Answer:
9[tex]\pi[/tex]
Step-by-step explanation:
The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.
EQUATION FOR AREA OF A CIRCLE: [tex]\pi r^{2}[/tex]
When you put it all together you get: [tex]\pi * 3^{2}[/tex] which equals [tex]9\pi[/tex]
DO NOT MULTIPLY 9 AND PI. IT'S JUST 9[tex]\pi[/tex]

Answer:
58%
Step-by-step explanation:
Lo siento. No soy bueno con el español, así que estoy usando translate. Espero que esté bien.
Entonces, para esta ecuación, usaremos un porcentaje igual o superior a 100 como se indica aquí. ([tex]\frac{es}{de}[/tex] = [tex]\frac{porciento} {100}[/tex]) Entonces tu ecuación es [tex]\frac{28}{49}[/tex] = [tex]\frac{x}{100}[/tex]
Multiplicará 28 por 100, lo que le dará 2800. Luego, dividiría 2800 entre 48, lo que le daría 58. Entonces, su respuesta sería x = 58%.
Lo siento si no entiende algo de esto porque los traductores no siempre son correctos. Pero espero que esto haya ayudado :)

Answer:
6.825
Step-by-step explanation:

Multiply by the percentage.
65 * 0.105 = 6.825
Matt and Ash are selling fruit for a school fundraiser. Customers can buy small boxes of fruit or
large boxes of fruit. Matt sold 3 small boxes and 5 large boxes for a total of $47. Ash sold 11 small
boxes and 10 large boxes for a total of $114. What is the cost of a small box of fruit?
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7

Can someone please help me this problem? Thanks :)
Answer: B) 2/3
====================================================
Work Shown:
Method 1
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (3-1)/(-1 - (-4)) ..... using the first two rows as points
m = (3-1)/(-1 + 4)
m = 2/3 is the slope
-----------------------------------
Method 2
Each time y goes up by 2, x goes up by 3.
For instance, the jump from y = 1 to y = 3 is "plus 2". At the same time, the jump from x = -4 to x = -1 is "plus 3".
We can then say
slope = (rise)/(run)
slope = (change in y)/(change in x)
slope = (y increase by 2)/(x increase by 3)
slope = 2/3
An object is moving at a speed of 7 meters every 9 days. Express this speed in centimeters per year. Round your answer to the nearest whole number.
Answer:
28400cm
Step-by-step explanation:
if 9 days=7m
:.365 days=?
365×7/9
283.88888
rounded off to nearest whole number =284m
change to cm=28400cm
The speed of the object expressed in centimeters per year and rounded to the nearest whole number is 28390 cm/yr
Speed per day = Distance / Number of days
Speed per day = 7 meters ÷ 9 days = 0.7778 m/day
Converting to centimeters per year :
1 meter = 100 cm1 day = 1/365 yearsHence,
0.7778 m/day = (0.7778 × 100cm) ÷ (1/365 years)
(0.7778 × 100cm) ÷ (1/365 years) = (77.78 cm ÷ 0.0027397 year)
0.7778 m/day = 28389.7 cm / year
Therefore, the speed of the object is 28390 cm/yr

Which graph represents the equation below?
Answer:
c
Step-by-step explanation:
we can see that the "a" value is -1, written as just "-" meaning the parabola is going to face down, this eliminates A and D, then if we solve for the x intercepts, ( set the values in the parenthesis equal to 0) we see that the intercepts are negative one and positive 3
The graph which represents the equation f(x) = -(x + 1)(x - 3) is graph C.
Given a function that has the equation form:
f(x) = -(x + 1)(x - 3)
It is required to find the graph of this function.
The equation is clearly in the form of a factorized quadratic equation.
So the graph will be clearly parabola.
Now, when the equation is expanded, the equation will be of the form:
f(x) = -(x² -2x -3)
= -x² + 2x + 3
The leading coefficient is negative. So the parabola opens downward.
This eliminates options A and D.
The remaining options are B and C.
From the factored form, the zeroes of the function are:
-(x + 1)(x - 3) = 0
(x + 1)(x - 3) = 0
x = -1 and x = 3
That is, the graph touches the X-axis at x = -1 and x = 3.
The vertex coordinates are:
x = -b/2a = -2/-1 = 1
y = f(-b/2a) = -(1+1)(1-3) = 4
Hence the correct option is C.

The bases of a trapezoid are 16.8 yards and 6.9 yards. If the height is 2 yards, what is the area of the
trapezoid?
47.4 yd 2
9.9 yd 2
23.7 yd 2
19.8 yd 2
Given:
Bases of a trapezoid are 16.8 yards and 6.9 yards.
The height is 2 yards.
To find:
The area of the trapezoid.
Solution:
We know that, area of a trapezoid is
[tex]Area=\dfrac{\text{Sum of bases}\times \text{Height}}{2}[/tex]
Using this formula, we get
[tex]Area=\dfrac{(16.8+6.9)\times 2}{2}[/tex]
[tex]Area=\dfrac{(23.7)\times 2}{2}[/tex]
[tex]Area=23.7\text{ yards}^2[/tex]

Charles wants to compare the solutions to the equations x^2=64 and x^3=64.
Compare the signs of the solutions. Explain your reasoning.
Answer:
x = ±4
x = 4
Step-by-step explanation:
x² = 64.
Square root both sides
√x² =√64
x= ±8
When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.
x³ = 63.
Cube root both sides
3√x³ = 3√65
x =4
This only gives a positive number not negative since the product of three negative number gives a negative number
