r= 130/2.5
130=r2.5
it would be 52 because you have to divide.... so you would divide 130 by 2.5 and then you would get 52. hope this helps.
A new health drink has 150% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the drink? There are nothing mg of the vitamin in the drink.
Answer:
the number of milligrams of the vitamin in the drink is 75 mg
Step-by-step explanation:
The computation of the number of milligrams of the vitamin in the drink is as follows:
= RDA of the vitamin × given percentage ÷ percentage
= 50 mg × 150 ÷ 100
= 75 mg
hence, the number of milligrams of the vitamin in the drink is 75 mg
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Fred weighs 40 pounds less than twice Barney. Their combined weight is 320 pounds. Let F = Fred's weight in pounds and B = Barney's weight in pounds. Write a system to represent the situation. DO NOT SOLVE.
Answer:
Step-by-step explanation:
Using the information provided we can create two different equations for this system. The first of which would be Fred's overall weight, while the second equation would be Fred's and Barney's combined weight. These equations would be the following...
F = 2B - 40
320 = F + B
As requested I will not solve the system of equations and leave them as they are.
There are 165 laptops and desktop computers in a lab. There are 9 more laptops than desktop computers. What is the total number of laptops in the lab?
Answer:
87
Step-by-step explanation:
Let d = number of desktops.
Let a = number of laptops.
a + d = 165
a = d + 9
d = a - 9
a + d = 165
a + a - 9 = 165
2a - 9 = 165
2a = 174
a = 87
Answer: 87
Answer:
87

3(1−9a)+22a=2(2a−9)−15
i need a step by step explanation
Step-by-step explanation:
3(1-9a)+22a=2(2a-9)-15
3-27a+22a=4a-18-15
-27a+22a-4a=-18-15-3
-a=-36
a=36
Answer:
A= 4
Step-by-step explanation:
3(1-9a)+22a=2(2a-9)-15
3-27a+22a=2(2a-9)-15
3-5a=2(2a-9)-15
3-5a=4a-33
3-5a-3=4a-33-3
-5a=4a-36
-5a-4a=4a-36-4a
-9a=-36
-9a/-9 = -36/-9

You have made a poster that is 4 feet by 5 feet to hang on a wall, you want to use the reaming 10 sqaure feet of fabric to add a decorative border width. What should the width of the border be
Answer:
0.556 foot wide or 6 ²/₃ inches wide
Step-by-step explanation:
first we must calculate the total perimeter of the poster that will be decorated with the fabric:
the total perimeter of the poster = 4 + 4 + 5 + 5 = 18 feet long
you have 10 square feet of fabric, so its width should be 10 / 18 = 0.556 foot wide or 6 ²/₃ inches wide

Grace rakes leaves everyday for one week. She fills the same number of bags with leaves on each of the 5 weekdays. She fills 11 bags over the weekend. At the end of the week, Grace has filled a total of 26 bags. She wants to know how many bags she filled each weekday.
Answer:
3 bags per weekday
Step-by-step explanation:
Total bags of leaves at the end of the week = 26 bags
Bags of leaves she fills over the weekend = 11 bags
Bags of leaves she fills during weekdays = x bags
Total bags of leaves at the end of the week = Bags of leaves she fills over the weekend + Bags of leaves she fills during weekdays
26 = 11 + x
Subtract 11 from both sides
26 - 11 = 11 - 11 + x
15 = x
x = 15 bags
If she fills the same number of bags with leaves on each of the 5 weekdays.
how many bags she filled each weekday.
Bags she filled each weekday = Total Bags of leaves she fills during weekdays / 5 weekdays
= 15 bags / 5 weekdays
= 3 bags per weekday
Answer:
3
Step-by-step explanation:
1. Bags filled on weekdays + bags filled on weekends = total bags filled
2. 5b + 11 = 26
3. Isolate variable (subtract 11 from both sides) = 5b=15
4. Divide both sides by 5 = 15/5 = 3
5. How many bags does Grace fill each weekday? = 3

