Answer:

[tex]3.75\ \text{m}[/tex]

Step-by-step explanation:

A escala da réplica é  [tex]1:80[/tex]. Isso significa que 1 metro da réplica da escala representa 80 metros do edifício real.

Portanto, 1 metro do edifício real representa [tex]\dfrac{1}{80}[/tex] metros da réplica.

Precisamos encontrar a altura da réplica

[tex]420\ \text{m}=420\times\dfrac{1}{80}=5.25\ \text{m}[/tex]

Assim, a réplica da escala terá uma altura 5.25 m.

Está colocado numa sala com 9 m de altura.

A distância entre o topo da réplica e o teto do corredor é [tex]9-5.25=3.75\ \text{m}[/tex].

Answer:

( 0, -4)

Step-by-step explanation:

The y-intercept in a linear function will always have 0 as the x-coordinate.

Answer: maybe c?

Step-by-step explanation:

from eqn. 1

3x + 2y = 23

2y = 23 - 3x

y = 23/2 - 3/2x

sub into eqn. 2

1/2x - 4 = 23/2 - 3/2x

1/2x + 3/2x = 23/2 + 4/1

2x = 23/2 + 8/2

2x = 31/2

x = 31/4

sub into eqn. 1

31/4 + 2y = 23

2y = 23 - 31/4

2y = 92/4 - 31/4

2y = 61/4

y = 61/8 or 7 5/8  

ummm i got something wrong but try c?

Answer:

C . 31/4,-1/8

Step-by-step explanation:

1. sub the given value of y

into 3x + 2 (1/2x -4) 23

2. slove for x = 31/4

3.sub the given value of x into 1/2x - 4 =y

4. solve the equation for y

5. y = -1/8

6. ordered pair to (x,y) = 31/4,1,8

I am trying to get 100 warns, pls help me

Answer:

The amount is $25.4

Step-by-step explanation:

There are 109 students to attend the science workshop.

Number of erasers needed is 109, but whole packages of erases can be bought which consist 12 erasers. The total packages of erasers needed would be 10.

The cost of 10 packages of erasers = $0.75 x 10

                                  = $7.5

The cost of 109 folders = 109 x $0.10

                                  = $10.9

Number of pencils needed is 109, but whole packages of pencils can be bought which consist 8 pencils. The total packages of pencils needed would be 14.

The cost of 14 packages of pencils = $0.50 x 14

                                  = $7.0

Total cost = $7.5 + $10.9 + $7.0

                = $25.4

The amount that would be spent by the school is $25.4

25.4

Step-by-step explanation:

Parallel lines have the same slope so they can therefore never touch. Just change the y-int. (Any number as long as it's not the same as the previous)

I.E.:

y = -3x - 12

Answer:

f(x)= x²+4x-21

a= 1 b=4 c=-21

from [tex]y=ax^2+bx+c[/tex] and [tex]y=x^2+4x-21[/tex] | Compare the coefficients.

Thus the answer is a = 1, b = 4 and c = -21

Answer:

The balance after 6 years is $1110.812026

Step-by-step explanation:

The rule of the compound interest is A = P[tex](1+\frac{r}{n})^{nr}[/tex], where

∵ Layla opened a savings account and deposited $700.00 as principal.

∴ P = 700

∵ The account earns 8% interest compounded annually

∴ r = 8% = 8 ÷ 100 = 0.08

∴ n = 1 ⇒ compounded annually

∵ The time is 6 years

∴ t = 6

→ Substitute these values in the rule above

∵ A = 700[tex](1+\frac{0.08}{1})^{1(6)}[/tex]

∴ A = 700[tex](1.08)^{6}[/tex]

∴ A = 1110.812026

∴ The balance after 6 years is $1110.812026

Equality Properties

Step-by-step explanation:

Step 1: Define

8x = 24

Step 2: Solve for x

We see that 8x is actually 8 times x. Therefore, we would need to use the Division Property of Equality to isolate x and get our answer.

Answer:

The average rate of change on the given interval is 9/70

Step-by-step explanation:

Here, we are to find the average rate of change of the function on the given interval

We proceed as follows;

on an interval [a,b] , we can find the average rate of change using the formula;

f(b) - f(a)/b-a

From the question;

a = 0

b = 3

f(0) = -3/5

f(3) = -3/14

Substituting the values, we have;

-3/14-(-3/5)/3-0

= 3/5-3/14/3

= (42-15)/70/3

= 27/70/3

= 27/70 * 1/3 = 9/70

Answer:

0.525%

Step-by-step explanation:

Since we are trying to find the probability of a sequence of events we simply need to multiply the probability of each of these events happening separately from one another. We are told that the probability that the light will be red is 65% that means that the probability that it will be green and that the driver will not need to stop is 35%. This probability remains the same every day of the week. Therefore we need to multiply this probability 5 times, one time for each weekday Monday through Friday, but first we need to turn this percentage into a decimal form by dividing it by 100...

35% / 100 = 0.35

0.35 * 0.35 * 0.35 * 0.35 * 0.35 = 0.00525 ...multiply by 100 to get percentage

0.00525 * 100 = 0.525%

Finally, we can see that the probability that she will not have to stop at the light all next week is 0.525%

3. No, I am not using my resources very efficiently. This is because when we need to make more hiking boots you have to make fewer running shoes.

4. I would recommend for them to focus on the hiking boots more because they use less material to make them.

hope this is correct c:

Yes, my resources are being used efficiently if I choose point D, as then I will be making equal amounts of product (1 to 1 ratio).

What is a statistics?

'Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.'

According to the given problem,

This is the most efficient point by far compared to the others, because the two axes are the closest together out of all of the 7 points.

I would recommend that the Shoe Hut focus on both of them, as they have a perfect 1 to 1 ratio.

However, if needed, it is possible to allocate all production power towards running shoe insoles at a 15 to 0 ratio compared to hiking shoe insoles at10 to 0.

Hence, we concluded that, It would be better for the shoe hut to focus on running shoe insoles because they are easier to produce and there is less production of cost.
