What is the volume of a hemisphere with a diameter of 8.9 cm,
Answers
Answer:
The volume of the hemisphere is 1,475.73cm^3.
Step-by-step explanation:
Refer to:
https://brainly.com/question/23826439
184.6cm³ up you are rounding to the nearest tenth 184.56cm³ if you are rounding to the nearest hundredth
It's a hemisphere instead of a sphere so the formula is 2/3×π×r³ which gives us the equation of 2/3×π×4.45³ snd the reason we use 4.45 is because the diameter is 8.9 so we have to divide that by 2 to get the radius which is 4.45

4x + 2y = -12 3x + y = -10 please help system by substitution.
Answers
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)

Answer:

2.
[tex]y=-\frac{1}{3}x+1[/tex]
m= [tex]-\frac{1}{3}[/tex]
b= 1
3.
[tex]y=3x+4[/tex]
m= 3
b=4
Step-by-step explanation:
1. The line intersects the y-axis at the point (0,2) therefore its y-intercept is b=2.
The line rises up 1 unit on the y-axis for every 4 units on the x-axis therefore the line has a slope of m=1/4.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=\frac{1}{4}x+2[/tex]
2. The line intersects the y-axis at the point (0,1) therefore its y-intercept is b=1.
The line down up 1 unit on the y-axis for every 3 units on the x-axis therefore the line has a slope of m= -1/3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=-\frac{1}{3}x+1[/tex]
3. The line intersects the y-axis at the point (0,4) therefore its y-intercept is b=4.
The line rises up 3 units on the y-axis for every 1 unit on the x-axis therefore the line has a slope of m=3.
Considering the equation of a line (y=mx+b), we plug in the variables we have found into the formula to find that [tex]y=3x+4[/tex]

Answer:
The answer will be -5a-4
Step-by-step explanation:
Subtract 7a-12a=-5a
Add -8+4=-4
which makes the answer -5a-4
Hope this helps:)
Answer:
a = -4/5
Step-by-step explanation:
7a - 8 - 12a + 4
First, you want to put like terms together. You can rearrange the terms because of the Commutative Property.
7a - 12a - 8 + 4
I will put parentheses around the negative numbers, so it is easier to see the negative numbers.
7a (- 12a)( - 8) + 4
Now you combine the Like Terms
7a-12a and -8+4
- 5a - 4
Now you need to get the term with a all by itself on the other side of the equals sign. You can do this by adding the term over to the other side.
-5a - 4
+5a +5a
Now you have
- 4 = 5a
To get the final answer you need to get a all by itself. You can do this by dividing 5 on both sides.
-4/5=5a/5
So you get
-4/5 = a
as your final answer.
Explain how to tell which side of a right triangle is adjacent to an angle and which side is the hypotenuse.
Answers
Step-by-step explanation:
In the diagram, AB is adjacent to Angle"a", because if we don't consider hypotenuse, it is the only associated segment to the angle.
The segment opposite to the right angle is called Hypotenuse.
The last one, AC segment, is called the Opposite because it is the opposite to Angle"a".
If we look at it from AngleC, however, its Adjcent will be segment AC, and Opposite will be segment AB.

Answers
Answer:
Length will be 46 ft and width will be 16 ft
Explanation:
Let the width be x.
then the length will be 3x - 2
using the rectangle perimeter formula:
2( length + width )
2(x + 3x-2) = 124
2(4x-2) = 124
8x - 4 = 124
8x = 128
x = 16 ft

The equation of a leftward parabola is [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]. Then the correct option is D.
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called the focus, and the non-movable line is called the directrix.
The parabola is open to the left.
We know that the equation of the parabola will be in square form.
a. [tex]\rm (x - 4)^2 = 4(y +3)[/tex]
This is an equation of an upward parabola.
b. [tex]\rm (x - 4)^2 = -4(y+ 3)[/tex]
This is an equation of a downward parabola.
c. [tex]\rm (y - 4)^2 = 4(x+ 3)[/tex]
This is an equation of a rightward parabola.
d. [tex]\rm (y - 4)^2 = -4(x+ 3)[/tex]
This is an equation of a leftward parabola.

At McDonald's four cheeseburgers
and three medium fries have a
total of 2290 calories. Six
Cheeseburgers and twomedium
fries have 2560 calories.
How many calories doeseach item
contain?
Answers
Y= mediun fries
4x+3y=2290
6x+2y=2560
We want to solve fries first so we multiply the top with 2 and the bottom with -3
8x+6y=4580
-18x-6y=-7680
Now we reduce
-10x=-3100
Now we must divide by -10
X= 310
Cheeseburgers are 310calories
Now just input that in one of the equations
4x+3y=2290
4*310+ 3y=2290
1240+ 3y= 2290
Change the place of 1240
3y=2290-1240
3y=1050
Now divide by 3
Y=350
Fries have 350calories
