HELP PLEASE !!!!!!!Estimate each number as a single digit times a power of ten.drag expressions to complete the table each expression may be used or not at all
Answer:
1 is 4x10^-9
2 is 4x10^10
3 is 5x10^7
4 is 2x10^-5
Step-by-step explanation:
I also would use calculator soup it's a good website
The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
Therefore, each number as a single digit times a power of ten.
1. 0.000000043 is [tex]4 \times 10^{-9}[/tex]
2. 43560000.000 is[tex]4 \times 10^{10}[/tex]
3. 56.234567 is [tex]5 \times 10^7[/tex]
4. 0.00002346 is [tex]2 \times 10^{-5}[/tex]
Hence, The numbers as a single digit times a power of ten are ; 1. 4x10^-9, 2. 4x10^10, 3. 5x10^7, 4. 2x10^-5

Mhanifa please help me on this it’s really difficult. I will mark brainliest! Point P is the centroid of triangle ABC. Use the given information to find the indicated measures.
Answer:
The centroid of a triangle is the intersection of the three medians of the triangle. The centroid theorem states that the centroid of the triangle is at 2/3 of the distance from the vertex to the mid-point of the sides.As per above mentioned property, we have:
Question1
AL = 27 - given AP = 2/3 AL = 2/3(27) = 18 PL = 1/3 AL = 1/3(27) = 9Question 2
BP = 102 - given BP = 2/3 BL ⇒ BL = 3/2(CP) = 3/2(102) = 153 PL = 1/3 BL = 1/3(153) = 51Please help me

Answer:
50,000 joulesStep-by-step explanation:
total mass of people = 50× 5 = 250kg
height = 20m
force = mass × g = 250× 10 ( taking g= 10m/s²)
f= 2500Nwork done = force × distance
= 2500× 20

The mass of 25 packets of biscuits is 0.7kg. There are 4 biscuits in 1 packet. What mass of 1 biscuit?
Answer:
0.007 kg
Step-by-step explanation:
There are 25 packets
Each packet contains 4 biscuits.
The total number of biscuits = 4 * 25
The total number of biscuits = 100
100 biscuits = 0.7 kg
1 biscuit is 0.7 kg / 100
1 biscuit is 0.007 kg
If you are not sure of this, put it in a calculator.
Just out of curiosity note that 1 kg = 1000 grams
0.007 kg = 0.007 * 1000 = 7 grams each.
use 0.007 as your answer.

Paula found a recipe for homemade granola. She decided to make a small batch to start, so she used 1 cup of coconut flakes and 2 cups of oats. It turned out so good, she made a larger batch to bring on her camping trip. For the large batch, she used 3 cups of coconut flakes and 5 cups of oats. Which batch of granola had a stronger coconut flavor?
Answer:
the smaller batch
Step-by-step explanation:
Proportion of coconut in the smaller batch = 2/1 = 2
Proportion of coconut in the bigger batch = 5/3 = 1.67
2 is greater than 1.67. So, the proportion of sugar in the smaller batch is stronger

An alloy consists of 13 parts of copper to 7 parts of zinc and 5 parts of Nickel what is the percentage composition of the alloy
Answer:
52% Copper, 28% Zinc, 20% Nickel
Step-by-step explanation:
Copper is 13 out of 13+7+5 = 25
13/25 = 52%
Zinc is 7 out of 25 so 28%
Nickel is 5/25 = 20%

Find the slope of the line that passes through (8, 5) and (1, 1)
Answer:
Slope: (4/7)
Step-by-step explanation:
Slope formula: y2-y1/x2-x1
5-1=4
8-1=7
4/7= Slope
Answer:
Step-by-step explanation:
(x₁ , y₁) = (8 , 5)
(x₂ , y₂) = (1 , 1)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{1-5}{1-8}\\\\=\frac{-4}{-7}\\\\=\frac{4}{7}[/tex]
Find the error & explain why it is wrong:
Laural had to find the average rate of change of f(x) over the interval from x = 6 to x = 10 using the table below.
What did she do wrong?
Step b is wrong. The slope is the change in y over the change in x.
Step b should be (18- 8)/( 10-6)
= 10/4
= 5/2
