B. A worker who works 40 hours is paid $1700.
C. There are 40 workers who are paid $1700 per month.
D. A worker with 40 hours of training is paid $1700 per month
Answer:
d.
Explanation:
Look at the title of the categories in the chart. 40 is categorized under “hours of training,” meaning 40 hours of training. 1700 is categorized under “monthly pay.” Put the information together and it means $1,700 for 40 hours that month.

equivalent to One-fourth x is One-half x + one-half x; equation 7 is correct
what is equivalent expression?Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same. The given equation is equivalent to the expression one half and one half x.
Given information;
The expression given in the problem is,
(1/4) x [tex]x[/tex]
Equivalent expression;
Equivalent expression is the expression of two equation when the way of representation of the two equation is different but the result is same.
For given expression,
1/4 x [tex]x[/tex]
As the above function is the function of x. Thus it can be written as,
f(x)= 1/4 x [tex]x[/tex]
The number four is the product of number 2 and number 2. Thus,
f(x)=(1/2x2) x [tex]x[/tex]
f(x)=(1/2 x 1/2) x [tex]x[/tex]
Hence the given equation is equivalent to the expression one half and one half x.

c² = 4² + 3²
Evaluate the exponents
c² = 16 + 9
Evaluate the sum
c² = 25
Take the positive square root of both sides
c = 5

Susan Marciano invested part of her 28,000 bonus in a fund that paid a 10% profit and invested the rest in stock that suffered a 3% loss. Find the amount of each investment if her overall net profit was 2,410
Answer:
amount invested in funds that earned 10% is $25,000, while the amount invested in stock that suffered 3% loss $3,000.
Step-by-step explanation:
Let x be the amount invested in funds that earned 10%.
Then the amount invested in stock that suffered 3% loss is 28,000 - x.
The profit from investment in funds is 10%x
The loss from investment in stock is 3%(28,000 - x).
The net profit is 10%x - 3%(28,000 - x).
As the net profit given in the problem is $2410, we have:
10%x - 3%(28,000 - x) = 2410
Solving for x, we have:
10x - 3(28,000 - x) = 241000 (multiply both sides by 100)
10x - 84000 + 3x = 241000
13x = 241000+84000
13x = 325000
x = 325000/13
x = 25,000
So
the amount invested in funds that earned 10% is $25,000.
the amount invested in stock that suffered 3% loss is 28,000 - x = 28000 - 25000 = $3,000.

D. x = 4 + 9
Answer:
x = (k+9)/4
Step-by-step explanation:
4x - 9 =k
Add 9 to each side
4x-9+9 = k+9
4x = (k+9)
Divide each side by 4
4x/4 = (k+9)/4
x = (k+9)/4
Answer:
The answer is C
Explanation:
you first add 9 to both sides, you equation will then be 4x = k+9
you then divide both sides by for to get rid of the four from the left side, that will leave you with the equation of x = k+9 over 4

The slope of AB is -2/5. Segments CD has endpoints at C(-5,3) and D(10,-3). Are AB and CD parallel, perpendicular or neither? Justify.
Answer:
AB and CD are parallel
Step-by-step explanation:
AB has the slope of -2/5
lets see what slope the line CD has:
points are (-5, 3) and (10, -3)slope= m= (y2-y1)/(x2-x1)= (-3-3)/(10+5)= -6/15= -2/5as we see AB and CD have same slope, therefore they are parallel

Add 7m/16+(-m/16) . Reduce, if possible.
Plzz answer quickly
Answer:
6m/16 = 3m/8
Step-by-step explanation:
since the fractions have the same denominator, just take out the operation on the numerators of the 2 fractions. So, 7m +(-m).
7m +(-M) is the same as 7m - m, so that is 6,
when you put it back together, you get 6m/16, simplify it to 3m/8

In given Venn diagram describe the shading region is A intersection B or A ∩ B
What is Venn diagram?A Venn diagram is an illustration that uses circles to show the commonalities and differences between things or groups of things Venn diagrams, also called Set diagrams or Logic diagrams, are widely used in mathematics, statistics, logic, teaching, linguistics, computer science and business. Many people first encounter them in school as they study math or logic, since Venn diagrams became part of “new math” curricula in the 1960s. These may be simple diagrams involving two or three sets of a few elements, or they may become quite sophisticated, including 3D presentations, as they progress to six or seven sets and beyond. They are used to think through and depict how items relate to each within a particular “universe” or segment. Venn diagrams allow users to visualize data in clear, powerful ways, and therefore are commonly used in presentations and reports. They are closely related to Euler diagrams, which differ by omitting sets if no items exist in them. Venn diagrams show relationships even if a set is empty.

To prove that ΔABD is congruent to ΔCBD where given that
1.Line segment AB ≅ Line segment CB (Given)
2. Then we can write AD ≅CD ; Given : D is the mid point of AC

5-10 hours
Answer:
So if the company fills in 1/10 of a tank in 1/5 hour. We should multiply by 10
so that means that the tank will be 100% full because 10/10 = 100%
That also means we need to multiply it by 1/5. 1/5*10 = 10/5.
Therefore we get 2 hours.

Linda made 5 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 5 necklaces was $18.50 . If the beads cost $1.50 for each necklace, how much did each pendant cost?
Answer:
$2.20
Step-by-step explanation:
If the beads cost $1.50 for each necklace, then we have to do $1.50 X 5 = $7.50
Then, $18.50 - $7.50 = $11
Then $11/ 5 = $2.2

A file that is 246 megabytes is being downloaded. If the download is 12.5% complete, how many megabytes have been downloaded? Round your answer to the nearest tenth
Answer:
30.8
Step-by-step explanation:
We can mutiply 246 by 0.125 to get the answer.
246 * 0.125 = 30.75 = 30.8
Answer:
30.8 megabytes
Step-by-step explanation:
We know that 12.5% of the 246 megabytes have been downloaded.
Of, means multiply. Therefore, we must multiply 12.5% and 246.
12.5%*246
Convert 12.5% to a decimal. Divide 12.5 by 100, or move the decimal place two spots to the left.
12.5/100=0.125
12.5–> 1.25 —> 0.125
0.125*246
Multiply
30.75
We need to round to the nearest tenth. The 5 in the hundredth place indicates that we must round the 7 in the tenth place up to a 8.
