Answer:

  x = 58

Step-by-step explanation:

The external angle is half the difference of the intercepted arcs.

  (160° -x°)/2 = 51°

  160 -102 = x = 58

Answer:

For the yes/no bit:

step 1: no

step 2: no

step 3: yes

step 4: yes

step 5: no

for the final answer bit: a = 2  3/5 (the last option)

Step-by-step explanation:

yes/no bit:

step 1 is wrong because she didn't multiply [tex]-\frac{5}{4}a[/tex] by -2

step 2 is wrong because she subtracted 1/2 instead of adding it

step 3 is correct because 6 - 1/2 = 11/2

step 4 is correct because she correctly multiplied both sides by 4

step 5 is wrong because she added 5 instead of dividing by -5.

for the final answer bit, I've attached an image below with my working out. hope this helps!

Answer:

Step-by-step explanation:

Area of square = 144 sq ft

Area of circle = πr² = 36π sq ft

Total area = (144+36π) sq ft

Square section of pond is 10 ft by 10 ft, area = 100 sq ft

Circular area of pond has diameter of 8 ft.

Area = πr² = 16π sq ft

Area of pond = (100+16π) sq ft

Area of border = (144+36π)-(100+16π) = (44+20π) sq ft

Step-by-step explanation:

Answer:

$84.504

Step-by-step explanation:

20% of 70.42 is 14.08, 14.08 plus 70.42 is 84.504

Answer:

1. Domain: [0,120] Range: [0,300]

2. f(30) = 200; After 30 minutes, the altitude of the balloon is 200 feet.

3. x = 10; When the altitude of the balloon is 100 feet, the time has passed is equal to 10 minutes.

4. at 20-40 minutes

5. 70 minutes

6. x: {40 ≤ x ≤ 90}

Step-by-step explanation:

1. The line is between 0 and 120 on the x-axis and is between 0 and 300 on the y-axis.

2. When x = 30, y equals 200.

3. When y = 100, x equals 10.

4. The line stays on 200 for 20 minutes, between 20 and 40.

5. Between 30 and 100 minutes, the altitude is greater than 200.

6. All x values between 40 and 90 (including 40 and 90 too) matches with 300 as their y-coordinate.

Answer:

40°

Step-by-step explanation:

110 + 30 is 140. Since the sum of every triangle's angles are 180, you do 180-140. the answer is 40

Answer:

73/4

Step-by-step explanation:

18x4 = 72. 72 + 1 = 73

Answer: 73/4

Step-by-step explanation:

An improper fraction is simply a fraction in which the numerator is larger than the denominator.  Thus, simply convert 18 into fourths, 72/4, then add 1/4 to get 73/4

Answer:

30g

Step-by-step explanation:

Since the bag is a total of 150 grams...

100% = 150

1% = 150 ÷ 100 = 1.5

Find out 80% of the bag which is finding out how many raspberries there are in the bag.

80% = 1.5 x 80 = 120

The remaining in the bag out of the raspberries is the berries.

150 - 120 = 30 (berries)

Answer:

12.04 units squared

Step-by-step explanation:

You need to find X first

3x+4 = 2x-5

5x = -9   (Divide both side by 5)

x = -1.8

Substitute X into the equations

(3x+4) = -1.4

(2x-5) = -8.6

Find the Area with the given number

A = (3x+4) x (2x-5)

A = -1.4 x -8.6

A = 12.04

Step-by-step explanation:

circumference(c)=43.96

2πr=43.96

r=43.96÷2π

radius ( r)=7

Now,

area(a)=πr^2

=3.14×49

=154

Answer: ABC is bisected by ray BD.

BC = One-halfAC

2mDBC = mABC

Step-by-step explanation:just took the test :)

The solution is, Options B, C and D are correct choices.

B.) ABC is bisected by ray BD.

C.) BC = AC/2

D.) 2mDBC = mABC

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

We have been given a diagram in which point B is the midpoint of line ABC. We are asked to choose the correct statements about our given diagram.

A. DBC is bisected by ray BD.

Since DBC is an angle for our given diagram and side BD is terminal side of angle DBC, therefore, option A is false.

B. ABC is bisected by ray BD.

We have been given that point B is the midpoint of segment ABC, this means that ray BD bisect line ABC. Therefore, option B is true.

C.

Since point B is midpoint of line ABC, so AB will be equal to BC.

i.e. we get,

BC = AC/2

Therefore, option C is the correct choice.

D. 2mDBC = mABC

We can see that measure of angle DBC is 90 degrees.

We can see that ABC is a line and measure of linear angle is 180 degrees,

therefore,  and option D is true.
