Answer:
A. 41
B. 1,590
C. .1
Step-by-step explanation:
A.
the equation is l*w=A
9.2*4.5=A
41.4=A
rounded it would be 41
B.
the equation is pi*r^2=A
3.14*22.5^2=A
3.14*506.25=A
1,589.6=A
^round this up to get 1,590
C.
what I did was use a*b/2 to find one side then add the other side (less complicated in my opinion)
.5*.2/2=A
.1/2=A
.05=A
.05+.05=0.1
Answer:
[tex]\text{a. }41.4\:\mathrm{m^2},\\\text{b. }1590.4\:\mathrm{cm^2},\\\text{c. }0.1\:\mathrm{m^2}[/tex]
Step-by-step explanation:
Part A:
The figure implies a rectangle. The area of a rectangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=bh[/tex].
What we're given:
[tex]b[/tex] of 9.2[tex]h[/tex] of 4.5Therefore, the area of the rectangle is [tex]9.2\cdot 4.5=\boxed{41.4\:\mathrm{m^2}}[/tex]
Part B:
The figure shows a circle. The area of a circle with radius [tex]r[/tex] is given by [tex]A=r^2\pi[/tex]. In the figure, the diameter is marked as 45 cm. To find the radius, we must divided this by 2, because by definition, the radius if half the diameter. Therefore, [tex]r=\frac{45}{2}=22.5\:\mathrm{cm}[/tex] and the area of this circle, rounded to the nearest tenth, is [tex]22.5^2\pi=1590.43128088\approx \boxed{1590.4\:\mathrm{cm^2}}[/tex]
Part C:
The figure shows a triangle (polygon with three sides). The area of a triangle with base [tex]b[/tex] and height [tex]h[/tex] is given by [tex]A=\frac{1}{2}bh[/tex].
What we're given:
[tex]b[/tex] of 0.4[tex]h[/tex] of 0.5Substituting given values, we get:
[tex]A=\frac{1}{2}\cdot 0.4\cdot 0.5=\boxed{0.1\:\mathrm{m^2}}[/tex]
Green River State Park had 312,684 visitors in one summer. Blue Sky State Park had 441,902 visitors.
1. How many fewer visitors did Green River State Park have than Blue Sky State Park? 2. Ashlee said that both state parks had a total of 753,586 visitors. Is Ashlee correct? Explain your reasoning.
Answer:
1. 129,218 fewer vistors than Blue Sku State Park
2. Ashley is not correct, since 441902 + 312684 is 754,586; not 753,586. She made a mistake on the thousands place, which she probably added one extra on accident.
Step-by-step explanation:
Oki, subtract for question one:
441902 - 312684 = 129218
Add for two:
441902 + 312684 = 754586
For problem, number two; I recommend writing it in your own words instead of copying off mines.

What is the slope of the line that passes through the points (26, 7) and (-39, 12)?
Answer:
-1/13
Step-by-step explanation:
The slope of a line is calculated as rise/run.
The rise is the difference in y-values, and the run is the difference in x values
slope= y₂ - y₁/x₂ - x₁
let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)
slope= (12 - 7)/ (-39 -26)
= 5/-65
reduce the fraction to get -1/13

Answer:

Step-by-step explanation:
( 2^-1 / 2^0) ^3
First simplify inside the parentheses
We know that a^b / a^c = a^(b-c)
2^(-1-0) = 2^-1
( 2^-1 ) ^3
Then we know that a power to a power is
a^b^c = a^(b*c)
2^(-1 *3)
2^ -3
Then a negative exponent makes it a fraction
a^ -b = 1/a^b

If <3 measures 123, what is the measure of <7?
Madison
River
A bridge crosses over the Madison River.
The opposite banks of the river are parallel
and the bridge is a transversal.
A. 90°
B. 123
C. 180°
D. 57
Answer: B
Step-by-step explanation: I just took the quiz
The measurement of angle 7 is 123°.
What are corresponding angles?The corresponding angles are angles that have the same relative position or measurement in two similar figures. They are formed when two lines, parallel or not, are intersected by a transversal. They are located on the same side of the transversal. Corresponding angles formed by parallel lines and a transversal are congruent.
Given is scene of two parallel line intersected by a transversal,
∠3 = 123°, We need to find the value of ∠7,
We see that, the angles, ∠3 and ∠7 are corresponding angles,
Therefore,
∠3 = ∠7 by the definition of corresponding angles between parallel lines,
Therefore, ∠7 = 123°.
Hence, the measurement of angle 7 is 123°.

