3(2x - 8) > 4x + 26?
Answers
Answer:
x > 25
Step-by-step explanation:
3(2x−8)>4x+26
Step 1: Simplify both sides of the inequality.
6x−24>4x+26
Step 2: Subtract 4x from both sides.
6x−24−4x>4x+26−4x
2x−24>26
Step 3: Add 24 to both sides.
2x−24+24>26+24
2x>50

Answer:
x = 122°
Step-by-step explanation:
since it is a right triangle, the sum of the other 2 interior angles = 90°
the angle opposite x = 90° - 32° = 58°
58° and angle x are supplementary angles. Their sum is 180°.
180° - 58° = 122°

cos s=-2/5 and sin t=4/5, s and t are in quadrant II
find cos(s+t) and cos(s-t)
Answers
Answer:
•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25
•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25
cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗
sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5

help me find the rate of change
Answers
Answer:
3
Step-by-step explanation:
To find the rate of change, we want to use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values using two given points. I will use the first and last points.
(1, -2) & (13, 34)
(34 - (-2)) / (13 - 1)
Simplify the parentheses.
= (34 + 2) / (12)
= 36/12
Simplify the fraction.
36/12
= 3
This is your slope.

P(x)=0.2x^2+20x-4 where x is the number of units sold. How many units need to be sold for the business to make a profit of $101?
Answers
Answer:
5
Step-by-step explanation:
Given the profit equation ;P(x)
x = number of units sold
P(x) = profit made
P(x) = 101
101 = 0.2x^2+20x-4
0.2x^2+20x-4 - 101
0.2x² + 20x - 105 = 0
Using the formula:
-b±[sqrt(b² - 4ac) / 2a]
Where ;
a = 0.2 ; b = 20, c = - 105
Using the quadratic equation solver to save time :
The roots are :
-105 and 5
Items sold cannot be negative ;
Hence, x = units sold = 5

Loki wrote 1/6 of a page in 1/12 of a minute. How much time does it take him to write a full page?
Answers
EXPLANATION:
To find the answer, we can find an equivalent fraction for each.
1/6 x 6 = 6/6
1/12 x 6 = 6/12
So every 1 minute Loki writes half a page.
Since 2 halves = 1.
2 minutes for 1 page.

Answer:
trapezoid.
Step-by-step explanation:
A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs
Characteristics of a trapezoid
It has 4 vertices and edges
If both pairs of its opposite sides of a trapezoid are parallel, it becomes a parallelogram
Area of a trapezoid = [tex]\frac{1}{2}[/tex] x (sum of the lengths of the parallel sides) x height
Perimeter = sum of lengths of sides of a trapezoid

Sloths climb through the canopy while hanging upside down. If it takes a sloth 10 minutes to climb 7.5 feet, what's its climbing speed in miles per hour?
Answers
Answer:
0.00852 miles per hour
Step-by-step explanation:
Given that:
Distance = 7.5 feets
Time taken = 10 minutes
Speed = distance / time taken
Speed = 7. 5 feets / 10 minutes = 0.75 feets / minutes
Converting to miles per hour :
0.75 feets / minute :
1 mile = 5280 feets
1 minute = 1/60 = 0.0166666 hour
0.75 feets / minute = (0.75/5280)mile / 0.0166666
= 0.0001420 / 0.0166666 mile per hour
= 0.0085200 miles per hour
= 0.00852 miles per hour

Stephanie wants to make 22.5 qt. of a 20%
alcohol solution by mixing together a 6%
alcohol solution and a 36% alcohol solution.
How much of each solution must she use?
Answers
Answer:
y = 10.5qt
x = 12 qt
Step-by-step explanation:
0.6x+ 0.36y = 22.5 * 0.2
0.06x + 0.36y = 4.5
x + y = 22.5
x = 22.5 - y
0.06(22.5 - y) + 0.36y = 4.5
1.35 - 0.06y + 0.36y = 4.5
0.3y = 4.5 - 1.35
0.3y = 3.15
y = 3.15 / 0.3
y = 10.5 qt
x = 22.5 - y
x = 22.5 - 10.5
x = 12 qt
