Answer:
1 1/3 minutes
Step-by-step explanation:
Gasoline is pumped at rate of 3 gallons per minute into a container that already has 4 gallons inside
From the above question, we are to calculate the time at which the gasoline is pumped into the container
Hence:
Time = Number of gallons/Rate
Number of gallons = 4
Rate = 3 gallons per minutes
Hence:
Time = 4 gallons/3 gallon per minutes
Time = 1 1/3 minutes
The time at which the gasoline is pumped into the container is 1 1/3 minutes
Colin buys a car for £45500. It decreases in price 6% per year. How much will it be worth in 3 years?
Answer:
The answer is 33,710 euros.
Step-by-step explanation:
Start by multiplying 45,550 by 6%. This will give 2,730. over the next three years the price decreases, so multiply 2,730 by 3, which is 8,190. Finally, subtract 45,550 by 8,190 to get 33,710.

Solve for x in simplest form.
2= 1/2 (5x-8)
Answer:
x = [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
Given
2 = [tex]\frac{1}{2}[/tex] (5x - 8) ( multiply both sides by 2 to clear the fraction )
4 = 5x - 8 ( add 8 to both sides )
12 = 5x ( divide both sides by 5 )
[tex]\frac{12}{5}[/tex] = x
can someone please tell me how to do 2x=3y and 4x-3y=12 using substitution to solve the system of equations.
Answer:
Step-by-step explanation:
you divide the two to the y, which is x=3/2y
then, you simplify the second equation to y, which is -3y= -4x+12
then, you substitute the x=3/2y into the second equation,
-3y = -6+12
-3y = 6
y = -2
Substitute the y into the first equation, x= 3/2y,
x = -3
What must m∠QPS be for PQRS to be a parallelogram?
Answer:
It’s B
Step-by-step explanation:
For the shape to be a quadrilateral, then the value of ∠QPS must be (b) 59 degrees
For quadrilateral PQRS to be an actual quadrilateral, then:
[tex]\angle RQP = \angle PSR[/tex] --- opposite angles of quadrilateral[tex]\angle QPS + \angle PSR = 180[/tex] --- adjacent angles of quadrilateral[tex]\angle RQP = \angle PSR[/tex] implies that:
[tex]6x + 13 = 7x - 5[/tex]
Collect like terms
[tex]6x - 7x = -13 - 5[/tex]
[tex]-x = -18[/tex]
Multiply both sides by -1
[tex]x = 18[/tex]
[tex]\angle QPS + \angle PSR = 180[/tex] implies that
[tex]\angle QPS + 7x - 5 = 180[/tex]
Substitute 18 for x
[tex]\angle QPS + 7(18) - 5 = 180[/tex]
Collect like terms
[tex]\angle QPS= 180 +5 - 7(18)[/tex]
[tex]\angle QPS= 59[/tex]
Hence, the measure of angle QPS must be (b) 59 degrees

find the area of the triangle formed by the vertex and x-intercepts of parabola y=-x^2-3x+10
Answer:
42.875
Step-by-step explanation:
First you find the x-intercepts and the vertex of the equation.
(-5, 0), (-2, 0), (-3/2, 49/4)
You use those coordinates to find the sides of the triangle and then you use the lengths to find the semiperimeter.
Lastly, you use Heron's formula to compute the area.
The area of the triangle is required.
The area of the triangle is [tex]42.875\ \text{units}^2[/tex]
[tex]y=-x^2-3x+10[/tex]
The x intercepts are
[tex]-x^2-3x+10=0\\\Rightarrow x=\dfrac{-\left(-3\right)\pm \sqrt{\left(-3\right)^2-4\left(-1\right)\times 10}}{2\left(-1\right)}\\\Rightarrow x=-5,2[/tex]
The x intercepts are
[tex](-5,0),(2,0)[/tex]
Distance between them is
[tex]2-(-5)=7\ \text{units}[/tex]
Vertex of a parabola is given by
[tex]x=-\dfrac{b}{2a}\\ =-\dfrac{-3}{2\times -1}\\ =-1.5[/tex]
[tex]y=-(-1.5)^2-3(-1.5)+10=12.25[/tex]
So,
Base = b = 7 units
Height = h = 12.25 units
Area is
[tex]A=\dfrac{1}{2}bh\\\Rightarrow A=\dfrac{1}{2}\times 7\times 12.25\\\Rightarrow A=42.875\ \text{units}^2[/tex]

How many centimeters are there in 2 yards if there are 2.54 centimeters per inch. Show your work and express your answer without rounding.
Answer:
There are 182.88 cm in 2 yards.
Step-by-step explanation:
Given that,
1 inch = 2.54 cm
We need to find how many centimeters are there in 2 yards.
We know that,
1 yard = 36 inch
⇒ 2 yards = (2×36) inches
= 72 inches
It means,
72 inches = (72 × 2.54) cm
= 182.88 cm
Hence, there are 182.88 cm in 2 yards.
Isabelle has $5.45 in her purse. If she has five more nickels than dimes, and twice as many quarters than dimes, how many of each type of coin does she have?
Answer:
Nickel = 13
Dimes = 8
Quarters = 16
Step-by-step explanation:
Let N denote Nickel,
Let D denote dime
Let Q denote quarter
Now, from online conversions;
1 nickel = 5 cents
Also, 1 dime = 10 cents
Also, 1 quarter = 25 cents
Isabelle has $5.45 which is also 545 cents.
Thus, we have;
5N + 10D + 25Q = 545 - - - (eq 1)
We are told that;
she has five more nickels than dimes, and twice as many quarters than dimes.
Thus;
N = D + 5
Also, Q = 2D
Plugging them for N and Q in eq 1 givens;
5(D +5) + 10D + 25(2D) = 545
5D + 25 + 10D + 50D = 545
25 + 65D = 545
65D = 545 - 25
65D = 520
D = 520/65
D = 8
Thus; N = D + 5 = 8 + 5 = 13
Q = 2D = 2 × 8 = 16

You put $500 in the bank, where it earns 1.5% simple interest each year. How long until your money will triple? Pls hurry awnser only if you know
Answer:
133.33
Step-by-step explanation:
In 133.33 years, the principal amount of $500 at the rate of 1.5% per year will triple.
What is simple interest?Simple interest is an interest which is only based on principal amount, it does not imply on yearly interest.
Given that,
The principal amount put in the bank p= $500
The rate of simple interest r= 1.5 %
Amount will be triple, implies that, Interest would be two times of principal.
Interest = 2 x 500 = 1000
To find the time t, when amount gets triple, use simple interest formula
Interest = (p x r x t)/100
1000 = (500 x 1.5 x t)/100
200/1.5 = t
133.33 = t
The required time in which the money will triple is 133.33 years.
