Answer:

X=119

Z=28

Step-by-step explanation:

5z-79=61

Solve for x:

A straight line is 180 so...

180-61=119

Solve for z:

5z=61+79

5z=140

Z=140/5

Z=28

Sorry for who ever uploaded the disturbing photos :(

Hope this help and have a nice day!

MATH HELP PLEASE! I NEED HELP IM DUMB
deff fn [24]

First of all...YOU'RE NOT DUMB!!! You just need some help! Being confident in your knowledge/skills is half the work! ;D

And second...

PART 1:

28. Polygon ABCDE is a pentagon (it has five sides). The sum of the interior angle measures for a pentagon is 540°. Here's what we know:

m<A = 90°

m<B = 90°

m<D = 90°

m<C = m<E

First, find the sum of the measures of angles A, B, and D.

(90)(3) = 270°.

Next, find the combined angle measure of angles C and E.

540 - 270 = 270°.

Finally, find the measure of angle E (or m<AED).

270 / 2 = 135°.

So, to fill in the blanks:

90 · 3 + x · 2 = 540

m<AED = 135°.

29.

(a) 360°

(b) hexagon

(c) 1080

(d) hendecagon (11 sides)

I have attached a table containing a list of polygons, their side-count, and the sum of their interior angles.

PART 2:

Complimentary angles are angles whose measures add to equal 90°.

Supplementary angles are angles whose measures add to equal 180°.

30. 35° + 55° = 90°; Complimentary.

31. 62° + 108° = 170°; Neither.

Hope this helps!

7-18 use part 1 of the fundamental theorem of calculus to find the derivative of the function.
blondinia [14]

\displaystyle h(x)=\int\limits_{1}^{\sqrt{x}}~\cfrac{z^2}{z^4+1}dz~\hspace{10em}\cfrac{dh}{du}\cdot \stackrel{chain~rule}{\cfrac{du}{dx}\implies \cfrac{dh}{dx}} \\\\[-0.35em] ~\dotfill\\\\ u=\sqrt{x}\implies \cfrac{du}{dx}=\cfrac{1}{2\sqrt{x}} \\\\[-0.35em] ~\dotfill

\cfrac{dh}{dx}\implies \displaystyle \cfrac{d}{du}\left[ \int\limits_{1}^{u}~\cfrac{z^2}{z^4+1}dz \right]\cdot \cfrac{1}{2\sqrt{x}}\implies \left[ \cfrac{u^2}{u^4+1} \right]\cdot \cfrac{1}{2\sqrt{x}} \\\\\\ \stackrel{substituting~back}{\left[ \cfrac{(\sqrt{x})^2}{(\sqrt{x})^4+1} \right]\cdot \cfrac{1}{2\sqrt{x}}}\implies \cfrac{x}{x^2+1}\cdot \cfrac{1}{2\sqrt{x}}\implies \cfrac{\sqrt{x}}{2x^2+2}

Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per
horrorfan [7]

The speed of slower car is 45 mph and faster car is 50 mph.

Step-by-step explanation:

Given,

Distance covered by both cars = 190 miles

Time taken by both of them = 2 hours

Let,

x be the speed of slower car.

Speed of faster car = x+5

Combined speed = x+x+5 = 2x+5

We know that;

Distance = Speed * Time

190=(2x+5)*2\\190=4x+10\\4x=190-10\\4x=180\\

Dividing both sides by 4

\frac{4x}{4}=\frac{180}{4}\\x=45

Speed of slower car = 45 miles per hour

Speed of faster car = 45+5 = 50 miles per hour

The speed of slower car is 45 mph and faster car is 50 mph.

Keywords: speed, distance
