The perimeter of a rectangular tabletop is 384 cm. It's width is 3/5 of its length. Find the dimensions of the tabletop
Answer:
Length: 120cm, Width: 72cm
Step-by-step explanation:
Let x = length
Let 3x/5 = width
2x+2(3x/5)=384
2x+(6x/5)=384
16x/5=384
16x=1920
x=120cm
Substitute 120 for x in width
360/5 = width
width = 72cm
Need help with these 2 equations, thanks if you do :)
Answer:
X=6+2=8 * 6= 48
Step-by-step explanation:
If you divide 48 by 6 you get 8 then you - 2 and you get six. so x =6
how do i solve 9 - 2x = 15 *EXTRA POINTS
Answer:
[tex]x=-3[/tex]
Step-by-step explanation:
[tex]9-2x=15[/tex]
Subtract 9 from both sides:
[tex]9-2x-9=15-9[/tex]
[tex]-2x=6[/tex]
Divide both sides by -2:
[tex]\frac{-2x}{-2}=\frac{6}{-2}[/tex]
[tex]x=-3[/tex]
find the perimeter and area of this figure.
Hey there! I'm happy to help!
AREA
To find the area of a parallelogram, you multiply the base by the height.
12(6)=72
The area is 72 square centimeters.
PERIMETER
The two diagonal sides are 8 cm and the two bases are 12 cm.
8+8+12+12=40
The perimeter is 40 cm.
Have a wonderful day! :D
A student is given a quadratic equation in vertex form. He determines the vertex and axis of symmetry, and then sketches the parabola so that it is symmetrical about the axis of symmetry. Is this sufficient? Explain.
Answer:
The information with which the parabola is constructed is insufficient
Step-by-step explanation:
The vertex form of a quadratic equation is given as follows;
f(x) = a(x - h)² + k
The steps to draw the graph of a quadratic function given in vertex form, we are required to do the following;
1) Definition of the variables, (a, h and k) of the quadratic equation (given in vertex form)
The vertex of the quadratic equation in vertex form is (h, k)
2) Given that the vertex point is given, the vertex point is then plotted on the graph
3) Draw the parabola axis of symmetry that passes through the vertex point
4) Determine the direction to which the parabola opens from the sign of the variable a as follows;
i) When a is positive, the parabola opens upwards
ii) When a is negative, the parabola opens downwards
5) Determine if the parabola has x-intercepts and plot them
A parabola has x intercepts when;
i) The parabola opens downwards, that is, the variable, a, is negative and also the vertex (h, k) is above the x-axis or k is positive
ii) The parabola opens upwards, that is, the variable, a, is positive and also the vertex (h, k) is below the x-axis or k is negative
6) Determine y-intercepts and plot them as follows;
At the y-intercept, x = 0, therefore;
f(x) = a(x - h)² + k
f(0) = a(0 - h)² + k = a·h² + k
6) If any additional points are required, they should plotted and then the graph of the function is then drawn making sure to be symmetrical about the vertex and to pass through all the plotted points.
a thirty-year-old woman decides to pay $390 for one year life insurance policy with coverage of 150000. the probability of her living through the year is 0.9976. what is her expected value for the insurance policy
Answer:
5
Step-by-step explanation:
The expected value is −390(0.9976) + (150,000 − 390)( 1 − 0.9976) = −$30

What is the slope of the line below? Be sure to scroll down first to see all
answer options
Answer:
A ) -4/3
how to calculate slope-
(Y2 - Y1) / (X2 - X1)
Answer:
A
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 3) and (x₂, y₂ ) = (3, - 9) ← 2 points on the line
m = [tex]\frac{-9-3}{3+6}[/tex] = [tex]\frac{-12}{9}[/tex] = - [tex]\frac{4}{3}[/tex] → A

3| -8x | +8 = 80
helpp
Answer:
x=8.625
Step-by-step explanation:
ok so the lines mean absolute value so its actuall positive soyou get 3+8x+8=80
so add 3 and 8 to get 11+8x=80
subtract 11 to get 8x=69
then divide it by 8 so x is by itself
x=8.625 hope this helped :)
Answer:
x = 3 , x = -3
Step-by-step explanation:
3 | -8x | + 8 = 80
3 | -8x | = 72
Solve the negative and positive case:
Negative-
-3 ( -8x ) = 72
24x = 72
x = 3
Positive-
3 (-8x ) = 72
-24 = 72
-x = 3
x = -3

In a badminton tournament each player played one game with all other players. Number of players participated in the tournament if they played 105 games
Answer: 15 players.
Step-by-step explanation:
number of games played in the tournament = 105 games
nunber of games played by each player against another = 1 game each.
Solution:
Number if player who participated in the tournament.
if each player played a game against every other player, and they were 105 games played at the tournament.
n ( n – 1 ) /n = m
= n ( n – 1 ) 2 = 105
open the bracket
n^2 – n = 210
n^2 – n – 210 = 0
( n – 15 ) ( n + 14 ) = 0
n = 15
15 players Participated In the tournament.

What was the average number of calls Corina received over the course of the week?
A. 42 calls B.7 calls
C. 8 calls D.6 calls
Answer:
D.6 calls
Step-by-step explanation:
To find the average first we need to add up all the numbers

42÷7 and 6
6 Brett is going to buy some bird food. Bird food is sold in 200 g boxes costing
£2.50 and in 1000 g boxes costing £10.50. Which box of bird food gives the
better value for money? You must show your working.
1000 g boxes costs £10.50
Cost of 200g in 1000g box = 10.50/5 = 2.10
200 g box costs £2.50
So, buying 1000g box gives better value for moneyHope this will help....
Answer: 1000g Bird Food gives the better value for money because when you muliply 2.5- pounds times 5 you get 12.50 pounds for 1000g but not in the case for 1000g for 10.50 pounds
Step-by-step explanation:
200g Bird Food - 2.50 pounds
1000g Bird Food - 10.50 pounds

Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation [tex]2x+6+2x+6=4x+12[/tex]
When DF and FE is added your answer should equal DE
So you write the equation [tex]4x+12=2x+36[/tex] to find x and once x is found substitute your answer for x
[tex]4x+12(-12)=2x+36(-12)[/tex] subtract 12 on both sides 36-12= 24
[tex]4x=2x+24[/tex] subtract 2x on both sides 4x-2x=2x
[tex]2x=24[/tex] divide 2 into both sides 24/2=12 x=12
[tex]4(12)+12=2(12)+36[/tex]
4x12=48+12=60 2x12=24+36=60