d the volume of the entire figure by adding the volumes of the separate
Answer:
Total Volume = 190 m³
Step-by-step explanation:
Volume of the entire figure = L (Area 1 + Area 2)
where L = 10 m
Area 1 (blue prism) = 4 x 3 = 12 m²
Area 2 (brown prism = 1 x 7 = 7 m²

What is the measure of ∠4?
Answer:
80 degrees
Step-by-step explanation:
angle 1 is equal to 100 because of the law of exterior angles. And since andgle 1 and 2 make 180 degrees we can subtract 80 from 100 and we get the measure of angle 2. Angle 2 and 4 are the same becasue of the law of adjacent angles.

When the dragons have lost their most recent game, fans buy 200 tickets. For each consecutive win the dragons have, the number of tickets fans buy increases by a factor of 1.1 Which expression gives then number of tickets fans buy after 4 consecutive wins?
Answer:
Y(4) = 200(1.1)^4
Step-by-step explanation:
Given that :
Number of tickets purchased before consecutive wins = 200
For each consecutive win, ticket purchased increases by a factor of 1.1
Number of tickets after 4 wins
This scenario describes an exponential relation :
Where increase is factor based and not a certain number :
Hence,
Number of tickets, Y= Initial number of ticket * growth factor^number of wins
Hence, we have
Y(n) = 200(1.1)^n
Y(4) = 200(1.1)^4 = 292.82

Help me please!!! I really need it!
Answer: The value of x can be either 5 or 10.
Step-by-step explanation:
We are given:
Total profit, P = $5600
The given equation follows:
⇒ P = 600 + 1500x - 100x²
Putting value of P in above equation, we get:
⇒ -100x² + 1500x + 600 = 5600
⇒ -100x² + 1500x - 5000 = 0
⇒ 100x² - 1500x + 5000 = 0
Solving this equation by middle term split, we get:
⇒ 100(x² - 15x + 50) = 0
⇒ (x² - 10x - 5x + 50) = 0
⇒ x(x - 10) - 5(x -10) = 0
⇒ (x - 10)(x - 5) = 0
⇒ x = 10, 5
Hence, the value of x can be either 5 or 10.
A coin is tossed and a spinner with three equal-sized sections labeled 3, 6, and 9 is spun. What is the probability of getting heads and a number greater than 3? Express as a fraction in simplest form.
Answer:
The answer is 1/3.
Step-by-step explanation:
A coin has either heads or tails. The odds of a coin getting heads is 1/2.
There are three equal-sized sections with numbers 3, 6 and 9 on the spinner. There are two sections with numbers greater than 3, which are 6 and 9. The odds of getting a number greater than 3 is 2/3.
To find the overall probability of both incidents occurring, the two fractions are multiplied together, which is 1/2 * 2/3 = 1/3
Answer:
0.333/1/3
Step-by-step explanation:
Well, the probability of getting heads is 1/2 since there are 2 sides to a coin. There are 2 numbers on the spinner greater than three (6,9) which is 2/3.
1/2 times 2/3=0.33. The probability of getting heads and getting a number that is greater than is 0.333 or 1/3.

x1 = (-16 + 18)/2 = 2/2 = 1

x2 as negative value is no valid solution for a side length.
so, only x1 remand as solution.

A laptop has a listed price of $891.99 before tax. If the sales tax rate is 9.25%, find the total cost of the laptop with sales tax included.
Round your answer to the nearest cent, as necessary.
Please explain to me.
Answer:
$974.50
Step-by-step explanation:
The sales tax is 0.0925($891.99), or $82.51. We need only add this amount to the listed price ($891.99) to find the total cost with sales tax included:
$891.99
+ 82.51
--------------
$974.50
An alternative approach would be to multiply the listed price by 1.0925:
1.0925($891.99) = $974.50
Here the '1' refers to the listed price and the '0.0925' to the sales tax.
