A circle with area 64 cm2 has a
sector with a 45-degree
central angle.
The area of the sector is
cm2
9514 1404 393
Answer:
8 cm²
Step-by-step explanation:
A 45° sector is (45°)/(360°) = 1/8 of the circle, so its area is ...
(1/8)(64 cm²) = 8 cm² . . . . area of sector
A concert charges $5 for a children's ticket and $11 for an adult’s ticket. One Saturday, the theater sold 1200 tickets for $10,800. How many children’ tickets and adults’ tickets were sold?
Answer:
i think 15 kid and 18 aduits
Step-by-step explanation:
Answer:
800 children’s ticket were sold and 400 adult tickets were sold
Step-by-step explanation: using elimination
variables-
amount of children’s ticket sold: C
amount of adult tickets sold: A
equations-
A+C=1200
5A+11C=10,800
solving-
(A+C=1200) -5 —> -5A-5C=-6000
5A+11C= 10,800
use elimination on those two equation and you get C=800, A=400.
to check you plug in the numbers into one of the equations, doesn’t matter which one.

(3, 2)
(1).
f(x) = |x − 5| + 3
f(2) = |2 − 5| + 3 = |−3| + 3 = 3 + 3 = 6
(2).
f(x) = 8 − 3|x + 2|
f(−6) = 8 − 3|−6 + 2| = 8 − 3|−4| = 8 − 3·4 = 8 − 12 = − 4
(3).
For f(x) = |x − h| + k the turning point is (h, k), so:
f(x) = |x − 2| + 3 ⇒ the turning point is: (2, 3)
The value of f (2) will be;
⇒ f(2) = 6
The value of f (- 6) will be;
⇒ f(-6) = 4
The turning point of the graph will be;
⇒ (2, 3)
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
1) The function is,
⇒ f(x) = |x−5| + 3
2) The function is,
⇒ f(x) = 8 - 3 |x+ 2|
3) The function is,
⇒ f(x) = |x−2| + 3
Now,
1) The function is,
⇒ f(x) = |x−5| + 3
Put x = 2;
⇒ f (2) = |2 - 5| + 3
⇒ f (2) = 3 + 3
⇒ f(2) = 6
2) The function is,
⇒ f(x) = 8 - 3 |x+ 2|
Put x = - 6;
⇒ f (- 6) = 8 - 3 |- 6 + 2|
⇒ f (-6) = 8 - 3 × 4
⇒ f(-6) = 8 - 12
⇒ f (- 6) = - 4
3) The function is,
⇒ f(x) = |x−2| + 3
We know that;
Turning point of the function f (x) = |x - h| + k are (h, k)
So, By comparing we get;
The turning point of the graph of f(x) = |x−2| + 3 are (2, 3).
Thus, The value of f (2) will be;
⇒ f(2) = 6
The value of f (- 6) will be;
⇒ f(-6) = 4
The turning point of the graph will be;
⇒ (2, 3)

What is the solution set for this inequality -4x + 62 < -18
Answer:
x > 20
Step-by-step explanation:
-4x + 62 < -18
Add subtract 62 from both sides
-4x < -80
We can flip the sign and take away the negatives if both sides are negative.
4x > 80
Divide both sides by 4
x > 20

The Micro Devices Company earned 3,632,859,678 dollars this year. 2,459,632,852 dollars were earned last year. Which is the best estimate of how many more dollars were earned this year than last year?
Answer:
$1,173,226,826
Step-by-step explanation:
The estimate of the increase in dollars earnings is the difference between this year's earnings and last year's earnings. In other words, the increase in earnings is the excess of current year's earnings over last year's earnings as computed below:
increase in earnings=this year's earnings-last year's earnings
this year's earnings=$3,632,859,678
last year's earnings=$2,459,632,852
increase in earnings=$3,632,859,678-$2,459,632,852
increase in earnings=$ 1,173,226,826

Marco scored 20 points at the basketball game . If this is 40% of the total score, what was the total score for the basketball game ?
The total score for the basketball game was 50 points.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
Points scored by Marco in basketball game = 20
Also, points scored by Marco is 40% of the total score,
Implies that,
40% = 20
1 % = 20 / 40
To determine total score, find value of 100%,
100 % = (20 / 40) x 100
= 50
The total score for the basketball game was 50.

