A swimming pool is 30 feet wide and 50 feet long. If it is surrounded by square tiles, each of which is 1 foot by 1 foot, how many tiles are there surrounding the pool?

Answer:

4

Step-by-step explanation:

4⁴¯³

=4^1

=4

So the answer is 4

Answer:

4^1

Step-by-step explanation:

since the base is 4 and the exponents are 4-3, 4-3 is 1 so therefore you're answer is 4^1

Answer:

your answer is -285,112

Step-by-step explanation: first you do this

[tex]\frac{y1}{y2} \frac{x1}{x2} \\[/tex]

the numders should go like this

[tex]\frac{-15}{-16} \frac{-7}{19}[/tex]

then you cross multiply

[tex]-15*(19)\\-7*(-16)[/tex]

the answers to the multiplication

[tex]-15*(19)= -285\\-7*(-16)=112[/tex]

the answer is

-285,112

Answer:

5 apples

Step-by-step explanation:

First, we must find the cost of one apple

12/20 = the cost of one apple

= $0.60

Then, we divide 3 by the price of one apple

3/0.6 = amount of apple we can buy

= 5

Answer:

0.33696

Step-by-step explanation:

Given that:

Probability of showing up head (p) = 0.6

Number of flips = number of trials = 5

Probability of getting more than 3 heads

P(x = x) = nCx * p^x * (1 - p)^(n-x)

P(x> 3) = p(4) + p(5)

P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592

P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776

Hence,

0.2592 + 0.07776

= 0.33696

Following are the calculation to the probability:  

The probability to see the head [tex](p)= 60\%= 0.60[/tex]

Amount of flips = amount of tries = 5

Chances of getting and over three heads:

            [tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]

Hence,

                       [tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]

Therefore, the final answer is "0.34"

Answer:

13 + 1/3 and 26+2/3

Step-by-step explanation:

so one is twices a large as the first. so 40/3 = 13 + 1/3 so thats one of your awnsers the larger one is 2 times larger so13 +1/3 * 2 is 26+2/3 hope this helps! :D

Answer:

First Number is 13

Second Number is 27

Step-by-step explanation:

let x = first number

let 2x + 1 = second number

x + (2x + 1) = 40

3x + 1 = 40

    - 1      -1

3x = 39

/3      /3

x = 13

13 x 2 = 26 + 1 = 27

Answer:

y = -x - 4

Step-by-step explanation:

y = mx + b

Slope (m) = -1 (left 1, up 1)

Y-intercept (b) = -4

Answer:

∠1 = 130

∠3 = 130

∠2 = 50

Step-by-step explanation:

180 - 50 = 130

∠1 = ∠3 = 130 degrees

∠2 = 50 degrees

Given:

Answer:

18.5

Step-by-step explanation:

It says

IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.

so HF is 10 cm .. half of that is 5 cm

GH is 13 cm.. Half of that is 6.5 cm

now we have IJ = 7 cm given

add all those.. you get 18.5 cm

Answer:

18.5

Step-by-step explanation:

35.

Segment IJ is a midsegment of triangle FGH, so

2HI = 2FI = FH

2HJ = 2JG = GH

FG = 2IJ

Perimeter of triangle IJH = IJ + JH + HI

IJ + JH + HI = 7 + 6.5 + 5 = 18.5

Answer:

y = 2/5x + 2

Step-by-step explanation:

y = mx + b

Slope (m) = 2/5

Y-intercept (b) = 2

X-intercept (x) = -5

(-5, 0) (0, 2)

2-0 =    2

0 + 5 = 5

die Antwort -2 -4 (6p-5)

Step-by-step explanation:

Answer:

14°

Step-by-step explanation:

We know that ∠PQS is a right angle.

We also know that ∠PQR is 76°.

So, to find ∠RQS, we can do 90°-76° = 14°

x° = 14°

Answer:

[tex] \huge{ \boxed{ \bold{ \tt{x = 14 \degree}}}}[/tex]

Step-by-step explanation:

♨ First , let's know about complementary angles :

✎ Now, set up an equation and solve for x :

Move 76° to R.H.S ( Right Hand Side ) and change it's sign

➺ [tex] \sf{x \degree = 90 \degree - 76 \degree}[/tex]

➺ [tex] \boxed{ \bold{ \sf{x \degree = 14 \degree}}}[/tex]

And we're done !

