3/8 = 15/a can someone please explain the steps for me? I have 2 hws due today and Idk how to do this
Answer:
I think the answer is 15/40
Step-by-step explanation:
So basically this looks like reducing. So first from the three-eights divide the fifteen by three that is 5. So then multiply 8 by 5 and a is = 40
proof divide 40 by 8

A ball thrown straight up in the air travels 90 inches in the first tenth of a second. In the next tenth of a second the ball travels 85 inches. After each additional tenth of a second, the ball travels 5 inches less than it did during the preceding tenth of a second. How long will it take before the ball starts coming back down? What is the total distance that the ball has traveled once it reaches its maximum height?
Answer:
855
Step-by-step explanation:
1.9 seconds is 19 tenths, so that means we add using the information given, which is that the ball travels 5 fewer inches every tenth of a second:
Time | Inches traveled
0.1 | 90
0.2 | 85
0.3 | 80
0.4 | 75
0.5 | 70
0.6 | 65
0.7 | 60
0.8 | 55
0.9 | 50
1.0 | 45
1.1 | 40
1.2 | 35
1.3 | 30
1.4 | 25
1.5 | 20
1.6 | 15
1.7 | 10
1.8 | 5
1.9 | 0
90+85+80+75+70+65+60+55+50+45+40+35+30+25+20+15+10+5+0=855
PQ = 3x + 14 and QR = 7x - 10; Find x.
Answer
3x+14=7x-10
14+10=7x-3x
24=4x
6=x
Answer:
6
Step-by-step explanation:
3x+14=7x-10
14+10=7x-3x
24=4x
6=x
please follow me...The value of x in the expression is 6.
To obtain the value of x, we equate both PQ and QR
PQ = 3x + 14
PQ = 3x + 14 QR = 7x - 10
PQ = QR
(3x + 14) = (7x - 10)
3x + 14 = 7x - 10
Collect like terms
3x - 7x = - 10 - 14
-4x = - 24
Divide both sides by - 4
x = - 24 / -4
x = 6
Hence, the value of x = 6

which explicit formula describes the sequence −9, −3, 3, 9, 15, …?
Group of answer choices
an = 9n + 6
an = 6n + 15
an = 6n - 15
an = 9n – 6
======================================================
Explanation:
This sequence is arithmetic
The first term is a = -9
The common difference is d = 6 since we're adding 6 to each term to get the next one (eg: -3+6 = 3 or 3+6 = 9 or 9+6 = 15)
Plug those values into the arithmetic nth term formula below
an = a + d*(n-1)
an = -9 + 6*(n-1)
an = -9 + 6n-6
an = 6n - 15
--------------
As a check, let's plug in something like n = 1
an = 6n - 15
a1 = 6*1 - 15
a1 = 6 - 15
a1 = -9
We see that the 1st term is -9, which matches the sequence given
Now let's plug in n = 2
an = 6n - 15
a2 = 6*2 - 15
a2 = 12 - 15
a2 = -3
The 2nd term is -3. This also matches.
I'll let you check the other values of n to confirm the answer.

You make two batches of cookies. In batch A you use 3/4 of a cup of flour to every 1/5 of a cup of chocolate chips. In batch B you use 2/3 of a cup of flour for every 1/6 of a cup of chocolate chips. Find the unit rates for flour per cup of chocolate chips for each batch and decide which cookies have more chocolate chips.
Answer:
a) The unit rate are:
Batch A = 3 3/4 flour per cup of chocolate chips
Batch B = 4 flour per cup of chocolate chips.
b)Batch A is the cookie with the most chocolate chips.
Step-by-step explanation:
In batch A you use 3/4 of a cup of flour to every 1/5 of a cup of chocolate chips.
The unit rate for flour per cup of chocolate chips for batch A =3/4 cups of flour ÷ 1/5 cup of chocolate chips
= 3/4 ÷ 1/5
= 3/4 × 5/1
= 15/4
= 3 3/4 flour per cup of chocolate chips.
In batch B you use 2/3 of a cup of flour for every 1/6 of a cup of chocolate chips.
The unit rate for flour per cup of chocolate chips for batch B =
2/3 of a cup of flour ÷ 1/6 of a cup of chocolate chips.
= 2/3 ÷ 1/6
= 2/3 × 6/1
= 4 flour per cup of chocolate chips.
b)
Number of chocolate chips used in Batch A = 1/5 cup =>0.2 cup
Number of chocolate chips used in Batch B = 1/6 cup => 0.167 cup
0.2 cup is larger than 0. 167 cups.
Therefore, Batch A is the cookies with the most chocolate chip
Mr. Turner lives in St. Louis, Missouri. Mr. Turner employer pays 100% of his medical insurance. He has rent of $800 and $600 for car payment, $100 light bill, and $300 car insurance. His payroll and income taxes are estimated to be $287.
Given Data:
medical insurance paid = 100%.
rent = $800.
Car payment = $600.
Light bill = $100.
Car insurance = $300.
Taxes = $287.
Solution:
Minimum salary to bear all expenses is
S = Basic expenses + Payroll and taxes
S = $( 800 + 600 + 100 + 300 + 287)
S = $2087.00
His monthly salary is $2087.00 .
This is the required amount needed.

