Answer:

157.44 feet

Step-by-step explanation:

Given that:

Lance is out for sightseeing in Rome.

Lance went to see the Colosseum.

Height of the outer wall of the Colosseum = 48 meters

Unit Conversion formula:

1 meter = 3.28 feet

To find:

Height of the outer wall of the Colosseum in feet.

Solution:

It is simple problem for the conversion of unit where we already know the value in one unit and the conversion formula as well.

We have to simply find how much 48 meters will be when converted in feet.

1 meter = 3.28 feet

48 meter = 48 [tex]\times[/tex] 3.28 = 157.44 feet

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:

slope intercept form is -2/3 for the first one

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:

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:

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: 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:

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:

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 :)

I was on the same problem and this was correct. Hope this helps!!

Step-by-step explanation:

[tex] \frac{6x - 2}{30} = \frac{5x + 13}{36} \\ 36(6x - 2) = 30(5x + 13) \\ 6(6x - 2) = 5(5x + 13) \\ 36x - 12 = 25x + 65 \\ (36 - 25)x = (65 + 12) \\ 11x = 77 \\ x = \frac{77}{11} \\ x = 7[/tex]

You can use the properties that similar triangles have sides scaled.

The value of x is 7.

Since it is given that PTS ~ PQR, thus, let the scaling is done by factor f. Then we have:

[tex]|PT| = f \times |PQ|\\ |TS| = f \times |QR|\\ |SP| = f \times |RP|[/tex]

Thus, we get the ratio of length of PT and length of TS as:

[tex]\dfrac{|PT|}{|TS|} = \dfrac{f \times |PQ|}{f \times |QR|} = \dfrac{|PQ|}{|QR|}[/tex]

Using the values specified in the given figure for above obtained equation, we get:

[tex]\dfrac{|PT|}{|TS|} = \dfrac{|PQ|}{|QR|}\\ \\ \dfrac{36}{30} = \dfrac{5x + 13}{6x-2}\\ \\ \text{Cross multiplying, the denominators},\\\\ 36(6x-2) = 30(5x+13)\\ 216x - 72 = 150x + 390\\ 216x - 150x = 390 + 72\\ 66x = 462\\\\ x = \dfrac{462}{66}\\\\ x = 7[/tex]

Thus, the obtained value of x is 7.

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:

See explanations below

Step-by-step explanation:

Given the system of equation

2x - 10 y = -30 ... 1

x - 5y = 20 ... 2

Step: From 2;

x = 20 + 5y ...3

Step 2: Substitute equation 3 into 1

2x - 10y = -30

2(5y+20) - 10y = -30

Open the bracket

10y + 40 - 10y = -30

10y - 10y + 40 = -30

0+40 = -30

40 = -30
