Step-by-step explanation:
There are 3 triangles in the picture: the one on the left, the one on the right, and the overall triangle. We must first find the areas of the two smaller triangles before finding the area of the whole thing.
To find the area of a triangle, you must multiply the two legs of the triangle by each other and then divide that number by 2. For the left triangle, this would be [tex](4*4)/2=8[/tex], meaning it has an area of 8 square meters. For the right triangle, this would be [tex](4*3)/2=6[/tex], meaning the triangle on the right has an area of 6 square meters.
There are multiple ways to find the area of the big triangle, since the hypotenuse of the left triangle has been rounded. One way to find the area of the big triangle,is to add the areas of the two smaller triangles: [tex]8+6=14[/tex] square meters. For a more exact answer, we would solve [tex](5.7*5)/2=14.25[/tex]sqaure meters using the legs of the big triangle.
Hope this helps! :)

Answers
Answer: $400 was invested
Step-by-step explanation: Based on the scenario in the question, our calculation goes thus:0.11x + 0.06(8000 - x) = 5000.11x + 480 - 0.06x = 5000.11x - 0.06x = 500 - 4800.05x = 20x = 20/0.05x = 400

Weekly wages at a certain factory are
normally distributed with a mean of
of
$400 and a standard deviation of $50.
Find the probability that a worker
selected at random makesbetween
$400 and $450.
[? ]%
Answers
Answer:
The probability that a worker makes between $400 and $450 is .3413 using the calculator and .34 using the empirical rule.
Step-by-step explanation:
There are two ways to approach this problem.
The first way is to find the z-score corresponding to $400 and $450 weekly wage and find the p-value in between these values.
[tex]\displaystyle \frac{400-400}{50} < z < \frac{450-400}{50}[/tex][tex]\displaystyle 0 < z < 1[/tex]
If you use the normalcdf function on your calculator and put 0 and 1 as the lower and upper bounds, respectively, you will get an area of .3413.
Another way of looking at this problem is to recognize that the weekly wages given are the mean and one standard deviation above the mean.
We can use the Empirical Rule, 68-95-99.7, in order to see that going one standard deviation above the mean would be an area of 68/2 = .34.
I've attached an image that shows you what the normal curve looks like.

Answers
Answer:
87.92 mm²
Step-by-step explanation:
Given:
Radius of circular base: 2 millimetersHeight of cylinder: 5 millimetersIt should be noted:
Surface area of cylinder: 2πrh + 2πr² (R = Radius; H = Height)When the measures are substituted, we get the following expression:
⇒ 2π(2)(5) + 2π(2)²Multiply the constants and substitute π as 3.14.
⇒ 20π + 2π(4)⇒ 20π + 8π⇒ 20(3.14) + 8(3.14)Finally, simplify the expression to determine the surface area.
⇒ 20(3.14) + 8(3.14)⇒ 62.8 + 25.12⇒ 87.92 mm²Answer:
88.0 mm² (nearest tenth)

Mira buys a telescope that costs $180. She has to pay 4% sales tax. how much will she pay in all
Answers
Mira would pay $187.2
What is the formula for tax rate?"Tax rate = (Tax amount / Price before tax) × 100% "
What is the formula for tax amount?"Tax amount = Final price - Price before tax"
For given question,
Mira buys a telescope that costs $180.
⇒ Price before tax = $180
sales tax = 4%
Let 'm' be the tax amount.
Using the formula of tax rate,
⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%
⇒ 4% = ([tex]\frac{m}{180}[/tex]) × 100%
⇒ 0.04 × 180 = m
⇒ m = 7.2
Using the formula for the tax amount,
⇒ Tax amount = Final price - Price before tax
⇒ Final price = Tax amount + Price before tax
⇒ Final price = 7.2 + 180
⇒ Final price = $187.2
Therefore, Mira would pay $187.2

