Mariah borrowed $1200 to buy a new computer system. She paid the simple interest loan off in 24 monthly payments of $56 each. What was the interest rate of this loan? a.2%
b.6%
c.4.4%
d.7%
Answer:
B. 6%
Step-by-step explanation:
Answer:
6%
Step-by-step explanation:
Her 24 monthly payments total 24 x $56 = $1344
That means that $1344 - $1200 = $144 is just interest. What percent is this of her loan amount? Divide to find out:
144 / 2400 = 0.06 = 6%

Answer:
38°
Step-by-step explanation:
The measure of angle NPM is 38°.
➠ ∠MPJ + ∠LPM = 180°
➠ ∠MPJ + 90° = 180°
➠ ∠MPJ = 180° – 90°
➠ ∠MPJ = 90°
∠NPM = ∠MPJ – ∠JPN
➠ ∠NPM = 90° – 52°
➠ ∠NPM = 38°
∴ Required answer :∠NPM = 38°Solve for x.

Sally plays a game for 1 and 5-sixths hours. Judy plays a game 1-half hour longer than Sally. Question How many hours does Judy play her game? Move numbers to the boxes to show the answer. If there is no whole number, put a 0 in the first box.
Answer:
2 1/3 hours or 2 hrs, 20 min
Step-by-step explanation:
1 5/6 + 1/2
make mixed number into improper fraction and change 1/2 to 3/6
11/6 + 3/6 = 25/6
14/6 equals 2 2/6 which simplifies to be 2 1/3 or 2 hrs, 20 min

How to make a data set with only 5 numbers. And so the mean is 7, the median is 7, and the mode is 5?
Answer:
5,5,7,8,10
Step-by-step explanation:
mode=5 so that would appear the most so start with 5,5
median=7 that would be the middle number so 7 would be next
when you add 5+5+7=17 now just choose any number to add to 17 and I choose 10 which makes 17+10=27.
mean=7 so that means the total has to be divided by how many numbers you have, which is 5. So the total divided by 5 should equal 7. Since have 27, the number divided by 5 to get 7 is 35. So, add to 27 to get 35 which would be 8.
27+8=35 that is your total. Now divide by 5 to get the mean of 7.
Please help! Math is my worst subject
Answer:
it's answer is 73°
Step-by-step explanation:
< DCB = 50°
< ACB = x
< CAB = 57°
< ABC = < DCB = 50° {Being alternate angles }
Now
x + 50° + 57° = 180° { being sum of angles of triangle }
x + 107° = 180°
x = 180° - 107°
Therefore x = 73°
Hope it will help :)❤
Quadrilateral JKLM has side lengths of JK = 2y + 3, KL = 8x – 10, LM = 5y – 6, and JM = 3x + 20. Find the values of x and y that make quadrilateral JKLM a parallelogram. A. X = 6, y = 6 B. X = 6, y = 3 C. X = 13, y = 3 D. X = 2, y = 1
Answer:
(6, 3)
Step-by-step explanation:
Note that the opposite side of parallelogram are congruent, hence;
Jk = LM
2y + 3 = 5y - 6
2y - 5y =-6 - 3
-3y = -9
y = 9/3
y = 3
Similarly;
KL = JM
8x – 10 = 3x+20
8x - 3x = 20 + 10
5x = 30
x = 30/5
x = 6
Hence (x,y) is (6, 3)

Which expression is equivalent to 14 x minus 21 over 7 ?
Answer:
-42
Step-by-step explanation:
Which expression is equivalent to 14 x minus 21 over 7 ?
Mathematically this expression is written as:
= (14 × -21)÷ 7
= (14 × -21)/7
= - 294/7
= -42
Therefore, the equivalent of the above expression is calculated as -42

A rectangular logo is made up of 3 squares and 8 small squares the length of the rectangle is 36 cm
Find the area of the logo
Answer:
The total area is 594cm.²
Step-by-step explanation:
The top and bottom each have a length of 36 cm.
Blue side:
36/3= 12cm. (36/3 for the length of one side of a blue square)
12*12= 144cm.² (area of one blue square)
144*3= 432cm.² (area of all the blue squares)
Orange side:
36/8= 4.5cm. (the length of one side of an orange square)
4.5*4.5= 20.25cm.² (the area of one orange square)
20.25*8= 162cm.² (the area of all the orange squares)
Total area:
432+162= 594 cm.²
I hope this makes more sense, have a great day :D

a car uses 32 L of gas to travel 450 KM. how many liters would be required to drive 800 km (to the nearest tenth)?
Answer: 56.88 L
Explanation:
Let L represents number of liters
A Car uses 32 L of gas to travel 450 km.
Write a proportion for the problem using rates.
450/32 = 800/L
Cross product is 450*L = 800*32
450L = 25600
Divide each side by 450.
450L/450 = 25600/450
L = 56.88

A company is making two types of covered aluminum containers. One is a cylinder with a height of 114feet and a diameter of 1 foot. The other is a rectangular prism with a length of 34foot, a width of 34foot, and a height of 1 foot. How much greater is a cylinder's capacity?
Answer:
[tex]V_d=976.9ft[/tex]
Step-by-step explanation:
From the question we are told that:
Height of cylinder h_1=114 feet
Diameter d=1
Length of triangular prism [tex]l_2=34ft[/tex]
Width of triangular prism [tex]w_2=34ft[/tex]
Height of triangular prism [tex]h_2=1 ft[/tex]
Generally the equation for Volume of the cylinder is mathematically given by
[tex]V_c=\pir^2h[/tex]
Where
[tex]r=d/2\\r=0.5[/tex]
Therefore
[tex]V_c-=\pi*0.5*114[/tex]
[tex]V_c=57\pi[/tex]
[tex]V_c=179.1ft[/tex]
Generally the equation for Volume of a Rectangular prism is mathematically given by
[tex]V_r=whl[/tex]
[tex]V_r=34*34*1[/tex]
[tex]V_r=1156feet[/tex]
Generally the equation for Volume difference is mathematically given by
[tex]V_d=V_r-V_c[/tex]
[tex]V_d=1156-179.1[/tex]
[tex]V_d=976.9ft[/tex]
Find the slope of the line that passes through the points (-6,6)and(4,-2).
Answer:
=-4/5
Step-by-step explanation:
To find the slope, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -2 -6)/(4 - -6)
= (-2-6)/( 4+6)
= -8/10
=-4/5
A Cylinder with
a volume of 27π
in 3 and a height
of 3 in. What is
the radius?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Surface Areas and Volume.
==> Volume of Cylinder = πr^2h
==> 27π = πr^2(3)
==> 27 = r^2 (3)
==> r^2 = 9
==> r = 3 inch
hence the radius is 3 inches.