Step-by-step explanation:

Answer:

4/5

Step-by-step explanation:

75% = 75/100 = 0.75 = 3/4

4/5 = 80/100 = 80% = 0.80

75 = 75% = 3/4 = 75/100

75%

80% - this is the biggest

75%

HOPE THIS HELPS

PLZZ MARK BRAINLIEST

Answer: 4/5

Step-by-step explanation:

75% = 75/100 same as 0.75

4/5 = 0.80

0.75 already in decimal

Therefore 0.80 is the greatest

Answer:

85.40

Step-by-step explanation: This is because if you do $70*22%, this gives $15.4. Now add this to $70 to get 80.40!  So, the total is 80.40.

Answer:

[tex]y = -5x - 3[/tex]

Step-by-step explanation:

The data in the question are not properly presented.

See attachment for graph

To determine the graph, first we need to calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Where x and y are corresponding values:

When x = -1; y = 2;

This implies [tex](x_1,y_1) = (-1,2)[/tex]

When x = 0; y = -3

This implies [tex](x_2,y_2) = (0,-3)[/tex]

So:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-3 - 2}{0 - (-1)}[/tex]

[tex]m = \frac{-3 - 2}{0 +1}[/tex]

[tex]m = \frac{-5}{1}[/tex]

[tex]m = -5[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x-x_1)[/tex]

Where:

[tex]m = -5[/tex]

[tex](x_1,y_1) = (-1,2)[/tex]

[tex]y - 2 = -5(x -(-1))[/tex]

[tex]y - 2 = -5(x +1)[/tex]

[tex]y - 2 = -5x -5[/tex]

Make y the subject

[tex]y = -5x - 5 +2[/tex]

[tex]y = -5x - 3[/tex]

Please note that the graph I attached may/may not be the right graph to your question.

However, if you follow the steps I used in answering this question, you'll get the right answer to your question.

Hey there!

3x - 5x + 5 = 20

• First COMBINE your LIKE TERMS

(3x - 5x) + (5) = 20

3x - 5x = -2x

• NEW EQUATION:

-2x + 5 = 20

• SUBTRACT by 5 on BOTH SIDES

Like: -2x + 5 - 5 = 20 - 5

Cancel out: 5 - 5 because that gives you a 0

Keep; 20 - 5 because it helps us solve for your x

**20 - 5 = 15**

• NEW EQUATION:

-2x = 15

• DIVIDE by -2 on BOTH SIDES

2x/-2 = 15/-2

Cancel out: -2x/-2 because that gives you 1

Keep: 15/-2 because it helps us solve for x (it also gives the value of “x”)

**AFTER SOLVING ABOVE WE FOUND OUR ANSWER**

Answer: x = -15/2 ✅

Good luck on your assignment and enjoy your day!

Answer:

-0.057

Step-by-step explanation:

Because it is in the farthest decimal point from the rest, and trust me.

Answer:

-0.057

Step-by-step explanation:

(possibly wrong)

because it's farther away from the positives or 0

Answer:

(a) TRUE

(b) TRUE

(c)  FALSE

(d) TRUE

Step-by-step explanation:

" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".

(a) TRUE

Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0

(b) TRUE

this could be seen clearly from the number line.

(c) FALSE

this statement is false since we can take example of zero.

the opposite of zero is 0 but 0×0≠1.

(d) TRUE

since 0-0=0.Step-by-step explanation:

Answer:

The number 11 is not a solution for the given equation.

Step-by-step explanation:

We are given an equation with one variable. We can use simplifying processes to solve the equation.

[tex]3(x+6)=4x \ \ \text{Distribute the 3 through.}\\3x + 18 = 4x\ \ \ \text{Flip the equation.}\\4x = 3x + 18 \ \ \ \text{Subtract 3x from both sides.}\\\small\boxed{\bold{x = 18}}[/tex]

We can also substitute 11 for x and solve to see if the left side and right side of the equation equals itself.

[tex]3(11 + 6) = 4(11)\\33 + 18 = 44\\\small\boxed{\bold{51 \neq 44}}[/tex]

Therefore, 11 is not a solution for the given equation.

Answer:

[tex] \displaystyle \rm \longmapsto \:3(x + 6) = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:3x + 18 = 4x[/tex]

[tex] \displaystyle \rm \longmapsto \:4x = 3x + 18[/tex]

[tex] \displaystyle \rm \longmapsto \:4x - 3x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:x = 18[/tex]

[tex] \displaystyle \rm \longmapsto \:3(11 + 6) = 4(11)[/tex]

[tex] \displaystyle \rm \longmapsto \:33 + 18 = 44[/tex]

[tex] \displaystyle \rm \longmapsto \:51 = 44[/tex]
