Julie borrowed money to repair her home. She borrow $3000 less from her Uncle than her Aunt. The money
she borrowed from her Aunt was at 2.2% simple interest. The money she borrowed from her Uncle was at
4.5% simple interest. Julie paid the loans back in 3 years. She paid $2007 in interest. How much did Julie
borrow from her Aunt and how much from her Uncle?
Julie borrowed $12,000 from her aunt and $9000 from her uncle
Note the formula for simple interest = principal x time x interest rate
This question would be solved using simultaneous equation.
Two equations can be derived from the question
a - b = 3000 equation 1
(0.022 x 3 x a) + (0.045 x 3 x b) = 2007
0.066a + 0.135b = 2007 equation 2
where
a = amount borrowed from aunt
b = amount borrowed from uncle
Multiply equation 1 by 0.066
0.066a - 0.066b = 198 equation 3
subtract equation 3 from 2
0.201b = 1809
divide both sides of the equation by 0.201
b = 9000
Substitute for b in equation 1
a - 9000 = 3000
a = 9000 + 3000
a = 12,000

If f(x)=−2(x+7), then what is f(−10)?
Answer:
f(-10) = 6
Step-by-step explanation:
f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.
Since they want you to find f(-10), you'll then plug -10 in where x was and solve.
f(-10) = -2((-10)+7)
f(-10) = -2(-3)
f(-10) = 6
Answer:
[tex]→f(x) = - 2(x + 7) \\ f( - 10) = - 2( - 10 + 7) \\ f( - 10) =( - 2) \times ( - 3) \\ \boxed{f( - 10) = 6}✓[/tex]

GIVING 12 POINTS
If a car is 13.5 feet long and there are 3 feet between each car, how many cars can be on a mile section of the highway?
1 mile = 5,280 feet
Car + space = 13.5 + 3 = 16.5 feet
5,280 / 16.5 = 320
Answer: 320 cars
1 mile is equals to 5280 feet from this reference we will solve our question
total number of cars that can be on the mile section of the highway is = [tex]\frac{5280}{16.5}[/tex] cars = 320 cars.
How to convert units ?There are some fundamental units which acts as the base of all other units derived from it and a single unit can be defined in many form for large and small magnitudes for our convenience.
In this question car is 13.5 feet long and there is 3 feet distance between each car so the total space is (13.5 + 3) = 16.5 feet
So in 1 mile or 5280 feet the total number of cars that can be on the mile section of the highway is = [tex]\frac{5280}{16.5}[/tex] cars = 320 cars.

how do you convert a repeating decimal in the 10000 place into a fraction?
Decimal to Fraction
Converting any terminating decimal into a fraction is fairly straightforward. You count the number of decimal places, move the decimal point that number of places to the right, and put the resulting number over "1" followed by that number of zeroes.
For instance:
Convert the decimal 0.7 into a fraction.
This decimal has one decimal place, so I move the decimal point one place to the right, to get 7. Then I put this over "1" followed by one zero (otherwise known as "10") to get: 7/10

Answer:
Answer: y = (2k -pw)/p
Step-by-step explanation:
[tex]k = \frac{p}{2} (y + w)[/tex]
multiply 2 on both sides:
[tex]k \times 2 = 2 \times \frac{p}{2} (y + w) \\ \\ 2k = p(y + w)[/tex]
open the bracket:
[tex]2k = py + pw[/tex]
subtract pw from both sides:
[tex]2k - pw = (py + pw) - pw \\ 2k - pw = py[/tex]
divide p on both sides:

one stick is 10cm longer than another, ⅖ of the longer stick is equal to ½ of the shorter stick. find the length of the longer stick
Answer:
50cm, the short stick is 40cm
Step-by-step explanation:
1/2 + 1/2 = 1
2/5 + 2/5 = 4/5
1/5 = 10 (because the tall stick is 10 cm taller than the other stick)
10 x 5 = 50
10 x 2 = 20
1/2 = 20
20 + 20 = 40
5) Emily woks Monday through Friday at a rate of $16.12 per hour. She takes a 1-hour lunch break. If she
clocks in each day at 6:15 A.M. and leaves at 4:15 P.M., what is her total pay for the week? (show your
work)
Answer:
$
725.40
Step-by-step explanation:
Since, every day she works from 6:15am to 4:15pm
this will put her working to 10 hrs a day and subtracting 1 hr break, the total working period would be 9 hrs a day.
And, total working hours per week would be (9*5) hrs = 45 hrs
thus, her total salary per week would be $(45*16.12) = $725.40
A firefighter training course is taking place in a high-rise building. The high-rise building where they practice is 48 stories high. If the emergency happens on the top floor and the firefighters have already gone 29 stories, how many stories do they still need to go?
Answer:
29 stories - 49 stories = number of stories they need to go
28 - 49 = 21
the answer is 21
they have 21 more stories to go
The number of stories they still need to go is 19 stories.
It is given that building is 48 stories high and when the emergency happens they have already gone to 29 stories.
We have to calculate the number of stories they still need to go.
What will be the value, if we subtract 2 from 4 ?
The value after subtracting will be 4 - 2 = 2.
As per the question ,
The total number of stories in building = 48
When emergency happens they have already gone 29 stories.
So ,
The number of stories they still need to go after the emergency happens can be calculated as ;
48-29 = 19
Thus , they still need to go 19 stories.

The triangles are congruent with SSS postulates. Then the correct option is D.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
Two triangles are shown.
The SSS postulate is one of the ways to prove that two triangles are congruent. SSS stands for "side-side-side," and it states that if three sides of one triangle are congruent to the corresponding sides of another triangle, then the two triangles are congruent.
The corresponding sides of the triangle will be equal. Then the triangles are congruent with SSS postulates.
Thus, the correct option is D.

Below,... ;->
Step-by-step explanation:
With Multiplication and Division you just carry out normal Multiplication and Division. If the equation has an EVEN number of negative signs the answer will always be positive (the sign cancel each other out). In turn if there is an ODD number of negative signs the answer will always be negative,... (with Addition and Subtraction it is different but with Multiplication and Division working out problems works in this way,...)
1 = 96 (even number of negative signs,... (in the whole equation))
2 = -4 (odd number of negative signs)
3 = -60
4 = -176
5 = 44
6 = -76
7 = -64
8 = 306
9 = 64
10 = 48
11 = 24
12 = 48
13 = -7 (do the division like you normally would except now just add the neg sign when appropriate (in this case there is 1 neg sign so answer is neg))
14 = 16
15 = -7
16 = 2
17 = -4
18 = 13
19 = 5 (do the parenthesis first (order of operations))
20 = 5 (do the parenthesis first (order of operations))
OKAY,... I think that does it,... Best of luck! Hope that helps,... Chow,...!
