Answer:
15
Step-by-step explanation:
The GCF of 25 and 35, is 15
Answer:
5
Step-by-step explanation:
Use the L method or the tree method. If you go through your numbers and see which number can divide both 25 And 35, you should find 5 because both of them end in 5 Since anything is divisible by 5 if it has a 0 or a 5 as the ones.
If you also needed help with the LCM, it is, keep one of the fives and divide the other to get rid of the five, then multiply them all together, so 25 * 7 = 175.

the sum of 2 numbers is 65 and the difference is 7
Answer:
Hello There!!
Step-by-step explanation:
The answer is=>The sum is x + y = 65
The difference is x - y = 7 .....x = 7 + y
7 + y + y = 65
7 + 2y = 65
2y = 58
y = 29
x + y = 65
x + 29 = 65
X = 36
The Sum: 36 + 29 = 65
The Difference: 36 - 29 = 7
hope this helps,have a great day!!

Answer:
36 and 29
Step-by-step explanation:
The sum of the two numbers is 65 and their difference is 7. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:
x + y = 65
The difference between x and y is 7. In other words, x minus y equals 7 and can be written as equation B:
x - y = 7
Now solve equation B for x to get the revised equation B:
x - y = 7
x = 7 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 65
7 + y + y = 65
7 + 2y = 65
2y = 58
y = 29
Now we know y is 29. This means that we can substitute y for 29 in equation A and solve for x:
x + y = 65
x + 29 = 65
X = 36
Summary: The sum of two numbers is 65 and their difference is 7. What are the two numbers? Answer: 36 and 29 as proven here:
Sum: 36 + 29 = 65
Difference: 36 - 29 = 7

A cube has a volume of 729 cubic centimeters. What can be concluded about the cube? Check all that apply.
Recall the formula Cube volume = s cubed.
The side length, s, can be found using the equation 3 s = 729
This is a perfect cube.
The side length is 243 centimeters.
The side length is 9 centimeters.
Taking the cube root of the volume will determine the side length.
If you multiply the volume by three, you can determine the side length.
Answer:
b c d h
Step-by-step explanation:
i took the test
The true conclusion about the cube are :
This is a perfect cube
The side length is 9 centimeters
Taking the cube root of the volume will determine the side length.
What is volume?A volume is simply defined as the amount of space occupied by any three-dimensional solid. These solids can be a cube, a cuboid, a cone, a cylinder or a sphere. Different shapes have different volumes.
Volume of a cube = l³
where
l = length
Therefore,
volume = l³
729 = l³
cube root both sides
l = ∛729
l = 9 cm
Therefore, what is true about the cube is as follows:
This is a perfect cube
The side length is 9 centimeters
Taking the cube root of the volume will determine the side length.

If 18 people share a barrel of apples equally,each gets 12 apples.if there had been 6 fewer people,how many apples would each person get ?
Answer:
18 apples
Step-by-step explanation:
If 18 people each get 12 apples, then the total number of apples is 18*12=216.
If there were 6 fewer people, there would 18-6=12 people.
To split the total 216 apples between 12 people, so 216/12=18.
Each person would get 18 apples.

Answer:
K = 84°
L ; M = 48 ; 48
Step-by-step explanation:
L = (5x + 18)
M = (3x + 30)
K = k
L + M + K = 180° (sum of angles in a triangle)
The two base angles are equal :
Hence ;
5x + 18 = 3x + 30
5x - 3x = 30 - 18
2x = 12
x = 6
Hence,
L = 5x + 18 = 5(6) + 18 = 30 + 18 = 48°
M = 3x + 30 = 3(6) + 30 = 48°
K = 180 - (48 + 48)
K = 180 - 96
K = 84°

