Henry will spend at most $30 on gifts. So far, he has spent $21. What are the possible additional amounts he will spend? Use c for the additional amount in dollers henry will spend
Answer:
He will spend less than or equal to $9
Step-by-step explanation:
21 + c </= 30
c</= 9
Solve for xxx. -30=5(x+1)
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]
[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.

A random sample of size 16 is to be taken from a normal population having mean of 100 andvariance 4. What is the 90th percentile of the distribution of x?
The 90th percentile of the distribution of x is 100.64.
Given that,
A random sample of size 16 is to be taken from a normal population having mean of 100 and variance 4calculation:Here we have
[tex]n=16,\mu=100,\sigma^{2}=4[/tex]
Now we requried z-score that has 0.90 area to its left. z-score 1.28 has 0.90 area to its left.
So required 90th percentile is
[tex]z=\frac{\bar{x}-\mu}{\sigma/\sqrt{n}}\\\\1.28=\frac{\bar{x}-100}{2/\sqrt{16}}\\\\\bar{x}=100.64[/tex]

Given:
[tex]\to n=16\\\\\to \mu=100\\\\ \to \sigma^{2}=4[/tex]
To find:
distribution [tex]\bar{x}=?[/tex]
Solution:
We require a z-score with such a 0.90 area to its left in this case. The area to the left of the z-score 1.28 is 0.90. As a consequence, the required 90th percentile is
Using formula:
[tex]\to z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}\\\\[/tex]
[tex]\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{16}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{4^2}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{4}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{1}{2}}\\\\\to 1.28=\frac{\bar{x}-100}{0.5}\\\\\to 0.64 =\bar{x}-100\\\\\to \bar{x}=100+0.64\\\\\to \bar{x}=100.64\\\\[/tex]

Answer:

Step-by-step explanation:
The sum to n terms of a geometric series is
[tex]S_{n}[/tex] = [tex]\frac{a(1-r^{n}) }{1-r}[/tex]
where a is the first term and r the common ratio
Here a = 6144 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{3072}{6144}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]S_{10}[/tex] = [tex]\frac{6144(1-(\frac{1}{2}) ^{10}) }{1-\frac{1}{2} }[/tex]
= [tex]\frac{6144(1-\frac{1}{1024}) }{\frac{1}{2} }[/tex]

Find the original price given the total amount and the tip rate.
Total amount: $51.84
Tip: 20%
Answer:
62.208
Step-by-step explanation:
51.84 + 10.368
Answer:
I think if the total amount was $51.84 after tax, then 51.84 x 0.20 = 10.368. $51.84 - 10.368 = $41.472
I think original price was $41.47. I am not sure.
Step-by-step explanation:
A bear loves visiting his friend, the piglet. The distance between their houses is 300m, and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking 1/4 of the distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
10 min.
Step-by-step explanation:
Remember d = rt
The distance from bear's house to beehive = 75m and 225m = distance from beehive to piglet's house
Let r = normal rate of speed
The normal time is 300/r without stopping
75/r = time from bear's house to beehive
225/(r + 15) = time from beehive to piglet's house
So, time from beehive to piglet's house + time at beehive + time from bear's house to beehive = normal time without stopping
225/(r + 15) + 2.5 + 75/r = 300/r
225r + 2.5r(r + 15) + 75(r + 15) = 300(r + 15)
225r + 2.5r^2 + 37.5r + 75r + 1125 = 300r + 4500 Let's remove the deceimal by multiplying thru by 10
2250r + 25r^2 + 375r + 750r + 11250 = 3000r + 45000
25r^2 + 3375r + 11250 = 3000r + 45000
25r^2 + 375r - 33750 = 0
25(r^2 + 15r - 1350) = 0
25(r - 30 )(r + 45) = 0
r = 30 or -45 But, the rate cannot be negative, therefore r = 30
The journey takes 300/30 = 10 min.
By solving a system of equations, we will see that the journey takes 10 minutes.
How long does the journey take?
Let's define the variables:
S = usual speed of the bear.T = time in which the bear travels the total distance.We have that usually, the bear travels 300 meters in the time T, then we have:
S*T = 300m.
And in this situation, the bear also travels in the same time T, then we have:
First, the bear walks 1/4 of the distance, this is:
S*T/4
Then the bear stops for 2.5 minutes
Then the bear walks at 15m/min faster than usual for a time t..
S*T/4 + (S + 15 m/min)*t = 300m
Such that:
t + T/4 + 2.5 min = T.
Then we can write:
t = T - T/4 - 2.5 min = (3/4)*T - 2.5 min
Replacing that we get:
S*T/4 + (S + 15 m/min)*( (3/4)*T - 2.5 min) = 300m
Then we have a system of equations:
S*T = 300m.
S*T/4 + (S + 15 m/min)*( (3/4)*T - 2.5 min) = 300m
To solve this, we isolate one of the variables in one of the equations, I will isolate S in the first one:
S = 300m/T
Now we can replace this in the other equation:
(300m/T)*T/4 + (300m/T + 15 m/min)*( (3/4)*T - 2.5 min) = 300m
300m/4 + (300m/T + 15 m/min)*( (3/4)*T - 2.5 min) = 300m
Now we can solve this for T.
75m + 225m + (11.25 m/min)*T - (750m/min)/T - 37.5m = 300m
(11.25 m/min)*T - (750m/min)/T - 37.5m = 0m
If we multiply both sides by T, we get:
(11.25 m/min)*T^2 - (750m/min) - 37.5m*T = 0m
This is a quadratic equation, the solutions are given by:
[tex]T = \frac{37.5m \pm \sqrt{(-37.5m)^2 - 4*(11.25 m/min) (-750m/min)} }{2*(11.25 m/min)} \\\\T = (37.5m \pm 187.5m)/( 22.5 m/min)[/tex]
We only care for the positive solution, which is:
T = (37.5 m + 187.5m)/(22.5 m/min) = 10 min
So the journey takes 10 minutes.

is plane A or B faster
Answer:
The slope of the graph of plane A is 430, its speed is 430 miles per hour.
The slope of the graph of plane B is 460, its speed is 460 miles per hour.
Plane B is flying faster.
Step-by-step explanation:
The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:
Plane A
The slope of the graph of plane A is 430, its speed is 430 miles per hour.
Plane B
The slope of the graph of plane B is:
[tex]v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}[/tex]
[tex]v = 460\,\frac{mi}{h}[/tex]
The slope of the graph of plane B is 460, its speed is 460 miles per hour.
Therefore, plane B is flying faster.

One side of a rectangle is 3 yards longer than twice the length of another side. If the perimeter is 27 yards, what is the length of the longer side
Answer:
10 yards
Step-by-step explanation:
;)
The required length of the longer side is 10 yards.
What is the perimeter?Perimeter, is the measure of the figure on its circumference.
Here,
Let's assume that the length of one side of the rectangle is x yards. According to the problem, the other side of the rectangle is 3 yards longer than twice the length of this side. So, the length of the other side can be expressed as 2x + 3 yards.
The perimeter of a rectangle is the sum of the lengths of all its sides. So, we can write an equation to represent the problem:
Perimeter = 2 × length + 2 × width
Substituting the expressions for length and width, we get:
27 = 2(x) + 2(2x + 3)
27 = 2x + 4x + 6
27 = 6x + 6
21 = 6x
x = 3.5
So, the length of one side of the rectangle is 3.5 yards. The other side of the rectangle is 2(3.5) + 3 = 10 yards.
Therefore, the length of the longer side is 10 yards.
