Answer:

15 photos

Step-by-step explanation:

one can start off by first seeing how many photos will be taken on the vacation. We can do that by multiplying the days with how many photos will be taken for each- so 20×7= 140. Then we can take the total amount of photos the phone cam hold-200 subtract what we already have 200-75= 125 thats how much space if left but we need more (140). So the. we can start making quick guesses by taking 5 from 75 and see what we get then taking another 5 and another if needed we get 60 that finally gives when subtracted from 200- 200-60=140 the amount of space we need. Then finally we can just do 75-60 to get the total amount of photos we must delete. 75-60= 15

Answer:

88

Step-by-step explanation:

The actual volume is 87.965

To the nearest tenth would be 88 (the hundreths place would round up the tenths place and it is 9 so .9 is rounded up to 1)

Answer:

y=-4-* and y= 2 x-3

Step-by-step explanation:

Answer:

y = 4^ and y = 2 x - 3

Answer:

x=4

Step-by-step explanation:

First we Divide both sides by 4 so we can just get x

For example

4x=16

x=4  We divided both sides by 4 because we need to get x and the reason why we also divided 16 by 4 is because what you do to one side you do to the other to keep the values  consistent

Answer:

perimeter of this figure is = 54 cm

and area of traingle is = 1/2*base *height

so = 1/2*8*6

=. 24cm*cm

and area of rectangle = length * breadth

area = 112cm*cm

so total area = 112+ 24 = 136cm*cm

hope it helps and your day will full of happiness

Answer:

138 cm^2 = Area .          54 cm = Perimeter

Step-by-step explanation:

Find the area of the triangle-                                   b * h = A

                                                                                     2

                                                                                   8 * 6 = A

                                                                                      2

                                                                                   48/2 = A

                                                                                     24 = A

Find the area of rectangle-                                        l * w = A

                                                                                   16 * 7 = A

                                                                                      112 = A

Add the areas together.                                            24 + 112 = 136 cm^2

Perimeter is adding up all the sides.                         s + s + s + s + s

                                                                                   16 + 7 + 8 + 10 + 13 = 54 cm

Answer:

Bill paid about 7% sales tax.

Step-by-step explanation:

First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.

The answer is 15

Step-by-step explanation:

adding 3 to y for each time 1 is added to y. since you start with a base of 9, we can conclude this answer by taking 3 times 15, which is 45, then adding 9, which makes 54. Like this:

0 | 9

1 | 12

2 | 15

Answer:

Total after tax and discount is $7.78

Step-by-step explanation:

(10.49×0.3)= 3.15

10.49 - 3.15 = 7.34

(7.34×0.06)= 0.44

7.34 + 0.44 = 7.78

Answer:

Step-by-step explanation:

14y-1=11y+17 subtract 11y from both sides

3y-1=17 add 1 to both sides

3y=18, divide both sides by 3

y=6

Since DG=EF

EF=9y+4 and using y=6

EF=9(6)+4

EF=54+4

EF=58

Step-by-step explanation:

Answer:

Step-by-step explanation:

Say you wanted to round the number 838.274. Depending on which place value you'll round to, the final result will vary. Rounding 838.274:

Rounding to the nearest hundred is 800

Rounding to the nearest ten is 840

Rounding to the nearest one is 838

Rounding to the nearest tenth is 838.3

Rounding to the nearest hundredth is 838.27

Basic Rules of Rounding

When you "round to the nearest _____" regardless of what goes in the blank the steps are nearly always the same:

Identify which place value you are rounding to. The smaller the place value, the more accurate the final result will be.

Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place.

If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number (including the next smallest place value you just looked at) become zeros, or drop-off if they're located after the decimal point. This is called rounding down.

If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one (+1). Just like before, any remaining digits before the decimal point become zeros, and any that are after the decimal point are dropped. This is called rounding up.

Round to the Nearest Hundred: 3250

Identify the hundreds digit: the 2 in 3250

Identify the next smallest place value: the 5 in 3250

Is that digit greater than or equal to five? Yes, so round up.

Increase the hundreds digit by one, so 2 becomes 3. Every digit after becomes a zero.

3250 rounded to the nearest hundred is 3300

Round to the Nearest Ten: 323.5

Identify the tens digit: the 2 in 323.5

Identify the next smallest place value: the 3 in 323.5

Is that digit greater than or equal to five? No, so round down.

The tens digit stays the same at 2. Every digit after becomes a zero. Digits after the decimal point are dropped.

323.5 rounded to the nearest ten is 320

Round to the Nearest Ten: 499

Identify the tens digit: the first 9 in 499

Identify the next smallest place value: the second 9 in 499

Is that digit greater than or equal to five? Yes, so round up.

The tens digit increases by one. Since 9+1=10, you need to carry the 1 and add it to the digit in the hundreds place. Each digit after becomes a zero.

499 rounded to the nearest ten is 500

Round to the Nearest Tenth: 0.74

Identify the tenths digit: 7 in 0.74

Identify the next smallest place value: the 4 in 0.74

Is that digit greater than or equal to five? No, so round down.

The tenths digit stays the same at 7. Since the remaining digits are after the decimal point you just drop them.

0.74 rounded to the nearest tenth is 0.7

Round to the Nearest Hundredth: 3.141

Identify the hundredths digit: the 4 in 3.141

Identify the next smallest place value: the second 1 in 3.141

Is that digit greater than or equal to five? No, so round down.

The hundredths digit stays the same at 4. Drop the digits to the right of 4.

3.141 rounded to the nearest hundredth is 3.14

Answer:

68 +76

So we do 144/2=72

Answer: I believe its D

The 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain option (D) is correct.

Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.

We have:

The total length of the necklace chain = 400 mm

Alice put 40 Nos 1.7 mm beads

Length for this = 40×1.7 = 68 mm

Alice put 27 Nos 6.5 mm beads

Length for this = 27×6.5 = 175.5 mm

Alice put 8 Nos 3.4 mm beads

Length for this = 8×3.4 = 27.2 mm

Total length occupied = 68+175.5+27.2 = 270.7 mm

The length of 400 mm chain is left = 400 - 270.7 = 129.3 ≈ 129 mm

Thus, the 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain.
