Over 5 days, Kimberly sheared 300 sheep. How many would she be able to shear in 26 days?
What was her rate per day?
Answer:
Kim shears 1560 sheep in 26 days.
Her rate per day is 60.
Step-by-step explanation:
For 26 days:
[tex]\frac{5}{300} =\frac{26}{x} \\\\5x=7800\\x=1560[/tex]
For per day:
[tex]\frac{5}{300} =\frac{1}{x} \\\\5x=300\\x=60[/tex]

The diameter of a bacteria species A is 1 micrometre long while bacteria B is 1 x 10^-3 the size of bacteria species A.
a) What is the diameter of bacteria species B in metres?
b) Based on your answer in (a), is the value obtained less than, greater than or equal to 1 nanometre?
Answer:
Bacteria A has diameter size of 1 micrometer = 1 × 10⁻⁶ m
a) B is 1× 10⁻³ size of A:
1 × 10⁻⁶ * 1 × 10⁻³ = 1 × 10⁻⁹ mb) 1 nanometer = 1 × 10⁻⁹ m
And bacteria B diameter size is equal to 1 nanometerequivalent fractions for 2 1/5 and 1 5/6
Will mark branliest. What can the maximum number of digits be in the repeating block of digits in the decimal expansion of 1/17?
Answer:
Step-by-step explanation:
Let n=2α⋅5β⋅m , where gcd(m,10)=1 . Then, the decimal expansion of 1n is of the form
0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,
where k=max{α,β} and ℓ is the least positive integer for which m∣(10ℓ−1) . In other words, ℓ is the order of 10 in the multiplicative group of units modulo m . So ℓ∣ϕ(m) by Lagrange's theorem.
In particular, if gcd(n,10)=1 , then α=β=k=0 , m=n , and
1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)
Therefore, we know that
117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)
Here ℓ is the least positive integer for which 17 divides 9…9ℓtimes , and we know that ℓ divides ϕ(17)=16 .
Successively squaring 10 modulo 17 gives
102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .
So ℓ=16 in expansion (3) .
In fact,
a1…a16×17=1016–1.
a1…a8+a9…a16=108−1 .
The first fact has nothing to do with the denominator n being prime. The second fact has everything to do with n being prime, and was discovered by E. Midy in 1836 .

Latasha explores some passages in a cave. The elevations of the passages are all above - 10 meters. Let y be the elevation of a passage in meters. Write an inequality that represents elevations above -10 meters.
Answer:
It is y>-10
Step-by-step explanation:
i did it and i got it right.
The inequality that represents elevations above -10 meters is y > -10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.
This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.
If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.
Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.
Thus,
The inequality that represents elevations above -10 meters is y > -10.

Step-by-step explanation:
Using the exponential growth function for the U. S. population from 1970 through 2003:
A = 205.1e^0.011t
with the U.S. population being 205.1 million in 1970, when would the U. S. population reach 350 million?
A.
2028
B.
2048
C.

D.

We have the expression
A = 205.1e^0.011t
We are asked to find when would the U. S. population reach 350 million
A = 350
350 = 205.1e^0.011t
We divide both sides by 205.1
Divide both sides by 205.1
350/205.1 = 205.1e^0.011t/205.1
1.7064846416 = e^0.011t
We take the log of both sides
log 1.7064846416 = log e^0.011t
log 1.7064846416 = t log 0.011
t = log 1.7064846416/ log 0.011
t = 0.1185057826

If a letter is randomly chosen, what is the probability of choosing the letter A?
Answer:
it depends on how many letters there are to choose from.
Answer:
if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%
Step-by-step explanation:
There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!
Or if you want to be really specific, 1/26 as a percent is 3.8462%.
Cuboid ABCDEFGH is shown

Find the size of the angle between CF and the Plane ABCD
NEEDS ASAP WILL MARK AS BRAINLIEST IF CORRECT
Answer:
The angle formed between CF and the plane ABCD is approximately 47.14°
Step-by-step explanation:
The given parameters are;
BC = 6.8
DE = 9.3
∠BAC = 52°
We note that the angles formed by the vertex of a cuboid are right triangles, therefore, by trigonometric ratios, we get;
sin∠BAC = BC/(The length of a line drawn from A to C)
∴ The length of the line drawn from A to C = BC/sin∠BAC
The length of the line drawn from A to C = 6.8/sin(52°) ≈ 8.63
∴ AC = 8.63
By trigonometry, we have;
The angle formed between CF and the plane ABCD = Angle ∠ACF
[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent\ leg \ length}[/tex]
[tex]tan\angle ACF = \dfrac{FA}{AC}[/tex]
In a cuboid, FA = BG = CH = DE = 9.3
[tex]\therefore tan\angle ACF = \dfrac{9.3}{8.63}[/tex]
[tex]\therefore \angle ACF = arctan \left(\dfrac{9.3}{8.63} \right) \approx 47.14^{\circ}[/tex]
The angle formed between CF and the plane ABCD = Angle ∠ACF ≈ 47.14°

Answer:
Step-by-step explanation:
Note how this drawing is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.
Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30. Due to the symmetry shown, line CD has the same length: 30.
