A cheetah runs at a speed of 54 miles for every hour. If the distance traveled, in miles, is d and time, in hours, is t, which equation shows the relationship between d and t?
A.) d = 54t
B.) t = 54d
C.) d = 54 + t
D.) t = 54 + d
you would multiply the number of hours (t) by the speed (54) to find the distance (d)
so A) d=54t

How fast was Matt driving if he drove 415 miles in 7 hours?
The speed of Matt nearest to tenth place will be 59.3 miles per hour.
What is speed?Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Matt drove 415 miles in 7 hours. Then the speed of Matt is calculated as,
Speed = 415 / 7
Simplify the equation, then we have
Speed = 59.2857 miles per hour
Speed = 59.3 miles per hour
The speed of Matt closest to the 10th spot will be 59.3 miles each hour.

For which pair of numbers is the greatest common factor 8
given that there are eight ounces in a cup and four cups in a quart, which quantity below is equal to 128 ounces
256 ounces 64 ounces 18 cups 4 quarts
Answer:
4 quarts i had this question on a test and got it right
Step-by-step explanation:
128 ounces is equal to 4 quarts.
To solve this, we need to convert the amount given in ounces to quarts.
Step-by-Step Solution:
There are 8 ounces in a cup.There are 4 cups in a quart.Therefore, there are 8 ounces/cup × 4 cups/quart = 32 ounces in a quart.To find out how many quarts are in 128 ounces, divide 128 by 32: 128 ounces / 32 ounces per quart = 4 quarts.So, the quantity equal to 128 ounces is 4 quarts.
The other options: 256 ounces and 64 ounces are obviously not equal to 128 ounces since 256≠ 128≠ 64
and, 18 cups =18×8= 144 ounces ≠ 128 ounces.
the lines shown below are perpendicular. if the green line has a slope of 1/7, what is the slope of the red line?
Answer: it's -7
Step-by-step explanation:
Answer:
Therefore, the slope of the red line must be -7
Step-by-step explanation:
If the two lines are said to be perpendicular each other, then the multiplicative of their slope is -1.
Let "m1" be the slope a line and "m2" be the slope of the perpendicular line.
So, m1*m2 = -1
Here, let's take "m1" be the slope of the green line and "m2" be the slope of the red line.
They said to be perpendicular to each other.
So, m1*m2 = -1
Given: m1 = 1/7
NOw plug in m1 = 1/7 in the above statement, we get
1/7 *m2 = -1
Let's find the value of m2, multiply both sides by the reciprocal of 1/7
The reciprocal of 1/7 is 7.
7*1/7*m2 = -1*7
7/7.m2 = -7
m2 = -7
Therefore, the slope of the red line must be -7

b. 0 and 2
c. 0
d. 3
HURRY IM BEING TIMED!!
Answer:
Step-by-step explanation:
Given: –x² + 2x + 3 = x² – 2x + 3 .
To find: What are the solution(s) .
Solution: we have given that
–x² + 2x + 3 = x² – 2x + 3 .
On subtracting both side by x² .
-2x² + 2x + 3 = x² - x² - 2x + 3
-2x² + 2x + 3 = -2x +3
On Addition both side by 2x .
-2x² + 2x + 2x + 3 =-2x +2x +3
-2x² + 4x + 3 = 3
On subtracting both side by -3 .
-2x² + 4x + 3 -3 = 3 - 3
-2x² + 4x = 0
Taking common 2x .
2x (- x +2 ) =0 .
On grouping .
2x= 0
so x= 0
Now , -x +2 =0 .
-x = -2 .
On dividing by -1
x= 2
Therefore , option B is 0 and 2 .

