Rosa and Albert receive the same amount of allowance
each week. The table shows what part of their allowance
they each spent on video games and pizza
A: Who spent more or their allowance no video games? Write an inequality to compare the portion spent on video games.
Answers
Answer:
0.4x < 0.5x
Step-by-step explanation:
Let x = Amount of money Rosa and Albert earn each week
Rosa:
Rosa spends 0.4(x) and 2/5(x) each week on video games and pizza
That equals to :
0.4x + 0.4x0.8xRosa spends 0.8x, or 80% of her allowance on video games and pizza
Albert
Albert spends 1/2(x) and 0.25(x) each week on video games and pizza
0.5x + 0.25x0.75xAlbert spends 0.75x, or 75% of her allowance on video games
Rosa spends 0.4x on video games, and Albert spends 0.5x.
0.4x ≤ 0.5x

Find the value of the variables
Answers
Answer:
x = 15
y = 12
z = 20
Step-by-step explanation:
For right angle x^2 + z^2 = (9 + 16)^2 => x^2 + z^2 = 625
then z^2 = y^2 + 16^2 => y^2 = z^2 - 256
and x^2 = y^2 + 9^2 => y^2 = x^2 - 81
so z^2 - 256 = x^2 - 81
z^2 = x^2 + 175
replace z^2 = x^2 + 175 into the first equation
x^2 + (x^2 + 175) = 625
2x^2 = 450
x^2 = 225
x = 15
If x = 15 => 15^2 + z^2 = 625 => z^2 = 400 => z = 20
y^2 = z^2 - 256 => y^2 = 400 - 256 = 144
then y = 12

Sample Response: First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.
What did you include in your response? Check all that apply.
If a2 + b2 = c2, the triangle is right.
If c2 < a2 + b2, the triangle is acute.
If c2 > a2 + b2, the triangle is obtuse.

factorise x² + 5x - 36
Answers
Answer:
[tex](x-4)(x+9)[/tex]
Step-by-step explanation:
To factorize a quadratic equation, take into consideration that:
If [tex]ax^2+bx+c[/tex],
then [tex](x+w)(x+v)[/tex]
ONLY IF [tex]w+v=b[/tex] and [tex]wv=c[/tex].
To start, find factors of c, which in this case, -36:
1 and -36
2 and -18
3 and -12
4 and -9
6 and -6
-6 and 6
-4 and 9
-3 and 12
-2 and 18
-1 and 36
Try out which pair of numbers add up to b, which in this case, 5:
[tex]1+(-36)\neq 5\\2+(-18)\neq 5\\3+(-12)\neq 5\\4+(-9)\neq 5\\6+(-6)\neq 5\\-6+6\neq 5\\-4+9=5\\-3+12\neq 5\\-2+18\neq 5\\-1+36\neq 5[/tex]
The only pair of numbers that add up to 5 is -4 and 9, so:

Answers
Answer:

Because triangle QSR is isosceles ∠SQR=∠SRQ=35°. The sum of the angles in a triangle is 180°, so ∠QSR=180°-35°-35°=110°. The measure of a straight line is 180°, so ∠PSQ=180°-110°=70°. Because triangle PSQ is also isosceles ∠PSQ=∠PQS=70°. Then, ∠QPS=180°-70°-70°=40°.