What is 3x-2y=24 in slope intercept form??
this doesn't make sense how do you find the y and x and slope
Answer: 3x-2y=24 in slope intercept form is [tex]y=\frac{2}{3}x -12[/tex]
The graph of the equation is in the attachment
Step-by-step explanation: Slope intercept form is y = mx + b
m is the slope b is the y-intercept x is the "input" in the equation y is the "output" or the y-value in the graph for a given x-value.
You need to rearrange the standard form to slope-intercept to isolate y on the left side of the equation.
3x - 2y = 24 Standard form. Subtract 3x from both sides.
-2y = -3x + 24 divide both sides by -2
-2y/-2 = -3x/-2 + 24/-2 . Simplify.
y = 3x/2 - 12 .
To clarify the slope as a fraction
[tex]y=\frac{2}{3}x -12[/tex]
Consider p(x)=3x^3+ax+5a, a is an element of the integers.
The polynomial p(x) leaves a remainder of -7 when divided by (x-a). Show that only one value of a satisfies the above condition and state it’s value.
By the remainder theorem,
p(a) = 3a³ + a² + 5a = -7
so that
3a³ + a² + 5a + 7 = 0
Since you know a is an integer, you can try to factorize this, or use the rational root theorem to generate a list of potential rational roots, and from there you'd select the integer roots. The rational ones are of the form m/n, where m divides the constant term 7 and n divides the leading coefficient 3. They are
a = ± 1 or ± 1/3 or ± 7 or ±7/3
so there are 4 integer candidates,
a = -1 or 1 or -7 or 7
Check the value of f(a) = 3a³ + a² + 5a + 7 at each of these:
a = -1 → f(a) = 0
a = 1 → f(a) = 16
a = -7 → f(a) = -1008
a = 7 → f(a) = 1120
and only a = -1 is a root of 3a³ + a² + 5a + 7, so that's your answer. In fact,
3a³ + a² + 5a + 7 = (a + 1) (3a² - 2a + 7)

Answer:
NQ=15
Step-by-step explanation:
To solve this we can use the side-splitter theorem.
NS/SR=NP/PQ
PQ=x since we do not know it's value
now to subsitute the given/known values.
12/78=2/x
solve for x using cross multiplication.
12x=156
x=13
PQ=13
NQ= PQ+NP
NP=2
NQ=13+2
NQ=15
The length of NQ is 15.

A square has a perimeter of 100m. what is the length of each side?
Answer:
25m
Step-by-step explanation:
The perimeter of a square= 4L (L=length of the side)
so L=perimeter /4
=100/4=25m

she should buy 3 quarts and keep the remainder which can possibly cover 30 square feet.
Matthew dropped a tennis ball off the roof of 100 foot tall building. The objects height (y) is modeled by the equation below. At what time (t) does the ball hit the ground? Round your answer to the nearest tenth
Answer:
2 seconds later
Step-by-step explanation:
Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64
The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;
Since y = -16t² + 64
0 = -16t² + 64
16t² = 64
t² = 64/16
t² = 4
t = ±√4
t = 2 and -2
Time cannot be negative, hence the ball hits the ground 2 seconds later.
Note that the equation used was assumed. Similar solution can be applied for any given equation.

© As an estimation we are told 5 miles is 8 km.
Convert 25.9 miles to km.
Answer:
41.68201 km=25.9 miles
Step-by-step explanation:
Answer:
Step-by-step explanation:
5m=8k
25.9m = ?k
25.9/5 = 5.18
5.18 X 9 = 46.62
Therefore 25.9 miles is 46.62 km
Distance for 3 minutes and at the speed of 17m/s
Answer: speed = 17m/s
time taken = 3min = 3 x 60 = 180 seconds (1min = 60sec)
distance = ST
= speed x time
= 17 x 180
= 3060m
