Han's house is 450 meters from school. Lin’s house is 135 meters closer to school. How far is Lin’s house from school (represented by the letter z)?

A: z+135=450
B: z=450−135
C: z=450−135
D: z=450−135

Step-by-step explanation:

15.00_____100percent

18.60_____124 percent.

it increased witf 24 percent

Answer:

0.2% increase

First, you find the change between $15.50 and $18.60, which is 3.10. Then you do 3.10 divided by the original, which is 15.50. You should get 0.2.

\(\frac{37}{60}\) or 0.62 of a mile that he will need to complete to reach his target.

Step-by-step explanation:

\(2 \frac{3}{4} + 3 \frac{1}{2} + 5 \frac{1}{3} + 2 \frac{4}{5} = \frac{863}{60} \\18-\frac{863}{60} = \frac{37}{60}/ 0.62\)

Answer:

415.27in^2

Step-by-step explanation:

area of a circle is

a= pi(r)^2

the radius is half of the diameter so you would do 23/2 = 11.5 for the radius

a= 3.14 (11.5)^2

= 3.14 x 132.25

= 415.27 inches^2

Answer: A 1/5

Step-by-step explanation:

Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.

What is probability ?

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

Number of blue marbles = 5,

Number of red marbles = 8,

Number of white marbles = 4,

And number of purple marbles = 3.

Total number of marbles = 5 + 8 + 4 + 3 = 20

Probability of getting blue marble = number of blue marbles/total number of marbles

=5/20=1/4

Apply same formula,

Probability of getting red marble= 8/20 = 2/5

Probability of getting white marble = 4/20 = 1/5

Probability of getting purple marble = 3/20

A 1/5

The equation represents: A relation and a function

Step-by-step explanation:

A function is said to be a relation; however, the relation does not have to function. For a relation to result in a function, then every input gives an important output. Thus; the given information x² + y - 15 = 0 can be re-written as:

y = - x² + 15

Similarly, the equation typically illustrates a relation as well. Consequently, suppose we replace any x-value for x, then the one possible output will be for y. Hence, that is also a function.

Answer:

  (a)  88 m

  (b)  74 cm

Step-by-step explanation:

You want the length of a garden with a perimeter of 330 m and a width of 77 m, and you want the width of a window with an area of 6734 cm² and a length of 91 cm.

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Filling in the given values, we can find the unknown.

  330 = 2(L +77)

  165 = L +77 . . . . . . . divide by 2

  165 -77 = 88 = L

The length of the garden is 88 meters.

The area of a rectangle is given by the formula ...

  A = LW

Filling in the given values, we can find the unknown.

  6734 = 91W

  6734/91 = 74 = W

The width of the window is 74 cm.

<95141404393>

Answer:

8.

60 * 2 + 30 = 150km

225 - 150 = 75km

50km/h  and  75km, so 1.30h

1.30 + 2.30 + 0.10 = 4.10h

Im not very good at english so I dont know how to explain...

9.

1.30 - 47 = At 12.43

Answer:

9π

Step-by-step explanation:

What we need  to do here is convert this equation into a standard circle equation;

x^2+y^2 + 3 = -4y + 6x-1,

x^2+y^2+4y-6x+1 = 0,

x^2-6x+(-3)^2 + y^2+4y+(2)^2  = 3^2

(x-3)^2 + (y+2)^2 = 3^2,

so we have a circle with a radius of 3, and hence the area of our region is π(3)^2 = 9π. correct!

Answer:17

Step-by-step explanation:

1) 30 -13=17

Answer:

B)  m + 7

Step-by-step explanation:

x + y + z = (m+9)/2 + (2m+15)/2 + (3m+18)/2 = (6m + 42)/2 = 3m + 21

Average of x, y, and z = (x + y + z)/3 = (3m + 21)/3 = m + 7

Answer:

m + 7

Step-by-step explanation:

\(x = \frac{m + 9}{2}\\ \\y = \frac{2m + 15}{2}\\\\z = \frac{3m + 18}{2}\\\\To\;\;find\;\;\\\frac{x+y+z}{3} \\\\= \frac{1}{3} *[\frac{m + 9}{2}+\frac{2m + 15}{2}+\frac{3m + 18}{2}]\\\\= \frac{6m + 42}{6}\\ \\= m + 7\)

Sorry to say this but the answer isn't C it is D. It is 1:5 I did the test and past sorry i came so late

but i hope this helps ^.^

Hey there!

2 × 3^2 × 5

= 2 × 3 × 3 × 5

= 2 × 9 × 5

= 18 × 5

= 18 + 18 + 18 + 18 + 18

= 36 + 36 + 18

= 72 + 18

= 90

90: 2, 3, 3, & 5

Prime Facrorization of 90:

2 × 3 × 3 × 5

Thus, your answer is: 90

Good luck on your assignment & enjoy your day!

The equation of line passes through the points (0, -5) and (5, -2) will be;

⇒ y = 3x/5 - 5

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Two points on the line are (0, -5) and (5, -2).

Now,

Since, The equation of line passes through the points (0, -5) and (5, -2).

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (- 2 - (-5)) / (5 - 0)

m = 3 / 5

m = 3/5

Thus, The equation of line with slope 3/5 is,

⇒ y - (-5)= 3/5 (x - 0)

⇒ y + 5 = 3x/5

⇒ y = 3x/5 - 5

Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;

⇒ y = 3x/5 - 5
