Answer:

Q. 2)Perimeter =2(l+b)

So,

2(8x-8 +8x)=80cm(Given in Question)

= 2*16x-8=80cm

16x- 8= 80 divided by 2,

16x=40+8=48

x=48 divided by 16

X=3

Q.1) Perimeter=2(l+b)

2(2x+8 +4x)=76cm(Given in Question)

2* 6x +8=76

6x+8= 76 divided by 2, 38

6x= 38-8, 30

x= 30 divided by 6 = 5

X=5

T-shirts that usually sell for $28.99 are on sale
for $17.39. What percent off are they?

Answers

Answer: i think it is  46.38 %

Step-by-step explanation: add both numbers ( decimals) and just put the percentage. hope this will help u stay safe :)

Answer:

38.3%

Step-by-step explanation:

We have two equations to find the answer.

1. Discount = OG Price * Discount by 100%

2. Final Price = OG Price - Discount

So fill in the first equation :

Discount = 28.99 * 38.3/100

Discount = 28.99 * 0.38

Saved = $11.10

Now for the second equation :

Final Price = 28.99 - 11.10317

Final Price = $17.89

Therefore the discount is 38.3%

Both C and D are similar

Step-by-step explanation:

The are similar because each of the sides are proportional to each other. On letter C the scale factor of each side is 1.2. To get from the first triangle to the second, they multiplied each side by 1.2 and ended up with a slightly larger triangle. The same thing happens on the second one except for it is slightly smaller with a scale factor of 1/2.

The polar form of the given complex number is:

[tex]W = \sqrt{12}* e^{-i*0.52}[/tex]

How to get the polar form of the complex number?

Here we have:

W = -3 + √3i

To get the polar form we first need the module of W it is:

|W| = √( (-3)^2 + (√3)^2) = √12

And now we need to find the bearing, that is given by the Arctangent of the quotient between the imaginary part and the real part.

Arctan(√3/-3) = -0.52 rad

Then the polar form is:

[tex]W = |W|*e^{-i*0.52} = \sqrt{12}* e^{-i*0.52}[/tex]

The vegetable garden has 95 ripe plants. The number of tomatoes is 16 fewer than twice the number of squashes. How many of each vegetable are ripe?​

Answers

Answer:

Tomatoes = 39.5

Squash = 55.5

Step-by-step explanation:

T (tomatoes) = S - 16

S + T = 95

we plug it in now

S + (S - 16) = 95

2s = 95 + 16

2s = 111

s = 55.5??

hm. Let's go with it

T = 55.5 - 16

T = 39.5

39.5 + 55.5 = 95
