If the length of a leg of a triangle is 39.2 and the area of the triangle is 63 what is the length of the other leg

Answer:

y = [tex]\frac{1}{5}[/tex] x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = [tex]\frac{1}{5}[/tex], hence

y = [tex]\frac{1}{5}[/tex] x + c ← is the partial equation

To find c substitute (- 10, 6) into the partial equation

6 = - 2 + c ⇒ c = 6 + 2 = 8

y = [tex]\frac{1}{5}[/tex] x + 8

Answer:

33 degrees

Step-by-step explanation

I used arcos, ∠A = arccos((a2 + b2 - c2)/2ab)

b, 33 degrees is correct

Answer:

See Explanation Below :)

Step-by-step explanation:

To solve a pair linear equations by graphing, you would first need to find the slope and y-intercept of each of the equation and then graph it in a coordinate plane. Then, you would see where the two lines intersect, and the coressponding coordinates for that point will be your solution.

Example:

y = 2x +2

y = x -1

For the first equation we know the slope (m) is 2 becuase y = mx + b, and m is 2. We know that the y intercept (b) is also 2 becuase y = mx + b, and b is 2.

Similarly, for the second equation the slope (m) is 1 and the y-intercept (b) is -1.

When you use this data and plot the two lines, we can see that they intersect on the 3rd quadrant at (-3,-4) which will be your solution. See the attached graph for this example.

Answer:

73.92 miles

Step-by-step explanation:

Formula for calculating distance = speed × time

Rate/speed of cyclist from city A = ( x - 3 ) mph , Time Taken = 5 Hours

Rate/speed of cyclist from city B = x mph

If Cyclist from B had started moving 30 minutes later

Time Taken by cyclist from B = 4.5 Hours

If B had started 30 minutes later, then the two cyclist would have met 31.8 miles from A.

distance covered by cyclist from A = 31.8

Solution:

For city A:

distance = speed × time                                                

31.8  = ( x - 3 ) × 5     ⇒   [tex]\frac{31.8}{5}[/tex] = x - 3

6.36 = x - 3    ⇒   x = 6.36 + 3   ⇒    x = 9.36 mph

For city B:  

distance =  speed × time

              =  9.36 × 4.5

              =  42.12 miles

Distance between A and B = 31.8 + 42.12

                                             = 73.92 miles

To Find all the different ways the truck could be, you would mutiply all the choices together.

There were three different choices.

Multiply the two known ones together than divide the total different ways by that to find the third choice.

4 x 2 = 8

96 / 8 = 12

There are 12 colors available.

Answer:

There are 12 colors available

Step-by-step explanation:

We have product rule which states that if there are [tex]n_{1}[/tex] ways of doing one task, and [tex]n_{2}[/tex] ways of doing another task then there  [tex]n_{1}n_{2}[/tex] ways of doing the tasks together.

Let us assume that there are x choices for colors

so we have 4 ways of selecting engines , 2 ways of selecting transmissions and x ways of selecting colors

number of ways of truck could be equipped = [tex]4*2*x[/tex]

                                                                          = [tex]8x[/tex]

it is given that number of ways truck could be equipped= [tex]96[/tex]

so we have

[tex]8x= 96[/tex]

[tex]x=\frac{96}{8}[/tex] ( divide both side by 8)

[tex]x= 12[/tex]

There are 12 colors available

Answer:

y = - [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x - 3y = 4 into this form

Subtract 5x from both sides

- 3y = - 5x + 4 ( divide all terms by - 3 )

y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{4}{3}[/tex] ← in slope- intercept form

with y- intercept c = - [tex]\frac{4}{3}[/tex]

Method 1: Plunging in 0 for x in the equation and solve for y

5(0) - 3y = 4

0 - 3y = 4

-3y= 4

y = [tex]\frac{-4}{3}[/tex]  <<< y - intercept

Method 2: Converting the equation to slope-intercept form ( y = mx + b) and see what b is (that is the y-intercept). Do do this isolate y

-3y = 4 - 5x

y = [tex]\frac{-4}{3} +\frac{5}{3} x[/tex]

[tex]y = \frac{5}{3} x- \frac{4}{3}[/tex]

b = [tex]\frac{-4}{3}[/tex]  <<< y - intercept

Y- intercept : (0, [tex]\frac{-4}{3}[/tex])

Hope this helped!

Answer:

x = [tex]\frac{12}{5}[/tex]

Step-by-step explanation:

Multiply all terms in the equation by the lowest common multiple of 3 and 5, that is 15. This will eliminate the fractions in the equation

10(1 - 2x) - 30x = - 6 + 20(2 - 3x) ← distribute and simplify both sides

10 - 20x - 30x = - 6 + 40 - 60x

10 - 50x = 34 - 60x ( add 60x to both sides )

10 + 10x = 34 ( subtract 10 from both sides )

10x = 24 ( divide both sides by 10 )

x = [tex]\frac{24}{10}[/tex] = [tex]\frac{12}{5}[/tex]

Tom takes 1 day to clear 1 acre.

To find out how many days it takes Tom to clear 1 acre, we can calculate the rate at which he clears brush in acres per day.

Let's use the given information:

[tex]\frac{2}{3}[/tex]​  acre cleared in 2 days,

​ [tex]1\frac{2}{3}[/tex] acres cleared in 5 days,

[tex]2 \frac{1}{3}[/tex]  acres cleared in 7 days.

First, let's find the rate in acres per day for each interval:

For the first interval:

​[tex]\frac{\frac{2}{3} }{2} = \frac{1}{3}[/tex] acre per day.

For the second interval:

[tex]\frac{1\frac{2}{3} }{5} = \frac{5}{3} \times \frac{1}{5} = \frac{1}{3}[/tex]  acre per day.

