Many weather conditions need to be met before a space shuttle can launch. The temperature must be greater than 35°F and less than 100°F, and the wind speed cannot exceed 30 knots. A system of inequalities can be used to show these three conditions. Write a system for the above constraints.
Answer:
Launch may not occur if the temperature is 35° F or colder.
would be your answer.
Step-by-step explanation:
The temperature cannot exceed 99° F for 30 consecutive minutes. Peak wind speed is 30 knots. When the wind direction is between 100 degrees and 260 degrees, the maximum wind speed may be as low as 24 knots.

Suppose for some value of x the solution to the equation 2.5(y−x)=0 is y = 6. What must be true about x?
HELPPPPPPPPPP
The value of the expression inside the parentheses must be equal to
Step-by-step explanation:
In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)
2.5(6-x) = 0
Open the bracket,
(2.5×6)-2.5x= 0
Collect like terms.
2.5x= 2.5×6
Divide both sides by the coefficient of x (2.5)
x = 6
So,
x= 6 is true.
.
Substituting 6 for x in the equation,
2.5(6-6)= 0
2.5•0 = 0
0= 0
Which is also true.
A piece of copper with a volume of 8.25 cubic centimeters has a mass of 73.92 grams. A piece of iron with a volume of 5 cubic centimeters has a mass of 39.35 grams. Which metal has the greater density?
PLEASE SHOW WORK, WILL MARK BRAINLIEST
A piece of copper with a volume of 8.25 cubic centimeters has a mass of 73.92 grams than has the greater density A piece of iron with a volume of 5 cubic centimeters has a mass of 39.35 grams.
How are density, volume and mass of a substance related?Suppose that a finite amount of substance is there having its properties as:
mass of substance = m kg
density of substance = d kg/m³
volume of that substance = v m³
Then, they are related as:
[tex]d = \dfrac{m}{v}[/tex]
A piece of copper with a volume of 8.25 cubic centimeters has a mass of 73.92 grams.
[tex]d = \dfrac{73.92}{8.25}\\d = 8.96[/tex]
A piece of iron with a volume of 5 cubic centimeters has a mass of 39.35 grams.
[tex]d = \dfrac{39.35}{5}\\\\d = 7.87[/tex]
Thus, A piece of copper with a volume of 8.25 cubic centimeters has a mass of 73.92 grams than has the greater density A piece of iron with a volume of 5 cubic centimeters has a mass of 39.35 grams.

What is the standard deviation of the data? 0.5 1.5 2.0 2.5
Answer:
0.74
Step-by-step explanation:
The standard deviation of a data set is the sqaure root of the variance, so first we must find the variance. The equation for variance is:
σ² = [tex]\frac{{(x_{1}-[x bar] )}^{2}+...+{(x_{n}-[x bar]) }^{2}}{n}[/tex]
x = number in the data set
xbar = median of the data set
n = number of terms
Plugging in the given values, the equation for the variance of this number set is:
σ² = [tex]\frac{(0.5 - 1.625)^{2} + (1.5 - 1.625)^{2}+ (2.0 - 1.625)^{2}+(2.5 - 1.625)^{2} }{4}[/tex]
Solving:
= [tex]\frac{1.265625+0.015625+0.140625+0.765625}{4}[/tex]
= [tex]\frac{2.1875}{4}[/tex]
σ² = 0.546875
Since the standard devianation is the sqaure root of the variance, we'll sqaure 0.546875:
[tex]\sqrt{0.546875}[/tex]
= 0.73950997288745
= 0.74 (rounded)

Answer:

At what price should Nepali bags be sold in order to make a profit of 140% by selling 2000 bags in the USA which was purchased in Nepal for Rs. 800 each and after paying 15% export tax ? [Given that $1 = Rs. 105.00.]
The price at which the Nepali bags should be sold in order to make a profit of 140% is $21.02.
What is the price the bags should be sold ?Profit is total revenue less total cost.
The first step to convert Rs. 800 to US dollars: 800 / 105 = $7.62
The second step is to determine the total cost including taxes: 1.15 x 7.62 = $8.76
Selling price = (1 + 1.40) x 8.76 = $21.02

Step-by-step explanation:
Answer:
T (1, 3), U (3, −17), V (−12, −8)
Step-by-step explanation:
To find the image as it is reflected from the preimage across the y-axis, apply the transformation rule, (x,y)→(−x,y), to each of the preimage points.
T(−1,3)→T'(1,3)
U(−3,−17)→U'(3,−17)
V(12,−8)→V'(−12,−8)
Draw lines between the found vertices to construct the reflected figure.
Therefore, the reflection of the figure with vertices T(−1,3), U(−3,−17), and V(12,−8) across the y-axis is the figure with vertices T'(1,3), U'(3,−17), and V'(−12,−8).

