 13 gallons

============================================================

Work Shown:

(150 miles)/(6 gallons) = (325 miles)/(x gallons)

150/6 = 325/x

150*x = 6*325 .... see note below

150x = 1950

x = 1950/150 .... divide both sides by 150

x = 13 gallons is the final answer

But that's not sufficient, as it would show that bend being at 0, 0. Instead, we need to translate it two units to the left, giving us:

A rectangular lawn has an area of 1624 square metres. Its perimeter is 170 metres. What are the dimensions of the lawn?

Answers

GIVEN

L×B = 1624. ---1)

2(L+B) = 170

(L+B) = 85

L= 85- B

Substitute value of L in eq 1)

(85-B)B = 1624

B²-85B+1624 = 0

B²-56B-29B+1624 = 0

B(B-56)-29(B-56) = 0

(B-29)(B-56) = 0

B= 29 OR B= 56

IF B = 29, L = 56

IF B = 56, L = 29

The dimension of lawn is 56×29 cm²

Write a function rule for the area A(h) of a parallelogram whose base is 3 units more than its height h.

A. A(h) = h2 + 3
B. A(h) = h2 + 3h
C. A(h) = h2 + 3h + 3
D. A(h) = h + 3h

Answers

Answer:  h^2+3h   (Choice B)

===================================================

Work Shown:

height = h

base = h+3, since the base is 3 more than the height

area = base*height

area = h*(h+3)

area = h*h + h*3

area = h^2+3h

Draw a square with one vertex on the origin (-3, 5) and a perimeter of 20.

Answers

Answer:

Coordinates:

(-3, 5)

(2, 5)

(-3, 10)

(2, 10)

Step-by-step explanation:

Perimeter formula:

length + width + length + width

Insert known value(s):

l + w + l + w = 20

Squares must have the same value for all 4 sides, so what number × 4 will equal 20? 5.

5 + 5 + 5 + 5 = 20

This means coordinates will be 5 units apart:

(-3 + 5, 5) = (2, 5)

(-3, 5 + 5) = (-3, 10)

Mark these coordinates on your grid as you go to double check the shape turns becomes a square:

(2, 5 + 5) = (2, 10)

Counting between them should equal 5 units for each side: I checked using the desmos graphing calculator online.
