Answers

Answer 1

Answer:

X = -4

Step-by-step explanation:

Because both sides are equals, then:

X-3 = 2X-7

What is the slope and y-intercept of the equation y + 8 = 6x Question 6 options: slope: 6; y-intercept: 8 slope: -6; y-intercept: 8 slope: 6; y-intercept: -8 slope: -6; y-intercept: -8

Answers

Answer:

slope: 6; y-intercept: -8

Step-by-step explanation:

The given equation is :

y + 8 = 6x

The general equation of a line is :

y = mx+b...(1)

Where

m is slope and b is y-intercept

Equation (1) can be rewritten as follows :

y = 6x -8

y = 6x +(-8) ....(2)

Compare equation (1) and (2) we get :

Slope, m = 6 and y intercept = -8

Hence, the correct option is (c).

If two angles are supplementary, then they are not congruent. Which diagram provides a counterexample for the statement?
A) A
B) B
C) C
D) D

Answers

Answer:

Step-by-step explanation:

supplmentay angles are either of two angles whose sum is 180°

option b is two right angles (90 degree on both) add them together you get 180.

option c is 60 degrees and 120 degrees add them together to get 180 degrees.

option d is 155 degrees and add 25 degrees you get 180.

so the answer is a, because 30 degrees and add the other 30 degrees together you only get 60

The correct answer is A, because 30 degrees and add the other 30 degrees together you only get 60.

What are supplementary angles?

The supplementary angles are defined as the angles whose sum is equal to 180°.

Supplementary angles are either of two angles whose sum is 180°

Option b is two right angles (90 degrees on both) add them together you get 180.

Option c is 60 degrees and 120 degrees add them together to get 180 degrees.

Option d is 155 degrees and add 25 degrees you get 180.

Therefore, the answer is A, because 30 degrees and adding the other 30 degrees together you only get 60.

Answer:

6 weeks

Step-by-step explanation:

From the question:

Let us represent the number of weeks as x

Andre and Alina are each saving money.

For Andre:

Andre starts with $100 in a savings account and adds five dollars per week

$100 + $5 × x

= 100 + 5x

For Elena

Elena starts with $10 in her savings account and add $20 each week

$10 + $20 ×x

= 10 + 20x

The next step is to equate both algebraic expression for Andre and Elena together

Hence:

100 + 5x = 10 + 20x

Collect like terms

100 - 10 = 20x - 5x

90 = 15x

x = 90/15

x = 6 weeks

Hence, after 6 weeks Andre and Elena would have the same amount of money in their savings account.

D.a rotation of 180° followed by a reflection about the line x = 3
Can you also explain please?

Answers

Answer:

B. a reflection about the x-axis followed by a translation

Step-by-step explanation:

A reflection over the x-axis, since it is horizontally flipped and has the corresponding coordinates that involve the numbers 1 and 3 (based of the points on (-3,1) and (3,-1).

And it is translated to the right, because it was not rotated at all and is on the right side or 4th quadrant. If it was not translated, the reflection would be below triangle1 with the point on (-3,-1), but the point is instead moved 6 units to the right to be on (3,-1).

Marco has a $15.00 gift card to a movie theater. He wants to buy each of his friends a $3
candy bar. The function f(x)=3x-15 represents the amount of cash needed to purchase x candy
bars after using his gift card. He brings 7 friends. How much of his own money does he need
to spend to buy all 7 friends a candy bar?

Answers

Answer:

I believe the answer is 6

Step-by-step explanation:

f(x) = 3x - 15 -- plug 7 into x (that's how many candy bars he's buying)

f(x) = 3(7) - 15 -- solve the equation (just know that 3(7) is the total, and 15 is the amount of money on his gift card.)

f(x) = 21 - 15

f(x) = 6 -- your answer

Write the number sentence that fits this: "Daniel found 17 basketballs but 3 of
them were broken and another 5 needed pumping. There were only 9
basketballs that could be used.’’

Answers

Answer:

17-3-5=9???

Step-by-step explanation:

The number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

"Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.’’

Let x be the total number of basketballs that can be used.

x = 17 - 3(broken) - 5(need to pump)

x = 17 - 3 - 5

x = 17 - 8

x = 9

9 = 17 - 3 - 5

Thus, the number expression is 9 = 17 - 3 - 5 if Daniel found 17 basketballs but 3 of them were broken and another 5 needed pumping. There were only 9 basketballs that could be used.

It is given that p varies inversely as q. If p = 12 and q = 45 find p, if q is 135.

Answers

Answer:

[tex]p =4[/tex]

Step-by-step explanation:

Given

Variation: Inversely

[tex]p = 12[/tex] when [tex]q = 45[/tex]

Required

Determine p when [tex]q = 135[/tex]

First, we need to determine the relationship between p and q

Since, it is an inverse variation.

The relationship is:

[tex]p\ \alpha\ \frac{1}{q}[/tex]

Convert to an equation

[tex]p= k *\frac{1}{q}[/tex]

[tex]p= \frac{k}{q}[/tex]

Where k = constant of variation

Make k the subject

[tex]k = p * q[/tex]

When [tex]p = 12[/tex] and [tex]q = 45[/tex]

[tex]k = 12 * 45[/tex]

[tex]k = 540[/tex]

To solve for p when q = 135

Substitute 135 for q and 540 for k in [tex]p= \frac{k}{q}[/tex]

[tex]p = \frac{540}{135}[/tex]

[tex]p =4[/tex]

Mrs. Cervantes wants to paint her windmill. It has six sides, each of which is 3.5 feet wide by 11 feet tall. How many square feet does she need to paint?

Answers

Answer:

231 ft²

Step-by-step explanation:

Given that :

Dimension of each side = 3.5 feets by 11 feets

Area of each side :

Length * width = (3.5 * 11) feets = 38.5 ft²

Number of sides = 6

Hence, number of square feets to paint :

Number of sides * area of each side :

6 * 38.5 ft²

= 231 ft²

Tennis balls with a diameter of 2.5 inches are sold in cans of three. The can is a cylinder. What is the volume of the space NOT occupied by the tennis balls? (Assume the tennis balls touch the can on all sides, top and bottom.) Round to the nearest tenth and show all steps and reasoning.

Answers

Answer:

The space NOT occupied by the tennis balls is 12.26 cube inches.

Step-by-step explanation:

The space NOT occupied = volume of cylinder - total volume of spheres

The can is cylinder with volume = [tex]\pi[/tex][tex]r^{2}[/tex]h

where r is the radius and h the height of the cylinder

With the given condition,

r = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{2.5}{2}[/tex]

= 1.25 inches

h = 3 x diameter = 3 x 2.5

= 7.5 inches

So that,

Volume of the can = [tex]\frac{22}{7}[/tex] x [tex](1.25)^{2}[/tex] x 7.5

= 36.830

Volume of can is 36.83 cube inches.

The tennis ball is a sphere with volume = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](1.25)^{3}[/tex]

= 8.185

Volume of the tennis ball is 8.19 cube inches.

Since they are sold in three's, then;

total volume of the tennis balls = 3 x 8.19

= 24.57

Volume of the tennis balls is 24.57 cube inches.

Thus,

The space NOT occupied = 36.83 - 24.57

= 12.26

The space NOT occupied by the tennis balls is 12.26 cube inches.
