Answer:
320 girls
Step-by-step explanation:
We can make an algebric equation for this:
5x=900
x=180
We are asked to find the girls so we have to multiply the girls ratio by our x value we just found.
4x=4x180=320 girls
Which of the following choices are equivalent to the expression below? Check
all that apply. X^3/5
Answer:
[tex]\text{C. }(x^3)^{1/5},\\\text{F. }\sqrt[5]{x^3}[/tex]
Step-by-step explanation:
Exponent properties state [tex](a^b)^c=a^{(b\cdot c)[/tex]. Therefore, [tex]{x^{(\frac{3}{5})}=(x^3)^\frac{1}{5}[/tex].
Recall that [tex]a^{(\frac{b}{c})}=\sqrt[c]{a^b}[/tex]. Thus, [tex]x^{(\frac{3}{5})}=\sqrt[5]{a^3}[/tex].

The circus admits children for $2 each and adults for $5 each. How many of each ticket were sold if 160 total tickets were sold for $476? Please I need an answer ASAP
Answer:
adults = 52
children = 108
Step-by-step explanation:
two equations can be derived from the question
x + y = 160 equation 1
2x + 5y = 476 equation 2
x = number of children
y = number of adults
multiply equation 1 by 2
2x + 2y = 320 equation 3
subtract equation 1 from 2
3y = 156
y =52
substitute for y in equation 1
x + 52 = 108
x = 160 - 52 = 108

DWhat is 5/6 in simplest form
Answer:
5/6 in simpleest form is 5/6
It is already the lowest it can go
Answer:
Step-by-step explanation:
5/ 6 is already in the simplest form. It can be written as 0.833333 in decimal form (rounded to 6 decimal places).
Find the GCD (or HCF) of numerator and denominator
GCD of 5 and 6 is 1
Divide both the numerator and denominator by the GCD
5 ÷ 1
6 ÷ 1
Reduced fraction:
5/ 6
Therefore, 5/6 simplified to lowest terms is 5/6.
A number is divided into two parts, such that one part is 10 more than the other. If the two parts are in the ratio 5:3 find the number and the two parts.
Answer:
See below
Step-by-step explanation:
Given the above information, we can make the first part to be;
First part = y + 10
Then,
Second part = y
y + 10 : y = 5 : 3
(y + 10) / y = (5) / (3)
Cross multiply,
3y + 30 = 5y
Collect like terms
5y - 3y = 30
2y = 30
y = 15
Therefore, substituting the value of y,
First part = y + 10
First part = 15 + 10
First part = 25
Second part = y
Second part = 15
Number = First part + Second part
Number = 25 + 15
Number = 40

the answer is 33.4 because 33.4 x 2 is 66.8 and you add 1.2 + 1.2 that is 2.4. you add both and you get 69.2. Th answer is 33.4
Step-by-step explanation:
33.4 x 2 (1.2 x 2) + 69.2
brainliest pls.
Answer:
a = 33.4
Step-by-step explanation:
The short sides are both 1.2. You have to take them into account.
P = 2L + 2W
L is arbitrarily chosen to be the long side. The short side is W.
Givens
P = 69.2
L = a
W = 1.2
Solution
69.2 = 2 * 1.2 + 2a
69.2 = 2.4 + 2a
69.2 - 2.4 = 2a
66.8 = 2a
66.8/2 = a
a = 33.4

Step-by-step explanation:
The price of Stock A at 9 A.M. was $14.83. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $15.33. It begins to decrease at the rate of $0.15 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
0.5 hoursStep-by-step explanation:
Let the x be the number of hours after noon.
We have the following equation:
14.83 + 0.12(x + 3) = 15.33 - 0.15x 14.83 + 0.12x + 0.36 = 15.33 - 0.15x0.12x + 0.15x = 15.33 - 15.190.27x = 0.14x = 0.14/0.27x ≈ 0.5What is the sum of ( 3 . 4 × 10 8 ) + ( 7 . 5 × 10 8 ) ?

