Answer:
The answer is D. x=-1/2
Step-by-step explanation:
multiply the parantheses by 10 that'll give us 20x-40=100x2. move terms, that'll give us 20x-100x=403. subtract 100x from 20x, that'll give us -80x=404. divide both sides by -80, which is x=-1/2Answer:
D. x = -1/2Step-by-step explanation:
10(2x - 4) = 100x1. Divide both sides by 10.
10/10 (2x - 4) = 100x/102x - 4 = 10x2. Add 4 to both sides.
2x - 4 +4 = 10x + 42x = 10x + 43. Subtract 10x from both sides.
2x - 10x = 10x + 4 - 10x-8x = 44. Divide both sides by -8.
-8x/-8 = 4/-8x = -1/2The answer is D.
please help!! Solve for the hypotenuse and then determine the ratios below. (Show all work)
Answer:
Hypotenuse:
sin x° =
cos y° =
The hypotenuse of the right triangle is 29 units.
The ratios are as follows:
sin x = 20 / 29
cos y = 20 / 29
What is a right angle triangle?Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios. The sides can also be solved using Pythagoras theorem.
The hypotenuse side is the longest side of a right angle triangle.
Therefore,
c² = a² + b²
c = √20² + 21²
c = √400 + 441
c = √841
c = 29
hypotenuse = 29 units
sin x = opposite / hypotenuse = 20 / 29
cos y = adjacent/ hypotenuse = 20 / 29

?= 35.66º
Step-by-step explanation:
26/32=0.8125
cos 35.66º=0.8125
Answer:
? = 36 degrees
Step-by-step explanation:
Use trigonometry!
since we know the adjacent and hypotenuse sides, use cos.
cos(?) = adjacent/hypotenuse = 26/32
? = arccos(26/32)
? = 35.659
Rounding it up, we get.

Jakob buys lunch at school on Mondays, Wednesdays, and Thursdays. He spends $3.50 for each lunch. Which equation
can be used to find the number of weeks, w, it will take Jakob to spend $84 on lunch?
3.50w-84
O (3x3.50)-84
3w-84
(3+3.50)w-84
Step-by-step explanation:
its say $3.50 each so for a week you multiply $3.50 by 3 because the are 3 days which will be equal to $10.5
the you divide $84 by $10.5

Answer:
Statistical Inference
Step-by-step explanation:
Statistical analysis has two main focuses: descriptive statistics and infernetial statistics.
Descriptive statistics summarise data using graphs and summary values such as the mean and interquartile range. Descriptive statistics can help us identify relationships and patterns. Descriptive statistics do not draw conclusions beyond the data we already have. Inferential statistics anaylsis does allow us to make conclusions beyond the data we have.

Step-by-step explanation:
A rectangular prism has a volume of 240 cubic feet. If the length is 4 feet and the width is 4 feet, what is the height of
the prism?
Answer:
Let's use the formula for the volume of a rectangular prism;
V = l · w · h
Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)
What we know:
Volume = 240 ftLength = 4 ftWidth = 4 ftWhat we need to find out:
HeightLet's plug in what we know into the formula:
V = l · w · h
240 = 4 · 4 · h
Now let's solve for h:-
240 = 16 · h
240 = 16h
Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.
÷16 ÷16
Finally, you would end up with a result of:
15 = h
Hence, the height of this prism is 15 feet.
Jaylynn draw a hen on graph paper using scale of 1 unit on her graph paper represents 5cm.The hen has height of 11 units in the drawing.
What is the height,in cm,of the actual hen?
Answers:
A.33
B.44
C.55
D.66
Answer:
55
Step-by-step explanation:
There are 11 units used on the paper. If each unit is 5cm, that means you can do 11*5 and get 55 cm.
Answer:
55
Step-by-step explanation:
1 unit = 5cm
we need to find out how much 11 units are so,
we multiply both sides: 1 unit *11 = 5cm*11, 11 units = 55 cm
