You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.

90/60 = 1.5

90 minutes = 1.5 hours

speed = distance/time = (105 miles)/(1.5 hours) = 70 mph

Question 6 (1 point)
Shalnov [3]
2. Dividing exponential expression with the same base is what the left hand fractional expression is. Z^8/Z^?=z^6. Since all the bases are the same. To get the exponential power 6 on the right we subtract the denominator’s (bottom part of the fraction) exponential power (on the left) from the numerator’s (top part) exponential power.

Then, 8 - ? = 6? 2 is the only number to make the left equal the right side. This, z^8/z^2=z^6

A farmer has 64 feet of fence to enclose a rectangular vegetable garden. which dimensions would result in the biggest area for t
Blababa [14]
The dimensions that would result to maximum area will be found as follows:
let the length be x, the width will be 32-x
thus the area will be given by:
P(x)=x(32-x)=32x-x²
At maximum area:
dP'(x)=0
from the expression:
P'(x)=32-2x=0
solving for x
32=2x
x=16 inches
thus the dimensions that will result in maximum are is length=16 inches and width=16 inches

<u>Part 1</u>

By the inscribed angle theorem, arc PA measures 62 degrees.

<u>Part 2</u>

Angles inscribed in the same arc are congruent, so angle PRA measures 31 degrees.

<u>Part 3</u>

Diameters form semicircles, and the arc of a semicircle measures 180 degrees, so arc PAR measures 180 degrees.

<u>Part 4</u>

Subtracting arc PA from arc PAR, we get arc AR measures 118 degrees.

If I have something like -x^2 when I plug the number in, will it be positive or negative and why
MrRissso [65]
The order of operations tells you exponentiation is done before multiplication or addition. That is, the value of x is squared before the sign is applied.

Your result will be negative for any non-zero value of x.

Observe the expression below and select the true statement(s).<br><br> 3y(7 + 2x) + 9xy - 10
Sedaia [141]

Answer:

The "3y" in the first term is a factor

The "9" in the second term is a coefficient

The "(7 + 2x)" in the first term is a factor

Step-by-step explanation:

Given in the question an expression

3y(7 + 2x) + 9xy - 10

  1. The coefficients are the numbers that multiply the variables, x and y.
<h3>Example</h3>

6y

6 is coefficient

    2.Constants are terms without variables

<h3>Example</h3>

 10

    3.The factors in a mathematical expression are parts of the expression that are connected with multiplication.

<h3> Example</h3>

(4x+1)(3x+7)

(4x+1) and (3x+7) both are factors
