Answer:

the formula for finding the perimeter of a rectangle is P=2L+2W

an example of how to find the perimeter is

Explanation:

For a rectangle, its perimeter is the sum of all for sides.

The rectangle has a perimeter of 54. Find the lengths of the unknown side. That is, find S.

54=20+20+S+S

Simplify

54=40+2S

Solve for S

14=2S

S=7

Step-by-step explanation:

Answer:

Length=22 cm

Step-by-step explanation:

Perimeter=56 cm

let width=x

According to given condition:

length=4x-2 ...........(A)

Perimeter=2(length+width)

Substitute the values in above formula:

56cm=2(4x-2+x)

56cm=2(5x-2)

56cm=10x-4

(56+4)=10x

60 cm=10x

x=60cm/10

x=6cm

For the value of length :

Substitute the value of x in equation (A):

Length=4x-2

Length=4(6)-2 cm

Length=24-2 cm

Length=22 cm

Answer:

  C.  y = 2x -7

Step-by-step explanation:

You can use any pair of points to find the slope. Use the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-7 -(-13))/(0 -(-3)) = 6/3 = 2

This is the coefficient of x in the slope-intercept form ...

  y = mx +b

The second point (0, -7) tells you that b = -7, so the equation is

  y = 2x -7 . . . . matches C

1 A function is represented by the following set of ordered pairs. {(-3,-13), (0, -7), (3, -1), (6,5)}

Which equation represents the function?

Therefore the answer i letter D.

Answer:

Step-by-step explanation:

~one variable linear equation

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

10x - 7 = 4x + 5

= 10x - 7 - 4x = 5

= 10x - 4x = 5 + 7

= 6x = 5 + 7

= 6x = 12

= x = 12 ÷ 6

= x = 2 ✔️

~ nice to help you ^^

I hope you have your answer now

Explanation:

Draw a straight line from home plate to second base. Two right triangles form. Each triangle has both legs equal to 90 ft. The hypotenuse is what we're after. We'll use the pythagorean theorem to find it.

[tex]a^2 + b^2 = c^2\\\\c = \sqrt{a^2 + b^2}\\\\c = \sqrt{90^2 + 90^2}\\\\c = \sqrt{16200}\\\\c \approx 127.27922\\\\c \approx \boldsymbol{127.3}\\\\[/tex]

It's approximately 127.3 feet from home plate to second base. This is a straight line distance. Any curved path the ball takes will travel a slightly longer distance; however, we only consider the straight line distance for the sake of simplicity.

Answer:

  $87.50

Step-by-step explanation:

To answer this question, you make use of the formula for simple interest:

  I = Prt

This is the interest I on principal amount P at annual rate r for t years.

You have P = $3500, r = 0.025, t = 1, so the interest is ...

  I = $3500×0.025×1 = $87.50

You would receive $87.50 in interest on your savings account.

Additional comment

Many calculators, and all spreadsheets, can use a percentage number directly in the calculation. If yours can't, then you must convert the percentage to a decimal fraction. You can think of the "%" symbol as equivalent to "/100" or "×0.01". The decimal equivalent of 2.5% is 2.5/100 or 2.5×0.01 = 0.025.

__

We have assumed the account earns simple interest, because there is no mention of interest compounding, or of a monthly accounting. In many real-life savings accounts, the interest is computed each month and added to the balance. The computation for the following month includes interest on the interest earned previously. We say the interest is compounded in that case. The formula for compound interest is different from the one shown here.

Answer:

your answer is, -x+5

Step-by-step explanation:

Answer:

x - 5y - 6

Step-by-step explanation:

- 6 + 4y - ( - x + 9y) ← distribute parenthesis by - 1

= - 6 + 4y + x - 9y ← collect like terms

= x - 5y - 6

Answer:

1. Solving for x. Want to solve for y instead?

1 Subtract yy from both sides.

4x=11-y

4x=11−y

2 Divide both sides by 44.

x=\frac{11-y}{4}

x=

Answer:

D. 10 3/8

Step-by-step explanation:

First make them into a improper fraction

[tex]\frac{29}{8} +\frac{27}{4}[/tex]

Find the lowest common denominator:

[tex]\frac{29}{8} +\frac{27*2}{4*2}[/tex]

Multiply the denominators:

[tex]\frac{29}{8} +\frac{27*2}{8}[/tex]

Multiply the numerators:

[tex]\frac{29}{8} +\frac{54}{8}[/tex]

Combine the fractions:

[tex]\frac{(29+54)}{8}[/tex]

Combine the numerators:

[tex]\frac{83}{8}[/tex]

=

[tex]10\frac{3}{8}[/tex]

Hence, D. 10 3/8 is the Correct answer.

