Answer:

The 35 pound bag

Step-by-step explanation:

If you divide the price of the 25 pound bag by the number of pounds it has you get 0.81 dollars per pound

20.25 / 25 = 0.81

However if you divide the price of the 35 pound bag by the number of pounds it has you get 0.79 dollars per pound

27.65 / 35 = 0.79

This means you get more dog food for less in the larger 35 pound bag

Formula for the cylinder = V=πr2h

Formula for the cone = 1/3πr²H

Description:

So if the  cone and a cylinder have the same radius and the same height then it will be greater. So plug in these formula.

Formula:

Vcone = 3Vcone

Vcylinder = 360cm³

Vcone = 1/3 360cm³ = 120cm³

Answer: 120cm³

Answer:

BC = 5

Step-by-step explanation:

Since it is an isosceles, it is the base angles that are equal

Since the base angles are equal, then the sides facing these angles are equal

Mathematically, what we are supposed to have as equals should be AB and BC since they are the sides facing the base angles

Thus, BC should be 5

Answer:

I would say Acute. The angle is definitely less than a right angle. Reflex angles are angles more than 180 degrees, but less than 360 degrees.

Answer: She can buy 6 shirts

Step-by-step explanation: You subtract 95 from 240, which gives you 145 so you do 145/22.5 which will give you 6.4444 but you can't buy .44 of a shirt so you round down and you get 6.

The given equation has no solution.

What is equation?

Equation is a statement that show the equality of two expressions connecting by equal sign. for example, 3x - 5 = 20. In this case, 3x - 5 and 20 both are expressions which are connected by equal sign. The two expressions are written on the left side of equal and right side of equal. There are different types of equations such as linear equation, quadatic equation, etc.

The equation is given in the question is 4(x - 8) + 12 = 2(2x -9).

when we find out the solution,

4(x - 8) + 12 = 2(2x -9)

Multiply x with 4 and 2 according to the equation.

4x - 32 + 12 = 4x - 18

4x - 20 = 4x - 18

now, you can see this equation has no solution as the value of x cannot be determined.

Given :

A road 2 m broad surrounds a square park 4225 m² in area.

Size of marble is 25 cm by 8 cm.

Price of each marble is Rs 50.

To Find :

Total cost.

Solution :

Side of square road is :

[tex]A^2 = 4225\ m^2\\\\A = 65\ m[/tex]

Area of road = [tex]4\times 65\times 2 \ m^2=520\ m^2[/tex]

Number of marbles required is :

[tex]N = \dfrac{A}{a}\\\\N = \dfrac{520\times 10^4\ cm^2}{200\ cm^2}\\\\N = 26000[/tex]

It is given that price per marble is Rs 50.

So, total price required is :

[tex]P = Rs \ 50\times 26000 \\\\P = Rs \ 13,00,000[/tex]

Hence, this is the required solution.

the slope is :

[tex] \tan( \alpha ) = 4 \div 2 = 2[/tex]

at a pt on graph , when

[tex]x = 1 \\ y = 3 \\ [/tex]

therefore, coordinates are (1,3)

The equation is :

Answer:

17% of the bill

Step-by-step explanation:

Well to find the answer to this question we first have to add 35 + 48 to get the total percent of the bill that Michelle and Lori paid.

35 + 48 = 83%

now that we know the percent of the bill that Lori and Michelle are paying we have to subtract that amount by 100% to get the percent of the bill that Patti is paying.

100% - 83% = 17%

So Patti is paying 17% of the bill

If we wanted to go even farther and find out what 17% of the bill was all we would have to do is multiply 45 by 17% or 45 x 0.17

45 x 0.17 = 7.65

So Patti is paying 7 dollars and 65 cents

Answer:

Tim purchased 6 video games.

Step-by-step explanation:

Let's set the number of games Time purchased as x.

Due to each game costing $25, the total amount of money used on buying games would be ($25)x.

Hence, as the total amount of money used to buy both the console and the video games would be $350, the equation can be set as:

[tex]\$25x + \$200 = \$350[/tex]

[tex]\$25x = \$(350 - 200)[/tex]

[tex]x = \frac{\$150}{\$25}[/tex]

[tex]x = 6[/tex]

Therefore, Tim purchased 6 video games.

