then subtracted

Answer:

A) 24 - 3p

Step-by-step explanation:

Distribute 6 through parenthesis

24 - 12p + 9p

then collect like terms

24 - 3p

Answer:

(C) 66.63 sq in.

Step-by-step explanation:

The composite shape is a trapezoid + semi circle

The formula for area of a trapezoid is:

1/2(b1+b2)h

Where b1 is base 1

Where b2 is base 2

Where h is height

B1 is 6

B2 is 9

h is 7

1/2 (6 + 9) 7

1/2 (15) 7

7.5 x 7

= 52.5

The Semi circle formula is:

pi x r^2 (all divided by 2)

Where pi is 3.14

Where r is radius

The radius is 1/2 the diameter

6/2 = 3

3.14 x 3^2 /2

3.14 x 9 / 2

28.26 / 2

= 14.13

Trapezoid + Semi Circle

52.5 + 14.13

= 66.63 sq in.

Answer:

The correct answer is A.

Step-by-step explanation:

Given that a weather researcher compared Dublin, Ireland to Madrid, Spain, and she found that Dublin had a mean average temperature of 56.1ºF with a mean average deviation of 6.4ºF, while Madrid had a mean average temperature of 68ºF with a mean average deviation of 12.1ºF, the following conclusions can be drawn:

68 is higher than 56.1, so clearly Madrid has a higher average temperature than Dublin.

In turn, 12.1 is greater than 6.4, with which Madrid has a greater temperature variation than Dublin.

i would help but i can't see the picture

Answer:

Step-by-step explanation:

Maybe it's counting up by tens

Bank: 0, 10, 20, 30, 40, 50

Spend: 10, 20, 30, 40, 50

Give me a second I will make and edit I need to actually think for this lol

Also nice prof pic ;)

Answer:

11

Step-by-step explanation:

x+y=8     y=3

x+3=8

-3     -3

x=11

Answer:

substitute y in the equation

x+3=8

then we solve for x

transpose 3 to the right 8-3=5so therefore x=5

The pair of corresponding sides of triangles are,

⇒ MN and RQ

Option B is true.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Triangle LMN,

Side LM is 7, MN is 5, and LN is 4.

And, Triangle PQR,

Side PQ is 8.8, QR is 11, RP is 15.4.

Here, Two triangles are similar.

Hence, The pair of corresponding sides of triangles are,

⇒ MN and RQ

Option B is true.

Answer:

answer is D.

Step-by-step explanation:

divide 2550 and 3.2 and get 796.875. multiply that by 3 and you get 2390.625.

Answer:

Option C 2794.8

Step-by-step explanation:

I'm not sure if it is correct but this is what I do

To find the total amount in the account you first need to find how much the interest rate is worth.

To find that you do 2550 times the interest rate which is 3.2 and you get 8160. Then you divide that by 100 which is 81.6

81.6 is the interest rate you get in one year. You multiply this by three and you get 244.8 which is the interest rate for three years.

Know add the interest rate to the amount of money deposited and you get your answer 2794.8

Answer:

#2 : C

#4 : C

Step-by-step explanation:

Question 2:

Pyramids with the same base & height will always be 1/3 the volume of a prism with the same base & height.

Question 4:

Equation for volume of a pyramid: lwh/3

The length, width, and height of the pyramid all equal 4.5 inches

volume = (4.5*4.5*4.5)/3

volume = 91.125/3

volume = 30.375 or 30 and 3/8

Answer:

Kinetic energy is present.

Step-by-step explanation:

It's present by the moving winds in the storm, and by the winds moving things such as trees, branches, or plants.

Answer:

-3/2

Step-by-step explanation:

Remeber, to find slope we use this formula:

y - y all over x - x, or (y-y) / (x-x)

(6-9) / (5-3)

-3 / 2

= -3/2

Answer:

-12x-4

Step-by-step explanation:

2(-7x+(x-2)) =

-14x+2(x-2) =

-14x+2x-4 =

-12x-4

[tex]-x^2-2[/tex]

Because [tex]-x^2[/tex] is [tex]x^{2}[/tex] flipped over.

Then you need to -2.

Answer:

A

Step-by-step explanation:

I used a graphing calculator  and just put in the options and found which one was g(x).

Answer:

112 Miles

Step-by-step explanation:

16 (per hour)  for 7 hours

16x7 (we Multiple the speed [since its per hour] the number of hours.)

112

Given:

Speed of Juan = 16 mph

Time traveled = 7 hours

To find:

Total distance traveled

Steps:

Total distance traveled is equal to speed into time traveled,

Total distance = Speed × time traveled

Total distance = 16 × 7

Total distance = 112 miles

Therefore Juan traveled 112 miles in 7 hours at the speed of 16 mph

Answer:

A: y=1/3x+5

B: y=-2x+9

C: y=-3

D:y=2x+9

E: y=-10x+80

F:y=x-2

#1 rodney's error for

y=30x+10 is that he started off at 30 but he had to start off at 10 so it starts at (0,10) (1,40) (2,70) and keep going on by adding one to the x value and 30 to the y value

#2 rodneys error for

y=-1/2x+5 is that he went up by 1/2 instead of going down. it's a negative 1/2 so he had to go down

#3 Rodneys error for

y=x-2 is that he didn't start at (0.-2)

like i said, bxh 2.5x1.8=4.5. Do u need help with anything else?

Answer:

Step-by-step explanation:

Area of a parallelogram is the base times its height

A=2.5(1.8)

A=4.5 m^2

Answer:

$175

Step-by-step explanation:

10% of 500 you know is 50

so if you add 10% 3 times you know that that's 30% and its easy to add.

50+50+50= $150

than you add the 5% and how you get 5% if you split the 10% in half. Half of 50 is 25 so therefor if you add 10+10+10+5= 35% and if you add 50+50+50+25= $175

Answer:

1) D.208

2) C.112

Step-by-step explanation:

so basically for 1 you solve the area for all the shapes you see in the net using the equation l*w=a and add them together

l= length

w=width

a=area

4*8=32

4*8=32

6*4=24

6*4=24

6*8=48

6*8=48

48+48+24+24+32+32=208

208[tex]cm^{2}[/tex]

for number 2 since it's lateral surface area, you wanna find the area of all the shape in the net except for the square in the middle.

for the triangles you're gonna wanna use the equation 1/2b*h=a

b= base

h=height

a=area

7*4=28

7*4=28

7*4=28

7*4=28

28*4=112
