A right triangle has one angle that mesures 23. The adjacent leg measures 27.6 cm and the hypotenuse measures 30cm.

What is the approximate area of triangle? Round to the nearest tenth

Area of the triangle =1/2bh

A:68.7cm^2
B.161.7cm^2
c.381.3cm^2
D450.cm^2

Answers

you can start by finding the height or altitude ("alt" = vertical side touching hypotenuse and bottom base):
tangent (23) = opposite/adjacent (TOA), where opposite is altitude and adjacent is base
So tangent (23) = alt/27.6cm
alt = 27.6×tan23 = 27.6×0.424
alt = 11.72cm
So now area = 1/2 (b)(h), where h=alt
area = 1/2 (27.6cm)(11.72cm) = 161.7cm^2
[tex] 161.7{cm}^{2} [/tex]
So the correct answer is [B.]

If EG=25 and point F is 2/5 of the way between E and G, find the value FG. The drawing is not to scale.

a. 12.5
b. 10
c. 20
d. 15
d. 7

Answers

First find 2/5 of 25.
This can be done by multiplying the two numbers.
2/5 × 25 = 10

10 is the distance from E to F.
So now that you have EF and know the overall length of EG (25), you can easily find FG.
25 - 10 = 15

The answer is:
d. 15

Solve for x: −3 |x + 7| = −12

Answers

[tex]-3|x + 7|=-12\quad |:(-3)\\\\|x+7|=4\\\\\\x+7=-4\qquad\vee\qquad x+7=4\\\\x=-4-7\qquad\vee\qquad x=4-7\\\\\boxed{x=-11\qquad\vee\qquad x=-3}[/tex]
first you divide both sides by -3
then you get |x + 7| = 4
what you do now is make two separate equations
drop the absolute value signs
x + 7 = 4 OR x + 7 = -4
subtract 7 from both sides AND BOTH EQUATIONS
x = -3 OR x = -11

lets check it!

-3 |-3 + 7| = -12                           -3 |-11 + 7| = -12
-3 |4| = -12                                  -3 |-4| = -12
-3 (4) = -12                                  -3 (4) = -12

yep! your answers are x = -3 OR x = -11

A bouncing ball reaches a height of 27 feet at its first peak, 18 feet at its second peak, and 12 feet at its third peak. Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak.

Answers

Hey there!

A= value of the first term
n= the number of the term you want to find
r= common ratio
 value of r is = 2/3 because 27 times 2/3 = 18 which is the second term
n = 4 since you want to find the 4th term in the sequence
Plug it in and results are
4th term = 27(2/3)^(4-1)  = 8
The answer is 8


Hope this helps!
A sequence can be used to illustrate the difference in heights of each jump and develop a pattern from them. In this case, we have 27, 18, 12,... Assuming the pattern continues, we have the previous height divided by 3 and then subtracted from itself:

Square tiles 9-inches on a side cover the floor of a rectangular room exactly. the border tiles are white and all other tiles are blue. the room measures 18 feet by 15 feet. how many tiles are white

Answers

first convert feet to inches:
18 ft × (12in/1ft)= 216 in
15 ft × (12 in/1ft)= 180 in

divide each side of the room by 9 inches to get number of white tiles per a wall

wall 1(18ft): 216in/9in= 24 white tiles
wall 2(15ft): 180in/9in= 20 white tiles
wall 3(18ft): 216in/9in= 24 white tiles
wall 4(15ft): 180in/9in= 20 white tiles


Lastly, add up all the white tiles and subtract 4 (the tiles that we counted twice because they were the corner tiles and touched both walls)

24+20+24+20-4= 84 white tiles total

When matter changes state, what two things are always conserved?

Answers

Even though matter changes state, there are two things which are always conserved: they are mass and chemical composition. Just because the state has changed, it does not mean that any new molecules are either created or have been destroyed. The Law of Conservation of mass explains this concept.

In a change of state, mass and energy are the two things that are always conserved, in accordance with the law of conservation of matter and the first law of thermodynamics, respectively.

When matter changes state, the two things that are always conserved are mass and energy. This is explained by the law of conservation of matter, which states that the total mass of the products must equal the total mass of the reactants in a chemical reaction, and the law of conservation of energy, often referred to as the first law of thermodynamics.

In any given closed system, neither mass nor energy is created or destroyed, but can be transformed from one form to another. For example, when a substance burns, its matter is not lost but is instead transformed into other substances with the same total mass. Likewise, energy can be moved or transformed, but the total amount of energy remains constant. These principles apply to both living and non-living systems, keeping the total quantity of matter and energy fixed in the universe.

