Answer:

Step-by-step explanation:

For this triangle, since the angle is included between 2 given sides, the formula will be:

[tex]A =\frac{1}{2}ab*ac*sin(angleA)[/tex]

Putting values where they belong:

[tex]A=\frac{1}{2}(10)(12)sin72[/tex]

Do all that in your calculator (in degree mode, NOT radian!) to get

A = 57.1 square cm

Answer:

x = 28

Step-by-step explanation:

given,  x/2 + 49 = 21/4

x/2 + 49 = 9x/4

2x +196 = 9x

7x = 196

x = 28

I hope this helps a little bit.

option B is your correct answer

Answer:

-10y + 11.4

I hope this helps you out

Answer:

-10y+11.4

Step-by-step explanation:

you combine -2y with -8y to get negative -10y. Then you combine 3 and 8.4 to get 11. Variables usually come first in equations, I don't think it matters, but you might want to put them first anyway.

Answer:

y = -2x + 28

Step-by-step explanation:

Slope intercept form is-

y = mx + b

y = y coordinate

m = slope, the rise/run

x = x coordinate

b = the y-intercept, the place the line crosses the y-axis.

Now, fill in the formula with the proper information.

y = -2x + b    You can use the point (10, 8) for the x and y coordinates to find b

  8 = -2(10) + b     Now solve for b

  8 = -20 + b

+20  +20

28 = b                    Now substitute 28 in for b

y = -2x + 28

Answer:

y-8=-2(x-10)

Step-by-step explanation:

y-y1=m(x-x1)

y-8=-2(x-10)

Answer:

x = 1

y = -1

Step-by-step explanation:

-5x + 5y = -10

rewrite the order:

5y = 5x  - 10

6x + 5y = 1

rewrite the order:

5y = 1 - 6x

substitute for 5y:

5x - 10 = 1 - 6x

simplify:

11x = 11

x = 1

5y = 1 - 6(1) = -5

y = -1

Answer:

10 cm

Step-by-step explanation:

[tex]\boxed{area \: of \: traingle = \frac{1}{2} \times base \times height}[/tex]

Substitute known values into the formula:

41.5= ½ ×8.3 ×height

41.5= 4.15 ×height

height

= 41.5 ÷4.15 (÷4.15 on both sides)

= 10cm

Answer:

10 cm.

Step-by-step explanation:

You will first need the formula for finding the Area of a Triangle:

Area = 1/2(Base x Height)

Next, we need our known measurements to plug into the Equation:

41.5 Sq Cm = 1/2(8.3cm x Height)

After that, multiply the equation by 2

2 x 41.5 = (2 x 1/2) x (8.3cm x Height)

∨

83 sq cm = 8.3 cm x Height

Finally, divide your area by 8.3 cm:

83 / 8.3 = 10cm = Height

So, the answer is Height = 10 cm.

Step-by-step explanation:

If you take 12 pieces of pizza and divide it by 4 it equals 3. So 3 times 3 because there are 3 pieces left. Hope that makes sense!

Answer:

radioactive dating of rocks

Answer:

When you reflect a point of the x-axis you can apply:

(x,y) -> (x,-y)

Using this:

(2,-5) -> (2,5)

Since both the x and y places are positive, it is in quadrant 1.

Step-by-step explanation:

Answer:

Option E, two-proportion z test  should be used to determine whether these data provide sufficient evidence to reject the hypothesis that the proportion of shoppers at the suburban mall who had been to a movie in the past month is the same as the proportion of shoppers in the large downtown shopping area who had been to a movie in the past month

Step-by-step explanation:

The complete question is

In a random sample of 60 shoppers chosen from the shoppers at a large suburban mall, 36 indicated that they had been to a movie in the past

month. In an independent random sample of 50 shoppers chosen from the shoppers in a large downtown shopping area, 31 indicated that

they had been to a movie in the past month. What significance test should be used to determine whether these data provide sufficient

evidence to reject the hypothesis that the proportion of shoppers at the suburban mall who had been to a movie in the past month is the same

as the proportion of shoppers in a large downtown shopping area who had been to a movie in the past month?

A one-proportion z interval B two-proportion z interval

B two-proportion z interval

C two-sample t test D one-proportion z test

D one-proportion z test

E two-proportion z test

Solution

Two proportion z test is used to compare two proportions. In this test the null hypothesis is that the two proportions are equal and the alternate hypothesis is that the proportions are not the same. The random sample of populations serve as two proportions.

Hence, option E is the best choice of answer
