Ivan is on a three-day hike. The hike is 60 miles long. If he walked 15 miles on the first day and 25 miles on the second day, how many miles does he have left to walk?

Answer:

The answer is 7 ⇒ answer (C)

Step-by-step explanation:

∵ (3 + √2)(3 - √2) =

  9 - 3√2 + 3√2 - 2 = 9 - 2 = 7

∴ The answer is 7

For this case we must simplify the following expression:

[tex](3+ \sqrt {2}) (3- \sqrt {2})[/tex]

We apply distributive property:

[tex]9-3 \sqrt {2} +3 \sqrt {2} - \sqrt {2} * \sqrt {2} =[/tex]

We take into account that different signs are subtracted and the sign of the major is placed:

[tex]9 - (\sqrt {2}) ^ 2 =\\9-2 =[/tex]

We take into account that different signs are subtracted and the sign of the major is placed:

[tex]9-2=7[/tex]

So, we have:

[tex](3+ \sqrt {2}) (3- \sqrt {2}) = 7[/tex]

[tex]\large\boxed{x^2+y^2+4x-2y+1=0}[/tex]

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

The general form of an equation of a circle:

[tex]x^2+y^2+Dx+Ey+F=0[/tex]

We have the center (-2, 1). Substitute to the equation in the standard form:

[tex](x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2[/tex]

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

[tex](-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4[/tex]

Therefore we have the equation:

[tex](x+2)^2+(y-1)^2=4[/tex]

Convert to the general form.

Use [tex](a\pm b)^2=a^2\pm 2ab+b^2[/tex]

[tex](x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\qquad\text{subtract 4 from both sides}\\\\x^2+y^2+4x-2y+1=0[/tex]

Answer:

B is correct

Step-by-step explanation:

-(-x) = x, because a double negative like this equals a positive.

Equation B. is true for all values of x.

Answer:

if you mean minutes the answer is 150 seconds

Step-by-step explanation:

each minute is 60 seconds so 2 minutes is 120 and the half a minute is 30 seconds so 60+60+30=150

if you ment hours then the answer is 9000 seconds

2 and a half days= 216000

Answer: Depends

Step-by-step explanation: For minutes, it's 150 seconds. Every minute is 60 seconds, and 2.5*60 = 150. If you mean hours, then it's 9000 seconds. That equation would be [tex](60*60)*2.5[/tex]. If you mean milliseconds, then it would be 0.0025 seconds.

Edge 2021-2022

The original blanket was a square with side 31 inches both in length and width. After adding 1 foot to one side, and subtracting 4 inches from the other, new dimensions are 43 inches and 27 inches, respectively. Thus, the new area of the blanket is 1161 square inches.

To solve this problem, we first need to note that the area of a rectangle (which our blanket has now become) is the product of its length and width. Since Kiara's blanket was originally a square before she added 1 foot to one side (12 inches) and subtracted 4 inches from the adjacent side, the original side length was the square root of the given area, i.e., √960 inch² = 31 inch. So, one dimension after alteration is 31 inches + 12 inches = 43 inches, and the other (after cutting) is 31 inches - 4 inches = 27 inches. Therefore, the new area of the blanket is 43 inches x 27 inches which equals 1161 square inches.

The area​ of the original blanket is 784² square inches

Let's denote the side length of the original square blanket as 'x' inches.

After adding 1 foot (12 inches) to one side, the length of that side becomes x + 12 inches.

After cutting 4 inches off from an adjacent side, the length of that side becomes x - 4 inches.

We are given that the area of the resulting blanket is 960 square inches. This can be expressed as:

(x + 12)(x - 4) = 960

Expanding the left side of the equation, we get:

x^2 + 8x - 48 = 960

Adding 48 to both sides of the equation, we get:

x^2 + 8x = 1008

Dividing both sides of the equation by x, we get:

x + 8 = 1008/x

Solving for x using a quadratic equation solver or by trying out different values, we find that x ≈ 28.

Therefore, the area of the original square blanket is:

x^2 = 28^2 = 784 square inches

Answer:

D) d,c,a,b

Step-by-step explanation:

To arrange the fractions in the order requested we have to express them to a common denominator . This is done by finding the Least common multiple of the denominators. Thus, the fractions,7/3, 8/2, 2/1,6/5, the L.C.M of the denominators is 30 thus lets divide the L.C.M by the denominator of each number then multiply with the numerator.

