Answer:
15.5hr
Step-by-step explanation:
Speed = Distance/Time
Given
Distance = 1550ml
Speed = 100ml/hr
Required
Time
From the formula;
Time = Distance/Speed
Time = 1550/100
Time = 15.5hr
Hence it will take 15.5hr
If the standard deviation of shear strength measurements for spot welds is 9.5 pounds per square inch (psi), what is the minimum number of test welds that should be sampled if we want the sample mean to be within 1.4 psi of the true mean with probability approximately 0.99
Answer: 306
Step-by-step explanation:
Formula to find sample size:
[tex]n=(\dfrac{\sigma\times z^*}{E})^2[/tex] , where [tex]\sigma[/tex] = standard deviation, E = margin of error, z* = critrical z-value.
As per given,
[tex]\sigma=9.5 , E=1.4[/tex]
Critical z-value for 99% confidence = 2.576
Now , the minimum sampl size :[tex]n=(\dfrac{9.5\times2.576}{1.4})^2[/tex]
[tex]\Rightarrow\ n=305.5504\approx306[/tex]
Hence, the required sample size = 306

Buddy and his Step-brother Michael are in a snowball fight! They get hit by 85% of the snowballs.
If there were 200 snowballs thrown, how many were they hit by?
Answer: 170
Step-by-step explanation:
Since they get hit by 85% of the snowballs and there were 200 snowballs thrown, the number of snowballs that hit them will be gotten by multiplying 85% by 200. This will be:
= 85% × 200
= 0.85 × 200
= 170
Therefore, 170 snowballs hit them

A car traveled a total distance of 385 km. How long did it travel if its average speed was 55 kph?
Answer:
7 hours
Step-by-step explanation:
385/55 =7 ........
.
...
Answer:
6.5 hours
Step-by-step explanation:
to find time the equation is T=D/S
T= time D=distance S=speed
then you input what you know so
T=385/55
then I rounded to 6.5 hours
Find the solution of the equation in the interval 0° ≤ x < 360°
1. √3 csc x + 2 = 0
Step-by-step explanation:
√3cscx + 2 = 0
cscx = -2/√3
sinx = 1/cscx = -√3/2
We have the basic angle x = 60°.
(Because sin60° = √3/2)
Since sinx is negative, it must fall in Quadrants III or IV.
=> x = 180° + 60° or x = 360° - 60°
=> x = 240° or x = 300°.

A plane travels south for 120 km. The plane then travels north for 45 km.
If north is taken as the positive direction, what is the displacement of the plane?
a. 75 km
b. –75 km
c. 165 km
d. –165 km
Answer:
b. -75
Step-by-step explanation:
It is already stated in the problem that north direction is positive. Hence, south is negative.We take 120km south to be -120km.Then, travelling north by 45km.We then add the two: -120km + 45km = -75kmA polygon is transformed according to the rule: (x, y)-(x + 2, y). Every point of the polygon moves two units in which direction?
Answer:
Every point of the polygon moves horizontal translation right '2' units
Step-by-step explanation:
Explanation:-
Type of transformation Change of co-ordinate point
Vertical transformation
up 'd' units (x, y ) → ( x , y +d)
Vertical transformation
down 'd' units (x, y ) → ( x , y -d)
Horizontal transformation
left 'c' units (x, y ) → ( x-c , y )
Horizontal transformation
right 'c' units (x, y ) → ( x+C , y )
Given that a polygon is transformed according to the rule: (x, y)-(x + 2, y)
∴ Every point of the polygon moves horizontal translation right '2' units
Which table of values can be defined by the function y = 6x - 2?
Answer:
Simplifying
y = 6x + -2
Reorder the terms:
y = -2 + 6x
Solving
y = -2 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = -2 + 6x

11) In a triangle, the ratio of the measures of three angles is 2:5:8. Find the measures of
each angle in the triangle. Show proportions.
Answer:
Sum of interior angles of a triangle always = 180 degrees
add the individual ratios to get a sum composite ratio:
2+5+8 = 15
180 / 15 = 12
Multiply individual ratios:
{2:5:8} * 12 = 24:60:96
Check:
24 + 60 + 96 = 180
Step-by-step explanation:
I hope it's help
Triangle TUV is similar to triangle XYZ such that I and U correspond to X and Y , respectively. Each side of triangle TUV is the length of the corresponding side of triangle XYZ. The measure of angle V is 150°. What is the measure, in degrees, of angle Z? (Disregard the degree symbol when entering your answer.)
Answer:
its 150°
Step-by-step explanation:
if the two triangles are equal, it means they have the same angles
n^2 + 16n+63 (factor)
Step-by-step explanation: This trinomial is in a special form
that can be factored into the product of two binomials.
So setup 2 sets of parenthses.
The first term in each set is a factor of n²
and since n factors as n times n, we use an n.
For the second term, use factors of the last term that
add to the coefficient of the middle term.
The factors of 63 that add to 16 are 9 and 7.
So we have (n + 9)(n + 7) which is our answer.
At dinner last night, the total bill was $35.60. You left a 15% tip. What was the final price of your dinner?
Answer:
$40.94
Step-by-step explanation:
You first change 15% to .15
you then multiply that with 35.60
35.60
x .15
-----------
you then get the answer $5.30 which is how much your tip is.
now that you know how much your tip is your going to add it to the original price 35.60.
you then will get $40.94 as your total answer!
hopes this helped!! ;)
The solution to 4p+2<2(p+5) is
Answer:

Subtract 2p from both sides: 2p<8
Divide and we get: p<4
Answer:
p<4
Step-by-step explanation:
subtract 2 from both sides
subtract 2p from both

Given that DE is a midsegment for ABC and the length of DE is 8 units. What is the length of BC?
Answer:
BC = 16 units
Step-by-step explanation:
Since DE is the midsegment of the triangle, based on the midsegment theorem, thus:
DE = ½(BC)
DE = 8 units
Plug in the value
8 = ½(BC)
Multiply both sides by 2
2*8 = BC
BC = 16 units
