In the diagram of circle M shown, the measure of major arc PRQ=268 . Which of the following
is the measure of angle PRQ ?
Step-by-step explanation:
The Answer is 46
The measure of Arc PRQ is 268. Another part of the arc is PQ. PRQ+PQ forms a full circle In which a circle has 360 degrees. Using that
[tex]268 + x = 360[/tex]
[tex]x = 92[/tex]
Since we are asked to the measure of PRQ and it is inscribed in arc PQ. It is half of PQ so the answer is
[tex]92 \div 2[/tex]
which is 46.

Olivia does chores every Saturday morning. She spends of her time cleaning her room. Of the remaining of her time, she spends of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?
Answer:
4/7 of her total time cleaning the kitchen
Step-by-step explanation:
Olivia does chores every Saturday morning. She spends 1/3 of her time cleaning her room. Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?]
Let
x = her total time
Room cleaning = 1/3x
Time remaining = 2/3x
Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen.
Kitchen cleaning = 6/7 of 2/3x
= 6/7 * 2/3x
= (6*2)x/(7*3)
= 12/21x
= 4/7x
Olivia spent 4/7 of her total time cleaning the kitchen
Which is the sum of the first 6 terms of the geometric series?
7+21 +63
Answer:
2,548
Step-by-step explanation:
First, we have to find out the rule. The rule is multiply the previous number by 3 to get the next number.
7x3=21
21x3=63
So, we would continue this pattern until we have the first 6 numbers which are 189, 567, and 1701.
The questions is asking for the SUM of the 6 numbers so you would add the those numbers and do this equation:
7+21+63+189+567+1701= 2548
Hope this helps! :)
How do i solve for this?
9514 1404 393
Answer:
97.42 square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.
75° = (75°)×(π/180°) radians = (5/12)π radians
Then the area is ...
A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units
__
Equivalently, you can find the area of the circle in the usual way:
A = πr² = π(12.2²) ≈ 467.59465
Then, multiply by the fraction of the circle that is shaded (75°/360°)
sector area = (467.59465)(75/360) = 94.42 . . . square units
The student council at Oxford High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $130. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be?
Answer:
Number of shirts to breakeven = 65 shirtsCost of breakeven shirts = $650Step-by-step explanation:
First find the profit they will make from each shirt:
= Selling price - Cost price
= 12 - 10
= $2
They need to cover the cost of setting up which is $130. The number of shirts to sell given a profit of $2 from each shirt is:
= 130 / 2
=65 shirts
Cost of selling 65 shirts:
= 65 * 10 per shirt
= $650
Find the perimeter of the triangle whose vertices are the following specified points in the plane.
(5,6), (4,1) and (-4,2)
Answer:
23 units
Step-by-step explanation:
Let the vertices of the triangle be A(5,6), B(4,1) and C(-4,2)
Perimeter of the triangle = AB + AC + BC
AB = √(5-4)²+(6-1)²
AB = √1²+5²
AB = √1+25
AB = √26
For BC where B(4,1) and C(-4,2)
BC = √(4-+4)²+(1-2)²
BC = √8²+1²
BC = √64+1
BC = √65
For AC where A(5,6) and C(-4,2)
AC = √(5+4)²+(6-2)²
AC = √9²+4²
AC = √81+16
AC = √97
Perimeter = √97 + √26 + √65
Perimeter = 9.85+5.09+8.06
Perimeter = 23
Hence the perimeter of the triangle is approx 23 units

The ratio of the length to the width of the rectangle is 10:6. Of the perimeter of the rectangle is 160 meters, find the measure of the width. Show your work
Answer:
60 meters, see explanation.
Step-by-step explanation:
We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.
You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.

Mark reduce the size of a photo to a height of 4 inches. What is the new width if it was originally 16 inches tall and 8 inches wide?
Answer:
Step-by-step explanation:
new height is ¼ of original height
new width = ¼×8 = 2 inches
Answer:
2 inches
Step-by-step explanation:
To find the new width, find the scale factor that was used to reduce the photo.
Since 16 divided by 4 is 4, 4 is the scale factor.
To find the new width, divide 8 by 4:
8/4
= 2
So, the new width is 2 inches
ayo so like i'm doing logarithms and i need help how do you solve 3(5)^x=192 for the variable thanks
Answer:
Exact Form:
x = ln ( 64 )/ ln ( 5 )
Decimal Form:
x = 2.58405934 …
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
Start by dividing both sides by 3
5^x = 192/3
5^x = 64
Now take the log of both sides
log(5^x) = log(64)
Bring down the power
x log(5) = log(64)
Find the logs

4. y = 8(1) - 5= 8 - 5 = 3
y = 8(2) - 5 = 16 - 5 = 11
y = 8(5) - 5 = 40 - 5 = 35
y = 8(0) - 5 = 0 - 5 = -5
y = 8(-1) - 5 = -8 - 5 = -13
[tex]10x + 6 = 8x[/tex]
[tex]6 = 8x - 10x[/tex]
[tex]6 = - 2x[/tex]

When [tex] x = 2, y = \bold{ 11} [/tex]
[tex]y = (8 \times 2)- 5[/tex]
[tex]y = 16 - 5[/tex]

what is the interest on RS. 1000 at 10 p.c.p.a for 1 year.
Answer:
Interest wil be 10% of 100 which is 10
So, interest will be Rs.10
And total amount to be payed will be 100+10 which is Rs.110
Answer:
Interest= Rs. 10
Step-by-step explanation:
Interest of Rs.100 on 10 p.c.p.a is 10% of 100
i.e., 100*10/100 = 10
Thus we have 10 as the interest

I KNOW PART A BUT IM REALLY STUCK ON PART B PLS HELP!!
Part A:
I got the number of kids in the survey which is 130 and I found 70 which is the amount of kids who like playing on a pc/console. I took 130 and 70 and converted it into a fraction 70/130, I simplified it to 7/13 and used a calculator to get my percentage which I rounded and got 53%
Part B:
I drew a table and just focused on column two. I looked at how many people don't like phone or pc and I found that 10 is how many people like phone and not pc, 30 is people who dont like phone or pc, together its 40, so you need to find what the percentage 30 is of 40, or 3/4, I used a calculator and converted it into a percentage and I got 75%

Step-by-step explanation:
1.) -4x+35 > 2 (Move the constant to the right-hand scale side and change its sign)
-4x > 2 - 35
2.) -4x > 2 - 35 (Calculate the difference)
4x > -33
3.) -4x > -33 (Divide both sides of the inequality by -4 and flip the inequality sign)
x < 33/4
