Hey there!☺
[tex]Answer:\boxed{1.6\times10^4}[/tex]
[tex]Explanation:[/tex]
To write an expression in standard form, you will have to rearrange the terms. 1.6 * 10^4 is already in its standard form.
So 1.6 * 10^4 in standard form would be written like this:
[tex]1.6\times10^4[/tex]
Hope this helps!☺

Name a pair of complementary angles in the diagram above.
A. 1 and 2
B. 2 and 3
C. 4 and 5
D. 7 and 9
Answer:
Step-by-step explanation:
(a) Use the Pythagorean theorem to determine the length of the unknown side of the triangle, (b)
determine the perimeter of the triangle, and (c) determine the area of the triangle. The figure is
not drawn to scale
Q
20 yd
15 yd
a. The length of the unknown side is
(Type a whole number)
b. The perimeter of the triangle is
(Type a whole number.)
c. The area of the triangle is
(Type a whole number)
Enter your answer in each of the answer boxes
Answer:
Step-by-step explanation:
Using the pythagorean theorem, we can solve to find C.
a^2 + b^2 = c^2
So it will be 15^2 + 20^2 = c^2
Simplify:
225 + 400 = c^2
625 = c^2
Square root both sides of the equation and you will get:
25 = c
c = 25
(a) The length of the unknown side is 25 yd
For perimeter, just add 20 + 15 + 25
(b) So the perimeter is 60 yd
The formula for area of a triangle is:
Area = (Base x Height) / 2
Now, we can plug in the numbers.
Base = 15
Height = 20
(15 x 20) / 2
300 / 2
= 150
(c) The area of the triangle is 150yd^2

when graphed on a coordinate plane, Bumby avenue can be represented by the equation y=-4x-7. Primrose Avenue can be represented by the equation 8x+2y=17
The complete question is;
when graphed on a coordinate plane, Bumby avenue can be represented by the equation y = -4x - 7. Primrose Avenue can be represented by the equation 8x + 2y = 17. Are these two parallel?
A) They are parallel because their slopes are the same
B) They are not parallel because their slopes are the same
C) They are parallel because their slopes are opposite reciprocals
D) They are not parallel because their slopes are opposite reciprocals
Answer:
Option D: They are not parallel because their slopes are opposite reciprocals
Step-by-step explanation:
Bumby avenue is represented by the equation y = -4x - 7 while Primrose Avenue can be represented by the equation 8x + 2y = 17.
Now, the general formula for slope intercept is;. y = mx + c.
Where m is the slope and c is the y - intercept.
This means the slope of bamby is - 4 while that of Primrose is 8.
The slopes are not the same and so options A and B are not correct.
Now, -4 is an opposite reciprocal of 8/-2.
But an opposite reciprocal means that both lines on the graph are perpendicular to each other.
Thus, option C is wrong because they are not parallel.
So correct option is D.
Jasmine wants to use her savings of $1,128 to buy video games and movies. The total price of the movies she bought was $72. The video games cost $43 each. Choose the inequality that would be used to solve for the maximum number of video games Jasmine can buy with her savings. 43 + 72x ≤ 1,128 43 + 72x ≥ 1,128 43x + 72 ≥ 1,128 43x + 72 ≤ 1,128
Answer:
The answer is 24. First 1128 - 72 equals 1056 then divide by 43 which equals 24.55 but u cant buy 24.55 VD so its just 24

A new car worth 24000 is depreciating in value by 3000 per year after how many years will the car be 12000
Answer:
4 years
Step-by-step explanation:
need to see how many times 3000 can go in 24000 and count how many years tell u get 12000
hopes I helped
Answer:
4 years
Step-by-step explanation:
subtract 3000 from 24000 then 3000 from the sum of each answer till you get to 12,000
after year 1: $21,000
24,000 - 3,000 = 21,000
after year 2: $18,000
21,000 - 3,000 = 18,000
after year 3: $15,000
18,000 - 3,000 = 15,000
after year 4: $12,000
15,000 - 3,000 = 12,000

How can you tell, without using the Law of Sines, that a triangle cannot be formed by using the measurements A= 89, B = 104, a= 28? Explain.
Answer:
Example 94. Solve the triangle shown with A=36º, B=88º and c=29 feet. Example 95 (no solution). Solve triangle ABC is A = ...
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
We are given two angles
A= 89, B = 104
Add the two angles 89+104 = 193
The sum of the angles of a triangle is 180
The two angles are greater than the sum of the three angles so it cannot be a triangle
What is the volume of a piece of copper that is 25 g., and the density is 8.9 g/cm3?
Answer:
The answer is 2.81 cm³Step-by-step explanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\[/tex]
From the question
mass = 25 g
density = 8.9 g/cm³
The volume is
[tex]volume = \frac{25}{8.9} \\ = 2.80898876...[/tex]

Answer:
1. c; 2. a; 3. b
Step-by-step explanation:
A(3,-1) translated to (3-4, -1+1)=(-1,0); then reflecting to x=1 (in this case, y doesn't change, and only x value change. x=-1 is 2 unit left side of x=1 line, so new reflected x value would be 2 unit right side of x=1 line, which is 3) gives (3,0).

However, you do not add it. Instead, the answer should be [tex]3y^2[/tex]
Use scalar multiplication to determine the coordinates of the vertices of the dilated figure.
Triangle with vertices A(1, 8), B(6, 1), and c(-9, 4) with scale factor 5/2
The coordinates of the vertices of the dilated figure are A'(1.25, 10), B'(7.5, 1.25), and C'(-11.25, 5).
Scalar MultiplicationThe multiplication of a vector with a positive real number without changing its direction is called scalar multiplication.
How to find the vertices of the dilated figure?The given triangle has the vertices A(1,8), B(6,1), and C(-9,4).
The matrix representation of the triangle ABC is,
[tex]\left[\begin{array}{ccc}1&6&-9\\8&1&4\end{array}\right][/tex]
And the scale factor is 5/2.
The matrix representation of the dilated figure can be obtained by multiplying the above matrix with 5/4.
[tex]=\dfrac{5}{4}\left[\begin{array}{ccc}1&6&-9\\8&1&4\end{array}\right]\\[/tex]
[tex]=\left[\begin{array}{ccc}\dfrac{5}{4}&\dfrac{15}{2}&\dfrac{-45}{4}\\10&\dfrac{5}{4}&5\end{array}\right]\\[/tex]
[tex]=\left[\begin{array}{ccc}1.25&7.5&-11.25\\10&1.25&5\end{array}\right][/tex]
Hence, the coordinates of the vertices of the dilated figure are A'(1.25, 10), B'(7.5, 1.25), and C'(-11.25, 5).

if the percentage tipped was 8% then you would multiply 75 by 0.08
One box of printer paper has 3 X 10^2 sheets of paper. Another box has 10^3 sheets of paper. What is the TOTAL number of sheets in BOTH boxes.
Answer:
1,300
Step-by-step explanation:
The Total number of sheets in both boxes are 1,300.
What is addition?Addition is a way of combining things and counting them together as one large group. Addition in math is a process of combining two or more numbers.
Now the given number of sheets in first box = 3 x 10^2 = 300
Given number of sheets in the second box = 10^3 = 1,000
Now to find the total number of sheets in both boxes,
Total number of sheets in both boxes
= sheets in first box + sheets in the second box
⇒Total number of sheets in both boxes = 300 + 1,100
⇒Total number of sheets in both boxes = 1,300
Hence,The Total number of sheets in both boxes are 1,300.
