Answer:
1.x=45,2.x=16
Step-by-step explanation:
1.
x+90+45=180(Angles in an adjacent angle)
x=180-135
x=45
2.
7x=112(vertically opposite angle)
x=112/7
x=16
First question refers to the supplementary angle theorem.
To find x, we need to refer to the other angles around it and use it to subtract it from 180°.
90 + 45 + x = 180
135 + x = 180
x = 180 - 135
x = 45°
Second question refers to the vertical angles theorem, where it states that the angles that face in opposite directions are the same.
7x = 112
x = 112 ÷ 7
x = 16°

Answer:
Step-by-step explanation:
Amount she gets in a day = number of flower * cost of each flower
= (25x² +5x + 5)*5x
= 25x²*5x + 5x *5x + 5*5x
= 125x³ + 25x² + 25x
Amount she gets in 5 day = (125x³ +25x² + 25x)* 5
= 125x³*5 + 25x² *5 + 25x *5
= 625x³ + 125x² + 125x

Answer:
10218.75
Step-by-step explanation:
You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:
For the rectangle:
37.5*22.5 = 843.75
For the triangle:
To find the base: 75 - 37.5 = 37.5
To find the height, use pythagoream theorem.
62.5² = 37.5² + b²
3906.25 = 1406.25 + b²
3906.25 - 1406.25 = 2500
√2500 = 50.
The height is 50, so 50*37.5(1/2)
= 937.5
Now add them together
937.5 + 843.75

3x/2 + 3y
Step-by-step explanation:
Given the expression 1/4 ( 3x + 4y ) + 3 ( 1/4 x + 2/3 y)
Open the parentheses
= 1/4(3x) + 1/4(4y) + 3(1/4x) +3(2/3y)
= 3/4 x + y + 3/4 x +2y
Collect like terms
3/4 x +3/4 x +y+2y
6/4 x + 3y
3x/2 + 3y
Hence the correct expression is 3x/2 + 3y

Jenny collects seashells and interesting rocks. She keeps her collections in boxes shaped like rectangular prisms. Her seashell box is 5 inches tall and has a volume of 200 cubic inches. Her rock box has a volume of 280 cubic inches. The area of the base of both boxes is the same. How tall is Jenny's rock box?
Answers
Answer:
7 in
Step-by-step explanation:
volume of a rectangular prism = width x height x length
width x length = area of the base
the sea shell box
200 = width x length x 5
width x length = 200/5 = 40cm^2
rock box
280 = 40in^2 x height
height = 280/40 = 7 in

For a given set of rectangles, the length varies inversely with the width. In one of these rectangles, the length is 2 and the width is 42. For this set of rectangles, calculate the width of a rectangle whose length is 7.
Answers
Answer:
Width = 12
Step-by-step explanation:
L = k/w
Where,
L = length of the rectangle
w = width of the rectangle
k = constant of proportionality
length is 2 and the width is 42
L = k/w
2 = k/42
k = 42 × 2
k = 84
calculate the width of a rectangle whose length is 7.
L = k/w
7 = 84/w
7w = 84
w = 84/7
w = 12
Width = 12
