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

Answer:

96 inches

Step-by-step explanation:

Use perimeter to measure the outside edges of something.

(30 × 2) + (18 × 2)

30 + 30 + 18 + 18

96 inches of the ribbon would be needed

In order to determine the inches of ribbon needed, we are to calculate the perimeter of the board

The board is in the shape of a rectangle, so we would use the formula for the perimeter of a rectangle to determine the length of the ribbon needed.

Perimeter of a rectangle = 2 x (length + breadth)

2 x (30 + 18) = 96 inches

Answer:

16

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:

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

converse : q->p

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

Answer:

B

Step-by-step explanation:

Step-by-step explanation:

Volume of Container A

= (8cm)(8cm)(12cm) = 768cm³.

Volume of water = 2/3 * Volume of Container A

= (2/3) * 768cm³ = 512cm³.

Base Area of Container B

= (10cm)(10cm) = 100cm².

Hence Depth of water in Container B

= 512cm³ / 100cm² = 5.12cm.

9^2+x^2=10^2

81+x^2=100

x^2=100-81

x^2=19

square root both sides and you get x=19

Answer:

12 students

Step-by-step explanation:

We know that there are 32 students in a class and 3/8ths of those students bring their own lunches, so we need to find 3/8ths of 32, to find out the number of students that bring their own lunches.

Multiply 3/8 and 32

3/8 ×32

we can reduce each by 8

3×4=12

12 students.

You can double check by doing 12/32, and seeing that it is equal to 3/8
