Elena works at an appliance store. She recorded her recent sales.
ovens 5
washing machines 6
dishwashers 4
Of the next 12 appliances Elena sells, how many should she expect to be ovens, given the past data?
Using proportions, it is found that she should expect 4 of the next 12 appliances to be ovens.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that out of 15 items, 5 are ovens. How many will be out of 12? To find out, we start with the rule of three.
15 items - 5 ovens
12 items - x ovens
Applying cross multiplication:
15x = 60
x = 4.
Hence, 4 of the next 12 appliances to be ovens.

A newspaper advertisement offers a $6500 used car for nothing down and 36 easy monthly payments of
$196.80. What is the total amount paid for the car, and what is the total finance charge? Calculate the
simple interest rate charged.
Total Amount:
Total Finance Charge
$
Simple Interest Rate:
%
Using simple interest, it is found that:
The total amount paid was of $7,084.8.The finance charge was of $584.8.The simple interest rate was of 3%.Simple InterestSimple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
[tex]I = Prt[/tex]
In which:
P is the initial amount.r is the interest rate, as a decimal.In this problem, the amount paid was of 36 monthly payments of
$196.80, hence:
36 x 196.80 = $7084.8.
The total amount paid was of $7,084.8.
The original price is of $6,500, hence the finance charge was of:
7084.8 - 6500 = $584.8.
For interest, we have that:
[tex]I = 584.8, P = 6500, t = 3[/tex], hence:
[tex]I = Prt[/tex]
[tex]584.8 = 6500(3)r[/tex]
[tex]r = \frac{584.8}{6500 \times 3}[/tex]
[tex]r = 0.03[/tex]
The simple interest rate was of 3%.

Find the value of each variable in the parallelogram. Please help!
Answer:
m = 35 , n = 110
Step-by-step explanation:
the opposite angles of a parallelogram are congruent , then
2m = 70 ( divide both sides by 2 )
m = 35
consecutive angles are supplementary, that is sum to 180° , then
n + 70 = 180 ( subtract 70 from both sides )
n = 110
Solution:
We know that:
In a parallelogram, opposite angles are equivalentThis means that:
70 = 2mDivide 2 both sides to find m:
70 = 2m70/2 = 2m/2m = 70/2 = 35°We can see that two angles measuring 70° and n° are a linear pair.
n + 70 = 180n = 180 - 70 = 110°PLS HELP!

Step-by-step explanation:
x²+4x=8
rearrange
x² + 4x - 8 = 0
half of 4 is 2
so

Find the perimeter of the parallelogram with these vertices.
(6,4),(-1, 4), (1, -5), (-6, -5)
Answer:
34.6
Step-by-step explanation:
The perimeter of a plane geometric figure is the sum of its side lengths. This figure has two horizontal sides, so their length is easy to compute. It also has two diagonal sides, so the distance formula or Pythagorean theorem must be invoked to find their length.
The length of diagonal AC is ...
d = √((x2 -x1)² +(y2 -y1)²)
d = √((1 -6)² +(-5 -4)²) = √((-5)² +(-9)²) = √106 ≈ 10.3
The length of each horizontal segment can be found by counting grid squares or by finding the difference of x-coordinates.
AB = 6 -(-1) = 6 +1 = 7
__
Two sides have length 10.3 and two sides have length 7, so the perimeter is ...
P = 2(10.3 +7) = 34.6 . . . units

Answer:
Step-by-step explanation:
Find the missing angles
Answer:
z=116 (opposite angles are equal)
y=180-(116+27)=37(angles in a triangle sum up to 180)
x:
(z) + (27+x) =180(interior angles on same side are supplementary

Jennifer needs to fit 28 t-shirts into her
new dresser. Each drawer can hold 6
shirts. How many drawers will she need
to use to put all of the t-shirts away?
[?] drawers
Hint: if your quotient has a remainder,
you will need to add one more drawer
so that all of the shirts can be put away.
Enter
Answer:
SO 28 new t shirts.
Each drawer can hole 6 tshirts.
How many drawers needed.
Now this is a division problem, how many “6 tshirts” can fit into 28 t shirts.
Something like that.
Anyways its 28/6 or 28 ÷ 6 = 4 remainder 4
4 r 4
Now we need all t shirts put away not 24 and have 4 left over. So we can just get another drawer and add it to the whole number.
So 5 drawers