For the third interval:

[tex]\frac{2\frac{1}{3} }{7} = \frac{7}{3} \times \frac{1}{7} = \frac{1}{3}[/tex] acre per day.

It appears that the rate at which Tom is clearing brush is consistent at

[tex]\frac{1}{3}[/tex]  acre per day.

Therefore, Tom takes 1 day to clear 1 acre.

Step-by-step explanation:

we know that

The rectangles that make up the net for a prism are six rectangles

two rectangles are L by W ----> 12 cm by 9 cm

two rectangles are L by H ----> 12 cm by 5 cm

two rectangles are W by H ---> 9 cm by 5 cm

Final answer:

The rectangular prism net Darren is painting consists of two 12x5 cm rectangles for the top and bottom, two 9x5 cm rectangles for the front and back, and two 12x9 cm rectangles for the sides.

Explanation:

Darren is working on an art project involving painting a wooden block that is in the shape of a rectangular prism. To understand the net for this prism, we need to describe the rectangles that would make it up when the prism is unfolded into a flat shape.

The net of a rectangular prism is made up of six rectangles, each corresponding to a face of the prism. For Darren's block, which has dimensions of 12 cm in length, 9 cm in width, and 5 cm in height, we can determine the rectangles as follows:

When painting, Darren would treat each of these rectangles as separate sections to ensure complete coverage.

Answer:

-18b^8.

Step-by-step explanation:

To simplify an expression, we combine the elements that are similar (look the same).

So, it we have -20b^8 + 2b^8, we see that there are 2 terms with b^8.  We need to simplify them.

So, we have -20b^8 + 2b^8, that addition leaves -18b^8.

-18b^8 cannot be simplified more.

Answer:

{0, 4 and -3}

Step-by-step explanation:

f(x)=x^3-x^2-12x can be factored, starting by taking out the 'x' factor:

f(x)=x^3-x^2-12x = x(x^2 - x - 12), and then by factoring the quadratic:

f(x) = x(x - 4)(x + 3) = 0

Then the zeros are {0, 4 and -3}.

Answer:

The zeros are;

x=-3,x=0, and x=4

Step-by-step explanation:

The given polynomial is

[tex]f(x)=x^3-x^2-12x[/tex]

We equate the function to zero to obtain;

[tex]fx^3-x^2-12x=0[/tex]

We factor the GCF to get;

[tex]x(x^2-x-12)=0[/tex]

We split the quadratic trinomial to get;

[tex]x(x^2-4x+3x-12)=0[/tex]

Factor by grouping

[tex]x(x(x-4)+3(x-4))=0[/tex]

[tex]x(x-4)(x+3)=0[/tex]

The zeros are;

x=-3,x=0, and x=4

The correct option that represents the total area of the rectangle using the distributive property is B) (4 x 3) + (4 x 2) = 20 square units.

The correct option that represents the total area of the rectangle using the distributive property is B) (4 x 3) + (4 x 2) = 20 square units.

The distributive property states that when you multiply a number by a sum or difference of numbers, you can multiply each number individually and then add or subtract the products.

In this case, the rectangle has a length of 4 units and a width of 3 units.

So, the area of the rectangle can be found by multiplying the length by the width, which is 4 multiplied by 3. Then, you add the product of the length multiplied by the width, which is 4 multiplied by 2. This gives us a total area of 20 square units.

Answer: x=8

Step-by-step explanation: Since we know that segment AB and BC are the same measure indicated by the black lines running perpendicular to the lines in triangle themselves, we know that angle A and angle C are the same measure. This means we know this equation... Solve this to complete step 1...

69°=(9y-3)°

If you solve for y, you should get 8. This means that y=8. In knowing that a triangle's interior angles add up to 180°, we know that Angle B must be... Solve this equation for step 2...

∠B=180°-(∠A+∠C)

If you solve to find angle B, you should get that ∠B=42°. Knowing this, we can set up another equation similar to that in step 1 (when we found y knowing the angle) to find x... Solve this equation for your third and final step...  

42°=(5x+2)°

If done step 1 through 3 correctly, you should get x to be equal to... and the final answer... x=8

Answer:

B grade

Step-by-step explanation:

75 + 90 + 88 + 86 = 339

339/4 = 84.75

Grade B = 80-89%

Answer:

Betty will get 85 grade.

Step-by-step explanation:

Betty scored 75,90,88,72, and 86 on her tests.

As given the teacher throws out the lowest grade, we will not consider 72.

Now the teacher averages the remaining grades, and round up to the nearest integer.

So, taking the average we get;

[tex]\frac{75+90+88+86}{4}[/tex]

= 84.75

Rounding this to nearest integer, we get 85.

Hence, Betty will get 85 grade.

Answer:

0.67

Step-by-step explanation:

Answer:

0.25, 25%, or 1/4

Step-by-step explanation:

There are two possibilities for each coin: heads or tails. So the chance of getting heads for the first flip is 50%, or 1/2. To find the probability for both, you multiply 1/2*1/2 and get 1/4.

The probability that both of the coins land on heads up when two coins are flipped is 1/4. This can be obtained by obtaining the possible outcomes and using formula for probability.

The formula of Probability is,

P= number of favorable outcomes/ total number of outcomes

(H,H), (H,T), (T,H), (T,T), that is, the total number of outcome is 4.

that is, the number of favorable outcome is 1.

Hence the probability that both of the coins land on heads up when two coins are flipped is 1/4.

Answer:

x = - 6

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] x² = 24 ( multiply both sides by 3 )

2x² = 72 ( divide both sides by 2 )

x² = 36 ( take the square root of both sides )

x = ± [tex]\sqrt{36}[/tex] ← note plus or minus

x = ± 6

solutions are x = - 6, x = + 6

The smallest solution is x = - 6
