Find the measure of a.

Mathematics
1 answer:
Nostrana [21]3 years ago
8 0

Answer:

50 degrees

Step-by-step explanation:

We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles.

fyi, using the same logic, angle b is 25 degrees

Point Q is the midpoint between points P and R on a number line. If the coordinate of point Q is 6 and the coordinate of point P
nekit [7.7K]

Answer:

R = 17

Step-by-step explanation:

Given

P = -5

Q = 6

<em>Midpoint: Q</em>

Required

Determine R

Since Q is the midpoint, then

Q = \frac{1}{2}(P + R)

Substitute values for P and Q

6 = \frac{1}{2}(-5 + R)

Multiply both sides by 2

12 = -5 + R

Add 5 to both sides

12 + 5 = -5 + 5 + R

17 = R

R = 17

The population of a town was 5000 in 2010. The population grows at a rate of 1.4% annually.
kolbaska11 [484]

Answer:

a) P = 5000(1.014)^y

b) 5,908

Step-by-step explanation:

Here, we want to write an exponential growth model;

a)The model will be represented as;

P = 5000( 1.014)^y

where P is the population at a particular year after 2010

y is the number of years after 2010

b.) For 2022;

y = 2022-2010 = 12

P = 5000(1.014)^12

P = 5,908 approximately

leva [86]
0.2 is 10 times as much of... well you must do the opposite of what it says... well, times means to multiply and the opposite of multiplying is dividing, 0.2 divided by 10 is 0.02

So... 0.2 is 10 times as much as 0.02

Now, 0.2 is 1/10 of... well this question shows to divide and we must do the opposite, which is... multiplying 0.2 times 10 is 2

So... 0.2 is 1/10 of 2

Which situation represents a proportional relationship?
Natalka [10]

Answer:

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx

The ratio between the two variables is a constant called constant of proportionality k

k=y/x

<u><em>Verify each case</em></u>

A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

\frac{4}{12}=\frac{9}{25}

Multiply in cross

4(25)=9(12)\\100\neq108

Is not true

therefore

The situation not represent a proportional relationship

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

\frac{5}{25}=\frac{8}{40}

Multiply in cross

5(40)=8(25)\\200=200

Is true

therefore

The situation represent a proportional relationship

C) Larry packed 24 apples in 6 boxes and 46 apples in 9 boxes

\frac{24}{6}=\frac{46}{9}

Multiply in cross

24(9)=46(6)\\216\neq276

Is not true

therefore

The situation not represent a proportional relationship

D) Allie put 14 pieces of candy in 2 bags and 30 pieces of candy in 4 bags

\frac{14}{2}=\frac{30}{4}

Multiply in cross

14(4)=30(2)\\56\neq60

Is not true

therefore

The situation not represent a proportional relationship
