Answer:
70
Step-by-step explanation:
Using the similarity theorem;
AB/BC = AD/AB
x/7+3 = 7/x
x/10 = 7/x
x^2 = 70
x = √70
Hence the required value inside square root is 70

Answer:
MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8

) The diagram shows a quadrant of a circle . If the curved edge is 15 cm long, what is the length of a straight edge?
Answers
Answer:
9.55 cm
Step-by-step explanation:
A quadrant of a circle is 1/4 of a circle.
Since the curved edge is 15 cm, a full circle would be 60 inches.
60/Pi = diameter
diameter = 60/3.14 = 19.11 cm
diameter/2 = radius
radius = 19.22/2 = 9.55 cm which is the length of a straight edge.
Marty has a driveway that is 200 feet long. The tires on her car have a diameter of 18 inches. What is the fewest number of tire rotations a tire will make tot travel the entire distance of the driveway?
Answers
The the fewest number of tire rotations is 42 to travel the entire distance of the driveway.
It is given that the driveway that is 200 feet long and the tire diameter is 18 inches.
It is required to find the fewest number of tire rotations a tire will make to travel the entire distance of the driveway.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
Driveway length = 200 feet
Diameter of the tire = 10 inches
For converting it to feet divide by 12.
Now the diameter of tire = 18/12 = 1.5 feet
Radius of the tire = 0.75 feet
We know the perimeter of the circle:
[tex]\rm P = 2\pi r[/tex]
P = 2(π)(0.75)
P = 4.71 feet ( π =3.14 and P = 0.75)
[tex]\rm number \ of \ tire \ rotations = \frac{Driveway \ length}{Perimeter \ of tire}[/tex]
[tex]= \frac{200}{4.71}[/tex]
Number of tire rotation = 42.462 ≈ 42
Thus, the the fewest number of tire rotations is 42 to travel the entire distance of the driveway.

Write a system of linear equations for the problem below(you do not have to solve it) Twenty-six students attended the community service event. The number of girls was 4 fewer than twice the number of boys. How many boys attended the community service event?
Answers
Answer:
Number of boys who attended the community service event = 10
Step-by-step explanation:
Let [tex]x[/tex] denotes number of girls and [tex]y[/tex] denotes number of boys.
Twenty-six students attended the community service event.
So,
[tex]x+y=26[/tex]
The number of girls was 4 fewer than twice the number of boys.
[tex]x=2y-4[/tex]
Put [tex]x=2y-4[/tex] in [tex]x+y=26[/tex]
[tex]2y-4+y=26\\3y=26+4\\3y=30\\y=10[/tex]
So,

Amy wrote a 10 sided die numbered one through 10 what is the probability that she will hold a number divisible by four
Answers
Answer:
2/10 or 20%
Step-by-step explanation:
Because 4 and 8 are the only numbers 1-10 that are divisible by four.
This would give Amy a 2/10 chance of rolling a number divisible by 4.
To turn 2/10 into a percent, the denominator has to be 100 so if you multiply 10 by 10 you will get 100, you will also have to multiply 2 by 10 to get 20 and you will get 20/100
20/100 is equal to 20%
Therefore your answer would be 2/10 or 20%

2 The length of this rectangle is x cm.
a The width of the rectangle is 2 cm less than the length.
Write down an expression for the width of the rectangle, in centimetres.
b The perimeter of the rectangle is 84 cm. Write down an equation to show this.
c Solve the equation.
d Find the area of the rectangle.
Answers
Answer:
a. The width of the rectangle is x-2cm
b. length is 21.5 cm and breadth is 19.5cm
c. area is 419.25 cm sq.
Step-by-step explanation:
Let the length be x and the breadth be x-2
perimeter = 84 = 2(l+b) = 2×(x+x-2)
2×(2x-2)=84
4x-2 = 84
4x = 86
x= 86/4
x= 21.5
length is 21.5 and breadth is 21.5-2 = 19.5
area = l×b
= 21.5 ×19.5
= 419.25cmsq.

[tex] \purple { \bold{ a_{10}=161414428}}[/tex]
Step-by-step explanation:
Given sequence is: 4, 28, 196, 1372
28/4 = 7
196/28 = 7
1372/196 = 7
Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.
Therefore,
Common ratio r = 7
First term a = 4
nth term of a geometric sequence is given as:
