The red-shaded part represents the fraction 2/7.
We are given an image of circle in the question which has 7 equal parts with two parts shaded red and the other five shaded white.
We have to find the fraction that represents the red shaded part of the circle.
A fraction defined as the part of the whole thing. For example, a pizza is divided into 6 equal pieces, then each piece is represented by 1/6.
We know that,
Fraction of red shaded part = Number of red parts/ Total number of parts
Here,
Number of red parts = 2
Total number of parts = 7
Hence,
Fraction of red shaded part = 2/7

Which formula can be used to describe the sequence?
-2/3, -4, -24, -144,...
The formula that describes the sequence given i.e. [tex]\frac{-2}{3}[/tex],-4,-24,-144 (geometric sequence) is [tex](\frac{-2}{3} )(6)^{n-1}[/tex]
Geometric progression:
A geometric progression or a geometric sequence is a series, in which each word is varied by another by a common ratio. When we multiply the previous term by a constant (which is non-zero), we get the following term in the sequence. It is symbolized by:
A, AR,[tex]AR^{2}[/tex],[tex]AR^{3}[/tex]...
Where A is the first term of the geometric sequence and R is the common ratio of the geometric sequence.
The general term of geometric sequence i.e. nth term =[tex]AR^{n-1}[/tex]
Given that A= [tex]\frac{-2}{3}[/tex] and R=6
As a result the general term of geometric sequence i.e. nth term =[tex](\frac{-2}{3} )(6)^{n-1}[/tex]
Therefore,The formula that describes the geometric sequence given i.e. [tex]\frac{-2}{3}[/tex],-4,-24,-144 is [tex](\frac{-2}{3} )(6)^{n-1}[/tex]

Imagine that we paint a 4 x 4 x 4 cube blue on every side.
How many of the small cubes have 3 blue faces?
How many have 2 blue faces?
How many have 1 blue face?
How many faces would be painted in a cube of any size?
How many have not been painted at all?
If we paint a 4 x 4 x 4 cube blue on every side then we will get 8 small cubes having 3 blue faces, 16 cubes having 2 blue faces, 24 cubes with 1 blue face, 6 faces would be painted in a cube of any size and 8 cubes have not been painted at all.
Elaborate the answer that is obtained above.Corner cubes are the only ones with 3 faces, whereas a cube has 8 corners. There are therefore 8 cubes with 3 blue faces.
Each of the 16 cubes has 2 blue faces. These are the cubes found between the sides' corners.
The 4 center cubes have only 1 side painted. Because each side has six sides and four center cubes, 6 x 4 = 24. As a result, 24 cubes have 1 blue face.
Because a cube has 6 faces, every size cube will have at least 6 colored faces.
On the inside of the larger cube, there are exactly 8 cubes. As a result, 8 cubes have been left unpainted.

Find the difference: 20-√80
O-12√5
O-2√5
02√5
O-2√15
Step-by-step explanation:
maybe you missed something in the problem definition or in the answer options, but the answer options do not contain any right answer to the described problem.
20 - sqrt(80) = 20 - sqrt(16×5) = 20 - 4×sqrt(5) =
= 11.05572809...
it is simple to estimate, in what dimension the result should be : 80 is very close to 81. so the sqrt(80) is also very close to the sqrt(81), which is 9.
20 - 9 = 11.
so, all the negative answer options are wrong by default.
and the only positive one is 2×sqrt(5) = 4.472135955...
additional thoughts :
20 = 4×5 or 4×sqrt(5)×sqrt(5)
so, we could write the problem as
4×sqrt(5)×sqrt(5) - 4×sqrt(5)
which could be simplified to either
4×sqrt(5)×(sqrt(5) - 1)
or
4×(5 - sqrt(5))

Almost a billion people on the planet don’t have access to clean drinking water.” If there are 6.9 x 109 people in the world, then approximately what percent of them live without clean drinking water? Round to the nearest tenth of a percent.
The percent of them that live without clean drinking water is; 14.5%
How to find the percentage?
We know from scientific notation that;
1 billion = 1 * 10⁹
Now, we are told that there are 6.9 * 10⁹ people in the world. Thus, if almost a billion people on the planet don't have access to clean drinking water, then the percent of them that live without clean drinking water is;
(1 * 10⁹)/(6.9 * 10⁹) * 100%

