Answer: 8.4 meters

Step-by-step explanation:

From the question, we are informed that a roll of ribbon was 12 meters long and that Diego cut 9 pieces of ribbon that were 0.4 meter each to tie some presents. The length of ribbon used by Diego for the present would be:

= 9 × 0.4meter

= 3.6 meter.

Therefore, the meters of ribbon that were available for making wreaths would be:

= 12 meters - 3.6 meters

= 8.4 meters

Answer:

5.4

Step-by-step explanation:

We have 12 meters total,Diego: 9 pieces × 0.4 meters= 3.6 meters

So Diego used up 3.6 meters of ribbon

Part A: 9-3.6=5.4 meters left

Given:

A biased dice is thrown 300 times.

Table of probabilities of each score.

To find:

The expected number of times the score will be odd.

Solution:

Odd numbers on the dice are 1, 3, 5. The sum of their probability is

[tex]0.15+0.25+0.3=0.7[/tex]

Even numbers on the dice are 2, 4, 6. The sum of their probability is

[tex]0.05+0.05+0.2=0.3[/tex]

Now, the expected number of times the score will be odd is

[tex]\text{Expected odd number}=300\times \text{Probability of getting an odd number}[/tex]

[tex]\text{Expected odd number}=300\times 0.7[/tex]

[tex]\text{Expected odd number}=210[/tex]

Therefore, the expected number of times the score will be odd is 210.

Answer:

D

Step-by-step explanation:

Angle 5 is equal to angle 8 because the two angles are an alternate interior angle. We already know that angle 7 and 8 are supplementary because it's adjacent to each other on a straight line. So, since angle 5 and 8 is equal to each other, angle 5 is also supplementary to angle 7.

Answer:

Q10: 5x - 3

Q15: s = 2

Q21: 4 ft

Q24: -33%

Q42: 10.3

Step-by-step explanation:

Question 10) Simplify. 5 + 2(3x − 4) − x

5 + 6x - 8 - x

= -3 + 5x

= 5x -3

Question 15) Solve. 27s − 29 = 54s − 83.

27 s -27 s -29 + 83 = 54 s -27 s -83 + 83

54 = 27 s

s = 2

Question 21) On a sunny day, a 2-foot red kangaroo casts a shadow that is 7 feet long. The shadow of a nearby eucalyptus tree is 14 feet long. Find the height of the tree.

The ratio of the tree and kangaroo is 2:1

Therefore, using this logic, 14 / 7 = 2, 2 x 2 = 4ft

The height of the tree is 4ft

Question 24) Find the percent change from 600 to 408. Tell whether it is a percent increase or decrease. If necessary, round your answer to the nearest percent.

408 / 608 = 0.67 = 67%

67 - 100 = -33%

This is a percent decrease

Question 42) Use the distance formula to find the distance to the nearest tenth, from R(7, −2) to W(−2, 3).

Distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

d = sqrt((-2 - 7)^2 + ( 3 - (-2))^2

d = sqrt((-9)^2 + (5)^2)

d = sqrt(81 + 25)

d = sqrt(106)

d = 10.29 = 10.3 (nearest tenth)

Answer:

The point (4,3) is not the solution of y ≤ -2x -5

Step-by-step explanation:

We need to tell whether (4, 3) is a solution of y ≤ -2x -5

To check if (4,3) is solution of y ≤ -2x-5 we will put the values of x and y and check if the inequality hold true or not.

Now put x = 4 and y = 3

y ≤ -2x -5

3 ≤ -2(4) -5

3 ≤ -8-5

3 ≤ -13 (False)

As 3 is not less than -13 so, inequality doesn't hold true.

Therefore the point (4,3) is not the solution of y ≤ -2x -5

Awnser:

61 ft

Step-by-step explanation:

To find the perimeter add all the lengths of the sides together. The perimeter is just the length around the outside of the shape.

6.2 + 16.6 + 6.2 + 15 + 17 = 61ft

Answer:

14.5*29=420.5 miles for a full 14.5-gallon tank.

7.25-gallons is what is left in a half tank.

105.125 miles can be driven on a quarter tank.

if the low milage alert comes on at 50 miles left they have 1/9 of the tank left with gas.

if the low milage alert comes on at 50 miles left he was 1.724 gallons of gas left.

It would cost $30.28 to get the tank back to a full 14.5 gallons.

Step-by-step explanation:

It was mostly basics knowing that 29 miles per gallon and then its just plug in til it fits.

Answer:

Step-by-step explanation:

Corresponding angles of both the squares are congruent. (angles of a square measure 90°)

Ratio of the sides of the given squares = [tex]\frac{\text{Side length of small square}}{\text{Side length of the large square}}[/tex]

                                                                 = [tex]\frac{2}{5}[/tex]

This ratio of side lengths is constant for all corresponding sides.

Therefore, corresponding sides are proportional.

Since, all angles of both the squares are congruent and all the sides are proportional, both the squares will be similar.

Scale factor = [tex]\frac{\text{Side length of large square}}{\text{Side length of the smaller square}}[/tex]

                    = [tex]\frac{5}{2}[/tex]

                    = 2.5

This sequence of similarity transformations shows the figures are similar.

Answer:

m= -12

Step-by-step explanation:

-15m-30=-12m+6

-3m=36

m=-12

Answer:

m = -12

Step-by-step explanation:

Simplify the Left Hand Side:

[tex]-5\left(3m+6\right) = -5\cdot \:3m+\left(-5\right)\cdot \:6[/tex]

[tex]=-15m-30[/tex]

Simplify the Right Hand Side:

[tex]-3\left(4m-2\right)=-3\cdot \:4m-\left(-3\right)\cdot \:2[/tex]

[tex]=-3\cdot \:4m+3\cdot \:2[/tex]

[tex]= -12m+6[/tex]

All together we have:

[tex]-15m-30=-12m+6[/tex]

Add 30 to both sides and simplify:

[tex]-15m-30+30=-12m+6+30[/tex]

[tex]-15m=-12m+36[/tex]

Add 12m to both sides and simplify:

[tex]-15m+12m=-12m+36+12m[/tex]

[tex]-3m=36[/tex]

Finally, we divide both sides by -3:

[tex]\frac{-3m}{-3}=\frac{36}{-3}[/tex]

And we get the answer

m = -12

Answer:

x=8

Step-by-step explanation:

We move all terms to the left:

3x+4-4-(2x+8)=0

We add all the numbers together, and all the variables

3x-(2x+8)=0

We get rid of parentheses

3x-2x-8=0

We add all the numbers together, and all the variables

x-8=0

We move all terms containing x to the left, all other terms to the right

x=8

Answer:

your answer is

3+4−4=2+8

3=2+8

Subtract

2from both sides of the equation

then you Simplify and you get =8
