Answer:
50mph
Step-by-step explanation:
Say for example car A increases by 10 miles per hour and car B decreases by 10 miles per hour. If car A2 = car B3 then by eliminating a few numbers and finally get to 50 you get the following equation.
A = 50+10
b = 50-10
A = 60
B = 40
A2 = 120
B3 = 120
120 = 120
Answer
120km
Step-by-step explanation:
let s = the original speed
Write a distance equation; dist = time * speed
3(s-10) = 2(s+10)
3s - 30 = 2s + 20
3s - 2s = 20 + 30
s = 50 km/hr is the original speed
confirm this, find the distances
3(50-10) = 120 km
2(50+10) = 120 km
Some 10-13 year olds were asked where to buy snacks. If 12% or 24 children, said a convenience store, how many children were asked to buy snacks?
Answer:
200 children
Step-by-step explanation:
so 12% is 24 children
12/24
simplify
1/2
1% is 2 children
multiply 1% by 100 to get 100%, along with 2 for the children
200 children
if tenths of 5 + sqrt 11 is A and 5 - sqrt 11 is B and C is A+B. find c.
help me plzz!
Answer: 1.5
Step-by-step explanation: Given:
A=1/10×5 + 11²
B= 5 - 11²
If c = A + B
c = ( 1/10×5 +11²) + ( 5 - 11² )
= ( 5/10 + 121) + ( 5 - 121)
= ( 121.5) + ( -120)
= 121.5 - 120
= 1.5

In triangle JKL, JKL is a right angle, KM and is an altitude. JL=20 and ML=15, find KL
Answer:
KL = 17.32
Step-by-step explanation:
KL² = (M L)(J L)
KL² = (15)(20)
KL²=300
√KL²= √300

Find the slope of the line that passes through the points A(–3, 1) and B(2, –5).
PLZ ANSWER ACCURATELY AND QUICKLY WILL MARK BRAINLIEST
Answer:
- 6/5
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( -5-1)/(2- -3)
= (-5-1)/(2+3)
- 6/5
Answer:
-6/5 or -1 1/5
Step-by-step explanation:
The formula to find the slope with any 2 points of a line is rise/run, or
(y2-y1)/(x2-x1)
In this case, y2 is -5, y1 is 1, x1 is -3, and x2 is 2.
So, the slope is:
(-5-1)/(2-(-3))
-6/5 which, as a mixed number, is -1 1/5.
You can also graph out the points on a coordinate plane, draw the line between the points, and count the rise/run, but that might take a minute or two, which is not the best if you have a timed test.

The animal shelter needs to split 6 1/2 pounds of dog food equally among the 13 dogs in the facility. How much dog food will each dog receive?
Answer:
1/2 pound for each dog.
Step-by-step explanation:
Don't get confused. There are only 2 numbers which will give 2 different answers: 2 and 1/2. Which one is correct?
You want the units to be pounds per dog or pounds/ number of dogs.
The numerator is 6.5
The denominator is dogs (13)
Food per dog = 6.5 / 13 = 1/2
Write an absolute value equation to satisfy the given solution set shown on a number line.
<————•—————————-•——————->
-1/2 1/2 a
Thanks!
An absolute value equation to satisfy the given solution set shown on a number line is -1/2 ≤ a ≤ 1/2.
What is magnitude and sign?A number has both magnitude(its absolute value) and its sign(positive or negative).
Thus, for -5, the magnitude is 5, and sign is –ve.
Also, positive numbers > 0 > negative numbers.
In the number line we can clearly see that our possible values of a are in the range:
-1/2 ≤ a ≤ 1/2
And we need to find an absolute value equation such that this set is the set of possible solutions.
An example can be:
Ia - 1/2I ≤ 1/2
Notice; using the minor and equal sign, this is because the black dots means that the values a = -1/2 and a = 1/2 are included, if the dots were empty dots, it would be an open set and we should use the < > signs.

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?
Answer:
A = 24 in^2
Step-by-step explanation:
A = 1/2 bh
Let b = 8 and h = 6
A = 1/2 (8)(6)
A = 24 in^2
The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?
Solution :Given Data :
Height = 6 inches
Base = 8 inches
Formula for Area of traingle is :
[tex] \: \: \: \: \: \: \: \: \: \: \: \: \: \: \star \: \: \: \red{ \underline{ \red{ \overline{ \orange{ \boxed{ \pink{\frak{Area \: of \: Triangle = \frac{1}{2} × Base × Height }}}}}}}}[/tex]
So, putting the values of Base and Height we get
[tex] \leadsto \frak{Area = \frac{1}{2} × 8 \times 6 }[/tex]
[tex] \leadsto \frak{Area = \frac{1}{ \cancel2} × \cancel 8 \times 6 }[/tex]
[tex] \leadsto \frak{Area = 4 \times 6 }[/tex]
[tex] \leadsto \frak{Area = 24 \: {in}^{2} }[/tex]
Hence, the area of the traingle is 24 inches²
