write y = (-5/8)x + 3 in standard form using integers.
a. 5x + 8y = -24
b. 5x + 8y = 24
c. 5x - 8y = 24
d. -5x + 8y = 24

Answers

Answer 1

To write this in standard form, you need to eliminate the fraction in the coefficient of variable x. You can do this by multiplying 8 to the two sides of the equation:

8(y) = 8[(-5/8)x + 3]

8y = -5x + 24

Transpose the variable x to the other side:

5x + 8y = 24

Tangent:

We know that,

Tangent to a circle is the line that touches the circle at only one point. There can be only one tangent on a point to circle. The Tangent makes an angle of [tex]90^{\circ}[/tex] with the radius of the circle at the point of contact.

This is the first part of a three-part problem. express $18\sqrt 8$ in the form $a\sqrt b$, where $a$ and $b$ are integers and $b$ is as small as possible.

Answers

Answer:

[tex]18\sqrt{8}=36\sqrt{2}[/tex]

Where a=36 and b=2 with b is small.

Step-by-step explanation:

Given problem [tex]18\sqrt{8}[/tex]

We have to write the given problem in form of [tex]a\sqrt{b}[/tex], where a and b are integers and b is as small as possible.

Consider the given problem [tex]18\sqrt{8}[/tex]

8 can be written in factored form as 2 × 2 × 2

Substitute, in given problem, we have

[tex]18\sqrt{8}=18\sqrt{2 \times 2\times 2}[/tex]

This can be written as,

[tex]18\sqrt{2 \times 2\times 2}=18(\sqrt{4}\sqrt{2})[/tex]

We know [tex]\sqrt{4}=2[/tex] , thus,

[tex]18(\sqrt{4}\sqrt{2})=18\cdot 2\sqrt{2}=36\sqrt{2}[/tex]

Thus,[tex]18\sqrt{8}=36\sqrt{2}[/tex]

Where a=36 and b=2 with b is small.

How do you make 3ln2+2ln4 a single logarithm?

Answers

3ln 2 = ln 2³ = ln 8
2ln 4 = ln 4² = ln 16
Sum means it is a product:
ln (8 × 16) = ln 128

Or ln (2³×4²)

You can do on this way 
3ln2 + 2ln4 = ln 2^3 + ln 4^2 = ln 8 + ln 16 = ln 128

To round a number to the tenth, any number greater than or equal to 5 will round up and anything less than 5 round down.

f(x)=2x^2-3x+1

A.It is a one-to-one function.
B.It fails the vertical line function.
C.It is a many-to-one function.
D.It is not a function.

Answers

it is a parabola, there are two x values (symmetrical across the line x=-b/2a)for the same y value, so it is a many-to-one function. 

f(x)=2x^2-3x+1

the graph of the function is attached with the answer

As we can see that equation is quadratic and its graph is a parabola facing upward.

As we can see it passes the Vertical line test

As it passes the Vertical line test , So it is a function

And two values of x has one value of y

So it is a many to one function.


Express 8.12 as a mixed number.

Answers

8.12 as a mixed number is 203/25
Hey there!

Let's keep our goal in mind. A mixed number is a whole number and a fraction together. SInce we already have our whole number, 8, we need to make .12 a fraction.

If we look at .12, we see that that 12 is in the hundredths place. When you go to whole numbers, you have tens, hundreds, and so on. When you go to fractions, it goes tenths, hundredths and so on.

That means that since the 12 is in the hundredths, it's 12 hundredths, or 12/100. 

That means our mixed number is 8 12/100

Answers

17/18.2=.934 x/18=.934 18*.934 = 16.812
Or 16.81 or 16.8 simplified

Answer:

23.4 in

Step-by-step explanation:

The only side of SFN we know the measurement of is FS, which is 18.2.  We see from the similarity statement that FS corresponds to QB, which is 14.  This gives us the ratio

14/18.2.

