cups
Answer:
number of cups of lemonade used = 1/3 cups
Step-by-step explanation:
number of cups of lemonade : strawberry juice
= 1 : 3
Enter the number of cups of lemonade used for 1 cup of strawberry juice.
Let
x = number of cups of lemonade used
number of cups of lemonade : strawberry juice
= x : 1
Equate both ratios to get x
1 : 3 = x : 1
1/3 = x / 1
Cross product
1*1 = 3 * x
1 = 3x
Divide both sides by 3
x = 1/3 cu
number of cups of lemonade used = 1/3 cups

Andy drove from his home to his sisters house he stayed at her house and then drove back home. please help ASAP
Answer:
a) 45 minutes
b) 100 km/hr
Step-by-step explanation:
a) It is the length of the horizontal line in the graph. It extends from 14:45 to 15:30 and that is 45 minutes.
b) Andy travels 50 km in 30 minutes (=0.5 hr), that's 50/0.5 = 100 km/hr.
As per linear equation, Andy stayed his sisters house for 45 minutes.
The average speed on his journey home is 100 km/hour.
What is a linear equation?"An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line."
As per the graph, Andy drove from his home to his sisters house.
Then he rested for a while there.
After that, he returned back to his home.
It is clear from the graph that, Andy stayed his sisters house
= (15:30 - 14:45) hours = 45 minutes
Again, from the graph, the distance between Andy and his sister's house is 50 k.m.
Andy return back to his home in
(16:00 - 15:30) hours
= 30 minutes
= 0.5 hours
Therefore, the average speed on his journey home is
[tex]= \frac{50}{0.5} km/hour\\= 100 km/hour[/tex]

Alia made a scale drawing of a square park, which has a side length of 30 feet. She used the scale 3 centimeter = 5 feet. What will be the area of the scale drawing?
Answer:
324cm²Step-by-step explanation:
Given the scale conversion;
3 centimeter = 5 feet
x = 30 feet
Cross multiply
5x = 3 * 30
5x = 90
x = 90/5
x = 18cm
Hence the side length in cm is 18cm
Area of the square = L²
Area of the square = 18²
Area of the square = 324cm²
Hence the area of the scale drawing is 324cm²
Nat is thinking of a four-digit counting number. The thousands digit and the hundreds digit are the same. The sum of all 4 digits is 28. The four-digit number is an odd multiple of 5. Exactly two digits are even. What is Nat’s number?
We want to use the given information to find a 4-digit number.
We will get the number: 8,875
----------------------------
A general 4-digit number can be written as:
a*1,000 + b*100 + c*10 + d
Where a, b, c, and d are whole numbers between [0, 9].
We also know that:
"The thousands digit (a) and the hundreds digit (b) are the same"
a = b.
"The sum of all 4 digits is 28"
a + b + c + d = 28
"The 4-digit number is an odd multiple of 5"
All the multiples of 5 end with a 0 or a 5, this is an odd one, so it must end with a 5, then we know that:
d = 5
"Two of the digits are even".
Ok, now let's write the equations that we found
a = b
a + b + c + d = 28
d = 5
Because of the last statement, only two digits are even, and we have that a is equal to b, the two even numbers must be these two, then we know that:
a is even.
And from the first equation, we can rewrite the second one as:
a + a + c + d = 28
Using the third equation and replacing it here, we have:
a + a + c + 5 = 28
2*a + c = 23
Now we can try to input different values of a in the equation, and see what value of c we get:
if a = 2, then:
2*2 + c = 23
4 + c = 23
c = 23 - 4 = 19
But c can be, at max, 9, then we can discard this.
Now let's try with a larger value for a, this time a = 8.
2*8 + c = 23
16 + c = 23
c = 23 - 16 = 7
c = 7
This is correct, then we can conclude that:
a = 8b = 8c = 7d = 5Then the 4-digit number is:
8,875