The length of a rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 3 cm/s. when the length is 20 cm and the width is 10cm, how fast is the area of the rectangle increasing

Answers

Let l = length of the rectangle,
b = breadth of the rectangle,
a = area of the rectangle,
t = time,

So, [tex] \frac{dl}{dt} [/tex] = 8 cm/s &
[tex] \frac{dw}{dt} [/tex] = 3 cm/s

Area of the rectangle, a = l × w

Differentiate the equation with respect to t,

[tex] \frac{da}{dt} [/tex] = l × [tex] \frac{dw}{dt} [/tex] +  w × [tex] \frac{dl}{dt} [/tex]

[tex] \frac{da}{dt} [/tex] = 20 × 3 +  10 × 8

[tex] \frac{da}{dt} [/tex] = 60 +  80

[tex] \frac{da}{dt} [/tex] = 140 [tex] cm^{2} [/tex]/s

Therefore, the correct answer is 140 [tex] cm^{2} [/tex]/s.
The information that is given:
dl/dt = 8  (rate of length increasing)
dw/dt = 3 (rate of width increasing)
l = 20 (when the length is 20)
w = 10 (when the width is 10)

The unknown is dA/dt (the rate the area is increasing)

Start with the formula for the area of a rectangle
A = w*l
Find the derivative of it
d/dt(A) = d/dt(w*l)  Use the multiplication rule
dA/dt = w(dl/dt) + l(dw/dt) 
Substitute in what is known from above
dA/dt = 10(8) + 20(3) = 80+60 = 140
The area is increasing 140 square centimeters per second

*Recall that Volume = (Length)(Width)(Height)

Part 2: Write an expression that represents the dimensions of the large box.

Part 3: What is the difference in the volumes of the two boxes? Show or explain or work.

I ended up finding the first 2
vsmall=x(x+2)(2x)
vlarge=(x+5)(x+7)(3x)
I found those on answers . com
V=volume...
I just need #3

1. The expression that represents the dimensions of the small box is (2x³ + 4x²).

2. The expression that represents the dimensions of the large box is (3x³ + 36x² + 105x).

3. The difference in the volumes of the two boxes is (x³ + 32x² + 105x)

What is the volume of the box?

1.

Small box:

x inches,

(x+ 2) inches and

(2x) inches

Volume = length × width × height

= x × (x + 2) × (2x)

= (x² + 2x) × 2x

= 2x³ + 4x²

2.

Large box:

(x+5) inches,

(x + 7) inches and

(3x) inches.

Volume = length × width × height

= (x + 5) × (x + 7) × (3x)

= 3x³ + 36x² + 105x

4.

Difference in volume = Large box - Small box

= (3x³ + 36x² + 105x) - (2x³ + 4x²)

= 3x³ + 36x² + 105x - 2x³ - 4x²

= x³ + 32x² + 105x

Therefore, x³ + 32x² + 105x is the expression which represents the volume of the box.

Billie and Toni are driving from Chicago to Phoenix. The first day they drove 420 miles. They want to drive at 65 miles per hour for the rest of their trip. a. Write an algebraic expression to represent the situation. b. If they drive 8 hours a day for the next two days, how far have they traveled by the end of the third day?

Answers

A. We are given that they already drove 420 miles and an additional of 65 miles per hour. Therefore distance covered is:

d = 420 + 65 t

where d is distance and t is time

 

B. If they drove 8 hours per day for 2 days, then total time is t = 16 hours, hence:

d = 420 + 65 * 16

stella writes 1/7 of a page in 1/5 of a minute. how many minutes doesn’t it take her to write a full page?

Answers

It takes Stella 1.4 minutes to write a full page, calculated by setting up a proportion based on her rate of writing [tex]\frac{1}{7}[/tex] of a page in 1/5 of a minute.

Stella writes  [tex]\frac{1}{7}[/tex] of a page in  [tex]\frac{1}{5}[/tex] of a minute. To calculate how many minutes it takes her to write a full page, we can set up a proportion. Since 7/7 would make a full page, we'd need Stella to write seven times as much as she does in 1/5 of a minute. So, the math to find the time for a full page looks like this:

[tex]\frac{1}{7}[/tex] page :  [tex]\frac{1}{5}[/tex]  minute = 7/7 page : x minutes

Now multiply both sides by (1/5) minutes to isolate x:

[tex]\frac{1}{7}[/tex] /   [tex]\frac{1}{5}[/tex] = 1/x

Cross multiply to solve for x:

[tex]\frac{1}{7}[/tex] * x =  [tex]\frac{1}{5}[/tex]

x =  [tex]\frac{1}{5}[/tex]  /  [tex]\frac{1}{7}[/tex]

x =  [tex]\frac{1}{5}[/tex]  * (7/1)

x = 7/5 minutes

x = 1.4 minutes

Therefore, it takes Stella 1.4 minutes to write a full page.
