Answer:

It is 285

Step-by-step explanation:

(1 2/3)% × (it) = 4.75

Of course, 1 2/3 = 5/3 and x% = x/100, so when we divide the above equation by (1 2/3)%, we get ...

(it) = 4.75/((5/3)/100) = 4.75×(300/5)

(it) = 285

ASAP!!! Which of these graphs could represent an exponential relation (Explain)

Margarita [4]

Answer:

B. looks like the best answer that fits this question.

If i'm wrong then my fault.

Step-by-step explanation:

When looking at choice (B) you can see it started at a decreasing point but slowly growing. Exponential relations are images or equations that describe growth and they always have the same function. If you look at the other choices you see that they either increase but then decrease or they don't match the formula for (exponential relations).

That's as good as I can do I dont knw if this what ur teacher is looking for but I tried :/

The length of one base of a trapezoid is 19 less than five times the length of the other base. If the trapezoid has a height of

ycow [4]

The length of the longer base is 41 ft.

Explanation

Lets assume, length of one base is $x$ ft.

As, another base is 19 less than five times the length of this base, so the length of another base $= (5x- 19) ft.$

The trapezoid has a height of 18 ft and area of 477 ft²

Formula for Area of trapezoid, $A=\frac{1}{2} (a+b)*h$ , where $a, b$ = Two bases of trapezoid and $h$ = height of the trapezoid.

Given in the question: $A= 477$ and $h= 18$

We have also two bases as: $a= x$ and $b= 5x-19$

So, according to the above formula...

$A= \frac{1}{2}(a+b)h\\\\ 477=\frac{1}{2}(x+5x-19)*18\\\\ 477=9(6x-19)\\\\477= 54x-171\\\\477+171=54x\\\\648=54x\\\\x=\frac{648}{54} = 12$

So, length of one base is $12 ft$ and another base $=(5*12-19)ft =(60-19)ft = 41 ft$

That means, the length of the longer base is 41 ft.

the relationship between the x- and y- values in each table is linear. write a function. find the amount and rate of change. (5

Doss [256]

(5)

Since, the relationship is linear

so, we can use point slope form of line and find equation of line

we can select any two points

first point is (4,10)

so, x1=4 , y1=10

second point is (7,17.5)

so, x2=7 , y2=17.5

now, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{17.5-10}{7-4}$

$m=2.5$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

now, we can plug values

$y-10=2.5(x-4)$

we get

$y=2.5x$

Initial amount:

It is the value of y when x=0

so, we can plug x=0 and find y

$y=2.5\times 0$

$y=0$

So, initial amount is 0

Rate of change:

we know that rate of change is slope

so, m=2.5

so, the rate of change is 2.5

(6)

Since, the relationship is linear

so, we can use point slope form of line and find equation of line

we can select any two points

first point is (2,29)

so, x1=2 , y1=29

second point is (5,41)

so, x2=5 , y2=41

now, we can find slope

$m=\frac{y_2-y_1}{x_2-x_1}$

now, we can plug values

$m=\frac{41-29}{5-2}$

$m=4$

now, we can use point slope form of line

$y-y_1=m(x-x_1)$

now, we can plug values

$y-29=4(x-2)$

we get

$y=4x+21$

Initial amount:

It is the value of y when x=0

so, we can plug x=0 and find y

$y=4\times 0+21$

$y=21$

So, initial amount is 21

Rate of change:

we know that rate of change is slope

so, m=4

so, the rate of change is 4
