For a given right triangle side a=76.4 ft and side b=39.3 ft. What is the measure of angle A to the nearest degree?

Answer:

[8, inifinity sign)

Step-by-step explanation:

(2)/1 x -1/2 (greater than or equal to sign) 4(2), You need to get rid of the fraction so times 2 on both sides.

So the fraction cancels out and your answer is x (greater than or equal to) 8

The open side of the sign always is facing the bigger number so like this > so x is positive.

Since i can't show the number line i'll try to explain it if it's a greater than sign its a closed dot on the 8 going right. The 8 is in a bracket and the infinity is with a parenthesis. like this [8, infinity sign)

My teacher may have taught me different but it should be about the same.

Hope my answer has helped you and if not i'm sorry.

The  graph y < 2x - 1 is a dotted line which rises to the right with  a slope of 2 and passes through y = -1  and is shaded below the line. The graph y > -2 x +  2 rises to the left and passes through y = 2 and is shaded above the line.

Answer:

W+100=M

Explanation:

So the problem says there will always be 100 more men than woman. So that would mean you just have to add the amount of women and 100 to find the number of men. For example, if there are 3 women, there will be 103 men.

Hope this helps ;)

Certainly! To create an algebraic equation representing the given situation, we can use the information that there are 100 more men than women at the school.

Let's use the variables:
- \( W \) to represent the number of women
- \( M \) to represent the number of men

The key piece of information that we have is that the number of men is 100 more than the number of women. We can write this relationship with an equation:

\[ M = W + 100 \]

This equation states that if you take the number of women (\( W \)) and add 100 to it, you will get the number of men (\( M \)). It directly translates the information given into an algebraic equation, showing the relationship between the number of women and the number of men in the school.

Answer:

Step-by-step explanation:

It is congruent to the other side.

Answer:

5.2% increase

Step-by-step explanation:

In 2015 the total population was 750.

In 2016 the total population was 17% more than in 2015, so 750 x 1.17 = 877.

In 2017 the total population was 10% less than in 2016, so 877 x 0.9 = 789.

Compared to 2015, the population in 2017 was 789/750 = 1.052 or 5.2% greater.

In one step:

((750 x 1.17) x 0.9) / 750 = 5.2%

In this question, we're going to need to find the population in 2017, while using the given information.

Lets gather the information we should know from the question.

Key information:

2015 -- Population of 750

Increased by 17% in the next year

Decreased by 10% the next year

With the information above, we can solve the problem.

We know that our starting population for crickets is 750, and it increases by 17% for the next year (2016), so we would multiply 750 by 1.17

[tex]750*1.17=877.5[/tex]

Our population in 2016 is 877.5.

Now, we know that he population in 2016 decreased by 10% going into 2017. We would need to find how much of 877.5 is 10%, and then subtract.

[tex]877.5*.10=87.75\\\\877.5-87.75=789.75[/tex]

When you're done solving, you should get 789.75

This means that the population of crickets in 2017 is 789.75.

Now, we know that we started with 750 crickets, now we have 789.5 crickets.

We would divide 789.5 by 750.

[tex]789.5\div750=1.053[/tex]

We would move the decimal place two times to the right, giving us 5.3.

This means that the population increased by 5.3% from 2015 to 2017.

Answer:

Option A. x=30,y=42

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

Triangles ABC and ZYX have three congruent interior angles

therefore

Triangles are similar

step 1

Find the value of x

[tex]\frac{ZY}{AB}=\frac{ZX}{AC}[/tex]

substitute the values

[tex]\frac{20}{x}=\frac{12}{18}[/tex]

[tex]x=20*18/12=30\ units[/tex]

step 2

Find the value of y

[tex]\frac{ZY}{AB}=\frac{XY}{CB}[/tex]

substitute the values

[tex]\frac{20}{30}=\frac{28}{y}[/tex]

[tex]y=30*28/20=42\ units[/tex]

ANSWER

The standard form is:

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

EXPLANATION

The given line passes through (4,10)and (6,11).

The slope of this line is

[tex]m = \frac{11 - 10}{6 - 4} [/tex]

[tex]m = \frac{1}{2} [/tex]

The equation is given by the formula,

[tex]y-y_1=m(x-x_1)[/tex]

We plug in the first point and the slope to get.

[tex]y-10= \frac{1}{2} (x-4)[/tex]

[tex]2y - 20 = x - 4[/tex]

[tex]x - 2y = - 20 + 4[/tex]

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

The standard form is

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

200.96 inch²

Step-by-step explanation:

formula for a circle: (pi) x r²

pi= 3.14

3.14 x 8²

=200.96 inch²

For this case we have by definition, that the area of a circle is given by:

[tex]A = \pi * r ^ 2[/tex]

Where:

A: It is the radius of the circle

They tell us as data that the radius is 8 inches.

