Help!! I only have 20 minutes!!!!!

Answer:

4/7 of her total time cleaning the kitchen

Step-by-step explanation:

Olivia does chores every Saturday morning. She spends 1/3 of her time cleaning her room. Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?]

Let

x = her total time

Room cleaning = 1/3x

Time remaining = 2/3x

Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen.

Kitchen cleaning = 6/7 of 2/3x

= 6/7 * 2/3x

= (6*2)x/(7*3)

= 12/21x

= 4/7x

Olivia spent 4/7 of her total time cleaning the kitchen

Step-by-step explanation:

new height is ¼ of original height

new width = ¼×8 = 2 inches

Answer:

2 inches

Step-by-step explanation:

To find the new width, find the scale factor that was used to reduce the photo.

Since 16 divided by 4 is 4, 4 is the scale factor.

To find the new width, divide 8 by 4:

8/4

= 2

So, the new width is 2 inches

Answer:

1564.

Step-by-step explanation:

First term = -28 and common difference = 15.

Sum = (17/2)(2*-28 + (17-1)15)

= 8.5 * 184

= 1564.

Answer:

  97.42 square units

Step-by-step explanation:

The area of a sector is given by ...

  A = (1/2)r²θ

where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.

  75° = (75°)×(π/180°) radians = (5/12)π radians

Then the area is ...

  A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units

__

Equivalently, you can find the area of the circle in the usual way:

  A = πr² = π(12.2²) ≈ 467.59465

Then, multiply by the fraction of the circle that is shaded (75°/360°)

  sector area = (467.59465)(75/360) = 94.42 . . . square units

Answer:

1,100

Step-by-step explanation:

Wow that's a lot of students. Anyway, 25% is one fourth of the 100%, so we multiply 275 by 4 and we get 275.

Answer:

60 meters, see explanation.

Step-by-step explanation:

We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.

You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.

Solve the system of equations using the substitution method. Show all works

⠀ ⠀⠀

⠀ ⠀⠀

⠀ ⠀⠀

⠀ ⠀⠀

From equation (i), we have :

[tex] \tt : \implies y = 5x - 7[/tex]

⠀ ⠀⠀

By Substituting y = 5x - 7 in equation (ii), we get :

[tex] \tt : \implies - 3x - 2(5x - 7) = - 12[/tex]

[tex] \tt : \implies - 3x - 10x + 14 = - 12[/tex]

[tex] \tt : \implies - 13x = - 12 - 14[/tex]

[tex] \tt : \implies - 13x = - 26[/tex]

[tex] \tt : \implies 13x = 26[/tex]

[tex] \tt : \implies x = \dfrac{26}{13}[/tex]

[tex] \tt : \implies x = 2[/tex]

[tex] \large \underline{\boxed{\bf{x = 2}}}[/tex]

⠀ ⠀⠀

Now, By substituting x = 2 in equation (i), we get :

[tex] \tt : \implies y = 5(2) - 7[/tex]

[tex] \tt : \implies y = 10 - 7[/tex]

[tex] \tt : \implies y = 3[/tex]

Answer:

Step-by-step explanation:

First find the profit they will make from each shirt:

= Selling price - Cost price

= 12 - 10

= $2

They need to cover the cost of setting up which is $130. The number of shirts to sell given a profit of $2 from each shirt is:

= 130 / 2

=65 shirts

Cost of selling 65 shirts:

= 65 * 10 per shirt

= $650

Answer:

11/3 times 6/7 is 3.14 not sure how to solve it but hope this helps

Step-by-step explanation:

The Answer is 46

The measure of Arc PRQ is 268. Another part of the arc is PQ. PRQ+PQ forms a full circle In which a circle has 360 degrees. Using that

[tex]268 + x = 360[/tex]

[tex]x = 92[/tex]

Since we are asked to the measure of PRQ and it is inscribed in arc PQ. It is half of PQ so the answer is

[tex]92 \div 2[/tex]

which is 46.

