Bob has 30 coins, which are all dimes and quarters. If the total amount of money he has
is $4.80, how many of each coin does he have?

The amount of money that Romania’s imports are worth is equal to: C. $76.17 billion.

Given the following data:

Exports tariff = 6% = 0.06.

Imports tariff = 21% = 0.21.

Trade deficit = $26.76 billion.

Tariff revenue = $18.9603 billion.

In order to determine how much Romania’s imports are worth, we would write a mathematical expression for the total tariff revenue and trade deficit as follows:

0.06E - 0.21I = 18.9603    .....total tariff revenue (eqn. 1).

I - E = 26.76                       .....trade deficit (eqn. 2).

From eqn. 2, we have:

E = I - 26.76     ..equation 3.

Substituting eqn. 3 into eqn. 1, we have:

0.06(I - 26.76) - 0.21I = 18.9603

0.06I - 1.6056 - 0.21I = 18.9603

0.27I = 18.9603 + 1.6056

0.27I = 20.5659

I = 20.5659/0.27

I = $76.17 billion.

Answer:

7/8

Step-by-step explanation:

I took the test

The total weight of the dog toys that weighed 1/8 of a pound or 3/8 of a pound is 7/8.

Let we have to add two fractions:

[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]

Then we will find the Lowest Common Multiple (LCM) of   b_1 and

b_2. That will help to make the denominate or same.

Once the denominators become the same, the numerators can add up directly, giving us the final result of the addition.

According to the line plot;

The total weight of the dog toys that weighed 1/8 of a pound or 3/8 of a pound

= 3/8 + 3/8 + 1/8

=7/8

c=31.4

So the diameter is 31.4 meters.

Answer:

16.33 km

Step-by-step explanation:

The square length of hypotenuse is equal to the sum of two legs' square value:

|HI|^2 + |JI|^2 = |HJ|^2

|HI|^2 + (24.28)^2 = (29.26)^2

|HI|^2 + 589,5184 = 856,1476 (these are full values and will be easier to calculate with a calculator, if not we can use the approximate values: 589,5 and 856,1)

subtract 589,5184 from both sides

|HI|^2 = 266,5636 find the root of boths sides

HI = 16.33 approximately

The base HI of the right triangle is approximately 16.26 km.

Given is a right triangle with perpendicular JI = 24.28 km and hypotenuse HJ = 29.26 km we need to find the base HI.

To find the base HI of the right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Let's denote the base HI as x.

According to the Pythagorean theorem:

HJ² = JI² + HI²

Substituting the given values:

(29.26 km)² = (24.28 km)² + x²

Simplifying the equation:

855.4276 km² = 590.7584 km² + x²

264.6692 km² = x²

To find x, we take the square root of both sides:

x = √(264.6692 km²)

Calculating the value:

x ≈ 16.26 km

Therefore, the base HI of the right triangle is approximately 16.26 km.

Answer:

It's 13<26

Step-by-step explanation:

Answer:

Harper is 17 and Cadence is 44.

Step-by-step explanation:

First, we can set up an equation to displays the sum of both ages.

Let x = Harper's age and y = Cadence's age

x+y=61

8 years ago, this means the sum will decrease by a total of 16 as we have to subtract 8 from both variables

The equation to represent 8 years ago is: x+y=45

Now we can write another equation to represent Cadence being 4 times older than Harper (8 years ago)

y=4x

We can substitute this back into the equation we had for the ages 8 years ago.

x+(4x) = 45

5x=45

x=9

Now, Harper's age 8 years ago is 9 years old. We add 8 to this number to determine that Harper is currently 17 years old.

We can insert this into the original equation to determine Cadence's age.

17+y=61

y=44

Thus, Cadence is currently 44 years old
