HOPE IT HELPEDThere are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Write the ratio of boys to girls in lowest terms.
Given that : There are a total of 76 teachers and students watching a school play. There are 4 teachers and 40 girls.
Need to find : the ratio of boys to girls in lowest terms.
Firstly we need to find out the number of boys . For that subtract the number of teachers and girls from total number of teachers and students. That will be ,
[tex]\implies \sf n( boys) = 76 - 4 - 40 =\red{ 32 }[/tex]
Therefore our required ratio will be:-
[tex]\implies \sf 32 : 40 = \boxed{\sf 4:5 }[/tex]
Hence the required answer is 4:5 .

Answer:
exact: V = 45pi in.^3
approximate: V = 141.4 in.^3
Step-by-step explanation:
V = (pi)r^2h
r = d/2 = 6 in./2 = 3 in.
V = (pi) * (3 in.)^2 * 5 in.
V = 45pi in.^3
V = 141.4 in.^3

Answer:
24
Step-by-step explanation:
Hanna: 20 1/4 cups per 9 servings.
We divide 20 1/4 by 9 to find the amount per serving.
20 1/4 / 9 = 81/4 / 9/1 = 81/4 * 1/9 = 9/4
Hanna's recipe uses 9/4 cup per serving.
Pocahontas: 3/4 cup more per serving than Hanna
9/4 + 3/4 = 12/4 = 3
Pocahontas uses 3 cups per serving
3 * 8 = 24
Pocahontas uses 24 cups of flour for 8 servings.

Answer:
54 degrees.
Step-by-step explanation:
So a fun fact is that the exterior angle is equal to the sum of the opposite two interior angles (at least within triangles).
Given this, set these values equal to each other to get the value of a.
d = a + b
2a = (a+10)+44
2a = a + 54
a = 54
The measure of the exterior angle is 54 degrees.

Write an inequality, in slope-intercept form, for the graph below. If necessary,
use '<="for < or ">" for >.
(-3,0)
X
5
(0, -3)
-5
Given:
The graph of an inequality.
To find:
The inequality in slope intercept form.
Solution:
The slope intercept form is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-0=\dfrac{-3-0}{0-(-3)}(x-(-3))[/tex]
[tex]y=\dfrac{-3}{3}(x+3)[/tex]
[tex]y=-1(x+3)[/tex]
[tex]y=-x-3[/tex]
From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".
[tex]y\geq -x-3[/tex]
Therefore, the required inequality is [tex]y\geq -x-3[/tex].

The expression 6k is an algebraic expression where 6 is the number of dollars Andrew earns per hour doing odd jobs and k is the number of hours he works. What expression describes the number of hours Andrew worked if he earned $30.00?
Answer: 30 = 6(5) thirty equals six times five.
Step-by-step explanation: Divide the total money earned by the pay Andrew gets for every hour to find how many hours Andrew worked to get that amount of money.
$30.00 = 6k

Given the conversion factor 12/1 in over 1ft, which cube has the larger surface area?
Answer:
Solid A
Step-by-step explanation:
3 feet is 3 x 12 = 36 inches, which is less than 48 inches, so solid A has a larger surface area than solid B.

Answer:
Option DStep-by-step explanation:
The graph of a function should pass the vertical line test in order to be a function.
Option A
Fails as repeat x-values of 14 with different y-valuesOption B
Fails as repeat x-values of 15 with different y-valuesOption C
Fails as repeat x-values of 16 with different y-valuesOption D
All x-values are different so this is a functionThe rule is .
Every domain of the function should have an unique range i.e f(x)=y
#1
f(14) has two values hence not a function
#2
f(15) has two values hence not a function
#3
f(16) has two values hence not a function
#4
Yes it's a function,every domain has an unique range
Which values represent the independent variable? (–2, 4), (3, –2), (1, 0), (5, 5) A. {–2, 3, 1, 5} B. {4, –2, 0, 5} C. {–2, 4, 3, –2} D. {–2, –1, 0, 5}
Answer:
Option A: {-2, 3, 1, 5}
Step-by-step explanation:
A function is a relationship that maps elements from one set (the domain, set of the inputs, the independent variables) into elements from another set (the range, set of the outputs, the dependent variables ).
Such that the standard notation is (x, y)
This says that the function/relation maps the element x into the element y.
So here the independent variable is x.
Now, in a relation:
{ (x₁, y₁), (x₂, y₂), ..., (xₙ, yₙ)}
The independent variable is represented with the set:
{x₁, x₂, ..., xₙ}
then, in the relation:
(–2, 4), (3, –2), (1, 0), (5, 5)
The set that represents the independent variable is a set with the first elements from each one of these four points:
{-2, 3, 1, 5}
The correct option is A.
When the sun is at a certain angle in the sky, a 50 foot building will cast a 20 foot shadow. What is the length of the shadow in feet cast by a 20 foot pole at the same time?
Answer:
Prepara a bar graph. (Mention the scale)
Potato= 25 per kg
Tomato= 40 per kg
Cauliflower= 10 per kg
Chilli= 15 per kg
Lemon= 30 per kg
Answer:
8 ft
Step-by-step explanation:
The height of the building/pole and shadow of each are in proportion.
let x be the length of shadow of the pole, then
[tex]\frac{50}{20}[/tex] = [tex]\frac{20}{x}[/tex] ( cross- multiply )
50x = 400 ( divide both sides by 50 )
x = 8
The shadow cast by the pole is 8 ft
