Answer:

3 days

Step-by-step explanation:

Kali runs 10 laps around a track each day, and each lap is 400 meters. So, the first step would be:

10 • 400 = 4,000

That means Kali runs 4,000 meters each day.

Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.

The final step is to divide. 12/4 = 3

So, it would take 3 days for him to run a total of 12 kilometers.

Answer:

Kali will run 3 days

76

Hope this helps!

Answer:

76

Step-by-step explanation:

It is easier to do x square first which gives you 16

Then do 16 times 4 which is 64

Then do x times -3 which is -12

Then do the sum 64-(-12)

which gives you the answer of 76

Answer:

12 m

Step-by-step explanation:

If 1 m = 3.3 feet, then,

1 feet = 1/3.3 m

So,

39.6 feet

= 39.6/3.3

Multiplying by 10....

= 396/33

= 12 m

Answer:

y = 2x

the formula for linear equations are y = mx+c,

where m is the gradient,

and c is the y-intercept

to find m (the gradient):

1. pick to points on the graph (eg. -2,-4 and 2,4)

2 substitute the values into the formula for gradient y2-y1/x2-x1.

m = y2-y1/x1-x2

= -4 -4/-2-2

= -8/-4

= 2

to find c (y-intercept):

- the y-intercept is where the graph cuts the y axis

- in this graph, the y-intercept is 0

hence,

c = 0

substitute m = 2 and c = 0 to y = mx+c,

y = 2x + 0

y = 2x

hence, the equation that best represents the relationship shown in the graph is y = 2x.

Answer:

0.8x - y = -1.8, x-int = 2.25, y-int = -1.8

Step-by-step explanation:

(-4, -5) and (1, -1)

slope = [(-5) - (-1)] / [(-4) - 1] = -4 / -5 = 4/5 = 0.8

Let y = 0.8 x + b

Sub (-4, -5) into it

-5 = 0.8 * (-4) + b = -3.2 + b

b = -5 + 3.2 = -1.8

The equation is y = 0.8x - 1.8

standard form: 0.8x - y = -1.8

let y = 0, 0.8x - 1.8 = 0

x = 1.8/0.8 = 2.25   (x-intercept)

let x = 0, y = -1.8    (y-intercept)

Let's write the equation in standard from

[tex]y = mx + b[/tex]

Where,

[tex] \boxed{ \sf \: m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}}}[/tex]

[tex] \tt \: m = \frac{13 - 12}{1 - 0} [/tex]

[tex] \tt \: m = \frac{1}{1} [/tex]

[tex] \tt \: m = 1[/tex]

[tex] \sf \: y = 1x + 12[/tex]

Solution:

Step-1: Create a coordinate plane.

Step-2: Plot the points on the graph.

Step-3: Choose any two points on the graph.

Step-4: Find the slope of the line by using y₂ - y₁/x₂ - x₁.

Step-5: Find the y-intercept.

Step-6: Revise the equation created.

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

[tex]A=\pi r^{2}[/tex]

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

[tex]A=\pi (21)^2\\A=441\pi \\A=1385.44236...[/tex]

So, to the nearest whole number, the area of the circle is 1385 square mm.

Answer:

[tex]602.8cm^{3}[/tex]

Step-by-step explanation:

Volume of cylinder = π [tex]r^{2}h[/tex]

Here, [tex]r=4cm\\ h=12cm[/tex]

Volume = π × [tex]4^{2}[/tex] × [tex]12[/tex]

[tex]=602.8cm^{3}[/tex] (converted to 1 decimal place)

Given :

To Find :-

Solution :-

From the given figure we can see that the prism is made up of

And the base and height of each triangle is ,

And the dimensions of each rectangle is ,

Therefore , the Total surface area is ,

→ TSA = 2( area of each ∆) +3(area of each rectangle)

→ TSA = 2 ( 1/2 * 7 * 5)in.² + 3(13*6.1) in.²

→ TSA = 2 * 35/2 in.² + 3* 79.3 in.²

→ TSA = 35 in.² + 237.9 in.²

→ TSA = 272.9 ≈ 273 in.²

Hence the TSA of prism is 273 in.² .

Applying the expression for speed, we found that the time taken for the bucket to hit the bottom of the well is 15 seconds

Given Data

Speed = 2 meters per second

Distance = 30 meters

Time = ??

We know that the expression for the relationship between speed, distance and time is given as

Speed = Distance/Time

substituting we have

2 = 30/t

cross  multiplying

2t = 30

divide both sides by 2

t = 30/2

t = 15 seconds

Answer 15 seconds

Answer:

The answer is below, y = 2x - 2

Step-by-step explanation:

2x - y > 2

-2x       -2x

-y > 2 - 2x

/-1     / -1

y < -2 + 2x, also written as y < 2x - 2

This is where we got our answer: y = 2x - 2
