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?

Answers

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

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?

Answers

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

Leah is sending out 32 party invitations. She gives 5 invitations to her Mom to give to family members. Leah mails a third of the rest. Write a numerical expression to describe how many invitations Leah has already mailed.

Answers

Answer:

9 of 32 invitations were mailed

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.

The numerator is the number above. While the denominator is the number below

Write and solve an equation to find the value of x and a missing angle in the triangle below.

Answers

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°

Given the Trapezoid ABCD

Find the length of AD

Pls hellpppp

Answers

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.
