Answer:

3.5

Step-by-step explanation:

pythagorean therom 1.6^2+3^2=x^2

Answer:

x = 3.4

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this:

[tex]a^2+b^2=c^2[/tex]

→The "a," and "b," are the legs, 3 and 1.6, and the "c," is the hypotenuse, which we are trying to find.

[tex]1.6^2+3^2=c^2[/tex]

[tex]2.56 + 9 = c^2[/tex]

→Add like terms (2.56 and 9) together:

[tex]11.56 = c^2[/tex]

→We need to get "c," by itself, and to do this we need to square root both sides, like so:

[tex]\sqrt{11.56} =\sqrt{c^2}[/tex]

[tex]3.4 = c[/tex]

Answer:

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Step-by-step explanation:

Given that Antonina needs to have worked at least 90 volunteer hours to graduate means that she needs to volunteer either for 90 hours or more than that . Mathematically this can be written as

Total volunteer hours required to graduate greater than or equal to 90

Total volunteer hours required to graduate>= 90

No. of hours already volunteered = 52

no. of hours left for volunteering = Total volunteer hours required to graduate - No. of hours already volunteered = 90 - 52 = 38

No. of hours in one week she can dedicate for volunteering= 3

if w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours

then total volunteer hours dedicated in w weeks will be = w*No. of hours in one week she can dedicate for volunteering = w*3 = 3w

Thus,

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Answer:

A

Step-by-step explanation:

Remember that triangle's area is 1/2 x b x h. But we have 2 congruent triangles so we have 2 x 1/2 x b x h. so the area of 2 triangles is b x h.

You should know the areas of other sides.

5 x 6 + 6 x 12 + 6 x 13 + 5 x 12

Answer:

The angle of the shaded region is 124.9°

Step-by-step explanation:

Since there's an region inside the circle that is shaded and has an area of 34 pi square units, we can apply the circle's sector area's formula in order to find the angle of this region. The formula is given by:

[tex]\text{sector area} = \frac{\text{angle}*\pi*r^2}{360}\\[/tex]

Applying the data from the problem gives us:

[tex]34*\pi = \frac{angle*\pi*(7*\sqrt{2})^2}{360}\\34 = \frac{angle*(49*2)}{360}\\98*angle = 34*360\\angle = \frac{12240}{98} = 124.9\°[/tex]

The angle of the shaded region is 124.9°

Answer:

-3/2,collinear.

Step-by-step explanation:

slope of PQ=(0-3)/(2-0)=-3/2

eq. of line PQ is

y-3=-3/2(x-0)

y-3=-3/2 x

or2y-6=-3x

or 3x+2y=6

if R(4,-3) lies on it,then

3(4)+2(-3)=6

12-6=6

or 6=6

which is true.

Hence points P,Q,R are collinear.

Step-by-step explanation:

Answer:

Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.

We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.

Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

Step-by-step explanation:

(x + 6)(7x − 1)

FOIL

first x*7x = 7x^2

outer: -1x

inner: 6*7x = 42x

last: -6

Add them together

7x^2 -x+42x -6

Combine like terms

7x^2 +41x -6

Answer: x-intercept

The x-intercept is the point where a line crosses the x-axis.

All x-intercepts have a y-coordinate of 0.

As an ordered pair, we can write this as (-19.164, 0).

Answer:

Algebraically

0.5x-7= √(-5x+29)

(0.5x-7)² = -5x+29

(0.5x)² - 2*0.5x*7 + 7² = -5x+29

0.25x² - 7x + 49 + 5x - 29 = 0

0.25x² - 2x + 20 = 0

Its discriminant is:

b² - 4*a*c

(-2)² - 4*0.25*20

-16 < 0

Therefore, the equation has no solutions.

Graphically

In the picture attached, the plots of the functions are shown. We can see that they don't intersect each other, and that is why there is no solution.

Answer:

y = - 3x - 4

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 )

y = [tex]\frac{1}{3}[/tex] x - 3 ← is in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{3} }[/tex] = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, - 1) into the partial equation

- 1 = 3 + c ⇒ c = - 1 - 3 = - 4

y = - 3x - 4 ← equation of perpendicular line

Answer:

3:5 Is the ratio because there are five pieces of cheese.

Step-by-step explanation:

If there are 12 pieces, then you can add 4 and 3 together and get 7 and then you can take 7 from 12 and get 5 which is how many cheese pieces there are. Now you know that there are 3 slices of pepperoni and 5 pieces of cheese. Therefore the ratio is 3:5.

Answer:

Both are correct because after substituting the same value into both expressions, the result is the same.

Step-by-step explanation:

Given the expression:

(1/6)*(6*x + 12) - (1/2)*(4*x + 2)

Applying distributive property:

(1/6)*6*x + (1/6)*12 - (1/2)*4*x - (1/2)*2 =

= x + 2 - 2x - 1 =

= -x + 1

Then, for any number substituted into both equations, the result is the same
