The sum of 16 and a number x is equal to 20

Answers

Answer 1

" the sum " means add

16 + x = 20 <= ur equation
x = 20 - 16
x = 4 <== the number

Answer 2

The sum of 16 and 4 is equal to 20.
This is how I know:
20-16=4
How do I know this?
Sum means to add. To get the sum of something that equals another number, you must see what number adds up with 16 to get 20. So, this means that 16+4=20.

(for the first question) False, because sometimes when a number ending in 6 is halved, the last number can be an 8. For example, 56 halved is 28.

(for the second one) False; not all numbers ending in 3 are prime since some numbers like 63 have factors of 3 and 21.

Bill, bob, and barry are hired to paint signs. in 8 hours bill can paint 1 sign, bob can paint 2 signs, and barry can paint 1 and 1 / 3 signs. they all come to work the first day, but barry doesn't like the job and quits after 3 hours. bob works half an hour longer than barry and quits. how long will it take bill to finish 2 signs they were supposed to paint?

Answers

Define rates at which the individuals paint.
Bill: x = 1/8 signs/h
Bob: y = (2 signs)/(8 h) = 1/4 signs/h
Barry: z = (4/3 signs)/(8 h) = 1/6 signs/h

The job is to paint 2 signs, working together.

In the first 3 hours, the amount painted is
(x+y+z signs/h)*(3 h) = (1/8 + 1/4 + 1/6)*3 = 13/8 signs
Remaining: 2 - 13/8 = 3/8 signs

Barry quits.
In the next 1/2 hour (30 minutes), the amount painted is
(x + y signs/h)*(0.5 h) = (1/8 + 1/4)*0.5 = 3/16 signs
Remaining: 3/8 - 3/16 = 3/16 signs

Now Bob quits.
The time for Bill to finish the job is
(3/16 signs)/(1/8 signs/h) = 3/2 h

Answer: Bill finishes the job in 1.5 hours (or 1 hour, 30 minutes)

It will indeed take Bill 1.5 hours to finish the remaining [tex]$ \frac{3}{16} $[/tex] signs.

Work done by Bill, Bob, and Barry collectively take the working efficiency in a defined time interval.

Barry's work in 3 hours:

[tex]$3 \times \frac{1}{6} = \frac{3}{6} = \frac{1}{2} \text{ sign}$[/tex]

Bob's work in 3.5 hours:

[tex]$3.5 \times \frac{1}{4} = \frac{7}{8} \text{ sign}$[/tex]

Bill's work for the same time until Bob leaves (3.5 hours):

[tex]$3.5 \times \frac{1}{8} = \frac{3.5}{8} = \frac{7}{16} \text{ sign}$[/tex]

Total work done by all three in the first 3.5 hours:

[tex]\[ = \frac{1}{2} + \frac{7}{8} + \frac{7}{16}\\= \frac{8}{16} + \frac{14}{16} + \frac{7}{16} \\= \frac{29}{16} \text{ signs} \][/tex]

Remaining work to be done:

[tex]\[ = 2 - \frac{29}{16} \\= \frac{32}{16} - \frac{29}{16} = \frac{3}{16} \text{ signs} \][/tex]

Time for Bill to complete remaining work:

Bill’s rate: [tex]$ \frac{1}{8} \text{ signs per hour}$[/tex]

Time to paint [tex]$ \frac{3}{16} \text{ signs}$:[/tex]

[tex]\[ =\frac{\frac{3}{16}}{\frac{1}{8}} \\= \frac{3}{16} \times 8 = \frac{24}{16} = 1.5 \text{ hours} \][/tex]

Thus, It will indeed take Bill 1.5 hours to finish the remaining [tex]$ \frac{3}{16} $[/tex] signs. This confirms that the correct answer is 1.5 hours.

Rewrite 56 + 32 as the product of the GCF and a sum.

