During dance practice, Sasha drank 21⁄2 pints of water, and on the way home she drank 1⁄2 cup of water. How much water did she drink in total?

Answers

Sasha drank a total of 51⁄2 cups of water by converting the pints to cups and then adding the half cup she drank on the way home.

To calculate the total amount of water Sasha drank, we need to add the volume of water she drank during practice and the volume she drank on the way home. However, we first need to convert the measurements so that they are in the same unit.

There are 2 cups in a pint, so 21⁄2 pints of water is equivalent to 5 cups of water (since 2 pints = 4 cups and 1/2 pint = 1 cup). Adding the additional 1/2 cup she drank on the way home gives us:

5 cups (from 21⁄2 pints)+ 1/2 cup (drank on the way home)

5 + 1/2 = 51⁄2 cups in total

Therefore, Sasha drank a total of 51⁄2 cups of water.

Sam bought 9 new baseball trading cards to add to his collection. The next day his dog ate half of his collection. There are now only 38 cards left. How many cards did Sam start with?

Answers

Let x be the number of cards he had at first.

He bought 9 new cards:
x + 9

His dog ate half (Which means he also had half left)
0.5(x+9)

There are 38 cards left:
0.5(x+9) = 38
0.5x + 4.5 = 38
0.5x = 38 - 4.5
0.5x = 33.5
x = 33.5 ÷ 0.5 
x = 67

So Sam had 67 cards to start off with.

Note: You may want to write 0.5 as half (1/2) .. it is just clumsy to type that, so I kept it as decimal.

The volume of a cylinder varies jointly with the square of the radius and the height. If the volume of a cylinder is 50.265 cubic inches when the radius is 2 inches and the height is 4 inches, what is the volume when the radius is 3 inches and the height is 7 inches?

Answers

just use the formula v = pi.(r^2).h that gives v = 9pi.7 that gives approximately 197.92 cubic inches.

Answer with Step-by-step explanation:

The volume of cylinder is given by

V=πr²h

Where r is the radius and h is the height

The volume of a cylinder is 50.265 cubic inches when the radius is 2 inches and the height is 4 inches.

50.265=π×2²×4

⇒ π=50.265/16

Now when r=3 inches and h=7 inches

V=π×3²×7

[tex]V=\dfrac{50.265}{16}\times 9\times 7\\ \\V=199.336[/tex]

Hence, volume of the cylinder when the radius is 3 inches and the height is 7 inches is:

Three​ golfers, Vijay,​ Ernie, and Phil​ , during five years had a total of 221 ​top-10 finishes. Ernie had 13 more​ top-10 finishes than Phil. Vijay had 16 more​ top-10 finishes than Phil. Determine the number of​ top-10 finishes for each golfer.

Answers

For this case what you must do first is to define the following variables:
 x: number of top-10 finishes for Vijay.
 y: number of top-10 finishes for Ernie.
 z: number of top-10 finishes for Phil.
 We write the following system of equations:
 x + y + z = 221
 y = 13 + z
 x = 16 + z
 Solving the system we have:
 Step 1:
 x + y + z = 221
 (13 + z) + (16 + z) + z = 221
 3z + 29 = 221
 z = (221-29) / (3)
 z = 64
 Step 2:
 y = 13 + z
 y = 13 + 64
 y = 77
 Step 3:
 x = 16 + z
 x = 16 + 64
 x = 80
 Answer:
 the number of top-10 finishes for each golfer is:
 Vijay: 80
 Ernie: 77
 Phil 64

John is walking home with his younger brother, Don. Their home is on opposite corner of a rectangle lot with dimensions of 500 feet by 800 feet. John decides to walk along two sides of the lot, While don takes the diagonal path home. About how much farther does john walk than don?

Answers

The distance  via the diagonal is calculated by the Pythagoras theorem:-

Diagonal = sqrt ( 500^2 + 800^2) =  943.4 feet.

Distance along 2 sides of rectangle = 500 + 800 = 1300 feet

So John walks 1300 - 943.4 = 356.6 feet more than Don.


The distance that John walk more than Don is 356.60 ft.

What is a rectangle?

A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but reverse statement may or may not be true.

Given that John is walking home with his younger brother and their home is on opposite corner of a rectangle lot with dimensions of 500 feet by 800 feet.

Since John is walking on the sides, the lenght covered by John will be the sum of the sides.

Sum of the sides of the rectangle = 500 ft + 800 ft

Sum of the sides of the rectangle = 1300 ft

Further, Don is walkin on the diagonal, the lenght covered by Don will be the diagonal of the rectangle.

