The area of a circle, in terms of π, is 196π m2.
Find the value of the radius.
Step-by-step explanation:
if area of circle = pi times radius^2,
area of circle divided by pi = radius^2
so, square root (area of circle divided by 2) = radius.
so, 196pi = m2
approx 616
616=m2
sqrt 616 =m
approx value of radius is 25 or 24.8

What is the rectangular form of 17(cos(315°) + isin(315°))?
The value of the expression 17[cos(315°) + isin(315°)] will be (17√2 / 2) – (17√2 / 2)i. Then the correct option is A.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The rectangular form of 17(cos(315°) + isin(315°)).
We know that the value of cos 315° and sin 315°.
[tex]\sin 315^o = \dfrac{-1}{\sqrt2}\\\cos 315^o = \dfrac{1}{\sqrt2}[/tex]
Then the value of the expression will be
⇒ 17[(1/√2) – (1/√2)i]
⇒ (17√2 / 2) – (17√2 / 2)i
Then the correct option is A.

There were 7,313 more searches in the library book checkout system in January than February. In February there were 8,972 searches, how many searches were done in both months?
Given:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February.
To find:
The searches in both months.
Solution:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February. So,
Searches in January = 8972 + 7313 = 16285
Now,
Total number of Searches in both months = January + February searches
[tex]=16285 + 8972[/tex]
[tex]=25257[/tex]
Therefore, total number of searches in both months is 25257.

Paola and Tom opened a lemonade stand. This week they sold 20 cups of lemonade and received $5 in tips. If they spend $30 on supplies, which inequality could be used to find x, the price of each cup they must sell to make a profit?
Answer:
20x + 5 < 30
Step-by-step explanation:
To make a profit, the price on supplies must be less than the amount at which they sold their wares
Since they received $5 in tip, the amount of profit left to be accounted for is 30-5 = 25
So now, we need the smallest price at which they will sell per lemonade to make a profit
Mathematically, that will be;
20x + 5 > 30
Using this inequality X they will know the value of x that will give them profit

A number divided by 42 has a quotient of 28 with a remainder of 4. What is the number?
O 1,064
o 1,172
O 1,176
O 1,180
Answer:
D. 1,180
Step-by-step explanation:
Given the following data;
Divisor = 42
Quotient = 28
Remainder = 4
A quotient of 28 simply means that a number divided by 42 would have a value that is equal to 28 without any remainder.
Let the unknown number be X
X = (42*28) + 4
X = 1176 + 4
X = 1180.
Method II
Y/42 = 28
Cross-multiplying, we have;
Y = 28 * 42
Y = 1176
Given that the remainder is 4
X = Y + 4
X = 1176 + 4
X = 1180.
Therefore, the number is 1180.

One tree can produce 175 avocados. The avocados are packed in boxes of 24. How many boxes are needed?
Answer:
8 boxes
Step-by-step explanation:
Divide 175 by 24 since you have 175 avocados and 24 can be put in each box. This gives you 7.29166666667. You have to round up to get 8.
Answer:
8 boxes would be needed
Step-by-step explanation:
175/24 = 7 with a remainder of 7 and you cannot just leave out those 7 avocados, they will be lonely so therefor you will need another box and 7+1=8

Laura buys a saddle in the UK for £850 Delivery is free. Steve buys the same saddle from Holland for 990 Euros. He pays 15 Euros for delivery. £1 = 1.18 Euros Including the delivery charge, whose saddle is cheaper?
Answer:
Laura's saddle is cheaperStep-by-step explanation:
We want to convert from euros to pound and compare which purchase is more expensive.
given data
we are told that Steve buys the same saddle from Holland for 990 Euros
given the exchange rate in pounds, it will be
£1 = 1.18 Euros
x=990 Euros
cross multiply we have
x=990/1.18
x= £838.98
Steve buys at £838.98
delivery charge is 15 Euros to pounds
£1 = 1.18 Euros
x=15 Euros
cross multiply we have
x=15/1.18
x= £13.04
to expenses incurred by Steve= £838.98+£13.04
=£852.02
Laura's saddle is cheaper

Determine the intercepts of the line.
x-intercept:( , )
y-intercept:( , )
Answer:
x-intercept: (-7,0)
y-intercept: (0,2)
Step-by-step explanation:
The x-intercept is (-7,0) because on the graph we can see that the line lies on the x-axis on the point (-7,0).
The y-intercept is (0,2) because we can see that the line pass through the y-axis on the (0,2) point.
