Answer:
Sin theta= a/c
= 5/7.8
= 0.64
= 1
Step-by-step explanation:
Lets find the hypotenuse first by applying Pythagorean theorem.
a^2+b^2=c^2
(6)^2+(5)^2=c^2
36+25=c^2
61=c^2 (FIND SQUARE ROOT)
7.8=c
Sin theta= a/c
= 5/7.8
= 0.64
= 1
Cos theta= b/c
= 6/7.8
Tan theta= a/b
= 5/6

Ok. First, let's find the slope using the slope formula.
[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]
4/0 is undefined.
When the slope is undefined, that means that it's a straight line going down from the x.
So the equation is just x = 2
Which electromagnet is the strongest?

A black bar with 4 copper colored coils around it
Answers
Answer:
c
Step-by-step explanation:
A black bar with 7 copper colored coils around it is the strongest.
What is an Electromagnet?Electromagnets are defined as magnet which works through electricity.
We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.
Strength of electromagnet depends on basically two things:
First, the amount of current flowing through the wire and
Second, the number of turns of wire around the coil.
Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.
Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.
Hence, a black bar having 7 copper colored coils around it is the strongest.

Step 1: Simplify both sides of the equation.
[tex]\fbox{9−7y(7)=6+5−3y−416}[/tex]
[tex]\fbox{9+−49y=6+5+−3y+−416}[/tex]

PLEASE HELP ASAP!! an onion soup recipe calls for 3 2/3 cups of chopped onions. katrina has already chopped 1 1/3 cups of onions. She wants to know how many more cups she needs to chop. (I WILL MARK Brainliest for answers with a great explanation and written down solutions to the problem!)
Answers
Answer:
[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]
Step-by-step explanation:
Let the number of cups of onions Katrina still needs to chop = x
She has already chopped the onions = [tex]1\frac{1}{3}[/tex] cups ≈ [tex]\frac{4}{3}[/tex] cups
So total amount of chopped onions = [tex](x+\frac{4}{3})[/tex] cups
Since, onion soup recipe calls for the chopped onions = [tex]3\frac{2}{3}[/tex] cups ≈ [tex]\frac{11}{3}[/tex] cups
Therefore, equation which shows the number of cups of onions to be chopped more will be,
[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]
We further solve this equation for the value of x,
x = [tex]\frac{11}{3}-\frac{4}{3}[/tex]
x = [tex]\frac{(11-4)}{3}[/tex]
= [tex]\frac{7}{3}[/tex] cups
≈ [tex]2\frac{1}{3}[/tex] cups

What is the equation, in point-slope form, of the line
that is perpendicular to the given line and passes
through the point (-4, -3)?
A: y + 3 = -4(x + 4)
B: y + 3 = -1/4(x+4)
C: y + 3 = 1/4(x + 4)
D: y + 3 = 4(x + 4)
Answers
Answer:
C: y + 3 = 1/4(x + 4)
Step-by-step explanation:
Perpendicular to a given line means opposite inverse of the slope...
Equation of line is: y = -4x - 3
slope in above equation is -4, perpendicular would be 1/4
Perpendicular equation of a line through P(-4, -3):
y = mx + b
-3 = 1/4(-4) + b
-3 = -1 + b
b = -2
Use perpendicular slope and the b from above to form the perpendicular equation of line:
y = 1/4x - 2
Check:
(-3) = 1/4(-4) - 2
-3 = -1 - 2
-3 = -3
A pack of 36 milk chocolate candy bars costs $23.20. Each bar weighs 1.6 oz. Calculate how much one pound of these chocolate bars would cost (price per pound)
Answers
Answer:
$6.44
Step-by-step explanation:
First, we have to find out how many total ounces the pack weighs.
Multiply the number of bars by the oz of each bar.
36 x 1.6 = 57.6
Divide the cost of the pack by the total oz
23.2 ÷ 57.6 = 0.40277... (Let's round it to 0.4028)
Multiply the cost per oz to by 16 (16 oz = 1 lb) to get cost per pound
0.4028 x 16 = 6.4448
Round it to the nearest hundredth, and we get that the price per pound is $6.44.
