Answer:

Step-by-step explanation:
Make 4 [tex]\frac{2}{5}[/tex] an improper fraction. To do that multiply the denominator, 5 by 4, which gets you 20. Then add the numerator, 2, to get 22. put the original denominator back into the fraction, and you get [tex]\frac{22}{5}[/tex] . If you divide that by [tex]\frac{2}{5}[/tex] , you would get 11 because you divide the numerator and the denominators cancel each other out since they are both the same number, and 22 ÷ 2 = 11.

how many times can 38 go into 192 using long division
Answer: 5.0526
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 38 on the left side and the dividend 192 on the right side like this:
3 8 ⟌ 1 9 2
Step 2:
The divisor (38) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
3 8 ⟌ 1 9 2
Step 3:
Multiply the divisor by the result in the previous step (38 x 0 = 0) and write that answer below the dividend.
0
3 8 ⟌ 1 9 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
3 8 ⟌ 1 9 2
- 0
1
Step 5:
Move down the 2nd digit of the dividend (9) like this:
0
3 8 ⟌ 1 9 2
- 0
1 9
Step 6:
The divisor (38) goes into the bottom number (19), 0 time(s). Therefore, put 0 on top:
0 0
3 8 ⟌ 1 9 2
- 0
1 9
Step 7:
Multiply the divisor by the result in the previous step (38 x 0 = 0) and write that answer at the bottom:
0 0
3 8 ⟌ 1 9 2
- 0
1 9
0
Step 8:
Subtract the result in the previous step from the number written above it. (19 - 0 = 19) and write the answer at the bottom.
0 0
3 8 ⟌ 1 9 2
- 0
1 9
- 0
1 9
Step 9:
Move down the last digit of the dividend (2) like this:
0 0
3 8 ⟌ 1 9 2
- 0
1 9
- 0
1 9 2
Step 10:
The divisor (38) goes into the bottom number (192), 5 time(s). Therefore put 5 on top:
0 0 5
3 8 ⟌ 1 9 2
- 0
1 9
- 0
1 9 2
Step 11:
Multiply the divisor by the result in the previous step (38 x 5 = 190) and write the answer at the bottom:
0 0 5
3 8 ⟌ 1 9 2
- 0
1 9
- 0
1 9 2
1 9 0
Step 12:
Subtract the result in the previous step from the number written above it. (192 - 190 = 2) and write the answer at the bottom.
0 0 5
3 8 ⟌ 1 9 2
- 0
1 9
- 0
1 9 2
- 1 9 0
2
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 192 divided by 38 calculated using Long Division is: 5.0526

An ice cream store sells 26 flavors of ice cream, determine the number of 6 dip sundaes. how many are possible if order is not considered and no flavor is repeated?

The number of possible orders is 2,30,230.
What is combination?Combinations are ways to choose things from a collection where the order of the choices is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.
The definition of the combination is "An arrangement of objects where the order of the objects is irrelevant." Combining the words indicates "Selection of things," where the order of the items is irrelevant.
Given total numbers of flavours = 26
number of dip = 6
Combinations allows us to create various sets of x components from a total of n elements, where their order is irrelevant and no member is repeated.
Combinations can be mathematically stated as:
ⁿCₓ = [tex]\frac{n!}{(n - x)!x!}[/tex]
we have n = 26
and x = 6
ⁿCₓ = [tex]\frac{n!}{(n - x)!x!}[/tex]
²⁶C₆ = [tex]\frac{26!}{(26 - 6)!6!}[/tex]
26! = 26 x 25 x 24 x 23 x 22 x........ x 1
6! = 6 x 5 x 4 x 3 x 2 x 1
²⁶C₆ = 26!/(20!6!)
²⁶C₆ = 26 x 25 x 24 x 23 x 22 x 21 x 20!/(20!6!)
²⁶C₆ = 26 x 25 x 24 x 23 x 22 x 21/(720)
²⁶C₆ = 2,30,230
Hence the numbers of orders are 2,30,230.

An electrician charges $50 for the first hour and $5.50 for each additional hour write an equation to represent the amount the electrician will earn when h represents the number of hours worked and t represents the total amount earned( in dollars)
the equation would be t=5.50(h)+50
Find the value of p in the equation, 0.25p-50=240
Answer:
p = 1160
Step-by-step explanation:
0.25p-50=240
0.25p = 240+50 (Transfer the 50 and isolate the p)
[tex]\frac{1}{4}[/tex]p = 290 (Changing the decimal to a fraction so it is easier to see)
[tex]\frac{4}{4}[/tex]p = 4×290 ([tex]\frac{1}{4}[/tex]×4 = [tex]\frac{4}{4}[/tex])
p = 1160
Answer:
p=1160
Step-by-step explanation:
Its's easy. If there ever is any number with a letter in the equation, you are most likely to divide that number. First, since 50 has a minus in front of it, you have to add that to the 50 in the equation AND the 240. When you do 50 plus the 50 in the equation it cancels out because -50+50 is 0 (you don't add the 0 to the equation because you are looking for p.) So, 240+50 is 290. Now, you have to divide 0.25 to the 0.25p AND the 290. 0.25 divided by 0.25p is 1, BUT you never put 1p you just put p because p is the same as 1. 290 divided by 0.25 is 1160. So your equation should look like p=1160

Partial products of 16 x 34
Answer:
544
Step-by-step explanation:
trust me math is easyyy
The required partial product is given as 340 + 204 = 544.
Given that,
To determine the partial product of the 16 × 34.
In mathematics, partial products are defined as multiplying each digit of one integer by each digit of another number while keeping each digit's place value.
here,
According to the question,
16 × 34 = [10 + 6] × 34
= [10 × 34 + 6 × 34]
= [340 + 204]
= 544

Maria is framing an 8 inch by 10 inch photograph with matting as shown. Which is an expression for the area of the photograph with the mat?
Answer:
[tex] 4x^2 + 36x + 80 [/tex]
Step-by-step explanation:
Area of the photograph with the mat = area of the photograph + area of the mat
Area of the photograph = length * width = 10*8 = 80 in²
Area of the mat:
Decompose the mat frame into 4 rectangles and 4 squares (these are the corners of x*x dimensions)
The 4 rectangles = 2(8*x) + 2(10*x) = 16x + 20x = 36x
The 4 squares (the corners) = 4(x*x) = 4x²
The area of the photograph with the mat = 80 + 36x + 4x²
Rearrange in standard form:
The expression for the area would be:
✅[tex] 4x^2 + 36x + 80 [/tex]