The difference of two numbers is 74. Twice the first and thrice the Second sum up to 138. Find the two possible numbers . anyone??
Answer:
72 and -2
Step-by-step explanation:
x - y = 74
2x + 3y = 138
x - y = 74
y = x - 74
2x + 3(x - 74) = 138
2x + 3x - 222 = 138
5x = 360
x = 72
x - y = 74
72 - y = 74
-y = 2
y = -2
A rectangle has a perimeter of 6 feet.
Choose all the possible dimensions of the rectangle.
A. 1 foot by 2 feet
B. 1 foot by 5 feet
C. 2 feet by 1 foot
D. 2 feet by 4 foot
E. 3 feet by 3 feet
F. 4 feet by 2 feet
G. 5 feet by 1 foot
Option (A) 1 foot by 2 feet and option (C) 2 feet by 1 foot satisfy the perimeter given. Thus options A and C are correct.
What is a rectangle?"A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles".
For the above situation,
The length of the rectangle be 'l'
The breadth of the rectangle be 'b'
Perimeter of the rectangle, P = 2(l+b)
Option A : 1 foot by 2 feet
Here, l = 1 feet and b = 2 feet
⇒ [tex]P=2(l+b)[/tex]
⇒ [tex]P=2(1+2)\\[/tex]
⇒ [tex]P=6[/tex]
This perimeter is equal to the perimeter of the rectangle. Thus option A is correct.
Option B : 1 foot by 5 feet
Here, l = 1 and b = 5 feet
⇒ [tex]P=2(1+5)[/tex]
⇒ [tex]P=12[/tex]
This perimeter is not equal to the perimeter of the rectangle. Thus option B is not correct.
Option C : 2 feet by 1 foot
Here, l = 2 and b = 1 feet
⇒ [tex]P=2(2+1)[/tex]
⇒ [tex]P=6[/tex]
This perimeter is equal to the perimeter of the rectangle. Thus option C is correct.
Option D : 2 feet by 4 foot
Here, l = 2 and b = 4 feet
⇒ [tex]P=2(2+4)[/tex]
⇒ [tex]P=12[/tex]
This perimeter is not equal to the perimeter of the rectangle. Thus option D is not correct.
Option E : 3 feet by 3 feet
Here, l = 3 and b = 3 feet
⇒ [tex]P=2(3+3)[/tex]
⇒ [tex]P=12[/tex]
This perimeter is not equal to the perimeter of the rectangle. Thus option E is not correct.
Option F : 4 feet by 2 feet
Here, l = 4 and b = 2 feet
⇒ [tex]P=2(4+2)[/tex]
⇒ [tex]P=12[/tex]
This perimeter is not equal to the perimeter of the rectangle. Thus option F is not correct.
Option G : 5 feet by 1 foot
Here, l = 5 and b = 1 feet
⇒ [tex]P=2(5+1)[/tex]
⇒ [tex]P=12[/tex]
This perimeter is not equal to the perimeter of the rectangle. Thus option G is not correct.
Hence we can conclude that option (A) 1 foot by 2 feet and option (C) 2 feet by 1 foot satisfies the perimeter given. Thus options A and C are correct.

What is the volume of this triangular prism?
Answer:
Given:
perpendicular [p]=9cm
base[b]=15cm
length[l]=4cm
we have
the volume of this triangular prism=area of traingle. ×length=1/2 p×b×l
=½×9×15×4=270cm³
270cm³ is a required volume.
Answer:
[tex]\displaystyle V _{ \text{prism}} = 270 {cm}^{3} [/tex]
Step-by-step explanation:
we are given a triangular prism
we want to figure out the Volume of the given Prism
remember that,
[tex] \rm\displaystyle V _{ \text{prism}} = [\text{base area}] \times l[/tex]
since the base is triangle the formula of base area should be the formula of the area of a triangle
thus,
[tex] \rm\displaystyle V _{ \text{prism}} = [\frac{1}{2}\times b\times h] \times l[/tex]
substitute
[tex] \rm\displaystyle V _{ \text{prism}} = [\frac{1}{2}\times 9 \times 15]\times 4[/tex]
remove parentheses:
[tex] \displaystyle V _{ \text{prism}} = \frac{1}{2}\times 9\times 15\times 4[/tex]
reduce fraction:
[tex]\displaystyle V _{ \text{prism}} = 9\times 15\times 2[/tex]
simplify multiplication:
[tex]\displaystyle V _{ \text{prism}} = 270[/tex]
hence, the Volume of the given prism is 270cm³

"The sum of negative two and nine times a number is less than ninety four."
Answer:
I believe you would write the answer is 7 * x is less than 94 (use actual less than symbol for answer).
Step-by-step explanation:
"The sum of negative two and nine" is saying -2 + 9.
"times a number" is saying the answer of -2 + 9 is multiplied by a number, or x.
"is less than ninety four." is saying that -2 + 9 * x is less than (use symbol) 94.
So the equation looks like this:
-2 + 9 * x is less than 94.
Now you can simplify the equation:
-2 + 9 = 7
7 * x is less than(use actual less than symbol) 94.
