Answer:
1. D
2. B
3. A
4. C
Step-by-step explanation:
1. The third side can't be calculated with given information
2. This is right triangle so you can use Pythagorean theorem to find hypotenuse.
6^2 + 8^2 = c^2
36 + 64 = c^2
100 = c^2
10 = c = PR
Since PM = RM, you would take half of c to find PM. So PM = 5
3. When writing congruency statement, you have to be careful with orders.
Angle A is congruent to angle E.
Angle B is congruent to angle D
So if A comes first, then E should be written first for the other side (does that make sense?)
4. For SAS, you need 2 congruent sides and 1 congruent angle. But that angle has to be in between two congruent sides.

Find the 91st term of the arithmetic sequence 4, 6, 8,
Answer:
184
Step-by-step explanation:
Find the common difference first d = 6 - 4 = 2
first term a_1 = 4
a_n = (n -1)*d + a_1
a_91 = (91 - 1) * 2 + 4
a_91 is the 91st term:
a_91 = 90*2 + 4
a_91 = 180 + 4 = 184
The company makes a single serving cereal box that contains a volume of 1.2 ounces of cereal. They plan to make an extra large box for school cafeterias. The extra large box will be a dilation of the single serving box using a scale factor of 9/2
. How many ounces of cereal will the extra large box contain?
Answer:
109.35 ounces
Step-by-step explanation:
The scale factor is a linear scale factor.
The box is a three-dimensional solid, so the length, width, and height will be dilated by a factor of 9/2.
The volume factor is (9/2)³ = (4.5)³ = 91.125
The number of ounces is proportional to the volume.
1.2 ounces × 91.125 = 109.35 ounces
Footware manufacturing is projected to decrease output by 8. 4% from 2006 to 2016. If footware manufacturing had 1. 8 billion dollars of output in 2006, approximately how much output is expected in 2016? a. $1. 95 billion b. $2. 64 billion c. $1. 55 billion d. $1. 65 billion.
Percentage is a way to describe a part of a whole. The production of the footwear that will be in 2016 will be 1.65 billion.
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
It is given that the production of footwear in 2006 was 1.8 billion which will be reduced by 8.4%, therefore, the number of footwear that will be produced in 2016 is 91.6%(100%-8.4%) of the production in 2006. Therefore, the production of footwear in 2016 will be
[tex]91.6\%\ of\ 2006\\\\= 0.916 \times 1.8\ billion \\\\= 1.6488\approx 1.65\ billion[/tex]
Hence, the production of the footwear that will be in 2016 will be 1.65 billion.

What is the yearly salary for the RN working 40 hours
a week? How much more is an RN paid in a year than
an LPN?
Helpppppppppp
Answer:
RN = registered nurse
LPN = licensed practice nurse
RN earns $21.50 per hr
LPN earns $14 per hr
To calculate earnings for a 40 hour working week, multiply the rate per hour by 40:
RN earns: 21.50 × 40 = $860 per week
LPN earns: 14 × 40 = $560 per week
Difference: 860 - 560 = $300
Therefore, an RN is paid $300 more than an LPN for a 40 hour working week.
Number of weeks in a (non leap) year = number of days in a year ÷ 7
= 365 ÷ 7
= 52.14285714...
Rounding to the nearest whole number ⇒ 52 weeks in a year
To calculate the yearly salary, multiply the rate per week by 52:
RN earns: 860 × 52 = $44720 per year
LPN earns: 560 × 52 = $29120 per year
Difference: 44720 - 29120 = $15600
OR we can simply multiply the difference between the amount paid for a 40 hour week by 52:
⇒ 300 × 52 = $15600
Therefore, an RN is paid $15600 per year than an LPN.

Step-by-step explanation:
Which of the fractions below has a numerator of 3? Select all that apply.
A)38
B)23
C)25
D)38
E)312
Answer:
A and C
Step-by-step explanation:
When you are dividing exponents you subtract. So for this problem -8 - -4 = -8 + 4 = -4. This means that the new exponent would be -4.
When you have a negative exponent, the equation is a fraction. As an example x^-5 would be equal to 1/x^5. For this equation, since you know that the new exponent is -4, an equivalent equation would be 1/3^4.

Answer:
21
Step-by-step explanation:
If the angles are supplementary, that means they add up to 180 degrees.
That means if we subtract 75 from 180, we get 105.
If we divide 105 by 5, we get 21.
That means 21 * 5 + 75 = 180
or
5(21) + 75 = 180
Hope this helps!
