Answer: one-sixth
Step-by-step explanation:
Noah drew the circle which is divided into six equal parts
This shows that cherries must be divided into six persons
each sector of the circle is [tex]\frac{1}{6}^{th}[/tex] of the whole circle
From this, we can conclude that each person receives [tex]\frac{1}{6}[/tex] pound of cherries.
Justin took a quiz with five multiple choice (A-D) and five true/false questions. How many different ways can he answer the questions?
Answer:
32,768 ways
Step-by-step explanation:
True/ false questions = 5 ; number of options = 2 (True or false)
Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32
Number of Multiple choice questions = 5
Number of options (A - D) = 4 options
Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024
32 * 1024 = 32,768 ways

One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble. Each small bubble has a radius of 5 centimeters. What is the radius of the large bubble?
Answer:
R = 10 cm
Step-by-step explanation:
The area of a spherical shape is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the sphere
ATQ,
One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.
The radius of each small bubble is 5 cm
Using the given condition,
[tex]4\pi R^2=4\times (4\pi r^2)\\\\R^2=4r^2\\\\R=\sqrt{4r^2} \\\\R=2r\\\\R=2\times 5\\\\R=10\ cm[/tex]
So, the radius of the large bubble is equal to 10 cm.
Answer:
20cm
Step-by-step explanation:
5cm+5cm+5cm+5cm=20cm

Together Jason and Judy have read 24 mystery novels. Judy has read less than three times as many as Jason. How many mystery novels have each of them read.
Omitted / Incomplete Question : Judy has read 4 Less than three times as many as Jason
Answer:Jason has read 7 mystery novels and Judy has read 17 mystery novels
Step-by-step explanation:
Total number of mystery books read by Jason and Judy =24
Let Number of mystery books read by Jason=x
and Number of mystery books read by Judy= 3x-4
So that the total number of book read by both of them will be expressed as
x +(3x-4) =24
x +3x-4 =24
4x=24+4
4x=28
x=28/4=7
There fore Jason has read 7 mystery novels
and Judy = 3x-4 = 3 X 7- 4 =21-4=17mystery novels
cat face x+4/5=45 sa il aflu pe x
Given:
The equation is
[tex]x+\dfrac{4}{5}=45[/tex]
To find:
The value of x.
Solution:
We have,
[tex]x+\dfrac{4}{5}=45[/tex]
Isolating the variable, we get
[tex]x=45-\dfrac{4}{5}[/tex]
[tex]x=\dfrac{225-4}{5}[/tex]
[tex]x=\dfrac{221}{5}[/tex]
[tex]x=44.2[/tex]
Therefore, the value of x is 44.2.
Maria es una estudiante de la seccion 7-9 que le gusta leer mucho. Actualmente lee un libro que tiene 288 paginas, silee 12 paginas por dia, en cuanto tiempo leera maria todo el libro
Responder:
24 días
Explicación paso a paso:
Dado que:
Total de páginas = 288
Número de páginas leídas por día = 12
Número de días que se necesitarán para leer el libro completo:
Total de páginas / número de páginas leídas por día
288/12
= 24
Por lo tanto, a María le tomará 24 días leer el libro completo, si lee 12 páginas del libro por día.

PLEASE HELP I WILL MARK YOU BRAINLIEST determine the exact and approximat solutions for 4(x + 5)^2 = 21 show your steps
Answer:
x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21
Step-by-step explanation:
Let's solve your equation step-by-step.
4(x+5)^2=21
Step 1: Simplify both sides of the equation.
4x^2+40x+100=21
Step 2: Subtract 21 from both sides.
4x^2+40x+100−21 =21−21 4x^2+40x+79=0
For this equation: a=4, b=40, c=79
4x^2+40x+79=0
Step 3: Use quadratic formula with a=4, b=40, c=79.
x= −b±√ b^2−4ac/2ax
= −(40)+√ (40)^2−4(4)(79)/2(4)
x = 40^2±√ 336/8
x= −5+1/2 √ 21 or x = −5+ − 1/2√ 21
Answer: x = − 5 + 1/2 √ 21 or x = − 5 + − 1/2 √ 21

Answer:
Area = (8 + 2x)² mi²
Step-by-step explanation:
Length of the side of a park = 8 mi
Width of the road around the park = x mi
Length of one side of the park with the road = (8 + 2x) mi
Area of the park with road = (side)²
= (8 + 2x)²
Therefore, combined area of the park and road is (8 + 2x)² square miles.
