The square of a number ending with 9 will end with?
(a) 1 (b) 3 (c) 6 (d) 9​

Answer:

B

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is

difference of 2 sides < x < sum of 2 sides , that is

17 - 10 < x < 17 + 10

7 < x < 27

In terms of AC , then

7 < AC < 27 → B

Answer:

all u need to know is that a side of a triangle is always smaller ( not smaller or equall) than the sum of two other sides of the triangle which in this case means AC is smaller than 27 and the only choice that is meantioning this is B so yea thats it (u cab always eleminate options if u dont know eveythibg about question but u just know some of them are wrong for some reason)

Answer:

  t = (u -v)/2

Step-by-step explanation:

Observe what is done to t:

Undo these operations, starting with the last one and working up the list.

  [tex]u = v+2t \qquad\text{given}\\\\u-v=2t \qquad\text{undo addition by subtracting $v$}\\\\\dfrac{u-v}{2}=t \qquad\text{undo multiplication by dividing by 2}\\\\\boxed{t=\dfrac{u-v}{2}}[/tex]

Answer:

[tex]u = v + 2t \\ u - v = 2t \\ t = \frac{(u - v)}{2} [/tex]

Answer:

angle XYW = -20x + 155

Step-by-step explanation:

angle XYZ = 150

angle WYZ = 20x - 5

angle XYW = y

angle XYZ = 20x - 5 + y

150 = 20x - 5 + y

150 + 5 = 20x + y

y = -20x + 155

So angle XYW = -20x + 155

Step-by-step explanation:        

Answer:A) 2 months

Step-by-step explanation:The base fee is $20.

The monthly rate is $30.

We can represent the number of months with the variable ‘x’.

The equation for this problem would look like this: 20+30x=80l

In words, it would be: base fee + monthly rate*x = $80

A music shop charges a deposit of $20, plus a monthly rate of $30 to rent an instrument. For how many months did Avi rent an instrument. For how many months did Avi rent an instrument if he spent a total of $80

A) 2 months

B) 3 months

C) 4 months

D) 5 months

Answer:

He can buy 2857 cars.

Step-by-step explanation:

In order to find the amount he can buy, you need to divide 1,000/.35. This equals 2857.14 but because you cannot buy .14 of a toy car, you round down to 2857 which is the end answer. Hope this helps :)

Answer: 2857 cars

Answer:

Length of the bush after 2 months = 60 cm

Step-by-step explanation:

When the bush was planted in the garden, height of the bush = 20 cm

200% as tall as initial length = 2 times of the initial length

300% as tall as initial length = 3 times of the initial length

Therefore, after 2 months, length of the bush = 20 × 3

                                                                            = 60 cm

After 2 months, length of the bush is 60 cm.

Answer:

  54

Step-by-step explanation:

Let d represent the number of donuts. The cost is proportional to the number, so we have ...

  d/33.00 = 9/5.50

  d = 33.00(9/5.5) = 9·6 = 54

You can buy 54 donuts for $33.00.

Answer:

18π[tex]cm^{2}[/tex]

Step-by-step explanation:

Firstly we will have to find the area of the whole circle so we do....

[tex]A_{circle} =[/tex] π[tex]r^{2}[/tex]

[tex]A_{circle} =[/tex] [tex]9^{2}[/tex]π

[tex]A_{circle} =[/tex] 81π[tex]cm^{2}[/tex]

If we are talking about a whole circle the angels in the middle will be equal to 360°. But in our case we are only talking about 80° out of 360°. In other words we have to find out the area what  [tex]\frac{80}{360}[/tex] (in other words [tex]\frac{2}{9}[/tex] )from the whole area is equal to. So we do....

81π[tex]cm^{2}[/tex] x [tex]\frac{2}{9}[/tex] = 18π[tex]cm^{2}[/tex]

Answer:

We conclude that using the property of exponents, we need to multiply 10² to get 10⁴.

Step-by-step explanation:

Let 'x' be the number we need to multiply 10² by to get 10⁴.

So the expression becomes

[tex]10^2\:\times\:x\:=\:10^4[/tex]

Divide both sides by 10²

[tex]\frac{10^2x}{10^2}=\frac{10^4}{10^2}[/tex]

[tex]\:x=\frac{10^4}{10^2}[/tex]

Apply the exponent rule:

[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]

so the expression becomes

[tex]x=\frac{10^4}{10^2}=10^{4-2}[/tex]

          [tex]x=10^2[/tex]

Therefore, we conclude that using the property of exponents, we need to multiply 10² to get 10⁴.

Answer:

it will take 20 hours for 18 bakers to complete the same order

Step-by-step explanation:

15 bakers  take 24 hours

18 bakers take x hours

15 * 24 = 360 "baking hours"

18 * x = 18x " baking hours"

360 baking hours = 18x baking hours

360 = 18x

 18      18

20 = x

x = 20 hours

Answer:

2

Step-by-step explanation:

Round the divisor to the nearest 10 or 100, depending on how many digits are in the divisor.

Round the dividend to the nearest 10, 100, or 1,000 so that all of the digits, except the first one are zeros.

Divide 600 by 30.

Compare your estimate to the exact answer to determine if the exact answer is reasonable.

Answer: The function of company A.

Step-by-step explanation:

For a linear equation:

y = a*x + b

the rate of change is "a", the coefficient that is multiplicating the variable.

Now, for company A we know that:

There is a fixed fee of $50, and $150 for each day.

So if you rent the car for x days, the total cost will be:

y = $150*x + $50

Then for this company, the rate of change is $150.

For company B we have the function:

y = $50*(2x + 1)

Where again, x is the number of days that you rent the car.

We can rewrite this as:

y = $50*2*x + $50*1

y = $100*X + $50

In this case, the rate of change is $100

Then the company with a great rate of change is the function for company A.
