The area of a rectangle if the length is 5 more than 4 times the width, what's the algebraic expression for this question
The area of a rectangle if the length is 5 more than 4 times the width, the algebraic expression for this is, A = (4b + 5) × b
What is the area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Given that,
The length is 5 units more than 4 times the width
Suppose,
length = l
width = b
So, according to given condition
l = 4b + 5
Now, the area for rectangle is
A = length × width
A = l × b
A = (4b + 5) × b
Hence, the algebraic expression is (4b + 5) × b

Step-by-step explanation:
d = 2r = 2(2 m) = 4 m
C = πd = 3.14 × 4 m = 12.56 m
Answer:
C=12.56 m
Step-by-step explanation:
The radius is 2 m. To find the circumference, you need d, which is the diameter.
The diameter of a circle is 2 times the radius.
d=2*2=4
Now use the formula to find the circumference
C=3.14*4=12.56

A circular carnival ride has a diameter of 120 ft. Suppose you board a gondola at
the bottom of the circular ride, which is 6 ft above the ground, and rotate 240°
counterclockwise before the ride temporarily stops. How many feet above ground
are you when the ride stops?
Answer:
The height above ground when the ride stops is 96 feet
Step-by-step explanation:
The given diameter of the carnival ride, d = 120 ft.
The height of the ride above the ground, h = 6 ft.
The angle through which the ride is rotated, θ = 240° counterclockwise
Therefore, we have;
The radius of the ride, r = d/2
∴ r = 120 ft./2 = 60 ft.
We note that at 180° rotation, the ride is at the highest point, [tex]h_{max}[/tex] = 6 ft. + 120 ft. = 126 ft.
When the ride rotates a further 240° - 180° = 60° the height drops from the maximum point by y = 60 ft. × cos (60°) = 30 ft., such that the final height above ground is therefore;
h = 126 ft. - 30 ft. = 96 ft.
The height above ground when the ride stops, h = 96 ft.

[tex]38 + 7x - 21 = 9x + 9[/tex]
Combine like terms.
[tex]17 + 7x = 9x + 9[/tex]
Eliminate a x.
[tex]17 = 2x + 9[/tex]
[tex]8 = 2x[/tex]
[tex]x = 4[/tex]
38 + 7x - 21 = 9x + 9
7x + 17 = 9x + 9
Subtract both sides 9
7x + 17 - 9 = 9x + 9 - 9
7x + 8 = 9x
Subtract sides 7x
7x - 7x + 8 = 9x - 7x
8 = 2x
Divide both sides by 2
8 ÷ 2 = 2x ÷ 2

Answer:

Step-by-step explanation:
The various forms of the expression use the relation ...
-5 1/4 = -5 + -1/4 = -(6 -3/4) = -6 +3/4
Of course, the minus sign in a product can be moved around according to the associative and commutative properties of multiplication.
(8)(-5 1/4)
= (8)(-5 + -1/4)
= 8(-5) +8(-1/4)
= 8(-5) -8(1/4)
= 8(-6 +3/4)

A large bacterium measures 750 micrometers in diameter. One micrometer = 10 − 6 meters. How would you express the diameter of the bacterium in meters using scientific notation? A. 7 . 5 × 10 − 8 B. 750 × 10 − 6 C. 75 × 10 − 5 D. 7 . 5 × 10 − 4
Answer:
7.5 * 10^-4
Step-by-step explanation:
To express this, we will have to multiply 750 by the conversion unit
we have this as;
750 * 10^-6
750 = 7.5 * 10^2
so we have;
7.5 * 10^2 * 10^-6
= 7.5 * 10^(-6+2)
= 7.5 * 10^-4
The diameter of the bacterium in meters using scientific notation is 7.50 × 10^-4
Length of the bacterium = 750 micrometersOne micrometer = 10^-6How to write scientific notationMove the decimal point in between the first and second numberCount the number of digits after the decimal pointDiameter of the bacterium in scientific notation = 7.50 × 10²
Recall one micrometer = 10^-6
So
7.50 × 10² × 10^-6
= 7.50 × 10^(2-6)
= 7.50 × 10^-4

Answer:
Angle 5 = 37°
Angle 8 = 143°
Step-by-step explanation:
Angle 2 = Angle 8
Reason : Alternate exterior angles are equal.
Therefore,
Angle 8 = 143°
Angle 5 + Angle 8 = 180°
Reason : Angle 5 & 8 are in a linear pair.
Angle 5 + 143° = 180°
Angle 5 = ( 180 - 143 )°
Angle 5 = 37°

Evaluate the expression for a = 3, b = 4, and c = 6
a^3 - b + c
Answer:
3^3 - 4+6 = 17
Step-by-step explanation:
First you would do the exponents. 3 to the power of 3 (3^3) is 27.
Then you would add 4 and 6 (4+6) which will give you 10.
Finally, you would need to subract 10 from 27 (27-10) and you would get 17.
Hope this helps! :)
Answer:
29
Step-by-step explanation:
The expression is
a^3 - b + c
You just have to plug in the numbers, then evaluate,,
(3)³ - (4) + (6)
Let's start off with the exponent, so (3)³ = 3×3×3
3×3=9
9×3=27
Now, we have 27 - (4) + (6)
We have to get rid of the parenthesis so multiply the symbol next to it, - × 4 = -4, and + × 6 = +6. Now rewrite the equation.
27 - 4 + 6
27 - 4 = 23
23 + 6 = 29
Therefore, the answer its 29.

6. Nicole earned $72 in 9 hours At this rate, how
much would she earn in 12 hours?
Answer:
96
Step-by-step explanation:
Because 72/9 = 8 so every hour she earns 8$
8*12=96
The amount of money in dollars earned by Nicole in 12 hours will be $96.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Nicole earned $72 in 9 hours. Then the amount of money in dollars earned by Nicole each hour is calculated as,
Rate = $72 / 9
Rate = $8 for each hour
At this rate, the amount of money in dollars earned by Nicole in 12 hours will be calculated as,
⇒ $8 x 12
⇒ $96
The cash in dollars acquired by Nicole in 12 hours will be $96.

Answer:
C = 112, A = 150, D = 30, B = 38
Step-by-step explanation:
I solved C first using:
30+38+c = 180 (angles along a straight line should add up to 180 since a whole circle is 360)
-
I solved A by looking across from C.
Angles on opposite sides should mirror each other but A includes 38* + C
Just by doing 112 + 38 you get 150.
-
I solved D by looking at 30*, alternative interior angles are the same so D is 30*.
-
I solved B by taking C (112) and D (30) and adding them together and subtracting from 180.
Interior angles of a triangle should all add up to 180,
112 + 30 + B = 180
From this I got that B was 38.
Alternatively you can find this out by looking at the 38 degrees, corresponding congruent angles are always the same.
I suggest reviewing this angles sheet if you're ever stuck in the future.

A city council consists of sevenseven Democrats and eighteight Republicans. If a committee of fivefive people is selected, find the probability of selecting twotwo Democrats and threethree Republicans.
Answer:
The probability of selecting two Democrats and three Republicans is 10.7%.
Step-by-step explanation:
Given that a city council consists of seven Democrats and eight Republicans, if a committee of five people is selected, to find the probability of selecting two Democrats and three Republicans the following calculation must be performed:
7 = 100
2 = X
2 x 100/7 = X
28.57 = X
8 = 100
3 = X
3 x 100/8 = X
37.5 = X
0.2857 x 0.375 = X
0.107 = X
0.107 x 100 = 10.7
Therefore, the probability of selecting two Democrats and three Republicans is 10.7%.
