Find the first four terms of the sequence given by the following
9514 1404 393
Answer:
59, 56, 53, 50
Step-by-step explanation:
Use n = 1 through 4 and evaluate.
a1 = 59 -3(0) = 59
a2 = 59 -3(1) = 56
a3 = 59 -3(2) = 53
a4 = 59 -3(3) = 50
The first four terms are 59, 56, 53, 50.

Samuel made a list of his test scores: 88, 100, 92, 80, 85, 94, and 90. What is the lowest test score he can get on his next test to have mean score of 90?
Answer:
he needs to get a 91 to have a mean score of 90
Step-by-step explanation:
add up all the known scores to get 629
let 's' = lowest test score
(629 + s) ÷ 8 = 90 [we divide by 8 because there are 7 known and 1 unknown score)
cross-multiply to get:
629 + s = 720
s = 720-629
s = 91

how can i get a cientific form number
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
Scientific notation is helpful when dealing with really large numbers with a lot of zeroes because you can express them with smaller numbers, and it looks a lot more simple. It's just a different way to express numbers.
Here's an example : Let's say someone asked me to put the number
650,000,000 into scientific notation.
That would be 6.5 ✕ 10^8

A number, one-fourth of that number, and one-third of that number are added. The result is 38. What is the original number?
Answer:
24
Step-by-step explanation:
Let 12x represent the original number.
One fourth of that number can be represented by 3x, and one third of the number can be represented by 4x.
Create an equation that sets this equal to 38, and solve for x:
12x + 3x + 4x = 38
19x = 38
x = 2
The original number is represented by 12x, so plug in 2 as x:
12(2)
= 24
So, the original number is 24.
the scale is 7 millimeters = 1 meter. what is the scale factor?

50% of a number is 32
what is the number
Answer:
64
Step-by-step explanation:
Half (50%) of 64 would be 32
Answer:
64
Step-by-step explanation:
let the number be x
according to the question ,
50 % of x = 32
50/100 * x = 32
50x = 32 *100
x = 3200/50
x = 64
therefore a number is 64

In the past 100 years, scientists measured the movement of the continents to be 190.5 centimeters. If the continents moved the same amount each year, how much did the continents move in one year?
Answer:
The continents moved by 1.905 centimeters each year.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
In the past 100 years, scientists measured the movement of the continents to be 190.5 centimeters. How much it moved in a year?
100 years - 190.5 centimeters.
1 year - x centimeters
[tex]100x = 190.5[/tex]
[tex]x = \frac{190.5}{100}[/tex]
[tex]x = 1.905[/tex]
The continents moved by 1.905 centimeters each year.
Find an expression which represents the difference when (-4x – 3y) is subtracted
from (-2x – 10y) in simplest terms.
Answer: (-2x-10y)-(-4x-3y)
-2x-10y-(-4x-3y)
-2x-10y+4x+3y
-2x+4x-10y+3y
-2x+4x-10y+3
Answer =2x-7y
Step-by-step explanation:
What is the value of y?
Answer:
y= 40
Step-by-step explanation:
The sum of the angle of a triangle is 180
2y+ 50 + y+10 = 180
Combine like terms
3y + 60 =180
Subtract 60 from each side
3y +60-60 = 180-60
3y = 120
Divide by 3
3y/3 = 120/3
y= 40
Answer:
y=40
Step-by-step explanation:
2y+ y+10+50=180
3y+60=180
3y=180-60
3y=12O
y=120/3
y=40

What is the cardinality of the set {4,9,12,19,26}
Answer:
5
Step-by-step explanation:
Given the set {4,9,12,19,26}
The cardinality of any given set is the measure of the size of the set. Hence, cardinality if a set simply means the size of a set, which is obtained by counting the number of distinct element in the set.
The set Given above, the number of distinct element in the set is 5 ; Hence, the cardinality of the set is 5
16. Find the value of X (In the picture) (giving points to best answer/brainlest)
Answer:
x = 46°
Step-by-step explanation:
the obtuse triangle is isosceles so the angle adjacent to ∠x is 22°
therefore, ∠x = 180-(90+22+22) = 46
