Answer:
For the chart, the missing number on top is 10. the bottom numbers are 1.5 then 9.
For the question, all of the numbers equal the ration 5:3.
Question 2: Yes. 30/x=2/4 which equals 60 (minutes) which is an hour.
Step-by-step explanation:
1A:
2.5 amount of water - 1.5 amount of pasta
10 amount water - 6 amount pasta
15 amount water - 9 amount pasta
2.5 : 1.5
5 : 3
10 : 6
15 : 9
1B. these quantities are proportional because they can all be simplified to the same unit rate of 5 : 3.
2. Johnny is correct. The rate is 4 : 2, with a unit rate of 2 : 1. If you multiply both sides by 30 (how many inches deep the hot tub is) you get a ratio of 60 : 30, meaning it would take an hour to fill up the tub.

Answer:
30 DegreesStep-by-step explanation:
As per table we see the difference and pattern of decrease 1/2 times every 15 minutes:
1:00 PM 92 Degrees 1:15 PM 60 Degrees = -32 Degrees 1:30 PM 44 Degrees = -16 Degrees 1:45 PM 36 Degrees = -8 DegreesExpected

Answers
Answer:
A. [tex] PR = 80.6 yd [/tex]
B. Perimeter = 190.6 yd
Step-by-step explanation:
A. Distance between P(10, 50) and R(80, 10):
[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] PR = \sqrt{(80 - 10)^2 + (10 - 50)^2} [/tex]
[tex] PR = \sqrt{(70)^2 + (-40)^2} [/tex]
[tex] PR = \sqrt{4,900 + 1,600} [/tex]
[tex] PR = \sqrt{6,500} [/tex]
[tex] PR = 80.6 yd [/tex] (nearest tenth)
B. Distance around the park = Perimeter = PR + PQ + QR
PR = 80.6 yd
PQ = |50 - 10| = 40 yd
QR = |80 - 10| = 70 yd
Perimeter = 80.6 + 40 + 70
Perimeter = 190.6 yd

Written as a simplified polynomial in standard form, what is
the result when (2x – 5)2 is subtracted from x-10?
Answers
Answer:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]
Step-by-step explanation:
As we have to subtract [tex]\left(2x\:-\:5\right)^2[/tex] from [tex]\left(x-10\right)[/tex]
so
[tex]\left(x-10\right)-\left(2x\:-\:5\right)^2[/tex]
solving and simplifying the polynomial in standard form
[tex]\left(x-10\right)-\left(2x-5\right)^2[/tex]
[tex]\mathrm{Remove\:parentheses}:\quad \left(a\right)=a[/tex]
[tex]=x-10-\left(2x-5\right)^2[/tex]
[tex]=x-10-\left(4x^2-20x+25\right)[/tex] ∵ [tex]\left(2x\:-\:5\right)^2=\:4x^2-20x+25[/tex]
[tex]=x-10-4x^2+20x-25[/tex]
[tex]=-4x^2+21x-35[/tex]
We know that standard form means that the terms of the expression are ordered from biggest exponent to lowest exponent.
Thus, a simplified polynomial in standard form is:
[tex]\left(x-10\right)-\left(2x-5\right)^2=-4x^2+21x-35[/tex]

-2.2 * 3.7= 8.14
PLS ANSWER THIS I NEED YOUR HELP
AND IF YOU DO HELP I PROMISE I WILL MAKE THE YOU BRAINLIEST
Answers
Step-by-step explanation:
It is given that,
-2.2 × 3.7 = 8.14
The first number is -2.2
The second number is 3.7
We know that, (-) × (+) = - (the answer is a negative)
If we multiply -2.2 and 3.7, we will get -8.14.
But in the given case, the answer is 8.18 instead of -8.14. Hence, this is the only error.

Answers
Answer:
B. $39550
Step-by-step explanation:
The expression for the function is not well-formatted, find the correct format in the solution bellow
Step one:
given data
We are told that the function of the cost is
[tex]C(t) = 0.04t^3- 0.1t^2 + 5.5t[/tex]
instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above
substituting we have
[tex]C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550[/tex]

He probably won't get too suspicious if you get 100% on three quizzes when you regularly get A's in that class. A ninety-something percent jump to a 100 is less than a 10-point increase.
That being said, it's still best to learn the math so that you don't become dependent on using Brainly for every question. Maybe only use it when you're having a lot of trouble with a particular problem or concept; but some of the explanations on here are actually really helpful in teaching things.

options: given, vertical angles, corresponding angles, and transitive
Answers
Answer:
1. Given
2. Vertical angles
3. Transitive
4. Corresponding Angles
Step-by-step explanation:
1. Number one is given because it is the statement that is given
2. Number two is vertical angles because they are two opposite angles that are formed by the same lines. The statement also says they are congruent, which is true of vertical angles.
3. From the given answers 3 must be transitive because <2=<4 and <2=<6. Although alternate interior angles is also an appropriate answer.
4. Number four must be corresponding because they are on the same side of the intersection of the lines, so they are both in the top right. Also, the statement says they are congruent which is true of corresponding angles.
