Answer:

2.  200.52    4. 212.67       5. 148.48

Step-by-step explanation:

for (2) you find the area of each shape first the square

12*12=144

then you find the area of the semicircle

the formula is A= (3.14)r^2/2

the (r) is 6 because that is half of the whole side of the semicircle

so... (3.14) 6^2/2

6*6= 36

(3.14)36/2

113.04/2

56.52

then add the 144 from the square to it

56.52+144

200.52

question (4)

-85.5 (area of the triangle)

-127.17 (area of the semicircle)

212.67

question (5)

-48( area of triangle)

-100.48 (area of semicircle)

148.48

Answer:

From 12 o'clock position clockwise:

-12

-1

11

12

Step-by-step explanation:

y = -1 (given).

x + y = 11

Plug in -1 for y in the equation (given):

x + (-1) = 11

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:

x - 1 (+1) = 11 (+1)

x = 11 + 1

x = 12

x + y = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables:

12 + (-1) = 12 - 1 = 11

xy = ?

x = 12

y = -1

Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:

12 * -1 = -12

Answer:

B

X is how much is left, so adding the money spent to that should equal 36.

Answer:

65/100

Step-by-step explanation:

Answer:

You would recieve 66 USD because 22 multipled by 3 is 66.

Answer:

65 + 5x ≥200

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

Janice's savings (65) plus the product of the amount she saves per week (5) and the number of weeks (x) must be higher or equal to $200.

Mathematically speaking:

65 + 5x ≥200

If we solve it for x:

5x ≥200-65

5x ≥135

x ≥ 135/5

x ≥ 27 weeks

Feel free to ask for more if needed or if you did not understand something.

Answer:

6 or possibly 6.0

Step-by-step explanation:

The area of a triangle is equal to the height x base divided by 2, which is basically h × w ÷ 2. So it's 2 × 6 ÷ 2, which equals to 6. If rounded, it should possibly be 6.0.

Step-by-step explanation:

Answer: 23°

Step-by-step explanation:

First, we need to find the missing angle to the left of x

Let's take what we are given

which is 130°, As you notice the angle of 130° is on a straight line

A straight line is supposed to equal 180°

So we can take 180°-130° which will equal 50°

Now we know that the missing angle next to x is 50°

Now we need to take 107° and add it to 50

Which will equal 157°

Now to get x, we need to take 180°-157°

Which will equal 23°

x=23°

Answer:

10

Step-by-step explanation:

Answer:

$17

Step-by-step explanation:

since your finding retail price u need to do 10×.7 and that would be 7 then and the 7 to 10

Step-by-step explanation:

Alright,

Multiply each side by each other so,

16×5 = 80

80×4.5= 360

360× 12 = 4,320

4,320 × 21 = 86,400

The area of this figure is 86,400. I Hope this helps you ^-^ ♡

Answer:

1) x: small #; y: large #

4y = 7x

x + y = 22

----------------

-7x + 4y = 0

x + y = 22

---multiply the second equation by -4------

-7x + 4y = 0

-4x - 4y = -88

----solve------

-11x = -88

x = 8

---substitute with any of the equation above i chose the very first one------

4y = 7(8)

4y = 56

y = 14

x = 8; y = 14

2) x = small #; y = large #

y - x = 15

5x = y - 9

----after rearranging, solve-----

-x + y = 15

5x - y = -9

-4x = 6

x = -1.5

--------substitute--------

-(-1.5) + y = 15

1.5 + y = 15

y = 13.5

x = -1.5; y = 13.5

3) x = lemon cream; y = fudge cookie

3x + 2y = 400

2x + 3y = 425

----multiply the first equation by -2, multiply the second equation by 3------

-6x - 4y = -800

6x + 9y = 1275

----solve------

5y = 475

y = 95

--------substitute--------

3x + 2(95) = 400

3x + 190 = 400

3x = 210

x = 70

x = 70; y = 95

Answer:

1 1/4 or 1.25

Step-by-step explanation:

Answer:

They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.

In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

Answer:

5.

Step-by-step explanation:

On 1 roll of 2 dices probabilty of 12 = 1/6 * 1/6 = 1/36

So the prediction  ffor 180 rolls

= 1/36 * 180

= 5

Answer:

The students in the school are the population. 10 is the sample

The sample is not reasonable, becuase its not even close to half of the school  population

Answer:

23.75

Step-by-step explanation:

Answer:

23.75

Step-by-step explanation:

1. 23.8 - 23.7 = 0.1

2. 0.1 ÷ 2 = 0.05

3. 0.05 + 23.7 = 23.75

this works because to find the middle of two numbers (in this explanation 10 and 20), you have to subtract the larger one from the smaller one (20 - 10 = 10) and take your sum and divide it by two (10 ÷ 2 = 5) and then add it back to the smaller number (5 + 10 = 15 = 1/2 the midpoint of 10 and 20)
