3. Elena walked 12 miles. Then she walked 0.25 that distance. How far did she walk all together? Select all that apply.
A. 12 + 0.25 ⋅ 12
B. 12(1 + 0.25)
C. 12 ⋅ 1.25
D. 12 ⋅ 0.25
E. 12 + 0.25

Answers

Answer 1

Answer:

A, B, C

Step-by-step explanation:

12+0.25*12=12(1+0.25)=12*1.25

Answer 2

Answer:

B. 12 + 0.25 ⋅ 12

C. 12(1 + 0.25)

Step-by-step explanation:

It asks you how far she walks all together, so you need to find that answer first to figure out the rest correctly. Now, the total she walked is 15 miles. B. and C. give you 15, however, the rest give you different answer than the total she actually walked.

A rectangle has perimeter 200 feet.
1. Let L represent the length of the rectangle. Write an equation for the width W in terms of L.
2. Write a function A(L) that represents the area of the rectangle with length L.​

Answers

Answer:1. (200-2L)/2      2.L x (200-2L)/2=A

Step-by-step explanation:

Answer:

Part 1)

[tex]W=100-L[/tex]

Part 2)

[tex]A(L)=L(100-L)[/tex]

Step-by-step[tex]W = 100-L[/tex] explanation:

We are given a rectangle with a perimeter of 200 feet.

Part 1)

The formula for perimeter for a rectangle is:

[tex]200=2(L+W)[/tex]

We can divide both sides by 2:

[tex]100=L+W[/tex]

And subtracting L from both sides yields:

[tex]W=100-L[/tex]

Part 2)

The area of a rectangle is given by:

[tex]A(L)=LW[/tex]

Since we solved for W earlier:

[tex]A(L)=L(100-L)[/tex]

In ΔKLM, l = 820 cm, m = 560 cm and ∠K=169°. Find the length of k, to the nearest centimeter.

The length of the side k in the given triangle is 1,373.9 cm.

What is cosine law?

The law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles.

Given that, in ΔKLM, l = 820 cm, m = 560 cm and ∠K=169°, we need to find the length of side k,

Using the cosine law,

k² = l²+m² - lmCos169°

= 820²+560²-(820)(560)cos169°
= 1,373.9

Hence, the length of the side k in the given triangle is 1,373.9 cm.

Find the value of X.

Answers

To find the value of x we first need to find the missing angle in the triangle.

To do that we are gonna add the angles we already have.

64 + 45 = 109

Angles in a triangle measures 180 so to get the missing angle we are gonna subtract 109 from 180

180 - 109 = 71 deg

The missing angle in the triangle is 71 deg


Angles on a straight line adds up to 10 so to find x we are gonna subtract 71 from 180

180 - 71 = 109 degrees

Therefore x is 109 degrees.

5 divided 9/10 in fractions forms

Answers

Answer: 5 5/9

Step-by-step explanation:

cause that’s the answer

5 divided by 9/10, in fraction form, is 50/9.

To divide 5 by 9/10, we can convert the whole number 5 into a fraction with a denominator of 1.

5 can be expressed as 5/1.

We can rewrite the division problem as a multiplication problem by taking the reciprocal (flipping the numerator and denominator) of the divisor:

5/1 ÷ 9/10

= 5/1 × 10/9

Multiply the numerators together and the denominators together:

(5×10) / (1 × 9) = 50/9

Therefore, 5 divided by 9/10, in fraction form, is 50/9.

If Holly gets 14 % off a shirt , what percent of the original price will still pay​

Answers

Answer:

Holly will still pay 86% of the original price.

Step-by-step explanation:

Given

Holly gets 14% off a shirt, soDiscount = 14%

To determine

What percent of the original price will still pay.

All we need is to subtract the percentage of discount from 100.

i.e.

100 - Discount = 100 - 14 = 86%

The amount left over would be what remains of the original price after Holly gets 14 % off a shirt.

Thus, Holly will still pay 86% of the original price.

Solve the inequality for x.


x-c/d > y (for d > 0)

Answers

The solution for x of the inequality x-c/d > y (for d > 0) is x > d * y + c.

Here,

To solve the inequality for x, we'll isolate x on one side of the inequality:

Given inequality: (x - c) / d > y

First, we'll multiply both sides of the inequality by d to get rid of the fraction.

Remember that since d > 0, we don't need to reverse the inequality:

d * [(x - c) / d] > d * y

Next, the d on the left side cancels out, and we have:

x - c > d * y

Now, to isolate x, we'll add c to both sides of the inequality:

x - c + c > d * y + c

x > d * y + c

So the solution for x is x > d * y + c.
