Step-by-step explanation:same but in the past

According to the Question

Two buses started 2400 miles apart

They pass each other and they must have together to cover = 2400 miles

Now

Using Formula :-

Distance = Speed × Time

First bus ⇒ 5 × b = 5b

Second bus ⇒ 5(b + 60)

Now put in a Equation we get :-

5b + 5(b + 60) = 2400

5b + 5b + 300 = 2400

10b + 300 = 2400

10b = 2400 - 300

10b = 2100

b = 2100 / 10

b = 210

Hence :-

One bus speed is 210 miles

Another bus speed ⇒ 210 + 60 = 270 miles

Answer:

A: The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.

B: he correlation coefficient is a statistical calculation that is used to examine the relationship between two sets of data. The value of the correlation coefficient tells us about the strength and the nature of the relationship. Correlation coefficient values can range between +1.00 to -1.00.

Answer:

After 20 days, the two runners will have run the same number of miles

Step-by-step explanation:

The problem can be solved by using equations. However, we'll approach the solution by using pure reasoning and logic, besides calculations.

The first runner has already run 15 miles this month and plans to run 2 1/2=2.5 miles per day for the rest of the month.

The other runner has not yet run and plans to run 3 1/4 = 3.25 miles per day for the rest of the month. Since his running rate is greater than the other runner, they will both eventually have the same number of miles.

The difference in their running rates is 3.25 - 2.5 = 0.75 miles per day. Since the current difference between them is 15 miles, the second runner needs to run for 15 / 0.75 = 20 days.

After 20 days, the two runners will have run the same number of miles

The volume of large cube = 8 × Volume of small cube

Answer:

$32.65 is the answer.

Step-by-step explanation:

First, we must calculate 7.25% of 30.45.

30.45 x 0.0725 = $2.20

Now, we must add this to the original price

$30.45 + $2.20 = $32.65

Therefore, $32.65 is the total cost of his purchase.

Hope this helps! :)

Answer:

Step-by-step explanation:

before tax = $30.45

tax sales = 7.25%

total cost = $30.45 x 1.0725

               = $32.66

Answer:

Step-by-step explanation:

a). 3 ...... 8

3 × 8 = 24

3 + 8 = 11

b). n + 1.5 = 6.5 ⇒ n = 5 (across from OR to the left from 1.5)

5 × 1.5 = 7.5 (under the X sign)

Step by step:

A:

2x+8=-3.5x+19

2x+3.5x=19-8

5.5x=11

x=2

B:

Answer:

yes

Step-by-step explanation:

This is correct.

Since every operation in this is multiplication, you can remove the parentheses. This is the associative property of multiplication. Now you can group the exponents and the normal factors together.

[tex](1.5*2.0)*(10^{0} *10^{-5})[/tex]

[tex]3.0*10^{-5}[/tex]

So the answer you put is correct. But, if your test is online and has a dumb grading system (like edulastic) I suggest you put 3.0 instead of 3.

Answer:

No she should add extra lengths

Step-by-step explanation:

The difference between scaled copy  and jada drawing is that it is in the ratio

8:4

2:1

that is the scaled copy is twice as large as the jada drawing itself.

So every dimension is doubled or made twice as large as the initial measurement. Andre should not add 4 units to all sides instead the drawing is made twice as large . It will serve the same purpose of enlarging the drawing while maintaining its shape. If extra mesurements are added the drawing will be changed.

x to y can be expressed as a fraction this way: x/y.

Let x = 12

Let y = 18

12/18

We can now reduce to lowest terms.

Dividing 12 and 18 by 6, we get 2/3 as the final answer.

The simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.

To express the ratio 12 to 18 as a fraction in simplest form, we can divide both numbers by their greatest common divisor (GCD). The GCD of 12 and 18 is 6. By dividing both numbers by 6, we simplify the fraction to its simplest form:

12 ÷ 6 = 2

18 ÷ 6 = 3

Thus, the simplified fraction is 2/3. This means that the ratio of 12 to 18 can be expressed as 2/3. It indicates that for every 2 units of the first quantity (12), there are 3 units of the second quantity (18). Simplifying the fraction ensures that there are no common factors other than 1 between the numerator and the denominator, making it the simplest representation of the ratio.

Answer:

option b ......................

The equation that can be used to solve  log₄(x + 4) + log₄(x - 2) = 2 is

x² + 2x - 8 = 0.

The logarithm is the opposite of the exponential function.

This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.

Given, log₄(x + 4) + log₄(x - 2) = 2.

We know logₐx + logₐy = logₐxy.

log₄(x + 4)(x - 2) = 2.

log₄(x² - 2x + 4x - 8) = 2.

log₄(x² + 2x - 8) = 2.
