Pam has $60,000 in a savings account that earns 11% interest per year. The interest is not compounded. How much interest will she earn in 8 months?
Answer:
The amount of interest is $4,400
Step-by-step explanation:
To get the amount of interest, we use the simple interest formula
Mathematically;
I = PRT/100
I = interest
P is the amount deposited = $60,000
R is interest rate = 11%
t is time in years = 8/12 = 2/3
Substituting these values, we have
I = (60,000 * 11 * 2/3)/100
I = $4,400

When a bakery opened this morning, the ratio of the number of pineapple muffins to the number of mango muffins was 3 : 2. After 244 pineapple muffins were sold, the ratio of the number of pineapple muffins to the number of mango muffins changed to 3 : 5. How many pineapple muffins were there when the bakery opened this morning?
Answer:
(x+244)/y=3/2
x/y=3/5
y=5x/3
(x+244)/(x5/3)=3/2
x+244=3/2 . 5x/3
x+244=15x/6
6(x+244)=15x
6x+1464=15x
1464=15x-6x
1464=9x
x=1464/9
x≈ 162
mm=162*5/3=270
162:270 = 3:5
pm before = 270*3/2=405
405:270 = 3:2
Write and solve an equation to find the value of x and a missing angle in the triangle below.
Answer:
x = 27°, ∠JLK = 55°
Step-by-step explanation:
From the diagram in the question above,
The exterior angle of a triangle is equal to the sum of the two opposite side
3x+13 = 39+(2x+1)
3x+13 = 40+2x
collect like terms and solve for x
3x-2x = 40-13
x = 27°.
∠JKL = 2x+1
Substitute the value of x
∠JKL = 2(27)+1
∠JKL = 54+1
∠JKL = 55°

Determine the distance between (−3,1)and (5,−6)
Round your answer to the nearest tenth. Show all of your work.
Answer:
10.6 units
Step-by-step explanation:
distance formula
= √((x2-x1)²+(y2-y1)²)
= √((5+3)²+(-6-1)²
= √(8²+(-7)²)
= √ (64+49)
= √113

Primary school students are playing hide and seek at recess as the counting begins Jon runs 100 feet east , turns 45 degrees north of east and runs another 120 feet to find a hiding spot . Lisa finds her hiding spot by running 120 feet west , turning 32 degrees south of west , and continuing another 100 feet which students hiding spot is closer to starting point ?
Answer:
Jon's hiding spot is closer to the starting point.
Step-by-step explanation:
Jon's final position forms a triangle with sides 100 ft and 120 ft respectively with an angle of 180 - 45 = 135 between them. Since the angle between the 100 ft direct east and 120 ft direction is 45, since Jon turns 45 after moving for 100 ft and then moves another 120 ft to his final destination.
Also, Lisa's final position forms a triangle with sides 120 ft and 100 ft respectively with an angle of 180 - 32 = 148 between them. Since the angle between the 120 ft direction west and 100 ft direction south of west is 45, since Lisa turns 32 after moving for 120 ft and then moves another 100 ft to her final destination.
Using the cosine rule,
a² = b² + c² - 2abcosФ, we find the length of the third side of each triangle which is their distance from the starting point.
So, for Jon
a² = b² + c² - 2abcosФ where b = 100 ft, c = 120 ft and Ф = 135°
Thus,
a² = (100 ft)² + (120 ft)² - 2(100 ft)(120 ft)cos135°
a² = 10000 ft² + 14400 ft² - 24000 ft²cos135°
a² = 10000 ft² + 14400 ft² - 24000 ft²(-0.7071)
a² = 24400 ft² + 16970.56 ft²
a² = 41370.56 ft²
a = √(41370.56 ft²)
a = 203.4 ft
for Lisa
a'² = b'² + c'² - 2a'b'cosФ' where b = 120 ft, c = 100 ft and Ф = 148°
Thus,
a'² = (120 ft)² + (100 ft)² - 2(120 ft)(100 ft)cos148°
a'² = 14400 ft² + 10000 ft² - 24000 ft²cos148°
a'² = 14400 ft² + 10000 ft² - 24000 ft²(-0.8481)
a'² = 24400 ft² + 20353.15 ft²
a'² = 44753.15 ft²
a' = √(44753.15 ft²)
a' = 211.56 ft
a' ≅ 211.6 ft
Since a = 203.4 ft < a' = 211.6 ft,
Jon's hiding spot is closer to the starting point.

Jill is baking an apple pie. She cuts each apple into rectangular prism pieces and length 1 inch, width 1/4 inch, and height 1/2 inch. In total, she cuts 528 apple slices. What is the volume of each slice? What is the volume of all of the cut apples?
Step-by-step explanation:
Area of Rectangle Prism = Area of base x height
= Length x Width x Height
[tex] = 1 \times \frac{1}{4} \times \frac{1}{2} \\ = 0.125 {in}^{3} [/tex]
One Apple Pie =
[tex]0.125 {in}^{3} [/tex]
Volume of 528 Apple Pies = Volume of 1 apple pie x 528
=
[tex]0.125 \times 528 \\ = 66 {in}^{3} [/tex]
Given the Trapezoid ABCD
Find the length of AD
Pls hellpppp
Given:
In trapezoid [tex]ABCD, AD\parallel BC, MN[/tex] is the mid-segment of [tex]ABCD, AD=30x-10,MN=31x+1,BC=30x+28[/tex].
To find:
The length of [tex]AD[/tex].
Solution:
We know that the length of the mid-segment of a trapezoids is half of the sum of lengths of two parallel sides of the trapezoid.
In trapezoid [tex]ABCD[/tex],
[tex]MN=\dfrac{AD+BC}{2}[/tex]
[tex]31x+1=\dfrac{30x-10+30x+28}{2}[/tex]
[tex]31x+1=\dfrac{60x+18}{2}[/tex]
[tex]31x+1=30x+9[/tex]
Isolate variable terms.
[tex]31x-30x=9-1[/tex]
[tex]x=8[/tex]
Now,
[tex]AD=30x-10[/tex]
[tex]AD=30(8)-10[/tex]
[tex]AD=240-10[/tex]
[tex]AD=230[/tex]
Therefore, the length of [tex]AD[/tex] is 230.

A side of the triangle below has been extended to form an exterior angle of 156°. Find
the value of x.
Answer:
24°
Step-by-step explanation:
156° and x° form a straight line, and angles that form a straight line sum to 180°
Thus, 156° + x° = 180°
=> x° = 180° - 156° = 24°
Explain why a + b = d.

fraction = 9/32
Decimal = this can be derived by dividing 9 by 32 = 0.28
Percentage = this can be derived by multiplying the decimal by 100 = 28%
Step-by-step explanation:
Number of invitations mailed = 1/3 x (total invitation - invitation mom delivered)
1/3 x (32 - 5)
1/3 x (27)
= 9
This figure can be expressed as a fraction
A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.
