Answer:
147.2 × 10 raised to the 6th power.
Step-by-step explanation:
First you have to convert them normal numbers. The first one is 46,000. The second one is 3,200. The four and three help to indicate the number of zeros behind that 1. 4.6 times 10000 would be 46000. (move the decimal to the right).
Then after multiplying the numbers you have to convert them back to scientific notation. Write the number out, 147,200,000. Then slice the decimal right in between 7 and 2 to form a decimal with only a tenths place. Count how many places there are to the end, and that will be the exponent you will use.
To check answer convert to number.
Answer:
42800
Step-by-step explanation:
First do the exponent in the first parenthesis which would get you 10000 then multiply with 4.6. Now you have 46000-(3.2· 10³)
then do the exponent in it. Now you have 3.2·1000= 3200
So now your final equation is 46000-3200
42800

A 30 foot ladder is set against the side of a house so that it reaches up 24 feet. If Alexander grabs the ladder at its base and pulls it 10 feet farther from the house, how far up the side of the house will the ladder reach now? (The answer is not 14 ft.) Round to the nearest tenth of a foot.
Answers
Answer:
The answer would be 10.8
Step-by-step explanation:
By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).
Hope this helps :)
The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
The ladder is making a right-angle triangle with a wall as shown below.
By Pythagoras's theorem,
x² = 30² - 24²
x = 18
By Pythagoras's theorem,
y² = 30² - (18 + 10)²
y = 10.77 feet
Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".

If a die cast rally car drove 81 meters per second, how long did it take for it to go 90 meters. Round your answer to the nearest HUNDREDTH.
Answers
Answer:
The car took 1.11 seconds to go 90 meters.
Step-by-step explanation:
Set up an equation:
Variable x = number of seconds to travel 90 meters
81 meters/1 second = 90 meters/x seconds
Take out the variables for now to focus on calculations:
81/1 = 90/x
Cross multiply:
81 × x = 1 × 90
81x = 90
Divide both sides by 81:
x = 1.111111111... seconds
Round to nearest hundredth (hundredth is the second decimal place):
x = 1.11

What is the distance between points on a line parallel to X-axis?
"The distance between points [tex](x_1,y_1),(x_2,y_2)[/tex] on a line parallel to X-axis is, [tex]d=|x_2-x_1|[/tex] "
For given question,
From the graph of ΔABC,
The co-ordinates of A = (1, 2)
The co-ordinates of B = (6, 2)
For ΔABC, the side AB is parallel to X-axis.
Let [tex](x_1,y_1)=(1,2),(x_2,y_2)=(6,2)[/tex]
Using the formula for the distance between points on a line parallel to X-axis,
[tex]\Rightarrow d=|x_2-x_1|\\\\\Rightarrow d=|6-1|\\\\\Rightarrow d=|5|\\\\\Rightarrow d=5~units[/tex]
Therefore, the length of AB = 5 units

Help it’s (Graphing Lines in Slope-Intercept Form) 7th grade work
Answers
Answer:
y=mx+b
Step-by-step explanation:
to find the slope, pick two points (easiest if its an even point without decimals). the equation to find slope is m= y2-y1/x2-x1. Once you plug those in, from the two points, you should get a fraction or whole number--depends if it's simplifiable or not. Then plug that in to point slope form: y-y1= m (<the slope) (x-x1). The negatives by y1 and x1 in this equation make the number either negative or positive--if the number is negative it turns positive, and if it's positive it turns negative. Once you plug in those values, you should distribute the slope to the parentheses and combine like terms.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Jeremy uses 27 inches of the board for each birdhouse to build.
so, by the proportion
To Calculate how many inches of the board he need to make 6 birdhouses.
27/ 1 = x / 6
x = 6 * 27
x = 162 in
To convert inches to yards
1 yd = 36 in
1 in = 1/ 36 yd
162 in = 162 * 1/ 36 yd
= 4.5 yd
