Answer:
x = 3 ; y = 30
Step-by-step explanation:
Δ is equilateral or equiangular ⇒ m∠A = m∠B = m∠C = 60°
(2y)° = 60° ⇒ y = 30
(25x - 15)° = 60° ⇒ x = 3

Which sentence has modifiers in the right place to make its meaning clear?
A.
Every year, we bought a homemade apple pie at a little store that cost only $5 on the road to the cabin.
B.
Every year, we bought a homemade apple pie that cost only $5 at a little store on the road to the cabin.
C.
Every year, we bought a homemade apple pie at a little store on the road to the cabin that cost only $5.
Answers
The correct answer is B. Every year, we bought a homemade apple pie that cost only $5 at a little store on the road to the cabin.
Explanation:
In the sentences presented the section "that cost only $5" is a modifier because this describes the noun "homemade apple pie". Moreover, this modifier should be placed right after the noun it describes to clarify the "$5" refer to the cost of the pie.
This occurs in option B "a homemade apple pie that cost only $5" because this places the modifier after the noun, and this makes the sentence to be clear. On the other hand, in other options the meaning is confusing. For example in A "a homemade apple pie at a little store that cost only $5," it is not clear if the cost refers to the apple or the store.

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 50 nails and each large box has 350 nails. The contractor bought 5 more large boxes large boxes than small boxes, which altogether had 2550 nails. Determine the number of small boxes purchased and the number of large boxes purchased.
Answers
Answer:
Number of small boxes purchased : 2
Number of large boxes purchased : 5
Step-by-step explanation:
Let,
x be the number of small boxes of nails purchased
y be the number of large boxes of nails bought
Then according to given statement;
50x+350y = 2550 Eqn 1
y = x+5 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
50x + 350(x+5) = 2550
50x + 350x + 1750 = 2550
400x = 2550-1750
400x = 800
Dividing both sides by 400
[tex]\frac{400x}{400}=\frac{800}{400}\\x=2[/tex]
Putting x=2 in Eqn 2
y = 2+5
y = 7
Hence,
Number of small boxes purchased : 2
Number of large boxes purchased : 5

In 1998, Hurricane Bonnie approached the United States at a speed of 8 miles per hour. The function y = 8x describes how many miles y Hurricane Bonnie traveled x hours. Use the graph to estimate how far the hurricane traveled in 2.5 hours.
Answers
Answer:
20 miles
Step-by-step explanation:
Given the equation of the line of the graph, y = 8x, where,
y = distance the hurricane travelled in miles
x = time of travel in hours
8 = slope/speed in miles/hour
To find how far the hurricane travelled in 2.5 hours, substitute x = 2.5 into y = 8x
This:
y = 8(2.5)
y = 20 miles
Thus, from the graph, we can estimate this also. On the x-axis, between 2 and 3, we have 2.5 hours. The corresponding value of x = 2.5 is y = 20.

What does it mean to be sad and lonely
Answers
Answer: It means depression
Step-by-step explanation:
Answer:
Being sad means your body has entered a mini-clinical state, bringing back grief and usually making you remember past traumas for no existential reason. Sadness can drive you to feeling alone - not isolated, but alone with your inner thoughts. Your interior feeling cold, and like no one is there to put their hand out and help you become warm again. Sadness can drive you to loneliness, and loneliness can lead you to depression. Depression inverts your brain waves and makes you feel useless, no-good, nothing useful, just a joke.

The school band decided to make pizza kits to sell for their fundraiser.
The materials cost them $
1500, and they sold the pizza kits for $8.50 a
kit. The Function below can be used to find the profit p(x), where x is
the nunuer of kits sold.
P(x) = 8.50x- 1500
If the band made a profit of $2920, how many pizza kits were sold?
a. 167 kits
b. 344 kits
C. 402 kits
d. 520 kits
Answers
Answer:
520
Step-by-step explanation:
Given that:
Profit function p(x) is :
P(x) = 8.50x- 1500
If the profit made = $2920 ; the number of pizza kits sold is :
Then p(x) = 2920
Putting p(x) = 2920 in the equation :
2920 = 8.50x - 1500
2920 + 1500 = 8.50x
4420 = 8.50x
Divide both sides by 8.50
4420 / 8.50 = 8.50x / 8.50
520 = x
Hence, number of pizza kits sold is 520
