Answer:
2.4 Litres of waterStep-by-step explanation:
80% of (3 litres)
You can take 3 litres to be 3000 ml which is how I solved it.
OPTION 1_________80/100 x 3000
=2400 or 2.4 litres
The same can go with not taking ml which you can just use litres
OPTION 2_________80/100 x 3
=2.4 litres
I used the ml since I do not need the calculator for that one and it is faster to calculate.

In the morning Josh completed a hike on a 5/14 mile trail. In the afternoon he completed a hike on a second trail using his pedometer to keep track of the miles. The pedometer measured 3.35 miles for the second trail. What is the total number of miles Josh hiked? Enter your answer as a decimal to the nearest tenth.
Answer:
Total distance travel = 8.60 miles
Step-by-step explanation:
Given:
Distance of 1st trail = [tex]5\frac{1}{4}[/tex] miles = 5.25 miles
Distance of 2nd trail = 3.35 miles
Find:
Total distance travel
Computation:
Total distance travel = Distance of 1st trail + Distance of 2nd trail
Total distance travel = 5.25 + 3.35
Total distance travel = 8.60 miles

Given m
11
n, find the value of x and y.
(9x+1)
m
jo
(7x+13)
n
Answer:
x = 6
y° = 125°
Step-by-step explanation:
9x + 1 and 7x + 13 are alternate angles and has same measurement
9x + 1 = 7x + 13
9x - 7x = 13 - 1
2x = 12
x = 6
y° and 7x + 13 are supplementary angles so their sum is 180°
7x + 13 ➡ 7×6 + 13 = 55°
55 + y° = 180 subtract 55 from both sides
y° = 125°
Marisha wants to measure the volume of a rock. She pours water into a graduated cylinder and it measures 200 mL. Then she drops the rock in it, and measures the water level at 297.5 mL. The volume of the rock is the difference between the water level before and after. What is the volume of the rock
Answer:Volume of Rock= 97.5ml
Step-by-step explanation:
STEP 1
Finding the volume of rock using the graduated cylinder that measures volume of liquid can be done by determining how much water is being displaced by the rock after submersion.
Step 2
Volume of water before adding rock = 200mL
Volume of water after adding the rock = 297.5mL
Volume of rock =Volume of water after adding the rock - Volume of water before adding rock
Volume of Rock = 297.5-ml 200ml
= 97.5ml

passes through (-2,-2) and is parallel to the line 5x-y=45x
The equation of the line is y + 40x = -78.
Here, we are given that a line passes through point (-2,-2) and is parallel to the line 5x - y = 45x.
when two lines are parallel their slopes are equal. So, let us first find the slope of line 5x - y = 45x.
The standard form of the equation of a line is- y = mx + c, where m is the slope of the line.
Here 5x - y = 45x can be written as-
y = -40x
Thus, the slope of the line is -40.
Now we can use the point slope form to find the equation of our line.
According to the point slope form-
(y - y1) = m(x - x1)
here, x1 = -2 and y1 = -2
Thus equation becomes-
(y + 2) = -40 ( x + 2)
y + 2 = -40x - 80
y + 40x = -78
Thus, the equation of the line is y + 40x = -78

YA is an altitude of AXYZ. What is the length of YA?
O 5√3 units
O 10√3 units
O 15 units
O 20 units
By using Pythagoras theorem we can calculate length of YA and which will come out as, 5√3 units, So Option A is correct.
What is Pythagoras theorem?It is the most important theorem of mathematics, which tells us the relationship between sides of the right angle triangle, which are known as Base(A), Height(B), Hypotenuse(H).
Pythagoras theorem,
H² = A² + B²
Given information,
The length of the side YZ is twice of the side AZ,
Given length of side YZ is, 10 unit
Therefore, length of side AZ is, 5 unit
YA is altitude of ΔXYZ,
and ΔAYZ is a right angle triangle so we use Pythagoras theorem
YZ = H = 10
ZA = A = 5
YA = B = ?
100² = 5² + B²
B = 5√3
Hence, the length of side YA is 5√3 unit

Step-by-step explanation:
Samuel and Savannah purchase stocks in a company. Samuel started with 50 shares and of the stock and buys 10 shares per month. Savannah did not start with any shares, but she buys 25 shares per month. Write an equation that represents the number of months it will take before Savannah and Share the same amount of shares
Answer:
50 + 10m = 25m
Step-by-step explanation:
Given that:
Samuel:
Stating shares = 50 shares plus 10 shares per month
Savanah :
Starting shares = 0 plus 25 shares per month
Let number of months = m
Samuel shares = savanna shares
50 + 10m = 25m
50 = 25m - 10m
50 = 15m
50 / 15 = m

Write the simplest polynomial function with the given roots 1/2,5, and -2
Answer:
x³-7x²/2-39x/2 + 10Step-by-step explanation:
Given 1/2,5, and -2 as roots of the polynomial, the function in terms of x is expressed as;
P(x) = (x - 1/2)(x - 5)(x+2)
Expand;
(x - 1/2)(x - 5) = x²-5x -x/2 + 5/2
(x - 1/2)(x - 5) = x²-11x/2 + 5/2
P(x) = (x²-11x/2 + 5/2)(x+2) = x³+2x²-11x²/2-22x+5x/2 + 10
P(x) = x³-7x²/2-39x/2 + 10
Hence the required polynomial is x³-7x²/2-39x/2 + 10
If John deposits $525 in a savings account and his account pays an annual interest rate of 5.5% and makes no other deposits and withdrawals what is the simple interest earned for 5 years , 5 months , and 5 days
Answer:
The amount of simple interest earned is $156.79
Step-by-step explanation:
Mathematically;
Simple interest = PRT/100
From the question;
P = $525
R = 5.5%
T ; to get this, we need to make the numbers agree;
We do this by dividing number of months by 12 and number of days by 365
So 5 years, 5 months and 5 days will be;
5 + 5/12 + 5/365 = 5.43
So, using this in the simple interest calculations, we have;
S.I = (525 * 5.5 * 5.43)/100
S.I = $156.79
