An object has a volume of 7cm³ and a mass of 56g. What is its density in g/cm³?
Hint: density × volume = mass
Answer:8
Step-by-step explanation;Since you want to find the density but you already have the mass you do the inverse operation and divdie 56 by 7 and get 8.
Answer:
8 g/cm³
Step-by-step explanation:
Density can be defined as the amount of substance per unit volume. To calculate density, divide the mass by volume.
Given: volume= 7cm³, mass= 56g
Density
= 56 ÷7
= 8 g/cm³

A company found that monthly reimbursements to their employees could be adequately modeled by a uniform distribution over the interval $10,000 < x < 15,000.
What is the probability of employee reimbursements exceeding $12,000 next month?
Answer:
0.6 = 60% probability of employee reimbursements exceeding $12,000 next month
Step-by-step explanation:
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
A company found that monthly reimbursements to their employees could be adequately modeled by a uniform distribution over the interval $10,000 < x < 15,000.
This means that, in thousands of dollars, [tex]a = 10, b = 15[/tex]
What is the probability of employee reimbursements exceeding $12,000 next month?
[tex]P(X > 12) = \frac{15 - 12}{15 - 10} = \frac{3}{5} = 0.6[/tex]
0.6 = 60% probability of employee reimbursements exceeding $12,000 next month
Find the sum of the first 378 counting numbers
WITH SOLUTION
Step-by-step explanation:
Counting numbers are 1,2,3,4,5........,378
Here it forms an AP with a = 1, d=1, an or l=378, n=378
Sum of 378 numbers = n/2(a+l)
= 378/2(1+378)
= 189(379)

the perimeter of a rectangle is 24 inches. The length is 2 inches. what is the width?
Answer:
width = 10
Step-by-step explanation:
Step-by-step explanation:
P=24
L=2
Perimeter of rectangle is 2(L+W)
24=2(2+W)
24=4+2W
Subtract 4 from both sides you get 20=2W
Now divide by 2 on both sides you get W=10 inches

Answer:
x = 30
Step-by-step explanation:
Let the measure of ∠MKQ be x°.
It's given that:-
Measure of ∠JKL is twice the measure of ∠MKQ.⇒ ∠JKL = 2∠MKQ
⇒ ∠JKL = 2x° _____ (eqn.1)
∠JKL & ∠MKQ are complementary angles.⇒ ∠JKL + ∠MKQ = 90°
⇒ 2x° + x° = 90°
⇒ 3x° = 90°
⇒ x° = [tex]\frac{90}{3} = 30[/tex]
∴ Hence ,
∠MKQ = 30°∠JKL = 2∠MKQ = 2×30 = 60°Which ones are correct?

Find the equation of a line that passes through the point (-2,4) and has a gradient of -3.
Leave your answer in the form
y
=
m
x
+
c
Equation of a line is y = mx +c
m is the gradient, which is given as -3 so now you have:
y = -3x + c
Replace y and x with the given point and solve for c:
4 = -3(-2) + c
Simplify:
4 = 6 + c
Subtract 6 from both sides:
c = -2
The equation becomes:
y = -3x-2

Over the last 3 evenings, Huda received a total of 94 phone calls at the call center. The third evening, she received 3 times as many calls as the second evening.
The second evening, she received 9 fewer calls than the first evening. How many phone calls did she receive each evening?
Please answer??
Answer: See explanation
Step-by-step explanation:
Let the number of calls received the first evening be x.
The second evening, she received 9 fewer calls than the first evening. This will be: = x - 9
The third evening, she received 3 times as many calls as the second evening. This will be: = 3(x - 9) = 3x - 27
Then, the expression for each evening can then b put together and solved further as:
x + (x - 9) + (3x - 27) = 94
x + x - 9 + 3x - 27 = 94
5x = 94 + 9 + 27.
5x = 130
x = 130/5
x = 26
First evening = 26 calls
Second evening = x - 9 = 26 - 9 = 17 calls
Third evening = 3x - 27 = 3(26) - 27 = 78 - 27 = 51 calls

Proofs in the picture
The value of y is 225 when x is 50 from the given graph.
What is Coordinate System?Arrangement of reference lines or curves used to identify the location of points in space is called as Coordinate system.
We need to find the value of y when x is fifty.
In the given graph we have to draw a perpendicular line at x =50.
Now we have to check the point where the perpendicular line touches the graph curve.
Take the corresponding value of y.
When x is 50 the value of y is nearly to 225.
Hence, the value of y is 225 when x is 50.

Sum of 2 numbers is 36. The larger is 3 more than twice the
smaller number, Find the smaller number below.
Answer:
11
Step-by-step explanation:
so we just make a system of equations:
x+y=36
say that x is the larger and y is the smaller
x-3=2y
so we can combine the equations and solve for x and y
re-arrange x-3=2y to be x=2y+3
x+y=36
x=2y+3
insert the value for x into x into x+y=36
2y+3+y=36
3y+3=36
y=11
now insert that back into x+y=36
11+x=36
x=25
Out of the two numbers x and y, 11 is the smaller number

A basketball player has made 12 of his last 20 free throws, which is a free throw percentage of 60%.
How many more consecutive free throws would he need to make to raise his free throw percentage to 75%?
Answer:
Need ( 3 ) more consecutive free throws to make to raise his free throw percentage to 75%
