A pizza parlor sells pizza in two sizes, a 16 inch pizza or a 10inch pizza. Which is more pizza, half of the 16-inch pizza or the entire inch pizza?
Topic: arc length and sector area
Answer:
Therefore the second pizza of 10inch is More
Y>X
Step-by-step explanation:
From the question we are told that:
Diameter of pizzas
Pizza one [tex]D_1=16[/tex]
Pizza two [tex]D_2=10[/tex]
Generally the equation for amount of half of pizza one X is mathematically given by
[tex]X=\frac{1}{2}\pi r^2[/tex]
[tex]X=\frac{1}{2}\pi 8^2[/tex]
[tex]X=100.53inch^2[/tex]
Generally the equation for amount of pizza two Y is mathematically given by
[tex]Y=\pi r^2[/tex]
[tex]Y=\pi 10^2[/tex]
[tex]Y=314.16inch^2[/tex]
Therefore the second pizza of 10inch is More
Y>X

On a certain hot summer's day, 335 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $619.2. How many children and how many adults swam at the public pool that day?
Answer:
57
Step-by-step explanation:
Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = -
$70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57
A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probability that the point is inside the circle?
Given :
A circle is inscribed in a square with a side length of 144.
So, radius of circle, r = 144/2 = 72 units.
To Find :
The probability that the point is inside the circle.
Solution :
Area of circle,
[tex]A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2[/tex]
Area of square,
[tex]A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2[/tex]
Now, probability is given by :
[tex]P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785[/tex]
Therefore, the probability that the point is inside the circle is 0.785 .

Two coins are flipped. What is
the probability that one will
land on tails and the other coin will land on heads?
Answer:
the probability is 0.25
Step-by-step explanation:
first flip if head:0.5
second flip after head:0.5 each
first flip if tails:0.5
second flip after tails:0.5 each
0.5 x 0.5 = 0.25
Find the measure of the indicated arc
Answer:
m(arc WXY) = 224°
Step-by-step explanation:
By inscribed angle theorem,,
"Measure of intercepted arc is double of the inscribed angle"
m(arc WXY) = 2[m(∠YCW)]
Here, arc WXY is the intercepted arc and ∠YCW is the inscribed angle.
By substituting the value of inscribed angle,
m(arc WXY) = 2(112°)
= 224°
Therefore, measure of arc WXY is 224°.
Is anyone able to help me out with this???
Answer:
x = 24
Step-by-step explanation:
To simplify the work we can use the Pytaghoran theorem in this way:
x^2 + x^2 = (24√2)^2
2x^2 = 24^2 *(√2)^2
2x^2 = 576 * 2
x^2 = 576
x = +/- √576
x = +/- 24
we choose only the positive value because a length can’t be negative
x = 24

9. The gradient of the curve y=kx⁴ at the point x = 2 is 128. Find the value of k.
Answer:
k = 4
Step-by-step explanation:
Here, we want to find the value of k
Mathematically, the gradient of a curve is same as the first derivative
so the first derivative here is;
dy/dx = 4kx^3
Now, the value of x here is 2 while the value of y is 128
Substituting these values;
128 = 4k(2)^3
128 = 32k
k = 128/32
k = 4

Subtracting fractions with unlike denominators
Answer:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Step-by-step explanation:
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
LCD(9/4, 5/10) = 20
[tex](\frac{9}{4} * \frac{5}{5} ) - (\frac{5}{10} * \frac{2}{2} ) = ?[/tex]
Complete the multiplication and the equation becomes
[tex]\frac{45}{20} - \frac{10}{20}[/tex]
The two fractions now have like denominators so you can subtract the numerators.
Then:
[tex]\frac{45 - 10}{20} = \frac{35}{20}[/tex]
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 35 and 20 using
GCF(35,20) = 5
[tex]\frac{35 / 5 }{20 / 5} = \frac{7}{4}[/tex]
The fraction
[tex]\frac{7}{4}[/tex]
is the same as
7 ÷ 4
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]
Apply the fractions formula for subtraction, to
[tex]\frac{9}{4} - \frac{5}{10}[/tex]
and solve
[tex]\frac{(9 * 10)- (5* 4) }{4 * 10}[/tex]
[tex]= \frac{90-20}{40}[/tex]
[tex]= \frac{70}{40}[/tex]
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(70,40) = 10
[tex]\frac{70/ 10 }{40 / 10} = \frac{7}{4}[/tex]
Convert to a mixed number using
long division for 7 ÷ 4 = 1R3, so
[tex]\frac{7}{4} = 1\frac{3}{4}[/tex]
Therefore:
[tex]\frac{9}{4} - \frac{5}{10} = 1\frac{3}{4}[/tex]

Can someone please help me with math.
Hello, can you help me please
Step-by-step explanation:
1. C(x) is in vertex form so let write the function out.
[tex]a(x - 1) {}^{2} + b[/tex]
B is our maximum value so b=9.
[tex]a(x - 1) { }^{2} + 9[/tex]
To find a, we know that when x=5 is a root so plug 5 in for x to find a.
[tex]a(5 - 1) {}^{2} + 9 = 0[/tex]
[tex]a(4) {}^{2} + 9 = 0[/tex]
[tex]16a = - 9[/tex]
[tex]a = - \frac{9}{16} [/tex]
2.. Let convert Chelesa function into. standard form.
[tex] \frac{ -9 }{16} (x - 1) {}^{2} + 9[/tex]
[tex] - \frac{9}{16} (x {}^{2} - 2x + 1) + 9[/tex]
[tex] - \frac{9}{16} {x}^{2} + \frac{9}{8} x + \frac{135}{16} [/tex]
Let see which value has the higher constant.
135/16 is more than 8 so Chelsea jumper higher.
3. Set Herritea equation equal to zero.
[tex] - \frac{2}{9} {x }^{2} + 8 = 0[/tex]
[tex] - \frac{2}{9} x {}^{2} = - 8[/tex]
Multiply both sides by the reciprocal of negative 2/9.
[tex] {x}^{2} = - 8 \times - \frac{9}{2} [/tex]
[tex] {x}^{2} = 36[/tex]
[tex]x = 6[/tex]
