answer the question pls xx

Answer:

Assuming the covered digits are _

The sum is 826.

243 + 1_7 + _26 = 826

The objective is to determine the sum of the two unknown digits

So; we need to think about what number can we add put in 1_7 to determine the covered digit in  _26

From ; 1_7 , we have the choice to pick from 0 - 9

Assuming the covered digit is 0; let's check if we are right

So; 243 + 107  +  _26 = 826

350 +   _26 = 826

_26 = 826 - 350

_26 = 476

So; the covered digit is in the position of 4 , but it doesn't tally together

i.e 426 is not the same as 476, which makes our assumption to be wrong.

Let consider the covered digit to be 5 for example.

So; 243 + 157  +  _26 = 826

400 +   _26 = 826

_26 = 826 - 400

_26 =  426

The covered digit is in the position of 4

SO;

426 = 426

Here , our assumption is right.

As such , the covered digits are 5 and 4

The sum of the two  covered digits are = 5 + 4 = 9

Answer:

$135

Step-by-step explanation:

10% of 150 = 15

150 - 15 = 135

Increased by 10%.

So, 150 x 0.10 = 15

The necklace was increased by £15.

The price before the increase is £150 - £15.

This amount is £135.

Answer:

kate spent $9.95 dollars on the book

Step-by-step explanation:

Answer: She spent $9.95 on the book. $28.00 - $18.05 = 9.95

Answer:

70+95

70=2*5*7

95=5*19

70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)

5*33=165 and 70+95=165 also

Answer:

70+95

70=2*5*7

95=5*19

70+95=(5*2*7)+(5*19)=(5*14)+(5*19)=5*(14+19)=5*(33)

5*33=165 and 70+95=165

Answer:

The equation is: 20 + 4.5h = 11 + 5.75h

The total cost of the services will be equal at 7.83 or 8 hours.

Step-by-step explanation:

This equation is correct because it shows that these two scenarios equal the same amount of money when there is a certain amount of hours, or "h."

Here is how we solve the equation;

20 + 4.5h = 11 + 5.75h <-----Here is the original equation.

Service A                                                        Service B

1. 20 - 20 + 4.5h                         =               11 - 20 + 5.75h

2.4.5h - 5.75h =  -1.15h                             -9 + 5.75h/5.75 =

3. -1.15h/-1.15 = h                                              9/-1.15 = 7.83

                  h = 7.83 or 8 hours when rounded to the nearest hour

Answer:

What is the cost of 1 hotdog?

Answer: $4.50

How many hotdogs can you buy for $18?

Answer: 4

Step-by-step explanation:

If $27 can buy you 6 hot dogs, to find the cost of one, we just divide.

27 divided by 6 = 4.5 ($4.50)

So 1 hotdog costs $4.50

If 1 hotdog is $4.50, and we want to know how much we can buy for $18, then we divide again.

18 divided by 4.5 = 4

So for $18, we can buy 4 hotdogs

Answer:

a.  -0.01 < x - 8 < 0.01

b.  7.99 < x < 8.01

c.  see attachment

d. Bolt has to be greater than 7.99 mm and less than 8.01 mm to be within the margin of error of 0.01 mm.

Step-by-step explanation:

-0.01 < x - 8 < 0.01

-0.01 < x - 8   and   x - 8 < 0.01

7.99 < x                     x < 8.01

Write this as:   7.99 < x < 8.01

On graph the 7.99 and 8.01 are very near to each other and represented via open red circle.

