Themla spent 1/6 of her weekly allowance on dog toys. 1/4 on a dog collar, and 1/3 on dog food. What fraction of her weekly allowance is left?

Answers

Answer:

¼ remaining

Step-by-step explanation:

Convert to common numerator of 12:

1/6 = 2/12

1/4 = 3/12

1/3 = 4/12

Total: 9/12

1 - 9/12 = 3/12 = ¼

For the triangle shown, find sec x

Answers

You have the three basic trig functions: sine, cosine, and tangent.
Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent

You have three other trig functions: secant, cosecant, and cotangent.
Cosecant = hypotenuse/opposite
Secant = hypotenuse/adjacent
Cotangent = adjacent/opposite

The way I’ve always remembered these is the 3 other trig functions are sine, cosine, and tangent flipped. Sine’s opposite is cosecant. Cosines opposite is secant, and tangents opposite is cotangent.

If you notice, each of these functions has a word starting with co-, and a word starting without co-. That’s how I’ve always remembered that sine goes to cosecant and cosine goes to secant.

Now that we know secant (or sec for short) x = hypotenuse/adjacent, you can find it.

First, find the hypotenuse of the triangle. Use Pythagorean’s theorem to do this.

a^2 + b^2 = c^2
5^2 + 7^2 = c^2
25 + 49 = c^2
c^2 = 74
c = √74

Now plug the values for hypotenuse and adjacent into sec(x)
sec(x) = √74/7

Answer:

Step-by-step explanation:

Using the Pythagorean Theorem, (7)2 + (5)2 = c2 ⇒ c = 72

.

Since x =  1 /cos x =  hypotenuse /adjacent , then sec x = √ 74/7

Answers

Answer:

A is false it said it could be greater than 35 or equal to and 100 x 5 = 500 + 1 = 501 therefore a is false

B is false 6.8 could be possible and it could be a decimal it can't only be a whole number

C is false 6 4/5 is a solution so c is false

D is I'm not sure, I think infinite except for 7 and below so maybe true

E is false because any number greater than 7 that are multiplied to 5 can be as long as its greater than or equal to 35

Ok this is what I think. Id rather wait for more answers to be sure thank you.

Answers

Answer:

c

Step-by-step explanation:

Answer:

A factor is a circumstance or action that will/would influence an outcome.

A variable is something that is liable to change or something that isn't temporary.

A product is a result of an action or a process.

Coefficient means a quantity is being multiplied by the variable, for instance:

4 (the coefficient) X (the variable) - (the operator) 7 (the constant) = 5 (the constant)

What that looks like is: 4x-7=5.

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.

Answers

Answer:

10.3 is the width

Step-by-step explanation:

set up an equation

42w=432

divided both sides by 42

W=10.2857142857

to rounded it to nearest tenth it will be 10.3

to check your answer multiply 10.3 by 42 it will be 432

check check

Answer:

18 ≤ w ≤ 24

Step-by-step explanation:

A = l * w

A ≥ 432 sq ft.

l = 42 - w

432 ≤ (42 - w) (w)

432 ≤ -w² + 42w

w² - 42w ≥ 432

Substitute values for w

w = 18

w = 24

Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 30 miles at a speed of 6 mph, while Bob's motorboat traveled 70 miles at a speed of 14 mph. For how long were Niles and Bob traveling?

Answers

Answer: 5 hours

Step-by-step explanation:

As both of them sailed for the same time, take the speed and distance of either of them to find the time they traveled:

Niles' Time = Distance / speed

= 30 / 6

= 5 hours

Bob's time = 70 / 14

= 5 hours

X = ?

Answers

Answer:

x = 3

Step-by-step explanation:

The midsegment is half the sum of the parallel bases, that is

[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13

[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )

7x + 5 = 26 ( subtract 5 from both sides )

7x = 21 ( divide both sides by 7 )

x = 3
