Persevere with Problems William is 3 feet 1 inch tall and would like to ride a roller coaster. Riders must be at least 42 inches tall to ride the coaster. Write an addition inequality to determine how much taller William must be to ride the coaster. Let x be the variable representing how much taller William must be.
Answers
Step-by-step explanation:
1 ft = 12 in
he is 3 ft 1 in, that is then 3×12 + 1 = 37 in tall.
so,
37 + x >= 42
and then
x >= 42 - 37
x >= 5 in

[3 × √3 × √3 × √5] - [√5 × √5 × √5] + [√2 × √2 × √2 × √5 × √5] - [√2 × √5 × √5]
=[3 × 3 × √5] - [5 × √5] + [2 × 5 × √2] - [5 × √2]

Find the decay factor from the function y = 500(0.75)3.
Answers
The given function is:
[tex]y=500(0.75)^3[/tex]It is required to find the decay factor.
Recall that the standard form of an exponential decay function is given as:
[tex]y=a(b)^x[/tex]Where a>0, 0and b is the decay factor.
Compare the given equation to the standard form.
It can be observed that b=0.75. Hence, the decay factor is 0.75.
The answer is 0.75.Hank has picked 1.3 pounds of berries and picks about 0.75 pounds per min. Tom has picked 2.5 pounds of berries and picks about 0.5 pounds per minute. In how many minutes where are picked at least as many pounds of berries as Tom?
Answers
Hank: 1.3 pounds at a rate of 0.75 pounds per minute
Tom: 2.5 pounds at a rate of 0.5 pounds per minute
rate is given by
r = p / t
where p is the number of pounds picked during a fixed time
The number of berries picked by Hank during a certain time is given by the following equation
[tex]H=1.3+0.75t[/tex]For Tom, the equation is the following:
[tex]T=2.5+0.5\cdot t[/tex]Now, we need to find a time t when T and H are the same
[tex]\begin{gathered} H=T \\ 1.3+0.75t=2.5+0.5t \end{gathered}[/tex]We now just need to solve for t
Let's find t step by step
[tex]\begin{gathered} 1.3\cdot\: 100+0.75t\cdot\: 100=2.5\cdot\: 100+0.5t\cdot\: 100 \\ 130+75t=250+50t \\ 130+75t-130=250+50t-130 \\ 75t=50t+120 \\ 75t-50t=50t+120-50t \\ 25t=120 \\ \frac{25t}{25}=\frac{120}{25} \\ t=\frac{24}{5} \end{gathered}[/tex]Which is the same as t=4.8

Determine the inverse of the function f (x) = 2(x − 3)2 + 4.
Answers
The inverse of the function is [tex]f^-1 = \frac{1}{4}x + 2[/tex] .
What is inverse of the function ?
A function that "undoes" another function is known as an inverse in mathematics. To put it another way, if f(x) produces y, then y will produce x when y is fed into f's inverse function. A function f is said to be invertible if it has an inverse, and the inverse is represented by the symbol [tex]f^-1[/tex]
Here the given function is,
=> f(x) = 2(x-3)2+4
=> f(x) = 4(x-3)+4
=> f(x) = 4x-12+4
=> f(x) = 4x -8
Now take y= f(x) then,
=> y = f(x)=4x-8
=> y = 4x-8
Now interchange x and y then,
=> x = 4y-8
Now solve for y then,
=> x+8 = 4y
=> y= [tex]\frac{1}{4} x+ 2[/tex]
Then [tex]f^-1[/tex] = [tex]\frac{1}{4}x+ 2[/tex]
Therefore inverse of the function is [tex]f^-1 = \frac{1}{4}x + 2[/tex] .

Solve the system of equations :-6x - y = -16-6x -5y = -8
Answers
The given system of equation are :
-6x - y = -16
-6x -5y = -8
On subtracting both the equation we get :
-6x -y -(-6x -5y) = -16 -(-8)
-6x -y +6x +5y = -16 +8
-6x + 6x +5y -y = -8
4y = -8
4y = -8
Divide both side by 4:
4y/4 = -8/4
y = -2
Substitute the value of y =- 2 in the any one equation:
-6x - y = -16
-6x - (-2)= -16
-6x + 2 = -16
-6x = -16 -2
-6x = -18

C) 3/4
D)4/3
Answers
The value of sin Y is 4/5. The correct option is B) 4/5
Calculating the value of the sine of an angleFrom the question, we are to determine the value of sin Y.
From the given information, we have that
sin X = 3/5
and
cos X = 4/5
Also,
We have that angle X and angle Y are complementary angles.
That is,
X + Y = 90°
From the Trigonometric ratios of complementary angles, we have that
sin Y = cos (90° - Y)
From X + Y = 90°
X = 90° - Y
Therefore,
sin Y = cos X
From the given information,
cos X = 4/5
Hence, sin Y = 4/5

Answers
We have 20 coins in total, lets say that we have X amount od quarters(0.25 dollar) and Y amount of dimes(0.1 dollar), and in total we have $3.05, with this we can write the system:
[tex]X+Y=20[/tex]Wich means that we have 20 coins, and:
[tex]0.25X\text{ + 0.1Y=3.05}[/tex]Thats the amount of money we have.
So, from the first equation, we can isolate X, as follows:
[tex]X=20-Y[/tex]And with that we can substitute X in the second equation, as follows:
[tex]0.25X\text{ + 0.1Y=3.05 }\rightarrow\text{ }0.25(20-Y)\text{ + 0.1Y=3.05 }\rightarrow\text{ }5-0.25Y+0.1Y=3.05[/tex][tex]5-0.25Y+0.1Y=3.05\rightarrow-0.15Y=-1.95\rightarrow Y=13[/tex]So, if Y=13, we have that X=7. So 13 dimes and 7 quarters.

Answers
As given by the question
There are given that the total number of boys is 8 and total numbers of girls is 6.
Now,
Since there are two competitions, one for boys and one for girls and we want all the possible results we will calculate the possible combination for the boys and multiply them by the possible combination for the girls.
Then,
For the boys:
[tex]\begin{gathered} \text{Boys}=\frac{8!}{(8-3!)} \\ \text{Boys}=\frac{8!}{(8-3)!} \\ \text{Boys}=\frac{8!}{(5)!} \\ \text{Boys}=\frac{8\times7\times6\times5!}{(5)!} \end{gathered}[/tex]Then,
[tex]\begin{gathered} \text{Boys}=\frac{8\times7\times6\times5!}{(5)!} \\ \text{Boys}=8\times7\times6 \\ \text{Boys}=336 \end{gathered}[/tex]Now,
For the girl:
[tex]\begin{gathered} Girl\text{s}=\frac{6!}{(6-3)!} \\ Girls\text{s}=\frac{6!}{(3)!} \\ Girls\text{s}=\frac{6\times5\times4\times3!}{(3)!} \end{gathered}[/tex]Then,
[tex]\begin{gathered} Girls\text{s}=\frac{6\times5\times4\times3!}{(3)!} \\ Girls=6\times5\times4 \\ Girls=120 \end{gathered}[/tex]Now,
A total number of possible results:
