Answer:
5.83 cubic feet
Step-by-step explanation:
Volume of block1 :
l = 4 ft
[tex]\sf w = \dfrac{5}{6} \ ft\\\\ h = 1\dfrac{1}{6}=\dfrac{7}{6} \ ft[/tex]
[tex]\sf Volume \ of \ block1 = l*w*h\\[/tex]
[tex]\sf =4 *\dfrac{5}{6}*\dfrac{7}{6}\\\\ =\dfrac{5}{3}*\dfrac{7}{3}\\\\= \dfrac{35}{9} \ cubicfeet[/tex]
Volume of block2:
l = 4 ft
[tex]w = 1\dfrac{2}{3}-\dfrac{5}{6}\\\\ =\dfrac{5}{3}-\dfrac{5}{6}\\\\ =\dfrac{5*2}{3*2}-\dfrac{5}{6}\\\\=\dfrac{10}{6}-\dfrac{5}{6}\\\\w =\dfrac{5}{6} \ ft\\\\h =\dfrac{7}{12} \ ft[/tex]
[tex]\sf Volume \ of \ block2 = 4 *\dfrac{5}{6}*\dfrac{7}{12}[/tex]
[tex]\sf = \dfrac{5}{6}*\dfrac{7}{3}\\\\= \dfrac{35}{18} \ cubicft[/tex]
Amount of concrete to build stairs = Volume of block1 + volume of block2
[tex]\sf = \dfrac{35}{9}+\dfrac{35}{18}\\\\=\dfrac{35*2}{9*2}+\dfrac{35}{18}\\\\=\dfrac{70}{18}+\dfrac{35}{18}\\\\=\dfrac{105}{18}\\\\= 5.83 \ cubic feet[/tex]

If John reaches into the bag and randomly pulls out a marble, what is the probability that the marble will be blue? (If necessary, round to the nearest tenth.) (as a percent please!!)
Answers
Answer:
P(blue) ≈ 14.3%
Step-by-step explanation:
probability P is calculated as
P = ( favourable outcome ) ÷ ( total number of possible outcomes )
here favourable outcome is blue of which there are 3
number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21
P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]
to convert to a percentage multiply the fraction by 100%
P (blue) = [tex]\frac{1}{7}[/tex] × 100% = 100% ÷ 7 ≈ 14.3% ( to the nearest tenth )

You have noticed that because of the pandemic, cycling became popular again
as it became one of the means of transportation for many especially those who
lost their jobs and it became a hobby for some. You became a fan of cycling due
to its influence, so you decided to build your own Mountain bike. You have many
choices to make. First, you must choose the color of your bike from 4 colors (red,
blue, orange, black), second is the seat either normal or with extra cushion and
the last is the handlebar if you want to have a straight one or a curve.
Using the fundamental counting principle, count the number of choices you have
in building your mountain bike?
Answers
Using the Fundamental Counting Theorem, it is found that you have 16 choices in building your bike.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the color, there are 4 outcomes, hence [tex]n_1 = 4[/tex].For the seat, there are 2 outcomes, hence [tex]n_2 = 2[/tex].For the handebar, there are 2 outcomes, hence [tex]n_3 = 2[/tex].Thus, the total number of choices is given by:
N = 4 x 2 x 2 = 16.

Answers
Answer:
Length of diagonal of the rectangle is 21.25 units.Step-by-step explanation:
Here we are given Length of the rectangle 17 and Width 12.75. To find length of the diagonal of the rectangle we will substitute the value of length and width in required formula:
We know that,
[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pink{ \pmb{\mathfrak {Diagonal = \sqrt {(Length)^2 + (Width)^2 }}}}}}} \\ \\ [/tex]

A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound. which equation represents the cost, in dollars, of shipping a package that weighs x pounds?
Answers
The equation is 6(2x-1), where X is more than 0. When a shipping company charges $6 to ship a package that weighs up to 1 pound.
What is the equation?
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound.
lets make an assumption that the total weight of the shipment is x pound and cost for shipping is y.
the shipping company charges $6 for the first pound.
Up to now, the charge is y=6
After 1 pound, i.e for the remaining (x-1) pounds, they charge $2 per pound.
So, the total charge will be, y=6+2(x-1)
weight is always starting from zero as there is no negative weight.so X>0
so the equation is 6(2x-1), where X is more than 0

Answer:

Step-by-step explanation:
Multiplying a function by a constant has the effect of vertically scaling the graph of the function by a factor equal to that constant.
__
Here, you're multiplying by 2/3, so each y-value is 2/3 of its previous distance from the x-axis. The effect on the graph of a parabola is to make it "flatter", hence wider in appearance. This does not change the direction in which it opens.

Answer:
y = (1/4)x + 20
Step-by-step explanation:
The general equation of a line is
y = mx+ b , where m is the slope of the line and b is the y-intercept of the line ( where the line intersects the vertical y-axis)
From the graph we can see that the line intersects the y-axis at 20, so our y- intercept is b = 20
Now will find the slope of the line, and for that we need any two points from the line.
For example let's pick points ( x1= 0, y1 = 20) and ( x2 = 4, y2 = 21)
the slope m = (y2-y1)/(x2-x1) = (21-20)/ (4-0) = 1/4
slope of the line is m = 1/4
The equation of the graph shown in the graph is
y = (1/4)x + 20

The surface area S of a cylinder is S = 2πr² + 2πrh where r is the base radius and h is the height. What is h, in inches, when S is 175 square inches and r is 6 inches?
Answers
Answer:
h = -1.356
Step-by-step explanation:
Remark
This is one of those questions where you could solve for h in the formula and then just put values in for all the other variables. Since you have posted this on Brainly, I'll just use the formula given and my last step will be one of division
Formula
S = 2 * pi * r^2 + 2 * pi * r * h Put the givens into the formula
Givens
S = 175 in^2
pi = 3.14
r = 6
h = ?
Solution
175 = 2 * 3.14 * 6^2 + 2 * 3.14 * 6 * h Combine
175 = 226.08 + 37.68*h Subtract 226.08 from both sides
175-226.08 = 37.68*h Combine
-51.08 = 37,68*h Divide by 37.68
h = - 51.08/37.68
h = -1.356
