Answer:
1:36
Step-by-step explanation:
Length:
6 inches : 18 feet
1 ft = 12 inches
6 inches = 6/12 = 0.5 ft
Length:
0.5 ft : 18 ft
then. rhe scale is:
1: 36
Determine if the sequence is arithmetic.If it is find the common difference, the 52nd term 38,47,56,65
Answer:
497
Step-by-step explanation:
Since if we take the difference between each number i.e.
47 - 38 = 9
56 - 47 = 9
65 - 56 = 9
As the difference is same that means it is a arithmetic sequence
Now
The 52nd term is
a(n) = a +(n-1)d
a(52) = 38 + (52 - 1) (9)
a(52)= 38 + 51 (9)
= 38 + 459
= 497
if your friend said that his toy can accelarate uniformly at 1.5m/s²,what is its initial speed if you record its finalspeed as7.5m/s after 5.0s running?
[tex]a = \frac{vf - vi}{t} [/tex]
[tex]1.5 = \frac{7.5 - vi}{5.0} [/tex]
[tex]1.5(5.0) = \frac{7.5 - vi}{5.0} (5.0)[/tex]
[tex]7.5 = 7.5 - vi[/tex]
[tex]7.5 - 7.5 = 7.5 - 7.5 - vi[/tex]
[tex]0 = vi[/tex]
The car's initial speed is 0 m/s
//
[tex]a = \frac{7.5 - 0}{5} [/tex]
[tex]a = 1.5 [/tex]

It takes 90 minutes to vacuum 30 vehicles. At this rate, how many minutes does it take to vacuum 7 vehicles?
Answer: 21.
Step-by-step explanation: If you do '90 x 7' you get 630. With this, you will want to divide 630 by 30. So to simplify this, '(90 x 7) ÷ 30 = 21'

Lin runs 8 laps around a track in 26 minutes.
How many minutes and seconds?
Answer:
3 minutes and 15 seconds per lap.
Step-by-step explanation:
26 ÷ 8 = 3.25
Multiply 3.25 times 60 to get the amount in seconds.
3.25 x 60 = 195
Then, subtract 60 from 195 until you can't subtract 60 anymore.
195 - 60 = 135
135 - 60 = 75
75 - 60 = 15
Add the number of times 60 was subtracted.
60 = 1 minute
So 1 + 1 + 1= 3 minutes.
Then, the 15 left over from 195 after 60 was subtracted from it three times is the amount of seconds.
3 minutes and 15 seconds per lap.

Answer: the answer is $60

A complex number of the form z = a + bi has an absolute value of 4.00. What could the values of a and b be?
a = 1.6, b = 2.3
a = 1.6, b = 2.5
a = 1.9, b = 2.1
a = 2.1, b = 3.4
Answer:
According to the question z must be equal to 4. So value of a+b=z or a+b=4
Lets try each of the options
A) a+b
1.6+2.3=3.9 which is not equal to 4
So option a is not the asnwer.
B) a+b = 1.6+2.5= 4.1 which is not equal to 4
C) a+b= 1.9+2.1= 4.00 which is equal to 4
D) a+b= 2.1+3.4= 5.5 which is not eqaul to 4
Thus, we have OPTION C AS THE CORRECT ANSWER
Answer:
It's NOT C, it's D!

Ok ok, Jonathan is making his favorite pasta dish. His mom ate 2/7 of the pasta, and his brother ate 1/6 of the pasta. How much did they eat in all?
Answer:
It is 0.4524 rounded simply you can say 0.45
Step-by-step explanation:
if you multiply 2/7 by 6 which is 12/42 and 1/6 times 7 which is 7/42 and add both fractions you will get 19/42 which is 0.45 you can either say the answer is 0.45 or 19/42.
Answer:
19/42
Step-by-step explanation:
The first thing you need to know is that we are adding because it says "How much did they eat in all?" Then, need to write down the common denominator of both 7 an 6. That is, 42. Now you have, 2/7+1/6= ?/42. Now you need to find out what the value of the numerator. We have to multiply 2 and 6 together, we will get 12. Then we got to do the same thing with 1x7, that will be 7.
12+7=19
Remember ?/42 --- that will be now 19/42
19/42 can not be further simplified.

Answer: 3/10x
Step-by-step explanation:
(-4,-2) ( 6,1 )
The points are given by the graph and can be used to find the slope
using the slope formula
y2-y1 over
x2-x1
-2-1
-4-6 = 3/10
The result can't be simplified so
the slope is 3/10x

Which of the following is an arithmetic sequence with common difference –5?
8, 3, –2, –7, . . .
B)
0, 5, 10, 15, . . .
C)
5, 25, 125, 625, . . .
D)
5, –25, 125, –625, . . .
Answer:
Option A i.e. 8, 3, -2, -7, ... is correct.
Step-by-step explanation:
Let us check the sequence given in option A
[tex]8, 3, -2, -7, . . .[/tex]
An arithmetic sequence has a constant difference '[tex]d[/tex]' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
determine the differences of all the adjacent terms of Arithmetic sequence
[tex]3-8=-5,\:\quad \:-2-3=-5,\:\quad \:-7-\left(-2\right)=-5[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=-5[/tex]
Therefore, we conclude that the arithmetic sequence 8, 3, -2, -7, ... has a common difference -5.
Hence, option A i.e. 8, 3, -2, -7, ... is correct.
Answer:
8, 3, –2, –7, . . .

Rearrange the equation so m is the independent variable. 7m + 2 = 7n − 5 , n =
Answer:
n=m+1
Step-by-step explanation:
7m+2=7n-5
add 5 to each side
7m+7=7n or 7n=7(m+1)
divide both sides by 7
n=m+1
Answer:
We have that 7m + 2 = 7n - 5
If we want to get n, you can use operations in both sides of the equation to make n the independent variable.
First, from 7m + 2 = 7n - 5, we can sum to both sides 5
7m + 2 + 5 = 7n - 5 + 5
7m + 7 = 7n
Now, we can devide both sides by 7:
(7m+7) /7 = 7n/7
7m/7 + 7/7 = n
m + 1 = n
Jen butler has been pricing speed pass train fares for a group trip to New York. Three adults and four children must pay $97. two adults and three children must pay $69. find the price of the adults ticket and the price of the child’s ticket.
Answer:
The adult's ticket cost $15 and the child's ticket cost $13
Step-by-step explanation:
System of Equations
Let's call:
x = price of the adult's ticket
y = price of the child's ticket
Three adults and four children must pay $97, thus:
3x + 4y = 97 [1]
Two adults and three children must pay $69, thus:
2x + 3y = 69 [2]
Multiplying [1] by -2 and [2] by 3:
-6x - 8y = -194 [3]
6x + 9y = 207 [4]
Adding [3] and [4] (the x's cancel out):
-8y + 9y = 13
y = 13
From [1]
3x + 4*13 = 97
3x + 52 = 97
Subtracting 52:
3x = 45
Dividing by 3:
x = 15
The adult's ticket cost $15 and the child's ticket cost $13
