a² + b² = c²
c² - b² = a²
10² - 8² = 36²
Square root of 36 = 6 inches
Answer:
6 in
Step-by-step explanation:
hypotenuse (h) = 10 in
base (b) = 8 in
perpendicular (p) = ?
we know that by using Pythagoras theorem
p = √h² - b²
= √10² - 8²
= √ 36
= 6
3kg of apples and 8kg of grapes costs €7.60 in total 5kg of apples and 3kg of grapes costs €7.50in total work out the costs of a kg of each type of fruit
Answer:
1kg of apple : €0.50
1kgof grapes : €1.20
Step-by-step explanation:
15kg of apples and 40kg of grapes costs €38
15kg of apples and 9kg of grapes costs €22.50
38 - 22.50 = 15.5
40 - 9 = 31
15.5 ÷ 31 = 0.5 ( 1kg of grapes )
0.5 × 3 = 1.5
7.5 - 1.5 = 6
6 ÷ 5 = 1.2 ( 1kg of apples )

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent? Write an equation to represent this situation.
Answer:
y = 2/3xStep-by-step explanation:
Reading rate is y pages per x minutes and proportional relationship formula is:
y = kxThe coefficient is:
k = y/xLet's verify if the given numbers fit into the same relationship:
12/18 = 2/38/12 = 2/320/30 = 2/3We confirm all same and it means k = 2/3
Required equation is:
y = 2/3xThis represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages

y = –x + 4 in standard form
Answer:
x-y=4
Step-by-step explanation:
y=x−4
The standard form of a linear equation is
Ax+By=C.
Rewrite the equation with the sides flipped.
x−4=y
Move all terms containing variables to the left side of the equation.
Tap for more steps...
x−y−4=0 Add 4
to both sides of the equation.
x−y=4

Answer:
It's expansion.
Step-by-step explanation:
Answer:
Scale factor of k results in expansion if:
| k | > 1and the contraction if:
| k | < 1Given values:
-5/4 ⇒ expansion3/8 ⇒ contraction-1.2 ⇒ expansion0.5 ⇒ contractionWhat is the minimum velocity attained on the interval 0
Answer:
0.630
Step-by-step explanation:
Simply evaluating, we get v (0) = 1, v (0.31831) = 0.630, v (2) = 1.566. Thus, the minimum velocity over the interval [ 0, 2] is 0.630.

Please answer as quickly as you can! ♥ Find two possible dimensions for a cylinder that has a volume of 64π cm³.
Answer:
Possible dimensions are [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex] and [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]
Step-by-step explanation:
Given:
Volume of a cylinder is [tex]64\pi\,\,cm^3[/tex]
To find: Dimensions of a cylinder
Solution:
Let [tex]r,h[/tex] denote height of a cylinder.
Volume of a cylinder = [tex]\pi r^2h[/tex]
Therefore,
[tex]64\pi=\pi r^2h\\64=r^2h\\4^2\,4=r^2h[/tex]
One possible dimension can be [tex]r=4\,\,cm\,,\,h=4\,\,cm[/tex].
Also, [tex]64=r^2h[/tex] can be written as [tex]16(2^2)=hr^2[/tex]
So, another possible dimension can be [tex]h=16\,\,cm\,,\,r=2\,\,cm[/tex]

Which equation matches the graph? points. (-5,1) (0,-3)
a. y= -4/5x-3
b. y= -5/4x-3
c. y=-4/5x+3
d. y= -5/4x+3
Answer:
-4/5x-3
Step-by-step explanation:
We can eliminate the options C and D as they have a +3 which means they would start at (0,3).
y=-4/5x-3
y=-4/5(-5)-3
y=4-3
y=1
same thing from last question
1=-4/5x-3
+3 to both sides
4=-4/5x
*5/4 to get 1x
5=-x
*-1 to get positive x
-5=x
which proves my answer as correct
The given point 1, -3 reflected over the x axis
Answer:
(1,3)
Step-by-step explanation:
The image of (1, -3) is (1, 3).
What is a reflection?There are two ways of reflection.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
Point = (1. -3)
Reflected over the x-axis.
So,
(1, -3) = (1, -(-3)) = (1, 3)
Thus,
(1, 3) is the reflected image.

Let b= 7.
3b+-4
Please help
Answer:
b=40/63
Step-by-step explanation:
b= 7. 3b+-4
multiply both sides by 10
b*10=7.3b*10-4*10
refine
b*10=7.3b-40
subtract 7.3b from both sides
b*10-7.3b=7.3b-40-7.3b
simplify
-63b=-40
divide both sides by -63
-63b/-63=-40/-63
simplify
b=40/63
