The ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 . The store has 90 BMX bikes . How many mountain bikes does the store have ?
Answer: 60
Step-by-step explanation:
From the question, we are informed that the ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 and that the store has 90 BMX bikes .
To calculate the number of mountain bikes that the store has goes thus:
= 2/3 × 90
= 2 × 30
= 60 mountain bikes

Write the equation of the line passing through (2,3) and perpendicular to y = 2/3 x + 7.
Answer:
y = 2/3x
Step-by-step explanation:
So we know, when lines are perpendicular that they share the same slope. The slope in the equation of y = 2/3x + 7 is 2/3x. So, we have our slope. Now, we just need to find our b. We plug in the point that you gave us into the equation y = mx + b.
3 = 2/3(2) + b
we multiply the denominator 3 by 2, then divide that by the numerator 2.
3 = 3 + b
subtract 3 from itself and from the opposite side of the equal side 3.
0 = b
in the end, there is no b for this equation. Our answer is
y = 2/3x
Will give brainliest if correct.
Answer:
y = -5x - 10
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Now, in your case:
5x + y = -10
Move 5x (don't forget to change the signs!):
y = -5x - 10

World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages. A restaurant uses 36 pounds of this coffee each month. How many cases must be ordered per month?
Answer:
The number of cases to be purchased is 2.
Step-by-step explanation:
Giving the following information:
World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages.
First, we need to calculate how many pounds are in each case.
1 pound = 16 ounces
1 case= (48*6)/16
1 case= 18 pounds
Now, the number of cases required each month:
36 pounds = 18*x
x= number of cases
x= 36/18
x= 2
The number of cases to be purchased is 2.

Rachael earned $42 for 3 1/2 hours at her job today. How much does Rachel earn per hour ?
Answer:
$12
Step-by-step explanation:
It is given that,
Rachael earned $42 for [tex]3\dfrac{1}{2}[/tex] hours at her job today. It means,
For 7/2 hours, earning is $42
For 1 hour, we divide $42 by 7/2 as follows :
[tex]1\ h=\dfrac{42}{\dfrac{7}{2}}\\\\=\dfrac{42\times 2}{7}\\\\=\$12[/tex]
So, he will earn $12 per hour.
4. Rudy is training for a race. On Monday he ran
2 km. On Tuesday he ran 15% farther than on
Monday. If he increases his running distance
by the same percentage each day, on which day
will he first run more than 4 km?
A. Wednesday
B. Thursday
C. Friday
D. Saturday
Answer:
C
Step-by-step explanation:
You add .3 km to the first day (tuesday)
then .6 then next day (wedneday)
next you add .9 on the next day (thursday)
finally you add 1.2 km on Friday
2.3+0.6+0.9+1.2=4 km
Michael got a $50 gift card to an online music store. She uses the gift card to buy an album for $9.99. She also wants to use the gift card to buy some songs. Each song costs $1.29. Which of these inequalities describes this situation, where n is the number of songs Michael wants to buy?
Answer:
$9.99 + $1.29n ≤ $50
Step-by-step explanation:
Given that:
Worth of gift card = $50
Cost of album purchased = $9.99
Cost per song to purchase = $1.29
Number of songs to purchase = n
Inequality to model the situation :
Cost of album + cost per song * (Number of songs) ≤ worth of gift card
$9.99 + ($1.29 * n) ≤ $50
$9.99 + $1.29n ≤ $50

