Answer:
Perpendicular
90 degrees
Step-by-step explanation:
When perpendicular lines intersect they form 4 right angles. Since these lines meet at 90-degree angles they must be perpendicular. Also, <ABC is directly across from <EBD, this means they are vertical angles. Vertical angles are congruent, so <EBD measures 90 degrees.

Bob made 4 1/4 pounds of fruit salad
10 ounces of pineapple.
as, 1 pound=16 ounces
So, 4 1/4=17/4= 4.25 pounds of fruit salad
Now, 4.25 pounds in ounce = 4.25* 16
= 68 ounces
Total serving = 68+10

10 students are competing in a dance competition. How many was can you award first, second, and third place?
Given:
Total number of students = 10
To find:
How many was can you award first, second, and third place?
Solution:
Total number of students is 10. So, the total possible ways for the first award is 10.
We know that one student can hold only one place. So, after giving the first award, the number of remaining students is 9 and the total possible ways for the second award is 9.
Similarly, the total possible ways for the third award is 8.
Now, the total number of ways to award first, second, and third place is:
[tex]10\times 9\times 8=720[/tex]
Therefore, the total number of ways to award first, second, and third place is 720.

A car dealership offers customers two pricing options for vehicle repair. Option 1: pay $80 per hour of wok. Option 2: pay a standard fee of $100 plus $400 per hour of work. What is the initial value and the rate of change for option 1
Answer:
1: The initial value for option one is not charged
The rate of change for option 1 is $80/hr
Step-by-step explanation:
1. From the pricing options at the car dealership we have;
Option 1
Initial value = Not stated
Fee rate per hour of work = $80
Option 2
Standard fee = $100
Fee rate per hour of work = $400
The initial value for option one is not charged
The rate of change = The increase in payment for each increase in one hour of work = $80/hour
Mathematically, we have;
[tex]The \ rate \ of \ change = \dfrac{\Delta Payment}{\Delta Time} = \dfrac{\$80 - \$0}{1 \, h- 0 \, h} = \$ 80/hr[/tex]
Find the value of x and each arc measure
Answer:
x = 11
m(arc)MN = 65
m(arc)NP = 115
m(arc)NQP = 245
Step-by-step explanation:
10x - 45 = 6x - 1
4x = 44
x = 11
m(arc)MN = 10x - 45 = 10(11) - 45 = 110 - 45 = 65
m(arc)NP = 180 - 65 = 115
m(arc)NQP = 360 - 115 = 245

The amount of possible paths to success is known as probability. the total number of outcomes that can occur.
Probability Calculation:Probability is the science of calculating or estimating how likely or 'probable' something will occur. A probability of an event occurring can be expressed using words such as "certain," "impossible," or "probable." Probabilities in mathematics always are expressed as fractions, decimals, or percentages with values ranging from 0 to 1.
For question 1:

A decade ago, 28% of high school students worked a part-time job during the school year. To investigate whether the proportion is greater today, a random sample of 80 high school students is selected. It is discovered that 37.5% of them work part-time jobs during the school year. The guidance counselor would like to know if the data provide convincing evidence that the true proportion of all high school students who work a part-time job during the school year is greater than 0.28.
The power of this test to reject the null hypothesis if p = 0.747 is 0.59 using a significance level of α = 0.05. What is the interpretation of the power of this test?
If the true proportion of high school students who work a part-time job during the school year is p = 0.747, there is a 0.59 probability that the guidance counselor will find convincing evidence for Ha: p > 0.28.
If the true proportion of high school students who work a part-time job during the school year is p = 0.747, there is a 0.59 probability that the guidance counselor will find convincing evidence for Ha: p = 0.28.

A jar contains "q" quarters and "d" dimes. There are 7 coins in the jar and the total value of the coins is $1.00

D. 25q + 10d = 1
q + d = 7
Answer:
A. 0.25q + 0.10d = 1.00
q + d =7
Step-by-step explanation: Only logical choice I see. The others mix up values and units.
The system of equations is
0.25q + 0.10d = 1.00
q + d =7
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
A jar contains "q" quarters and "d" dimes.
There are 7 coins in the jar and the total value of the coins is $1.00.
As, 2 quarters and 5 dimes
= 2(.25) + 5(.10)
= $.50+ $.50
= $1
Now, according to question,
0.25q + 0.10d = 1
and, 0.10q + 0.10d = 0.7
Solving above equation we get
0.15q = 0.3
q = 2 quarter

Answer:
[tex]y=-\frac{3}{4} x-4[/tex]
Step-by-step explanation:
When writing an equation of a line using slope-intercept form: y=mx+b, the slope of the line would take the place of m, and the y-intercept would take the place of b. Just substitute these variables for the slope and y-intercept to find the equation of the line.
lmk if this is incorrect, hope it helps!!
Answer:
y= -3/4x-4
Step-by-step explanation:
This is assuming that you want it in slope-intercept (y=mx+b)
You need to know that
Y= The line
m=Slope
b=y-intercept
Step 1, Replace slope (m)
y= -3/4x+b
Step 2, Replace the y-intercept
y= -3/4x-4
Conclusion to 'what is the equation of the line if its slope is -3/4 and Y-intercept is -4': y= -3/4x-4
One of the legs of a right triangle measures 7 cm and the other leg measures 3 cm.
Find the measure of the hypotenuse. If necessary, round to the nearest tenth.
Answer:
about 7.6
Step-by-step explanation:
I got the measure of the hypotenuse to be about 7.6 because I did the Pythagorean theorem.
a^2+b^2=c^2
The value of a is the first leg (7cm), and the value of b is the second leg (3cm).
So, 7^2+3^2=58. Next, I found the square root of 58. The square root of 58 is 7.615773106. This value rounded to the nearest tenth is 7.6.
In conclusion, the measure of the hypotenuse rounded to the nearest tenth is about 7.6.
