Katy organised a wedding. Guests had to choose their meal from pasta , chicken or beef . 1/3 of the guests chose pasta . 5/12 of the guests chose chicken . 24 of the guests chose beef. How many guests were at the wedding ?
please help i’ll give brainliest
Answer:
There were 96 guests at the wedding.
Step-by-step explanation:
Let,
x be the total number of guests at the wedding.
People who chose pasta = 1/3 of the guests = [tex]\frac{1}{3}x[/tex]
People who chose chicken = [tex]\frac{5}{12}x[/tex]
People who chose beef = 24
Now,
[tex]\frac{1}{3}x+\frac{5}{12}x+24=x\\\\\frac{4x+5x+288}{12}=x\\9x+288 = 12x\\288=12x-9x\\288=3x\\3x=288[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{288}{3}\\x=96[/tex]
Hence,
There were 96 guests at the wedding.

For which pair of functions is the exponential consistently growing at a faster rate than the quadratic over the interval 0 x 5?
Answer:
The correct answer is true because functions are exponential. (2,3)
The pair of functions that satisfies your question is y = 2x 2 and y = 2 x.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
Interval= 0 x 5
Now,
The exponential function is growing faster than the quadratic function over the interval 0 x 5, because it is above it for most of the interval.
Here is a table of values for these functions:
x y = 2x 2 y = 2 x
0 0 1
1 2 2
2 8 4
3 18 8
4 32 16
5 50 32
The y-values for the exponential function are larger than the y-values for the quadratic function for all x-values except x = 0.
Therefore, by the function the answer will be y = 2x 2 and y = 2 x.

Answer:
length = 7 in
width = 42 in
Step-by-step explanation:
length = x
width = 6x
perimeter = 98 in
[tex]2(x) + 2(6x) = 98 \\ 2x + 12x = 98 \\ 14x = 98 \\ x = \frac{98}{14} \\ x = 7[/tex]
length = x = 7 in
width = 6x = 6(7) = 42 in
Bob 's daily commute time is randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes, and the most common length is 30 minutes. What is the probability that his commute today took more than 35 minutes?
Answer:
0.6341 = 63.41% probability that his commute today took more than 35 minutes
Step-by-step explanation:
Randomly distributed = Uniform distribution.
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
Randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes.
This means that [tex]a = 20, b = 61[/tex].
What is the probability that his commute today took more than 35 minutes?
[tex]P(X > 35) = \frac{61 - 35}{61 - 20} = 0.6341[/tex]
0.6341 = 63.41% probability that his commute today took more than 35 minutes
Elke lives mile from 1/10school. Haresh lives 2/3 mile from school.
How much closer to school does Elke live than Haresh?
Simplify the answer if possible.
Answer: 17/30
Step-by-step explanation:
From the question, Elke lives 1/10 mile from school while Haresh lives 2/3 mile from school.
The closer to school Elke is than Haresh will be:
= 2/3 - 1/10
We can change the fractions to have thesame denominator which will be:
= 2/3 - 1/10
= 20/30 - 3/30
= 17/30
The distance between them is 17/30 miles

Alex asked her friend Beau to bring his robots to the fair. Guests can buy tickets to play with the robots. Beau needs to rope off an area to the fair grounds keep his robots in sight. Read his notes.
The area should be rectangular.
It needs to more then 100 feet long and less then 100 feet wide
The area needs to be between 7,500 and 10,000 square feet
Answer:
length = 100< l > 150
breadth = 50 < b> 100
Step-by-step explanation:
The area of the rectangle is given by the formula
Area= Length * Breadth
A= L*B
Suppose both the length and the breadth are 100 feet then the area would become
A= 100*100= 10,000 square feet.
The length and the breadth of the square are equal in size and we dont need a square we need a rectangle therefore these values cannot be inclusive for lenght and breadth.
It is given that the length is longer than 100 feet and breadth is shorter than 100 feet.Therefore
length can be 110 feet and breadth 90 feet
Again the area = A= l*b = 110 *90= 9,900 square feet.
Similarly putting different value from 50 to 150 feet for breadth and length we can obtain different results .
Area = l*b = 150*50 = 7500 square feet
for all values of the length between 100 to 150 feet and for breadth 50- 100 feet we can have the values of the area between 7500 to 10,000 square feet.
length = 100< l > 150
breadth = 50 < b> 100

Which of the following are solutions to the inequality below? Select all that apply.
35 ≤ 4 + 9d
A. D=11
B. D=8
C. D=10
D. D=9
Answer:
d ≤ 3.45
Step-by-step explanation:
The given inequality is :
35 ≤ 4 + 9d
We need to find the solution of the above inequality.
Subtract 4 from both sides of the inequality.
35-4 ≤ 4 + 9d -4
31 ≤ 9d
d ≤ 3.45
Out of all options, none is correct as the value of d is greater than equal to 3.45.
Find p(-1) and p(5) for the function p(x)= 9x to the 4th power+9x to the third power- 11x to the 2nd power+12x+5
Answer:
P(-1) = -18
P(5) = 6540
Step-by-step explanation:
Given the polynomial function
P(x) = 9x⁴+9x³-11x²+12x+5
We are to find p(-1) and p(5)
P(-1) = 9(-1)⁴+9(-1)³-11(-1)²+12(-1)+5
P(-1) = 9(1)+9(-1)-11(1)-12+5
P(-1) = 9-9-11-12+5
P(-1) = -23+5
P(-1) = -18
Get p(5)
P(5) = 9(5)⁴+9(5)³-11(5)²+12(5)+5
P(5) = 9(625)+9(125)-11(25)+65
P(5) = 5625+1125-275+65
P(5) = 6540

a linear equation is an equation in which the highest order of exponent is 1.
your equation is:
4x - y = 7
it's a linear equation.
none of the variables has an exponent larger than 1.
x = x^1
y = y^1
to find your ordered pairs, just take 3 values for x at random and plug them into the equation.
let x = 1,2,3
your equation is:
4x - y = 7
if you solve for y, it makes it easier to find the y value given the x value.
solve for y to get:
y = 4x - 7
when x = 1, y = -3
when x = 2, y = 1
when x = 3, y = 5
placing the equation into this form also allows you to graph it.
placing the equation into this form also gives you the slope-intercept form of the equation.
what you started with was the standard form of the equation for a straight line.
that standard form is ax + by = c
your equation is:
4x - y = 7
a = 4 and b = -1
the slope intercept form of the equation of a straight line is y = mx + b
m is the slope and b is the y intercept.
when you solved for y, you placed the equation into this form.
your slope is 4
your y intercept is -7
graph of your equation looks like this:

I placed horizontal lines at y = -3, 1, 5.
If you trace a vertical line down from the intersections of those lines with the line created by your equation, you will see that the value of x at those intersection points is 1,2,3
the points on the line formed by your equation are:
(x1,y1) = (1,-3)
(x2,y2) = (2,1)
(x3,y3) = (3,5)
you can take any other values of x and find the corresponding value of y by just replacing x in the equation with the value of x.
the equation is y = 4x - 7
when x = 5, y = 20-7 = 13, etc. brainlest pls

So far you have completed 816 miles
which is 43% of the trail.
Can you find about how many miles for the total trip?
Total Distance
Answer: 1898 miles
Step-by-step explanation:
Let the total distance of the trail be represented by x.
We are informed that 43% of the trail has been completed which is 816 miles, the total miles will then be:
43% × x = 816
43/100 × x = 816
0.43 × x = 816
0.43x = 816
x = 816/0.43
x = 1897.67
x = 1898 miles approximately
The total trip is 1898 miles