A piece of wire 19 m long is cut into two pieces. One piece is bent into a square and the other is bent into an equilateral triangle.
How much wire should be used for the square in order to minimize the total area?
Answers
Answer: 8.26 m
Step-by-step explanation:
[tex]$$Let s be the length of the wire used for the square. \\Let $t$ be the length of the wire used for the triangle. \\Let $A_{S}$ be the area of the square. \\Let ${A}_{T}}$ be the area of the triangle. \\One side of the square is $\frac{s}{4}$ \\Therefore,we know that,$$A_{S}=\left(\frac{s}{4}\right)^{2}=\frac{s^{2}}{16}$$[/tex]
[tex]$$The formula for the area of an equilateral triangle is, $A=\frac{\sqrt{3}}{4} a^{2}$ where $a$ is the length of one side,And one side of our triangle is $\frac{t}{3}$So,We know that,$$A_{T}=\frac{\sqrt{3}}{4}\left(\frac{t}{3}\right)^{2}$$We have to find the value of "s" such that,$\mathrm{s}+\mathrm{t}=19$ hence, $\mathrm{t}=19-\mathrm{s}$And$$A_{S}+A_{T}=A_{S+T}$$[/tex]
[tex]$$Therefore,$$\begin{aligned}&A_{T}=\frac{\sqrt{3}}{4}\left(\frac{(19-s)}{3}\right)^{2}=\frac{\sqrt{3}(19-s)^{2}}{36} \\&A_{T+S}=\frac{s^{2}}{16}+\frac{\sqrt{3}(19-s)^{2}}{36}\end{aligned}[/tex]
[tex]$$Differentiating the above equation with respect to s we get,$$A^{\prime}{ }_{T+S}=\frac{s}{8}-\frac{\sqrt{3}(19-s)}{18}$$Now we solve $A_{S+T}^{\prime}=0$$$\begin{aligned}&\Rightarrow \frac{s}{8}-\frac{\sqrt{3}(19-s)}{18}=0 \\&\Rightarrow \frac{s}{8}=\frac{\sqrt{3}(19-s)}{18}\end{aligned}$$Cross multiply,$$\begin{aligned}&18 s=8 \sqrt{3}(19-s) \\&18 s=152 \sqrt{3}-8 \sqrt{3} s \\&(18+8 \sqrt{3}) s=152 \sqrt{3} \\&s=\frac{152 \sqrt{3}}{(18+8 \sqrt{3})} \approx 8.26\end{aligned}$$[/tex]
[tex]$$The domain of $s$ is $[0,19]$.So the endpoints are 0 and 19$$\begin{aligned}&A_{T+S}(0)=\frac{0^{2}}{16}+\frac{\sqrt{3}(19-0)^{2}}{36} \approx 17.36 \\&A_{T+S}(8.26)=\frac{8.26^{2}}{16}+\frac{\sqrt{3}(19-8.26)^{2}}{36} \approx 9.81 \\&A_{T+S}(19)=\frac{19^{2}}{16}+\frac{\sqrt{3}(19-19)^{2}}{36}=22.56\end{aligned}$$[/tex]
[tex]$$Therefore, for the minimum area, $8.26 \mathrm{~m}$ should be used for the square[/tex]

Because there are many different ways to teach introductory astronomy, we have made the text as flexible as we could. Math examples are shown in separate sections throughout, so that you can leave out the math or require it as you deem best. Each section of a chapter treats a different aspect of the topic being covered; a number of sections could be omitted in shorter overview courses and can be included where you need more depth. And, as we have already discussed, you can customize the book in a variety of ways that have never been possible in traditional textbooks.
Step-by-step explanation:
This book is written to help students understand the big picture rather than get lost in random factoids to memorize. The language is accessible and inviting. Helpful diagrams and summary tables review and encapsulate the ideas being covered. Each chapter contains interactive group activities you can assign to help students work in teams and pool their knowledge.

6. A gas tank holds 450 gal. when it is filled to the height of 12 ft. How many
gallons will it hold when it is filled to 5 ft.?
Answers
Answer:
[tex]\huge\boxed{\sf 187.5\ gal.}[/tex]
Step-by-step explanation:
Given that:
For,
12 ft. height, gas tank can hold 450 gal.
Using unitary method:
12 ft = 450 gal.
Divide 12 to both sides
1 ft = 450/12 gal.
1 ft = 37.5 gal.
Multiply 5 to both sides
5 ft. = 37.5 × 5 gal.
5 ft. = 187.5 gal.
So, the height of 5 ft. holds 187.5 gal.
[tex]\rule[225]{225}{2}[/tex]
Answer:
