Answer:
m = 1 and b = 5/7
Step-by-step explanation:
Take two of the points. The first two. (7, 5) and (8, 6).
We can find the slope using:
y2-y1/x2-x1
We can sub in the values:
6-5/8-7 = 1/1 = 1
So the slope is 1
now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:
5 = (1)(7) + b
b = 5/7
Therefore, m = 1 and b = 5/7

55% of the cookies Joel baked had chocolate chips. If Joel baked 77 cookies with chocolate chips, how many cookies did he bake?
Answers
Answer:
140 cookies
Step-by-step explanation:
To solve this question all we have to do is divide 77 by 0.55
Why 0.55 because 0.55 is the decimal version of 55%
once we divide 77 by 0.55 that will give us our answer of 140 cookies.
Now to check our answer:
If Joel made 140 cookies and 77 of those cookies are chocolate chip that would leave us with 63 cookies without chocolate chips. If we estimate our answer then 63 cookies would make total sense since we know that 55% = 77
then the other 45% would have to equal around 60-70 cookies

Isabella drives at a constant 45 miles per hour is she drives for why miles and it takes her X hours what is the two variable equation to represent the number of miles isabella Drive Annex hours
Answers
Answer:
Required two variable relation is 45x =y
Step-by-step explanation:
Speed of isabella car is v = 45 miles per hour
now, According to question she takes Y miles( = distance) in X hours (= time)
from The relation of velocity i.e.
velocity = [tex]\frac{distance}{time }[/tex]
on substituting the values in the above relation we get,
v = 45 = [tex]\frac{y}{x}[/tex]
on further rearranging of terms we get,
[tex]45x[/tex] = y
HENCE, required relation is 45x =y , which is a two variable equation.

(-8) is the missing value here, so
the coordinates will be (-8,8)
Answer:
-8
Step-by-step explanation:
→ Substitute y = 8 into -4x - y = 24
-4x - 8 = 24
→ Add 8 to both sides to isolate -4x
-4x = 32
→ Divide both sides by -4 to isolate x
x = -8

3b. If the profile picture of Mark's sister is 3.5 inches tall, how tall is her actual height?
Her actual height is _____ inches.
70
82
59.5
66.5
Answers
Step-by-step explanation:
Answer: 19, because all you´re doing for mark is dividing his actual height from the profile picture.
Marks sister: 66.5, because you will take her height (3.5) and you will put x over 3.5 in fraction form. Then you will take marks profile picture height, and put it in fraction form (76 over 4) then you will cross multiply 3.5 and 76 which will give you 266. Then you´ll divide 266 by 4 which would give you 66.5

You have a 12 inch ruler being used as a miniature seesaw. A pencil is placed under the 4 inch mark. A weight is placed at the 2 inch mark that balances the seesaw. Now the uneven seesaw is balanced. if you then placed a pencil at the 12 inch end, how many similar pencils approximately will you need to place at the other 1 inch end to get a balance again?
Answers
Answer:
The number of pencils that needs to be placed at the other 1 inch end to get a balance again is approximately 3 pencils
Step-by-step explanation:
The given parameters are;
The length of the ruler used as a seesaw = 12 inch
The location where the pencil is placed = Under the 4 inch mark
The location where the weight is placed to balance the seesaw = The 2 inch mark
Therefore, the pencil at the 4 inch mark is fulcrum
The location where a pencil is placed on the ruler = The 12 inch end
The number of pencils, x, that needs to be placed at the other 1 inch end to get a balance again is given as follows;
The distance of the pencil at the 12 inch end from the fulcrum = 12 inches - 4 inches = 8 inches
The distance of the pencils placed at the 1 inch end from the fulcrum = 4 inches - 1 inch = 3 inches
Therefore at balance point, (equilibrium) the anticlockwise moment = The clockwise moment, which gives;
The mass of 1 pencil × 8 inches = x × The mass of 1 pencil × 3 inches
x = (The mass of 1 pencil × 8 inches)/(3 inches × The mass of x × 1 pencil)
x = 8/3 = 2.[tex]\overline 6[/tex] ≈ 3 pencils
The number of pencils that needs to be placed at the other 1 inch end to get a balance again = x ≈ 3 pencils.

Step-by-step explanation:

[tex]\frac{8}{12}[/tex] = [tex]\frac{x-3}{x}[/tex] ( cross- multiply )
12(x - 3) = 8x
12x - 36 = 8x ( subtract 8x from both sides )
4x - 36 = 0 ( add 36 to both sides )
4x = 36 ( divide both sides by 4 )

thanks in Advance
Answers
Answer:
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:
Area of a square:
(Side length)² = 22² = 484 square inches
Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches
Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97

ANSWER:
sin41 × 13.5 = 8.85679
rounded to 3 sig fig
= 8.57
Answers
Answer:
8.86 cm
Step-by-step explanation:
The sine rule shows the relationship between the sides of a triangle and its opposite sides. Sine rule states that given a triangle with side a and opposite angle A, side b and opposite angle B, side c and opposite angle C then:
[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
From the image attached, let AB = x, its opposite angle is 41°. BC = 13.5 cm and its opposite angle is 90° (right angle). Therefore using sine rule:
[tex]\frac{x}{sin(41)} =\frac{13.5}{sin(90)} \\\\x=sin(41)*\frac{13.5}{sin(90)}\\\\x=8.8568\\\\ x=8.86\ cm\ to\ 3\ s.f[/tex]
x = AB = 8.86 cm

so a^2 + b^2 = c^2
c^2 is the hypotenuse and the 15 feet
a^2 + 9^2 = 15^2
a^2 + 81 = 225
a^2 = 144
the square root of 144 is 12
the tree is 12 feet tall

12

if you draw the picture in your copybook you will see that there is a right triangle, we have the Pythagorean theorem i.e c=√a²+b²
15=√9²+x². the trees tall=X

write an equation of a line that is parallel to y=3x-2 and runs through the point (1,6)
Answers
Answer:
y=3x+3
Step-by-step explanation:
If equations of lines are parallel, their slopes are the same. Therefore, we can sub '3' in for the slope value in y=mx+c to get y=3x+c.
Sub in the point:
6=3(1)+c
c=6-3=3
ANS: y=3x+3
Answer:
y = 3x + 3
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 = 3x - 2 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, so
y = 3x + c ← is the partial equation
To find c substitute (1, 6) into the partial equation
6 = 3 + c ⇒ c = 6 - 3 = 3
y = 3x + 3 ← equation of parallel line
