Answer:
The scooter travels 15 feet in 1 second
The scooter travels 45 feet in 3 seconds
The scooter travels 60 feet in 4 seconds
The scooter travels 75 feet in 5 seconds
Step-by-step explanation:
First, let's find the number of feet the scooter travels in 1 second
(30 : 2) ÷ 2 = 15 : 1
Now that we have the unit rate, we can easily find the answers to the other questions.
(15 : 1) x 3 = 45 : 3
(15 : 1) x 4 = 60 : 4
(15 : 1) x 5 = 75 : 5
I Hope That This Helps! :)
Evaluate f(-2) for the function f(x)= -1/2x^2 + x + 1
Answer:
f(-2) = -3
Step-by-step explanation:
[tex]f(x)=-\frac{1}{2} x^{2} +x+1[/tex]
Just plug in x = -2
[tex]f(-2)=-\frac{1}{2} (-2)^{2} -2+1[/tex]
[tex]f(-2)=-\frac{1}{2} (4) -1[/tex]
4 can be rewritten as [tex]\frac{4}{1}[/tex] or [tex]\frac{8}{2}[/tex] so it has a common denominator.
[tex]f(-2)=-\frac{1}{2} * \frac{8}{2} -1[/tex]
[tex]f(-2)=-\frac{4}{2} -1[/tex]
[tex]f(-2)=-2-1[/tex]
[tex]f(-2)=-3[/tex]
If tanx =√24 and cosx =−2√23, find sinx.
Answer:
Step-by-step explanation:
sin(x)=cos(x) × tan(x)
=(-2√23)×(√24)
=(-2√23)×(2√6)
=(-4√138)
=(-4(2√(3×23)))
=(-8√69)
Solve for u: 2(u + 6) - 8 > 3(u - 5)
Answer:
19
Step-by-step explanation:
First get rid of the brackets:
[tex]2u + 12 - 8 > 3u - 15[/tex]
Then simplify:
[tex]2u + 4 > 3u - 15[/tex]
Get all the u's on one side:
[tex]2u - 3u > - 15 - 4[/tex]
Simplify and find u:
[tex] - u > - 19[/tex]
[tex]u < 19[/tex]

Answer:
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
Answer:
Step-by-step explanation:
c = 0.5t + 2
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20
c = 0.5(30) + 2 ⇒ c = 17
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36

What are the values of x and y in the following system of equations?
[tex]x+y=15[/tex]
[tex]y-x=5[/tex]
Step-by-step explanation:
By elimination method,
x+y=15
-x+y=5
------------
2y=20
i.e y=10
Now,
x+y=15
or, x+10=15
or, x=5
A robot can complete 8 tasks in
3 and a fourth hour. Each task takes the same amount of time.
Answer:
5/6 hour = 5/6 × 60 = 300/6 = 50 minutes
8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes
a. robot completes task in 6 1/4 minutes
b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6
robot can complete 9 tasks in one hour

What is the solve for r 9 = -3 -Зr?
Answer:
Hello the answer is - 4
Step-by-step explanation:
[tex]9 = - 3 - 3r \\ 9 + 3 = - 3r \\ - 3r = 12 \\ r = \frac{12}{ - 3} = - 4[/tex]
Answer:
-4
Step-by-step explanation:
-3r-3=9
9+3=-3r
12=-3r
12/-3=-3/-3r
-4=r
A barrel contained 70 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days.
At this rate, how many days did it take for all 70 gallons of water to leak out of the barrel?
Answer:
42 days
Step-by-step explanation:
Given
[tex]Gallons = 70[/tex]
Leakage = 5 gallons in 3 days
Required
Determine the number of days it finish leaking out
The scenario can be represented as:
5 gallons = 3 days
and
70 gallons = x
Where x represents the number of days to leak out 70 gallons
Cross Multiply:
[tex]5 * x = 3 * 70[/tex]
[tex]5 x = 210[/tex]
Divide both sides by 5
[tex]x = \frac{210}{5}[/tex]
[tex]x = 42[/tex]
Hence, it'll take 42 days
How you solved that
What are the solutions to the quadratic equation below? X^2-8x+16
(₋4)²
how i got it -
1st i used the sum-product pattern
x² - 8x + 16
x² -4-4+16
then, found the common fact from the two pairs
x² - 4 - 4 + 16
(-4) - 4(-4)
rewrite in factored form
(x-4)-4(-4)
(-4) (-4)
combine to a square
(-4) (-4)
Answer:
x=4*
Step-by-step explanation:
*THIS IS ASSUMING THAT THIS EQUATION IS EQUAL TO ZERO
X^2-8x+16=0
Let's solve this equation by factoring. First, we need to find factors of 16 that add to -8. We find that those factors are -4 and -4. X^2 is simply x times x.
Therefore, when it is factored It should look like this:
(x-4)(x-4)=0
Now we take both factors and set them equal to zero:
x-4=0; x-4=0
In both of these equations we just need to add 4 to both sides.
x=4; x=4
x=4

If LN = 6x - 5, LM = x + 7, and MN = 3x + 20, find MN
Answer:
68
Step-by-step explanation:
LM + MN = LN
x + 7 + 3x + 20 = 6x - 5
4x + 27 = 6x - 5
-4x -4x
27 = 2x - 5
+5 +5
32 = 2x
÷2 ÷2
16 = x
MN: 3x + 20
3(16) + 20
48 + 20

Given: ABCD is a parallelogram.
Prove: AB CD and BC DA
Angles Segments Triangles Statements Reasons
Please make the answer clear
Drawing the diagonal [tex]\overline {AC}[/tex] of the parallelogram makes the proof of the
congruency of opposite sides of a parallelogram clearer.
[tex]\overline {AB}[/tex] ≅ [tex]\overline {CD}[/tex] and [tex]\overline {BC}[/tex] ≅ [tex]\overline {DA}[/tex] by ASA rule of congruency
Reasons:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reasons
ABCD is a parallelogram [tex]{}[/tex] Given
∠BAC ≅ ∠DCA [tex]{}[/tex] Alternate interior angles theorem
∠BCA ≅ ∠DAC [tex]{}[/tex] Alternate interior angles theorem
[tex]\overline {AC}[/tex] ≅ [tex]\overline {AC}[/tex] [tex]{}[/tex] Reflexive property
ΔABC ≅ ΔACD [tex]{}[/tex] ASA rule of congruency
[tex]\overline {AB}[/tex] ≅ [tex]\overline {CD}[/tex] [tex]{}[/tex] CPCTC
[tex]\overline {BC}[/tex] ≅ [tex]\overline {DA}[/tex] [tex]{}[/tex] CPCTC
Therefore, segment [tex]\overline {AB}[/tex] and segment [tex]\overline {CB}[/tex] in ΔABC are congruent to
segment [tex]\overline {CD}[/tex] and segment [tex]\overline {DA}[/tex] in ΔACD by Angle-Side-Angle, ASA, rule of
congruency.
CPCTC stands for Congruent Part of Congruent Triangle are Congruent
