(4m+3)(m+2)
expand each of the following algebraic expression
Answer:
4m² + 11m + 6
Step-by-step explanation:
Use foil to expand this value.
(4m+3)(m+2)
Multiply the first terms in the two brackets.
Then multiply the two outer terms.
Followed by multiplying the inner terms.
Finally multiply the last terms
= (4m+3)(m+2)
4m² + 8m + 3m + 6
4m² + 11m + 6
At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 12 m. The inner edge of the sidewalk is a circle with a radius of 8 m.
Write and simplify an expression for the exact area of the sidewalk.
Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answer:
The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m
The equation would be:
144 x 3.14 - 64 x 3.14 = 251.2
Step-by-step explanation:
First, you need to find out what the whole circle is:
The whole circle is 452.16
Then, find the inner circle :
8 x 8 x 3.14
200.96
Last, subtract the whole by the inner:
452.16 - 200.96 = 251.2

The diagram shows two right-angled triangles. Calculate the value of x.
The value of x in the given diagram is 7cm.
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
According to the given question.
We have a diagram in which we have two right angled triangles.
Now, in the upper right angled triangle
[tex]tan50 = \frac{0pposite side}{5}[/tex]
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side w.r.t angle 50 degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
[tex]tan38 = \frac{x}{adjacent side}[/tex]
⇒[tex]0.78 = \frac{x}{6}[/tex]
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.

A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a gift. What measurement is closest to the amount of wrapping paper needed to cover the container without overlap?
Answer:
Step-by-step explanation:
1. Write your formula
2. Plug it in
3. Solve
these steps will help you out with all of your surface area problems.
Like this
Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...
V = Bh (Pie is also known as 3.14)
your big (B) is (pie times r squared) Then you add your height.
so your formula will look like this...
V = pie times r squared...
the full formula will be...
V = (3.14) times (2.5 squared) times the height which in this case is (12)
everything together will be...
V = (3.14) (2.5^2) (12)
all you have to do is multiply all of that and you will get your answer.
The answer is...
V = 236 inches ^2 (Just a tip, the ^ sign means to the power of)

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388

Answer:
If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341) Don't forget units in your work and answer.
Step-by-step explanation:
Volume of Rectangular prism = L*W*H = 8*10*16 = 1280in
Volume of Cylinder = pi*r^2*H = 8*pi*r^2
We know that the diameter is 8 (because that's the height of the rectangular prism as stated in the question) and diameter is 2*r thus the radius of the cylinder is 4.
therefore the volume of the cylinder is 8*pi*(4)^2 which is 128pi If you aren't allowed to use calculators do (1280 - 128pi) but if you are do (877.876140341)

Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
[tex] = > x = \frac{75}{5} [/tex]
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = 25 (Ans)

According to the properties of inequality, when should the inequality symbol be reversed when solving a two-step inequality in the form below?
a x + b greater-than c
when a is positive
when a is negative
when b is positive
when b is negative
Answer:
B. when a is negativeStep-by-step explanation:
Inequality given:
ax + b > cWhen solving we do steps:
ax > c - bx > (c - b)/aAt the second step both sides divided by a.
When a is positive the inequality symbol remains as is, when a is negative we have to divide both sides by -1 as well. This will reverse the inequality symbol.
Correct answer choice is B.