Answer:   -4.1 degrees celsius

Step-by-step explanation:

Start at -1.5 on the number line. Then move 2.6 units to the left to arrive at -4.1

Or you can compute -1.5 - 2.6 = -4.1 to get the same result. When we subtract a number from a negative, you are effectively adding the two values and making the final result negative. So, 1.5+2.6 = 4.1 which turns into -4.1

Answer:

  a.  ∞, -∞

Step-by-step explanation:

The line has negative slope, so the sign of the end value of y will be the opposite of the sign of the end value of x.

  x → -∞,  y → ∞ . . . . . off the top of the graph as x goes to the left

  x → ∞, y → -∞ . . . . . . off the bottom of the graph as x goes to the right

The end behavior is summarized as ...

  ∞, -∞ . . . . . matches choice A

Answer:

I can't see the last answer choice.

Answer:

the answer for (9squared divided by 3) - ( 3 x 5 ) = 12

Step-by-step explanation:

(9squared divided by 3) - ( 3 x 5 ) = 12

9x9 = 81

81 ÷ 3 = 27

27 - (3x5)

3 x 5 = 15

27 - 15 = 12

so it goes in the 12 box

4squared - ( 2 x 3 )

4squared = 4 x 4

4 x 4 = 16

16 - (2 x 3)

2 x 3 = 6

16 - 6 = 10

so it goes in the 10 box

Answer:

  1/10

Step-by-step explanation:

The fraction 3/5 can be rewritten as one that has 10 as its denominator.

  [tex]\dfrac{7}{10}+\left(-\dfrac{3}{5}\right)=\dfrac{7}{10}-\dfrac{6}{10}=\dfrac{7-6}{10}=\boxed{\dfrac{1}{10}}[/tex]

Answer:

y - 3 = -12(x - 5)

Step-by-step explanation:

This is what point slope form looks like:

y - y1 = m(x - x1)

(5, 3) is our known point, represented as (x1, y1).

Now, just plug in the given slope and point into the equation:

y - 3 = -12(x - 5)

Think of a number, that when multiplied with itself, will get you 90.

We could try something like 7. So 7*7 = 49, but it's too small.

How about 10? Well we get 10*10 = 100 which is too big. The answer is between 7 and 10.

Let's try 8. So we get 8*8 = 64 which is too small.

This process is repeated until you determine that the answer is somewhere between 9 and 10

9*9 = 81

10*10 = 100

----------------

From here, we can try 9.5 since it's right between 9 and 10

9.5*9.5 = 90.25

close but not quite there. It's a bit too large. So the actual value is somewhat smaller than 9.5

Let's try 9.4

9.4*9.4 = 88.36

That seems even worse off compared to 90.25, so 9.5 is the better answer.

-----------------

As a shortcut, you can use the square root on your calculator

[tex]\sqrt{90} \approx 9.4868 \approx 9.5[/tex]

Answer:

(7, -1) maybe...

Answer:

Line is y = -3x + 3

Slope = -3

y-intercept = 3

Step-by-step explanation:

Slope is the movement up or down, and left or right. Y-intercept is the point in which the line crosses the y-axis. In slope-intercept form (y=mx+b), m represents the slope, while b represents the y-intercept.

So since the line crosses the y-axis at positive 3, that will be the y-intercept. Now if we go from that very same point, and do rise/run, we'd move downwards 3 units and to the right 1 unit, to get our slope of -3/1 (it's written as just -3 though).

So now we plug it in: y = -3x + 3

Hope this helps you :)

Answer:

I don't understand the question but I think the answer is either 10 or 30

Answer:

see below

Step-by-step explanation:

log sqrt5  (25) = y

we know that loga (b) = c  can be rewritten as  a^c = b

sqrt(5) ^ y = 25

Rewriting sqrt(5) as 5^1/2  and 25 as  5^2

5^1/2 ^ y = 5^2

we know a^b^c = a^ (b*c)

5 ^ 1/2y = 5^2

1/2y = 2

y = 4