The mistake was in line 2:
4/1 in line 1 was changed to 1/4 in line 2 by a mistakeWrite an equation in point slope form of the line graphed below. (Use the right hand point)
Answer:
y-3 = (-1/4)(x-4)
Step-by-step explanation:
Point-slope form is written as y-y1 = m(x-x1)
The y - 3 portion comes from the coordinate plotted, where the y-coordinate is 3, so from the function y-y1, y1 = 3.
The m equals the slope, the rise over run. Choose the two coordinates, subtract the y's from each other and the x's from each other, get the absolute value of them, and then put in the fraction (y/x) to get your slope of m. The 2 coordinates you have are (0,4) and (4,3). You subtract |4-0| and |3-4|, so you get for the x's = 4, and the y's=1. Now the slope was y/x, so 1/4 is your slope for m.
For the x, use the same coordinate you got for your y to get your x, so the x was 4.
Plug them all into the point-slope function to get your answer, which is y - (3), (-1/4) (x - [4])
Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right angle. The length of S T is 9 and the length of T Q is 16. The length of R T is x. What is the value of x? 12 units 15 units 20 units 25 units
Answer:
RT = 12 units
Step-by-step explanation:
From the figure attached,
ΔSRQ is right triangle.
m∠R = 90°
An altitude has been constructed from point T to side SQ.
m∠RTQ = 90°
By applying geometric mean theorem in triangle SRQ,
[tex]\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}[/tex]
[tex]\frac{x}{9}=\frac{16}{x}[/tex]
x² = 16 × 9
x² = 144
x = √144
x = 12
Therefore, length of altitude RT is 12 units.
Answer:
12 units

Ashley has two buckets filled with water. The large bucket contains 36 gallons and is leaking at a rate of 0.12 gallons per hour. The small bucket contains 12 gallons and is leaking at a rate of 0.6 gallons per hour.
Which inequality can be used to find the number of hours, h, at which the larger bucket will have less water than the smaller bucket?
Answer:
36 - 0.12h < 12 - 0.6h
Step-by-step explanation:
Large bucket:
36 gallons and is leaking at a rate of 0.12 gallons per hour.
= 36 - 0.12h
Smaller bucket:
12 gallons and is leaking at a rate of 0.6 gallons per hour
= 12 - 0.6h
The inequality that can be used to find the number of hours, h, at which the larger bucket will have less water than the smaller bucket is
36 - 0.12h < 12 - 0.6h

Which simplified ratio correctly compares 12 yard to 20 feet?
A. 5:9
B. 3:5
C. 9:5
D. 5:3
Answer:
The answer is B
Step-by-step explanation:
If you look at the problem you can put 12 and 20 into a ratio like this
12:20
then if you simplify it by like terms say 4
12 divided by 4 is 3
20 divided by 4 is 5
3:5
= B

35 ÷ 4 = 8 R3
Answer:

So, say you're dividing 35 jellybeans with 3 of your friends (you're the fourth person, because you need some jellybeans too!)
Each would get 8 jellybeans. But there are 3 left over.
Split each jellybean into 4 parts.
Each of you would get 3/4 of one of the jellybeans. (three tiny parts of the total four tiny pieces)

The length of a rectangle is twice as great as its width. When both the width and length are increased by 5 inches, the new rectangle has perimeter of 80 inches. Show an equation to find the length and width of the original rectangle. Solve the equation and give the original length and width.
Answer:
Original rectangle
Length = 20 inches
Width = 10 inches
Step-by-step explanation:
Let
Original rectangle
Width = x
Length = 2x
When both the width and length are increased by 5 inches, the new rectangle has perimeter of 80 inches
New rectangle
Width = x + 5
Length = 2x + 5
Perimeter = 80 inches
Perimeter of a rectangle = 2(length + Width)
80 = 2{(x+5) + (2x+5)}
80 = 2( x + 5 + 2x + 5)
80 = 2(3x + 10)
80 = 6x + 20
80 - 20 = 6x
60 = 6x
x = 60 / 6
= 10
x = 10 inches
The length and width of the original rectangle
Width = x
= 10 inches
Length = 2x
= 2(10)
= 20 inches
