Answer:
The coordinates of point X that divides the line in 1:4 are: (3,8/5)
Step-by-step explanation:
When a point divides a line with coordinates (x1,y1) and (x2,y2) in ratio m:n,
the coordinates of point are given by:
[tex](x,y) = (\frac{mx_2+nx_1}{m+n} , \frac{my_2+ny_1}{m+n})[/tex]
Given points are:
(x1,y1) = (5,1)
(x2,y2) = (-5,4)
Putting the values in the formula
[tex]X(x,y) = (\frac{(1)(-5)+(4)(5)}{1+4} , \frac{(1)(4)+(4)(1)}{1+4})\\= (\frac{-5+20}{5}, \frac{4+4}{5})\\=(\frac{15}{5}, \frac{8}{5})\\=(3,\frac{8}{5})[/tex]
Hence,
The coordinates of point X that divides the line in 1:4 are: (3,8/5)

Student can eat 1/8 of a pizza. If there are 24 students in David's class how many pizzas does David need
Answer: 7 boxes of pizza
Step-by-step explanation:
8x3=24
Answer:
David needs 3 pizzas.
Step-by-step explanation:
This is grammatically incorrect, but based on the information provided, I would infer that each student eats *only* 1/8 of a pizza. You would need 3 pizzas, as 3 x 8 =24.
please answer if you can? (This is my math from 8th grade)

What's the recursive rule for the arithmetic sequence described in the following list? Use the rule to find the eighth term of the sequence.
5, 9, 13, 17, 21
Answer:
33
Step-by-step explanation:
T8 = A + (8 - 1) d
T8 = 5 + 7d
T8 = 5 + 7(4)
T8 = 5 + 28
T8 = 33
note : d is the common difference gotten from T2 - T1
Answer:
33
Step by step explanation:
Eight term of the sequence = a + 7d
where:
a= first term
d= common difference
first term = 5
common difference = 4
= 5 + 7(4)
= 5 + 28
= 33

Brita has a monthly budget of x dollars. She spends $1,425 on her mortgage every month. One-third of her remaining budget is spent on recreational activities. Which equation below can be used to determine the amount, in dollars, spent on recreational activities?
Answer:
y = ⅓(x - 1425)
Step-by-step explanation:
Given
Budget = x
Mortgage = 1425
Required
Determine the amount spent on recreational activities.
First, we need to get the balance after she pays her mortgage.
Balance = Budget - Mortgage
Balance = x - 1425
From the question, we understand that she spends ⅓ of the balance on recreational activities.
Represent this with y.
y is calculated as thus:
y = ⅓ of Balance
y = ⅓ * (x - 1425)
y = ⅓(x - 1425)
Hence, the above equation y = ⅓(x - 1425) can be used to calculate the amount spent on recreational activities

Find the area of the shaded region. The graph to the right depicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15.
105 is on the graph
Answer:
Probability =0.8854 (Approx)
Step-by-step explanation:
Given:
Mean μ = 100
Standard deviation σ = 15
Computation:
Z at 70
Z = (70-100)/15
Z at 70 = -2
Z at 120
Z = (120-100)/15
Z at 100 = 1.33
Probability = φ(1.33) - φ(-2.0)
Probability = 0.9082-0.0228
Probability = 0.8854 (Approx)
