Answer:
a=1
Step-by-step explanation:
because 3/4 hour is 45 minute and it takes 4/4 distance to their grandparents hous ein 4/4 hour so 45÷3=15, 15×4=60 which is 1hour
The Answer is A: 1 hour
Step-by-step explanation:
since they can drive 3/4 the distance in 3/4 hours, they can also drive 1/2 the distance in 1/2 hours and so on. If they want to visit the grandparent's house, they need to drive 4/4 the distance which is equivalent to 1 so it will take 1 hour for them to go to the house at the same rate.
A Tip From Me To You:
sometimes the question tries to trick you to make you overthink it so don't overthink it, try to just solve it simply.

What is the value of y?
Answer:
y = 66
Step-by-step explanation:
Exterior angles thm:
y + y - 31 = y + 35
2y - 31 = y + 35
2y - y = 35 + 31
y = 66
To find the distance across the river, the given diagram is laid out. what is the distance rounded to the nearest meter?
Given:
Angle A = 18.6°
Angle B = 93°
Length of side AB = 646 meters
To find:
the distance across the river, distance between BC
Steps:
Since we know the measure of 2 angles of a triangle we can find the measure of the third angle.
18.6° + 93° + ∠C = 180°
111.6° + ∠C = 180°
∠C = 180° - 111.6°
∠C = 68.4°
Therefore the measure of angle C is 68.4°.
now we can use the law of Sines,
[tex]\frac{BC}{sinA}=\frac{AB}{SinC}[/tex]
[tex]\frac{BC}{sin(18.6)}= \frac{646}{sin(68.4)}[/tex]
[tex]BC[sin(68.4)] = 646 [sin(18.6)][/tex]
[tex]BC = \frac{646*sin(18.6)}{sin(68.4)}[/tex]
[tex]BC = \frac{646 * 0.3190}{0.9298}[/tex]
[tex]BC = 221.63[/tex]
[tex]BC = 222[/tex] meters
Therefore, the distance across the river is 222 meters.

Probability of picking 2 marbles without looking out of a bag containing 2 red marbles, 2 blue marbles, and 2 white marbles. What is the probability that you will choose a red marble and then a blue marble without replacing the red one?
Answer: 2/15
Step-by-step explanation:
2 red
2 blue
2 white
6 total
2/6 chance of getting red (1/3)
2/5 chance of getting blue next
2/5*1/3 = 2/15

In a state assembly, 35% of the legislators are Democrats, and the other 65% are Republicans. 70% of the Democrats favor raising sales tax, while only 40% of the Republicans favor the increase. If a legislator is selected at random from this group, what is the probability that they favor raising sales tax? Give your answer as a percentage rounded to the nearest tenth.
Answer:
Probability of selecting a legislator who favors rising sales tax is 0.63
Step-by-step explanation:
Given
Percentage of legislators that are democrats = 0.35
Percentage of legislators that are Republicans = 0.70
All the democrats favor raise in sales tax , so their probability is 1
and only 40% of the Republicans favor raise in sales tax.
Probability of selecting a legislator who favors rising sales tax is
(0.35*1)+(0.70*0.40)
= 0.63

Find the value of YZ
Answer:
YZ = 44
Step-by-step explanation:
Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:
WA * AX = ZA * AY
We can substitute the values we are given to get:
(2x - 6)(21) = (x + 1)(30)
42x - 126 = 30x + 30
12x - 126 = 30
12x = 156
x = 13
Using segment addition postulate, we can say that:
YZ = YA + AZ
And we can plug in what we know from the diagram:
YZ = 30 + x + 1
We can also plug in the value of x, 13
YZ = 30 + 13 + 1 = 44

A right cone has a slant height of 7 and a radius of 5. What is its surface
area?
O A. 357 units
B. 120 x units2
O c. 25x units2
D. 60 units
Answer:
D
Step-by-step explanation:
D. 60 Units
The surface area of the right cone is,
⇒ SA = 60π units²
What is mean by Multiplication?The multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
We have to given that;
Radius of cone (r) = 5 units
Slant height of cone (l) = 7 units
Now, We know that;
The formula that is used to calculate the surface area of a cone is;
⇒ SA = πrl + πr²
Hence, We can substitute all the values we get;
⇒ SA = πrl + πr²
⇒ SA = π × 5 × 7 + π × (5)²
⇒ SA = 35π + 25π
⇒ SA = 60π units²
Thus, The surface area of the right cone is,
⇒ SA = 60π units²

Amy has a jar of jelly beans. In the jar there are 14 red jelly beans, 22 blue jelly beans, 12 yellow jelly beans, and 8 green jelly beans. What is the probability that amy will randomly select a red jelly, eat it, and then select a green jelly bean?
Answer: G
Step-by-step explanation:
probability of picking a red jelly first = 14/56 or 1/4
probability of picking a green jelly next = 8/55
1/4*8/55 = 2/55

Given is the cyclic quadrilateral.
Opposite angles of cyclic quadrilateral are supplementary:
m∠U + m∠W = 18014 + 4x + 6x - 14 = 18010x = 180x = 18m∠V + m∠T = 18015y - 4 + 12y - 5 = 18027y = 189y = 189/27y = 7U and w are opposing so supplementary

15y-4+12y-5=18027y-9=18027y=189y=7Ayoub is driving to France for his holiday.
He will drive a total distance of 300 miles. Ayoub sets off at 07:15.
It takes him 2.5 hours to travel the first 125 miles.
Use this information to estimate the time Ayoub will arrive.
Answer:
10:30 hours
Step-by-step explanation:
Total distance=300 Miles, Start Time=07:15
Distance travelled so far is 125 miles for 2.5 hours
First we need to calculate Ayoub's speed as follows
Speed=Distance/Time
=125miles/2.5hour
=50 miles/hr
The calculate the remaining distance
=300-125
=175 Miles
Assuming that Ayoub Travels in the same speed at the first 300 miles, the time he will use to cover the remaining 175 miles is
Time=Distance/speed
Substituting the values
Time=175/50
=3.5 hours
The time he will arrive at Paris is
07:15+03:30
=10:30 hours

Question 2
First calculate the time taken to travel from woodpine to Westray
Time=Distance/ Speed
=32.5/65
=0.5 hours or 30 minutes
Next we calculate the average speed
Average speed is calculated by taking the total distance divided by total time taken
Total distance =32.5+100
=132.5KM
Total time=2+0.5
Average speed=132.5/2.5
=53km/
