Miss Lianto mowed 2/7 of her lawn. Her son mowed 1/4 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
HURRY AND BE CORRECT PLEASE!!!
Answers
Answer: 2/7 = 8/28
1/4 = 7/28
Therefore Mr Pham mowed more.
8+7 = 15 so 15/28 of lawn has been mowed, therefore 13/28 of the lawn is left still to be mowed.
Mr. Pham mowed more of the lawn than his son.
it still needs ¹³/₂₈ of the lawn to be mowed.
Step-by-step explanation:
Answer: 1/4 is greater than 2/7 mowed most of the lawn.
Step-by-step explanation:
First, draw a fraction model for [tex]\frac{2}{7}[/tex] and [tex]\frac{1}{4}[/tex] and partition it. Then, how ever many you get write it as a fraction. Then, see whose answer is greater.

The semicircle below has diameter $20$. Find the area of the blue region.
Answers
Area of the blue region is 61 units²
Area of semi circlearea = π / 2 r²
Therefore,
r = radius
Area of the blue region = area of semi circle - area of triangle
Therefore,
area of triangle = 1/bh
where
b = base
h = height
Therefore,
area of triangle = 1 / 2 × 12 × 16 = 96 units²
area of semi circle = 3.14 × 10² / 2 = 157 units²
Area of the blue region = 157 - 96 = 61 unit²

The simplification of the expression (9/4x + 6) - (- 5/4x - 24) will be 3.5x + 30.
What is simplification?Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ (9/4x + 6) - (- 5/4x - 24)
Simplify the expression, then we have
⇒ (9/4x + 6) - (- 5/4x - 24)
⇒ (9/4)x + 6 + (5/4)x + 24
⇒ (14/4)x + 30
⇒ 3.5x + 30
The simplification of the expression (9/4x + 6) - (- 5/4x - 24) will be 3.5x + 30.

Ava is in a hot air balloon that has just taken off and is floating above its launching point. Mary is standing on the ground 4 meter away from the launching point. If ava and mary are 5 meters apart, how high up is ava ?
Answers
Answer:
Ava's altitude is 3 meters.
Step-by-step explanation:
The position of Ava and Mary can be described by the sides of a right angled triangle. Let Ava's altitude be represented by x.
So that applying the Pythagoras theorem, we have;
[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]
[tex]5^{2}[/tex] = [tex]4^{2}[/tex] + [tex]x^{2}[/tex]
25 = 16 + [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 25 - 16
= 9
x = [tex]\sqrt{9}[/tex]
= 3
x = 3 meters
Thus, Ava's altitude is 3 meters.

X = 15
PQ = 26
Answers
Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:
[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]
[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]
[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]
This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
Answer:
x = 15, PQ = 26
Step-by-step explanation:
x+13/9 = 21/x-9
x^2+4x−117=168
x^2+4x−285=0
(x−15)(x+19)=0
x=15
it cannot be a negative number so x cannot be -19
PQ= x+13
15+13=26

The perimeter of a football field in a certain school is 296m. If the breadth is 2/3 of the length, find the sides of the field
Answers
Answer: 88.8 m , 59.2 m
Step-by-step explanation:
Given
Breadth is [tex]\frac{2}{3}[/tex] of length
Suppose length is x m
So, breadth is [tex]\dfrac{2}{3}x[/tex]
Perimeter is given by [tex]P=2(L+W)[/tex]
Putting values
[tex]\Rightarrow 296=2(x+\dfrac{2}{3}x)\\\\\Rightarrow 296=2(\dfrac{5}{3}x)\\\\\Rightarrow x=\dfrac{296\times 3}{10}=88.8\ m[/tex]
Length L is [tex]88.8\ m[/tex]
width W is [tex]\frac{2}{3}x=59.2\ m[/tex]

-22 - 49 = ?
11 - ( -12) = 11 + 12 = 23
-22 - 49
subtracting a negative from a negative is like adding a positive to a positive it has the same affect just a different sign
