Answer:
Step-by-step explanation:
We know it's a square and that the area is length times width.
So we can square root the given area which is 7sq.m
Therefore the lengths of the sides are 7 m.

Answer:
Yes by AA similarity
Step-by-step explanation:
<ACB is congruent to <ECD by vertical angles, so we have one pair of comgruent angles.
<B is congruent to <CDE because they are both 90 angles, so we have another pair of congruent angles.
Triangle ABC is similar to triangle EDC by AA similarity.

A number minus 14 is more than 35
Answer:
False, -14 is less that 35
Step-by-step explanation:
Answer:
x-14>35
Step-by-step explanation:
x-14>35
1. Replace "A number " with x
x minus 14 is more than 35
Minus = subtraction
x-14 is more than 35
Is more than translates to the inequality >
x-14>35
Hope this helps plz hit the crown :D
There are 64 species of animals in the metropolitan zoo
5/8 are from North America
1/4 are from Africa
The remaining are from South America
How many species are from South America
Answer:
8 species are from South America
Step-by-step explanation:
In order to find the answer to this, you need to make the denominators of the North American and African species the same.
To do this, multiply 1/4 x 2/2.
You would then get 2/8. This means 2/8 of the species are African
Since you now have the same denominator, add the fractions together, and the total amount of North American and African species is 7/8, leaving 1/8 for the South American species.
You would then divide 64 by 8 to see how much 1/8 is worth in terms of how many species, and would then get 8.

What is the equation of the line in point-slope form?
Answer:
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]
Step-by-step explanation:
Given
The attached graph
Required
Determine the equation in point slope form
From the graph, we have the following points;
[tex](x_1,y_1) = (-400,-400)[/tex]
[tex](x_2,y_2) = (100,-500)[/tex]
First, we calculate the slope (m):
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-500 - (-400)}{100- (-400)}[/tex]
[tex]m = \frac{-500 +400}{100+400}[/tex]
[tex]m = \frac{-100}{500}[/tex]
[tex]m = -\frac{1}{5}[/tex]
The equation is then calculated using:
[tex]y - y_2 = m(x - x_2)[/tex]
Substitute x and y values
[tex]y - (-500) = -\frac{1}{5}(x - (100))[/tex]
[tex]y +500 = -\frac{1}{5}(x - 100)[/tex]

WILL AWARD BRAINLIEST TO THE CORRECT ANSWER!!
Answer:
Solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]
Step-by-step explanation:
We need to solve the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex]
We know that [tex]\sqrt{x} = x^{\frac{1}{2}}[/tex]
Solving:
[tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}\\=((\sqrt{21}-2\sqrt{7} )^2)^\frac{1}{2}[/tex]
We know that [tex](a^2)^\frac{1}{2}=a[/tex]
= [tex]\sqrt{21}-2\sqrt{7}[/tex]
So, solving the expression: [tex]\sqrt{(\sqrt{21}-2\sqrt{7} )^2}[/tex] we get [tex]\sqrt{21}-2\sqrt{7}[/tex]
12. Find the values of x and y in the diagram below.
Answer:
x = 15
y = 19
The value of the x and y are; 11/6, -5 and 18/4 in the linear equation.
What is linear equation?The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given parameters;
The equations are;
(4y - 18)
(6x - 11)
(x + 5)
Now put all equation equal to zero.
Then;
4y - 18 = 0
y = 18/4
And then;
6x - 11 = 0
x = 11/6
And
x + 5 = 0
x = -5.
Hence, In the linear equation, value of the x and y are 11/6, -5 and 18/4.

identify the slope and y-intercept of the function y=-5x+4 (brainlyest to correct answer)
Answer: A. The slope is -5, and the y-intercept is (0,4)
Step-by-step explanation:
In standard form, a function is written as y = mx + b, where m = slope and b = the y-intercept
With that in mind, the m value is -5 and the b value is 4
Thus, the slope is -5, and the y-intercept is (0,4)

Line m has a slope of -5. What is the slope of a line parallel to line m?
Answer: -5
Step-by-step explanation:
parallel lines have equal/same slope
You are at a European beach with 60 other visitors. 36 of them speak English. If you randomly meet two people on the beach, what is the probability that they both speak English
Answer:
Assuming I'm one of the 36 English speakers and the other 24 speak Spanish for illustration purposes. The problem can be modeled as 59 marbles with 35 E and 24 S marbles as N = 59 possible outcomes = n(E) + n(S) = 35 + 24.
So I reach into the pile of marbles (on the beach) and the probability that it's p(E) = n(E)/N = 35/59 = 0.593220339 when I meet the one person. ANS
I assume I remember that first person; so I remove him from the marbles (by avoiding him on the beach) and now my probability is p(E and E) = n(E)/N * n(E)-1/(N - 1) = 35/59*34/58 = 0.347749854 ANS
Following the same logic p(E and E and E) = 35/59*34/58*33/57 = 0.201328863 ANS
This last one is different from the first three. This one is p(E >= 1|4 attempts). We can trace out a probability tree to identify those branches that contain at least one E event. So:
EEEE p() = 35/59 * 34/58 * 33/57 * 32/56 =
EEES p() = 35/59 * 34/58 * 33/57 * 24/56 =
EESE p() = 35/59 * 34/58 * 24/57 * 33/56 =
ESEE p() = 35/59 * 24/58 * 34/57 * 33/56 =
SEEE p() = 24/59 * 35/58 * 34/57 * 33/56 =
EESS p() = 35/59 * 34/58 * 24/57 * 23/56 =
ESES p() = 35/59 * 24/58 * 34/57 * 23/56 =
SEES
SESE
SSEE
ESSS And so on, but...a big BUT...why do all this when
SESS
SSES
SSSE
SSSS
p(E>=1|4) = 1 - p(S and S and S and S) = 1 - 24/59 * 23/58 * 22/57 * 21/56 = 0.976652619 ANS. In other words we find the probability of not meeting an Englishman and take 1 minus that value to find the probability of meeting at least one.

Who knows the answer for this question
Answer: 7
Work: So, the goal is to get z alone, so we are going to add 85 on both sides, cancelling on the side it's currently on. So, the new equation is going to be 25z = 175. Then, to get z even more lonely, we are going to divide 25 on both sides, and again cancelling it on the side it's currently on. So, the answer is z = 7. I hope this helps, and Happy Holidays! :)
