Answer:
A = 15 units²
Step-by-step explanation:
the area (A) of the shaded triangle is calculated as
A = area of rectangle enclosing the triangle - area of white triangles on either side of shaded triangle and the one on top
area of rectangle = 10 × 5 = 50 units²
area of 2 congruent triangles = 2 × [tex]\frac{1}{2}[/tex] × 5 × 5 = 5 × 5 = 25 units²
area of top triangle = [tex]\frac{1}{2}[/tex] × 10 × 2 = 5× 2 = 10 units²
A = 50 - 25 - 10= 15 units²

It takes 107 pounds of seed to completely plant an 11 acre field
How many acres can be planted per pound of seed
Answer:
0.103 acres
Step-by-step explanation:
This question tests on the concept of Conversion.
Given from the question, we know that:
107 pounds of seed = 11 acre field
To find the acres of field we can plant per pound of seed, we simply divide both sides of the equation by 107.
(107 ÷ 107) pounds of seed = (11 ÷ 107) acres of fiels
1 pound of seed = 0.103 acres of field (Rounded off to 3 significant figures)
a rope 18M and 50Cm is to be divided into four equal parts. how long will each part be? give your answer in metres and centimetres
Answer:
4 m and 62.5 cm
Step-by-step explanation:
1 meter = 100 cm
So 18m and 50 cm = 18 x 100 + 50 cm = 1850 cm
If it is going to be divided into 4 equal parts, each part = 1850/4 = 462.5 cm
462.5 cm = 462.5/ 100 = 4 m and 0.625 m
0.625m = 0.625 x 100 = 62.5 cm
So each piece is 4 m and 62.5 cm
cual es el volumen de una pila que mide 100 cm de ancho por 110 de largo por 130 cm de alto
The volume of the pile based on the width, height, and length of the pile can be found to be 1.43 m³
How to find the volume?The volume of the pile can be found by the formula:
= Length x Width x Height
From the question, the dimensions of the pile are:
Length = 110 cm
Width = 100 cm
Height = 130 cm
The volume is:
= 110 x 100 x 130
= 1,430,000 cm³
Converted to meters gives:
= 1,430,000 / 1,000,000
= 1.43 m³
In conclusion, the volume in meters of the pile is 1.43 m³

A $100 sweatshirt is put on sale for 40% off. One week later, the sale price is marked up by 40%. Will the marked-up price of the sweatshirt be less than, greater than, or equal to the initial price of $100?
The new price after being marked up is less than initial price of $100.
The price of sweatshirt after discount = 100 - 40%×100
Converting percentage to fraction
The price of sweatshirt after discount = 100 - (40/100)×100
The price of sweatshirt after discount = 100 - 40
Performing subtraction
The price of sweatshirt after discount = $60
The marked up sale price = 60 + 40%×60
Converting percentage to fraction
The marked up sale price = 60 + (40/100)×60
Cancelling zero and performing multiplication
The marked up sale price = 60 + 24
Performing addition
The marked up sale price = $84
Thus, the marked up price after discount will be less than the initial price of $100.

if the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, would this change the value of p(odd number)? explain.
if the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, No , it does not change the value of p(odd number) .
a) The sample space is the set of all possible outcomes. By definition, the elements of a set should not be repeated. Hence, the sample space S = {1, 2, 3}
However, the sample is not equiprobable because each element has different probabilities.
b) P(odd number) = number of odd digits / number of faces = 4/6=2/3
Note that the odd numbers are 1 (on three faces) and 3 (on one face).
c) The fact the die has been biased does not change the possible outcomes. It only changes the probability of getting any given number.
d) Because the 3-face has been loaded, this probability changes. In fact, it is calculated thus:
Let's assume the probability for 1 or 2 is . Then that of 3 is (because it is twice the others). The sum of probabilities must be 1.
x+x+x+x+x+2x=1

