Kim Kardashian has 4 children. North West is 5 years older than Chicago West. Psalm West is a year younger than Chicago West. Saint is twice as old as Chicago. If the sum of their ages is 14, how old is North West? Write an equation
Answer: North West would be 7 years old!
Explanation: How old is North West? This is the equation:
Their ages are...
Psalm West is 1 year oldChicago West is 2 years oldSaint is 4 years old1 + 2 + 4 = x
1 + 2 + 4 = 7
If the sum of their ages is 14 so...
14 (sum of ages) - 7 (total numbers of combined 3 West siblings)
14 - 7 = 7
The perimeter of a football field is 920 feet. The width is 60 feet more than one-third of the length. What are the dimensions of a football field?
Given:
Perimeter of a football field = 920 feet.
The width is 60 feet more than one-third of the length.
To find:
The dimensions of a football field.
Solution:
Let the length of the field be x.
Then, width = [tex]\dfrac{1}{3}x+60[/tex]
We know that,
[tex]Perimeter = 2( length + width)[/tex]
[tex]920 = 2(x+\dfrac{1}{3}x+60)[/tex]
[tex]920 = 2(\dfrac{4}{3}x+60)[/tex]
[tex]920 =\dfrac{8}{3}x+120[/tex]
Subtract both sides by 120.
[tex]920-120 =\dfrac{8}{3}x+120-120[/tex]
[tex]800 =\dfrac{8}{3}x[/tex]
Multiply both sides by 3.
[tex]2400 =8x[/tex]
Divide both sides by 8.
[tex]300 =x[/tex]
Now,
[tex]Length = 300\text{ feet}[/tex]
[tex]Width=\dfrac{1}{3}(300)+60[/tex]
[tex]Width=100+60[/tex]
[tex]Width=160\text{ feet}[/tex]
Therefore, the length and width of the football field are 300 feet and 160 feet respectively.
Angle B and angle C are supplementary If the measure of angle B is 14 times the measure of angle C, what is the difference between
the angles measures
Pls help asap
Answer:
The difference between the angle measure is 152 degrees
Step-by-step explanation:
Supplementary angles are angles that add up to 180
So if one angle is x in this case, the other will be 14x
Adding both ;
x + 14x = 180
15x = 180
x = 180/15
x = 12
The other angle is 14 * 12 = 168
The difference between the two will be;
168-12 = 156
Here are the first four terms of an arithmetic sequence. 3 10 17 24 Find, in terms of n, an expression for the nth term of this arithmetic sequence.
Answer:
[tex]a_{n}[/tex] = 7n - 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 10 - 3 = 7 , thus
[tex]a_{n}[/tex] = 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4

Answer:
The measurement of largest angle is 83°
Step-by-step explanation:
Given angles are:
(2x+1)° , (x+15)° and x°
The sum of internal angles of a triangle is 180°
We will use this sum to find the value of x first
[tex](2x+1)+(x+15)+x = 180\\2x+1+x+15+x = 180\\4x+16 = 180\\4x = 180-16\\4x = 164\\\frac{4x}{4} = \frac{164}{4}\\x = 41[/tex]
Now the measurement of angles are:
x = 41
[tex]2x+1 = 2(41)+1 = 82+1 =83\\x+15 = 41+15 = 56[/tex]
Hence,
The measurement of largest angle is 83°
Solve for x. 4x-5=9+20
Answer:
x = 8.5
Step-by-step explanation:
4x-5=9+20 (evaluate right side)
4x - 5 = 29 (add 5 to both sides)
4x = 29 + 5
4x = 34 (divide both sides by 4)
x = 34/4
x = 8.5
Answer:
Today : Saturday, 07 November 2020
Hour: 14.28 WIB (Indonesia)
_______________________________
4x - 5 = 9 + 20
= 4x - 5 = 29
= 4x = 29 + 5
= 4x = 34
= x = 34/4
= x = 17/2
= x = 8 1/2

Stan has $95. He wants to buy as many movies as he can. All movies are originally
$12.00 and are on sale for 10% off. Tax is 5%
Answer:
Step-by-step explanation:
Each movie is $12.00. 10% off of 12% is 12-1.2 = 10.8
The final amount spent is 5%, that means we can multiply the end amount spend by 1.05
The maximum Stan can spend is $95
[tex](10.8m)*1.05\leq 95\\(10.8m)\leq 90.4762\\m \leq \frac{90.4762}{10.8}\\m\leq 8.3774[/tex]
Now, you can't buy 0.3 of a movie, so the most Stan can buy is 8 movies
Lakita wants to go to trade school and study electronics for a two-year program. Her tuition and books will cost about $5,500 per year. She will also spend about $100 a month commuting from her parents’ house to school. How much will her education cost her in total?
Answer:
$13,400
Step-by-step explanation:
Given the following data;
Tuition and book per year = $5,500
Transportation per month = $100
In 2 years;
Total tuition and book = $5,500 * 2 = $11,000
Total tuition and book cost = $11,000
Transportation;
There are 12 months in a year, in 2 years = 12 * 2 = 24 months.
Thus, total on transportation = $100 * 24 = $2,400
Total transportation cost = $2,400
[tex] Overall \; cost = Total \; tuition \; and \; book \; cost + Total \; transportation \; cost[/tex]
Substituting into the above equation, we have;
Overall cost = $11,000 + $2,400
Overall cost = $13,400.
Hence, Lakita's education will cost her $13,400 in total.

