What is the solution to the system of equations

Answer:

78.79°

Step-by-step explanation:

A fireman placed a ladder of length 36 feet against a building.

Now, if he placed the ladder 7 feet from the base of the building, then the angle formed between the ladder and the ground will be [tex]\theta[/tex] (Say).

Now, the ladder, the base ground and the building forms a right triangle and the ladder is the hypotenuse of the triangle and [tex]\theta[/tex] is the base angle.

So, [tex]\cos\theta = \frac{\textrm {Base length}}{\textrm {Ladder length}} = \frac{7}{36}[/tex]

⇒ [tex]\theta = \cos^{-1}(\frac{7}{36}) = 78.79^{\circ}[/tex] (Answer)

4. You get -360

There is only one unique triangle that can be drawn with a 35° angle and a 45° angle, as the third angle is determined to be 100° to make the sum 180°.

To determine how many different triangles can be constructed with a 35° angle and a 45° angle, we can use the fact that the sum of angles in a triangle is always 180°. Adding the given angles, we get 35° + 45° = 80°. Subtracting this from 180° gives us the third angle, which is 180° - 80° = 100°. Since the sum of the angles is 180° and all angles are determined, there is only one unique triangle that can be drawn with these angle measures

The cost per can of Diet Coke is cheaper at Wal-Mart than Kroger. Wal-Mart sells a can for approximately $0.287, while Kroger sells a can for approximately $0.3325. Therefore, Wal-Mart is the best buy.

To determine the best buy between Wal-Mart and Kroger, we need to calculate the price per can of Diet Coke for each store.

For Wal-Mart, the case contains 24 cans for $6.88. So, we divide the total cost by the number of cans: $6.88 ÷ 24 = $0.287 per can

For Kroger, the pack contains 12 cans for $3.99. So, again we divide the total cost by the number of cans: $3.99 ÷ 12 = $0.3325 per can

Comparing the two prices, $0.287 per can from Wal-Mart is cheaper than $0.3325 per can from Kroger. Therefore, buying the case of Diet Coke from Wal-Mart is the best buy.

Answer:

The percent of change is 20%.

And it is increased by last month.

Step-by-step explanation:

Given:

The ice cream parlor has 30 flavors, but for the last week they have only had 25 flavors.

Now, to find the percent of change.

Flavors ice cream parlor has = 30.

Flavors last week they had = 25.

So, the flavors increased from last week by:

[tex]30-25=5\ flavors.[/tex]

Now, to get the percent of change:

[tex]\frac{5}{25} \times 100[/tex]

[tex]=\frac{500}{25}[/tex]

[tex]=20\%.[/tex]

Thus, the percent of change is 20%.

The flavor is increased by last month.

Therefore, the percent of change is 20%.

And it is increased by last month.

Final answer:

The percent of change is a decrease of 16.67%, calculated by subtracting the new amount of flavors from the original, dividing by the original amount, and multiplying by 100.

Explanation:

To find the percent of change in the number of flavors at the ice cream parlor, we will subtract the original amount of flavors from the new amount, divide that by the original amount, and then multiply by 100. The original amount of flavors was 30, and the new amount is 25. Here is the calculation:

Subtract the new amount from the original amount: 30 - 25 = 5

Divide the change by the original amount: 5 ÷ 30 = 0.1667

Multiply by 100 to get the percent: 0.1667 x 100 = 16.67%

The percent of change is a decrease of 16.67% since the number of flavors went down from 30 to 25.

Step-by-step explanation:

If each lap is one mile, 18 times = 1/6 + 1/6 + ... + 1/6. This is equal to 18*1/6 by definition of multiplication, and 18*1/6 = 18 divided by 6 because fractions are just big division symbols. This gives 3 or 3 miles.

Answer:

Explanation:

Three or more points are collinear if and only if they are on the same line, and, thus they are solutions, of the same equation of the line.

When you know two points through their coordinates you can always find the equation of the line:

You can find the slope, m, of that line by using the slope formula:

And then, you apply the point-slope equation:

Since you know m, x₁, and y₁, your equation is determined.

Once you have your equation, substitute the x and y coordinates with the coordinates of the point C. If, and only if, the equation is satisfied, the point C is on the same line and the three points are collinear.

Answer:

Toby wants to find the volume of a solid toy soldier.He fills a rectangular container 8 cm long, 6 cm wide,and 10 cm high with water to a depth of 4 cm. Toby totally submerges the toy soldier in the water. The height of the water with the submerged toy soldier is 6.6 cm. Which of the following is closest to the volume, in cubic centimeters, of the toy soldier?

A. 125 B. 156 C. 192 D. 208 E.317

The volume of the toy is 125 cubic cm ,option A is the closest answer.

Step-by-step explanation:

Given:

A rectangular container .

Length of the container =8 cm

Width of the container = 6 cm  

Height of the container when water is filled = [tex](h_1)[/tex] = 4 cm

Height of the container when the toy is submerged = [tex](h_2)[/tex] =6.6 cm

Volume of the toy =  Volume of the container with the toy - Volume of the container (with water)

Volume of the toy = [tex](l\times b\times h_2) - (l\times b\times h_1)[/tex]

                              = [tex](l\times b\times)(h_2-h1)[/tex]

                              = [tex](6\times 8)(6.6-4)[/tex]

                              = [tex]48\times 2.6[/tex]

                              = [tex]124.8[/tex] cubic centimeters.

So,the closest value to the volume of the toy is 125 cubic centimeters.

The closest volume, in cubic centimeters, of the toy soldier is 124.8 cm³.

To find the volume of the toy soldier submerged in water, we can use the following steps:

1. Calculate the initial volume of water in the container: 8 cm x 6 cm x 4 cm = 192 cubic cm.
2. Determine the final volume of water with the toy soldier submerged: 8 cm x 6 cm x 6.6 cm = 316.8 cubic cm.
3. Subtract the initial volume of water from the final volume with the toy soldier submerged: 316.8 cubic cm - 192 cubic cm = 124.8 cubic cm.

Therefore, the closest volume, in cubic centimeters, of the toy soldier is 124.8 cm³.

Answer:

5.5.5.5

= 5^4

=625

Explanation:

5 to the power of 4 is equal to 625

Redefined format 5.5.5.5 as 5 * 5 * 5 * 5, converted to exponential notation as 5^4. The base is 5, exponent is 4, showing multiplication of the base 4 times.

The number 5.5.5.5 that you've provided seems to have a format error considering the extra dots you've used. If by any chance you meant 5 * 5 * 5 * 5, it in exponential notation is 54. '5' is the base and '4' is the exponent, the latter representing the number of times the base is multiplied by itself. In this case 5 is multiplied by itself 4 times.

Final answer:

The number 13,809 in expanded form is expressed as 10,000 + 3,000 + 800 + 9, which corresponds to option 'D'.

Explanation:

To write the number 13,809 in expanded form, we break the number down into its place values and then write it as a sum of each digit multiplied by its place value. For the number 13,809 this would be:

(1 × 10,000) for the ten-thousands place,

(3 × 1,000) for the thousands place,

(8 × 100) for the hundreds place,

(0 × 10) for the tens place (which is actually 0 and usually omitted in expanded form), and

(9 × 1) for the ones place.

The expression that represents 13,809 in expanded form is therefore 10,000 + 3,000 + 800 + 9, which corresponds to option 'D'.

Answer:

The answer is 5,650
