Answer:
Hope this helps : )
You should shade in 1 whole rectangle on the the bottom left corner and the top half of the second rectangle the bottom right corner.
Step-by-step explanation:
This is because 1 1/2 is one whole rectangle and half of another rectangle. However, in this case the second rectangle on the bottom right corner is split into sixths. So half of it is 3/6 which is equal to 1/2.

A state government borrows $2,000,000 at simple annual interest. Some of the money is borrowed at 6%, some at 7.5%, and some at 8.5%. Use a system of linear equations to determine how much (in dollars) is borrowed at each rate given that the total annual interest is $137,000 and the amount borrowed at 7.5% is four times the amount borrowed at 8.5%. Solve the system of linear equations using matrices.
If the amount borrowed at 7.5% is four times the amount borrowed at 8.5%. The amount borrowed is: $200,000, $800,000, $1,000,000.
How to find the amount borrowed?Now let find the amount borrowed
Let X+Y+Z = 2000000
0.06X + 0.075Y + 0.085Z = 137000
Y = 4Z
Substituting Y=4Z into the first and second equations:
X + 5Z = 2000000
0.06X + 0.075(4Z) + 0.085Z = 137000
X = 2000000 - 5Z
0.06X + 0.385Z = 137000
0.06(2000000 - 5Z) + 0.385Z = 137000
120000 - 0.3Z + 0.385Z = 137000
0.085Z + 120000 = 137000
0.085Z = 17000
Divide both side by 0.085Z
Z= 17,000/0.085
Z = 200000
So,
Y = 4Z
Y = 800000
X= 200,000 + 800,000
X = 1000000
Hence,
Z = 200000
Y = 800000
X = 1000000
Therefore the amount borrowed is: $200,000, $800,000, $1,000,000.

∆abc and ∆def satisfy the aaa correspondence. ∆abc and ∆def . is not a criterion for congruency of any two triangles.
Triangles ABC and DEF might or might not be congruent since the angle-angle-angle (AAA) postulate is not a requirement for congruency of any two triangles. This is due to the fact that the angle-angle-angle postulate only takes into account the triangles' angles and does not specify their side lengths, hence congruency for these triangles may or may not be true.
What is a congruent triangle?
Therefore, if two triangles have the same number of sides on each side, they are said to be congruent.
Additionally, we can determine if they are congruent if we have a side, an angle between the sides, and then another side that is congruent, in that order: side, angle, side.

The transmission of audio and video data electronically between a source and a recipient.
The primary use of television is to transmit shows for entertainment, information, and education. Television is a system for transmitting visual images and sound that are reproduced on screens.

numerical value of the product of their ages is equal 4 times the sum of their
Find the present ages of the sister and her brother.
Answer:
bother = 6 years ; sister = 12 years
Step-by-step explanation:
s = sister
b = brother
s - b = 6
s * b = 4(s+b)
s = b + 6
b(b+6) = 4(b+6 + b)
b² + 6b = 4(2b + 6)
b² + 6b = 8b + 24
b² + 6b - 8b - 24 = 0
b² - 2b - 24 = 0
(b-6)(b+4) = 0
b = 6
b = -4 (impossible because an age can’t be negative)
s = 6 + 6
s = 12
I have a job that pays me 40 dollars an hour. However, it's far away and I pay $250
a week on gas. I have another job that's closer, but it only pays 25 dollars an hour
and I only spend 100 dollars on gas a week. What should I do? Use math to
support your answer. (Calculate this problem on a monthly basis. On both jobs, he
would work 160 hours per month.)
Answer: The first job seems better.
Step-by-step explanation:
If 1 month = 4 weeks:
40 x 40 = 1600 per week
40 x 160 = 6400 per month
250 per week on gas
250 x 4 = 1000 per month on gas
1600 - 250 = 1350
6400 - 1000 = 5400
You would earn $1350 per week on the first job, and $5400 on this job.
_____________________________________________________
25 x 160 = 4000 per month
25 x 40 = 1000 per week
100 per week on gas
100 x 4 = 400 per month on gas
1000 - 100 = 900
4000 - 400 = 3600
$900 per week on the second job, and $3600 per month on this job.
Hello,
I hope you and your family are doing well!
To compare the two jobs and determine which one is more financially advantageous, you need to calculate the total income and total expenses for each job on a monthly basis.
For the first job, the total income is 40 dollars per hour * 160 hours per month = 6400 dollars per month. The total expenses are 250 dollars per week * 4 weeks per month = 1000 dollars per month. The net income is 6400 dollars per month - 1000 dollars per month = 5400 dollars per month.
For the second job, the total income is 25 dollars per hour * 160 hours per month = 4000 dollars per month. The total expenses are 100 dollars per week * 4 weeks per month = 400 dollars per month. The net income is 4000 dollars per month - 400 dollars per month = 3600 dollars per month.
Based on these calculations, the first job is more financially advantageous because it has a higher net income. You would earn an additional 1800 dollars per month by working the first job instead of the second job.

(1 point)
The values of x and w on the triangle are given as follows:
w = 14.4, x = 11.2.
How to obtain the values of x and w?The values of x and w are obtained applying the trigonometric ratios, as the triangle is a right triangle.
The three trigonometric ratios are given as follows:
Sine of angle = length of opposite side divided by the length of the hypotenuse.Cosine of angle = length of adjacent side divided by the length of the hypotenuse.Tangent of angle = length of opposite side divided by the length of the opposite side.For the angle of 48º, we have that:
The adjacent side is w.The opposite side is of 16.Hence:
tan(48º) = 16/w
w = 16/tan(48º)
w = 14.4.
For the angle of 32º, we have that:
The adjacent side is 14.4 + x.The opposite side is of 16.Hence:
tan(32º) = 16/(14.4 + x)
tan(32º)(14.4 + x) = 16
x = (16 - 14.4tan(32º))/tan(32º)
x = 11.2.