A salesperson works 40 hours per week at a job where
she has two options for being paid. Option A is an hourly wage of $
24. Option B is a commission rate of
8% on weekly sales. How much does
she need to sell this week to earn the same amount with the two options?
Answer:
12,000 in sales
Step-by-step explanation:
$24/hour x 40 hours=960 salary
sales x commission rate =salary
sales x .08=960
sales =960/.08
sales=12,000

below.
No links please I really need an answer
Answer:
284 [tex]ft^{2}[/tex]
Step-by-step explanation:
Area of triangle = bh/2 = 4(8)/2 = 16
Area of both triangles = 32
Area of left face = bh = 8(12) = 96
Area of right face = bh = 9(12) = 108
Area of bottom = bh = 4(12) = 48
Total lateral area = 32 + 96 + 108 + 48 = 284

A regression of y = calcium content (g/L) on x = dissolved material (mg/cm2) was reported in the article "Use of Fly Ash or Silica Fume to Increase the Resistance of Concrete to Feed Acids" (Mag. Concrete Res., 1997: 337–344). The equation of the estimated regression line was y = 3.678 + .144x, with r2 = .860, based on n = 23.
a. Interpret the estimated slope .144 and the coefficient of determination .860.
b. Calculate a point estimate of the true average calcium content when the amount of dissolved material is 50 mg/cm2.
c. The value of total sum of squares was SST = 320.398. Calculate an estimate of the error standard deviation σ in the simple linear regression model.
Answer:
a) The slope = 0.144 , means that an increase in dissolved material by 1 mg/cm^2 will lead to an increase in Calcium content by 0.144 g/l
while the coefficient of determination = 0.869 , means that 86% of the variation ( natural ) of calcium content is explainable using the Linear model.
b) 10.878
c) S ≈ 1.99
Step-by-step explanation:
a) The slope = 0.144 , means that an increase in dissolved material by 1 mg/cm^2 will lead to an increase in Calcium content by 0.144 g/l
while the coefficient of determination = 0.869 , means that 86% of the variation ( natural ) of calcium content is explainable using the Linear model.
B) Point estimate of true average calcium content
Given that dissolved material = 50 mg/cm^2
= 3.678 + 0.144 * dissolved material
= 3.678 + 7.2 = 10.878
C) Determine an estimate of error standard deviation
Given that ; sum of squares ( SST ) = 320.398
COD ( r ) = 0.86
first; calculate the value of SSE = SST - SST ( r^2 )
SSE = 320.398 - 320.398 ( 0.86) ^2
= 83.43
Finally ; determine the estimate of error standard deviation
S^2 = SSE / n -2
= 83.43 / 23 - 2
∴ S ≈ 1.99
Use the explicit rule given to write the first four terms the sequence
F(n)=n²+7
Answer:
8, 11, 16, 23
Step-by-step explanation:
the rule is: f(n) = n²+7
first 4 terms are:
f(1) = 1² +7 so f(1) = 8
f(2) =2² +7 so f(2) = 11
f(3) = 3² +7 so f(3) = 16
f(4) = 4² +7 so f(4) = 23

A scalar pipeline has 4 pipeline stages A, B, C, D. An operand entering this pipeline must be processed by the four units A-> B -> C -> D. Suppose that units A, B , D takes 2 ns to process an operand, and unit C takes 3 ns to process an operand. How many ns does it take for this scalar pipeline to process 1000 independent operations?
Answer:
The answer is "3006 ns"
Step-by-step explanation:
The time is taken by [tex]a,b, D = 2\ ns[/tex]
taking time [tex]= 3 \ ns[/tex]

From the attached image, we have:
[tex]DE = FG[/tex] -- Opposite, Parallel and Equal
[tex]EF = GD[/tex] -- Opposite, Parallel and Equal

Please answer it. I will give brainliest if its correct..
First find the circumference of the circle:
Circumference = 2 x radius x pi
Circumference = 2 x 4 x 3.14 = 25.12 cm
Now arc ML is 100 degrees.
Multiply the circumference by the arc degree/360 ( 360 is a full circle)
25.12 x 100/360 = 6.98 cm
The answer is 6.98 cm
