Answers
Answer:
1: C) Yes, because the last digit is 6, which is divisible by 2
2: B) Yes, because the sum of 2+1+6=9, which is divisible by 3
3: C) Yes, because the last digit of the number is 0
Step-by-step explanation:
Let's start with the first one. Is 26 divisible by 2? Yes, it is, because the last digit is 6, which is divisible by 2. To check to make sure we are right, we simply divide 26 by 2. Can it be done? Yes, 26 divided by 2 is 13, so we are right.
What about number two? Is 216 divisible by 3? Well, the rules divisiblity rules change for 3. For three, the sum of the digits of the number must be divisible by three. Do 2, 1, and 6, when added together, equal a number that is divisible by 3? Well, 2+1+6 is 9, and 9 is divisible by three, so the answer is B.
For the last one we need to check the divisibility rule for ten. The rule is that if the number ends in 0, it is divisible by 10. Does 40,100 end in a zero? Yes, so the answer is C.
3-1/8a=1/4
Pleasseeee help
Answers
The goal is to isolate "a" and its coefficient to make the simplification process easier.
Start by subtracting 3 from both sides:
3 - 3 - 1/8a = 1/4 -3
-1/8a = 1/4 - 3
Next, multiply 3 by 4/4 to convert it into a fraction:
-1/8a = 1/4 - [3 • (4/4)]
-1/8a = 1/4 - 12/4
-1/8a = - 11/4
Multiply both sides by -8:
(-8) -1/8a = - 11/4 (-8)
a = 88/4 = 22
Therefore, a = 22.

Answers
the first 3 is in the tenths place, the second 3 is in the hundredths place, the 2 is in the thousandths place, and the 5 is in the ten thousandths place.
now since you know that the 3 is in the tenths place you have to look at the number in the hundredths place so you know what to round it to. since the number in the hundredths place is below 5, it stays the same. if it were a 5 or above, that 3 would be rounded to a 4 making the answer 75.4, but since it’s a 3, the answer stays 75.3

Answer:

Step-by-step explanation:
14/0.7
Answer:
Step-by-step explanation:
Your question: 70 percent of what number equals 14?
Step 1: Multiply both sides by 100 to get 7,000 and 1,400.
Step 2: Divide both sides by 70 to get 100 and 20.
Step 3: Put it into fraction form. [tex]\frac{20}{100}[/tex].
Step 4: Since in percentages, you typically only go up to 100, we can remove the 100 to leave us with just 20.
Step 5: We have our answer. 70% of 20 is 14.

Step-by-step explanation:
Correct on edge
The function will be one-to-one only if c = 13.
When a function is one-to-one?
A function is one-to-one if and only if each value in the range appears only once.
So, the given set will represent a one-to-one function if c takes a value that is not repeated in any of the other coordinate pairs.
We have:
(1, 2), (2, 3), (3, 5), (4, 7), (5, 11), (6, c)
For the given options, the only element that not already appears in one of the pairs is c = 13, so that is the correct option.

Which answer choice shows how to find 352 ÷ 16 using partial quotients? Find the quotient and the value that goes in the box in Step 2. Step 1: Subtract (20 × 16) from 352 to get 32. Step 2: Subtract (☐ × 16) from 32 to get 0. Step 3: Add to find the quotient. A. □ = 1; 352 ÷ 16 = 21 B. □ = 1; 352 ÷ 16 = 32 C. □ = 2; 352 ÷ 16 = 22 D. □ = 2; 352 ÷ 16 = 52
Answers
Partial quotient is one of the ways of dividing expressions and numbers.
The value that goes into the box is 2.The quotient is 22.The quotient is given as:
[tex]\mathbf{352 \div 16}[/tex]
The first step is:
[tex]\mathbf{352 - (20 \times 16) = 32}[/tex]
The next step is:
[tex]\mathbf{32 - ([\ ] \times 16) = 0}[/tex]
Represent the blank with x
[tex]\mathbf{32 - (x \times 16) = 0}[/tex]
So, we have:
[tex]\mathbf{32 - 16x = 0}[/tex]
Collect like terms
[tex]\mathbf{16x = 32}[/tex]
Divide both sides by 2
[tex]\mathbf{x = 2}[/tex]
So, the value that goes into the box is 2.
The quotient is then calculated as:
[tex]\mathbf{Quotient = 20 + 2}[/tex]
[tex]\mathbf{Quotient = 22}[/tex]
Hence, the quotient is 22.