7/3=70/30

8/2=120/30

2/1=60/30

6/5=36/30

thus from the least  to the largest we arrange them as follows 6/5, 2/1, 7/3 then 8/2

The product of −8/5, −3/2, and −10 is −24. The calculation involves two steps: first multiplying the two negative fractions, which results in a positive product, and then multiplying that result by a negative integer, resulting in a negative final product.

To find the product of −8/5, −3/2, and −10, you multiply the three numbers together.

Remember that when you multiply two negative numbers, the result is positive, and when you multiply a negative number by a positive number, the result is negative.

Multiplying −8/5 and −3/2 first gives:

(−8/5) × (−3/2) = 24/10 = 2.4, and since both numbers are negative, the result is positive.

Now, multiply the result by −10:

2.4 × (−10) = −24. Since you are now multiplying a positive number by a negative number, the result is negative.

Therefore, −8/5 multiplied by −3/2 and then by −10 results in −24.

The product is [tex]\(-24\)[/tex].

To find the product of the given expressions, you simply multiply the numbers together.

[tex]\[\left(-\frac{8}{5}\right) \cdot \left(-\frac{3}{2}\right) \cdot \left(-10\right)\][/tex]

First, multiply the fractions:

[tex]\[\left(-\frac{8}{5}\right) \cdot \left(-\frac{3}{2}\right) = \frac{24}{10}\][/tex]

Now, multiply the result by the remaining number:

[tex]\[\frac{24}{10} \cdot (-10) = -24\][/tex]

Answer:

300

Step-by-step explanation:

A number cube has total six possible outcomes:

1, 2, 3, 4, 5 and 6

Probability of the occurrence of each side is: 1/6

From the possible outcomes, the even number are 2,4,6

Therefore the probability of the occurrence of an even number is:

1/6 + 1/6 + 1/6

=> 3/6

=> 1/2

1/2 probability shows that if a number cube is rolled 'n' times, (1/2)*n number of chances are it is an even number.

So the expectation of rolling an even number with 600 trials is:

(1/2)*600

#1) 108.375 cubic inches

Step-by-step explanation:

For a pan of dimensions 8.5 in x 8.5 in, with height 2.25 in:

If cornbread fills to .75 in from the top, the height of cornbread is 2.25-.75 = 1.5 in

Volume = length*width*height (for rectangular prisms)

So Volume of corn bread = 1.5*8.5^2 = 108.375 cubic inches

For the second part, it is a poorly worded question. Squares are two dimensional, so it realistically cannot be cut into squares. If the question means cubes, the answer is yes to a certain extent. Since the height is exactly 1.5 in, and the pan is 8.5 in x 8.5 in, Marita can cut the cornbread into squares, but she cannot cut all of it into squares since 8.5/1.5 is not a whole number.

Answer

5/8 students buy orange juice

To find the fraction of students who buy orange juice, we first find the fraction of students who buy juice and then multiply it by the fraction that buy orange juice.

To find the fraction of students who buy orange juice, we first need to determine the fraction of students who buy juice. Since 5/6 of students buy juice, this means that 5/6 of the total number of students buy juice.

Next, we need to determine the fraction of students who buy orange juice out of those who buy juice. Since 3/4 of the students who buy juice buy orange juice, this means that 3/4 * 5/6 of the total number of students buy orange juice.

To find the final fraction, we multiply the two fractions:

3/4 * 5/6 = (3 * 5) / (4 * 6) = 15 / 24 = 5/8

Therefore, the fraction of students who buy orange juice is 5/8.

Answer:

c: 1,335 yd³

Step-by-step explanation:

The formula for volume of a cylinder is V = πr²h  where r is the radius of the base circle, and h is the height of the cylinder

We are given r = 5, and h = 17.  Plug them in and solve for V...

V = π(5²)(17)

    V = π(25)(17)

          V = 425π

              V = 425(3.14) = 1,334.5 yd³,

so 1,335 yd³ rounded to the nearest cubic yard
