Answer:pretty sure its 10 degrees

Step-by-step explanation:

all tris add up to 180, and this one is a right angle so you know you have 90 deg, 80 degrees. 90+80=170; 180-170=10

Answer:

151

Step-by-step explanation:

180 - 29

Answer:

B) 61

Step-by-step explanation:

When angles are complementary, that just means they add up to 90 so:

90 - 29 = 61

Answer:Amount of white  paint used by Sarah =1.82 pints

Step-by-step explanation:

Amount of  blue paint and white paint to paint her bedroom walls.=9.1 pints

Amount of  blue paint used =4/5 x 9.1=7.28 pints

Amount of white  paint used=Amount of  blue paint and white paint to paint her bedroom walls -Amount of  blue paint used

=9.1-7.28=1.82 pints

Answer:

1 triangle can be formed

We are given three side lengths, which are 17cm, 23cm, and 13cm. So, we can form the triangle when;

17 + 23 > 13

17 + 13 > 23

23 + 13 > 17

Since the above conditions are met, then we can form one triangle.

Now, each next triangle with the same sides lengths will be congruent to the first triangle by SSS postulate.

SSS postulate states that: If the three sides of a triangle are congruent to the three sides of another triangle, then the two triangles are congruent.

Thus, only 1 triangle can be formed.

Complete question is;

The city just assigned a second garbage truck to empty the bins in Kat’s neighborhood on trash day. The crew from the first garbage truck used to empty all the bins by themselves in 5 hours. In their training, it took the crew from the second garbage truck 8 hours to empty all the bins. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? To the nearest tenth, the first garbage truck will empty about of all the bins.

Answer:

Part of all bins first garbage truck will empty = 0.6

Step-by-step explanation:

Let the total number of bins emptied be denoted by n.

We are told that the crew from the first garbage truck empties all the bins in 5 hours. Thus

Work rate = (n/5) bins/hr

We are told the second garbage truck empties in 8 hours. Thus;

Work rate = (n/8) bins/hr

When both garbage trucks work together, the total amount of time spent will be denoted by x. Thus;

((n/5) + (n/8))x = n

Divide through by n to get;

x/5 + x/8 = 1

Multiply through by 40 to gwt;

8x + 5x = 40

13x = 40

x = 40/13 hrs

To find the part of all the garbage bins the first garbage truck empty when they work together, we will simply multiply the value of x by the work rate of the first garbage truck. Thus;

Part = (n/5) × (40/13)

Part = (40/65)n = 0.615 of n

To the nearest tenth gives 0.6 of n

Answer:

1.5 pounds. it's simply 3/8 times 4

Answer:

1.5 pounds of chocolate

Step-by-step explanation:

A single batch of ice cream takes [tex]\frac{3}{8}[/tex] of a pound of chocolate. For every added batch, we add another [tex]\frac{3}{8}[/tex] pound, or multiply [tex]\frac{3}{8}[/tex] by the number of batches.

In this case, we are making 4 batches, so we need to multiply [tex]\frac{3}{8}[/tex] by 4.

[tex]4\cdot \frac{3}{8}[/tex]

[tex]\frac{4}{1}\cdot \frac{3}{8} =\frac{3}{2}[/tex]

[tex]\frac{3}{2}=1.5[/tex]

We need 1.5 pounds of  chocolate to make 4 batches of ice cream.

Good luck ^^

Answer:

B or (8π + 12) in.2

Step-by-step explanation:

The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].

The composite figure is made up of a semicircle and an isosceles triangle.

The area of a semicircle = (1/2)π[tex]r^{2}[/tex]

radius =  4 inch

When we substitute, the area of the semicircle is

= (1/2)π[tex]\times[/tex]16

= 8π [tex]$inch^{2}[/tex]

Area of the isosceles triangle = (1/2)bh

= (1/2)(4+4)[tex]\times[/tex]3

= 12 [tex]inch^{2}[/tex]

We add the two areas to acquire the area of the composite figure to be: (8π + 12) [tex]inch^{2}[/tex]

The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].

Therefore, the correct answer is option b. (8π + 12) in.2

Answer:

110-degrees

Step-by-step explanation:

these are alternate exterior angles which are equal *congruent

Answer:

Since 110° and ? are alternate exterior angles, take the 110° and subtract 180°. Remember, 180° is a straight angle. So, 180°-110°= 70°.

The missing angle is 110°, I just solved for the remaining angle to help you figure it out more easily.

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

[tex]\frac{1}{2} \times 100 = 50[/tex]

Add both skateboarding and walking

[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]

Now, subtract that from a whole percent

[tex]100 - 80 = 20\\\\20\%[/tex]

Convert it to a decimal

[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Answer:

(252π + 20) cm²

Step-by-step explanation:

The surface area of the resulting solid = curved surface area of the cylinder + area of 1 base of the cylinder + 2(slant height of the cone)

✔️Curved surface area of cylinder = 2πrh

r = ½(12) = 6 cm

h = 18 cm

C.S.A = 2*π*6*18 = 216π cm²

✔️Area of 1 base = πr²

r = ½(12) = 6 cm

Area = π*6²

Area = 36π

✔️Slant height of the cone = 10 cm

✅The surface area of the resulting solid = 216π + 36π + 2(10)

= (252π + 20) cm²

Hello! Sorry bots answered to quick for last problems

Answer: D. 64

The frequency for A is given as 20, this means A was spun 20 out of 75 spins.

20/75 = 0.2666 which rounds to 0.27

The answer is 0.27

We will see that the experimental probability is P = 0.27, so the correct option is c.

The experimental probability of the outcome A is equal to the quotient between the number of times that the outcome was A and the total number of times that the experiment was performed.

Here we know that the experiment was performed 75 times, and 20 of these 75 times, the outcome was A, then the experimental probability is:

P = 20/75 = 0.27

So the correct option is c.
