A pitcher throws a fast ball at a speed of 89 miles per hour (mph), how fast did the ball travel in feet per second (ft/sec)? a. 89 Ft sec b. 469,920 sec c. 130.5 ft d. 60.7 . ft sec sec
Can someone explain this? :)
I'll do part (a) to get you started.
The angle 'a' pairs up with the 123 degree angle as a corresponding angle pair. Due to the parallel lines, the corresponding angles are congruent. Therefore a = 123.
We also see that b = 123 as well since a = b (they are vertical angles).
Notice how angle c is adjacent to the 123 degree angle. These two angles form a straight line, so they must add to 180 degrees.
c+123 = 180
c = 180-123
c = 57
-------------------------
To summarize, we have these three angles
a = 123
b = 123
c = 57
Answer:
a) a=57° b=123° c=123°
b) f=98° d=98° e=98°
c) g=75° h=75°
Step-by-step explanation:
a) a°+123°=180° (angle on a straight line=180°)
a°=180°-123°
a°=57°
b°=123° (alternative angles)
c=123° (vertically opposite angles are equal)
b)f+82°=180° (angle on a straight line=180°)
f=180°-82°
f=98°
f=d (corresponding angles are equal)
d=e (vertically opposite angles are equal)
c) h=75° (corresponding angles are equal)
g=h (vertically opposite angles are equal)
What is 127 divided by 4
The value of expression 127 divided by 4 would be; 31.5
When 'a' is divided by 'b', then we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find the expression of 127 divided by 4.
A negative divided by a negative is positive, then;
Therefore, 127 ÷ 4 = 31.5
Therefore, The value of expression 127 divided by 4 would be; 31.5

The difference between high and low tides along the Maine coast one week is 19 feet on Monday and x feet on Tuesday. Write an expression to show the average difference between the tides for Monday and Tuesday. (will give brainliest,)
Answer: 19 + × / 2
Step-by-step explanation:
Look for the key words:
Rise AND fall of the tide = Addition (19+x)
To show the AVERAGE = Division (Divide it by 2 because there is Monday and Tuesday)
The average difference between the tides for Monday and Tuesday Expression is 1/2×(19 + x)
Average difference Expression = 1/2 ×(19 + x)
Where:
19 represent the Difference between high and low tides on Monday
x represent Difference between high and low tides on Tuesday
Inconclusion The Average difference Expression is 1/2 ×(19 + x)

A bakery van has an original value of $40,000. The van is depreciating at a rate of 9% each year. About
how much will this van be worth 5 years later?
Answer:
$22,000
Step-by-step explanation:
9 percent of 40000 is 3600
it depreciates for 5 years so times 5 which gives us 18000
now subtract this amount from its original value and you get 22,000

A force of 125 newtons stretches a spring 0.15 meters. What force is required to stretch it 0.25 meters??
show procedure
Answer:
Step-by-step explanation:
A spring has a force formula of F = k*x
f = 125 N
x = 0.15 m
125 = k*0.15
k =833.33
F = ?
k = 833.33
x = 0.25 m
F = 833.33 * 0.25
F = 208.33 N
You could do this without solving for k
F1/F2 = x1/x2
F1 = 125 N
F2 = ?
x1 = 0.15
x2 =0.25
125 / F2 = 0.15 / 0.25 Cross multiply
125 * 0.25 = 0.15 * F2 Divide by 0.15
125*0.25 /0.15 = F2
F2 = 208.33 just as you got above

an elevator in a tall building goes up 7 floors, then down 9 floors, down 4 floors, up 8 floors, anddown 2 floors. now it is on floor 14 on what floor did the elevator start
Answer:
It started on the same floor, floor 14
Step-by-step explanation:
if it went up 7 then down 9, so negative 2 kinda, then down another 4, so negative 6, then up 8 so positive 2, then down 2, it would've started on floor 14
Answer:
14
Step-by-step explanation:
Let the floor started be 'x'
Equation:-
=> x + 7 - 9 - 4 + 8 - 2= 14
x + (+7) + (-9) + (-4) + (+8) + (-2) = 14
x + 7 - 9 - 4 + 8 - 2 = 14
x + 15 - 15 = 14
x = 14
Therefore, elevator started from 14th level.

Answers:
a) -3b) 7/3c) -1/2d) 1/11e) undefinedf) 0d) 2/3========================================================
Explanation:
If the original slope is a/b, then the perpendicular slope is -b/a
We flip the fraction and we flip the sign from positive to negative, or vice versa.
As an example, the slope 1/3 flips its fraction to 3/1 or just 3. Then we flip the sign to -3. So if the original slope is 1/3, then its perpendicular counterpart is -3.
Notice how the two slopes multiply to -1
(1/3)*(-3) = -1
This applies to any pair of perpendicular lines such that neither line is horizontal and neither line is vertical either.
------------------------
If the original slope is some whole number, then rewrite it as a fraction over 1
Example: 2 becomes 2/1
That way we can flip the fraction and the sign
-------------------------
If we had an original slope of 0, then it's the same as 0/1
Flipping the fraction leads to 1/0, but that's undefined. We cannot divide by zero. So that explains the answer to part e).
Going in reverse of this process, any line with undefined slope will be perpendicular to lines of slope 0.
horizontal lines have slope of 0
vertical lines have undefined slopes
-------------------------
For part g), you'll need to convert from a mixed number to an improper fraction
Use this formula
a & b/c = (a*c + b)/c
So this means,
1 & 1/2 = (1*2 + 1)/2 = 3/2
which leads to
-1 & 1/2 = -3/2
Then applying the rule "flip the fraction flip the sign" gets us from -3/2 to 2/3.
Select the equivalent expression.

Answer:
x = 70
Step-by-step explanation:
50 + x + 2x + 100 = 360
Combine like terms
3x + 150 = 360
Subtract 150 from both sides
3x = 210
Divide both sides by 3 to isolate x
x = 70
