which step comes first -b-2<8
Answer:
Step-by-step explanation:
Alright so the step that comes first is adding two to both sides.
Let me show you,
Step 1
-b-2<8 Add 2 to both sides
-b<10
Then you divide the sides by -1
-b<10
b>-10
14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.

Find zeros and y intercept of each function algebraically f(x)=x^3-10x^2+24x
Answer:
The zeros are 0, 4, 6.
The y-intercept is 0.
Step-by-step explanation:
f(x) = x^3 - 10x^2 + 24x
x^3 - 10x^2 + 24x = 0
x(x^2 - 10x + 24) = 0
x(x - 4)(x - 6) = 0
x = 0 or x - 4 = 0 or x - 6 = 0
x = 0 or x = 4 or x = 6
y-intercept:
Since x = 0 is a root, that means that the point (0, 0) is part of the function. That makes the y-intercept 0.
You can also solve for the y-intercept by letting x = 0 in the function and solving for f(0).
Let x = 0.
f(0) = 0^3 - 10(0^2) + 24(0)
f(0) = 0
y-intercept: 0

work out the size angle DEF
Answer:
Step-by-step explanation:
Here, we want to get the value of angle DEF
we have this as ;
Angle DEF = 1/2 * DOF
1/2 * 150 = 75
This is because angle at the center is twice the angle at the circumference

A different camera is selling for $7.50 off the regular price. It was discounted 15%. What was the original price of the camera?
A)$112.50
B)$75.00
C)$50.00
D)$45.00
Answer:
C) $50.00
Step-by-step explanation:
$7.50 is the 15% discount
1% of the original price would be ($7.50 / 15)=0.50
100% of the original price would be 100 x 0.50 = $50.00
Renee and Thomas live at the beach and collect seashells. The number of shells Renee collects on any given day, R, is approximately Normal with a mean of 58.2 shells and a standard deviation of 12.8 shells. The number of shells Thomas collects on any given day, T, is approximately Normal with a mean of 47.9 shells and a standard deviation of 11.5 shells. Assume the two random variables are independent of each other. What is the probability that on a randomly selected day the total number of shells collected by Renee and Thomas is 120 or more? 0.002 0.209 0.284 0.791

Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4
Solve two fifths minus one seventh equals blank.
Answer:
9/35.............,..........
Answer:
1/5
Step-by-step explanation:
2/5 - 1/7 = ???
find the least common denominator!
45 would be the least common demoninator!
so...
2 (7) / 5(7) - 1 (5) / 7 (5) = ?
14/ 45 - 5 /45 = ?
14 - 5 = 9
9/45. Simplify!
9/45 divide 9 from both sides
9/9 / 45/9
= 1/5, one fifths is your answer!

Basil has five numbered cards.
Two of the numbers are hidden. 4 9 9 ? ? 8
The mode of the five numbers is 8.
The mean of the five numbers is 6
c) Work out the two hidden numbers.
Answer:
The two hidden numbers are 8 and 1.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is given by the sum of all its values divided by the number of values.
Mode of a data-set:
The mode of a data-set is the value that appears the most.
In this question:
4, 9, x, y, 8
Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:
4, 9, 8, y, 8
The mean of the five numbers is 6
This means that:
[tex]\frac{4+9+8+y+8}{5} = 6[/tex]
[tex]29+y = 30[/tex]
[tex]y = 30 - 29[/tex]
[tex]y = 1[/tex]
The two hidden numbers are 8 and 1.
sin0=? cos0=? tan1=?
Answer:
See explanations below
Step-by-step explanation:
Sin 0 = x
0 = arcsinx
Since 0 the angle is positive and lies in the 1st and second quadrant, sin 0 = 0 (in the first quadrant)
cos 0 = 1 (by punching the calculator)
tan 1 = 0.0174
All this values can easily be gotten directly from calculators
