For the sum of (5.2 x 10^4 ) and (6.95 x 10^4 ) in scientific notation, why will the power of 10 be 10^5 ?
Answer:
12.15 *10^4
=1.215 *10^5
it must be like that so as to express it in standard form
The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The numbers in the scientific notation will be given as,
(5.2 × 10⁴) and (6.95 × 10⁴)
Then the sum of the numbers will be
⇒ (5.2 × 10⁴) + (6.95 × 10⁴)
⇒ (5.2 + 6.95) × 10⁴
⇒ 12.15 × 10⁴
The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

6. The sum of the ages of a father and his son is 74. Four years ago the
father's age was twice as old as his son. How old is the father now?
Answer:
A (48)
Step-by-step explanation:
let the father's age = x and his son's age = y
according to the question,
the sum of their ages is 74
×+y=74......equation 1
four years ago (i.e x-4 & y-4) father's age was twice as old as his son
x-4=2(y-4)
or, x-4=2y-8
x-2y=-4.......equation 2
now, in equation 1
x+y=74
hence,
x=74-y
substituting the values in equation 2
x-2y=-4
(74-y)-2y=-4
74-y-2y=-4
74-3y=-4
74+4=3y
3y=78
y=78/3
y=26
Hence the kid is 26 years old
x+y=74
x+26=74
x=74-26
x=48
Hence the dad is 48 years old
Answer:
The correct answer is: Option A: 48
Step-by-step explanation:
Let x be the present age of father and y be the present age of son
Given that
"The sum of the ages of a father and his son is 74"
[tex]x+y = 74\ \ \ Eqn\ 1[/tex]
Now
x-4 will be the age of father 4 years ago
y-4 will be the age of son 4 years ago
The equation will be:
[tex]x-4 = 2(y-4)\\x-4 = 2y-8\\x-2y-4 =-8\\x-2y = -8+4\\x-2y = -4\ \ \ Eqn\ 2[/tex]
From equation 1:
[tex]x = 74-y[/tex]
Putting in equation 2
[tex]74-y-2y = -4\\74-3y = -4\\-3y = -4-74\\-3y = -78\\\frac{-3y}{-3} = \frac{-78}{-3}\\y = 26[/tex]
Put y = 26 in equation 1
[tex]x+26 = 74\\x = 74-26\\x = 48[/tex]
The father is 48 years old now.
Hence,
The correct answer is: Option A: 48

If you have 5000 per 125 mcg and need 7140 how many mcg do you need?
Answer:
178.5mcg
Step-by-step explanation:
If you need 5000 per 125mcg, we can express it as;
5000 = 125mcg
To get the amount of mcg needed for 7140, we will say;
7140 = x mcg
Divide both expression
5000/7140 = 125/x
Cross multiply
5000x x= 7140 * 125
5000x = 892,500
x = 892,500/5000
x = 178.5
Hence the amount og mcg needed is 178.5mcg

What is Addition?Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.
Given there are 40 black balls this is 4 more than twice the number of yellow balls. Therefore, we can write,
Number of black balls = Number of yellow balls + 4
40 = Number of yellow balls + 4
Number of yellow balls = 36
Hence, the number of yellow balls is 36.

The mural of your school mascot is $4$ feet by $12$ feet and is to be completely framed using a single row of square tiles each $2$ inches on an edge. If the tiles are $\$0.10$ each, find the cost, in dollars, of the tiles needed to frame the mural.
Answer:
$19.2
Step-by-step explanation:
The school mascot is rectangular in nature.
Perimeter P = 2(L+W)
L is the length = 4feet
W is the width = 12 feet
Perimeter = 2(4+12)
Perimeter = 2(16)
Perimeter = 32 feet
Convert to inches
12in = 1feet
x = 32 feet
Cross multiply
x = 12 * 32
x = 384in
Hence the perimeter of the school mascot is 384in
If it is to be completely framed using a single row of square tiles each 2inches on an edge
2 inches = 1 tiles
384inches = y tiles
Cross multiply
2y = 384
y = 384/2
y = 192 tiles
The number of tiles needed is 192 tiles
Get the cost of 192tiles
If the tiles are $0.10 each. 192 tiles will cost 192 * 0.1 = $19.2
Hence the cost of the tiles needed is $19.2
A bicyclist is riding at a speed of 18 mi/h when she starts down a long hill. The distance d she travels in feet can be modeled by d(t) = 41^2 + 18t, where t is the time
in seconds. How long will it take her to reach the bottom of a 400-foot-long hill?
Answer:
8 seconds
Step-by-step explanation:
d(t)=400
4t^2+18t=400
4t^2+18t-400=0 subtract 400 from both sides
2t^2+9t-200=0 divide by 2 on both sides

