Answer:
$442
Step-by-step explanation:
Multiply the sales price by the discount percentage. This is the total discount that was taken off.
$520 x 15% = $78.
Subtract the discount amount from the sales price. This gives you the amount that the computer costs after the discount.
$520 - $78 = $442
The computer costs $442.
Evan’s family drove to a theme park for vacation.
They drove the same speed throughout the trip.
The first day, they drove 300 miles in 6 hours.
The second day, they drove 250 miles in 5 hours.
The third day, they arrived at the park after driving for 3 hours.
How many miles did they drive on the third day?
- First: Calculate how many miles the family is driving in ONE hour.
There are two equations you can form to solve this.
300 / 6 = mph (miles per hour)
250 / 5 = mph (miles per hour)
300 / 6 = 50
250 / 5 = 50
They are driving 50mph. Now, you need to find out how many miles they drive in three hours.
50 * 3 = 150
Evan's family drove 150 miles on the third day.
Answer:
150 miles
Step-by-step explanation:
The first day, they drove 300 miles in 6 hours so divide 6 by 300. 300 divided by 6 equals fifty. On the third day, they drove half the amount of time, so it would be half the amount of miles because they drove the same speed throughout the trip.
300/2 so the answer to the question is 150 miles.
Express 25 as power with base 5
Answer: express a number in base 5 notation you need to write it in powers of 5. ... 52 = 25 53 = 125 54 = 625. 625 is larger than 613 so I only need a 53 digit, a 52
Step-by-step explanation:
Answer:
POWERS OF 5:
.52 = 25
53 = 125
54 = 625
So 625 is larger than 613
so you will only need 53
but then you also will have 52 so you have 52 as your answer i hope this helps :)

Step-by-step explanation:
find the coordinates of the point which divides the line segment joining the points (4, -3) and (8.5) in the ratio 3:1 internally
Answer:
The coordinates of the division point are (7, 3)
Step-by-step explanation:
The coordinates of the point (x, y) which divides a segment with endpoints (x1, y1) and (x2, y2) at a ratio m1: m2 internally is ([tex]\frac{m1x2+m2x1}{m1+m2}[/tex] , [tex]\frac{m1y2+m2y1}{m1+m2}[/tex] ).
∵ The line segment joining the points (4, -3) and (8, 5)
∴ x1 = 4 and x2 = 8
∴ y1 = -3 and y2 = 5
∵ The point divides the segment at ratio 3: 1
∴ m1 = 3 and m2 = 1
→ By using the rule above
∵ x = [tex]\frac{(3)(8)+(1)(4)}{3+1}[/tex] = [tex]\frac{24+4}{4}[/tex] = [tex]\frac{28}{4}[/tex]
∴ x = 7
∵ y = [tex]\frac{(3)(5)+(1)(-3)}{3+1}[/tex] = [tex]\frac{15-3}{4}[/tex] = [tex]\frac{12}{4}[/tex]
∴ y = 3
∴ The coordinates of the division point are (7, 3)

2(6.75)+1.03+3S=22 therefore 3S = 14.53 divide by 3 so S equals 4.84 per pair of socks
Answer:
each pair of socks cost $2.49
Step-by-step explanation:
Eric spent $22.00, including sales tax on 2 jerseys and 3 pairs of socks. The jerseys cost $6.75 each and the total sales tax was $1.03. How much did each pair of socks cost?
Solution:
The total money spent was $22.00. 2 jerseys costing $6.75 each was bought, the total tax was $1.03. 3 pairs of socks was bought, Let S represent the cost for each pair of socks. The total money spent is the sum of the money spent on jersey, socks and tax. Hence:
2(6.75) + 3S + 1.03 = 22
13.5 + 3S + 1.03 = 22
14.53 + 3S = 22
3S = 22 - 14.53
3S = 7.47
S = 2.49
Hence each pair of socks cost $2.49
simplyfy: 4x + 8 + x -2 -3x
Answer:
2x+6
Step-by-step explanation:
To simplify an expression such as this you must add like terms. Like terms are terms that have the same variable and power. In this expression 4x, x, -3x are like terms and -2 and 8 are also like terms. To add like terms simply add the coefficients and remember adding a negative is the same as subtracting. So, add the previously listed terms 4x + x + (-3x) = 2x, then -2+8= 6. This means the simplified expression is 2x+6.

There are 12 tomato plants in a garden. Each plant has 7 branches ad each branch has 4 tomatoes growing on it. If one-third of the tomatoes are picked, how many tomatoes were picked
Answer:
112
Step-by-step explanation:
4*7=2828*12=336336*(1/3)=112If one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.
Number of picked tomatoes:Number of picked tomatoes=(Growing tomatoes× Tomatoes branch× Tomatoes plant)× One-third
Number of picked tomatoes=(4×7×12)×1/3
Number of picked tomatoes=336×1/3
Number of picked tomatoes=112 tomatoes
Inconclusion if one-third of the tomatoes are picked, the number of tomatoes that were picked is 112 tomatoes.

What is the value of the expression when a = –5 and c = –1? The expression is 8(a + 2c)
Answer:
8(a + 2c) = -56
Step-by-step explanation:
Given that,
An expression : 8(a + 2c)
We need to find the value of the above expression when a = -5 and c = -1.
Put the values of a and c in the given expression.
8(a + 2c) = 8(-5+2(-1))
= 8(-5-2)
= 8(-7)
= -56
Hence, the value of the given expression is -56.

Which line shows the graph of y = 4x - 5 reflected over the y-axis?
y = 4x + 5
y = 4x - 5
Y=2x-5
y = -2x + 5
Answer:
The line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
Step-by-step explanation:
When we reflect a line function over the y-axis, all we need is to negate the x-coordinate or value of 'x', while y-coordinate or y-value remains the same.
Given the function
y = 4x-5
replace x with -x
y = 4(-x) - 5
y = -4x - 5
Thus, the line y = -4x - 5 shows the reflection over the y-axis.
From the attached graph, the blue line i.e. y = -4x-5 represents the reflection over the y-axis.
From the graph, it is clear that that that x-coordinate of y = 4x-5 is negated.
Encuentra la ecuacion de la parabola con vertice en el origen y foco en las cordenadas 0,1en su forma ordinaria y general
Answer:
[tex]x^{2}=4y[/tex]
[tex]y=\frac{1}{4}x^{2}[/tex]
Step-by-step explanation:
Forma ordinaria
La ecuación de la parabola de manera ordinaria está dada por:
[tex](x-h)^{2}=4p(y-k)[/tex] (1)
Donde:
(h,k) es la coordenda del vértice, en nuestro caso (0,0) ya que está en el origen.(h,k+p) es la coordenda del foco, en nuestro caso (0,1).Por lo tanto h = 0, k = 0 y p = 1.
Remplazando estos valores en la ecuación de la parábola, tenemos:
[tex](x-0)^{2}=4*1(y-0)[/tex]
[tex]x^{2}=4y[/tex] (2)
Forma general
La forma general de una parábola esta dada por la siquiente ecuación
[tex]y=ax^{2}+bx+c[/tex]
Reordenando la ecuación (2) tenemos:
[tex]y=\frac{1}{4}x^{2}[/tex]
