Find the area of the trapezoid.
A. 15 cm2
B.18 cm2
C.21 cm2
D. 35 cm2
Answer:
B. 18 cm²
Step-by-step explanation:
The area of a trapezoid can be found using the formula ...
A = 1/2(b1 +b2)h
For the given dimensions, the area is ...
A = 1/2(7 cm +5 cm)(3 cm) = 1/2(12)(3) cm² = 18 cm²
write the linear equation of a line that passes through (2 5) and (2 9)

(2, 5) and (2, 9)
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 table represents a nonlinear function?
Answer:
I think D though I'm not sure
Step-by-step explanation:
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)
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)
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.

Answer:
The the equation of the line through the points (8, -2) and (5, 5) in slope-intercept form is
Step-by-step explanation:
Let's start by calculation the slope of the line by finding the slope of the segment that joins the two given points (8, -2) and (5, 5):
Now we use this slope in the general slope-intercept form of a line;
and then we calculate the value of the intercept "b" by using one of the given points through which the line must pass (for example (5,5) ), and solving for b:
The the equation of the line is
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!)
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
Answer:
x+1 1/3 = 3 2/3 *Which x is 2 1/3

Which electromagnet is the strongest?
A black bar with 5 copper colored coils around it.
A black bar with 2 copper colored coils around it.
A black bar with 7 copper colored coils around it.
A black bar with 4 copper colored coils around it
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.

Identify the value of y.

pls help
Hey there!
Let's solve your equation step-by-step.
[tex]\fbox{9−7y(7)=6+5−3y−416}[/tex]
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]
[tex]\fbox{−49y+9=(−3y)+(6+5+−416)}[/tex](Combine Like Terms)
[tex]\fbox{−49y+9=−3y+−405}[/tex]
[tex]\fbox{−49y+9=−3y−405}[/tex]
Step 2: Add 3y to both sides.
[tex]\fbox{−49y+9+3y=−3y−405+3y}[/tex]
[tex]\fbox{−46y+9=−405}[/tex]
Step 3: Subtract 9 from both sides.
[tex]\fbox{−46y+9−9=−405−9}[/tex]

then descends(down) 40 meters. What is the submarine's new position relative to sea
level?
Answer:
65 meters below sea level
Step-by-step explanation:
so we can do one of 2 things, either 37-12+40, or -30+12-40, either way will give you the 65, just one will be a negative. obviously the submarine is going down, so if you do the positive way, just remember that it is negative.
