Answer:
17*10^-3 miles
Step-by-step explanation:
Given data
Speed= 8.5×10^−6 miles per second
Time taken=2×10^3 seconds
We know that the expression for the speed is given as
speed= distance/time
distance= speed* time
substitute
distance= 8.5×10^−6* 2×10^3
distance= 8.5*2*(10^-6+3)
distance= 17*10^-3 miles

Can someone answer one of these rows. It’s volume of prisms.
Answer:
1.
Step-by-step explanation:
base formula
is length × height so that would be 11×4=44
base= 44
height=4
volume= 132
2.
base formula
since its a cube it would be length× hight = 36
base= 36
hight=6
volume =216
3.
base formula
pie×radius^2 so that would be 3.14×1.5^2= 14.80
base 14.80
hight 4
volume= 59.2

The solutions to the quadratic equation [tex]4(x+2)^2=36[/tex] are x = -5 and x = 1.
Given the following data:
[tex]4(x+2)^2=36[/tex]How to solve a quadratic equation.In this exercise, you're required to determine the value of x by solving for the factors (roots) of the given quadratic equation.
In Mathematics, the standard form of a quadratic equation is given by;
[tex]ax^2 + bx + c =0[/tex]
Where:
a = 4.b = 16.c = -20.Dividing both sides by 4, we have:
[tex]4(x+2)^2=36\\\\(x+2)^2=9[/tex]
Taking the square root of both sides, we have:
[tex]x+2=\pm3\\\\x=\pm 3-2[/tex]
x = -5 or 1.

A quality control inspector selects 12 bottles of apple juice at random from a single day’s production. The mean amount of apple juice in the bottles is 298.3 milliliters, and the 95% confidence interval for the true mean amount of juice dispensed per bottle is (296.4, 300.2). Does this interval give the quality control inspector reason to believe that the mean amount of juice in today’s bottles differs from 300 milliliters, as the juice label promises?
Answer:
The juice label (300ml) is in the confidence interval.
So, the 95% CI does not give the inspector the reason to believe the amount of juice differs from 300ml
Step-by-step explanation:
Given
[tex]95\%\ CI = (296.4, 300.2)[/tex]
[tex]Juice\ label = 300ml[/tex]
From the 95% confidence interval value, we have: 296.4 to 300.2
Within this interval, we can find the juice label 300
i.e. 296.4 < 300 < 300.2
In other words, the juice label (300ml) is in the confidence interval.
So, the 95% CI does not give the inspector any reason to believe the amount of juice differs from 300ml.

What is the area? Add the measurement of the shape. (ft, ft2, ft3,etc)
First to get it right gets brainliest
Answer:
24ft²
Step-by-step explanation:
Okay, so I don't understand what you're saying by the whole add the measurement thing, so if this is wrong, I'm very sorry.
Anyways, let's begin, the formula for the area of a triangle is base x height ÷ 2 so we just have to plug in our values:
12 x 4 = 48
48 ÷ 2 = 24
So the area of the triangle is 24ft²
hope this helps:)
For which equation is s = 6 not the solution?
4 s = 24
9 - s = 4
s + 6 = 12
s - 4 = 2
Answer:
9 - s = 4
Step-by-step explanation:
9 - 6 is 3, not 4, so thats the answer!
The equation is s = 6 not the solution is 9 - s = 4.
What is the equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
For which equation is s = 6 not the solution?
1. The solution of the equation 4 s = 24 is;
[tex]\rm4 s = 24\\\\s=\dfrac{24}{4}\\\\s=6[/tex]
2. The solution of the equation 9 - s = 4 is;
[tex]\rm 9 - s = 4\\\\s=9-4\\\\s=5[/tex]
3. The solution of the equation s + 6 = 12 is;
[tex]\rm s + 6 = 12\\\\s=12-6\\\\s=6[/tex]
4. The solution of the equation s - 4 = 2 is;
[tex]\rm s - 4 = 2\\\\s=2+4\\\\s=6[/tex]
Hence, the equation is s = 6 not the solution is 9 - s = 4.

Matt bought 7 shirts for a total of $38. Tee shirts cost $5 and long sleeve shirts cost $6. How many of each type of shirt did he buy? HELP PLZ 100 POINTS
Answer:
tee shirt:4
sleeve shirt:3
Step-by-step explanation:
we are given two conditions
Matt bought 7 shirts for a total of $38Tee shirts cost 5 dollars and long sleeve shirts cost 6 dollarswe want to figure out how many each type of shirt he bought
let tee and sleeve shirts be t and s respectively
according to the first condition
[tex] \displaystyle t + s = 7[/tex]
according to the second condition
[tex] \displaystyle5t + 6s = 38[/tex]
therefore
our system of linear equation is
[tex] \displaystyle\begin{cases}t + s = 7 \\ 5t + 6s = 38 \end{cases}[/tex]
so
now we need our algebra skills to figure out t and s
to do so we can use substitution method
cancel s from both sides of the first equation:
[tex] \displaystyle t = 7 - s \: \cdots \: i[/tex]
now substitute the value of i equation to the second equation:
[tex] \displaystyle 5(7 - s) + 6s = 38[/tex]
distribute:
[tex] \displaystyle 35 - 5s+ 6s = 38[/tex]
collect like terms:
[tex] \displaystyle s + 35 = 38[/tex]
cancel 35 to both sides:
[tex] \displaystyle \therefore s = 3[/tex]
now substitute the value of s to the i equation:
[tex] \displaystyle t = 7 - 3 \\ \therefore \: t = 4[/tex]
hence,
he bought tee shirt 4 and sleeve shirt 3

if you're looking for the radius then you'll have to divide the volume by pu and the height and do the squareroot over the whole equation
Which shows a correct comparison? A: 5 milliliters > 50 liters B: 2 liters < 200 milliliters C: 100 liters < 1,000 milliliteres D: 3,200 milliliters > 3 liters
Answer:
d
Step-by-step explanation:
Note that
> means greater than
< means less than
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
To determine which comparison is better we have to convert litre to millimetre
1 litre = 1000mm
A 5 mm > (50 x 1000)
5 mm > 50,000
5 is not greater than 50,000
B. (2 x 1000) < 200 mm
2000 < 200
2000 is not less than 200
C. (100 x 1000) < 1,000
100,000 < 1000
100,000 is not less than 1000
D. 3200 > (3 X 1000)
3200 > 3000
3200 is greater than 3000
You and your friend decide to conduct a survey at your school to see whether students are in favor of a new dress code policy. Your friend stands at the school entrance and asks the opinions of the first 100 students who came to campus on Monday. You obtain a list of all students at the school and randomly select 60 to survey
Your friend finds 34% of his sample in favor of the new dress code policy, but you find only 16%. Which do you believe us more likely to be representative of the school population? Explain your choice.
Answer:
34% in favor of the new dress code
Step-by-step explanation:
Because it has a higher percentage and when there is only 16% of students that doesn't really prove the claim or statement. But, when there is more participating or voting that claim or statement is supported.
