Find the difference between -4 and 2

Answer:

20 years

Step-by-step explanation:

Using the formula; A = P(1 + r)^t

We can plug in the known to find t

400 = 220(1.03)^t

then solve for t;

1.818 = 1.03^t

Introducing In

In 1.818 = t × In (1.03)

t = 20.225  

t = 20 years to the nearest year

Answer:

rate change: -8

Equation: y = 232 -8x

After 5 hours: 192

Step-by-step explanation:

8 are destroyed every hour, so there are 8 less every hour, so the rate of change is -8

It starts with 232 and loses 8 per hour, so the formula is

y = 232 - 8x

After 5 hours:

y = 232 - 8(5)

    y = 232 - 40

         y = 192

Answer:

Step-by-step explanation:

The rate of change in this case is -8, since the amount is decreasing.

The equation is:

y=232-8x.

After 5 hours, he will have 192 rews.

Answer:

w=3

Step-by-step explanation:

The area of the triangle is given by

A = 1/2 bh

the base is 5 and the height is 3

A = 1/2 (3) * 5 = 15/2  units ^2

The area of a rectangle is

A = l*w

A = 5w

The area of the triangle = 1/2 the area of the rectangle

15/2 = 1/2 *5w

15/2 = 5/2 w

Multiply each side by 2/5 to isolate w

2/5 * 15/2 = 2/5 *5/2 w

3 =w

Final answer:

The area of the triangle is 7.5 units and the width of the rectangle is 3 units.

Explanation:

The area of a triangle can be calculated using the formula A = (base * height) / 2. In this case, the base of the triangle is given as 5 units and the height is given as 3 units.

So, the area of the triangle is A = (5 * 3) / 2 = 15 / 2 = 7.5 units.

The area of the rectangle is given as 5 units long and units wide. Since the area of the triangle is equal to half of the area of the rectangle, we can set up the equation 7.5 = (5 * width) / 2 and solve for the width.

By multiplying both sides of the equation by 2 and then dividing by 5, we get width = (7.5 * 2) / 5 = 15 / 5 = 3 units. Therefore, the width of the rectangle is 3 units.

Step-by-step explanation:

Answer: The sales tax rate is 5%.

Step-by-step explanation: In order to calculate the sales tax rate you need to divide the amount of sales tax by the amount of the purchase. In this case you divide .20 by $4.00. .2 / 4 = .05 = 5% sales tax rate

The sales tax rate for a pack of cinnamon-scented pencils that sells for $4.00 and totals $4.20 is 5%.

To calculate the sales tax rate for a pack of cinnamon-scented pencils that sells for $4.00 and has a total cost of $4.20 including tax, you first need to find the amount of sales tax paid. The sales tax paid is the difference between the total cost and the sale price, which is

$4.20 - $4.00 = $0.20.

Next, you convert the sales tax amount to the sales tax rate by dividing the tax amount by the original price and then multiplying by 100 to get a percentage. Therefore, the sales tax rate is

($0.20 / $4.00) x 100, which equals 5%. The packed pencils had a 5% sales tax added to the original price.

The perimeter is 38.25 units

Step-by-step explanation:

The perimeter of the tra-pezoid is the distance around it.

The length of the bases can be found using the absolute value method.

|RS|=|20-14|=6 units.

|TQ|=|22-8|=14

Recall the distance formula;

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We use the distance to find the non parallel sides.

and

[tex]|QR|=\sqrt{(8-14)^2+(16-8)^2} =10[/tex] units.

The perimeter of the tra-pezoid is

Answer:

B. 14 = 125p

Step-by-step explanation:

The correct equation to find what percent 14 is of 125 is 14 = 125p. This equation is solved by dividing both sides by 125. The solution, 0.112 or 11.2%, shows that 14 is 11.2% of 125.

The subject of the question is Mathematics. The question is, 'Which equation can be used to find what percent 14 is of 125?' The correct equation to solve this is: 14 = 125p. The reason for that is because the problem is asking what percent (represented by p) 14 is of 125. So, you want to solve for p. To do so, you would divide both sides of the equation by 125. This would give you p = 0.112, or 11.2%. This means that 14 is 11.2% of 125.

Step-by-step explanation:

115+10x = y

After 7 trips to the fair, Erin has 185 stamps in her collection according to to the equation y = 115 + 10x.

To find out how many stamps Erin has after 7 trips to to the fair, we can use the given equation:

where:

- [tex]\( y \)[/tex] represents the number of stamps in Erin's collection.

- [tex]\( x \)[/tex] represents the number of times Erin has been to to the stamp fair.

Substituting [tex]\( x = 7 \)[/tex] into the equation, we get:

This is a maths problem involving the Pythagorean theorem, which involves calculating the hypotenuse of a right triangle. The squirrel, living in a tree 12 meters high and needing to glide to an acorn 16 meters away, will need to glide a distance of 20 meters.

This question is essentially asking you to calculate the hypotenuse in a right triangle, and the formula for this is rooted in the Pythagorean theorem. You're given the height of the tree (12 meters), which we can call 'a', and the distance from the base of the tree to the acorn (16 meters), which we can designate as 'b'.

The Pythagorean theorem goes as follows: a squared + b squared = c squared, where 'c' is the hypotenuse of the triangle, or in this case, the distance the flying squirrel needs to glide. So, we can plug in the numbers we have: (12²) + (16²) = c². This simplifies to 144 + 256 = c², or 400 = c².

To solve for 'c', we take the square root of both sides, and find that c = 20. Thus, the flying squirrel needs to glide 20 meters to reach the acorn.

The flying squirrel will have to glide 20 meters to reach the fallen acorn.

To find out how far the flying squirrel will have to glide to reach the fallen acorn, we can use the Pythagorean theorem because the squirrel will glide in a straight line from the tree to the acorn.

Let's denote the distance the squirrel glides as ( x ). According to the Pythagorean theorem, in a right triangle, the square of the hypotenuse (the distance the squirrel glides) is equal to the sum of the squares of the other two sides (the height of the tree and the horizontal distance to the acorn).

The given information:

- Height of the tree  =  12 meters

- Horizontal distance to the acorn  =  16 meters

Using the Pythagorean theorem, we have:

[tex]\[x^2 = (\text{Height})^2 + (\text{Distance to acorn})^2\]\[x^2 = 12^2 + 16^2\]\[x^2 = 144 + 256\]\[x^2 = 400\][/tex]

Taking the square root of both sides:

[tex]\[x = \sqrt{400}\]\[x = 20\][/tex]

So, the flying squirrel will have to glide 20 meters to reach the fallen acorn.

Answer:

SA = 124 cm²

Step-by-step explanation:

The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.  

93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area

The surface area of the tetrahedron is 124 square centimeters.

Let's denote the surface area of one equilateral triangle as A The total surface area of the tetrahedron, which includes all four faces, is then  4A.

 Given that the lateral surface area (which is three faces) is 93 square centimeters, we can write:

 3A = 93

To find the area of one face (A), we divide both sides by 3:

[tex]\[ A = \frac{93}{3} = 31 \][/tex]

Now, to find the total surface area of the tetrahedron, we multiply the area of one face by 4:

[tex]\[ \text{Total Surface Area} = 4A = 4 \times 31 = 124 \][/tex]

Therefore, the surface area of the tetrahedron is 124 square centimeters.