Answer:
[tex]Number\ of\ Committee = 6914880\ ways[/tex]
Step-by-step explanation:
Given
Total:
[tex]Freshmen= 7\\ Sophomores = 8\\ Juniors = 8\\ Seniors = 8[/tex]
Selection
[tex]Freshmen= 2\\ Sophomores = 3\\ Juniors = 4\\ Seniors = 5[/tex]
Required
Determine the number of selection
To do this, we make use of combination formula:
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
For Freshmen, we have:
[tex]n = 7; r = 2[/tex]
[tex]^7C_2 = \frac{7!}{(7-2)!2!}[/tex]
[tex]^7C_2 = \frac{7!}{5!2!}[/tex]
[tex]^7C_2 = \frac{7 * 6 * 5!}{5! * 2 * 1}[/tex]
[tex]^7C_2 = \frac{7 * 6}{2}[/tex]
[tex]^7C_2 = \frac{42}{2}[/tex]
[tex]^7C_2 = 21[/tex]
For Sophomores, we have:
[tex]n =9;r=3[/tex]
[tex]^9C_3 = \frac{9!}{(9-3)!3!}[/tex]
[tex]^9C_3 = \frac{9!}{6!3!}[/tex]
[tex]^9C_3 = \frac{9 * 8 * 7 * 6!}{6! * 3 * 2 * 1}[/tex]
[tex]^9C_3 = \frac{9 * 8 * 7 }{6}[/tex]
[tex]^9C_3 = \frac{504}{6}[/tex]
[tex]^9C_3 = 84[/tex]
For Juniors, we have:
[tex]n = 8; r = 4[/tex]
[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]
[tex]^8C_4 = \frac{8!}{4!4!}[/tex]
[tex]^8C_4 = \frac{8 * 7 *6 * 5 * 4!}{4!*4 * 3 * 2 * 1}[/tex]
[tex]^8C_4 = \frac{8 * 7 *6 * 5}{4 * 3 * 2 * 1}[/tex]
[tex]^8C_4 = \frac{1680}{24}[/tex]
[tex]^8C_4 = 70[/tex]
For Seniors
[tex]n = 8; r = 5[/tex]
[tex]^8C_5 = \frac{8!}{(8-5)!5!}[/tex]
[tex]^8C_5 = \frac{8!}{3!5!}[/tex]
[tex]^8C_5 = \frac{8 * 7 *6 * 5!}{5! * 3 * 2 * 1}[/tex]
[tex]^8C_5 = \frac{8 * 7 *6}{3 * 2 * 1}[/tex]

Solve the equation.
y + 6 = -3y + 26
Oy= -8
O y = -5
O y = 5
Oy = 8
The solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.
Here,
Let's solve the equation step by step to find the value of y:
Combine the y terms on the left side of the equation:
y + 3y + 6 = 26
Combine the y terms on the left side of the equation:
4y + 6 = 26
Move the constant term to the other side of the equation:
4y = 26 - 6
Simplify the right side:
4y = 20
Now, solve for y by dividing both sides of the equation by 4:
y = 20 / 4
y = 5
So, the solution to the equation is y = 5.
Therefore, the correct answer is "O y = 5."
Option C.

Just one simple question
Answer:
i) OC=a+b
ii) BA=a-b
iii)CA=-b
Step-by-step explanation:
i) because it is a parallelogram AC=OB and therefore AC=b
to find OC you do OA+AC which is a+b
OC=a+b
ii) to find BA you do BO+OA
BO=-b as it is the opposite direction
OA=a
so therefore BA=a-b
iii)CA is the opposite of AC which was b so CA=-b

Shen runs each lap in 5 minutes. He will run at most 45 minutes today. What are the possible numbers of laps he will run today? Use n for the number of laps he will run today.
Answer: The possible numbers of laps he will run today = 9
Step-by-step explanation:
Let [tex]n[/tex] = number of laps he will run today.
Given: Time taken for each lap = 5 minutes
Time taken for [tex]n[/tex] laps =[tex]5n[/tex] minutes
If he runs at most 45 minutes, then
[tex]5n\leq45[/tex]
Divide both sides by 5 , we get
[tex]n\leq9[/tex]
Hence, the possible numbers of laps he will run today = 9
