Step-by-step explanation:
Eight oranges and four apples costs $176. Three oranges and fifteen apples cost $335. How much would two oranges and five apples cost?
$204
$124
$116
$76
$136
Answer: $124
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations:
8 x + 4 y = 176
3x + 15 y = 335
Cost = sum of products (number of fruits x price per unit)
Where x is the price per orange and y is the price per apple.
We have to multiply the first equation by 3 ; the second equation by 8; and subtract the first equation to the second:
24x +120y =2680
24 x +12y = 528
_______________
108y =2152
Solving for y
y = 2152/108
y= 20
Replacing y =20 in any equation:
8x + 4 (20)=176
8x+80=176
8x =176-80
8x =96
x =96/8
x=12
Finally we have to calculate how much would two oranges and five apples cost.
2x+5y = 2(12)+5(20)= 24+100= $124

Answer:
Project 4 Score ; 41
Step-by-step explanation:
Assuming that Project 4's score is x;
( Project 1 + Project 2 + Project 3 + Project 4 ) / 4 ⇒ take to substituting the value of each Project, provided Project 4's score being x;
45 = 42 + 49 + 48 + x / 4 ⇒ combine like terms,
45 = ( 139 + x ) / 4 ⇒ let 4 be a common denominator among numerator terms,
45 = 139 / 4 + x / 4 ⇒ divide 139 over 4,
45 = 34.75 + x / 4 ⇒ subtract 34.75 from either side,
10.25 = x / 4 ⇒ Multiply either side by 4,
x = 41 = Score of Project 4,
Solution; Project 4 ⇒ 41

What is linear regression?Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables.
We know that the y-coordinates of the regression line y=mx+c are (0,c) depicting that c is the y-intercept, corresponding x-coordinate is 0.
So, the model predicts that a student who didn't study at all will have an average score of 373737 hours. So, the correct option is option D.
Thus, The model predicts that a student who didn't study at all will have an average score of 373737 hours. So, the correct option is option D.

A fabric merchant sells fabric at $66 (including the
10% GST) to a dressmaker. The merchant makes $60
on the sale and passes the $6 GST onto the Australian
Tax Office (ATO)
A dressmaker uses the fabric and sells the product
onto a retail store for $143 (this includes the $13
GST). As the dressmaker has already paid $6 in GST
when they bought the fabric they have a GST tax credit
of $6 and they pass on the $7 to the ATO.
The retailer sells the dress for $220, including $20
GST. As the retailer has already paid $13 in GST to the
dressmaker, they are required to forward the extra $7 to the ATO.
The consumer who buys the dress bears the $20 GST included in the price.

What is the median of the number in the dataset [29,3,50,9]?
Answer:
19
Step-by-step explanation:
If you order the Numbers from Least to Greatest
3,9,29,50
9 and 29 are in the middle
(29 +9) Divided by 2 is 19 so your median is 19
Answer: 19
Step-by-step explanation:
The first thing you have to do is order the numbers from least to greatest: 3, 9, 29, 50.
Next you have to find out which number is in the middle, but since there are an even set of numbers there will be 2 numbers in the middle. The 2 numbers in the middle would be 9 and 29.
The next step is to find the mean, or average of 9 and 29. To find the mean of something you have add all the numbers together and divide the sum by the amount of number there are. So we would have to add 9+29 which is 38, then we have to divide 38 by 2 since there are 2 numbers. 38 divided by 2 is 19.
So that means the median is 19.

If f(1)=6 and f(n)=-5f(n-1)-4 then find the value of f(5)
Answer:
3126
Step-by-step explanation: f(1)=6 and f(n)=5f(n-1)-4. This means that next number is 5 times previous number minus 4.
f(2)=5f(1)-4 =5x6-4 = 30-4 = 26
f(3)=5f(2)-4 =5x26-4 = 130-4 = 126
f(4)=5f(3)-4 =5x126-4 = 630-4 = 626
f(5)=5f(4)-4 =5x626-4 = 3130-4 = 3126
The fifth term of the sequence is 4166
Given the recursive function expressed as;
f(n)=-5f(n-1)-4
If f(1 ) = 6
f(2) = -5f(1) - 4
f(2) = -5(6) - 4
f(2) = -30 - 4
f(2) = -34
If n = 3
f(3) = -5f(2) - 4
f(3) = -5(-34) - 4
f(3) = 170 - 4
f(3) = 166
If n = 4
f(4) = -5f(3) - 4
f(4) = -5(166) - 4
f(4) = -830 - 4
f(4) = -834
If n = 5
f(5) = -5f(4) - 4
f(5) = -5(-834) - 4
f(5) = 4170 - 4
f(5) = 4166
Hence the fifth term of the sequence is 4166

C. 627
D. 1,253
Answer: B
Step-by-step explanation: I worked it out but have doubts
The length of each side of the square base is 35 meters, option B is correct.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The volume of the pyramid is 9,039
The height is of 21.6 meters.
We need to find the length of each side of the square base.
V=1/3b²h
9039=1/3×b²×21.6
9039=7.2b²
Divide both sides by 7.2
b²=1255.4
Take square root on both sides
b=35.4
b=35
Hence, the length of each side of the square base is 35 meters, option B is correct.