(Diagonal)² = (500 ft)² + (800 ft)²

(Diagonal)² = 250000 ft² + 640000 ft²

Diagonal²  = 890000 ft²

Diagonal  = 943.39811 ft

The distance that John walk more than Don is:

Distance = 1300 ft - 943.39811 ft = 356.60 ft

Latifah makes $12 per hour. She works 18 hours per week. She calculates that in 4 weeks, she will earn $864. If her hourly rate and weekly hours are rounded to the nearest ten, which amount represents an estimate of the amount she will make over 4 weeks? Is her original calculation reasonable?

Answers

here is the steps to figure it out with the answer: 
she makes $216 per week. If her hourly rate and weekly hours are rounded to the nearest tenth then it would make her weekly pay $200. Her hourly pay is now $10 and her weekly hours are 20. Now multiply the 20 (weekly hours) by 4 (which would be 4 weeks) 20x4= 80. So 80 hours in 4 weeks. Now her hourly pay is $12 rounded to the nearest tenth = $10 per hour. SOOO the $10 multiplied with the 80= $800 in 4 weeks. 

Answer and step-by-step explanation:

Rounding her hourly rate to the nearest ten, we get $10.  

Rounding her number of hours to the nearest ten, we get 20.

This gives us an estimate of 10(20)(4) = $800

Her original calculation is reasonable; it is higher because the actual hourly rate is larger than the estimate, so her amount of pay should be higher than the estimate.

Write an equation in slope- intercept form of the line through points S(-7,-6) and T(10,8)

Answers

Final answer:

The slope-intercept form of the line passing through points S(-7,-6) and T(10,8) is calculated by first determining the slope or 'rise over run' which is 14/17. Subsequently, the slope and point T(10,8) are used to find the y-intercept which is -8/17. Hence, the equation of the line is y = 14/17x - 8/17.

Explanation:

To create an equation in the slope-intercept form we first need to find the slope or rise over run given our two points S(-7,-6) and T(10,8). The formula to find the slope (m) = (y2 - y1) / (x2 - x1). By substituting the values into the formula we get (8-(-6)) / (10-(-7)) = 14/17, which is our slope (m).

Next, we use the slope (m) and one point, let's take T(10,8), in the equation y = mx + b to find the y-intercept (b). Substituting the known values into the equation gives us 8 = 14/17*10 + b. Solving for b gives us b = -8/17.

Therefore, the slope-intercept form of the line passing through the given points S(-7,-6) and T(10,8) is y = 14/17x - 8/17.

Final answer:

To write the equation of a line in slope-intercept form, find the slope and y-intercept. For the points S(-7,-6) and T(10,8), the equation is y = (14/17)x + 70/17.

Explanation:

To write the equation of a line in slope-intercept form, we need to find the slope (m) and the y-intercept (b). The slope can be found using the formula:

m = (y2 - y1) / (x2 - x1)

After finding the slope, we can substitute it along with one of the given points into the slope-intercept form equation: y = mx + b, where y and x are the coordinates of any point on the line. Solving the equation will give us the value of the y-intercept.

So, for the given points S(-7,-6) and T(10,8),  

Find the slope: m = (8 - (-6)) / (10 - (-7)) = 14/17Substitute the slope and one point into the slope-intercept form equation: Solve for b: -6 = -98/17 + b, b = -6 + 98/17, b = 70/17Therefore, the equation in slope-intercept form is: y = (14/17)x + 70/17

Tamera earned an A on 5/8 of her spelling tests.Of those spelling tests,she earned a perfect score on 1/5 of them.
On what fraction of tamera's total spelling tests did she earn a perfect score?
If Tamera took 32 spelling test,on how many did she earn a perfect score?

Answers

To answer this, you would read what is being asked very carefully and then represent it using math. The first question asks what fraction of her total spelling test did she earn a perfect score. Going back to the part of the sentence that talks about a perfect score you will see that it says she earned a perfect score on 1/5 of them(referring to the Number of tests she earned an A on). The fraction of tests she earned an a on was five eights. This means that 1/5 of the 5/8 is how many she scored perfect on. Adding to that, 1/5 of the 5/8 of all 32 tests she took she scored a perfect score on. In math this is represented by 1/5 x 5/8 x 32. Cross cancel the 5s and make 32 a 4 and the 8 a 1, and then multiply all numerators across the top and all denominators across the bottom to get 4/1, or 4 perfect scores.
