Step-by-step explanation:

THe x intercept is where y=0

to solve this we can just plug in 0 for y and solve for x

we have

0= 385-35x

35x=385

x=11

Answer:

Step-by-step explanation:

We can write the similarity statements by naming vertices in order of increasing numbers of arcs, starting with the one having a single arc. Then we can express the side lengths as a reduced ratio, in the same order.

1. JKLM ~ QRSP

  JK : KL : LM : MJ = 20 : 15 : 24 : 25

  QR : RS : SP : PQ = 12 : 9 : 14.4 : 15 = 20 : 15 : 24 : 25 (same ratios)

The scale factor is 12/20 = 0.6.

__

2. ΔABC ~ ΔUVT

  AB : BC : CA = 16 : 14 : 12 = 8 : 7 : 6

  UV : VT : TU = 24 : 21 : 18 = 8 : 7 : 6 (same ratios)

The scale factor is 24/16 = 1.5.

Answer:

27

Step-by-step explanation:

3(6)=18

18+9=27

Answer:

27

Step-by-step explanation:

You would use PEMDAS to solve this equation, P (parenthesis) E (exponates)  M (multiply) D (divide) A (add) S (subtract). The way you use this is by following the steps in the order that you would spell PEMDAS, so 3x+9 would be 3•6+9. So look at the equation 3•6+9, so what would we use first? do we have parenthesis? No, Do we have exponents? No, Do we have multiplication?  Yes, so multiply 3 and 6 = 18. Now the equation will look like this 18+9 = 27.

Hope this helps!

Answer:

C.8.5

Step-by-step explanation:

Answer:

See explanation

Step-by-step explanation:

8x = 3y + 38  

24= 6y + 9x  

Rearrange;

3y - 8x = -38       * 2     -------(1)

6y + 9x = 24       * 1       -------(2)

6y - 16x = -76    -------(3)

6y + 9y  = 24    -------(4)

Subtract (4) from (3)

     -25y = -100

      y= 100/25

     y = 4

Substitute y =4 into(1)

3y - 8x = -38    

3(4) - 8x = -38

12 -8x = -38

-8x = -38 - 12

x = 50/8 = 6 2/8

2) 6 = 2x + y

7x = 3 - 3y

Rearrange;

2x + y = 6            * 3    --------(1)

7x + 3y = -3         * 1     --------(2)

6x + 3y = 18        ---------(3)

7x  + 3y = -3        ---------(4)

Subtract (4) from (3)

-x   = 21

x = -21

Substitute x = -21 into (1)

2x + y = 6

2(-21) + y = 6

-42 + y = 6

y = 6 + 42

y = 48

3)  

11x = 5 + 10y

7y = -2x +45

Rearrange

11x - 10y = 5          * 2  ---------(1)

2x + 7y   = 45       * 11  ---------(2)

22x - 20y = 10     --------(3)

22x + 77y = 495  --------(4)

Subtract (4) from (3)

       -97y  = -485

          y =  5

Substitute y =5 into (1)

11x - 10y = 5  

11x - 10(5) = 5

11x - 50 = 5

11x = 5 + 50

11x = 55

x = 55/11

x = 5

Answer:

A. 16 times of 1/2 inch of rain

Step-by-step explanation:

24 hours = 1440 minutes

90 minutes = 1/2 inch of rain

1440 divided by 90 = 16

16 times of 1/2 inch of rain

I'll do the first 6 rows to get you started.

===========================================

In row 1, we have the number [tex]2^3[/tex] which is the same as writing 2^3

The base is 2 and the exponent is 3. Think of "base" as in "basement" to remember that the base is under the exponent. The exponent tells us how many copies of the base to multiply out. In this case, we have three copies of the base "2" multiplied to get 2*2*2 = 8

============================================

In row 2, we have the number 3^2. The base is 3 and the exponent is 2.

We can say 3^2 = 3*3 = 9. We have two copies of the base multiplied. Think of a 3 inch by 3 inch square that has area of 9 square inches.

============================================

Row 3:

The number 5^4 means 5^4 = 5*5*5*5 = (5*5)*(5*5) = 25*25 = 625

The base is 5 and the exponent 4 tells us how many copies of the base to multiply.

============================================

Row 4:

We aren't given the number like in the earlier rows. But we can see that the base is 6 and the exponent is 2. So the number to fill in that first blank is 6^2

The expanded notation would be 6*6 because the exponent tells us how many copies of the base to multiply out.

The standard notation is 36 because 6*6 = 36.

============================================

Row 5:

This time we don't have an exponent, but we have the base and we have the expanded notation.

The expanded notation of 8*8*8 means the base is 8 and the exponent is 3

So 8^3 = 8*8*8 = 512

We'll have 8^3 to fill in the first blank of row five, 3 fill in the next blank, and finally 512 fill in the last blank.

============================================

Row 6:

We have six copies of '9' multiplied together

This tells us we have the number 9^6. The base is 9 and the exponent is 6

Use your calculator to determine that 9^6 = 9*9*9*9*9*9 = 531441

============================================

I'll let you do the rest of the remaining rows.

Two decimals with a product close to 6.3 are, 2.5 and 2.52

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

To find Two decimals with a product close to 6.3.

Now, Let one decimal number is, 2.5

Hence, Second number is,

⇒ 6.3 / 2.5

⇒ 2.52

Hence, Two decimals with a product close to 6.3 are, 2.5 and 2.52
