Assume that y varies directly with x. If y = 2/5 when
x= 1/3, find y when x = 1/4. Enter in any fractions using
a/ (e.g. "1/2" is the same as ?).
Answer:
y = 3/10
Step-by-step explanation:
(1/3) / (2/5) = (1/4) / y
y = (1/4) (2/5) / (1/3) = (2/20) / (1/3) = 3/10
check: (1/3) / (1/4) = 4/3
(2/5) / (3/10) = 20/15 = 4/3

A spinner is evenly divided into eight sections: three are red, three are white and two are green. If the spinner is spun twice, then the probability of getting the same color twice is
Answer:
11/32
Step-by-step explanation:
Given that:
Red section (R) = 3 ; white section (W) = 3 ; green section (G) = 2
Total Number of sections = 8
Probability of getting the same color on two spins :
Probability = (required outcome / Total possible outcomes)
Either P(RR) or P(WW) or P(GG)
(3/8 * 3/8) + (3/8 * 3/8) + (2/8 * 2/8)
9/64 + 9/64 + 4/64
(9 + 9 + 4) / 64
22 / 64
= 11/32
the probability of getting the same color twice is
[tex]\frac{11}{32}[/tex]
Given :
A spinner is evenly divided into eight sections: three are red, three are white and two are green.
Total of 8 sections.
red=3
white =3
green =2
Probability of getting two red color =[tex]\frac{3}{8} \cdot \frac{3}{8}= \frac{9}{64}[/tex]
Probability of getting two white colors =[tex]\frac{3}{8} \cdot \frac{3}{8}= \frac{9}{64}[/tex]

It takes 3 hours 15 minutes to fly from ato b at constant speed.Find howlong the journdy takes if(a) the speed is3÷2 times that of the original speed (b) if the speed is three_quarters of the original speed.
Answer:
For 3/2 of the speed = 292.5 minutes
For 3/4 of the speed = 146.25 minutes
Step-by-step explanation:
It takes 3hrs 15 minutes to fly from A to B
From A to B = 180minutes + 15 minutes
= 195 minutes (At constant speed)
At constant speed,
If the speed is 3/2 of the original speed,
It will be,
3/2 X (195 minutes) = 585 / 2 = 292.5 minutes
On the other-hand,
If the speed is 3/4 of the original speed,
3/4 X (195 minutes) = 585 / 4 = 146.25 minutes

Answer:
x = 9 cm
Step-by-step explanation:
The formula for the surface area of a cylinder can be written as ...
SA = 2πr(r +h) . . . . . where r is half the diameter, and h is the height
For the given cylinder, we have ...
972π cm² = 2π(x)(x+5x) = 12πx²
Dividing by 12π gives ...
81 cm² = x²
Taking the square root, we have ...
9 cm = x

A different building has office space for rent that doesn't not require a one time fee, but you must pay rent of $1000 per month. If you have $15000, at which building can you rent office space for the greatest amount of time
Answer: First building at 17.5 months
Step-by-step explanation:
Months you can stay in the first building.
One time fee of $1,000 reduces the amount you have to;
= 15,000 - 1,000
= $14,000
Rent is $800. Months you can stay;
= 14,000/800
= 17.5 months
Months you can stay in second building;
Rent is $1,000 and no one time fee;
= 15,000/1,000
= 15 months
You can stay longer in the first building for 17.5 months.

PQ = 11 feet. QR = 7 feet, and PR = 15 feet. Which lists the angles in measures order from smallest to largest?
A. P. R. Q.
B. R. Q. P.
C. P. Q, R
D. Q. R, P
A B C or D?
Answer:
A: P, R, Q
Step-by-step explanation:
Because since PQ = 11, then you have to put an arrow across from that side with is angle R and that's Middle. QR = 7, which you have to put an across from that side with is angle P, and that's smallest. PR = 15, which you have to put an arrow across from that side which is angle Q, and that's the largest. Now put everything in order from the angles smallest to largest like this,
P, R, Q.
Hope this helps :)
The angles in measures order from smallest to largest is <P, <Q and <R.
What is Triangle property?If two triangle angles are not equal, the lengths of the sides that face them are also not equal, with the longer side facing the larger angle.
Given:
PQ = 11 feet. QR = 7 feet, and PR = 15 feet.
The Largest side is PR = 15 feet.
So, the angle opposite to largest side is also largest, i.e., <R is largest.
and, smallest side is QR = 7 feet,
So, the angle opposite to smallest side is also smallest, i.e., <P is smallest.
Hence, angles in measures order from smallest to largest is <P, <Q and <R.

If the number you're dividing by has a decimal, move the decimal point all the way to the right counting the number of places you've moved it to. Then move the decimal point in the number you're dividing the same number of places to the right.
Insert a decimal point in the quotient (answer) space, exactly above the decimal point in the number under the division bar.
Divide until the remainder is zero, or until you have enough decimal places in your answer. You can also stop if the remainder repeats because this indicates that your answer is a repeating decimal.

Daniela is saving her babysitting money to buy a bicycle that costs $290. The first week, she saved $66, and the second week she saved $113. Use the diagram to find b, the amount of money Daniela still needs to save for a bike. $290 $113 $66
Answer:
b = 111
Step-by-step explanation:
66 + 113 = 179
So in order to have a total of $290, you need about $111 more dollars.
270 - 179 = 111
So the final answer is 111.
Answer:
$111
Step-by-step explanation:
Cost of the bicycle=$290
total saved= $66 + $113
=$179
b = $290 - $179
=$111