Jada has a scale map of Kansas that fits on a page in her book. The page is 5 inches by 8 inches. Kansas is about 210 miles by 410 miles. Select all scales that could be a scale on the map. (There are 2.54 centimeters in an inch.) A. 1 in to 1 my B. 1 cm to 1 km C. 1 in to 10 mi D. 1 ft to 100 mi E. 1 cm to 200 km F. 1 in to 100 mi G. 1 cm to 1000 km
Answers
Step-by-step explanation:
5 inches on the map correspond to 210 miles (or even a bit more) in reality.
we do know, the real length of the state is 213 miles.
and 8 inches to 410 (or a bit more) miles.
but, in fact, in reality, Kansas is indeed 410 miles long.
so, let's see first about the consistency of the scale factors (our ratios) in every direction.
5 inches / 210 miles = 1/42
8 inches / 410 miles = 4/205 = 1/51.25
so, in order to be a true map, both directions must have the same scale factor.
to fit the whole map on one page we must go with the smaller scale ratio : 1/51.25
so,
A with the ratio 1/1 is wrong.
B wrong.
1 cm = 1/2.54 inches
1 km = 1/1.6 miles
so, the scale ratio here is
1 cm / 1km = 1/2.54 / 1/1.6 = 1.6 / 2.54
still far off of the 1/51.25 ratio.
C with the ratio 1/10 is wrong.
D wrong
1 ft = 12 inches
the ratio is therefore
12/100 = 3/25 = 1/8.3333
still far off of the 1/51.25 ratio.
E would fit
1 cm = 1/2.54 inches
1 km = 1/1.6 miles
200 km = 200/1.6
so, the scale ratio here is
1 cm / 200km = 1/2.54 / 200/1.6 = 1.6 / (2.54×200) =
= 1.6 / 508
still far off of the 1/51.25 ratio, but in the form of being much smaller. so it fits on the page.
F would fit.
the ratio is 1/100.
this is again far off of the 1/51.25 ratio, but also in the form of being much smaller, so it fits on the page.
G would fit.
1 cm = 1/2.54 inches
1 km = 1/1.6 miles
1000 km = 1000/1.6
so, the scale ratio here is
1 cm / 1000km = 1/2.54 / 1000/1.6 = 1.6 / (2.54×1000) =
= 1.6 / 2540
again far off of the 1/51.25 ratio, but also in the form of being much smaller. so it fits on the page.

are empty. How many chairs are empty?
Answers
17 rows•28 chars per row=476 chairs total
476 chairs/2(because half are empty)=238 empty chairs.
Answer:
238 chairs are empty
Step-by-step explanation:
Firstly,
you'll have to times 17 by 28 to get the total chairs in the school gym
17 × 28
= 476
Next,
divide it by 2 because half of the gym???
476/2
= 238

Answer:
subtract 20 from both sides
Step-by-step explanation:
1. To find the answer, let's actually try solving the equation first and find the 2nd step.
2. (Solving)
Step 1: Distribute 2 to each term.
[tex](2)(x)+(2)(10)=60[/tex] [tex]2x + 20 = 60[/tex]Step 2: Subtract 20 from both sides.
[tex]2x + 20 - 20 = 60 - 20[/tex] [tex]2x = 40[/tex]3. Since we got that the second step was "subtract 20 from both sides," the answer is subtract 20 from both sides.
