Answer:

8 inches

Step-by-step explanation:

A shipping company has 3 different sized cubed boxes.

The volume of the boxes are 216in³,512in³,and 1000in³

We find the height of each volume of box.

a) 216in³,

Volume = h³

Height = cube root (216)

= 6 in

b) 512in³

= Volume = h³

Height = cube root (512)

= 8 in

c) 1000in³

Volume = h³

Height = cube root (1000)

= 10 in

Since: Mia needs to ship a gift with a height of 7 in .

Therefore: the height in inches of the smallest box that Mia can use is 8 inches (8 in)

Answer:

f(8) = -161

Step-by-step explanation:

Plugin 8 to each x value to get to this equation, -3(8)^2 + 3(8) + 7.  Once you have done that, make sure to multiply 8 to the second power and by 3 separately to get to this equation -3(64) + 24 + 7.  Combine 24 and 7 together to get 31 and multiply 64 by -3 to get -192.  Add 31 now to get -161 as your answer.

Answer:

f(8)= -161

Step-by-step explanation:

fill in 8 into x, so the equation becomes

f(8)=-3(8)^2+3(8)+7

f(8)=-3(64)+24+7

f(8)=-192+31

f(8)=-161

Step-by-step explanation:

4x3=12 tins of white paint

12+4=16 total tins

The total number of tins used by the Peony will be 16.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.

Given that Peony mixes red paint and white paint in a ratio of 1:3 She uses four tins of red paint.

The Number of red tins,

R = 4 x 1 = 4

The number of white tins,

W = 4 x 3 = 12

Total number of tins,

T = R +W

T = 4 + 12

T = 16

Therefore, the total number of tins used by the Peony will be 16.

Answer:

y = 5/4x + 10

Step-by-step explanation:

First, we need to use point-slope form which is:

y - y₁ = m(x - x₁)

Now, we substitute the numbers:

y - 5 = 5/4(x - (-4))

y - 5 = 5/4(x + 4)

y - 5 = 5/4x + 5

y = 5/4x + 10

You can check by substituting the points into the equation:

5 = 5/4(-4) + 10

5 = -5 + 10

5 = 5

Answer:

E. If two angles are complimentary, then the sum of the measures of the angles is 90.

Step-by-step explanation:

A,B,C,D,E all the conditionals have a true converse.

What is converse of a statement?

A conditional statement consists of two parts, a hypothesis in the “if” clause and a conclusion in the “then”

To form the converse of the conditional statement, interchange the hypothesis and the conclusion.

The converse of "If it rains, then they cancel school" is "If they cancel school, then it rains."

Statement If p , then q .

Converse If q , then p .

How to find if converse is true of all the given conditionals?

We have given,

A:If a quadrilateral is a square, then it has four congruent sides.

Let p : A quadrilateral is a square.

q: It has four congruent sides.

Statement p->q

Converse q->p

If it has four congruent sides ,then a quarilateral is a square.

Yes, its converse is also true.

B:If a polygon is a triangle, then it has 3 sides.

Let p : A polygon is a triangle

q:  It has 3 sides.

Statement : p->q

Converse : q->p

If it has three side then polygon is a triangle.

Yes,  its converse is also true.

C: If a quadrilateral is a rectangle, then it has two pairs of parallel sides.

Let p: A quadrilateral is a rectangle

q: It has two pairs of parallel sides

Statement : p->q

Converse : q->p

If it has two pairs of parellel sides then a quadrilateral is a rectangle.

Yes,  its converse is also true.

D:If two angles are congruent, then they have the same measure.

Let p : the angles are congruent

q: two angles have the same measure

Statement : p->q

Converse : q->p

If two angles have the same measure then they are congruent.

Yes, its converse is also true.

E:If two angles are complimentary, then the sum of the measures of the angles is 90.

Let p: Two angles are complimentary

q: The sum of the measures of the angles is 90.

Statement : p->q

Answer:

58 weeks

Step-by-step explanation:

Water tank A = 522 - 4x

Water tank B = 696 - 7x

Where,

x = number of weeks

Equate both equations

522 - 4x = 696 - 7x

Collect like terms

522 - 696 = -7x + 4x

-174 = -3x

Divide both sides by - 3

x = -174/-3

x = 58 weeks

The amount of water in the two tanks will be the same in 58

Answer:

Ace will work 88 problems correctly out of 100.

Step-by-step explanation:

Given that:

Ace worked out 22 problems out of his 25 activities

Ratio = 22:25

If the number of problems are 100, then x be the number of problems correctly solved by Ace.

Ratio = x : 100

The relationship is proportional.

22:25 :: x:100

Product of mean = Product of extreme

25x = 22*100

25x = 2200

[tex]\frac{25x}{25}=\frac{2200}{25}\\x=88[/tex]

Hence,

Ace will work 88 problems correctly out of 100.
