The seventh grade class is raising money to have a class trip at the end of the year. They began the year with $1500. They now have $1650 in the account. What is the percent of increase for the money the class has raised ?

Answer:

11/20

Step-by-step explanation:

[tex]55\% = \frac{55}{100} = \frac{11}{20} [/tex]

Answer:

43.9°

Step-by-step explanation:

We solve the above question using the Trigonometric function of Cosine

cos x = Adjacent/Hypotenuse

From the question

Adjacent = Distance of the boat from the dock = 18 feet

Hypotenuse = Length of the rope = 25 feet

The angle formed by the rope and the surface of the water = x

Hence:

cos x = 18/25

x = arc cos (18/25)

x = 43.945519562°

Approximately θ = 43.9°

The angle formed by the rope and the surface of the water is given as 43.9°

Answer:

m<1 = 97

m<2 = 83

m<3 = 112

m<4 = 68

m<5 = 112

m<6 = 68

m<7 = 97

m<8 = 83

m<9 = 97

m<10 = 83

m<11 = 112

m<12 = 68

m<13 = 112

m<14 = 68

m<15 = 97

m<16 =  83

Answer:

[tex]56[/tex] cents

Step-by-step explanation:

If [tex]18[/tex] inches of wire cost [tex]72[/tex] cents, then each inch of wire will cost [tex]\frac{72}{18}=4[/tex] cents. Therefore, 14 inches of wire will cost [tex]14*4=56[/tex] cents. Hope this helps!

Answer:

56 cents

Step-by-step explanation: 72 cents divided by 18= 4 so for one inch of wire it cost 4 cents       Then 14 inches times 4= 56  I think thats

Answer:

d.24

Step-by-step explanation:

12*2=24 and a negative times a negative always equals a positive.

Answer:

∠ 1 = 110°, ∠ 2 = 70°

Step-by-step explanation:

∠ 1 and 110° are vertical angles and are congruent, thus

∠ 1 = 110°

∠ 1 and ∠ 2 are same- side interior angles and supplementary, sum to 180°

∠ 1 + ∠ 2 = 180°

110° + ∠ 2 = 180° ( subtract 110° from both sides )

∠ 2 = 70°

Answer:

5 units to the right!

It would take 3 unites to the right to get the 0 and then 2 more units to the right to get to 2, so that means 5 units in total to the right.

Answer:what is this

Step-by-step explanation:

Answer:

640 is the Answer

Step-by-step explanation:

Answer:

1360 square inches

Step-by-step explanation:

So to find area, you do bh

b is base

h is height

The base the of the rectangle going vertical in the plus sign is first.

The base is 20 and the height is 44

20 times 44 yields 880

then the two rectangles on either side of the bigger rectangle.

20 is the height, 12 is the base.

20 times 12 yields 240

there are two of those rectangles so

240 times 2 yields 480

480 plus 880 yields 1360

Step-by-step explanation:

6 =$3

Answer: 36

Step-by-step explanation:

From the question, we are informed that for every 4 silver cars that are sold, 6 red cards are also sold.

When there are 90 cars sold in a month, the number of silver cars that were sold would be:

= [4 / (4 + 6)] × 90

= 4/10 × 90

= 4 × 9

= 36 silver cars

Answer:

$21.97

Step-by-step explanation:

2(5.99)+ 1(9.99) = 11.98 + 9.99 = 21.97

Answer:

-3 and 17

Step-by-step explanation:

Let the number be = x

x - 7 = -10

x = -10 + 7

x = -3

OR

7 - x = -10

- x = -10 - 7

- x = -17

x = -17/-1

x = 17

The two possible numbers are -3 and 17

Answer:

C

Step-by-step explanation:

Since it is only addition and subtraction, you can rearrange the order of the equations. This is what the three eqautions will look like after the arrangement:

1.6z + 8.3 z = ? (9.9z)

6.2y - 5.1y = ? (1.1y)

4.3x + 5.5x = ? (9.8x)

Then you just add and subtract.

Step-by-step explanation:

-143 = -11x : Original problem

[tex]\frac{-143}{-11}[/tex] = [tex]\frac{-11x}{-11}[/tex] : Isolating the variable

13 = x : Simplification  (Note: when you divide a negative number by a negative number, the answer is positive)

Answer: x=13

Answer:

Regular peanut butter - .23

Family Size Peanut Butter - .15

Answer:

#1: 0.23

#2: 0.15

Step-by-step explanation:

1.38/ 6= 0.23

0.15*52= 7.80

Answer:

12

Step-by-step explanation:

Answer: 10

Step-by-step explanation: Each side if the smaller shape is  multiplied by 1.5 to get the dimensions of the larger shape. To find the value of x, you divide 12 by 1.5. Then you add 2 to that answer to get the value of x.  [tex]12/1.5 = 8 + 2 = 10[/tex]

Step-by-step explanation:

Mary spends 8*6=48 dollars

Pete spends 9*12=108

Mary got a better deal per cupcake

Answer:

They spent the same amount per cupcake ($1.33)

Step-by-step explanation:

To solve this, we need to find the unit rate of cost per cupcake. To do that, we divide 8 by 6 and divide 12 by 9. When we do that, we get 1.33 for both. That means they spent the same amount per cupcake ($1.33).

Answer:b

Step-by-step explanation:

Answer:

x = 14

Step-by-step explanation:

Cross multiply.

7 x 4 = 28.

X x 2 = 2x

2x = 28

x = 14

Answer:

3

Step-by-step explanation:

Given that:

Integers : x, x + 1, x + 2

6x - 2(x + 1) = (x+2) + 5

6x - 2x - 2 = x + 2 + 5

4x - 2 = x + 7

4x - x = 7 + 2

3x = 9

x = 9/3

x = 3

First integer = x = 3

2nd integer = x + 1 = 3+1 = 4

3rd Integer = x + 1 + 1 = 3 + 2 = 5