0.57 inches was left

Step-by-step explanation:

Here, we start by calculating the total length of the yam they have

Mathematically, that will be 0.37 + 0.45 = 0.82 inch

Now, to get what is remaining, we subtract what was borrowed

Mathematically, that is 0.82-0.25 = 0.57 inches

Answer:

5 and 6 and -1

6 and 8 and -4

5 and 8 and -2 and -1

Step-by-step explanation:

They all add up to 10.

The trick is to first figure out if you can combine 5 6 or 8 together, then use the negative numbers to subtract as needed to reach you number. If you add 5 and 6, that is 11, but -1 can make 10. When you add 8 and 6, that is 14. But good thing you have the -4 to make 10. You start with the smallest number found from adding together two numbers from the positive pile like 5 and 6.

You can make other combinations as well. 11 could work too.

The pairs of cards are  (-4, 8), (-1, 5) and (-2, 6) respectively.

Addition is a mathematical operation which used to count the things when are together. The addition of two positive integers are greater than both of them while for negative integers it is less than both of them.

Given that,

The different cards having numbers on them are as below,

-4, -2, -1, 5, 6, 8.

In order to select them into three pairs having the same sum make the pair as follows,

Add each positive number to each of the negative numbers and then select the pair of numbers having the same sum.

Thus, it is obtained as,

-4 + 8 = 4

-1 + 5  = 4

-2 + 6 = 4

Hence, the required pairs of cards are (-4, 8), (-1, 5) and (-2, 6) respectively.

Answer:

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y} = 21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Step-by-step explanation:

The question is poorly formatted.

Given

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y}[/tex]

Required

Derive an equivalent expression

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y}[/tex]

Express 18 as 9 * 2

[tex]\sqrt[3]{2y^3} * 7\sqrt{9 * 2y}[/tex]

Split the expression as follows:

[tex]\sqrt[3]{2y^3} * 7\sqrt{9} * \sqrt{2y}[/tex]

Take positive square root of 9

[tex]\sqrt[3]{2y^3} * 7*3 * \sqrt{2y}[/tex]

[tex]\sqrt[3]{2y^3} * 21 * \sqrt{2y}[/tex]

[tex]21*\sqrt[3]{2y^3} * \sqrt{2y}[/tex]

The cube root can be rewritten to give:

[tex]21*\sqrt[3]{2}*\sqrt[3]{y^3} * \sqrt{2y}[/tex]

[tex]\sqrt[3]{y^3} = y^{3*\frac{1}{3}} = y[/tex]

So, we have:

[tex]21*\sqrt[3]{2} * y * \sqrt{2y}[/tex]

Rewrite as:

[tex]21y *\sqrt[3]{2} * \sqrt{2y}[/tex]

Split [tex]\sqrt{2y[/tex]

[tex]21y *\sqrt[3]{2} * \sqrt{2} * \sqrt{y}[/tex]

Collect Like Terms

[tex]21y*\sqrt{y} *\sqrt[3]{2} * \sqrt{2}[/tex]

Represent in index form

[tex]21y*y^{\frac{1}{2}} *2^\frac{1}{3} *2^\frac{1}{2}[/tex]

Apply law of indices

[tex]21*y^{1+\frac{1}{2}} *2^{\frac{1}{3} +\frac{1}{2} }[/tex]

[tex]21*y^{\frac{2+1}{2}} *2^{\frac{2+3}{6}}[/tex]

[tex]21*y^{\frac{3}{2}} *2^{\frac{5}{6}}[/tex]

[tex]21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Hence:

[tex]\sqrt[3]{2y^3} * 7\sqrt{18y} = 21(y^{\frac{3}{2}})(2^{\frac{5}{6}})[/tex]

Answer:

Option A

Step-by-step explanation:

A linear function's standard form is represented by the equation

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept(where the line crosses the y-axis).

So if a function has a slope of 7/2 which is the value of m and crosses the y-axis at 9 which is the value of b then the equation would be

[tex]y=mx+b\\y=\frac{7}{2}x+9[/tex]

So option A is our answer
