Take that certain number we are looking for as 'n'

38% ⇒ 0.38

0.38n = 152

Divide by 0.38

0.38n = 152
/0.38 /0.38

n = 400

So 38% of 400 is 152.

Ratio and proportion
152/x=38/100
cross multiply
38x= 15200
divide by 38
x= 400

hope this helps

In ΔCDE, the measure of ∠E=90°, the measure of ∠D=23°, and EC = 1.3 feet. Find the length of DE to the nearest tenth of a foot.

BabaBlast [244]

Answer: length of DE is about 3.3 ft

Step-by-step explanation: A calculator is necessary!

DE is the unknown hypotenuse of the triangle

get the sine of 23° = 0.3907311285

Use the equation for sine

sin = o/h .

To find h, Substitute values for sin and o. O is EC, Opposite the 23° angle D

0.3907311285 = 1.3/h multiply both sides by h

h(0.3907311285) = 1.3 divide both sides by 0.3907311285

h = 1.3/0.3907311285

3.327096065 = h, the length of the hypotenuse, DE.

Haynes High School chartered buses for 60 students to go on a field trip. Valley High School chartered buses for 80 students.

Svetradugi [14.3K]

Answer: $20

Step-by-step explanation:

Let 'x' be the cost of a ticket at Haynes

Let 'y' be the cost of a ticket at Valley

Since the total cost from both schools are the same, we can write it as:

$60x=80y$

Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:

$y=x-5$

Now we have two equations, we can use to substitute into the other expression:

$60x=80y$

$60x=80(x-5)$ we substitute y in this equation with the other equation

$60x=80x-400$

$-20x =-400$

$x = 20$

Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.

ILL MARK BRAINIEST IF YOU CAN DO THIS RIGHT!!!

Bumek [7]

Answer: Slope: -1/2

Step-by-step explanation: To find slope take 2 points that lie on the line and use this formula to solve: I will use (0, -2) and (2, -3) to solve

↑ ↑ ↑ ↑

y2 - y1 x1 y1 x2 y2

-----------

x2 - x1

So, for this question, substitute the x and y values from the points above to solve.

-3 - (-2)

----------- = - 1/2

2 - 0

Hope this helped. :)
