Answer: d) 60
Step-by-step explanation:
so two numbers a+b=90 and also a-b=30
Lets assume a is the larger number. So we can plug and chug for time purposes I will explain why 60 is the answer. so 60-30=30 so b would be 30 and a would be 60. Also a+b or 60+30= 90 and that is the case the smaller number is 30 and the larger number is 60

Find the area of a right triangle with a height of 8 1/2 feet and a base of 15 feet
Answers
Answer:
63.75
Step-by-step explanation:
The equation for finding the area of a triangle is 1/2b x h
b = base
h = height
b = 15
h = 8.5
15(1/2) x 8.5
7.5 x 8.5 = 63.75
Answer:
A = 63.75 ft^2, or 63 3/4 ft^2
Step-by-step explanation:
The formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
With h = 8.5 ft and b = 15 ft, the area of the triangle in question is
A = (1/2)(8.5)(15)ft^2, or
A = 63.75 ft^2, or 63 3/4 ft^2
At the youth center, the committee has decided to create a circular shaped flower bed. They plan to cover the flower bed with mulch. A flower bed with a 12' diameter will cost $150 to cover with mulch. A flower bed with an 18' diameter will cost $300 to cover. Which is the better value?
Answers
Answer:
12 in diameter bed will give better value
Step-by-step explanation:
Given:
Cost of cover 12 in diameter bed = $150
Cost of cover 18 in diameter bed = $300
Find:
Better value
Computation:
Area of bed = πr²
Area of 12 diameter of bed = (22/7)(6)²
Area of 12 diameter of bed = 113.14 in²
Area of 18 diameter of bed = (22/7)(9)²
Area of 18 diameter of bed = 113.14 in²
Area of 18 diameter of bed = 254.57 in²
Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar
Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar
So,
12 in diameter bed will give better value

Maritza worked at an ice cream parlor selling milkshakes and ice cream cones. Altogether, she sold 149 milkshakes and ice cream cones. The milkshakes sold for $4 and the ice cream cones for $3. The total amount collected was $533. How many milkshakes and ice cream were sold?
Answers
Answer:
86 milkshakes and 63 ice cream were sold
Step-by-step explanation:
Let the amount of milkshake sold be x
Let the amount of ice cream sold be y
If she sold 149 milkshakes and ice cream cones then;
x+y = 149 ... 1
If the milkshakes sold for $4 and the ice cream cones for $3, with total amount #533 collected then;
4x + 3y = 533 ....2
Solve both equations simultaneously
x+y = 149 ... 1 * 4
4x + 3y = 533 ....2 * 1
________________________
4x+4y = 596
4x+3y = 533
Subtract
4y-3y = 596-533
y = 63
since x +y = 149
x+63 = 149
x = 149 - 63
x = 86
Hence 86 milkshakes and 63 ice cream were sold

Beach towels are on sale for $1.50 off of the regular price. Ms. Ortiz buys 4 beach towels on sale for a total of $33.96. Use equations to determine the regular price of a beach towel.
Answers
Answer: $9.99
Step-by-step explanation:
From the question, we are informed that beach towels are on sale for $1.50 off of the regular price and that Ms. Ortiz buys 4 beach towels on sale for a total of $33.96.
The amount for each beach towel bought will be:
= $33.96/4
= $8.49
Since there's $1.50 off the normal price, that means the normal price for each will have been:
= $8.49 + $1.50
= $9.99

Step-by-step explanation:
The question is essentially asking the ratio of the volumes.
Va = πr²h = π(15²)(20)
Vb = πr²h = π(19²)(19)
The ratio of volumes is ...
Va/Vb = π(15²)(20)/(π(19³)) = (15²)(20)/19³ ≈ 0.65607
Container B will be about 65.6% full when container A is empty.

department store sells a pair of shoes with a 33% discount coupon. If the store orignially sold the shoes for $55.25, what is the sale price?
Answers
Answer:
The sale price is $37.02.
Step-by-step explanation:
With the information provided, you can find the sale price by calculating 33% of the price which is the discount and subtracting that amount from the price:
$55.25*33%=$18.23
$55.25-$18.23=$37.02
According to this, the answer is that the sale price is $37.02.

What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The arithmetic sequence is given below.
3/8, 3/4, 1 ¹/₈, 3/2, 1 ⁷/₈, ......
Convert the mixed fraction number into a fraction number. Then we have
3/8, 3/4, 1 ¹/₈, 3/2, 1 ⁷/₈, ......
3/8, 3/4, 9/8, 3/2, 15/8, ........
The first term of the arithmetic sequence is 3/8. And the common difference of the arithmetic sequence will be given as,
d = 3/4 - 3/8
d = 6/8 - 3/8
d = (6 - 3)/8
d = 3 / 8
The sequence is recursive and can be represented by the function will be f(n + 1) = f(n) + 3/8.
