Answer:

54°

Step-by-step explanation:

∠A = 2x + 10, ∠C = 3x - 14

∠E + 266 = 360 (sum of angles around a point)

∠E = 360 - 266

∠E = 94°

AB is parallel to line BD. Lets draw a line cuts line AB and line BD to form ∠B and ∠D. Hence:

∠B + ∠D = 180° (sum of interior angles on the same side)

∠A + ∠B + ∠C + ∠D + ∠E = 540° (sum of angles in a pentagon)

2x + 10 + 3x - 14 + 94 + 180 = 540

5x + 270 = 540

5x = 540 - 270

5x = 270

x = 54°

2x + 3y = -10
5y = 4x - 2

Find the smallest possible integer value of k for which 264k is a perfect square.

Answers

Step-by-step explanation:

264k

= 2³ * 3 * 11 * k

Hence, k = 2 * 3 * 11 = 66.

Answer:

k = 66.

Step-by-step explanation:

Find the prime factors of 264

264  =  2 * 2 * 2 * 3 * 11

The nearest perfect square will contain  one more 2, one more 3 and one more 11

=  264 * 2 * 3 * 11

Answer: Choice C

x+y = 28

3x+4y = 100

===================================================

Explanation:

x and y are placeholders for nonnegative whole numbers.

Specifically,

x = number of three point questions

y = number of four point questions

Since we have 28 questions total, this must mean x+y = 28. That forms the first equation in our system of equations.

------------

Now let's form the second equation:

x = number of three point questions

3x = points we get from all the three point questions

y = number of four point questions

4y = points we get from all the four point questions

3x+4y = all points possible

3x+4y = 100  is the second equation

------------

So we have this system

[tex]\begin{cases}x+y = 28\\3x+4y = 100\end{cases}[/tex]

which fits the conditions in the instructions.

A business trip will be reimbursed $0.55 per mile. Mr. Jackson has a budget of $70 for the round trip. If he is traveling to a town 61 miles away, then will he be under or over? Prove your thinking.

Answers

Answer:

We know Mr. Jackson will have to pay 0.55 dollars per mile and that he's traveling 61 miles, so, if we want to know. how much will he pay, we can multiply the quantity of miles (61) per the cost of these:

0.55 * 61 = 33.55

So we know he will have to pay 33.55 dollars, and, as the travel is round, considering he will travell the same quantity of miles, he will pay twice

33.55 * 2 = $67.10

He has more budget than the needed for the travel

Answer:

Mr. Jackson will be under his budget.

Step-by-step explanation:

We know that Mr. Jackson has a budget of only $70 for the trip. We know that the trip will be reimbursed $0.55 per mile. Mr. Jackson is traveling 61 miles. Therefore, we need to multiply $0.55 by 61.

61 x 0.55 = $35.55

Since $35.55 is less than $70, he will be under his budget.

1. 3 cans of pudding costs $2.48 at Store A and 6 cans of the same pudding costs $4.50 at Store B. Which store has the better buy on these cans of pudding?

Answers

Answer:a

Step-by-step explanation:

Answer:

Store B because if you take 2.48 divided by 3 to figure out the cost per can aka one can  it will be 0.826 repeating and that's for store A . While store B you take 4.5 divided by 6 to and get 0.75 per can so Store B is the best option since 0.75 is smaller than 0.826.

The temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer. It may reach a low of -225 degrees Fahrenheit at the poles. Which expression gives the difference between those temperatures?

Answers

Answer: See explanation

Step-by-step explanation:

Since we are informed that the temperature on Mars may reach a high of 70 degrees Fahrenheit at the equator in the summer and may also reach a low of -225 degrees Fahrenheit at the poles.

The expression that gives the difference between those temperatures would then be calculated as:

= 70°F - (-225°F)

= 70°F + 225°F

= 295°F
