Answer:
x=16
Step-by-step explanation:
let:
> x be one number
> y be the other number
system of Equations:
> x+y=8
> x-y=24
Using elimination method the y's cancel each other out, and we are left with
2x = 32
divide by 2 on both sides to get x by itself
AND
x=16

Ab is tangent to circle o at a. the diagram is not drawn to scale. if ao =30 and bc = 48 what is ab?
a) 84
b) 78
c) 76
d) 72
Answer:
91.19
Step-by-step explanation:
From the given diagram;
BO = 2 BC
BO = 2(48)
BO = 96
To get AB, we will use the pythagoras theroem;
BO² = AB² + AO²
96² = AB² + 30²
9216 = AB² + 900
AB² = 9216 - 900
AB² = 8,316
AB = √8,316
AB = 91.19
Hence the length of AB is 91.19

A homeowner puts a patio in the northwest corner of a square backyard. The area of the patios is 750
square feet. What is the area of the backyard?
120 ft
X
25
xft
Answer:
17.6621ft²
Step-by-step explanation:
First we need to find the side length of the patio x
SInce the area of the patio = 750
Area of patio = x * x
Area of patio = x²
750 = x²
Swap
x² = 750
x = √750
x = 27.39ft
Length of the backyard = 27.39ft - 25ft = 2.39ft
Width of the backyard = 27.39ft - 20ft = 7.39ft
Area of the backyard = 2.39 * 7.39
Area of the backyard = 17.6621ft²
The dimension of the backyard is 7.4 feet by 2.4 feet. Then the area of the backyard is 17.76 square feet.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
A homeowner puts a patio in the northwest corner of a square backyard. The area of the patios is 750 square feet.
The dimension of the patio will be
x² = area
x² = 750
x = 27.4 feet
The dimension of the backyard will be
Length = 27.4 – 20 = 7.4
Width = 27.4 – 25 = 2.4
The area of the backyard will be
Area of backyard = 7.4 × 2.4
Area of backyard = 17.76

What is an equation of the line that passes through the point (-5,-2)and is parallel to the line x-y=5?
Answer:
[tex]y=x+3[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines always have the same slope (m)1) Determine the slope (m)
[tex]x-y=5[/tex]
Rearrange this given equation into slope-intercept form. This will make it easier for us to identify the slope.
Subtract x from both sides of the equation
[tex]x-y-x=-x+5\\-y=-x+5[/tex]
Divide both sides by -1 to isolate y
[tex]y=x-5[/tex]
Now, we can identify clearly that the slope of this line is 1. Because parallel lines have the same slopes, a line parallel to this one would also have a slope of 1. Plug this into [tex]y=mx+b[/tex]:
[tex]y=1x+b\\y=x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=x+b[/tex]
Plug in the given point (-5,-2)
[tex]-2=-5+b[/tex]
Add 5 to both sides
[tex]-2+5=-5+b+5\\3=b[/tex]
Therefore, the y-intercept of the line is 3. Plug this back into [tex]y=x+b[/tex]:
[tex]y=x+3[/tex]

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km

Anne made a recipe for miniature bread loaves that called for StartFraction 7 Over 8 EndFraction of a cup of whole-wheat flour. If the recipe made 7 equal-sized loaves of bread, how many cups of whole-wheat flour did each loaf contain?
StartFraction 1 Over 8 EndFraction of a cup
Answer:
8 loaves
Step-by-step explanation:
so each loaf contains 7/8 cups flour
there are 7 loaves
7 ÷ 7/8 = 8
Answer:
1/8
Step-by-step explanation:
So if the entire recipe makes 7 loaves and calls for 7/8 of a cup, you would need to split the 7/8 cups flour into 7. 7/8 ÷ 7=1/8.

64 ^1/4
What number multiply by itself 4 times =64
m*m*m*m = 64
Rewriting 64 as 16*4
(16*4) ^1/4
We can rewrite this as
16 ^ 1/4 * 4^1/4
We know 16 ^ 1/4 = 2
2 * 4 ^ 1/4
Answer:
4
Step-by-step explanation:
64 ¼
Any number multiply by itself 4 times = 64
Let no. be x.
x × x × x × x = 64
x ⁴ = 64
Taking square root of each side
√ x⁴ = √64
x² = 8
Now, again Taking square root
√x² = √8
x = 4