Tritan played in a football game he caught the ball at the goal line and ran forward 30 yards before he was tackled how could tristansrun be represented as a fraction and decimal of the whole football field
Answer:
As a fraction = [tex]\dfrac{30}{100}[/tex]
As a decimal = 0.3
Step-by-step explanation:
Recall that: The total yard of a football field = 100 yards
Tritan played in a football game he caught the ball at the goal line and ran forward 30 yards before he was tackled,
As a fraction;
Tristan run can be represented as = number of run from goal-line/ total length of the field
= [tex]\dfrac{30}{100}[/tex]

An adult can take 400 mg of ibuprofen. Each hour, the amount of ibuprofen decreases by 25%.
a. Write an equation of this exponential situation for the total amount of ibuprofen, y, in terms of the number of hours, x.
b. Does this situation represent exponential growth or decay? Explain how you know.
Answer:
a) y = 400(0.75) ^x
b) Exponential Decay
Step-by-step explanation:
An adult can take 400 mg of ibuprofen. Each hour, the amount of ibuprofen decreases by 25%.
a. Write an equation of this exponential situation for the total amount of ibuprofen, y, in terms of the number of hours, x.
This situation above is an exponential decay situation.
The forms is given as
y = a(1 - r) ^x
Where
y = the total amount of ibuprofen
a = initial amount of ibuprofen = 400mg
r = Decay rate = 25%
x = Time in hours
Hence, the Equation is written as
y = 400(1 - 0.25) ^x
y = 400(0.75)^x
b. Does this situation represent exponential growth or decay? Explain how you know
This situation represents an exponential decay because we are told in the question that each hour, the amount of ibuprofen DECREASES by 25%. Decrease in this context means Decay.
A ball is tied to a string and swung in a horizontal circle with a tangential speed of 2.5 m/s. The length of the string is 1.5m. Calculate the ball’s centripetal acceleration.
Answer:
[tex]a_c=4.17\ m/s^2[/tex]
Step-by-step explanation:
Centripetal Acceleration
It's the acceleration of an object moving in a uniform circular motion that pushed the object toward the center.
Its magnitude can be calculated as follows:
[tex]\displaystyle a_c=\frac{v^2}{r}[/tex]
Where:
v = tangential speed
r = radius of the circle
The ball is tied to a string describing a circular motion with a radius of r=1.5 m. The tangential speed is v=2.5 m/s, thus the acceleration is:
[tex]\displaystyle a_c=\frac{2.5^2}{1.5}[/tex]
[tex]\displaystyle a_c=\frac{6.25}{1.5}[/tex]
[tex]\mathbf{a_c=4.17\ m/s^2}[/tex]

The two containers are mathematically similar in shape.
The larger container has a volume of 3456 cm and a surface area of 1024 em'.
The smaller container has a volume of 1458 em.
Calculate the surface area of the smaller container,
[4]
Answer:
455.1 cm²
Step-by-step explanation:
The two containers have the following;
Large container
Volume : 3456 cm³
Surface area : 1024 cm²
Small container
Volume : 1458 cm³
Surface area : ?
If the two containers are mathematically similar then first find the volume scale factor
Volume of large/ volume of small
3456/1024 = 3.375
Length scale factor will be cube root of volume scale factor
∛3.375 = 1.5
Area scale factor is a square of the length scale factor
=1.5² = 2.25
=Surface area of the small container will be :
Larger area = 2.25 * small area
1024 = 2.25 * small area
1024/2.25 = small area
Surface area of the smaller container 455.1 cm².
