Answer:

458 g144 g

Step-by-step explanation:

As per equation, the initial amount is:

A(0) = 458*(1/2)^(0/30) = 458*1 = 458 g

Sample amount left after 50 years:

A(50) = 458*(1/2)^(50/30) = 144 g (rounded)

Which is a direct variation equation?

1. Y=x+5
2. Y=-5/x
3. Y=-5x
4. Y=x-5

Help

Answers

Answer:

3. y = -5x

Step-by-step explanation:

In a direct variation equation, the constant of proportionality (k) is a direct coefficient of the variable x.

Y will be set equal to x multiplied by this coefficient.

Since y = -5x directly relates x to y, with the constant of proportionality, it is a direct variation equation.

So, 3. y = -5x is the correct answer.

Answer:

23.4

Step-by-step explanation:

The area of the triangle is 23.55 in².

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

ΔWXY

w = 6.7 inches

x = 7.4 inches

∠Y = 71°

Now,

The area of the triangle.

= 1/2 (wx) siny

= 1/2 x (6.7 x 7.4) x sin 71
= 1/2 x 49.58 x 0.95

= 23.55

Thus,

The area of the triangle is 23.55 in².

Answer:

v = 9 m

Step-by-step explanation:

the formula for the perimeter is P = 2W + 2L.

Here the perimeter is 42 m = 2(12 m) + 2v. Solving for 2v, we get:

42 m - 24 m = 2v, or

v = 21 m - 12 m, or

v = 9 m

Answer:

vertical opposite angles are always equal

co-interior angles are supplementary ( 180° )

∴ x = 180 - 143 = 37

PLEASE HELP I NEED IT TO PASS THIS CLASS

Answers

Answer:

Angle 5 = 37°

Angle 8 = 143°

Step-by-step explanation:

Angle 2 = Angle 8

Reason : Alternate exterior angles are equal.

Therefore,

Angle 8 = 143°

Angle 5 + Angle 8 = 180°

Reason : Angle 5 & 8 are in a linear pair.

Angle 5 + 143° = 180°

Angle 5 = ( 180 - 143 )°

Angle 5 = 37°

Answer:

it's 8

Step-by-step explanation:

(10×1/5)^3=2^3=8

Answer:

The answer is 8!

Step-by-step explanation:

Subtract the like terms. As you can see, the 10 in the numerator and denominator have the same base. Therefore, you can subtract the exponents, which would be 10^1, or 10. You would do the same for 5, which would be 5^-1, or 1/5. You would then make this one fraction, the 10 and 5. The fraction would be 10/5, or 2 once simplified. Now, don't forget the outside parentheses! You would do 2^3, and your final answer would be 8. Hope this helps!

Problem PageQuestion A theater group made appearances in two cities. The hotel charge before tax in the second city was $1500 lower than in the first. The tax in the first city was 10%, and the tax in the second city was 8%. The total hotel tax paid for the two cities was $825. How much was the hotel charge in each city before tax?

Answers

Answer:

the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

Step-by-step explanation:

Let a represent the charge in the first city before tax and b represent the charge in the second city before tax.

Therefore tax in first city = 10% of a = 0.1a

Tax in second city = 8% of b = 0.08b

From the total tax as $825, hence:

0.1a + 0.08b = 825 (1)

The hotel charge before tax in the second city was $1500 lower than in the first. This gives the equation:

b = a - 1500

a - b = 1500 (2)

To find a and b, solve equation 1 and 2 simultaneously. Multiply equation 2 by 0.1 and subtract from equation 1:

0.18b = 675

b = $3750

a = b + 1500 = 3750 + 1500 = 5250

a = $5250

Therefore, the hotel charge in the first city is $5250 while the hotel charge in the second city is $3750

F 5 1.25 + b
G5 < 1.25 + b
H 5 > 1.25b
J 5 < 1.25b

Answers

Answer:

The answer would be letter J

The inequality for total expenditure & number of breakfasts is 5 > 1.25b

Formulation of inequality equation for expenditure & breakfasts

Assumed : Number of breakfasts = b

Number of breakfast meals x Price per breakfast meal = Total Expenditure

Total expenditure should be less or than equal to $1.25

So, 1.25b < 5

It implies that inequality : 5 > 1.25b
