Answer:105
Step-by-step explanation:
area of rectangle (b*h) (7*12)
Area of triangle 1/2 (b*h) 1/2(7*6)
Rectangle=84
Triangle=21
84+42= 105
Answer:
105
Step-by-step explanation:
Well, this figure, as you can see, is made of two figures - a triangle and a rectangle.
To find it's area we will find the areas of the triangle and the rectangle separately and then sum them. I hope you get why we do that.
So, let's start with the rectangle.
The area of the rectangle is very easy to find simply just multiply the lenghts of its two sides:
A1 = 7 * 12 = 84
Now, the triangle.
You can see that one of the smaller sides of the rectangle is equal to 7. The side in front of it is also 7. Notice that this side is also equal to one of the sides of the triangle, its base.
So from the figure we can tell that the base of the triangle is equal to 7, we are also given its height.
There is a formula we can use here to find the area. The area of a triangle is equal to its base (a) multiplied by the height(h) and divided by 2. I'll call the area of the triangle A2.
We know the height
h = 6
I hope you noticed that we also know the base
a = 7
So we just use the formula:
A2 = (6 * 7) / 2 = 42 / 2 = 21
Now that we have the areas of the two figures, A1 and A2, all we have to do is to sum them to find the area of the big one.
So, let's do it:
A = A1 + A2
A = 84 + 21 = 105
a+b×2%

An investor buys in a company and in the twelve months after she invests the value of the stock decreases by 30% , bu what amount will the value of the stock need to go up from there in order that the price of the stock will be equal to what the investor first paid for it ?
a:30%
b:37,5%
c:42. 9
d:45
e:46. 7
Answer:
B 37.5%
Step-by-step explanation:
If the ball leaves her hand 6 feet above the ground at 65 feet/second: a) what is the maximum height of the ball
[tex]~~~~~~\textit{initial velocity in feet} \\\\ h(t) = -16t^2+v_ot+h_o \quad \begin{cases} v_o=\textit{initial velocity}&65\\ \qquad \textit{of the object}\\ h_o=\textit{initial height}&6\\ \qquad \textit{of the object}\\ h=\textit{object's height}&\\ \qquad \textit{at "t" seconds} \end{cases} \\\\\\ h(t)=-16t^2+65t+6[/tex]
Check the picture below, the maximum occurs at the vertex of the parabolic path, so
[tex]\textit{vertex of a vertical parabola, using coefficients} \\\\ h(t)=\stackrel{\stackrel{a}{\downarrow }}{-16}t^2\stackrel{\stackrel{b}{\downarrow }}{+65}t\stackrel{\stackrel{c}{\downarrow }}{+6} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right)[/tex]
[tex]\left(-\cfrac{ 65}{2(-16)}~~~~ ,~~~~ 6-\cfrac{ (65)^2}{4(-16)}\right)\implies \left(\cfrac{65}{32}~~,~~6+\cfrac{4225}{32} \right) \\\\\\ \left(\cfrac{65}{32}~~,~~\cfrac{4609}{32} \right) \implies \stackrel{maximum~height}{(2.03125~~,~~\stackrel{\downarrow }{72.015625})}[/tex]
Find the 6th term of the arithmetic sequence X – 9, -X – 11, -3.3 – 13, ...
Answer:
[tex]-13x-23[/tex]
Step-by-step explanation:
Given sequence: [tex]x-9, -x-11, -3x-13[/tex]
Therefore,
[tex]a_1=x-9[/tex][tex]a_2=-x-11[/tex][tex]a_3=-3x-13[/tex]General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]
(where a is the first term and d is the common difference)
To find the common difference, subtract a term from the next term:
[tex]\begin{aligned}d & =a_2-a_1\\ & =(-x-11)-(x-9)\\ & = -x-11-x+9\\ & = -2x-2\end{aligned}[/tex]
Therefore,
[tex]a_n & =(x-9)+(n-1)(-2x-2)[/tex]
To find the 6th term, input n = 6 into the equation:
[tex]\begin{aligned}\implies a_6 & =(x-9)+(6-1)(-2x-2)\\ & = (x-9)+7(-2x-2)\\ & = x-9-14x-14\\ & = -13x-23\end{aligned}[/tex]

Please find the area and circumference of the circle with diameter 3.7cm
Answer:
Area: 10.7521 cm
Circumference: 11.62389 cm
________________________________________________________
Solve: AreaArea, A, will equal the formula of [tex]\pi r^2[/tex], so we must find the value and split that up. Diameter, d is equal to 2r. Let's solve.
[tex]A = \pi r^2[/tex]
[tex]d = 2r[/tex]
Now, make an equation combining like terms.
[tex]A = \frac{1}{4} \pi d^2[/tex]
This equation means to multiply those terms together. Since the diameter is 3.7, d is 3.7
[tex]\frac{1}{4} * \pi * 3.7 = 10.8(estimate)~cm[/tex]
Let's move on to circumference. On we go!
________________________________________________________
Solve: CircumferenceWith circumference, it is very similar to what you just did to find area(A). You must again, set up these terms and make an equation out of them. C(circumference) is going to be equal to [tex]\pi r[/tex], notice how it does not say squared([tex]^2[/tex]) at the end now.
[tex]C = \pi r[/tex]
And diameter, you guessed it, will be 2r.
[tex]d = 2r[/tex]
Now, combine the like terms into an equation.
[tex]C = \pi d[/tex] pi times diameter(3.7)
[tex]\pi * d(3.7) = 11.6~cm[/tex]
Now that the problem is done, we move on to review.

What have we learned?We learned how to solve for circumference and area using diameter.

The vertical of three squares are joined to form a right triangle , what is the area of the largest square
A- 25cm^2
B- 202,500cm^2
C- 34cm^2
D- 43cm^2
Answer:
43cm²
Step-by-step explanation:
let's first consider the area of a square.
the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.
so to find the side of the square using the area, we take the square root of both of the area.
[tex] \sqrt{25} = 5[/tex]
and also
[tex] \sqrt{18} = 4.2[/tex]
so we have the height of the triangle as 5cm and the base is 4.2cm.
now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.
[tex] \sqrt{ {5}^{2} + {4.2}^{2} } = 6.53cm[/tex]
so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula
Area = L²
Area = 6.53²
Area = 42.6cm
the nearest cm square
Area = 43cm²
