(11.01 MC)
Michelle has a piece of yarn measuring 7 yards. How many 1-inch strips can be cut from the yarn?
0252 strips
O 216 strips
180 strips
O 144 strips

Answer:

50º

Step-by-step explanation:

A triangles angles = 180º

Angle A = 40º

Angle C = 90º  (this is a right triangle)

40º + 90º = 130º

180º - 130 º = 50º

Answer:

A.

Step-by-step explanation:

The figure is made up of a rectangle and two triangles.

The dimensions of the 3 polygons are:

Rectangle: 8 m by 15 m

Triangle 1: 15 m base and 7 m height

Triangle 2: 9 m base and 8 m height

Total area =

= [8(15) + 15(7)/2 + 9(8)/2] m^2

Answer: A.

Answer:

80

Step-by-step explanation:

48:60*100 =

(48*100):60 =

4800:60 = 80

Answer:

48 is 80 percent of 60

Answer:

The answer is 1. f(a) = –2a^2 – 5a + 4. If a = -3, then to find f(-3) we have to substitute a in the general formula. f(a) = –2a^2 – 5a + 4 = -2 * a^2 – 5 * a + 4. Substitute a with -3. f(-3) = –2 * (-3)^2 – 5 * (-3) + 4 = -2 * 9 - (-15) + 4 = -18 + 15 + 4 = 1

Step-by-step explanation:

Answer:

y=2x-5

y=1/2x-2

2x-5=1/2x-2

3/2x-5=-2

3/2x=3

x=2

y=2(2)-5

y=4-5

y=-1

So, the answer is (2, -1)

Yep, you're correct.

Let me know if this helps!

Step-by-step explanation:

Take the inverse function of the trig functions and plug the number in your calculator.

Answer: two times

Step-by-step explanation:

Given

height of cone A and B  [tex]h_a=h_b=5\ in.[/tex]

The volume of cone A  [tex]V_a=20.9\ in.^3[/tex]

The volume of cone B is 4 times of cone A

the volume of a cone is  [tex]\frac{1}{3}\pi r^2h[/tex]

The volume of cone A

[tex]V_a=\dfrac{1}{3}\pi r_a^2h_a=20.9\quad \ldots(i)[/tex]

The volume of cone B

[tex]V_b=\dfrac{1}{3}\pi r_b^2h_b=4\times 20.9\quad \ldots(ii)[/tex]

divide (i) and (ii) we get

[tex]\Rightarrow \dfrac{r_a^2}{r_b^2}=\dfrac{1}{4}\\\Rightarrow \dfrac{r_a}{r_b}=\sqrt{\dfrac{1}{4}}=\dfrac{1}{2}\\\Rightarrow \dfrac{d_a}{d_b}=\dfrac{1}{2}\\\Rightarrow d_b=2d_a[/tex]

thus, diameter of cone B is twice the diameter of A

Answer:

7/10

Step-by-step explanation:

Hey There!

there are a total of 10 balls and only 3 out of the ten are pink

so the probability of them picking a pink one is 3/10 and the probability of them not picking a pink one is 7/10

Answer:

18

Step-by-step explanation:

Let the unknown number be = x

Then,

x + 16 = 34

=> x = 34 - 16

=> x = 18 (Ans)

Answer:

B

Step-by-step explanation:

-5(2x-4y)

-5*2x = -10y

-5*-4y = 20y

So, -10x+20y

Answer:

10^-9

Step-by-step explanation:

Answer: 12.57 ft

Step-by-step explanation:

Circumference of circle with radius of 4ft.

= π * radius * 2

= 22/7 * 4 * 2

= 25.14 ft

Circumference of circle with radius of 6ft.

= 22/7 * 6 * 2

= 37.71 ft

Difference = 37.71 - 25.14

= 12.57 ft

Answer:

y= -7

Step-by-step explanation:

There's no need to include x as the y-value will always be -7, but if your question requires it then you could say something like y=(x-x)-7

Answer:

The answer above is wrong, the line is actually supposed to be one to the left, so it would be going through (7,4) and (2,-2)

Step-by-step explanation:

Answer:6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

jimmy had 4x2/3 tacos he didnt know how many he had so he asked his mom and jimmys mom said that he had to do the math and when he figured out the answer he got  2/3 x 4 = 8/3 in fraction form. 2/3 x 4 = 2.6667 in decimal form. and his mom was proud of him

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.
