help me out im stuck on these 2 problems

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]

Answer:

10 3/5

Step-by-step explanation:

7+3=10

1/5+2/5=3/5

Use the Pythagorean theorem!

This principle applies to any right triangles.

This states the relationship between the sides that

(7)² + (24)² = x²

All you have to do is simplify at this point.

49 + 576 = x²

625 = x²

√        √

x = 25

You should try to memorize this right triangle. It can be very helpful in fast questionnaires, such as the SAT.

Answer:960

Step-by-step explanation:

Answer:

25 boxes

Step-by-step explanation:

1)  Volume of each box = edge * edge * edge

                                        = 2.5 * 2.5 * 2.5

                                        = 15.625 cubic feet

Find the volume of the cargo hold and the volume of one box.

When you load one box, the space of the cargo hold will reduce. So when you add more boxes, the space of cargo hold will reduce continuously. So continuous subtraction is divsion.

To find the number of boxes, divide the volume of cargo hold by the volume of each box.

Number of boxes = Volume of cargo hold÷ volume of one box

                             [tex]= \frac{length *width * height}{edge * edge*edge}\\\\= \frac{15*7.5*7.5}{2.5*2.5*2.5}\\\\= 54[/tex]

Answer:

B

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.

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 ;

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.

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.

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
