solve for x please i need help
Answer:
x = 4
Step-by-step explanation:
By exterior angle theorem:
(9x + 1)° + (11x - 2)° = (19x + 3)°
(9x + 1 + 11x - 2)° = (19x + 3)°
(20x - 1)° = (19x + 3)°
20x - 1 = 19x + 3
20x - 19x = 3 +1
x = 4

Answer:
16. 134°
17. 20°
18. 94°
Step-by-step explanation:
An inscribed angle is half the measure of the arc it intercepts.
__
16. Arc QT is twice the measure of inscribed angle QST, given as 67°.
Arc QT = 2×67°
Arc QT = 134°
__
17. Angle STR is half the measure of arc SR, so is ...
m∠STR = (arc SR)/2 = 40°/2
m∠STR = 20°
__
18. Arc RST is a semicircle, so has a measure of 180°. Then arc ST is the difference between that and arc RS:
arc ST = 180° -40° = 140°
Angle RST subtends a semicircle, so is 180°/2 = 90°. We know angle QST is 67°, so the remaining portion, angle QSR must be the complement of that:
m∠QSR = 90° -67° = 23°
Arc RQ will be twice this measure, or 46°.
So, the desired difference is ...
mST -mRQ = 140° -46° = 94°

Write 24 as a product of primes.
Use index notation when giving your answer.
Answer:
2^3 * 3
Step-by-step explanation:
Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23
To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.
This is much easier to do than it sounds like in this explanation.
Start with 24.
24/2 = 12
12/2 = 6
6/2 = 3 3 is not divisible by 2, so we move on to 3.
3/3 = 1 We got to 1, so we are done.
The prime factorization is the product of all the prime numbers we divided by which are in bold.
24 = 2 * 2 * 2 * 3
Now we index it:
24 = 2^3 * 3

The regular cost for a day pass at the swimming pool is $8. Nancy and Rachel are students at the local elementary school, so they each get a $1.25 discount. How much will they pay altogether for a day at the pool? *
Answer:

Step-by-step explanation:
(8*2) - (1.25*2) =

Linda headed east at 20 miles per hour on her bicycle at 9 a.m. Three hours later Shanna headed west from the
same place, walking at 6 miles per hour. What time was it when they were 164 miles apart?
Step-by-step explanation:
Let t = time (in hrs) Linda rode her bike
Then (t-3) = Shana's time walking
:
Write a distance equation: dist = speed * time
:
Linda's dist + Shana's dist = 164
20t + 6(t-3) = 164
20t + 6t - 18 = 164
26t = 164 + 18
26t = 182
t = 182/26
t = 7 hrs, Linda is on the road
:
Time: 9 AM + 7 hrs = 4 PM, they will be 162 miles apart
:
Check using Linda's and Shana's distances:
20(7) + 6(7-3) =
140 + 24 = 164 mi

Oliver is starting a running plan to train for a race. In the first week of his running plan, Oliver will run 14 miles. The plan calls for Oliver to increase his weekly milage by 3.5 miles every week. If Oliver sticks to the plan, how many miles would he be expected to run during his 10th week of the training plan?
Answer:
49 miles
Step-by-step explanation:
Let x be equal to the no. of weeks and y be equal to the total amount of miles ran.
Then the equation will be, y = 3.5x + 14
Now to find the amount of miles Oliver ran during the 10th week substitute 10 for x.
So, y = 3.5(10) + 14
y = 35+14
y=49

Step-by-step explanation:
Your savings account pays 1.75% interest per year. You make a $500 deposit. How much interest does the account earn in the first month.
The interest the account earn in the first month is = $0.73
The amount deposited( = $500
The payment rate per year = 1.75%
The payment time = per year(12 months)
Therefore simple interest in first month=
[tex] \frac{p \times t \times r}{100 \times 12} [/tex]
[tex] \frac{500 \times 1 \times 1.75}{100 \times 12} [/tex]
[tex] \frac{875}{1200} [/tex]
=$0.73
Therefore, the interest the account earn in the first month is = $0.73

Using the given exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Type your answers in as numbers. Example: Growth Factor: 3.5, Rate of Increase: 2.5. (Do not input your rate of increase as a percent. If there are fractions, you can input your answer as a fraction. i.e. - 4/5, or 1/10)
f(x)=200(4/5)^x
Answer:
Growth rate is -1/5
Growth factor is 4/5
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Generally for an exponential function given as;
y = a(1 + r)^n
r is the growth rate
1 + r is the growth factor
We can express the given exponential function as follows;
f(x) = 200(1-1/5)^x
So the growth rate is -1/5
The growth factor is 1-1/5 = 4/5

f(x)=75(1-.3)^x
Answer:
0.7 is the growth factor
0.3 is the growth rate
Step-by-step explanation:
Here, we want to get the growth rate and the growth factor
Let us consider the general form of an exponential equation
That will be;
y = a(1 + r)^n
The growth rate is r
while the growth factor is the term (1 + r)
From the given exponential function;
-0.3 is the rate of increase
Growth rate is 1-0.3 = 0.7
