∠A and \angle B∠B are supplementary angles. If m\angle A=(7x+10)^{\circ}∠A=(7x+10) ∘ and m\angle B=(7x-26)^{\circ}∠B=(7x−26) ∘ ,

Answer:

108 degrees

Step-by-step explanation:

Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:

Combine like terms: 14x - 16 = 180

Add 16 to both sides: 14x = 196

Divide both sides by 14: x = 14

Now that you know x, you can plug it into the expression for angle A (7x+10):

A = 7(14) + 10 = 98+10 = 108

58:49 A pound of raisins costs $2.00, and a pound of almonds costs $5.00. Six pounds of a trail mix contains 2 more pounds of ra

faltersainse [42]

Answer:

$18

Step-by-step explanation:

1 pound of raisins = $2

1 pound of almonds = $5

Let the number of raisins be represented by a

Let the number of almonds be represented by b

We are told in the question that:

Six pounds of a trail mix contains 2 more pounds of raisins than almonds.

a + b = 6 pounds

Hence, Almonds = 2 pounds

Raisins = 4 pounds

The cost of the 6 pounds of trail mix

= 4 × $2 + 2 × $5

=$8 + $10

= $18

A circular window is surrounded by a circular frame. The radius of the window is m - 2 and the radius of the full circle formed

Vesnalui [34]

Answer:

Correct answer is: A = 8 m π

Step-by-step explanation:

In fact, it is necessary to calculate the surface of the circular ring representing the circular window frame:

It's formula:

A = (R² - r²) π where R = m + 2 and r = m - 2

A = ((m + 2)² - (m - 2)²) π = (m + 2 + m - 2) (m + 2 - m +2) π = 2m · 4 π

A = 8 m π

Sherri currently has an account balance of $1,050.80. Her initial deposit on the account was $740 and it earned 3.5% simple inte

Yanka [14]

Answer:

<u>Sherri has the account since twelve years ago</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Current balances of Sherri's account = $ 1,050.80

Initial deposit = $ 740

Interest rate = 3.5% simple interest = 0.035

2. How long has Sherri held the account?

Let's recall the formula of the simple interest:

FV = P * (1 + rt), where FV is the future value of the investment or initial deposit, P, the initial deposit, r, the interest rate and t, the number of periods.

Replacing with the values we have:

1.050.80 = 740 * (1 + 0.035t)

1,050.80 = 740 + 25.9t

1,050.80 - 740 = 25.9t

310.80 = 25.9t

t = 310.80/25.9

t = 12