Answer:

b. is 7.99 < x < 8.01

Answer:

No, because it fails the vertical line test ⇒ B

Step-by-step explanation:

To check if the graph represents a function or not, use the vertical line test

Vertical line test: Draw a vertical line to cuts the graph in different positions,

In the given figure

→ Draw vertical line passes through points 2, 6, 7 to cuts the graph

∵ The vertical line at x = 2 cuts the graph at two points

∵ The vertical line at x = 6 cuts the graph at two points

∵ The vertical line at x = 7 cuts the graph at one point

→ That means the vertical line cuts the graph at more than 1 point

   in some positions

∴ The graph does not represent a function because it fails the vertical

   line test

Answer:

Rs 120

Step-by-step explanation:

Let MP = m

Discount = 25% of MP = m/4

SP = MP - Discount

= m - m/4 = 3m/4

If profit is 20%, CP = 3m/4 x 100/120 = 5m/8

=> Profit = 3m/4 - 5m/8 = m/8

Given Profit - Discount = Rs 15

=> |m/8 - m/4| = 15

m/8 = 15

m = Rs 120

When you substitute

y: 11

x: -2

Substitute:

y=x+13

11=-2+13

11=11

This is always true.

Step-by-step explanation:

Imagining living a life for five hundred years in the future, can have two perspectives considering the reality of today's society.

Let us suppose that we currently overcome all challenges related to preserving the environment, sustainable consumption, violence, and racial discrimination. Well, considering that point of view, a typical day five hundred years from now would be a lot of fun, I imagine that we would have great biodiversity preservation centers, people would be more cordial with others, everyone would have access to education and essential rights, and we would use more bicycles as a means of transport, because even if they had already managed to invent teleportation, the bicycle would still be a good option for the practice of physical exercises.

Answer:

$332.55

Step-by-step explanation:

In order to figure our Cliff Alsworth's average monthly spendings on utilities, we need to add the amount he's spent each month, and divide it by the amount of months he bought utilities.

369.75 + 330.90 + 287.00 = 997.65

997.65 / 3 = 332.55

Therefore, the average Cliff's average payment for utilities is $332.55 per month. Hope you ace your test! :)

Step-by-step explanation:

2010.2/380= 5.29

Answer:

5.29  = 20.102 / 3.8.

Step-by-step explanation:

529 × 3.8 = 2010.2

So 529 = 2010.2 / 3.8

We need 5.29 on the left so we divide both sides by 100:

5.29 = 2010.2 / (3.8*100)

5.29  = 20.102 / 3.8

Answer:

120 Kg : 72 Kg

Step-by-step explanation:

Sum the parts of the ratio, 5 + 3 = 8 parts

Divide the quantity by 8 to find the value of one part of the ratio.

192 Kg ÷ 8 = 24 Kg , thus

5 parts = 5 × 24 Kg = 120 Kg

3 parts = 3 × 24 Kg = 72 Kg

192 Kg = 120Kg : 72 Kg in the ratio 5 : 3

Answer:

x = 3

y = 4

Step-by-step explanation:

3x -4y = -7

4x + 3y = 24

write the first equation in terms of y

3x - 4y = -7

3x + 7 = 4y

3x/4 + 7/4 = y

now substitute that into the second equation

4x + 3y = 24

4x + 3(3x/4 + 7/4) = 24

4x + 2.25x + 5.25 = 24

6.25x + 5.25 = 24

6.25x = 24 - 5.25

6.25x = 18.75

x = 18.75/6.25

x = 3

last step, substitute x for 3 in the equation.

y = 3x/4 + 7/4

y = 3*3/4 + 7/4

y = 9/4 + 7/4

y = 4

Answer:

10^100 is larger than 100^10.

Step-by-step explanation:

10^100 compared to 100^10, we have 10^100 greater. 100^50 would equal to 10^100, as 10^2=100. 10^100 would be much more than 100^10.

[tex] \sqrt{ {2}^{2} \times 6 } [/tex]

[tex] \sqrt{ {2}^{2} } \sqrt{6} [/tex]

[tex] \sqrt{ {2}^{2} } = |2| = 2[/tex]

[tex] = 2 \sqrt{6} [/tex]

Answer:

2√6

Step-by-step explanation:

Because 2 multiplied by itself is 4

4 times 6 is 24

You multiply 2 by itself is because of the square root

Square roots are the opposite of exponents

Just like how addition is the opposite of subtraction

2^2 is 4

√4=2

Since 24 has a 4 in its multiple you can simplify it into 2 and put it on the outside
