Answer:

B.) 9

Step-by-step explanation:

The square root of 75 is 8.660254038 (or 8.6). The 6 tells us that we need to round up to a whole number which makes it the closest to 9

Answer: C

Step-by-step explanation: The surface of the lake.

Answer:

x = 3/5

Step-by-step explanation:

5th root of Y is notated in exponential notation as Y^(1/5), which is Y to the one fifth (1/5) power.

So, the 5th root of 19^3 is (19^3)^(1/5) = 19^(3 * 1/5) = 19^(3/5), since (A^a)^b = A^(a*b).

If there's no d than I guess c, k maybe the calories of a kookie and x is the amount, 2 isn't mentioned for the question we need to answer, and 72 isn't too, 5

5 maybe the answer

Answer:

Its easier to do it on a number line but I'm going to give you the straight answer when you count from negatives to positives you go left to right -15, -14, -13, -12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1 and then always have the 0 so 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 It would be 25

Answer:

u=v-at

Step-by-step explanation:

When making something the subject of the formula, we need to get that thing on 1 side of the equation all by itself. To do this, we need to rearrange.

Because I can see that the side with my "u" has a "+at", I need to get the "+at" onto the other side of the "=", I can do this by subtracting it on both sides (because that - is the inverse of +). So I now have v-at=u. Which is the final answer.

Note: it doesn't matter which side U is on, as long as it is alone (so this equation can also be written as u=v-at.

On a budget of $150, Mrs. Jennings will only be able to take 25 kids to the museum.

Mrs. Jennings has $150 in total and has to spend it on the bus and getting the kids into the museum.

After she spends on the bus, she will be left with:

= Budget - Cost of bus

= 150 - 100

= $50

She then spends $2 per kid. The total number of kids she can bring into the museum is:

= Amount remaining/ Cost per kid

= 50 / 2

= 25 kids

In conclusion, she can only take 25 kids.

Step-by-step explanation:

the negatives cancel each other out therefore 1.02*4= 4.08

When we Evaluate. [tex]0 / -1 * 0^2 * -4[/tex] the values is 0. To evaluate the expression, follow the order of operations (PEMDAS/BODMAS):

P - Parentheses/Brackets

E - Exponents/Orders

MD - Multiplication and Division (from left to right)

AS - Addition and Subtraction (from left to right)

The expression is: [tex]0 / -1 * 0^2 * -4[/tex]

Step 1: Exponents/Orders

0^2 = 0 (Any number raised to the power of 0 is always 0).

Step 2: Division

0 / -1 = 0 (Any number divided by 0 is undefined, but in this case, it would be 0).

Step 3: Multiplication : 0 * 0 * -4 = 0

So, the final answer is 0.

The equation to represent this scenario is d(t) = -2t + 10.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

Given, Harry starts 10 miles away from home.

For each minute his distance decreases by two miles.

Assuming no. of minutes to be 't' and distance to be d(t).

∴ d(t) = -2t + 10.

Step-by-step explanation:

with the height in a right triangle, we get 3 right triangles (the original one, and the 2 on both sides of the height). all 3 of these triangles are similar to each other.

that means (among other things) the ratios of 2 sides of one triangle must be the same ratio of the corresponding sides in the other triangle.

x/64 = 36/x

x² = 36×64

x = sqrt (36×64) = 6×8 = 48

long story short, x is the geometric mean value of the segments of the Hypotenuse.

geometric mean value means the nth root of the product of n numbers.

in our case - square root out of 2 numbers (the segment lengths).

Answer:

424,752.7 cm³

Step-by-step explanation:

Since you need to convert from English units to Metric units, you can do that first.

Convert each measurement to centimeters instead of feet since your final answer is in cubic centimeters.

1 foot = 30.48 centimeters

Length = 3 ft    30.48cm

              -----  x ------------    =  91.44 cm

                1            1 ft

Width =  2 ft       30.48cm

            -------  x  -------------  =   60.96 cm

                1             1 ft

Height = 2.5 ft      30.48cm

              --------  x  ------------  =  76.2 cm

                  1            1 ft

The volume is equal to L x W x H

91.44cm x 60.96cm x 76.2cm = 424,752.7 cubic centimeters