Answer:

3

Step-by-step explanation:

Given

f(x) = - 3x + 5

f(x) = - 4

-3x + 5 = - 4

- 3x = - 4 - 5

- 3x = - 9

x = 3

Hope it will help :)

Answer:

x=3

Step-by-step explanation:

i believe it's like this, i am not sure

Y= -3x +5

-4= -3x+5

subtract 5 on both sides

-9= -3x

divide -3 on both sides

x=3

Answer:

Step-by-step explanation:

3. 10x + 6 = 8x

   8x = 10x + 6

   -2x = 6

  x = -3

4. y = 8(1) - 5= 8 - 5 = 3

   y = 8(2) - 5 = 16 - 5 = 11

    y = 8(5) - 5 = 40 - 5 = 35

    y = 8(0) - 5 = 0 - 5 = -5

    y = 8(-1) - 5 = -8 - 5 = -13

[tex]10x + 6 = 8x[/tex]

[tex]6 = 8x - 10x[/tex]

[tex]6 = - 2x[/tex]

[tex]6 \div - 2 = x[/tex]

[tex] - 3 = x[/tex]

[tex]y = 8x - 5[/tex]

When [tex] x = 1, y = \bold{ 3} [/tex]

[tex]y = (8 \times 1)- 5[/tex]

[tex]y = 8 - 5[/tex]

[tex]y = 3[/tex]

When [tex] x = 2, y = \bold{ 11} [/tex]

[tex]y = (8 \times 2)- 5[/tex]

[tex]y = 16 - 5[/tex]

[tex]y = 11[/tex]

When [tex] x = 5, y = \bold{35} [/tex]

[tex]y = (8 \times 5)- 5[/tex]

[tex]y = 40 - 5[/tex]

[tex]y = 35[/tex]

When [tex] x = 0, y = \bold{-5} [/tex]

[tex]y = (8 \times 0)- 5[/tex]

[tex]y = 0 - 5[/tex]

[tex]y = - 5[/tex]

When [tex] x = -1, y = \bold{-13} [/tex]

[tex]y = (8 \times - 1)- 5[/tex]

[tex]y = - 8 - 5[/tex]

[tex]y = - 13[/tex]

Answer:

Interest wil be 10% of 100  which is 10

So,  interest will be Rs.10

And total amount to be payed will be 100+10 which is Rs.110

Answer:

Interest= Rs. 10

Step-by-step explanation:

Interest of Rs.100 on 10 p.c.p.a is 10% of 100

i.e., 100*10/100 = 10

Thus we have 10 as the interest

Step-by-step explanation:

Answer:

Rs. 451.2

Step-by-step explanation:

It is given that a men's total taxable income is Rs. 14,280.

He is charged by the state tax for 2% on the first Rs. 3000.

i.e. [tex]$2 \% \times 3000$[/tex]

   [tex]$=\frac{2}{100} \times 3000$[/tex]

  = Rs. 60

Then he is asked to pay 3% on the second Rs. 3000

i.e. [tex]$3 \% \times 3000$[/tex]

   [tex]$=\frac{3}{100} \times 3000$[/tex]

  = Rs. 90

Similarly, he pays 3% on the third Rs. 3000

i.e. [tex]$3 \% \times 3000$[/tex]

   [tex]$=\frac{3}{100} \times 3000$[/tex]

  = Rs. 90

Lastly, he pays 4% on the remaining amount. i.e 14,280 - (3000+3000+3000) = 14,280 - 9000 = Rs. 5280

∴[tex]$4 \% \times 5280 $[/tex]

   [tex]$=\frac{4}{100} \times 5280$[/tex]

  = Rs. 211.2

Thus the total amount of the income tax the man has to pay is

= 60+90+90+211.2

= Rs. 451.2

Step-by-step explanation:

Answer:

2,548

Step-by-step explanation:

First, we have to find out the rule. The rule is multiply the previous number by 3 to get the next number.

7x3=21

21x3=63

So, we would continue this pattern until we have the first 6 numbers which are 189, 567, and 1701.

The questions is asking for the SUM of the 6 numbers so you would add the those numbers and do this equation:

7+21+63+189+567+1701= 2548
