Answer:
7 7/4 t - 1
Step-by-step explanation:
The perimeter of the quadrilateral is the sum of all the sides combined together
Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),
Taking the sum;
Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)
Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2
Collect like terms;
Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2
Perimeter = (9t-2t)/4 + 7t -1
Perimeter = 7/4 t + 7t - 1
Perimeter = 7 7/4 t - 1
Which graph shows the solution set of [tex]\frac{x-1}{x-3} \ \textless \ 0[/tex]?
Answer:
Step-by-step explanation:
f(x) = (x - 1)/(x - 3) < 0
The critical points are x = 1 and x = 3
When x < 1, f(x) > 0
When 1 < x < 3, f(x) < 0
When x > 3, f(x) > 0
Note when x = 3 f(x) has no value and when x = 1 f(x) = 0.
I can't see all the graphs very well but there should be a red line between 1 and 3 with a clear circle on x = 1 and x = 3.
Looks like its the last choice.
Challenge A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. of the coins, 16% are pennies and 32% are dimes. There are 6 more nickels than pennies. How much money does the bag contain?
Answer:
Step-by-step explanation:
p+n+d+q=50
p=.16(50)=8
n=p+6=8+6=14
d=.32(50)=16
q=50-p-n-d=50-8-14-16=12
A=8(1)+14(5)+16(10)+12(25)
A.=8+70+160+300
A=538 cents
A=$5.38

Answer:
$1040
Step-by-step explanation:
Firstly, we must lay down all the details given..
●The price increased by 30% that means that the original price which was 100% is now 130%
●The present price which is the original price for now is 100%.
One way we can show these details is by mathematical term, proportional method.
So,
100%= $800
1%=800÷100
130%= 800÷100×130
= $1040

maths easy class 8 whoever gets it I will give u brainlist
Answer:
424 cm²
Step-by-step explanation:
The figure is composed of a square and a trapezium on top
A of square = 18² = 324 cm²
A of trapezium = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 8, b₁ = 18 and b₂ = 7 , then
A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²
Area of hexagonal park = 324 + 100 = 424 cm²

They say.. use Pythagorean theorem formula.... what is it? :) you have to remember it. I'll put it below in case you don't remember
Step-by-step explanation:
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]
and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer
[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]
( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )
361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )
261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y
my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442
they say round to the nearest 10th... soooo..

Diana went fishing for 3 7/12 hours on Friday. She fished for 2 5/6 hours on Saturday. Estimate how long Diana went fishing on Friday and Saturday combined
Answer:
T = 6.41 hours
Step-by-step explanation:
Fishing for Friday = 3 7/12 hours
Fishing for Saturday =2 5/6 hours
We need to find for how long Diana went fishing on Friday and Saturday combined. It means we need to add the time for Friday and Saturday. So,
[tex]T=3\dfrac{7}{12}+2\dfrac{5}{6}\\\\=\dfrac{3(12)+7}{12}+\dfrac{2(6)+5}{6}\\\\=\dfrac{43}{12}+\dfrac{17}{6}\\\\=6.41\ \text{hours}[/tex]
So, the combined timing is 6.41 hours.

Explain how to find the value of y in the equation 6(y+4)=12
Answer:
y=-2 (Please can i have brainliest????)
Step-by-step explanation:
There are different ways to do this but my way, you would distribute 6 to both y and 4, ending up with 6y+24=12. You then subtract 24 from both sides giving you, 6y=-12. Then divide both sides by 6, giving you y=-2
Answer: y=-2
Step-by-step explanation:
First, you would distribute the 6 to both the y and the 4 which would give you 6y+24=12
Then you would subtract 24 from 12 to get -12 ( it would look like 6y= -12 after)
Finally, you would take -12/6 to get -2 so y = -2

a rectangular field is 3x meters long and 2x meters wide its perimeter is 250 meters the value of x is?
Answer:
Given:
Length = 3x m
Breadth = 2x m
Perimeter = 250m
Need to find:
The value of x=?
Solution:
We know,
Perimeter of rectangle = 2×(length + breadth)
Substitute the values!
→ 250m = 2 ×( 3x + 2x) m
→ 250 = 2 × 5x
→ 10x = 250
→ x = 25

Answer:
3.6h - 3.1d + 13
Step-by-step explanation:
Combine like terms. Like terms have same variables.
Like terms : (i) 6h and (-2.4h) (ii) -8.1d and 5d
6h + (-8.1d) - 13 + 5d - 2.4h = 6h - 2.4h + (-8.1d) + 5d - 13
= (6 - 2.4)h + (-8.1 + 5)d - 13
= 3.6h - 3.1d + 13