A pair of shoes is regularly priced at $80 and is on sale for 20% off. You have a coupon to receive an additional 15% off the sale price. How much will you pay for the shoes?
The customer would pay $54.40 for the shoes
What is the dollar value of the initial discount of 20%?
The dollar worth of the general discount of 20% of the price of $80 is determined as 20% multiplied by the shoe price
dollar worth of initial discount=20%*$80
dollar worth of the initial discount=$16
the price after the initial discount=$80-$16
the price after the initial discount=$64
The fact the customer has a coupon to receive additional 15% off the sale price means the purchase price for the customer is as computed thus:
final sale price=$64*(1-15%)

PROBABILITY!!! Hospitals typically require backup generators to provide electricity in the event of a power outage. Assume that emergency backup generators fail 35% of the times when they are needed. A hospital has two backup generators so that power is available if one of them fails during a power outage. Complete parts (a) and (b) below.
A) In the event of a power loss, the possibility of both generators failing is 0.1225.
B) (i) In the case of a power outage, having a functioning generator may be anticipated 87.75% of the time.
(ii) During a power outage, it may be anticipated that both generators will malfunction roughly 12.25% of the time.
Probability: The probability of an occurrence is defined as the ratio between the number of positive outcomes to a certain event and the entire number of potential outcomes.
Complementary Events: When event A is specified, the complement of that event A does not take place.
Union of two events: The term "union of two events" refers to the collection of outcomes that are either related to both occurrences or one of the two events.
The intersection of two events: The intersection of two events refers to the group of results that are related to both occurrences.
Independent Events: If the occurrence of one event does not influence the occurrence of another event, then two occurrences A and B are said to be independent events. To put it another way, if the occurrence of event A has no bearing on the occurrence of event B, then the two occurrences A and B are independent.
A) The likelihood that both generators would malfunction during a power outage is calculated as follows:
According to the data provided, emergency backup generators malfunction 35% of the time when they are required. The probability value is 0.35 in this case.
The required probability is,
P⎝|⎛Bothgeneratorsfailduringapoweroutage⎠|⎞
= ⎣⎡P(Firstgeneratorfail) × P(Secondgeneratorfail)⎦ |⎤
= 0.35 × 0.35 = 0.1225
When there is a power outage, the likelihood that both generators will fail is calculated by multiplying the likelihood that the first and second generators will fail. During a power outage, the failure of both generators may be anticipated roughly 12.25% of the time.
B) (i) The likelihood of having a functional generator during a power outage is calculated as indicated below:
The required probability is,
P⎝|⎛Workinggeneratorintheeventofapoweroutage⎠|⎞
= 1−P⎝|⎛Bothgeneratorsfailduringapoweroutage⎠|⎞ =
1−0.1225 = 0.8775
The likelihood that a generator will operate in the case of a power loss is calculated by deducting the likelihood that both generators would malfunction from the overall likelihood. In the case of a power outage, having a functioning generator may be anticipated 87.75% of the time.
(ii) The likelihood that a patient will require hospitalization or not is determined as follows:
When there is a power outage, there is a 12.25% chance that both generators will malfunction; this means that they will malfunction roughly 10% of the time.
It is obvious that it is possible to anticipate that during a power outage, both generators will fail roughly 12.25% of the time, suggesting that this probability is low enough to not have an effect on patients' health.

The value of 400 when it is divided by 10 will be 40.
Division is the one of the four fundamental arithmetic operations. The other operations include multiplication, addition, and subtraction.
It is denoted by " ÷ " sign
For example: 4 ÷ 2 = 2, 18 ÷ 6 = 3, 50 ÷ 1 = 50, 40 ÷ 4 = 10, 66 ÷ 3 = 22, 999 ÷ 9 = 111 or 90 ÷ 3 = 30
The division will be calculated as below:-
We will divide 400 by 10 to obtain the required value.
Division = 400 ÷ 10
Division = 40
Therefore, the value of 400 when it is divided by 10 will be 40.
