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:

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:

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

Answer:

12

Step-by-step explanation:

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

15²=9²+x²

x²= 144

X= 12

Answer:

d. 6.4

Step-by-step explanation:

d=√(1−5)2+(−3−2)2

d=√(−4)2+(−5)2

d=√16+25

d=√4–√1

d=6.403124

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

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.

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

Answer: Any real number x as long as [tex]x \ne 0[/tex] and [tex]x \ne -\frac{2}{3}[/tex]

In other words, anything but 0 or -2/3 is valid.

========================================================

Explanation:

Set the denominator equal to zero and solve for x

2(3x^2 + 2x) = 0

3x^2 + 2x = 0

x(3x + 2) = 0

x = 0 or 3x+2 = 0 .... zero product property

x = 0 or 3x = -2

x = 0 or x = -2/3

If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x)  will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.

Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.

Answer:

Can you show me a picture, that would help.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

We have both given slope and y-intercept. We can simply substitute the given slope and y-intercept in slope-intercept form.

Substitute m = -1 and b = - 5 in the equation.

[tex]y = - 1x - 5 \\ y = - x - 5[/tex]

We don't usually write 1x or -1x instead we write -x or x.

[tex]y = - x - 5[/tex]
