Answer 2

Answer: 96 units

Step-by-step explanation:

3 by 4 Right Triangles: [tex](3*4)/2[/tex] for each triangle, so [tex]2((3*4)/2)=12[/tex]  units for both two triangles.

Middle Rectangles: Since all of the 3 rectangles have the same height, we can add together the widths to get [tex](3+4+5)*7=12*7=84[/tex] units.

Add them together: [tex]84+12=96[/tex] units

I hope it helps!

Explain how to prove that an image is the dilation of a preimage in the coordinate plane.

Answers

Answer:

Look at the longest side of the original figure and then look at the longest side of the new figure.

Step-by-step explanation:

Say the dilation was by 1/2, if the longest side on the original figure is 6, the longest side on the new figure should be 3. Or if the dilation was 4, if the longest side of the original figure is 3, the longest side of the new figure should be 12. After doing that, check all of the other sides with the dilation in mind and check if it adds up.

Mel paid for 3/4 of the cost of a cake and Gretchen paid the rest if Mel paid $21 how much did Gretchen pay

Please show how u got it

Answers

21 / 3 = 7, Gretchen paid $7
The cake cost $28 in total
$21 is 3/4 of $28, because 28 divided by 4 is 7. 7 times 3 is 21. $28 minus $21 is $7. Mel paid $21, and Gretchen paid $7 for the cake. To find the answer, first divide the cost of the cake as a whole by the denominator (bottom or right-side number) of your fraction. Now, take the quotient and multiply it by your numerator (top or left-hand number of your fraction). Subtract your answer from the total cost of the cake, and you’ll see how much was paid. Hopefully this helps!

Answers

Answer:

C.

Step-by-step:

We know that:

a bus travels 6 hours at a constant speed of 36 mph.

What we don't know:

How FAR the bus traveled.

So, we solve by using t * mph = mi:

36 * 6= 6 * 6= 366 * 30= 18036 + 180= 216The bus traveled 216 mi.

5.  s ÷ 10, 8b, h + 7, 3r - 8

6. 248

Step-by-step explanation:

5.s divided by 10 would be written as s ÷ 10. 8 times b would be written 8b or 8 x b. 7 more than h would be written h + 7 because you are doing 7 more that h not h more than 7. 8 less than the product of 3 and r is written 3r -8 because the word product means to multiply. So, the question is 8 less than 3 times r which is written 3r -8 or (3 x r) - 8.

6. is 248 because if you drive 62 miles each hour and you drive for four hours you will go 248 miles in total. You just multiply 62 times 4.

Answer: 6 more games

Step-by-step explanation:

Let’s review what we know:

The red team’s probability of winning is 70% (0.7).The blue team’s probability of winning is 65% (0.65).There are a total of 120 games.


To find the amount of games each team will statistically win, we multiply the percentage by the number of games.


Red Team: 0.7 x 120 = 84 games.

Blue Team: 0.65 x 120 = 78 games.


84 - 78 = 6 games.
Therefore, the red team will statically win 6 more games than the blue team.

Answer:

  66°

Step-by-step explanation:

The applicable angle relations are ...

An exterior angle of a triangle is equal to the sum of the remote interior angles. Vertical angles are congruent.

__

We recognize that angle HIJ, marked 105°, is an exterior angle to triangle DIJ. We also recognize that the angle marked x° is a vertical angle to angle DJI in triangle DIJ. Angles JDI, marked 39°, and DJI are remote interior angles with respect to angle HIJ.

We can use the relations described above to say that ...

  ∠HIJ = 39° +∠DJI

  39° +x° = 105°

  x° = 66° . . . . . . . subtract 39°

The measure of angle x is 66°.

the answer would be 66 degrees

A student took 5 test in a quarter 3. His average was a 88. Four of his test scores were 87, 94, 86, and 100. What was his last test score? ( statistics) ( please write down or type it out! ) ty

Answers

Answer:

The last test score should be 73

Step-by-step explanation:

[tex]88 = \frac{( 87 + 94 + 86 + 100 + X )}{5}[/tex]  

Add all the values in the parentheses together to get:

[tex]88 = \frac{367 + X}{5}[/tex]

You want to remove the 5 next, so you multiply both sides by 5.

[tex]5 * 88 = \frac{367 + x}{5} *5[/tex]

[tex]88 * 5 = 440[/tex]

You should get:

[tex]440 = 367 + x[/tex]

The last step is to subtract both sides by 367:

[tex]440 - 367 = 73[/tex]

[tex]X = 73[/tex]

I hope this helps!

I'll give 100 points Devon and his friends bought strawberry wafers for $3 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $30 to buy a total of 22 packets of wafers of the two varieties.


Part A: Write a system of equations that can be solved to find the number of packets of strawberry wafers and the number of packets of chocolate wafers that Devon and his friends bought at the carnival. Define the variables used in the equations.


Part B: How many packets of chocolate wafers and strawberry wafers did they buy? Explain how you got the answer and why you selected a particular method to get the answer.

Answers

[Part A]

   A system of equations is different equations that can be used to find different variables. We will write one for the money spent and one for the items bought. Let x be strawberry wafers and y be chocolate wafers.

   $3x + $1y = $30

   x + y = 22

[Part B]

   We will graph the two systems to solve. I am choosing this method because it is the quickest and easiest.

   The point of intersection is the solution. Remember x is strawberry and y is chocolate. They bought 4 strawberry and 18 chocolate.
