a $2.00
Step-by-step explanation:
0.50 x 4 = 2
If he bought 4 times as many, then take the price times 4.
Answer:
$2.00
Step-by-step explanation:
Stephen bought 1 package for $0.50. His brother bought 4 times as many (4 * 1 packages). Which means his brother bought 4 packages.
If each package costs $0.50 then we simply multiply the price with the amount of packages he bought:
4 * $0.50. Lets get rid of the dollar sign, so it doesn't distract us.
I'm not sure if you studied about floating point numbers yet, but I assume you did.
4 * 0.50 =?
We have two numbers after the floating point, but for the sake of simplicity we can get rid of it too and just multiply 4 * 50 and then put the floating point back into the number after the first two digits (because we removed it after two digits 0.50)
Anyway 4 * 50 = 200
We add the floating point and get:
2.00
Therefore his brother spent $2.00 after we add the dollar sign back in

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
Check the picture below.
How can I solve this trig identity manipulating tan instead of the right side?
Answer:
Trig identities
[tex]\tan(\theta)=\dfrac{\sin(\theta)}{\cos(\theta)}[/tex]
[tex]\sin(\thet2\theta)=2 \sin(\theta)\cos(\theta)[/tex]
[tex]\begin{aligned}\cos(\thet2\theta) & =1-2\sin^2(\theta)\\2\sin^2(\theta) & = 1-\cos(2\theta) \end{aligned}[/tex]
Solution
[tex]\tan(\theta)=\dfrac{\sin(\theta)}{\cos(\theta)}[/tex]
[tex]\textsf{Multiply by}\:\dfrac{2\sin(\theta)}{2\sin(\theta)}:[/tex]
[tex]\begin{aligned}\implies \tan(\theta) & =\dfrac{\sin(\theta)}{\cos(\theta)} \times \dfrac{2\sin(\theta)}{2\sin(\theta)}\\\\ & =\dfrac{2\sin^2(\theta)}{2\sin(\theta)\cos(\theta)}\\\\ & = \dfrac{1-\cos(2\theta)}{\sin(2\theta)}\end{aligned}[/tex]
Therefore,
[tex]\implies \dfrac{1-\cos(2\theta)}{\sin(2\theta)}=\dfrac{1-\cos(2\theta)}{\sin(2\theta)}[/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.

A small country emits 93,000 kilotons of carbon dioxide per year. In a recent global agreement, the country agreed to cut its carbon emissions by 4% per year for the next 10 years. In the first year of the agreement, the country will keep its emissions at 93,000 kilotons and the emissions will decrease 4% in each successive year. How many total kilotons of carbon dioxide would the country emit over the course of the 10 year period, to the nearest whole number?
Answer:
779264 k-tons
Step-by-step explanation:
First year ====> no change
then each of the next 9 years decrease by 4 % ( leaving 96%)
this is a geometric sequence with
r = .96 and a1 = 93000 and n = 10 terms
sum of sequence = a1 (1-r^n) / ( 1-r) = 779264 kilotons
