Which is the area between the x-axis and y=x from x=1 to x=6
Answer:
I am going to answer using calculus. Let me know if you instead were looking for an algebraic method. Take the definite integral from 3 to 6 of xdx. [x^2/2]3 to 6= 18-(9/2)= (36-9)/2= 27/2. The area is 27/2
How do you solve these two problems please explain step by step
Answer:
1) [tex]x=15, y=41[/tex]
2) [tex]x=6, y=24[/tex]
Step-by-step explanation:
1)
The two triangles are similar by AA similarity.
That means [tex]5x-5=4x+10[/tex].
We can add [tex]5[/tex] to both sides to get [tex]5x=4x+15[/tex].
We can then subtract [tex]4x[/tex] from both sides to get [tex]x=15[/tex].
We know that the [tex](5x-5)+(6y-4)=180[/tex] because they both lie on a straight line.
We can plug in for [tex]x[/tex] to get [tex](5(15)-5)+(6y-4)=75-5+6y-4=6y-66=180[/tex].
We can divide both sides of the equation by [tex]6[/tex] to get [tex]y-11=30[/tex].
We then add [tex]11[/tex] to both sides to get [tex]y=41[/tex].
So, [tex]\boxed{x=15, y=41}[/tex] and we're done!
2)
Because the two bases of a trapezoid are parallel, meaning adjacent top and bottom angles sum to [tex]180^{\circ}[/tex], we have that [tex]90+3y+18=180[/tex].
We can subtract a [tex]90[/tex] and an [tex]18[/tex] from both sides to get [tex]3y=72[/tex].
We then divide both sides of the equation by [tex]3[/tex] to get [tex]y=24[/tex].
We do the same thing for [tex]x[/tex]. On the other side of the trapezoid, we have that [tex]15x+30+10x=180[/tex].
We combine like terms on the left side to get [tex]25x+30=180[/tex].
We subtract a [tex]30[/tex] from both sides to get [tex]25x=150[/tex].
We divide both sides of the equation to get [tex]x=6[/tex].
So, [tex]\boxed{x=6, y=24}[/tex] and we're done!

A card is drawn from a 52-card deck, the result is written down, and then the deck is shuffled. A card is drawn. What is the probability that at least one of the two cards was red? Write your answer as a percent
Answer:
1/2 or 50%
Step-by-step explanation
Answer:
75%
Step-by-step explanation:
To find probability of one being red, do 1 minus probability of being black.
1/2*1/2=1/4
1-1/4=3/4
=75%

Jose needs 6.2 lb of organic blueberries to make smoothies. Organic blueberries are on sale for $2.85 per pound. Jose estimates that he will need $12 to buy the 6.2 lb of blueberries. What is Jose’s error?
1. Jose did not make an error. His estimate of $12 is correct.
2. Jose incorrectly rounded $2.85 down to $2. The estimate should be $18.
3. Jose incorrectly rounded 6.2 up to 7.
4. Jose incorrectly multiplied 2 and 7. The estimate should be $14.
Answer: Jose incorrectly rounded $2.85 down to $2. The estimate should $18.

Show that the two triangles ABC and DEF are congruent by the
HL theorem.
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.
The Hypotenuse-Leg theorem states that two right triangles are congruent if and only if their hypotenuses and any of their corresponding legs are congruent. That is to say:
[tex]\overline {AC} \cong \overline {DF}[/tex], [tex]\overline{BC} \cong \overline {EF}[/tex]
[tex]AC = DF, BC = EF[/tex]
[tex]\sqrt{AB^{2}+BC^{2}} = \sqrt{DE^{2}+EF^{2}}[/tex], [tex]BC = EF[/tex]
If we know that [tex]AB = 10[/tex], [tex]BC = 4[/tex], [tex]DE = 10[/tex] and [tex]EF = 4[/tex], then we have the following outcomes:
[tex]\sqrt{10^{2}+4^{2}} = \sqrt{10^{2}+4^{2}}[/tex]
[tex]4 = 4[/tex]
Since hypotenuses and legs have the same length, then both are congruent and thus, triangles ABC and DEF are congruent.

HELP ASAP PLS
Answer:
inconsistent, none
Step-by-step explanation:
Write both equations in slope-intercept form to see if the lines are parallel.
These two lines have slope m = −2 and different y-intercepts, therefore they are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
The system of equations 4x + 2y = −8 6x + 3y = 9 is inconsistent and has no solutions.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
We need to write both equations in slope-intercept form to see if the lines are parallel.
4x+2y=-8
2y=-8-4x
y=-4-2x,
y=-2x-4, m₁=-2
and 6x+3y=9
3y=9-6x
y=-2x+3, m₂=-2.
So two lines have slope m = −2 and different y-intercepts,
It means two line are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
Hence 4x + 2y = −8 , 6x + 3y = 9 is inconsistent and has no solution.

The Hulk just flew into the Boston airport to visit some family, but due to car problems, they are
unable to pick him up. He only has $20 on him. He needs to call a cab that costs $1.75 initially and
$.65 per mile. How far will he be able to go? If his family lives 25 miles away, will the cab be able to
get him to his family?
Answer:
Yes, he will be able to afford 25 miles
Step-by-step explanation:
20.00 - 1.75 = 18.25
He will have $18.25 after the initial payment.
18.25 / 0.65 = 28~
He will be able to go 28 miles with the 18 dollars he has left.

The perimeter of a triangle is 17x−5 units. One side is 3x+5 units and another is 8x−3 units. How many units long is the third side?
9514 1404 393
Answer:
6x -7 units
Step-by-step explanation:
Let c represent the length of the third side. The perimeter is the sum of the three side lengths.
P = a + b + c
(17x -5) = (3x +5) +(8x -3) +c
17x -5 = 11x +2 + c . . . . . . . . . . . . collect terms
6x -7 = c . . . . . . . . . . . . . . subtract 11x+2
The third side is 6x -7 units.