Scientists have found that the relationship between the area of an island and the number of species can be modeled approximately by S=-3.404+103.2ln(A) S=−3.404+103.2ln(A), where AA is the area in km^2km 2 and SS is the number of species.
Answer:
[tex]A=e^{(S+3.404/103.2)[/tex]
Step-by-step explanation:
Step one:
we are told that the relationship between the number of species and the island area is given as
[tex]S=-3.404+103.2ln(A)[/tex]-----------------1
based on any given value for either area or number of species, we can find the other.
say we want to find the land area for a given amount of specie
Step two:
we first make area A subject of the formula.
[tex]S=-3.404+103.2ln(A)[/tex]
let us isolate [tex]ln(A)[/tex]
[tex]S + 3.404 = 103.2ln(A)[/tex]
Divide both sides by 103.2 we have
[tex](S + 3.404)/103.2 = ln(A)[/tex]
Now, exponentiate both sides using the base e.
[tex]A=e^{(S+3.404/103.2)[/tex]----------------2
for a given value of "S" we can find the area A based on the above expression.

calculate the combined surface area of the following three dimensional objects
Answer:
455.53cm^2
Step-by-step explanation:
diameter of hemisphere = 10cm
radius of hemisphere = 10/2 cm = 5cm
height of hemisphere = radius of hemisphere = 5cm
height of cylinder = 12cm - 5cm = 7cm
surface area = 2pi(5)7 + pi(5)^2 + 2pi(5)^2 = 455.53cm^2 (5sf)

Segment AB is the diameter of circle M. The coordinates of A are (1,6). The coordinates of M are (-3, 8). What are the coordinates of B
1) (-7,10)
2) (5,4)
3) (-1,7)
4) (-2,1)
Step-by-step explanation:
Let the midpoint formula be expressed as;
M(X,Y) = {x2+x1/2, y2+y1/2}
X = x2+x1/2
Y = y2+y1/2
Get x2
-3 = x2 + 1/2
-6 = x2 + 1
x2 = -6-1
x2 = -7
Get y2;
Y = y2+y1/2
8 = y2+6/2
16 = y2+6
Y2 = 16-6
y2 = 10
hence the coordinate of B is (-7, 10). Option A is correct
-7 + 3x = -10x +25
Show the work
Answer:
Step-by-step explanation:
Move -7 to the left, so make 7 positive and & move it next to 25
1. 3x = -10x +25+7
combine 25 & 7
2. 3x=-10x+32
move 10 to the side & combine with 3x
3. 3x+10x=+32
4. 13x = 32
lastly divide 32 from 13
x= 32/13 OR x= 2 6/13Answer:x=32/13
Step-by-step explanation:
Rearrange terms−7+3=−10+25−7+3x=−10x+25
3−7=−10+25
add 7 to both sides of the equation
then Simplify
add 10 to both sides of the equation the
x=32/13

A dressmaker needs to cut 6-inch pieces of ribbon from rolls of ribbon that are 9 feet in length. How many 6-inch pieces can the dressmaker cut from 15 of these rolls of ribbon? Before you try that problem, answer the question below. How many inches of ribbon does the dressmaker have, in total?
Answer:
Step-by-step explanation:
Answer:
60 pieces
Step-by-step explanation:
What we know:
There are 12 inches in a foot
There are 5 6-feet lengths of ribbon
So, we simply need to multiply.
Since there are 12 inches in a foot, and we only need 6 inches for each one, we can see that she makes 2 pieces for each foot.
Multiply
2*6=12
She makes 12 pieces for each length of ribbon.
Now multiply it by 5
12*5= 60
She can make 60 pieces from 5 of these length of ribbon.
Hope this helps!
Type the correct answer in the box. Use numerals instead of words. What value of x makes this equation true? -2x + 3 = -15
What does x =
Answer:x=9
Step-by-step explanation:
-2x+3=-15
Subtract 3 on both sides:
-2x+3-3=-15-3
-2x=-18
Divide -2 on both sides:
-2x/-2=-18/-2
x=9
If the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.
What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the equation as follows -
- 2x + 3 = - 15
The given equation is -
- 2x + 3 = - 15
Solving, we get -
- 2x = - 15 - 3
- 2x = - 18
2x = 18
x = 9
Therefore, if the expression (- 2x + 3) is equivalent to (- 15), then [x] is equivalent to 9.
