The water weight = Pitcher weight when filled - Pitcher weight when empty
= 2.01 - 1.72
= 0.29 kg
Answer:
0.29 kg
Step-by-step explanation:
weight of water = weight of pitcher when full - weight of pitcher when empty
⇒ weight of water = 2.01 - 1.72 = 0.29 kg
Determine the slope and y-intercept given the equation below, explain your answer.
x + y = -1
Answer:
slope is -1, y-intercept is -1
Step-by-step explanation:
x+y=-1
convert to slope-intercept form
y=-x-1
y=-1x-1
slope is -1, y-intercept is -1
Solution:
Let's convert the equation into slope-intercept form.
x + y = -1y = -x - 1In this equation, the slope is the coefficient of x.
The following points can be made:
Since there is a "-" in front of the x variable, the coefficient of x is -1.Since the coefficient is -1, the slope of the line is -1.The y-intercept of the equation will be a constant.
The following points can be made:
Since there is a constant on the RHS, that constant will be the y-intercept.Since the constant on the RHS is -1, the y-intercept of the line is -1.In conclusion...
Slope of line: -1y-intercept of line: -1Need help please! Will give brainliest
Answer:
The answer is 1920 cm
Step-by-step explanation:
First we need to break up to two separate shapes. These shapes are both rectangles, one on the right and one on the left.
To find the volume of a Prism, the equation is V=lwh (length x width x height).
So by splitting up the shape we have two different equation
V= (10)(8)(14) =1120
V= (10)(8)(10)=800
Now we add 1120+800 to get the volume of the entire shape, which is 1920 cm.
If the area of triangle is 360 cm2 and the height is 18cm, find its base
Formula for area of a triangle is 1/2 x base x height.
musing the information given you have:
360 = 1/2 x base x 18
First multiply both sides by 2:
720 = base x 18
Now divide both sides by 18:
Base = 720/18
Base = 40 cm
Solution:
Note that:
Area of triangle = 1/2 x Base x HeightArea of triangle = 360 cm²Height = 18 cmUsing the formula to find the area:
1/2 x Base x Height = Area of triangle=> 1/2 x Base x 18 = 360 cm²=> Base x 9 = 360 cm²=> (Base x 9)/9 = 360/9 cm²=> Base = 40 cmsomeone help, please

Jane got a prepaid debit card with $25 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon
was 21 cents per yard. If after that purchase there was $16.39 left on the card, how many yards of ribbon did Jane buy?
yards
?
Step-by-step explanation:
so, she spent 25-16.39 = $8.61 on the ribbon.
1 yard of the ribbon costs $0.21.
how many yards did she buy with that amount of money ?
well, as many times as 0.21 fits into 8.61 :
8.61 / 0.21 = 41
so, she bought 41 yards of ribbon.
I'm happy to help you today!
Answer:
41 yards is correct
Step-by-step explanation:
Step 1. The information we have is:
Originally Jane had $25 on her debit card.
She made a purchase of bulk ribbon for 21 cents per yard.
And after that she ended up with $16.39 on the card.
Step 2. Make an equation to describe the situation.
The equation that describes this situation is:
[tex]\tt 25-0.21y=16.39[/tex]
Where 25 is the initial amount and to that, we subtract 0.21y, where y is the number of yards that she bought of ribbon. And all of this has to be equal to the final amount of 16.39.
Step 3. Solve the equation for y:
To solve for y, we subtract 25 to both sides of the equation:
⇒ [tex]\tt-0.21y=16.39-25[/tex]
⇒ [tex]\tt -0.21y=-8.61[/tex]
Then, divide both sides of the equation by -0.21:
[tex]\tt y=\frac{-8.61}{-0.21}[/tex]
The result is:
[tex]\tt y=41[/tex]
The answer is 41 yards of ribbon.
Hope this helps you!Have an awesome day! :)[tex]-Nature-[/tex]
Verify the identity.
Answer:
first blank box:
cos^2(a)
second blank box:
sin^2(a)
see image.
Step-by-step explanation:
Usually, to "verify" you work on the equation using algebra and identities...BUT ONLY CHANGING ONE SIDE. Keep the other side the same and try to make them look the same.
The step to get what's in the first blank box is multiplying
(1-cos a)(1+cos a)
which will make a difference of two squares.
The second blank is using a pythagorean identity that
cos^2 + sin^2 = 1
so

Step-by-step explanation:
A school district signs a contract to purchase 50 of the electric typewriters (normally selling for $129.95) from ABC at a quantity discount of 18%. What price does the school district pay for each typewriter?
The price the school district pays for each typewriter is $106.56.
What is the price for each typewriter?A quantity discount is the discount given for bulk purchases. It reduces the purchase price of a good or service.
Total purchase price of the typewriters before the discount = (50 x 129.95) = 6,497.50
Total purchase price of the typewriters after the discount = (100 - 18) x 6,497.50
= $5,327.95
Purchase price of one typewriter = $5,327.95 / 50 = $106.56

The hypotenuse of a 30°-60°-90° triangle measures 8√3 inches. What is the length of the shorter leg?
Answer: 8 inches
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the short side to the long side is 1/sqrt(3).
Therefore the short side is the long side divided by sqrt(3).
So the short side = 8 sqrt(3)/sqrt(3) = 8 inches

11) Tickets to a concert cost either $15 or
$20. A total of 300 tickets were sold and
the total receipts were $5300. How many
of each kind of ticket were sold.
Answer:
There were 140 tickets sold that cost $15 and 160 tickets sold that cost $20.
Step-by-step explanation:
To solve this problem, we should create a system of equations. Let's let the variable x represent the number of $15 tickets sold and let the variable y represent the number of $20 tickets sold. Using these variables, we can make the following equations:
x + y = 300
15x + 20y = 5300
To solve this equation, we can use substitution. Our first step in this case is solving the first equation for one variable; let's choose x.
x = 300 - y
Now, we can substitute this value for x into the second equation.
15(300-y) + 20y = 5300
Next we can distribute through the parentheses on the left side of the equation.
4500 - 15y + 20y = 5300
We can combine like terms on the left side of the equation to simplify.
4500 + 5y = 5300
We should then subtract 4500 from both sides of the equation.
5y = 800
Finally, we can divide both sides of the equation by 5.
y = 160
To solve for x, we can substitute this value for y into either of our original equations, but we should probably choose the first one for simplicity.
x + y = 300
x + 160 = 300
x = 140
Therefore, x = 140 and y = 160; this means that 140 $15 tickets were sold and 160 $20 tickets were sold.
