Answer:
380d + 530t > 21,000
Step-by-step explanation:
Each DVD costs $380, we can represent that as:
380d
Each TV costs $530, we can represent that as:
530t
We add these together to find the total profit:
380d + 530t
The manager predicts that whatever the total profit is, will be more than $21,000. So, we represent that as this:
380d + 530t > 21,000
And that is the final answer.
I hope this helps!!

If it takes you 40 seconds to travel from the first floor of a building to the third floor, how long will it take to travel from the first floor to the eighth floor (at the same pace, assuming all floors have equal height)? State your answer in seconds.
Answer: 104 seconds.
Step-by-step explanation: if it takes you 40 seconds to travel from the first to the third floor, then to pass one floor it will take 13 seconds. 40 divided by 3 which is 13. you then do 13x8 to figure out the time it would take you to travel through all the floors which is 104 seconds.
40/3 = 13
13 x 8 = 104
The answer is 104.

The length of the side, a, is approximately
The solution is
Answer:
b ≈ 13.7
Step-by-step explanation:
use the panthagrean thereom
a^2 + b^2 = c^2
10^2 + b^2 = 17^2
100 + b^2 = 289
-100 -100
b^2 = 189
√b^2 = √189
b = 13.74772708486752
b ≈ 13.7
The length of the side a in the given right-angled triangle is 8 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
The given right-angled triangle has a base of 15 units and a hypotenuse of 17 units.
Therefore,
17² = 15² + a².
a² = 17² - 15².
a = [tex]\sqrt{289 - 225}[/tex].
a = [tex]\sqrt{64}[/tex].
a = 8 units.

Travis's income is $3400 a month, and he plans to budge 3/8 of his income of savings and 1/3 of his income for groceries.
Step 2: What amount of money does he intend to spend each month of these items together? Round your answer to the nearest dollar.
Travis's will spend each month is $2,408
How to calculate the amount Travis will spend each month ?Travis income is $3400
He plans to budge 3/8 of his income on savings
He also plans to give 1/3 of the income on groceries
The amount spent on savings is
= 3/8 × 3400
= 3 × 425
= 1,275
The amount spent on groceries is
1/3 × 3400
= 3400/3
= 1,133.33
The amount spent altogether is
1,133.33 + 1,275
= 2,408.3

The coordinates of the point Q are (-7,-8) and the coordinates of point R are (-7,0). What is the distance, in units, between the point Q and point R?
The distance between the points Q and R is found to be 8 units.
What is defined as the distance formula?Algebraic expression that provides the distances between two points as a function of their coordinates (like coordinate system).
The distance equations for points in rectangular coordinates in two- and three-dimensional Euclidean space are based on the Pythagorean theorem.A line segment can be graphed both in two-dimensional & three-dimensional coordinate planes because it has a starting and stopping point. The two-dimensional coordinate plane allows the starting and stopping points to also be labeled as two-dimensional coordinates (x₁, y₁) and (x₂, y₂), respectively, resulting in the distance formula as: d = √(x₂ - x₁)² + (y₂ - y₁)².Now, as per the stated question;
The coordinates of the points Q and R are given as;
Q = (x₁, y₁) = (-7,-8)
And, R = (x₂, y₂) = (-7,0)
Now, substitute the values in the distance formula;
QR = √(-7 - (-7))² + (0 - (-8))²
QR = √(0)² + (8)²
QR = 8
Therefore, the distance between the points Q and R is calculated as 8 units.

4) The fishing fleet left Manilow Bay when the water level reached
32 feet. At 5:00am, the depth was 27 feet. The tide rose at the rate of 1
and ½ feet per hour for the next 6 hours. The depth of the water was
measured every hour on the hour. At what time may the fleet leave?
The time the fleet may leave the Manilow Bay given the rate at which the depth rises is 9am.
What time may the fleet leave?The fishing fleet would leave when the water level reaches 32. At 5 am, the water level is 27 feet. The water level needs to rise 6 more feet (32 - 27) before the fleet can leave.
In order to determine the time, divide 6 feet by the rate at which the tide rises. Division is the mathematical operation that is used to determine the quotient of two or more numbers.
Hours when the tide would rise 6 feet = 6 ÷ 1 1/2
6 x 2/3 = 4 hours
Add 4 hours to 5am : 5am + 4 = 9am

A tailor has a glass jars on a shelf.
Each jar holds 242 buttons. How many
buttons does the tailor have in all?
A 1,868
B) 1,800
C) 2,360
D) 2,178
Answer: D.
Step-by-step explanation: You can only have a whole number of jars. If you divide options A, B, and C, you will get a number with a wild decimal. Option D is correct because 2,178 divided by 242 is 9, which does not have a wild decimal.
John Beale of Stanford, California, recorded the speeds of cars driving past his house, where the speed limit read 20 mph. The mean of 100 readings was 23.84 mph, with a standard deviation of 3.56 mph. (He actually recorded every car for a two-month period. These are 100 representative readings.) a. How many standard deviations from the mean would a car going under the speed limit be? b. Which would be more unusual, a car traveling 34 mph or one going 10 mph?
How many standard deviations from the mean would a car going under the speed limit be -1.0787
Which would be more unusual: a car traveling 10 mph
Given data:
At speed limit of 20 mph mean of 100 readings was 23.84 mph
and a standard deviation of 3.56 mph
The speed limit read 20 mph
How to find the standard deviations from the mean that the car going under the speed limitAssuming the car going under the speed limit of 20 mph be y
such that
20 = 23.84 + y * 356
356y = 20 - 23.84
y = ( 20 - 23.84 ) / 356
y = -1.0787
How to find which is more unusualA car traveling 34 mph: using y same as number of deviations from the mean
34 = 23.84 + 3.56y
y = ( 34 - 23.84 ) / 3.56
y = 2.8539
Meaning the car travelling at 34 mph is 2.8539 standard deviations above the mean
A car traveling 10 mph: using y same as number of deviations from the mean
10 = 23.84 + 3.56y
y = ( 10 - 23.84 ) / 3.56
y = -3.8876
Meaning the car travelling at 10 mph is 3.8876 standard deviations below the mean
From the the rule that 99.7% of the observations lie with in ±3 standard. The speed of 10 mph is outside these limits but 34 mph is within the limits. Hence we say that the car travelling 10 mph is more unusual

Determine slope of any line perpindicular to GH. (-1,2) (-2,-1)
Answer:
Perpendicular slope = – 1/m = -1/3 = -1/3
Step-by-step explanation:
Given the points
(-1,2)(-2,-1)[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-1\right)[/tex]
[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]
[tex]m=\frac{-1-2}{-2-\left(-1\right)}[/tex]
[tex]m=3[/tex]
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 3
perpendicular slope = – 1/m = -1/3 = -1/3
Thus, the slope of any line perpendicular to GH = -1/3
