Answer:

77°F

Step-by-step explanation:

Just plug in 25 into the C variable and you get your answer.

Answer:

77°F

Step-by-step explanation:

You are given 25° as the temperature in celsius, so first replace the C in the equation with 25. You should get:

[tex]\frac{9}{5}(25) + 32[/tex]

Next, multiply 9/5 (or 1.8, they're the same thing) with 25. You should get 45.

Lastly, add 32 to 45. The sum is 77.

You're finished simplifying the equation, so the answer is 77°F.

Given:

[tex]6x+3y=12[/tex]

[tex]2x-6y=18[/tex]

[tex]5x+2y=16[/tex]

[tex]6x-8y=-24[/tex]

To find:

The slope intercept form of each equation.

Solution:

We know that, slope intercept form of a line is

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

where, m is slope and b is y-intercept.

The first equation is

[tex]6x+3y=12[/tex]

Subtract 6x from both sides.

[tex]3y=12-6x[/tex]

Divide both sides by 3.

[tex]y=\dfrac{12-6x}{3}[/tex]

[tex]y=\dfrac{12}{3}-\dfrac{6x}{3}[/tex]

[tex]y=4-2x[/tex]

[tex]y=-2x+4[/tex]

Therefore, the slope intercept form of first equation is [tex]y=-2x+4[/tex].

Similarly,

[tex]2x-6y=18[/tex]

[tex]-6y=18-2x[/tex]

[tex]y=\dfrac{18-2x}{-6}[/tex]

[tex]y=-3+\dfrac{1}{3}x[/tex]

[tex]y=\dfrac{1}{3}x-3[/tex]

Therefore, the slope intercept form of second equation is [tex]y=\dfrac{1}{3}x-3[/tex].

[tex]5x+2y=16[/tex]

[tex]2y=16-5x[/tex]

[tex]y=\dfrac{16-5x}{2}[/tex]

[tex]y=8-\dfrac{5}{2}x[/tex]

[tex]y=-\dfrac{5}{2}x+8[/tex]

Therefore, the slope intercept form of third equation is [tex]y=-\dfrac{5}{2}x+8[/tex].

[tex]6x-8y=-24[/tex]

[tex]-8y=-24-6x[/tex]

[tex]y=\dfrac{-24-6x}{-8}[/tex]

[tex]y=\dfrac{-24}{-8}-\dfrac{6x}{-8}[/tex]

[tex]y=3+\dfrac{3}{4}x[/tex]

[tex]y=\dfrac{3}{4}x+3[/tex]

Therefore, the slope intercept form of fourth equation is [tex]y=\dfrac{3}{4}x+3[/tex].

Step-by-step explanation:

To multiply

(5x² - 6x + 2)(4x² - 3x)

Each term in the second factor is multiplied by each term in the first factor, that is

5x²(4x² - 3x) - 6x(4x² - 3x) + 2(4x² - 3x) ← distribute parenthesis

= 20[tex]x^{4}[/tex] - 15x³ - 24x³ + 18x² + 8x² - 6x ← collect like terms

Okay so ur at a party and they have donuts, 5/25 of the donuts are eaten. What percent of them are left?

If it's not too much trouble could you explain how to solve it? If not I guess I'll live:(

Answers

Answer:

80%

Step-by-step explanation:

100%= 25/25. 1 donut = 5%. So you have 20 donuts left x 5.

Answer:

80% are left.

Step-by-step explanation:

So 100 donuts would be 100%. To get to 100 you need to multiply 25x4. Then you also need to multiply 5x4=20. Since it is the 5 that are eaten, you subtract 20 from 100 and get 80, so you are left with 80% of the donuts.

Which function is best represented by the graph?

Answers

Answer:

J

Step-by-step explanation:

First look at the y-intercept. When y=0, you get 8 on the graph, so in the equation it has to give you 8 as well.

This narrows it down to F G J

Next, the slope of the graph is negative because its tilting downwards.

This narrows it down to G J

Finally, on the graph when y=0, you get 6, so the equation has to meet this too

With your choices narrowed down to G and J, calculate the x-intercepts.

0= -4/3x+8

-8= -4/3x

-8(-3/4)=x

x=6

Answer:

The answer is J

Step-by-step explanation:

the y-intercept is 8 and to find the slope you count rise over run, well the graph is too small to tell what points are actually on the lines, but it's given that (0,8) and (6,0) are points. making the rise/run= to 8/6 and then simplify to 4/3. and you can tell that the slope is negative because it's going downward from left to right.

Which statements accurately compare the functions in the graph? Select two options.

Neither function has a maximum value.
The functions share a y-intercept of –1.
The functions share an x-intercept of 1.
Both functions have a range of all real numbers.
Both functions have a domain of all real numbers.

Answers

Answer:

The functions share a y-intercept of –1.

Both functions have a range of all real numbers.

Step-by-step explanation:

They are marked on the y axis with the point, (0,-1)

Secondly, becuase both go along the range, or y axis line, I believe it is is both functions have an all real numbers range.

Hope this helps, let me know if I'm wrong.

The functions share a Y-intercept of –1.

Both functions have a range of all real numbers.

What is real number?

Real number is a set of numbers that has integers, rational numbers, and natural numbers.

Here, we can see, both the functions meet on the Y-axis at a point (0,-1).

Therefore, Both the functions share a Y-intercept of –1.

Again, both the functions have a certain value of Y for a given value f X. Hence, both functions have a range of all real numbers.

The second competition is to see which team can collect three full buckets of seashells the fastest. It takes your team one minute to collect 0.5 buckets of shells. How long does it take your team to collect 3 full buckets of seashells

Answers

Answer:

6 minutes

Step-by-step explanation:

From the question, we are told that your team takes one minute to collect 0.5 buckets, this can be expressed as;

1 minute = 0.5 buckets

To determine the time it will take to collect 3 full buckets of seashells, we will say;

x minute = 3 buckets

Divide both expressions;

1/x = 0.5/3

Cross multiply;

0.5x = 3 *1

0.5x  = 3

Divide both sides by 0.5

0.5x/0.5 = 3/0.5

x = 6

Hence it will take 6 minutes to collect 3 full buckets of seashells

Find the missing side length of the right triangle below

Answers

the missing side length should be 7

The length of base of the triangle is given by BC = 7 feet

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the base of the triangle BC = a

Let the hypotenuse of the triangle be c = 25 feet

Let the height of the triangle be b = 24 feet

And , For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

So , the base BC = √ ( 25 )² - ( 24 )²

The base of the triangle BC = √ ( 625 - 576 )

The base of the triangle BC = √ ( 49 )

The base of the triangle BC = 7 feet

Hence , the length of base of triangle is 7 feet