26) Anjali and Rob are selling cookie dough for a school fundraiser. Customers can buy packages of
sugar cookie dough and packages of oatmeal cookie dough. Anjali sold 6 packages of sugar cookie
dough and 2 packages of oatmeal cookie dough for a total of $116. Rob sold 9 packages of sugar
cookie dough and 12 packages of oatmeal cookie dough for a total of $318. Find the cost each of
one package of sugar cookie dough and one package of oatmeal cookie dough.
Answer:
Sugar cookie dough packages cost 14 dollars each, and oatmeal cookie dough packages cost 16 dollars each.
Step-by-step explanation:
Let s equal the cost of a sugar cookie dough package, and o equal the cost of oatmeal cookie dough packages.
6s + 2o = 116
9s+12o = 318
therefore,
18s+6o = 348
18s+24o = 636
Subtracting them, we get -18o = -288, or 18o = 288
Therefore, o = 16, and 6s+32=116, so 6s=84, so s = 14

1/2 x (a + b) x ha and b = length of parallel sidesh = heightSolving
Here : a = 5, b = 8, and h = 5Area = 1/2 x (5 + 8) x 5Area = 1/2 x 13 x 5Area = 65/2Area = 32.5 square feetAnswer:
32.5 square feet
Step-by-step explanation:
here we just find the area of both shapes within the trapezoid and add them, let's start with the triangle,
formula for the area of a triangle is 0.5 × base × height
therefore,
the area of the triangle is 7.5
the area of a square is equal to the length of the side squared.
5^2 = 25
the sum of 25 + 7.5 = 32.5
final answer is 32.5 square feet

The product of two numbers is 26 and one of the numbers is one larger than six times the other number. find the numbers.
Answer:
(-13/6, -12)
&
(2, 13)
Step-by-step explanation:
x · y = 26 -------> x = 26/y
y = 1 + 6x
SUB for y
x(1 + 6x) = 26
x + 6x² = 26
SOLVE for x
6x² + x - 26 = 0
6x² + 13x - 12x - 26 = 0
6x(x - 2) 13(x - 2) = 0
(6x + 13)(x - 2) = 0
x = -13/6 or 2
Test x = -13/6 for both equations
Equation 1
-13/6 · y = 26
y = -156/13
y = -12
Equation 2
y = 1 + 6(-13/6)
y = 1 - 13
y = -12
-12 = -12 ✅
Test x = 2 for both equations
Equation 1
2 · y = 26
y = 26/2
y = 13
Equation 2
y = 1 + 6(2)
y = 1 + 12
y = 13
13 = 13 ✅

A 10-speed bike changes gears by moving the chain to different size sprockets on the front and back. The speed at which the bike goes varies directly with the number of revolutions per minute (rpm) you turn the pedals, directly with the number of teeth on the front sprocket, and inversely with the number of teeth on the back sprocket. A standard bike with 70 cm diameter wheels will go about 7.4 kilometers per hour if you pedal 40 rpm in the lowest gear (39-tooth front sprocket, 28-tooth back one). Write an equation expressing km/h in terms of the three independent variables.
The variation is a joint variation, and the equation that relates the three independent variables is [tex]s = 0.18\frac{rf}{b}[/tex]
How to determine the equation in terms of the variables?The direct and the inverse variations from the question can be represented using:
[tex]s = k\frac{rf}{b}[/tex]
Where:
s represents the speed; s = 10k represents the constant of variationr represents the number of revolutions per minutef represents the number of front sprocket teethb represents the number of back sprocket teethFrom the question, we have:
r = 40; f = 39; b = 28
So, we have:
[tex]s = k\frac{rf}{b}[/tex]
[tex]10 = k\frac{40 * 39}{28}[/tex]
Make k the subject
[tex]k = \frac{10 * 28}{40 * 39}[/tex]
Evaluate
k = 0.18
Substitute k = 0.18 in [tex]s = k\frac{rf}{b}[/tex]
[tex]s = 0.18\frac{rf}{b}[/tex]
Hence, the equation that relates the three independent variables is [tex]s = 0.18\frac{rf}{b}[/tex]

What is the gcf of 36 and 90
I need help! This pattern repeats every 4 terms. The pattern is square, hexagon, trapezoid, triangle. What is the shape in the 7th term of this pattern?
==========================================================
Explanation:
There are two ways to do this problem.
Method 1 involves listing out the terms until we reach the seventh one.
squarehexagontrapezoidtrianglesquarehexagontrapezoidtriangleWe see that the trapezoid is term 7.
-------------
Method 2 is faster and the one I recommend.
Since the pattern repeats every 4 items, this means we divide by 4 and look at the remainder. Ignore the quotient entirely.
7/4 = 1 remainder 3
The remainder 3 means that the answer is found in term 3, which is the trapezoid.