Substituting we have:

[tex]A = \pi * (8) ^ 2\\A = \pi * 64\\A = (3.14) (64)\\A = 200.96[/tex]

Thus, the area of the circle is [tex]200.96 \ in ^ 2[/tex]

Give me BRAINLIEST please

let's say the total holdings for the company, or namely the total quantity for the ratios is say hmmm "x", and we were to split "x" in quantities of 27:19:14:11 ratio, what we do is, we simply divide "x" by (27+19+14+11), and then distribute accordingly.

so, if we divide the total amount like that, we end up with fragments of the total, and each ratio gets so many fragments.

so, we know the German stock or that ratio gets $238 millions, and in those 238, since it's on a 14 ratio, there are 14 of those fragments of the total, how much is a fragment anyway?  well, simply how many times does 14 go into 238?  238 ÷ 14 = 17.

well, since we know the whole total of the holdings was split in fragments of 17, let's simply distribute accordingly.

Answer:

[tex]GT=10\ units[/tex]  and [tex]TA=6\ units[/tex]

Step-by-step explanation:

we know that

In the diagram

Triangles GRT and GEA are similar by AA Similarity Postulate

Remember that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

[tex]\frac{GR}{GE}=\frac{GT}{GA}[/tex]

we have

[tex]GR=5\ units[/tex]

[tex]GE=5+3=8\ units[/tex]

[tex]GT=16-x\ units[/tex]

[tex]GA=16\ units[/tex]

substitute

[tex]\frac{5}{8}=\frac{16-x}{16}\\ \\5*16=8*(16-x)\\ \\80=128-8x\\ \\8x=128-80\\ \\x=48/8\\ \\x=6\ units[/tex]

L ----> the length of rectangular movie screen

W ----> the width of rectangular movie screen

we know that

The area is equal to

[tex]A=LW[/tex]

[tex]A=6,699\ ft^{2}[/tex]

so

[tex]6,699=LW[/tex] ----> equation A

[tex]L=W+10[/tex] ----> equation B

substitute equation B in equation A

[tex]6,699=(W+10)W\\ \\W^{2} +10W-6,699=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]W=77\ ft[/tex]

see the attached figure

To find the equation of a line perpendicular to 5x - 2y = -6 and passing through (5, -4), first determine the slope of the given line and then find the negative reciprocal of that slope. Using point-slope form with the new slope and the given point, the equation is y = - (2/5)x - 2.

To find the equation of the line that is perpendicular to the given line 5x - 2y = -6 and passes through the point (5, -4), follow these steps:

Step 1: Find the slope of the given line

Rewrite the given line in slope-intercept form (y = mx + b):

5x - 2y = -6
-2y = -5x - 6
y = (5/2)x + 3

The slope (m) of the given line is 5/2.

Step 2: Find the slope of the perpendicular line

The slope of the line perpendicular to another is the negative reciprocal. Thus, the slope of the perpendicular line is -2/5.

Step 3: Use the point-slope form

Using the point (5, -4) and the slope -2/5 in the point-slope form (y - y1 = m(x - x1)):

y - (-4) = - (2/5)(x - 5)
y + 4 = - (2/5)x + 2
y = - (2/5)x - 2

Therefore, the equation of the line that is perpendicular to 5x - 2y = -6 and passes through the point (5, -4) is y = - (2/5)x - 2.

Answer:

2/5

Step-by-step explanation:

Rise over run

Difference of y over the difference in x

Answer:

The slope is 2/5

Step-by-step explanation:

The slope formula is delta y over delta x.  If you insert the coordinates the equation is 1-3 / 3-8 = -2/-5 = 2/5.  The slope is 2/5

Lines that are parrellell presume to have the same slope.

So if we just calculate the slope of a function or a line we should be good.

[tex]s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Now put in the data from the coordinates of the points [tex]A(3,-1)\wedge B(1,7)[/tex]

[tex]s=\dfrac{7-(-1)}{1-3}=\dfrac{8}{-2}=\underline{-4}[/tex]

The form of a function now looks like: [tex]

f(x)\vee y=-4x+n[/tex]

From here we are no longer required to calculate anything more. Leave n alone.

The solutions are the equations of the form above.

That would mean:

[tex]

y=-4x \\

y=-4x+8 \\

y+1=-4(x+1) \\

y-6=-4(x-3)

[/tex]

Answer:

(1,2)  maximum

Step-by-step explanation:

The vertex is the the point on the graph where the graph does a "u-turn".

this point can either represent the maximum value or the minimum value depending on which way the graph is facing.

In this case, the graph looks like an "n" (as opposed to a "u").

We can clearly see that the point where the graph makes a U-turn is (1, 2)

we can also see that no part of the graph extends above this point, hence this point represents the maximum value which y could possibly be.

Hence (1,2) is maximum

Answer:

So there are 35 quarters and 21 nickels.

Step-by-step explanation:

So I guess that is all we have is quarters and nickels.

Quarters are worth .25

Nickels are worth .05

Let x represent the number of quarters

Let y represent the number of nickels

x+y=56

.25x+.05y=9.8

We are going to solve this system.

I'm going to use substitution. I will solve the first equation for y and then plug that into the second equation.

y=56-x  

.25x+.05(56-x)=9.8

.25x+2.8-.05x=9.8

.20x+2.8=9.8

.2x          = 7

 x=7/(.2) or 7*5=35

y=56-x

y=56-35=21

So there are 35 quarters and 21 nickels.

Answer:

A) n + q = 56

B) .05n + .25q = 9.80

We multiply A) by -.25

A) -.25n -.25q = -14  then add it to equation B)

B) .05n + .25q = 9.80

-.2n = -4.20

nickels = 4.20 / .20 = 21

quarters = 35
