Answer:

1:400

Step-by-step explanation:

1 m = 100 cm

72 m = 7200 cm

Ratio of model size to real size

18 cm : 7200 cm

Divide both numbers by 18.

1 cm : 400 cm

Divide both sides by cm.

1:400

Answer:

im pretty sure its 12

Step-by-step explanation:

you have to do 1012 divided by 78 and you get 12.97, but since he wants them to all be 78 feet long, it cant be 13.

If 2/a, a/8, and 63% = 63/100 are in numerical order, then

2/a < a/8 < 63/100

Multiply each "side" of the inequality by 8a :

16 < a² < 126a/25

a has to be a whole number, and since 4² = 16, we must have at least a ≥ 5.

Divide through by a :

16/a < a < 126/25 = 5 + 1/25

Then at most, a ≤ 5.

So, both a ≥ 5 and a ≤ 5, which means a = 5.

Just to check that the list is in order, we have

2/a = 2/5 = 0.4

a/8 = 5/8 = 0.625

and 0.4 < 0.625 < 0.63.

Answer:

-10.47 is the answer

Step-by-step explanation:

Calculator

Answer:

Given equation:  y = x² + 2x - 3

If you wish to find the values of y when x = -2 and x = -5:

When x = -2:

⇒ y = (-2)² + 2(-2) - 3

⇒ y = 4 - 4 - 3

⇒ y = -3

When x = -5:

⇒ y = (-5)² + 2(-5) - 3

⇒ y = 25 - 10 - 3

⇒ y = 12

If you wish to find the value of y when x = -2-5:

When x = -2-5 ⇒ x = -7

⇒ y = (-7)² + 2(-7) - 3

⇒ y = 49 - 14 - 3

⇒ y = 32

Answer:

y = 32

Step-by-step explanation:

Given :-

y = x² + 2x - 3

x = -2-5 = -7

To Find :-

y

Inputting the value of x :

y = (-7)² + 2(-7) - 3

y = 49 - 17

Solution :-

y = 32

Using the normal distribution, we got that expression for the z-score of her test score is

[tex]z= \frac{72-29}{7} \\\\z=-7/7\\\\z=-1[/tex]

it's a type of probability distribution which is  symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.

Given that mean =[tex]\mu=79[/tex]

and standard deviation =[tex]\sigma = 7[/tex]

X=73

we know that formula of z-score is

[tex]z=\frac{X-\mu}{\sigma}[/tex]

Hence Z-score can be calculated as

Answer:

x is equal to 5

Step-by-step explanation:

78 = 12x + 18

12x + 18 = 78

12x = 78 - 18

12x = 60

x = 60/12

x = 5

btw i made 78 equal to 12x + 18 because it is parallel. they both equal the same (i think its called parallel. idrk)

X is equal to 5

78=12x+18

12x=78-18

12x=60

X=60/12

Answer:

$133.20

Step-by-step explanation:

Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.

1. Multiply 7.20 by 18 to get 129.60

2. Multiply 0.50 by 7.20 to get 3.60.

3. Add 129.60 and 3.60 together to get the answer, 133.20.

Any point on the outside edge of a circle from the center of a circle would be the radius, which would be the same distance all the way around. The outer edge of the larger circle goes through the dot labeled B, which is the center of the smaller circle, therefore any distance from B to the outer edge would be the same.

The length of segment BD is the same as the length of segment AB because any distance from B to the outer edge would be the same.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

Any point on the outside edge of a circle from the center of a circle will be the radius, which would be the same distance all the way around.

The outer edge of the larger circle goes through the dot labeled B, which means the center of the smaller circle.

answer : f(t) = 4000 + 170t

f(t) = principal + (principal multiplied by interest rate) multiplied by time

f(t) = 4000 + (4000*.0425)t

f(t) = 4000 + 170t

t = number of years

======================================================

Explanation:

We use the simple interest formula which is

i = P*r*t

where in this case,

We then get the following

i = P*r*t

i = 4000*0.0425*t

i = 170t

Showing that the amount of simple interest earned is 170 times that of the number of years.

For instance, if Carmen waits t = 10 years, then she earns i = 170*t = 170*10 = 1700 dollars in interest alone.

The expression 170t is the interest only. Add on the original amount deposited to find the total account balance after t years. Therefore, we arrive at 170t+4000 to get the linear function f(t) = 170t+4000

The 170 acts like the slope while the 4000 is the y intercept.

Answer:

6 hours

Step-by-step explanation:

Let's highlight/bold some important terms.

A car drives 60 mph. Write and solve an eqaution to find the number of hours it takes the car to travel 360 miles.

So we know Speed multiplied by Time is equal to distance, or commonly known as;

S · T = D

So since we know this, we can substitute the values for the variables.

We know the mph is 60. And that's our speed.

The equation is now 60 · T = D

We know that the total distance the car needs to cover is 360.

The equation is now 60 · T = 360

Now we need to find the time it took.

We divide 360/60 to find out the total number of hours it took, and we get 6.

So the answer is that it took 6 hours to travel 360 miles with a speed of 60 mph.

The water level in the river is an illustration of a linear function

The linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]

From the complete question, we have the following table:

t      w

1     18.7

1.5  19.1

Start by calculating the slope (m)

[tex]m = \frac{w_2 - w_1}{t_2 -t_1}[/tex]

This gives

[tex]m = \frac{19.1 - 18.7}{1.5 - 1}[/tex]

Evaluate

[tex]m = 0.8[/tex]

The equation is then calculated as:

[tex]w = m(t - t_1) + w_1[/tex]

So, we have:

[tex]w = 0.8(t - 1) +18.7[/tex]

Expand

[tex]w = 0.8t - 0.8 +18.7[/tex]

[tex]w = 0.8t + 17.9[/tex]

Hence, the linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]

Answer:

As the lines are parallel, it shows that the two lines form 180° because they are angles on the same side of the transversal. A transversal is a line that bisects two lines.

Here,

(20x + 5)° + (24x - 1)° = 180°

=> (20x + 24x)° + (5 + (-1)  )° = 180°

=> 44x° + 4° = 180°

=> 44x = (180 - 4)°

=> x = 176 / 44

=> x = 4

Therefore, x = 4 is the solution of the equation.