an elliptical arch is constructed which is 6 feet wide at the base and 9 feet tall in the middle. find the height of the arch exactly 1 foot in from the base of the arch.
The height of the arch is about 6.71 feet when measured from its base at a distance of one foot.
This is further explained below.
What is an ellipse?Generally, An ellipse is a collection of points whose distances from a fixed point (focus) or fixed line (directrix) is constant and less than 1.
Depending on whether the transverse axis is horizontal or vertical, we may construct an equation for the ellipse. The main axis is located along the transverse axis. The ellipse may be represented using the following equations:
[tex]\begin{aligned}&\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 \\&\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1\end{aligned}[/tex]
An elliptical arch is described as having a center height of 9 feet and a width of 6 feet. The precise height of the arch from the base has to be determined.
[tex]\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1[/tex]
The center (h, k) is where the graph is since we centered it at the origin (0,0). We only need to enter the numbers into the equation at this point.
[tex]\begin{aligned}\frac{(y-0)^2}{9^2}+\frac{(x-0)^2}{3^2} &=1 \\\frac{y^2}{81}+\frac{x^2}{9} &=1\end{aligned}[/tex]
Since we divided the arch in half, 0 [tex]\leq[/tex] 9 in this instance. All that is left to do is calculate the arch's height in feet from the base.
The height of 1 foot from each end of the arch must thus be determined. The locations of the arch's ends are x=-3 and x=3. Here, we have a choice between the two. We may choose x=3-1=2 for this. Therefore, all that is left to do is enter x=2 in our usual form and work out the value of y that results.
[tex]\frac{y^2}{81}+\frac{(2)^2}{9}=1[/tex]
y^2+36=81
y^2+36-36=81-36
y=3√5
Therefore, the height of the arch at 1ft from the base is 3 √5ft or approximately 6.71ft

To pay for a home improvement project that totals $16,000, Genesis is choosing between taking out a simple interest bank loan at 8% for 3 years or paying with a credit card that compounds monthly at an annual rate of 15% for 7 years. Which plan would give Genesis the lowest monthly payment?
well, let's first check with the Bank
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$16000\\ r=rate\to 8\%\to \frac{8}{100}\dotfill &0.08\\ t=years\dotfill &3 \end{cases} \\\\\\ A=16000[1+(0.08)(3)] \implies A = 19840~\hfill \underset{monthly~payment}{\stackrel{19840~\div \stackrel{months}{36}}{\approx \text{\LARGE 551.11}}}[/tex]
now let's check with the Credit Card
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$16000\\ r=rate\to 15\%\to \frac{15}{100}\dotfill &0.15\\ n= \begin{array}{llll} \textit{times it compounds per year} \end{array}\dotfill &12\\ t=years\dotfill &7 \end{cases}[/tex]
[tex]A=16000\left(1+\frac{0.15}{12}\right)^{12\cdot 7} \implies A \approx 45425.81~\hfill \underset{monthly~payment}{\stackrel{45425.81~\div \stackrel{months}{84}}{\approx\text{\LARGE 540.78}}}[/tex]
well, seems the Credit Card is the better deal monthly wise, though in the long run is a lot of dough.
A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.
What is simple interest?Mathematically, the simple interest earned can be calculated by using this formula:
A = P(1 + rt)
Where: A represents the future value.
P represents the principal or original value.
r represents the interest rate.
t represents the time.
Now Substituting the given parameters into the formula, we have,
A = 9000[1 + (0.09 × 3)]
A = 9000[1 + 0.27]
A = 9000 × 1.27
Future value, A = $11,430.
Next, we will calculate the monthly payment over a period of 36 months as follows:
Monthly payment = Future value/Time
Monthly payment = 11,430/36
Monthly payment = $317.50.
Similarly, we will calculate the compound interest earned on the credit card :
A = 9000[1 + (0.18/12)]⁽¹² ˣ ⁷⁾
A = 9000[1 + 0.015]⁸⁴
A = 9000 × 1.015⁸⁴
A = 9000 × 3.49258954
Future value, A = $31,433.31.
Next, we will calculate the monthly payment over a period of 84 months as follows;
Monthly payment = Future value/Time
Monthly payment = 31,433.31/84
Monthly payment = $372.21.
In this context, A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.

The population mean is given by
ц = [tex]\frac{L+U}{2}[/tex]
where L and U are the two given boundaries
Here, L = 1.9 and U = 2.1
