Answer:
x = [tex]\sqrt{30}[/tex]
Step-by-step explanation:
Applying altitude- on - hypotenuse theorem.
(leg of large Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 3 × (3 + 7) = 3 × 10 = 30 ( take square root of both sides )
x = [tex]\sqrt{30}[/tex]

Lucy maybe a pumpkin pie to sell at the bake sale. She cut it into 6 slices and sold each slice for $1.25. How much money will she sell the entire pie?
Answers
Answer: She will sell the entire pie for $7.5.
Step-by-step explanation:
Given: Number of slices in each pumpkin pie = 6
Selling price for each slice = $1.25
Now , Selling price for 6 slices = 6 x (Selling price for each slice)
= 6 x $1.25
= $ 7.5
i.e. Selling price for entire pie = $ 7.5
Hence, She will sell the entire pie for $7.5.

The liver filters the drug Tylenol in an exponential way. Suppose tests show that after 12 hours pass, since taking a does of 400 milligrams, 50 milligrams remain in the blood stream. What is the half life of of Tylenol?
Possible answers:
6.5 hours
4 hours
No correct answer
Answers
9514 1404 393
Answer:
4 hours
Step-by-step explanation:
There are several ways to work this. One way that often works well with multiple choice questions is "try the answers".
6.5 hours
If the half-life is 6.5 hours, then 200 mg will remain after 6.5 hours, and 100 mg will remain after 13 hours. The decay rate is faster than that, so 6.5 hours is not right, but a lesser value is.
4 hours
If the half-life is 4 hours, then 200 mg will remain after 4 hours, and 100 mg will remain after 4 more (=8) hours. An additional 4 hours will cut that in half again to 50 mg after 12 hours.
The half-life is 4 hours.

What is the equation on the line on this graph?
Answers
Answer:
y = 1
Step-by-step explanation:
Slope = 0 since it is a horizontal line.
y = mx + b is your slope intercept form.
m = slope
b = y-intercept
find b. in other words, when x = 0. We see that when x = 0, y = 1. Therefore, your b = 1.
put together your equation
y = mx + b
y = 0x + 1
therefore, y = 1 is your equation for the line on the graph

The balance in her check register will be $58 under the balance on her bank statement. C. The balance in her check register will be $58 over the balance on her bank statement. D.

Answers
The correct Statement is C) The balance in her check register will be $58 over the balance on her bank statement.
What Is a Bank Statement?A bank statement is a document (also known as an account statement) that is typically sent by the bank to the account holder every month, summarizing all the transactions of an account during the month. Bank statements contain bank account information, such as account numbers and a detailed list of deposits and withdrawals.
Given here: Kimberley accidentally recorded $58 bill in the credit section in her check register.
Thus the bank statement will read balance as $58 less than her register which accounted accidentally the bill in the credit section in instead of debit.
Hence, C) The balance in her check register will be $58 over the balance on her bank statement. is the final answer.

The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3 8 of the items barbecued are veggie burgers, and 1 3 of the items barbecued are corn cobs, what fraction of barbecued items are mushroom caps? 17 24 4 11 3 8 1 8 7 24
Answers
Answer: 7/24
Step-by-step explanation:
Fraction of the items barbecued that are veggie burgers = 3/8
Fraction of the items barbecued that are corn cobs = 1/3
The fraction of the items barbecued that are mushrooms caps will be:
= 1 - (3/8 + 1/3)
The lowest common multiple of 8 and 3 is 24.
= 1 - (3/8 + 1/3)
= 1 - [(3/8 × 24) + [(1/3 × 24)]
= 1 - (9/24 + 8/24)
= 1 - 17/24
= 7/24

Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother. What percent of the baseball cards did he give to his brother?
Answers
Answer:
85%
Step-by-step explanation:
Evan had 120 baseball cards. He gave 18 of them to his friend and the rest to his brother.
The number of baseball cards he gave to his brother is :
120 - 18 = 102 baseball cards
The percent of the baseball cards he gave to his brother is calculated as:
(Number of baseball cards given to his brother/ Total number of baseball cards) × 100
= 102/120 × 100
= 85%
The percent of baseball cards Evans gave his brother is 85%

Two sailboats are traveling along the same path away
from a dock, beginning from different locations at the
same time. John's boat begins 20 miles from the dock and
is 55 miles from the dock after 5 hours. The distance of
Roberta's boat from the dock is represented by the
function y= 6x + 10, where x represents time and y
represents the distance from the dock.
Which boat was farther from the dock at the beginning, and which traveled
more quickly?
O A. Roberta's boat was farther from the dock at the beginning, but
John's boat trzeled more quickly
B. John's boat was farther from the dock at the beginning, and it

What is distance?Distance is a numerical measurement of how far apart objects or points
What is Speed?The speed of an object is the magnitude of the rate of change of its position with time or the magnitude of the change of its position per unit of time
At beginning John's boat was 20 miles from dock
After 5 hours its was 55 miles form the dock
Speed of the boat = Distance / Time
Speed = [tex]\frac{55-20}{5}[/tex]= 7 miles per hour
Robert boat is represented by the function
y=6x+10
at starting x=0
y = 10 miles away from the dock
After 5 hours x=5
y = 6×5+10
y=40 miles away from the dock
Speed of the Robert's boat = [tex]\frac{40-10}{5}[/tex]
Speed = 6 miles per hour
Hence, The boat was farther from the dock at the beginning, and which traveled more quickly is option is B John's boat was farther from the dock at the beginning and it traveled more quickly
