Answer:
part A; B and Part B; pencils
Step-by-step explanation:
you want to find out how many pens and pencils you cn buy with that 90$ so you want to do
.75y+.15x=90
pens=50
pencils=50
but you want to add .75+.15 which = .90
then you divide 90/.90
and that equals 100
then split it up and each gets 50
Speed = distance / time
30 = d / 2.5
30 * 2.5 = d
75 = d
40 = d / 1.875
40 * 1.875 = d
75 = d
50 = d / 1.5
50 * 1.5 = d
75 = d
60 = d / 1.25
60 * 1.25 = d
75 = d
24 = 75 / time
time = 75/24
time = 3.125 hours
In order to find the missing number use the Pythagorean theorem which is used to find a missing length of a right triangle. The formula is a 2 + b 2 = c 2, where a and b are the legs of the triangle, and c is the hypotenuse. So the answer would be 22squared plus 27squared which will equal....
Hi there!
5k - 2k = 12
Solve for K
3k = 12
Divide both sides by 3
3k/3 = 12/3
k = 4
The correct answer is : 4
I hope that helps!

Answer:
<u>The length of the longer segment of the 50 cm chord = 40</u>
Step-by-step explanation:
let the length of the longer segment of the 50 cm chord = x
so, the other segment = 50 - x
A chord of 50 cm bisects a chord of 40 cm
using the Intersecting Chords Theorem
so, x(50-x) = 20 * 20
50x - x² = 400
x² - 50x + 400 = 0
(x - 40)(x - 10) = 0
x = 40 or x = 10
<u>So, the the length of the longer segment of the 50 cm chord = 40</u>
