Suppose you know the perimeter of a rectangle. How can you write

an equation for the area in terms of the length of a side?

Answers

Answer 1

Step-by-step explanation:

L+W+L+W=26 so 2L=26–2W and you can find length from the perimeter as L=13−W

LW=42 so L=42/W is the other way to find the length, from the area. Both ways require you to know W, but if you have both pieces of information the two answers for length must be the same 42/W=13−W, and you solve this:

42=13W−W2

W2–13W+42=0

(W−6)(W−7)=0

Either W−6=0 or  W−7=0

What’s the equation of the blue line?

Answers

Answer:

x + 2y = 4

Step-by-step explanation:

Line is passing through the points (4,0) and (0, 2)

Slope of line (m) = (2 - 0)/(0-4) = 2/(-4) = - 1/2

y - intercept (b) = 2

Equation of line in slope intercept form is given as:

y = mx + b

Plugging m = - 1/2 and b = 2 in the above equation, we find:

[tex]y = - \frac{1}{2} x + 2 \\ \\ 2y = - x + 4 \\ \\ x + 2y = 4[/tex]

Answer: x+2y=4

Cuboid ABCDEFGH is shown
BC=6.8
DE=9.3
Find the size of the angle between CF and the Plane ABCD
NEEDS ASAP WILL MARK AS BRAINLIEST IF CORRECT

Answers

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°

If you assume doubling the workers will halve the time taken to finish then 12 analysts will take 21 days
To finish in 7 days (1/6 of 42 days) you would need 6 x the original number = 36 analysts.

One reason is the extra people tend to get in each others way.

Please help, I'm having a hard time with this ;-;

Answers

Answer:

A

Step-by-step explanation:

3 times steep means slope is 3 times

slope=4

new slope =3×4=12

translated 7 down means y intercept-7=1-7=-6

so new eq. is y=12x-6

Answer:

A

Step-by-step explanation:

So we know that the slope is 4, and we want to make it 3 times as steep, so that would be 12. The y-intercept is one and we want to move it down 7 units, 6-7= -1. So our final answer would be y= 12x-6!

Each gridline represents one mile. If Ryan drove from home to the soccer field and then from the soccer field to the library, traveling in a straight line to each destination, he would have traveled ___ miles by the time he reached the library.

Answers

Answer:

13 miles

Step-by-step explanation:

Given that he traveled in a straight line to each destination. Then,

i. distance from his home to soccer field = [tex]\sqrt{x^{2} + y^{2} }[/tex]

                                      = [tex]\sqrt{4^{2} + 3^{2}}[/tex]

                                      = [tex]\sqrt{16 + 9}[/tex]

                                      = [tex]\sqrt{25}[/tex]    = 5 miles

ii. The distance from soccer field to the library = 8 miles.

So that we can say that;

Ryan's total distance from home to the library = 5 + 8

                                                      = 13 miles

Thus, Ryan would have traveled 13 miles by the time he reached the library.

A dessert of both yogurt and idiots were together in the ratio of 1:4 the idiot had 45 said LISA (lol)

Answers

Answer:

11.25

Step-by-step explanation:

Ratio of yogurt : ratio of idiot = 1 : 4

Idiot had 45

Yogurt = x

Ratio of yogurt : ratio of idiot = x : 45

Equate the ratios

1 : 4 = x : 45

1/4 = x/45

Cross product

1 * 45 = 4 * x

45 = 4x

x = 45/4

x = 11.25

Yogurt = x = 11.25

Greatest angle measure is ∠Q

Smallest angle measure is ∠R

Step-by-step explanation:

As the length of side are in the same order as the measure of the angles opposite the lengths of sides. The greatest side is opposite to the greatest angle.

By using the properties of triangle , if one angle of a triangle is larger than the other angle, then the side opposite to the larger angle is greater than the side opposite to the smaller angle.

Longest side=PR=13cm

∴ Greatest angle measure is ∠Q

Smallest side=PQ=8cm

∴ Smallest angle measure is ∠R
