i am trying to solve question two with the graphing method but can’t figure out how because there is only y=2.
Answers
Answer: look in the explanantion :)
Step-by-step explanation:
So basically when something is y=2, that means that its just a horizontal line at the number 2
so it would just be a straight horizontal line that is located at the y point of 2

If 24 marbles have a mass of 60g what would be the mass of 60 marbles
Answers
Answer:
300 g
Step-by-step explanation:
First divide the mass of those 12 marbles (60 g) by the number of marbles which have 60 g mass (12 marbles). You'll get the answer as 5 g , which means 5 g is the mass of 1 marble. Now multiply the answer by 60 (specification of marbles). You'll have the answer as 300 g.
i.e.
60 / 12 = 5
5 x 60 = 300

can someone explain the meaning of surface area and give me an example of it is
Answers
Answer:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. ... Their work led to the development of geometric measure theory, which studies various notions of surface area for irregular objects of any dimension. An important example is the Minkowski content of a surface.
The total area of the surface of a three-dimensional object. Example: the surface area of a cube is the area of all 6 faces added together. See: Area.

There are 520 marbles in a jar. The ratio of red to yellow marbles is 3:4 and the ratio of yellow to blue marbles is 2:3. What is the total number of yellow and blue marbles?
Answers
Answer:
Step-by-step explanation:
Change the 2/3 to 4/6
Now the ratio becomes 3:4:6
So the number of each is
3x + 4x + 6x = 520
13x = 520
x = 40
Red = 3*40 = 120
Yellow = 4*40 = 160
Blue = 6 * 40 = 240
Total = 520
What is the equation in slope-intercept form of the line that passes through the
point (2,-2) and is perpendicular to the line represented by y = x +2?
Answers
Answer:
[tex]y=-x[/tex]
Step-by-step explanation:
The slope-intercept form of a line can be written as [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope, [tex]b[/tex] is the y-intercept, and [tex](x,y)[/tex] are the coordinates of any point that this line passes through.
Perpendicular lines have negative-reciprocal slopes. Therefore a line perpendicular to [tex]y=x+2[/tex] will have a slope of [tex]-\frac{1}{1}=-1[/tex].
Now that we have a slope and coordinates of a point that the line passes through, we can solve for the y-intercept and the equation of the line:
[tex]-2=-1(2)+b, \\b=0[/tex]
Thus, the equation of this line is [tex]\fbox{$y=-x$}[/tex].

Billy likes to go cycling. His bike has wheels of the diameter 70 cm. He has a counter on his bike which counts the number of revolutions of the wheels make. One day the counter shows 190 revolutions. How far has Billy cycled? Give your answer to the nearest meter.
Answers
Answer:
401 meters
Step-by-step explanation:
To change the units without changing the value, we use the Multiplicative Identity (that is, 1).
The formula for the circumference of a circle is: C=Πd
The problem gives d=85 cm, so C=85Π cm. So, (1 revolution)=(85Π cm)
or 1= (85Π cm) / (1 revolution)
Billy traveled:
150 revolutions
(150 revolutions)*1
(150 revolutions) * ( (85Π cm) / (1 revolution) ) [note: revolutions cancel, leaving only cm]
(150)*(85Π) cm
40055.27 cm * ( (1 meter)/(100 cm) )
401 meters (rounded to nearest meter)

Directions: Find all missing angles.
Answers
Answer:
m<1 = 87°
m<2 = 45°
m<3 = 45°
m<4 = 52°
Step-by-step explanation:
Angle C is a right angle. Therefore, it is 90°. Because line segment BC bisects angle C, the two angles would be 45° since 90 ÷ 2 = 45.
So, angles 2 and 3 equal 45°.
Now that we have two angle measures, we can find the measure of the third angle.
45 + 48 = 93°
180 - 93 = 87°
Angle 1 equals 87°.
45 + 83 = 128°
180 - 128 = 52°
Angle 4 equals 52°.

What number is 115% of 106? (Show your work)
Answers
2. We assume, that x is the value we are looking for.
3. If 100% equals 106, so we can write it down as 100%=106.
4. We know, that x% equals 115 of the output value, so we can write it down as x%=115.
5. Now we have two simple equations:
1) 100%=106
2) x%=115
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=106/115
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 115 is what percent of 106
100%/x%=106/115
(100/x)*x=(106/115)*x - we multiply both sides of the equation by x
100=0.92173913043478*x - we divide both sides of the equation by (0.92173913043478) to get x
100/0.92173913043478=x
108.49056603774=x
x=108.49056603774
now we have:
115 is 108.49056603774% of 106
Answer:
121.9
Step-by-step explanation:
1% of 106 = 1.06
1.06 x 15 = 15.9
106 + 15.9 = 121.9

Anthony downloaded 8 total items onto his phone. The games he purchased were $2.00 each and songs were $1.00. How many of each did he buy after spending $11.00?
Answers
Answer:
he downloaded 9 songs and 1 game
Step-by-step explanation (3x2= 6) (5x1= 5) (3+5= 8) $6.00 + $5.00 = $11.00
so add 3 items to the games that would be $6.00 so 5 items would remain put the rest of those items into the music that would be 5x1 =$5.00. So $6.00+$5.00= $11.00 so the answer is $11.00.

Answer:
y = - 2x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{2}[/tex] x - 8 ← is in slope- intercept form
with slope m = [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute (- 3, - 4) into the partial equation
- 4 = 6 + c ⇒ c = - 4 - 6 = - 10
y = - 2x - 10 ← equation of perpendicular line
Step-by-step explanation:
Hey there!
The 1st equation is;
y= 1/2 x-8.............(i)
Comparing the equation y= mx+c. We get;
Slope (m1) = 1/2
The equation of point which moves through point (-3,-4).
(y-y1) = m2 (x-x1). {Use one-point formula to find out the equation}
(y+4) = m2 (x+3)..………(ii)
Now, we need to find m2.
So, the condition of perpendicular lines: m1*m2= -1.
[tex] \frac{1}{2} \times m2 = - 1[/tex]
[tex]m2 = - 2[/tex]
Therefore, m2 = -2.
So, let's keep value of m2 in eqaution (ii).
y+4 = -2(X+3)
y+4 = -2x-6
y = -2x -10.
Therefore, the eqaution is y= -2x-10.

Xavier starts the summer with $315 in his savings account. Since he will be working a lot this summer, he made plans to deposit $80 into his account each week. If he ended the summer with $955 in his savings account, how many weeks did he make deposit?
Answers
Answer: 8 weeks
Step-by-step explanation:
He originally had $315 in his account. This figure increased to $955. It therefore increased by:
= 955 - 315
= $640
If he deposited $80 every week, the number of weeks it would take to deposit $640 is:
= 640/80
= 8 weeks

The number of bricks needed to border the circular pool is 6.28r.
The circumference of a circle is the distance around the circle which is 2πr.
The diameter of a circle is the largest chord that passes through the center of a circle it is 2r.
Given, Mr. Cortez is putting a brick border around his circular pool.
So, he is boarding the circumference of the circular pool which has a distance of 2πr.
Now, the bricks are 1 foot in length.
Therefore, the number of bricks needed is,
= 2πr/1
= 2πr
= 6.28r
Therefore, the number of bricks James need to buy to build the border is 6.28r.
