Answer:

4 have a great day (ik it's long but still helps)

Step-by-step explanation:

Here we will show you step-by-step with a detailed explanation of how to calculate 100 divided by 25 using long division.

Before you continue, note that in the problem 100 divided by 25, the numbers are defined as follows:

100 = dividend

25 = divisor

Step 1:

Start by setting it up with the divisor 25 on the left side and the dividend 100 on the right side like this:

2 5 ⟌ 1 0 0

Step 2:

The divisor (25) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

2 5 ⟌ 1 0 0

Step 3:

Multiply the divisor by the result in the previous step (25 x 0 = 0) and write that answer below the dividend.

2 5 ⟌ 1 0 0

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

2 5 ⟌ 1 0 0

- 0

Step 5:

Move down the 2nd digit of the dividend (0) like this:

2 5 ⟌ 1 0 0

- 0

1 0

Step 6:

The divisor (25) goes into the bottom number (10), 0 time(s). Therefore, put 0 on top:

0 0

2 5 ⟌ 1 0 0

- 0

1 0

Step 7:

Multiply the divisor by the result in the previous step (25 x 0 = 0) and write that answer at the bottom:

0 0

2 5 ⟌ 1 0 0

- 0

1 0

Step 8:

Subtract the result in the previous step from the number written above it. (10 - 0 = 10) and write the answer at the bottom.

0 0

2 5 ⟌ 1 0 0

- 0

1 0

- 0

1 0

Step 9:

Move down the last digit of the dividend (0) like this:

0 0

2 5 ⟌ 1 0 0

- 0

1 0

- 0

1 0 0

Step 10:

The divisor (25) goes into the bottom number (100), 4 time(s). Therefore put 4 on top:

0 0 4

2 5 ⟌ 1 0 0

- 0

1 0

- 0

1 0 0

Step 11:

Multiply the divisor by the result in the previous step (25 x 4 = 100) and write the answer at the bottom:

0 0 4

2 5 ⟌ 1 0 0

- 0

1 0

- 0

1 0 0

Step 12:

Subtract the result in the previous step from the number written above it. (100 - 100 = 0) and write the answer at the bottom.

0 0 4

2 5 ⟌ 1 0 0

- 0

1 0

- 0

1 0 0

- 1 0 0

You are done because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 100 divided by 25 calculated using Long Division is:

0 Remainder

Solve by substitution: 7x+4y=14 and x+2y=12 HURRY I'LL GIVE BRAINLIEST!!

antiseptic1488 [7]

Answer:

x = -2

y = 7

Step-by-step explanation:

x = 12 - 2y

7(12 - 2y) + 4y = 14

84 - 14y + 4y = 14

84 - 10y = 14

10y = 70

y = 7

x = 12 - 2 x 7

x = 12 - 14

x = -2

Rebecca and dan are biking in a national park for three days they rode 5 3/4 hours the first day and 6 4/5 hours the second day

likoan [24]

Answer:

Rebecca and Dan need to ride $7\frac{9}{20}\ hrs.$ on the third day in order to achieve goal of biking.

Step-by-step explanation:

Given:

Goal of Total number of hours of biking in park =20 hours.

Number of hours rode on first day = $5\frac34 \ hrs.$

So we will convert mixed fraction into Improper fraction.

Now we can say that;

To Convert mixed fraction into Improper fraction multiply the whole number part by the fraction's denominator and then add that to the numerator,then write the result on top of the denominator.

$5\frac34 \ hrs.$ can be Rewritten as $\frac{23}{4}\ hrs$

Number of hours rode on first day = $\frac{23}{4}\ hrs$

Also Given:

Number of hours rode on second day = $6\frac45 \ hrs$

$6\frac45 \ hrs$ can be Rewritten as $\frac{34}{5}\ hrs.$

Number of hours rode on second day = $\frac{34}{5}\ hrs.$

We need to find Number of hours she need to ride on third day in order to achieve the goal.

Solution:

Now we can say that;

Number of hours she need to ride on third day can be calculated by subtracting Number of hours rode on first day and Number of hours rode on second day from the Goal of Total number of hours of biking in park.

framing in equation form we get;

Number of hours she need to ride on third day = $20-\frac{23}{4}-\frac{34}{5}$

Now we will use LCM to make the denominators common we get;

Number of hours she need to ride on third day = $\frac{20\times20}{20}-\frac{23\times5}{4\times5}-\frac{34\times4}{5\times4}= \frac{400}{20}-\frac{115}{20}-\frac{136}{20}$

Now denominators are common so we will solve the numerator we get;

Number of hours she need to ride on third day = $\frac{400-115-136}{20}=\frac{149}{20}\ hrs \ \ Or \ \ 7\frac{9}{20}\ hrs.$

Hence Rebecca and Dan need to ride $7\frac{9}{20}\ hrs.$ on the third day in order to achieve goal of biking.

Porphyrin is a pigment in blood protoplasm and other body fluids that is significant in body energy and storage. Let x be a rand

SOVA2 [1]

Answer:

Question 1:

(a) P(x<60) = 0.9236

(b) P(x>16) = 0.9564

(c) P(16<x<60) = 0.88

(d) P (x>60) = 0.0764

Question 2:

(a) P(x<3) = 0.0668

(b) P(x>7) = 0.0062

(c) P(3<x<7) = 0.927

Step-by-step explanation:

Question 1:

x = no. of mg of porphyrin per deciliter of blood.

μ = 40

σ = 14

(a) We need to compute P(x<60). We need to find the z-score using the normal distribution formula:

z = (x - μ)/σ

P(x<60) = P((x - μ)/σ < (60 - 40)/14)

= P(z < 20/14)

= P(z<1.43)

Using the normal distribution probability table we can find the value of p at z=1.43.

P(z<1.43) = 0.9236

so, P(x<60) = 0.9236

(b) P(x>16) = P(z>(16-40)/14)

= P(z>-1.71)

= 1 - P(z<-1.71)

= 1 - 0.0436

P(x>16) = 0.9564

(c) P(16<x<60) = P((16-40)/14) < x < (60-40)/14)

= P(-1.71 < z < 1.43)

This probability can be calculated as: P(z<1.43) - P(z<-1.71)

P(16<x<60) = 0.9236 - 0.0436

P(16<x<60) = 0.88

(d) P(x>60) = 1 - P(x<60)

we have calculated P(x<60) in part (a) so,

P(x>60) = 1 - 0.9236

P (x>60) = 0.0764

Question 2:

μ = 4.5 mm

σ = 1.0 mm

In this question, we will again compute the z-scores and then find the probability from the normal distribution table.

(a) P(x<3) = P(z<(3-4.5)/1)

= P(z<-1.5)

P(x<3) = 0.0668

(b) P(x>7) = 1 - P(x<7)

= 1 - P(z<(7-4.5)/1)

= 1 - P(z<2.5)

= 1 - 0.9938

P(x>7) = 0.0062

(c) P(3<x<7) = P(x<7) - P(x<3)

we have computed both of these probabilities in parts (a) and (b) so,

P(3<x<7) = 0.9938 - 0.0668

P(3<x<7) = 0.927

Which graph best represents the equation x+2y=4

RUDIKE [14]

You didn’t show a picture of the graph, although the equation would be y=-1/2x+2
so every two x spaces forward you should go down one y space and the y should start at 2 when x = 0
