Strip diagram is a tool that is used to be able to solve the given problem accurately.
I will show you how to do it.
we have 136 ounces that needs to be convert to cups
1 ounce = 0.125 cup
In 1 cup = 8 ounce
136 ounces / 8 cups = 17 cups
Answer:
y = -3x +5
Step-by-step explanation:
parallel lines so slope of the lines will be equal.
m1 = m2
y = mx + b,
y = -3x + b
substituting y = -1 and x = 2
-1 = -3(2) + b
-1 = -6 + b
therefore, b = -1 + 6
b = 5
by substituting b = +5
therefore, the equation is,
y = -3x + 5
Answer:
n = 7/2
Step-by-step explanation:
4n^2-22=27
4n^2 = 27 + 22
4n^2/4 = 49/4
sqrtn^2 = sqrt(49/4)
n = 7/2
Answer:
A) 480cm^3
B) 35 cm^2
Step-by-step explanation:
Given two similar solids
Volume of A = 60cm^3
Surface area of B = 140cm^2
Side A = 3
Side B = 6
NB: if two solids are similar, the ratio of their volume equals the cube of the corresponding proportion of their linear measure.
That is :
Volume A / volume B = (side A / side B)^3
(60 / volume B) = (3 / 6)^3
(60 / volume B) = (1/2)^3
(60 / volume B) = (1/8)
Volume B = 480cm^3
B) the surface area:
NB: if two solids are similar, the ratio of their surface areas equals the square of the corresponding proportion of their linear measure.
Surface area A / surface area B = (side A / side B)^3
(surface area A / 140) = (3 / 6)^2
(surface area A / 140) = (1/2)^2
(surface area A / 140) = 1/4
4 × surface area A = 140
Surface area A = 140/4
Surface area of A = 35cm^2
Answer:
That is a cyclic quadrilateral. (A quadrilateral that is inscribed in a circle.)
In a cyclic quadrilateral, opposite angles sum to 180°
Therefore 3y + 8 + y = 180°
4y = 172
y = 43
Therefore angle R = 137
