Answer:
A. 119 feet
Step-by-step explanation:
the height of tree right now =
17 × 8 = 136 feet
the differences = 136 -17 = 119 feet
Answer:
A. 119
Step-by-step explanation:
In 15 years, the tree grew to a height of 8 x 17 = 136 feet. Since it was planted at a height of 17 feet, the tree grew 136-17=119 feet.

If a1 = 8 and an
An-1 + 2 then find the value of a4.
9514 1404 393
Answer:
a4 = 14
Step-by-step explanation:
Use the recursive definition repeatedly.
a1 = 8
a2 = a1 +2 = 8 +2 = 10
a3 = 10 +2 = 12
a4 = 12 +2 = 14
_____
The recursive definition tells you the terms of the sequence have a common difference of 2. The explicit formula for a term of the sequence can be written as ...
an = 8 + 2(n-1)
Then a4 is ...
a4 = 8 +2(4 -1) = 8+6
a4 = 14
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
Suppose the purchase price of a dining room set is $950. If the sales tax is $47.50, what is the sales tax rate?
Answer:
5%
Step-by-step explanation:
this question is really asking what percent of 950 is 47.5?
is/of = %/100
47.5 is the 'is'
950 is the 'of'
'r' is the 'what percent'
47.5/950 = r/100
cross-multiply to get:
950r = 4750
r = 5
Answer:
5%
Step-by-step explanation:
Price x sales tax rate = sales tax
950 x sales tax rate =47.50
sales tax rate =47.50/950
sales tax rate = .05 or 5%

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.
A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange. Let B = the event of getting a blue jelly bean Let G = the event of getting a green jelly bean. Let O = the event of getting an orange jelly bean. Let P = the event of getting a purple jelly bean. Let R = the event of getting a red jelly bean. Let Y = the event of getting a yellow jelly bean. Find P(R)
Answer: [tex]\frac{11}{75}[/tex]
Step-by-step explanation:
R is the event of getting a red jelly bean. 22 out of the 150 jelly beans are red. That means it is a [tex]\frac{22}{150}[/tex] chance of getting a red jelly bean.
Simplified that is [tex]\frac{11}{75}[/tex]

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

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.
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
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

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.
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