From the similarity statement, we see that FN corresponds to QH; this gives us the ratio

18/x

Together this gives us the proportion

14/18.2 = 18/x

Cross multiplying gives us

14(x) = 18.2(18)

14x = 327.6

Divide each side by 14:

14x/14 = 327.6/14

x = 23.4

Jorge is filling 14 cups per minute, which is faster than Mary.
Jorge is filling 28 cups per minute, which is faster than Mary.
Mary is filling 18 cups per minute, which is faster than Jorge.
Mary is filling 36 cups per minute, which is faster than Jorge.

Answers

Answer:

Mary is filling 36 cups per minute, which is faster than Jorge.

Step-by-step explanation:

Lets get Jorge's time :

As the rate is constant, we can find the slope to know the number of cups he is filling per minute.

Slope is found using: [tex]\frac{y2-y1}{x2-x1}[/tex]

= [tex]\frac{53-25}{5-3}[/tex]

= [tex]\frac{28}{2}=14[/tex]

From the table lets get Mary's time:

[tex]\frac{99-81}{1-0.5}[/tex]

= [tex]\frac{18}{0.5}=36[/tex]

Another data: [tex]\frac{63-45}{2-1.5}[/tex]

=  [tex]\frac{18}{0.5}=36[/tex]

Therefore, we can see that Mary is filling 36 cups in a minute and Jorge is filling 14 cups.

Hence, the correct answer is : Mary is filling 36 cups per minute, which is faster than Jorge.

Answer:

Mary is filling 36 cups per minute, which is faster than Jorge.

Step-by-step explanation:

A cylindrical container holding sugar has a height of 15 inches and a diameter of 4 inches. Which of the following is the closest to the volume of the sugar container?

A.
707 cubic inches
B.
94 cubic inches
C.
754 cubic inches
D.
188 cubic inches

Answers

v=(h)(pi)(r^2)
say pi=3.14
h=15
d/2=r=4/2=2

so
v=(15)(3.14)(2)^2
v=(15)(3.14)(4)
v=(60)(3.14)
v=188.4


so answer is D

Using the formula V = πr²h, the volume of the cylinder is calculated as 188.4954 cubic inches, which can be rounded to 188 cubic inches, corresponding to answer choice D.

To calculate the volume of the cylindrical container holding sugar, we can use the formula for the volume of a cylinder, which is V = πr²h. Here, π is a constant (approximately 3.14159), r is the radius of the cylinder, and h is the height of the cylinder.

The diameter of the container is given as 4 inches, so the radius (r) is half of the diameter, which is 2 inches. The height (h) is given as 15 inches. Plugging these values into the volume formula, we get:

V = π(2 inches)²(15 inches)
= π(4 square inches)(15 inches)
= 60π cubic inches

Using 3.14159 as the value for π, the volume calculates to:

V = 60 * 3.14159 cubic inches = 188.4954 cubic inches

So, the closest estimate to the volume of the sugar container would be 188 cubic inches, which corresponds to answer choice D.

A theater charges $25 for adults and $15 for children. When the price of a child's ticket increases to $18 next year,the cost for a dance club to attend the theater will increase from $450 to $480. Write and solve a system of equations to find how many adults are in the dance club.

Answers

Given:
tickets for adults - 25
tickets for kids - 15
initial cost - 450
increase in tickets for kids to - 18
cost after increase - 480

let x be number of adults and y be number of kids

25x + 15y = 450
25x + 18y = 480

subtraction:

25x + 15y = 450
-25x - 18y = -480
 0      - 3y = - 30
         y = -30/-3
         y = 10

There are 10 kids.

25x + 15y = 450
25x + 15(10) = 450
25x + 150 = 450
25x = 450 - 150
25x = 300
x = 300/25
x = 12

There are 12 adults.

All in all there are 12 adults and 10 kids.

to check:
25x + 15y = 450
25(12) + 15(10) = 450
300 + 150 = 450
450 = 450

25x + 18y = 480
25(12) + 18(10) = 480
300 + 180 = 480
480 = 480
