Answer:
10 3/5
Step-by-step explanation:
Convert mixed fraction to improper fraction.
[tex]7\frac{1}{5}=\frac{(7*5)+1}{5}=\frac{35+1}{5}=\frac{36}{5}\\\\3\frac{2}{5}=\frac{17}{5}\\[/tex]
Now add
[tex]7\frac{1}{5}+3\frac{2}{5}=\frac{36}{5}+\frac{17}{5}\\\\=\frac{36+17}{5}\\\\=\frac{53}{5}\\\\= 10\frac{3}{5}[/tex]

A sequence can be generated by using an = 4a(n - 1), where a1 = 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
A: 6, 24, 96, 384
B: 6, 10, 14, 18
C: 6, 20, 100, 500
D: 6, 20, 76 300
Answer:
First four terms are: 6 , 24 , 96 , 384
Step-by-step explanation:
a₁ = 6
an = 4a(n-1)
a₂ = 4* a₍₂₋₁₎ = 4 * a₁ = 4*6 = 24
a₃ = 4*a₍₃₋₁₎ = 4 * a₂ = 4 * 24 = 96
a₄ = 4* a₍₄₋₁₎ = 4 * a₃ = 4 * 96 = 384
You randomly choose one of the four marbles. Without replacing the first marble, you choose a second marble. there are 1 blue, 1 green, 1 yellow, and 1 red. Use tree diagram
Answer:
12 total possible outcomes
Step-by-step explanation:
To do this, we can use the Fundamental Counting principle, which is :
An event M has m possible outcomes. An event N has n possible outcomes. The total number of outcomes of event N followed by event N is m x n.
When you first pick up a marble (event M), there are 4 possible outcomes (yellow, red, green, blue). Since you do not replace the marble, when you pick the second time (event N) there are only 3 other possible colors.
As we know, m x n = to total possible outcomes.
So, 4 x 3 = 12 total possible outcomes.

What is area?Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.
From the given figure,
Dimensions of a large rectangle, length is 12 ft and breadth is 9 ft.
Area of the large rectangle = Length×Breadth
= 12×9
= 108 square feet
Dimensions of a smaller rectangle, length is 12-7=5t ft and breadth is 13-9=4 ft.
Area of the smaller rectangle = Length×Breadth
= 5×4
= 20 square feet
Total area = 108+20
= 128 square feet
Therefore, the number of square feet of carpet Sara needs is 128 square feet.

Select all the figures with a 180-degree rotation symmetry.
The figures with a 180° rotation symmetry is B C and E.
The figures having 180 degree rotation symmetry are figure B , figure C and figure E.
Some figures are given in the question.
We have to find out which of the given figures have 180 degree rotation symmetry.
What do you mean by rotational symmetry ?
Rotational symmetry is defined as the property a shape has when it looks the same after some no. of rotations.
As per the question ;
We have to check which of given figures have rotational symmetry.
We know that ;
For a shape to have a rotational symmetry, the following must be true ;
The shape must have an even number of sides i.e., 4 , 6 , etc.The shape must have equal and parallel opposite sides.If we check according to the above conditions ;
Figures (A) and (D) don't meet the conditions.
However, the above conditions are true for figures (B), (C) and (E).
This is because a rectangle , a square and a regular hexagon has equal & parallel opposite sides; and also even number of sides.
Thus , the figures having 180 degree rotation symmetry are figure B , figure C and figure E.

The ages of Beau's cousins are represented by the box plot
Which statement is supported by the data in the box plot?
Find the volume of the following figure. 890 units 3 900 units 910 units 3 882 units3
Answer: 882 units cubed
Step-by-step explanation:
The following shape is a cuboid, which means we need to multiply the length by height by width.
The units we are using are cubes.
To calculate the 3 dimensions, we need to manually count the cubes.
Length = 14 units
Height = 9 units
Width = 7 units
Volume = Length * Height * Width
V = 14 * 9 * 7
V = 882 units cubed.
Which means, in that big box could fit 882 little cubes as shown.
