What is the measure of A
The measure of ∠ A is 50°
What is a triangle?A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.
Given that a triangle ABC, and angle B and C are 100° and 30° respectively,
According to angles sum property of a triangle, we have,
∠ A + ∠ B + ∠ C = 180°
∠ A = 180° - (100° + 30°)
∠ A = 180° - 130°
∠ A = 50°
Hence, the value of angle A is 50°

Jeremiah paid $29.52 for a pair of boots that were on sale. The original price of the boots was $36.00. Enter the percentage discount for the cost of the boots.
Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
Final answer:
The percentage discount on the boots is calculated by first finding the discount amount ($6.48) and then dividing it by the original price ($36.00), which gives us an 18% discount.
Explanation:
To calculate the percentage discount on the boots, we must first determine the amount of the discount. The discount is the difference between the original price and the sale price, which is $36.00 - $29.52 = $6.48.
Next, we calculate the percentage discount using the formula:
Percentage Discount = (Discount ÷ Original Price) × 100%
Substituting in our numbers:
Percentage Discount = ($6.48 ÷ $36.00) × 100%
Percentage Discount = 0.18 × 100%
Percentage Discount = 18%
So, Jeremiah received an 18% discount on the boots.

what is the coordinate of the midpoint of line segment Q(-3,14) and R(7,5)
We can find the midpoint by using the two given coordinates and finding the average between them.
We will find the average between the x coordinates and the y coordinates.
We are given these two coordinates of line segment QR: (-3, 14) and (7, 5). Find the midpoint by finding the average (or mean) between the x coordinates (-3 and 7), and the y coordinates (14 and 5).
Find the average by adding up the two coordinates then dividing the answer you get by 2 (because you added two numbers).
x coordinates average: -3 + 7 = 4, 4/2 = 2; their average is 2
y coordinates average: 14 + 5 = 19, 19/2 = 9.5; their average is 9.5 (or 19/2)
Take the two averages and put them together so your answer is: the coordinate of the midpoint of line segment QR is (2, 19/2).

Griffin ordered a pair of sneakers online. He had a $16 credit that he applied toward the purchase, and then he used a credit card to pay for the rest of the cost. If the shoes cost $76, how much did Griffin charge to his credit card when he bought the sneakers?
Griffin used $60 on his credit card.
16 - 76 = 60
Final answer:
After applying a $16 credit to the purchase of $76 sneakers, Griffin charged $60 to his credit card.
Explanation:
Griffin has purchased sneakers online. The cost of the sneakers is $76, and he applied a $16 credit towards this purchase. To find out how much Griffin charged to his credit card, we need to subtract the credit from the total cost of the sneakers.
Calculation:
$76 (Total cost of sneakers) - $16 (Credit applied) = $60
Therefore, Griffin charged $60 to his credit card for the sneakers.
Explain how comparing 645 and 738 is different from comparing 645 and 649
When comparing these two sets of number, the first set is harder to find the different as you need to borrow from a column. For instance, when you start subtracting in the 10s place, you cannot take 40 away from 30.
Whereas in the second set, comparing the numbers is easy. They have the same 100s value and the same 10s value. You are simply comparing the 1s place.
Answer:
First, if we compare 645 and 738, the difference is significant, because those number have different units, different tenths and different hundreds.
However, if we compara 645 and 649, the difference isn't significant, because they have the same hundreds, the same tenths, but different units.
So, in terms of comparing numbers as such, we can tell that the difference in each comparison is about units, tenth and hundreds difference.
From this different comparison, the difference operation (subtraction) is also different, because it's not the same to subtract 645 from 738 than from 649, the difference is higher.

5(2x +8) = -8x + 4
Use distributive property:
10x +40 = -8x + 4
Subtract 40 from each side:
10x = -8x -36
Add 8x to each side:
18x = -36
Divide both sides by 18:
x = -36 / 18
x = -2

At the end of the month mr copley has $1473.61 in is checking account his checkbook showed the following transaction if made made an initial deposit of $75 that is not shown in his checkbook what was his balance at the beginning of the month
To find the balance at the beginning of the month, add the initial deposit and subtract the total transactions from the end of the month balance.
Explanation:To find the balance at the beginning of the month, we need to subtract the total transactions from the end of the month balance. First, we need to find the total transactions by adding up all the transactions in Mr. Copley's checkbook. Then, we subtract the total transactions from the end of the month balance, $1473.61, and add the initial deposit of $75 that is not shown in his checkbook. This will give us the balance at the beginning of the month.
Find the total transactions by adding up all the amounts in Mr. Copley's checkbook.Subtract the total transactions from the end of the month balance, $1473.61.Add the initial deposit of $75 that is not shown in his checkbook.The balance at the beginning of the month is the result of the previous steps.
The figure below is a square pyramid where the height of the pyramid is 2 centimeters and the volume is 24 cubic centimeters. If the volume of a pyramid is v=1/3bh, then what is the length of the base?
A.2cm
B.4cm
C.6cm
D.8cm
Final answer:
The length of the base of the square pyramid is calculated by rearranging the volume formula v = 1/3bh to solve for b, finding the base area, and then taking the square root to find the side length. With the given volume of 24 cm³ and height of 2 cm, the side length of the base is 6 cm. Therefore, the correct answer is C.
Explanation:
The student is asking how to find the length of the base of a square pyramid given its volume and height. The volume of a pyramid is given by the formula v = 1/3bh, where v is the volume, b is the area of the base, and h is the height. Since the pyramid is square, the area of the base (b) is equal to one side of the square base squared. With a volume (v) of 24 cm³ and a height (h) of 2 cm, we can substitute the values into the formula and solve for the base area b.
To find the side length of the base, we take the square root of the base area. Using the provided formula and values, we get:
v = 24 cm³
h = 2 cm
b = (3×v)/h = (3×24 cm³)/2 cm = 36 cm²
The side length of the base (l) is the square root of the base area: l = √b = √36 cm² = 6 cm. Therefore, the correct answer is C. 6 cm.
Catherine 168 pieces of gum playing at a bean bag toss in the county fair at school she gave three to every student in her math class she has 8 remaining how many students are in her class
Givens
Let the number of students in the class be x
Let the number of pieces of gum she gave out be 3x
Equation
3x + 8 = 168 This will not work out evenly. Let's try x - 1. The reason for that is because she may not give out anything to herself.
3(x - 1) + 8 = 168 This doesn't work either.
Well we have to choose. It's a rounding problem.
3x + 8 = 168 Subtract 8 from both sides.
3x = 168 - 8 Combine
3x = 160 Divide by 3 on both sides.
x = 160 / 3
x = 53.333333333
Since that can't be, we could say there were 53 students.