The ice cream shop sells sundaes for $2 each and banana splits for $3 each. One day, the shop sold 8 more sundaes than banana splits and also made a total of $156. Which system of equations represents the situation?
Answer:
$82 sundaes
$74 banana split
Step-by-step explanation:
Step one :
Given data
Cost of sundaes =$2 each
Cost of banana split =$3 each
Let the number of sundaes bought be x
And the number of banana split bought be y
The total is x+y
The shop sold 8 more Sundaes than the Banana split
x=8+y—-------1
Total amount made = $156
Therefore the system of equation for the situation is
x=8+y----—----------1
2x+3y=156---------2
But x=8+y
8+y+y=156
8+2y=156
2y=156-8
2y=148
Divide both sides by 2
y=148/2
y=74
On That day they sold $74 banana split
And also they sold x=8+74=$82 sundaes
Zoey has 99 years .She plans to make 5 bangles .Each bangle is made using 30 beads how many more beads does zoey need?
Note: I am assuming you meant to say:
Zoey has 99 beads instead of 99 years.Answer:
Zoey needs 51 more beads to make 5 bangles.
Step-by-step explanation:
Total number of beads Zoey currently has = 99 beads
Beads need to make one bangel = 30 beads
so
Beads need to make 5 bangles = 30 × 5 = 150 beads
Since she has already 99 beads.
So, all we need s to subtract 99 beads from 150 beads.
Therefore,
The number of beads Zoey needs = 150 - 99
= 51 beads
Thus, Zoey needs 51 more beads to make 5 bangles.

Answer:
30
Step-by-step explanation:
The rise is the space between the two points vertically.
We can take the two y points (60 and 120) and find the difference between the two. 120 - 60 = 60 between the two. That means the rise = 60.
The run is the difference between the two points horizontally. We can take the two x points (4 and 2) and find the difference between the two. 4 - 2 = 2. The run = 2. Rise/run = 60/2. This can be simplified to 30/1 or 30.
Eric conducted a survey of the cars in four parking lots and wrote the following observations:
15 of the 36 cars in lot 1 were blue
43 of the 92 cars in lot 2 were blue
12 of the 30 cars in lot 3 were blue
32 of the 52 cars in lot 4 were blue
Based on the survey, which parking lot had the greatest percentage of blue cars?
explain your answer
Answer:
Lot 4 since 61.5% is the highest percentage of blue cars of all lots.
Step-by-step explanation:
Find the percentage that each number of blue cars is in its parking lot.
percent = part/whole * 100%
15 of the 36 cars in lot 1 were blue
15/36 * 100% = 41.667%
43 of the 92 cars in lot 2 were blue
43/92 * 100% = 46.739%
12 of the 30 cars in lot 3 were blue
12/30 * 100% = 40%
32 of the 52 cars in lot 4 were blue
32/52 * 100% = 61.538%
Answer: Lot 4 since 61.5% is the highest percentage of blue cars of all lots.
Answer:
Parking Lot 4
Step-by-step explanation:
15÷36 x 100 = 41.666%
43÷ 92 x 100 = 46.739%
12 ÷ 30 x 100 = 40%
32÷ 52 x 100 = 61%
61% is the largest percentage out of all of them, therefore Parking Lot 4 ( 32 out the 52 cars) is the Parking Lot that has the greatest percentage of blue cars!
