Find the missing number:

Mathematics
1 answer:
Makovka662 [10]2 years ago
7 0

Answer:

20%

Step-by-step explanation:

If you see they say that the number decreased is 10% each and they say it two times. we could see that the missing number is as big as the length of two 10% together, so if you add them two you get 20%.

See attachment for complete question

Required

Complete the double number line

The given double number lines represent a linear function between cups of flour (c) and number of batched (n)

Pick any two pairs:

(c_1,n_1) = (\frac{3}{4},1)

(c_2,n_2) = (3\frac{3}{4},5)

First, calculate the rate of change (i.e. slope, m):

m = \frac{n_2 - n_1}{c_2 - c_1}

m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}

m = \frac{4}{3}

So: the equation is:

n = m(c - c_1) + n_1

This gives:

n = \frac{4}{3}(c - \frac{3}{4}) + 1

n = \frac{4}{3}c - 1 + 1

n = \frac{4}{3}c

So, the above represents the relationship between n and c.

<u>To complete the table</u>

When n = 2

Substitute n = 2 in: n = \frac{4}{3}c

2 = \frac{4}{3}c

Make c the subject

c = \frac{3*2}{4}

c = \frac{3}{2}

When n = 3

Substitute n = 3 in: n = \frac{4}{3}c

3 = \frac{4}{3} * c

Make c the subject

c = \frac{3*3}{4}

c = \frac{9}{4}

When c=3

Substitute c=3 in: n = \frac{4}{3}c

n = \frac{4}{3} * 3

n = 4

So, the complete table is:

c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5

What is the equation for the line in slope-intercept form?
iris [78.8K]

Answer:

y = mx+b

Step-by-step explanation:

This is the equation for finding the slope-intercept form. Just plug in the numbers and you'll get your answer.

I know this doesn't give you the exact answer, but you have to figure things out on your own. It's good to get a little help, but not the direct answer.

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s a
Nimfa-mama [501]

Answer:

Step-by-step explanation:

When Riko left his house, Yuto was 5.25 miles along the path.

Average speed of Riko = 0.35 miles per minute

Average speed of Yuto = 0.25 miles per minute

First we will calculate the time in which Riko will catch Yuto on the track.

Relative velocity of Riko as compared to Yuto will be = velocity of Riko - velocity of Yuto

= 0.35 - 0.25

= 0.10 miles per minute

Now we this relative velocity tells that Riko is moving and Yuto is in static position.

By the formula,

Average speed = \frac{Distance}{Time}

0.10 = \frac{5.25}{t}

t = \frac{5.25}{0.1}

t = 52.5 minutes

Now we know that Rico will catch Yuto in 52.5 minutes. Before this time he will be behind Yuto.

So duration of time in which Rico is behind Yuto will be 0 ≤ t ≤ 52.5

Here time can not be less than zero because time can not be with negative notation. It will always start from 0.
