Answer:
AB = 2
Step-by-step explanation:
Using the secant- secant theorem, that is
PA × PB = PD × PC , substitute values
10(10 + AB) = 8(8 + 7)
100 + 10AB = 8 × 15 = 120 ( subtract 100 from both sides )
10AB = 20 ( divide both sides by 10 )
AB = 2

Someone answer this for brainliest.
Answer:
x < 3
Step-by-step explanation:
4x - 7 < 5
Add 7 to both sides.
4x < -2
Divide by 4 to both sides to get x alone.
x < 3
To check the answer if it's right or not, you can just plug in the 3 for x and multiply it by 4 which would equal 12 and subtract 12 - 7 which would equal 5.
Hope this helps and pls do mark me brainliest:)

Renee can run 10 miles in 1.75 hours. Amy can run 8 miles in 1.5 hours who runs faster
Answer:
The person with the larger value means they are moving at a higher acceleration
Step-by-step explanation:
Renee: 10 miles / 105 minutes = 0.095 mi/min
Amy: 8 miles / 90 minutes = 0.088 mi / min
Anna runs three over4 mile in six minutes. Assuming she runs at a constant rate what is her speed in miles per hour
Answer:
7.5 mph
Step-by-step explanation:
6 times 10 is 60 minutes which is an hour

can a triangle have an exterior angle that is obtuse at two vertices? Explain
Answer:
Yes
Step-by-step explanation:
An obtuse triangle will have two obtuse angle at its exterior.
Take for instance, the angles in the triangle are 100, 40 and 40.
The exteriors would be 80, 140, 140 (this is gotten by subtracting each interior angles from 180).
So, using the above analysis, we can conclude that the statement is possible.
Evaluate each using the values given.
x-5-|xz|; use x = 8, and z=-10
A) -67 B) -80
C) -75 D) -77
If BC measures 8 inches, the approximate area of circle B is
square inches.
The area of the circle radius as 8 inches will be 201.062 inches².
What is a circle?A circle is a geometrical figure which becomes by plotting a point around a fixed point by keeping a constant distance.
In our daily life, we always see circular objects for example our bike wheel.
The longest line which can be drawn inside the circle will be the diameter.
Area of circle = πr² and the perimeter of circle = 2πr where r is the radius of the circle.
Given the circle with a radius BC of 8 inches.
Area of circle = πr² where r is the radius of the circle.
So,
Area = π(8)² = 201.062 inches.
Hence "The area of the circle radius as 8 inches will be 201.062 inches².

The slope of a line is 3/4. If x increases by 20, what is the corresponding change in y? Please explain the answer.
Answer:
15
Step-by-step explanation:
15 is three quarters of 20 and a gradient of a graph is how much the y axis increases when you increase the x axis value, so if it increases by a value then in this case we need 3/4 of this value, hence 15
Answer:
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
Try this Adjust the line below by dragging an orange dot at point A or B. The slope of the line is continuously recalculated. You can also drag the origin point at (0,0).

-2(2x+60) - 2x = -2(1/5x+6)
Answer:
x = -135/7 or -19.3 (rounded to the tenths)
Step-by-step explanation:
-2(2x+60)-2x=-2(1/5x+6)
First Distribute:
−4x+−120+−2x= −2/5 x+−12
Add Like Terms:
-6x-120= -2/5 x-12
Add -2/5x to each side:
−28 /5 x−120=−12
Add 120 to each side:
−28 /5 x =108
Multiply by (5/-28):
x = -135/7 or -19.3

When Lucy left her house in the morning, her cell phone battery was partially charged. Lucy's phone lost battery life at a rate of 8% each hour and 3 hours after leaving her house, the battery had 16% remaining battery life. Write an equation for B , B, in terms of t , t, representing the charge remaining in Lucy's battery, as a percentage, t t hours after Lucy left her house.
Answer:
B = 40 - 8t
Step-by-step explanation:
Given that:
Rate at which battery life discharges = 8% per hour ;
Battery life left after 3 hours = 16%
t = hours after Lucy left hiuse
Equation B will be ;
Amount of charge before leaving home - (Discharge rate * number hours)
Amount of charge before leaving home :
Charge left after 3 hours + discharge rate * 3
16% + 8*3
16% + 24% = 40%
Hence,
B = 40 - 8t
Answer:
probably B = 40 - 8t