Answers

56 + 32 = 8(7 + 4)

hope it helps

Final answer:

To rewrite 56 + 32 as the product of the GCF and a sum, calculate the GCF, which is 8. Then, express the sum as 8 times the sum of the numbers obtained by dividing 56 and 32 with the GCF. The rewritten expression is 8 × 11.

Explanation:

To rewrite the expression 56 + 32 as the product of their greatest common factor (GCF) and a sum, we first need to find the GCF of 56 and 32. The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. The factors of 32 are 1, 2, 4, 8, 16, and 32. The common factors are 1, 2, 4, and 8. The largest common factor is 8, which is the GCF.

Next, we divide both 56 and 32 by the GCF to find the other factor:

56 ÷ 8 = 7

32 ÷ 8 = 4

Now, we represent the original sum as the product of the GCF and the sum of the results from the division:

56 + 32 = 8 × (7 + 4)

When we simplify the sum inside the parentheses, we get:

8 × 11

Therefore, the expression rewritten as the product of the GCF and a sum is 8 × 11.

The figure is a parallelogram. One diagonal measures 28 units. Is the figure a rectangle? Explain.

A. No, it is not a rectangle because the diagonals are congruent.
B. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.
C. Yes, it is a rectangle because the diagonals are congruent.
D. Yes, it is a rectangle because the sides of the parallelogram do meet at right angles.

Answers

Answer:

(B)

Step-by-step explanation:

From the given figure, we can see that the opposite sides of the given quadrilateral are congruent but they do not meet at right angles because there is no right angle marked on the given figure, thus the given quadrilateral cannot be rectangle (by the definition).

Therefore, No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.

Also, only one diagonal of measure 28 is given, no other diagonal is given, thus rest of the options do not hold.

Number 1. Write an explicit formula for the nth term. Correct answer will get brainliest

Answers

Since the 11th term is 78 and the difference is -9, that means when we go down terms we add 9 and if we go up terms we subtract 9. Since 11-1=10, we can multiply 9 by 10 to get 90 and add that to 78 to get 168 as our first term. Since we subtract 9 for every number from there, we can have 168-9(n-1). We have n-1 due to that the first term is 168, and we want to subtract 9 from each one. If we had it as 168-9n, the second term would be 168-18 when it should be 168-9. We can also add 9 to 168 to get 177 and have it as 177-9n due to that we start at the 0th term. This works due to that we are multiplying -9 by the nth value and adding that to 177

Write a conditional statement. Write the converse, inverse and contrapositive for your statement and determine the truth value of each. If a statements truth value is false, give a counterexample

A conditional statement involves 2 propositions, p and q. The conditional statement, is a proposition which we write as: p⇒q,

Let q be the proposition: The sides of triangle ABC are such that

An example of a conditional statement is : p⇒q, that is:

if Triangle ABC is a right triangle with m(C)=90° then The sides of triangle ABC are such that [tex]|AB|^2=|BC|^2+|AC|^2[/tex]

This compound proposition (compound because we formed it using 2 other propositions) is true. So the truth value is True,

A collection of 30 coins worth $5.50 consists of nickels, dimes and quarters. There are twice as many dimes as nickels. How many quarters are there?

Answers

Let N equal the number of nickels.
Let D equal the number of dimes.
Let Q equal the number of quarters.

We know that .05N + .10D + .25Q = 5.50.
We also know that N + D + Q = 30.
We also know that D = 2N.

Therefore, Q = 30 - (N + D) = 30 - (N + 2N) = 30 - 3N

So...

5.50 = .05N + .10(2N) + .25(30 - 3N)
= .05N + .20N + 7.50 - .75N

Therefore (moving all N's to the left of the equals sing, and all constants to the right of the equals sign)...

.5N = 2.

Therefore, N = 4. There are four nickels, eight dimes, and 18 quarters.

Checking our work...
Four nickels is 0.20.
Eight dimes is 0.80.
18 quarters is 4.50.

That sums to 5.50, and is 30 coins.
