Karla will walk her bike at a speed of 6 mile/hour from her house to the bike
shop, which is 2.5 mi from her house, to get the bike fixed. She expects to
wait 30 min for the repair. Then she will return home by riding her bike at a
speed of 15 miles/hour. How long will the entire trip last? *
A. 1.30 hours
B. 1.50 hours
C. 0.50 hour
D. 1.08 hours
Answer:
D. 1.08 hours
Step-by-step explanation:
Speed = distance / time
Going to the bike shop
speed = 6 mile/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
6 = 2.5 / t
Cross product
6t = 2.5
Divide both sides by 6
t = 2.5/6
= 0.417 hour
She waited for 30 minutes for the repair, that is 0.5 hour
Going back home
Speed = 15 miles/hour
Distance = 2.5 mi
Time = t
Speed = distance / time
15 = 2.5 / t
Cross product
15t = 2.5
Divide both sides by 15
t = 2.5 / 15
= 0.167 hour
Total time of the entire trip =
0.417 hour + 0.5 hour + 0.167 hour
= 1.084 hour
Approximately 1.08 hour
The correct answer is D. 1.08 hours
5x +7 y=-17
4x – 3y = -5
Substitute.
Answer:
(x,y) = (-2, -1)
Step-by-step explanation:
We start off by substituting the value of "x".
5x+7y=-17
x=-[tex]\frac{5}{4} + \frac{3}{4}y[/tex]
We then solve 5[tex]5(-\frac{5}{4}+\frac{3}{4}y ) +7y= -17[/tex]
y=-1 *Substitute the value of "y"
x= -[tex]-\frac{5}{4}+\frac{3}{4}x(-1)[/tex]
x=-2
[tex]\left \{ {{-17=-17} \atop {-5=-5}} \right.[/tex] This works.
Seven more than twice a number is 7
Answer:
0
Step-by-step explanation:
0 × , or 0² is 0, and 0 + 7 is 7. Hope this helps!
Can someone help me solve this fast??
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
[tex]\sqrt{3x+8}=\sqrt{4x+1}[/tex]
Square both sides:
[tex](\sqrt{3x+8})^{2} =(\sqrt{4x+1})^{2}[/tex]
[tex]3x+8=4x+1[/tex]
Subtract 8 from both sides:
[tex]3x+8-8=4x+1-8[/tex]
[tex]3x=4x-7[/tex]
Subtract 4x from both sides:
[tex]3x-4x=4x-7-4x[/tex]
[tex]-x=-7[/tex]
Divide both sides by -1:
[tex]\frac{-x}{-1}=\frac{-7}{-1}[/tex]
[tex]x=7[/tex]
A water polo team threw a pizza party after winning the championship. They needed enough
pizza for 52 people. Each pizza serves 4 people and costs $12. How much did the pizza cost
all together?
Answer:
156
Step-by-step explanation:
52÷4= 13
this means you need 13 pizzas
each pizza costs 12 dollars so to work out the total cost for 52 people you multiply 13 by 12
13×12=156
Answer:
$156
Step-by-step explanation:
52 ÷ 4 = 13
13 × 12 = $156

for a certain online store, the distribution of number per hour is approximately normal with mean 1200 purchases and standard deviation 200 purchases. for what proportion of hours will the number of purchases at the online store exceed 1400?
a)5%
b)68%
c)16%
d)32%
Answer: 16%
Step-by-step explanation:
When we have a normal distribution, the 100% of our sample will be placed in a "gaussian bell".
Where the middle of this bell coincides with the mean.
The mean, in this case, is 1200, and the standard deviation is 200.
In the image below you can see that between the points.
Mean + standard deviation and the end of the graph, we have:
13.5% + 2.35% + 0.15% = 16%
And particularly, if we want to know the percentage that exceed 1400, will be the same percentage above the mean plus the standard deviation.
mean = 1200
SD = 200
mean + standard deviation = 1200 + 200 = 1400.
Then the percentage that exceeds 1400 is equal to the percentage that we found above, then the correct option is C: 16%

Juanita is converting 7 meters to inches. Will the number of inches be less than or greater than 7? choose one of these answers below
The number of inches will be less than 7 because 7 is a small number.
The number of inches will be greater than 7 because 7 is a small number.
The number of inches will be less than 7 because inches are smaller than meters.
The number of inches will be greater than 7 because inches are smaller than meters.
Answer:
The number of inches will be greater than 7 because inches are smaller than meters.
Step-by-step explanation:
Step-by-step explanation:
1 inch is around 2.54cm, which is a lot less than 1 meter.
Since inches are a smaller unit than meters, the number of inches will be greater than 7 to have the same equivalent length.
"The number of inches will be greater than 7 because inches are smaller than meters" is correct.

Consider the these two linear equations:
10x + 5y = 90
y = ax + 18
What value of a will make the two lines parallel?
Answer:
a = -2
Step-by-step explanation:
The first equation can be rewritten in slope-intercept form:
5y = -10x +90
y = -2x +18
The value a=-2 will make the second line identical to the first.

10x-3=-5x-18
(10x-3=15x-18)
X = -1
Hey there!
[tex]Answer:\boxed{x=-1}[/tex]
[tex]Explanation:[/tex]
10x - 3 = -5x - 18
10x - 3 + 5x = -5x - 18 + 5x Add 5x to both sides
15 - 3 = -18
15x - 3 + 3 = -18 + 3 Add 3 to both sides
15x = -15
15x/15 = -15/15
x = -1

The m∠P is three less than twice the measure of ∠Q. If ∠P and ∠Q are supplementary angles, find the measures of both angles.
Answer:
m∠P =119
m∠Q = 61
Step-by-step explanation:
m∠P = 2(∠Q)-3 or p=2(q)-3
supplementary angles so they combine to equal 180!
soooooo we can take
q+p=180
input what p equals and you get
q+ 2(q)-3=180
3q-3=180
3q=183
q=61
now we have what m∠Q is, so just subtract that from 180 to get m∠P
180-61=119
