Luke is a locksmith. On weekends he gets paid \$ 64 . 50 per hour, plus a flat rate service fee of \$ 75 for every job. On this Saturday he has three separate jobs that will take 1 1/2, 1/4, and 1 1/4 hours to complete respectively
Answer:
Luke will earn $ 418.50.
Step-by-step explanation:
Given that on weekends Luke gets paid $ 64.50 per hour, plus a flat rate service fee of $ 75 for every job, and on this Saturday he has three separate jobs that will take 1 1/2, 1/4, and 1 1/4 hours to complete respectively, to determine the money you will earn on the day the following calculations must be made:
(75 x 3) + (1.5 x 64.5) + (0.25 x 64.5) + (1.25 x 64.5) = X
225 + 96.75 + 16.125 + 80.625 = X
418.50 = X
So, all Saturday, Luke will earn $ 418.50.

Triangles M N Q and P Q N are connected at side Q N. Triangle M N Q is rotated about point N and then is shifted to the left to form triangle P Q N.
Which transformation(s) can map TriangleMNQ onto TrianglePQN?
translation only
reflection only
rotation, then reflection
rotation, then translation
Answer:
rotation, then translation
Step-by-step explanation:
The transformation that map triangle MNQ onto triangle PQN is rotation, then translation.
The given triangles;
Triangle MNQ Triangle PQNA translation of a triangle occurs when the triangle shifts up, or down, of left or right on the coordinate plane.
The reflection of a triangle occurs when the vertices of the triangle is flipped over the opposite side.
Since the triangle MNQ is rotated then shifted to the left to form the new triangle PQN, we can conclude that the transformation that map triangle MNQ onto triangle PQN is rotation, then translation.

If heat transfers from hot to cold, and stops when two objects reach the same temperature, explain why it is possible for the inside of your car to be hotter than the air outside on a hot summer day.
Does a gas give off or absorb energy when it turns into a solid? Explain your answer.
You dont have to answer both just helping me with one would help me out!!! :)
also robot scammers stop giving me random links
Answer:
1. Consider a hot pot taken off the stove and placed on a tile countertop. At first it cools quickly. As it cools, the difference in temperature between the pot and the room air becomes less, and so it takes a long time for the pot to lose enough heat to match room temperature. Two objects at the same temperature are said to be in equilibrium.
2. When a liquid changes into a gas it absorbs energy. When it changes into a solid it gives off energy...If a solid (dry ice for example) is allowed to sublimate into a gas, it absorbs heat - that's why it feels cold when you touch ice. So, if a gas changes into a liquid, it give off heat as an opposite effect. Anytime you compress a gas, it gets warmer.
Subtract 1 from the product of 4 and 2. what is this in fraction form? please help? A 4 ÷ 2 − 1 B 4 × 2 − 1 C 4 × (1 − 2) D 1 − (4 × 2)
Answer:
D.) 1 - (4 * 2)
Step-by-step explanation:
Given :
Product of 4 and 2 is written as : 4 * 2
Subtracting 1 from the product above : 1 - (4 *2)
Hence, the fractional form of the question above is simply written as :
1 - (4 * 2)
The average area of a bedroom in a home is 219 square feet with a standard deviation of 32.5 square feet. What is the largest a bedroom can be and be among the smallest 25% of bedrooms in a home?
Answer:
197.095
Step-by-step explanation:
Mean, m = 219 ft²
Standard deviation, s = 32.5 ft²
For a bedroom to be among the smallest 25%
P(x < Z) = 0.25
From Z probability calculator, this corresponds to a Zscore of - 0.674
Recall :
Zscore = (x - m) / s
x = bedroom size
-0.674 = (x - 219) / 32.5
-0.674 * 32.5 = x - 219
-21.905 = x - 219
x = - 21.905 + 219
x = 197.095
Hence, the largest a bedroom can be and still be among the smallest 25% is 197.095

I didn't pay attention in class for a few days and now I'm lost. if somebody could at least explain proportions I would be very thankful.
Answer:
A proportion is a comparison of two numbers that each represent the parts of a whole. Essentially, a proportion says that two fractions are the same, even if the amount is different. For example, 1/2 of 10 marbles is the same proportion as 1/2 of 50 marbles.

Hi! i'm showing this to my sister and she wants to know, At a yard sale, Jennifer sold 2 tricycles for $22.50 each, 3 old video games for $2.75 each, a video for $5.00, and a dictionary for 75 cents. How much money did she make?
Jennifer made $59.
$22.50 times 2 is $45 and $2.75 times 3 is $8.25, the sum of these numbers is $53.25.
$5 plus $0.75 is $5.75, and the sum of $5.75 plus $53.25 is exactly 59 dollars.
If this is incorrect, please, don't refrain to tell me.

In the figure below, m∠1 = x and m∠2 = x - 8. Which statement could be used to prove that x = 49?
Answer:
see explanation
Step-by-step explanation:
∠ 1 + ∠ 2 = 90, that is
x + x - 8 = 90
2x - 8 = 90 ( add 8 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
Sierra has enough fencing to make three chicken coops shown each has the same perimeter which has the greatest area?
Answer:
Top left triangle has the greatest area
Step-by-step explanation:
Area of a triangle:
area = base × height / 2
a = bh/2
Top Left Triangle:
a = 6 × 5.2 / 2
a = 31.2 / 2
a = 15.6
Top Right Triangle:
a = 8 × 2.9 / 2
a = 23.2 / 2
a = 11.6
Bottom Left Triangle:
a = 2 × 7.9 / 2
a = 15.8 / 2
a = 7.9
Compare areas:
15.6 > 11.6 > 7.9

6. x² + 8x + 7
= x² + 7x + x + 7
= x (x + 7) + 1 (x + 7)
= (x + 1) (x + 7)
Option D is the answer.
7. x² - x - 72
= x² - 9x + 8x - 72
= x(x - 9) + 8(x - 9)
Option B is the answer.
8. x² - 49
= (x - 7) (x + 7) [formula used a² - b² = (a-b)]
Option D is the answer.
9. 9x² - 54x + 72
= 9(x² - 6x + 8)
= 9(x² - 4x - 2x + 8)
= 9[x(x-4) -2 (x-4)]
= 9[(x - 2) (x - 4)]
= Option A is the answer.
10. x⁴ - 3x³ - 10x²
= x² (x² - 3x - 10)
= x² (x² - 5x + 2x - 10)
= x² [x (x-5) + 2 (x-5)]
= x² (x+2) (x-5)
Option A is the answer.

find the median 60,62,64,54,56,28
Answer:
58
Step-by-step explanation:
you need to order all the numbers together:
28, 54, 56, 60, 62, 64
since the middle 2 are 56 and 60 you need to find the average of those.
(56 + 60)/2 = 58
Ahmed invests $1,500 at an interest rate of 4%, compounded quarterly and another $1,500 at an interest rate of 3.75%, compounded annually. How much are the investments worth in total at the end of 6 years?
Answer: $1904.60
Step-by-step explanation:
This is 1500(1+.04/4)^24 where .04/4 is the interest rate for each compounding, or the interest rate /4, for 4 quarters.
The 24 is 4 quarters/year * 6 years
round at the end
=$1904.60
