The diameter of Jupiter at its equator is approximately 1.43 x 10 to the 5th power kilometers. Write this number in standard notation. An astronomer's infrared telescope is able to detect radiation with a wavelength of 0.000439 meters. Write this number in scientific notation.
The number in standard notation is 143,000.
The number in scientific notation is 4.39 x 10^-4
What is scientific and standard notation?
Scientific notation is used to compress large numbers into smaller numbers. In order to write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
For example:
• The number : 1 x 10² is equivalent to 100
• The number 5 x 10³ is equivalent to 500
When changing a number that is less than 1 to scientific notation, there would be a negative sign before the power.
0.000439 = 4.39 x 10^-4
In order to convert a number from scientific notation to standard notation, multiply the number by its power.
1.43 x 10^5
= 1.43 x 100,000 = 143,000

On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload. If he orders 2000 and Briggs will he have enough to complete a job require a 1900 bricks?
Yes, Briggs will have enough to complete a job requiring 1900 bricks. Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.
Given that On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload.
He orders 2000.
We need to see whether Briggs will have enough to complete a job requiring 1900 bricks.
How to find a percentage of a number?Example:
- 20% of M
= 20/100 x M
= 1/5 x M
- 25% of M
= 25/100 x M
= 1/4 x M
Find 4.5% of 2000.
= 4.5% x 2000
= 4.5 / 100 x 2000
= 4.5 x 20
= 45 x 2
= 90
The remaining bricks are:
= 2000 - 90
= 1910
We see that Briggs will have enough to complete a job requiring 1900 bricks.
1910 > 1900.
Thus, Briggs will have enough to complete a job requiring 1900 bricks.
Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.

Sasha has 520cm of rope she uses 2m 72mm of the rope how many millimeters of rope does Sasha have left?
Accoding to the given statements;
Sasha have left 2480 mm of rope.
According to the given values;
Sasha has 520 cm of rope
She used 2m 72 mm of rope
So, 1 cm = 10mm
And 1m = 1000mm
So, 520 × 10 = 5200mm
2.72× 1000 = 2720mm
5200 - 2720 = 2480mm

the second machine makes a part every 45 seconds. The quality control engineer
tests these parts each time they both come out of the machines at the same time.
How often does she test the parts? Show your work and express your answer

Using the least common factor, it is found that she tests the parts once every 3 minutes.
How to find the time it takes for periodic events to repeat at the same time?To find the time that passes between the events happening at the same time, we need to find the least common multiple of the periods.
For this problem, the periods are of 12 seconds and 45 seconds. The least common factor is found factoring both terms by prime factors, as follows:
12 - 45|2
6 - 45|2
3 - 45|3

b) The manager turns on the restaurant's two neon signs at the same time. Both signs blink as they are turned o. One blinks every 9 seconds. The other sign blinks every 15 seconds. In how many seconds will they blink together again?
The possible answers for the restaurants are Three 8-hour shifts; four 6-hour shifts; six 4-hour shifts.
2. The seconds that they will blink together again is 45 seconds.
How to illustrate the information?Here we have to determine the factors of 24 for the shifts i.e. 1, 2, 3, 4, 6, 8, 12, 24 .
A 1-hour shift does not make much sense; most employers will also not use a 2-hour or 3-hour shift.
Restaurants typically do not use 12-hour shifts either, and employers do not use 24-hour shifts either.
Since both signs blink as they are turned on and one blinks every 9 seconds. The other sign blinks every 15 seconds. The least common multiple is 45.

∠ABC + ∠BCA + ∠CAB = 180
therefore, ∠ABC = 180 - ∠BCA - ∠CAB
using this formula to solve 4a, 4b and 4c:
4a. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 49 -57 = 26
∠ABC = 26
4b. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 28 -90 = 62
∠ABC = 62
4c. ∠ABC = 180 - ∠BCA - ∠CAB = 180 - 38 - 25 = 117
∠ABC = 117
5a. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180
∠BCA = 180 - ∠CAB - ∠ABC = 180 - 55 - 60 = 65
∠BCA = 65
∠BCD + ∠BCA = 180
therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 65 = 115
∠BCD =115
5b. In the Triangle ABC, ∠BCA + ∠CAB + ∠ABC = 180
∠BCA = 180 - ∠CAB - ∠ABC = 180 - 125 - 30 = 25
∠BCA = 25
∠BCD + ∠BCA = 180
therefore substituting for ∠BCA in, ∠BCD = 180 - ∠BCA = 180 - 25 = 155
∠BCD = 155
5c. ∠ABD + ∠CBD = 180
therefore ∠CBD = 180 - ∠ABD = 180 - 132 = 48
∠CBD = 48
In the Triangle BCD, ∠CBD + ∠BDC + ∠BCD = 180
therefore ∠BCD = 180 - ∠CBD - ∠BDC = 180 - 48 - 71 = 61
∠BCD =61

Jaspar deposits £2,500 into a savings account at 7% per annum compound interest.
How much does he have in his account after 2 years?
Jasper had 362.25 in his account after two years, per the given statement.
What exactly is compound interest?The interest you earn upon interest is known as compound interest. This may be demonstrated with simple math: if you have $100 and that it earns 5% interest every year, you will have $105 at the end of the first year. You'll have $110.25 by the end of the second year.
According to the given data:Given:
Jaspar deposits £2,500
interest rate = 7
Time = 2 year
Compound interest is interest calculated on the aggregate amount rather than the principle amount alone.
Amount = P(1+r/100)^n
=2500(1+7/100)²
=2500(100+7/100)²
= 2500(107/100)²
= 2862.25
C.I.= Amount - Principal

The value of x is 6
What is a line segment?A line segment can be defined as the partition formed by end points of a line.
From the information given, we have that line JL is the line with segments JK, KL and JL and K and the midpoint between J and L
This can be represented as;
JK + KL = JL
Where;
JK = 5x-8KL = 7x-12JL = 52Substitute the values into the formula, we have;
5x -8 + 7x - 12 = 52
Now, collect like terms
12x = 52 + 20
