Rodrigo practiced playing the guitar 15 1/3 hours over the past 3 weeks.
He practiced for 5 1/4 hours during the first week and 5 2/3 hours during the second week.
How much time did Rodrigo spend practicing during the third week? Use the numbers and symbols to select the equation that represents the problem. Then solve the equation. Symbols may be used more than once or not at all.
15 1/3, 5 1/4, 5 2/3, x, =, and +.

The equation that represents the problem is
a. 15 1/3 = x - 5 1/4 - 5 2/3
b. x = 15 1/3 + 5 1/4 + 5 2/3
c. x + 15 1/3 = 5 1/4 + 5 2/3
d. 15 1/3 = 5 1/4 + 5 2/3 + x

Answers

D, because we already know how much he spent in total so it isnt B, trust me its D

Answer: d. 15 1/3 = 5 1/4 + 5 2/3 + x

Step-by-step explanation:

15 1/3 (total) = 5 1/4 (first week) +5 2/3 (second week) +x (third week)

When you add the amount of time Rodrigo practiced each week, you get the total amount of time he practiced

(10, y) and (3, 4); m= - 2/7

Answers

Answer:

y = 2

Step-by-step explanation:

use slope formula:

(4 - y) / (3 - 10) = -2/7

4-y / -7 = -2 /7

cross-multiply:

7(4 - y) = (-7)(-2)

28 - 7y = 14

-7y = -14

y = 2

IMPORTANT!! in a unit circle, what is the relationship between arc length and central angle?

Answers

The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.

Write a polynomial in standard form that represents the area of the shaded region.

Answers

Answer:

Area of the smaller square is x * x, which is x^2

Area of the larger square is (x + 7)(x + 7), which is x^2 + 14x + 49

The area of the shaded area = Area of the larger square - Area of the smaller square

Area of the shaded region = x^2 + 14x + 49 - x^2

Area of the shaded region is 14x + 49.

Celia used celery, carrots, and tomatoes in a recipe. Use the clues to find the amount of each ingredient she used. CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup. CLUE 2: There is less celery than tomatoes. CLUE 3: There is less tomatoes than carrots.

Answers

Answer:

Celery = 3/8 cups

Tomatoes = 2/5 cups

Carrot = 5/4 cups

Step-by-step explanation:

CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup

CLUE 2: There is less celery than tomatoes.

CLUE 3: There is less tomatoes than carrots

From clue 2 and 3:

Tomato > Celery ; Carrots > tomatoes

From least to highest :

Celery < Tomatoes < Carrot

Arranging clue 1 in ascending order :

2/5 = 0.4

3/8 = 0.375

5/4 = 1. 25

Hence,

3/8 < 2/5 < 5/4

Celery = 3/8 cups

Tomatoes = 2/5 cups

Carrot = 5/4 cups

A shop makes £2,750 in March. It has an Easter sale and the profit for April is £3,162.50 Work out the percentage increase

Answers

Answer: 15%

Step-by-step explanation:

From the question, we are informed that a shop makes £2,750 in March while it made £3,162.50 in April. The increase will be:

= £3,162.50 - £2,750

= £412.50

Percentage increase = £412.50/ £2750 × 100

= 15%

Step-by-step explanation:

⅕m - 12 = -32
could someone solve this

Answers

Answer:

m = -100

Step-by-step explanation:

(1/5)m -12 = -32

add 12 on both sides

(1/5)m = -20

multiply both sides by 5

m = -100

Answer:

m = -100

Step-by-step explanation:

So in order to solve this equation we are going to have to convert 1/5m to a decimal, this will make it easier to solve the equation:

1/5m = 0.2m

Next we are going to take our 0.2m and place it within the equation where 1/5m is:

⅕m - 12 = -32  or 0.2m - 12 = -32

So now we are going to add 12 to both sides of the equal sign in the equation to segregate the 0.2m within the equation:

0.2m - 12 = -32  or 0.2m + (-12 + 12) = (-32 + 12)

making the equation look like this:

0.2m = -20

now we are going to divide 0.2 from both 0.2m and -20 to get the value of m:

0.2m/0.2 = -20/0.2

Thus getting the answer:

m = -100

So how do we know that -100 is the value of m? well we check our work of course by substituting -100 in place of m!

⅕(-100) - 12 = -32  or 0.2(-100) - 12 = 32

0.2(-100) - 12 = 32

-20 - 12 = -32

-32 = -32

What is the interest rate of the account? What is the balance after 10 years?

Answers

Answer:

The interest rate is $2, the balance after 10 years will be $60.

Step-by-step explanation:

Each year the balance of the account increases by $2, so that would be the interest rate. After 10 years, the account will have 40 + 2 * 10 which equals $60.
