Luna mixes 3/4 cup of orange juice with 3/8 cup of cranberry juice. She gives 5/8 cup of the juice to mags. How much is left in lunas glass
Answers
Answer:
1/2
Step-by-step explanation:
3/4+3/8=9/8
9/8-5/8=1/2
Answer:
1/2 is left in Luna's glass
Step-by-step explanation:
3/4 is the same as 6/8
So 6/8 + 3/8 = 9/8
9/8 - 5/8 = 4/8.
4/8 can be simplified to 2/4, which can be simplified to 1/2

A 20-foot piece of wire is attached from the top of a flagpole to a stake in the ground 7 feet from the base of the pole. Find the height of the flagpole.
Answers
Answer:
18.73 feets
Step-by-step explanation:
Given that:
Horizontal distance between ground and foot of flagpole = 7 feets
Lenght of wire = 20 feets
The height of the flagpole, h can be obtained using Pythagoras :
Adjacent = sqrt( hypotenus² - opposite²)
Height of flagpole = sqrt((length of wire)² - (horizontal distance between ground and flagpole)²)
Let height of flagpole = h
h = sqrt(20² - 7²)
h = sqrt(400 - 49)
h = sqrt(351)
h = 18.73 feets
Please give me the answer nothing else
Answers
Answer:
h = 45.5 ÷ 7

On the first january 2014 carol invested some money in a bank account the account payes 2.5% compound interest per year on 1st jan 2015 carol withdrew £1000 from the account on 1st jan 2026 sge had £23517.60 in the account work out how much carol originally invested in the account
Answers
Answer:
$23,360
Step-by-step explanation:
Calculation to determine how much carol originally invested in the account
First step is to divide £23517.60 by 1.025
= (23,517.60)/(1+.025)
= (23,517.60)/1.025
=$22,944
Second step is to add back the $1,000 withdrew
=$22,944+$1,000
=$23,944
Now let calculate how much carol originally invested in the account
$23,944=1.025P
Divide both side by 1.025
P=$23,944/1.025
P=$23,360
Therefore the amount that carol originally invested in the account is $23,360

is searching online for airline tickets. Two weeks ago, the cost to fly from to was 250$. Now the cost is 330 $. What is the percent increase? What would be the percent increase if the airline charges an additional $50 baggage fee with the new ticket price?
Answers
Answer:
Cost increases to $330.
The percent increase here would be:
= (New price - Old price )/ Old price
= (330 - 250) / 250
= 0.32
= 32%
Cost increases to $330 and charges $50 baggage fee
= (New price - Old price )/ Old price
= (330 + 50 - 250) / 250
= 0.52
= 52%

If the following triangles are similar solve for x
Answers
Answer:
x = 16
Step-by-step explanation:
Given that ∆EFG ~ ∆ABC, therefore the ratio of the their corresponding sides would be equal.
Thus:
EG/AC = EF/AB
EG = 756
AC = (45x - 76)
EF = 1107
AB = 943
Plug in the values into the equation
756/(45x - 76) = 1107/943
Cross Multiply
756*943 = (45x - 76)*1107
712,908 = 49,815x - 84,132
712,908 + 84,132 = 49,815x
797,040 = 49,815x
797,040/49,815 = x
16 = x
x = 16

a² + b.
To solve this, we need to substitute the values of a & b in the given expresssion. So,
a² + b
= (-2)² + 5
