Answer:
Yes, it is
Step-by-step explanation:
Given
[tex]Number = 78[/tex]
Required
Determine if it is a multiple of 6 or not
A number is a multiple of 6 if and only if it can be divided by 6 without remainder.
Can 78 be divided by 6?
To check, we have:
[tex]Check = \frac{78}{6}[/tex]
[tex]Check = 13[/tex]
The result of the division has no remainder.
Hence, it is a multiple of 6
Anne is choosing a contractor. She has narrowed down her selection to two
companies and will base her decision on the likelihood that the job is done on
time and on budget. She uses online reviews to estimate the probabilities.
Which contractor should Anne choose to maximize the probability that the job will be done on time and on budget? Assume all events are independent.
Answer: A. Contractor A. The probability that both conditions are met is 0.93
Step-by-step explanation:
Probability of two independent events happening can be found by multiplying them.
Probability of A doing the job on time and on budget:
= Probability that job is done on time * Probability it is done on budget
= 0.97 * 0.96
= 0.93
Probability of B doing the job on time and on budget:
= 0.93 * 0.98
= 0.91
Contractor A has the better probability at 0.93 so should be chosen.
7. Write an equation of the line that passes through the points (1, 4) and (-2, 10), in point-slope form.
Answer:
y = -2x + 6
Step-by-step explanation:
This has sort of the same concept as your earlier question
Use the equation y = mx + b
To find the slope, take the second y value and subtract the first y value. Then take the second x value and subtract the first x value. Divide the answers. You'd get -2 in this case. -2 would be your slope (m).
The substitute any set of x and y values (either (1, 4) or (-2, 10)) and the slope into y = mx + b. You'd get 6 as your y-intercept (b).
What does
-2 indicate about the position of -
and -2 on the number line? (1 point)
>
- is located on the right of-2
O-is located on the left of -2
O - s located on the right of 0 and -2 Is located on the left of 0
is located on the left of0 and -2 is located on the right of 0
Answer:
A. -⅗ is located on the right of -2.
Step-by-step explanation:
-⅗ > -2 means -⅗ is greater than -2. This implies that, on a numberline, -⅗ is closer to 0 than -2.
-¾ and -2 are both located left of 0.
However, -⅗ which is closer to 0 than -2, would be located on the right of -2.
What is the equation of the line in slope-intercept form?
Answer:
y = x +3
Step-by-step explanation:
Line is passing through the points (0, 3) & (1, 4)
Slope of line m= 4-3/1-0 = 1/1 = 1
Required equation of line is given as:
y - 3 = 1(x - 0)
y - 3 = x
y = x +3

A cube with a volume of 64 cubic meters is scaled by a factor of 5. What is the volume of the
modified cube in cubic meters?
Answer:
8,000 m^3
Step-by-step explanation:
The computation of the volume of the modified cube in cubic meters is shown below:
Given that
Volume = 64 m^3
So each side would be
= ∛64
= 4
Now each side is scaled by 5 so each side would be
= 4 × 5m
= 20m
Now the volume of the modified cube is
= 20^3
= 8,000 m^3
Answer:
8,000
Step-by-step explanation:
When the sides of the cube are scaled by a factor of k, the volume increases by a factor of k3. Here, the new volume is 64 cubic meters × 53 = 8,000 cubic meters.

help with those 3 please.. ty
z varies jointly as x and y. z=60 when x=5 and y=6. find z when x = 7 and y=3
Answer:
z = 42
Step-by-step explanation:
The question can be answered in 2 steps as follows:
Step 1: Calculation of the constant of the variation
The equation for the joint variation can be given as follows:
z = cxy ................... (1)
Where;
z = 60
c = constant = ?
x = 5
y = 6
Substituting the values into equation (1) and solve c, we have:
60 = c * 5 * 6
60 = c * 30
c = 60 / 30
c = 2
Step 2: find z when x = 7 and y = 3
Since from Step 1 c = 2, we now use equation (1) and substitute the values into it to find z as follows:
z = 2 * 7 * 3
z = 42
In the problem we’re supposed to find the value of x that makes ABC ~ RST I can’t figure it out can someone please help
Answer:
Step-by-step explanation:
if the triangles are similar then their sides are in proportion ( or you can think that they make equivalent fractions like 2/3 = 4/6 )
44/ (x+2) = 20/7 = 3x+1 /5 ( all of those are equivalent fractions)
use that [tex]\frac{a}{b} =\frac{c}{d}[/tex] is the same as a*d = b*c
[tex]\frac{44}{x+2} =\frac{20}{7}[/tex] is the same as 20(x+2) = 7*44
20x +40 = 308; subtract 40 from both sides
20x = 268; divide by 20 both sides
x= 13.4

Answer:
Option BStep-by-step explanation:
Definition of constants: Contants are numbers that have no variables.
To find the constants of the expression 7r - 3 + 2s + 5, simply look for numbers without variables. We can see that the constants are -3 and 5, which matches Option B.
Hence, Option B is correct.
what is the unit rate of 56 ounces for every 2 cans
Answer:

What is Division?
A division is a process of splitting a specific amount into equal parts.
A unit rate means a rate for one of something.
We need to find the unit rate of 56 ounces for every 2 cans
To do this we need to divide Fifty six ounces with two.
56/2
Fifty six divided by two.
We get Twenty eight.
Hence 28 is the unit rate of 56 ounces for every 2 cans

Problem 2 Find all the divisors of the number 2,310. How do you know that you found them all?
9514 1404 393
Answer:
1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,
55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310
Step-by-step explanation:
The trailing digit is 0, and the sum of digits is 6, so we know the number is divisible by 2, 3, 5. Dividing out those factors, we get a quotient of 77, which is 7×11. This means the prime factorization is ...
2×3×5×7×11 = 2310
There are 5 prime factors, each with an exponent of 1, so the total number of divisors is 2^5 = 32. We will have found them all when all 32 are listed.
1, 2, 3, 5, 6, 7, 10, 11, 14, 15, 21, 22, 30, 33, 35, 42,
55, 66, 70, 77, 105, 110, 154, 165, 210, 231, 330, 385, 462, 770, 1155, 2310
Of course, the pairwise products working toward the center from the ends of the list are all 2310.

how do you find the slope of (2,20)(4,40)(6,60)
9514 1404 393
Answer:
slope = 10
Step-by-step explanation:
Examination of the values shows you that each y-value is 10 times the corresponding x value. That means the slope is 10. (If the ratios were different, then the slope formula would need to be used. The fact that they are all the same means y is proportional to x.)
__
You can use the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (40 -20)/(4 -2) = 20/2
m = 10
The slope is 10.
Which two terms can be combined in this expression?
6 + 3.2 m + two-fifths n minus StartFraction m over 5 EndFraction
6 and 3.2 m
3.2 m and Negative StartFraction m over 5 EndFraction
