Answer: 42.16l

Step-by-step explanation:

First, we should note that August has 31 days. Since Jan's house has four leaking taps and an average of 34 cL of water leaks from each tap every day. The four taps will leak (34 × 4) = 136 cL everyday.

The amount of litres of water that is lost from these four taps in August would be:

= 136cL × 31

= 4216 cL

= 42.16L

We should note that 100cL = 1L

Answer:

y=-3x-3

Step-by-step explanation:

Recall that slope intercept form is written exactly the way it's described: it gives you the slope of the line, then its y-intercept.

So first we can look at the graph, and see that for every 1 unit traveled to the right, the line travels 3 units down.  Therefore our slope is -3.

Now we look for the y-intercept - we see the line intersects the y-axis at -3.

So our equation is:

y = -3x - 3

Answer:

500 miles

Step-by-step explanation:

81-11 is 70. 70 divided by .14 is 500 so that's 500 miles she can bike.

Answer:

500 miles

Step-by-step explanation:

To find out how many miles Candice can hike at max, use the equation 11 + 0.14x = 81.

11 + 0.14x = 81

Subtract 11 from both sides. This undoes the +11.

0.14x = 81 - 11

Subtract 11 from 81 to get 70.

0.14x = 70

Divide both sides by 0.14. This undoes the multiplication by 0.14.

x = 70/0.14

I recommend converting 0.14 into a fraction. That would be 7/50.

x = 70/(7/50)

Find the reciprocal of 7/50 (50/7). Switch the sign from division to multiplication.

x = (70 * 50)/7

Multiply 70 by 50 to get 3500.

x = 3500/7

Divide 3500 by 7 to get 500.

x = 500

At max, Candice can hike 500 miles.

Answer:

x = 6

Step-by-step explanation:

angles 1 and 2 are equal because the entire angle is bisected

so, 5x - 2 = 4x + 4

x - 2 = 4

x = 6

If you substitute 6 into each expression, they should be equal:

4(6) + 4 = 5(6) - 2

24 + 4 = 30 - 2

28 = 28

Answer:

2 2/21

Step-by-step explanation:

11/2 ÷ 2 5/8

= 11/2 ÷ 21/8

= 11/2 × 8/21

= 88/42

= 44/21

= 2 2/21

Hence 11/2÷2 5/8 is 2 2/21

Answer:

8.) 9.15 x 10^18

Step-by-step explanation:

to get scientific notation, you move the decimal place until all numbers except one are past the decimal. If you move it to the left, the exponent is postitive. If you move it to the right, it's negative. So, 9,150,000,000,000,000,000 expressed in scientific notation is 9.15 x 10^18 because you moved the decimal 18 spaces to the left.

The number 9,150,000,000,000,000,000 expressed in scientific notation will be 9.15 × 10¹⁸ or 9.15E18. Then the correct options are A and B.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The number is given below.

⇒ 9,150,000,000,000,000,000

The number represented in the scientific notation will be given as,

⇒ 9,150,000,000,000,000,000

⇒ 9.15 × 10¹⁸

⇒ 9.15E18

The number 9,150,000,000,000,000,000 expressed in scientific notation will be 9.15 × 10¹⁸ or 9.15E18. Then the correct options are A and B.

Answer:

it's answer is 89 mm

Step-by-step explanation:

Perpendicular (p) = 80 mm

base(b) = 39 mm

hypotenuse (h) = ?

By using Pythagoras theorem,

h = √( p² + b²)

= √ ( 80² + 39²)

= √7921

=√(89)²

= 89 mm

Answer:

89 mm

Step-by-step explanation:

Use the pythagorean therom to solve for the hypotenuse which is (c).

Ex: a^2+b^3=c^2

Subsitute

80^2+39^2=c^2

6400+1521=c^2

6400+1521=c^2

Add

6400+1521=7921

Now you have the following equation...

7921=c^2

Sqaure both sides of the equation

sqrt7921=sqrtc^2

89=c

So C=89 mm there you go :)

MARK ME BRAINLISET THANKS!!!

Answer:

x = 3

y = 21

(3,21) and if u want slope it will be 7 :D

Step-by-step explanation:

y = 10x - 9

y = x + 18

1. Substitute for the y

10x - 9 = x + 18

2. Add 9 onto both sides

10x - 9 + 9 = x + 18 + 9

10x = x + 27

3. Subtract x on both sides

10x -x = x - x+ 27

9x = 27

4. Divide by 9 on both sides

9x/9= 27/9

x = 3

__________________________________________________________

Now that you have x, substitute that into one of the equations

y = x + 18

y = 3 + 18

y = 21

or  

y = 10x - 9

y = 10(3) - 9

y = 30 - 9

y = 21

there both the same

__________________________________________________________

x = 3

y = 21

Hope this helped!

Answer:

x +18 = 10x -9 (since they both = y, set them equal to each other. )

-9x +18 = -9 (subtract 10x from both sides, then subtract 18 from both sides)

-9x = -27 (divide both sides by -9 to isolate x)

x= 3 (take this and plug it into one of the equations to solve for y)

y = x +18 (i choose this one)

y = 3+18 (add)

y = 21 (take this and x and make a point and that's your answer)

Answer:

u=8

3u+5u=64

8u=64

u=8

finish

Hey there!

FIRST: you have to SIMPLIFY BOTH SIDES of your given EQUATION (there’s approximately 3 ways but we will use 2)

• 3u = 64 – 5u

• 3u = –5u + 64

SECOND: ADD by 5u on BOTH SIDES

• 3u + 5u = –5u + 64 + 5u

• CANCEL: –5u + 5u because that gives you 0

• KEEP: 3u + 5u because it can help us solve for you u-value

“3u + 5u = 8u”

New equation: 8u = 64

THIRD: DIVIDE by 8 on BOTH SIDES

• 8u/8 = 64/8

• CANCEL out: 8u/8 because that gives you 1

• KEEP: 64/8 because that gives you your u-value

“64/8 = u”

“64/8 = 8”

• Therefore your ANSWER: u = 8 ☑️