Holly earns $30 for babysitting 5 hours. She earns $28 when she does chores for 4 hours. Which compares the unit rates?
The rate of earning money for both activities will be calculated by dividing the amount earned by the total time spent for each of the activity.
Babysitting: rate = ($30 / 5 hours ) = $6 / hour
Doing chores: rate = ($28 / 4 hours) = $7 / hour
Thus, Holly is able to earn money faster when doing the chores compared to when she do the babysitting if she work for the same amount of time for each.
Answer:
The unit rate for doing chores is $1 more than the unit rate for babysitting.
Step-by-step explanation:
30 divided by 5=6 So that means it was six dollars for babysitting.
28 divided by four=7 So that means it was seven dollars for babysitting.
(1-sec x)/(1-cos x) = -sec x
I got up to this:
(cos x - 1)/ (cos x(1 - cos x)
Can you help me verify the following identity?
We are given the trigonometric equation:
(1 - sec x) / (1 - cos x) = - sec x
Since the left side has more terms, then let us work on that side to make it exactly like the right side.
We know that sec = 1 / cos, therefore:
(1 – 1 / cos x) / (1 – cos x) = - sec x
[(cos x – 1) / cos x] / (1 – cos x) = - sec x
[- (1 – cos x) / cos x] / (1 – cos x) = - sec x
Cancelling out the term (1 – cos x):
- 1 / cos x = - sec x
- sec x = - sec x

During low tide, the beachfront in some places is about 350 from the ocean to the homes . High tide can change the width of a beach at a rate of -17 feet each hour . It takes 6 hours for the ocean to move from low to high tide . What is the change in the width of the beachfront from low to high tide ?
the change in width would be -17 * 6 = -102 feet
distance from the ocean to the houses would be 350-102= 248 feet
Write a conjecture for the pattern of the sequence
To conjecture a sequence, one must identify and extend the observable pattern, much like the quark hypothesis predicted unseen particles, or like recognizing the vowel sounds in specific linguistic patterns.
Explanation:In mathematics, creating a conjecture for a sequence involves analyzing the given numbers or patterns and predicting the next element based on the identified pattern. The process comparable to what the developers of the quark hypothesis did, working to predict unknown elements based on established patterns, can aid us in formulating a conjecture for the sequence in question.
For instance, if we refer to the resonance frequencies of a closed tube which form a pattern represented by the formula An = L / (4n) where n is an odd number, we can conjecture that the next frequency in the sequence would be determined by the next odd integer following the last one used.
Similarly, the binomial theorem expansion shows a pattern of coefficients that can be used to conjecture future terms in a binomial expansion. Analyzing patterns like VCC and VCle that determine whether the vowel sound should be long or short in English offer a linguistic parallel to mathematical pattern predictions.
To create a conjecture for a sequence, examine the values and look for a consistent relationship or rule. An example is adding 3 to the previous term in the sequence.
Explanation:A conjecture for the pattern of a sequence can be created by examining the values in the sequence and looking for a consistent relationship or rule. For example, if the sequence is 1, 4, 7, 10, 13, the conjecture may be that each term is obtained by adding 3 to the previous term. This can be represented mathematically as An = A(n-1) + 3, where An represents the nth term in the sequence.

or
[tex]8+12i[/tex]
Therefore, the correct solution of [tex](11+2i)-(3-10i)[/tex] = [tex]8+12i[/tex]

Which of the following formulas correctly solves for C?
A) C = 5F − 32 over 9
B) C = 5 F over 9 − 32
C) C = 9 over 5 (F − 32)
D) C = 5 over 9 (F − 32)
it is the last option C=5/9(F-32)
Answer:
option (D) is correct.
formula that solves for C is [tex]C=\frac{5(F-32)}{9}[/tex]
Step-by-step explanation:
Given : the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit, F as , [tex]F=\frac{9}{5}C+32[/tex]
We have to find the correct formula that solve for C,
Consider the given formula,
[tex]F=\frac{9}{5}C+32[/tex]
We have to find formula for C,
Thus, first subtract 32 both side, we get,
[tex]F-32=\frac{9}{5}C[/tex]
Now, multiply 5 both side, we get,
[tex]5(F-32)={9}C[/tex]
Now , divide both side by 9, we get,
[tex]\frac{5(F-32)}{9}=C[/tex]
Thus, formula that solves for C is [tex]C=\frac{5(F-32)}{9}[/tex]
Thus, option (D) is correct.
