Round to the nearest integer, if necessary.
times.
You will roll a number less than 4 about
Answer:
100 times
Step-by-step explanation:
you have a 3/6 chance of rolling less than 4 once
so you multiply 3/6 times 200- you get 600/6
you simplify 600/6 to 100
100 times is the answer.

A bird sanctuary has 14 bags of bird seed. Each bird feeder holds 1/6 of a bag. How many bird feeders can be filled with the bird seed?
Answer:
84 bird feeders can be filled
Step-by-step explanation:
Considering there is 14 bags, all you'd have to do is see how many bird feeders can be filled... and to do that, just multiply 14 x 6, because it every bag fills up 6 feeders. 14 x6 =84 bird feeders can be filled.
What is the perimeter of thsi shape ??!
Answer:
D. 180 mm
Step-by-step explanation:
At the bottom of the shape, we can see the base is 60mm. The next side(left or right) is shown as 20mm. The next side right before the missing piece is 20mm. The width of the missing piece is 10mm. The length of the missing piece is 20mm because:
20 + 20 = 40
60mm - 40mm = 20mm
60mm + 20mm + 20mm + 10mm + 20mm + 10mm + 20mm + 20mm
180 mm

What is the sum of the series E3n?
The solution is Option D.
The sum of the arithmetic sequence is 5,490
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the sum of the arithmetic progression be represented as S
Now , the number of terms n = 60
Let the first term be a₁ = 3n , when n = 1
a₁ = 3
Now , the second term a₂ = 3n , when n = 2
a₂ = 6
So , the common difference of the arithmetic sequence d = second term - first term
d = 6 - 3
d = 3
Now , the sum of the first n terms of the sequence is
Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Substituting the values in the equation , we get
S₆₀ = ( 60/2 ) [ 2 ( 3 ) + ( 60 - 1 ) ( 3 ) ]
On simplifying the equation , we get
S₆₀ = 30 [ 6 + 59 ( 3 ) ]
S₆₀ = 30 [ 6 + 177 ]
S₆₀ = 30 ( 183 )
S₆₀ = 5490
Therefore , the value of S is 5,490
Hence , the sum of the arithmetic sequence is 5,490

A shipping box is in the shape of a rectangular prism. It has a volume of 9,000 in.3, and the dimensions of the base are 20 in. by 30 in. What is the height of the box?
15 in.
20 in.
300 in.
600 in.
ITS NOT 20 I TOOK THE TEST AND GOT IT WRONG
Answer:
15 in.
Step-by-step explanation:
Volume of rectangular prism = length × width × height
Length = 30 in
Width = 20 in
Height = x
Volume of rectangular prism = 9000 in³
Volume of rectangular prism = length × width × height
9000 = 30 × 20 × x
9000 = 600x
x = 9000/600
x = 15 in
Answer:
15
Step-by-step explanation:
the formula of finding the volume of a rectangular prism is base times height. the base dimensions are 20*30 so its 600 square inches, 9000/600=15.
Ray is late for work but would like to drink some coffee before he leaves. The coffee in the pot is too hot, so Ray puts 20 small ice cubes in a mug before pouring in the coffee. The ice cubes measure 1 cm per side. The mug is cylindrical and has a height of 9 cm and a base of 7 cm. What is the volume of the coffee that will fill the mug after the ice cubes have been added (round to the nearest whole number)?
A) 113 cm3.
B) 326 cm3.
C) 346 cm3.
D) 424 cm3.
Answer:
V,cube = sidelength^3
V,cube = (1 cm)^3
V,cube = 1 cm^3
Since there are 20 ice cubes, V = 20 cm^3
V,cylinder = pi * r^2 * h
V,cylinder = 3.14 * 3.5^2 * 9
V,cylinder = 346.185 cm^3
This is the volume of mug when full.
Since 20 cm^3 is allotted for the ice cube, thus,
346.185 - 20 = 326.185 cm^3
Yes it's B.

Draw a right triangle ABC. AB will represent the ladder, with point A being on the ground and point B being against the building.
Label: AC=6 ft, m<A=73° and <C is a right angle.
Use the trig mnemonic "SOHCAHTOA" to identify that BC/AC=tan<A. So BC, which is the height the ladder reaches, equals AC*tan<A=6*tan(73)=19.6 feet.

C= 7h+125 The Equation above keeps the amount CN dollars an electrician charges for a job it takes eight hours Miss Sanchez and Mr. Online each hired this electrician the electrician worked two hours longer on the Sanchez job then on Mr. Ronald trump how many more did the electrician charge Miss Sanchez than Mr.Roland and
Answer:
$14
Step-by-step explanation:
The total amount, C charged by an electrician for h hours of work is ;
C= 7h+125
If the electrician spends 2 more hours on Sanchez job than Ronald, then the amount Mrs Sanchez paid more than Ronald can be obtained thus:
From the equation :
C= 7h+125
The slope relation with number of hours worked gives the change in amount paid for differebt work hours. Since the intercept is constant, we ignore its value in this exercise.
For 2 more hours of work :
Additional amount = 7h ; h = 2
7h = 7 * 2 = 14
Hence, Mrs Sanchez pays $14 more.
