Answer:
r= 7in
Step-by-step explanation. :)
x = r sin θ cos Ф
x² = r² sin² θ cos² Ф
y = r sin θ sin Ф
y² = r² sin² θ sin² Ф
z = r cos θ
z² = r² cos² θ
x² + y² + z²
= r² sin² θ cos² Ф + r² sin² θ sin² Ф + r² cos² θ
= r² sin² θ (cos² Ф + sin² Ф) + r² cos² θ
= r² sin² θ + r² cos² θ
= r² (sin² θ + cos² θ)
= r² √

URGENT PLEASE HELP
Answer:
Step-by-step explanation:
Person who wears a watch + ring
Lets say the fraction of people wearing the rings is 1/X
Lets say the fraction of people wearing a watch is 2/y
The formula is multiplication for both (Key words: and)
The formula is add for one or the either (key words: or)
The question says that person wears a watch given that they wear a ring
It mean that they wear a watch + a ring.
THat mean multiplication!
Lets use the example: 1/x · 2/y = 2/xy
This makes 2/xy your answer for the example.
Now lets do another example:
Lets say the fraction of people wearing the rings is 1/3
Lets say the fraction of people wearing a watch is 2/3
Multiplication!!!!
1/3 x 2/3 = 2/9
This makes 2/9 your answer to this example!!!!
Answer:
x=7
Step-by-step explanation:
x+4 + 2x1+3x-2 =45
6x+3 =45
6x=42
x=7
7+4 = 11
14+1=15
21-2=19
11+15+19 = 45
Answer: 9.8 percent
Step-by-step explanation:
It increased by 25 cents
25 out of 2.55 is .098 and turned to a percent is 9.8
Answer: 11
Step-by-step explanation:
2.30 ---- 100%
2.55 ----- x
x= 2.55* 100/2.30= 110.87
111-100 =11

4
of hers, and Britt ate 5 of her 8 slices. Order the girls, from greatest to least, according to how much of their pizzas they ate
A) Maria, Teloria, Britt
B) Britt ,Teloria, Maria
C) Teloria, Maria, Britt
D) Maria, Britt, Teloria
From greatest to least, the order of how much of their pizzas the girls ate is Maria, Britt, and Teloria.
So the answer is (D) Maria, Britt, and Teloria.
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To compare how much of their pizzas each girl ate, we need to convert the fractions to a common denominator.
Teloria ate 4/7 of her pizza, which is equal to 4/7 x 1 = 4/7.
Maria ate 3/4 of her pizza, which is equal to 3/4 x 1 = 3/4.
Britt ate 5 out of her 8 slices, which is equal to 5/8.
To convert the fractions to a common denominator, we can multiply 4/7 and 3/4 by 8/8, and multiply 5/8 by 7/7 as follows:
Teloria: 4/7 x 8/8 = 32/56
Maria: 3/4 x 8/8 = 24/32
Britt: 5/8 x 7/7 = 35/56
Now we can compare the fractions as follows:
Britt: 35/56
Teloria: 32/56
Maria: 24/32
We can simplify the fractions and write them as decimals as follows:
Britt: 35/56 = 0.625
Teloria: 32/56 = 0.5714
Maria: 24/32 = 0.75
Therefore, the answer is (D) Maria, Britt, and Teloria.
