Answer:

1/20

Step-by-step explanation:

1/4 = 0.25

0.25 / 5 = 0.05

0.05 as a fraction = 5/100

simplified

5 / 5 = 1

100 / 5 = 20

Answer:

39

Step-by-step explanation:

[tex]\sqrt{100-36}+32-1\\\sqrt{64}+31\\8+31\\39[/tex]

Hey there!

√(100 – 36) + 32 – 1

= √(64) + 32 - 1

= 8 + 32 – 1

= 40 – 1

= 39

Therefore, the answer should be: 39

The answer is

for parallel : y= 4/7-5x/7

for perpendicular: y=10+7x/5

The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.

Given line: 5x+7y=9

when our intersection point is (5,-3) the constant

5x+7y

= 5(5)+7(-3)

= 25-21

=4

hence, 5x+7y=4

slope intercept form

7y= 4-5x

y= 4/7-5x/7

Now, for perpendicular lines:

swap the coefficients on x and y with negative sign of x in  5x+7y=9

7x-5y= constant

again, when our intersection point is (5,-3) the constant must be

7x-5y

= 7(5)-5(-3)

=35+15

=50

7x-5y=50

slope intercept form so we solve for y:

y= (50+7x)/5

y=10+7x/5

By using the information given on the graph, we can see that a = 3.

Here we have an exponential of the form:

[tex]y = p*a^x[/tex]

And by looking at the graph, it passes through (0, 4) and (2, 36), so we can write:

[tex]4 = p*a^0\\\\36 = p*a^2[/tex]

From the first equation we get that p = 4, replacing that on the second one we get:

[tex]36 = 4*a^2\\\\36/4 = 9 = a^2\\\\\sqrt{9} = 3 = a[/tex]

So we conclude that a = 3.

Answer:

see below

Step-by-step explanation:

You will need the hypotenuse   12 ^2 + 9^2 = h^2   h = 15

In a right triangle:

S O H   C A H  T O A

sin s  =   S A H  = Opposite / Hypotenuse =   12/15

cos r = C A H  = Adjacent / Hypotenuse    = 12/ 15

Tan s = T O A =  12 / 9

cos (theta) = cos s  = 9 / 15

Tan r = 9/12

arc cos(theta) = theta = arccos(9/15) = 53.13 degrees

a) Angles ACB in ∆ABC and ECD in ∆EDC are congruent, since they form a vertical angle pair.

Angles ABC and EDC are clearly congruent, since they are both right angles.

The legs AB and ED are parallel, so angles BAC and DEC are congruent alternating interior angles.

Then ∆ABC is similar to ∆CDE by the angle-angle-angle postulate.

b) Because they're similar, corresponding sides occur in a fixed ratio, which tells us that

CD/BC = ED/AB

Answer:

red marbel

green marbel

[tex] = \frac{9}{26} [/tex]

Step-by-step explanation:

for the red marbel you first add all the number of balls given and the total is 26 then you take the number of red marbels dividing the total number of all the balls and if you are able to cancel out you can and there you get your answer same applies to the green marbel

A rectangular fence is to a total perimeter of 200 feet. If the length is twice the width, find the measurements of the length and width of the rectangular fence.

In this question we are provided with the perimeter of a rectangle fence that is 200 feet. It is also given that the length of the fence is twice its breadth. We are asked to calculate it's dimensions.

First we will form an equation.

Let us assume the breadth as x

Then, length = 2x

It is given that the perimeter is 200 feet.

We know,

[tex] \bull \: \small\boxed{ \rm{ Perimeter_{(rectangle)} = 2(length + breadth)}}[/tex]

Substituting the values we get

[tex] \small\sf{ 200 = 2(2x + x)}[/tex]

Now we will solve this equation and find out the value of x.

[tex] \small\sf{ 200 = 2(2x + x)}[/tex]

[tex] \longmapsto \small\rm{ 200 = 2(3x )}[/tex]

[tex] \longmapsto \small\rm{200 = 6x} [/tex]

[tex] \longmapsto \small\rm{ \dfrac{ \cancel{200} \: \: 33.33}{ \cancel{6}} = x } [/tex]

[tex] \small\sf{x = 33.33} [/tex]

We will substitute the value of x = 33.33.

Length = 2x = 2 × 33.33 = 66.66 feet

Breadth = x = 33.33 feet

Answer:

C is the answer

Step-by-step explanation:

C. is only saying how farming seasons would be longer and is not an example of how climate change has impacted the Earth.

Answer:

I believe the answer to your question is the third answer (C).

Step-by-step explanation:

The reason why I chose the third answer is because the destruction of coral reefs is bad because multiple organisms in the water rely on them and if it's destroyed there will be a chain reaction with the ecosystem in a bad way. In addition, it is also not an extinction risk for animals because it is also a disadvantage because biodiversity will decrease and that will also cause problems. I believe a longer farming season is the answer because food and other things that farmers have to grow will last for longer periods of time and won't really disrupt anything going on in the ecosystem I think. I hope this helps although it may be wrong. I am not an expert when it comes to this type of stuff.

In the first circle, x is the radius and also the hypotenuse of a right triangle with legs measuring 9 and 12. So by the Pythagorean theorem,

x² = 9² + 12² = 225 = 15²  ⇒   x = 15

In the second circle, the chords AB and CD have the same length, and each of AP, BP, CP, and DP are radii of the circle and also have the same length. This means ∆ABP and ∆CDP are congruent, so the two labeled angles are also congruent, so x = 54.

Answer:

x = 66

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

x + 35 + 79 = 180 , that is

x + 114 = 180 ( subtract 114 from both sides )

x = 66
