Answer:

12 miles per hour

Step-by-step explanation:

The math formula says that 1 foot per hour is equal to 1/5280 mile per hour.

Lets convert 15 feet per second to per hour.

15 * 60 * 60 =54,000 feet per hour.

Now let's use the equation to convert the feet per hour into miles per hour.

54,000/5,280 = 10.2 mph

12 miles per hour is faster.

Answer: True

Step-by-Step Explanation:

=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3

Substitute values of ‘x’ and ‘y’ in Eq. 1 :-

=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS

Therefore, it is a Solution.

Answer:

f(x) = (x + 3)

Step-by-step explanation:

when it's in the parentheses, it's the opposite so in this if it's saying 3 units to the left, it would be subtracting or negative so to make it the opposite u do x + 3 in parentheses

i think... i don't remember tbh

The total surface area of the solid is 4651 sq cm

Step-by-step explanation:

Given,

The diameter of the base = 16 cm

Length of the cylindrical part (h) = 75 cm

The height of the solid = 90 cm

So, the radius of the base(r) = $\frac{16}{2}$ cm = 8 cm

The height of the cone = 90 - 75 cm = 15 cm

The slanting height(l) of the cone = $\sqrt{15^{2}+8^{2} }$ cm = 17 cm [ by Pythagoras theorem]

To find the total surface area of the solid

The solid consists of two separate solids that are a cylinder and a cone.

So, total surface area (TSA) of the solid = TSA of cylinder + TSA of cone

To find the TSA pf cylinder

Formula

TSA of cylinder = 2πrh +2πr

=2πr(r+h)

=2 × $\frac{22}{7}$ ×8×(8+75) sq cm

= 4173.7 sq cm (approx)

Again,

To find the TSA pf cone

Formula

TSA of cone = πrl +2πr

=πr(l+2) sq cm

= $\frac{22}{7}$ ×8×(17+2) sq cm

= 477.7 sq cm (approx)

Hence, total surface area (TSA) of the solid = 4173.7 sq cm + 477.7 sq cm

= 4651.4 sq cm
