Answer:
< EFD = 47.5 degrees.
Step-by-step explanation:
Use the theorem that tells us that the central angle <ECD is twice the angle EFD. and therefore the angle <EFD must be 95/2 = 47.5 degrees.
This agrees with the third option of the answer list.
The measure of angle EFD in the given image is equal to 47.5 degrees.
To find the measure of angle EFD, use the following formula:
The measure of an inscribed angle is always half the measure of the arc it intercepts.
m∠EFD = m∠ECD /2
where,
m∠EFD is the measure of angle EFD
m∠ECD is the measure of central angle ECD
Here, we have:
m∠ECD is equal to arc length as it is inscribed angle
This implies
m∠ECD =
m∠EFD = m∠ECD/2
= 95/2
= 47.5 degrees
Therefore, the measure of angle EFD is 47.5 degrees.

PLEASE HELP
Answers
B. Engine Repair is more likely to be paid for with a credit card. Option B is correct
It is to be determined Which of these purchases is more likely to be paid for with a credit card
Parking fee B. Engine repair C. Soda D. Lotto ticket
A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.
Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.
Thus, B. Engine Repair is more likely to be paid for with a credit card. Option B is correct

Which equation is equivalent to 10x+15y=−90 when it is solved for y? y=−23x−6 y=23x−6 y=−32x−6 y=32x−6
Answers
Answer:
Step-by-step explanation:
10x + 15y = -90
15y = -10x - 90
y = (-10/15)x - 90/15 = -⅔x - 6
The required equation is -(2/3)x - 6 which is equivalent to the given equation 10x + 15y = −90, which is the correct answer that would be option (A).
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
The equation is given in the question
10x + 15y = -90
We have to determine whether the equation is equivalent to 10x+15y=−90 when it is solved for y
As per the given equation,
⇒ 10x + 15y = -90
Rearrange the term of variables and solve for y
⇒ 15y = -10x - 90
Divided by 15 into both sides of the above equation,
⇒ y = (-10/15)x - 90/15 =
Reduce the fraction to the simplest form,
⇒ y = -(2/3)x - 6
Therefore, the required equation is -(2/3)x - 6 which equivalent to given equation 10x + 15y = −90.

In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10. What is the value of x?
Answers
Answer: The value of x= 18
Step-by-step explanation:
Given: In triangle EFG, angle E equals 8x-16, angle F equals x+8, and angle G equals 2x-10.
The sum of all angles of a triangle is 180°.
Therefore, in triangle EFG
∠E + ∠F +∠G= 180°
⇒ 8x-16 +x+8+ 2x-10 = 180
⇒ 11x-18= 180
⇒ 11x = 180+18
⇒11x=198
⇒ x= 18 [Divide both sides by 11]
Hence, the value of x= 18

4. Drew has 4 pieces of rope 1 meter long each. He cuts each rope into fifths.
a. how many fifths will he have after cutting all the ropes?
b. How long will each of the fifths be in centimeters?
(Please answer the question in the next 10 minutes, thank you!)
Answers
Answer:
a. 20 pieces
b. 20cm each
Step-by-step explanation:
a. 4*5=20
If he cut one of the ropes into 5 pieces, then you do the same to each of them. So that would be 5+5+5+5, which is 20.
b. 100/5=20cm
Using the question, we can assume that each rope is 1M, or 100cm. so instead of making 1meter split into 5 (which would be written as 1/5M) you instead do 100centimeters split into 5, which is 20cm each.

Alexia runs a dog walking business. She charges a $3.75 base fee for
each dog she walks, plus an additional $10.30 per hour that she walks the
dog. Each day she spends $4.50 on dog treats. Solve for how much money
Alexa would earn in one day if she worked for 5.5 hours.
Answers
Answer:
$55.90
Step-by-step explanation:
First, create an equation representing her earnings each day.
Let x represent the number of hours that she walks the dog.
Since she charges $10.30 per hour, the cost from walking is 10.3x
She also charges $3.75 as a base fee, which has to be added
Putting this together, we get the equation y = 10.3x + 3.75
Plug in 5.5 as x to find her earnings:
y = 10.3x + 3.75
y = 10.3(5.5) + 3.75
y = 60.4
Since the spends $4.50 on dog treats a day, we have to subtract this from her earnings:
60.4 - 4.5
= 55.9
So, if she works for 5.5 hours, she will earn $55.90
