Answer:
no
Step-by-step explanation:
: Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
How do you solve this? Please helppp what’s the answer???
Answer:
I won't be able to give you a numerical answer but that's not what your question's asking anyway. Just put a dot at the coordinates (0,-3) and one at (-2,3) and connect them. That's your first line. For the second question put a dot at the intersections (0,1) and one at (-4,-3) and connect them. You should be able to find a point where the two lines intersect. That's the point you need. If you still can't find it, then continue the lines or message me at riztofu on insta. I'll solve your question then.

Directions: Identify the rise, run, and slope of the line below.
Answer:
rise= -2 run= -4 slope= -1/2
Step-by-step explanation:
slope= rise/run
since rise=-2 and run=-4, slope=-2/4, but we have to simplify, so slope=-1/2

What is the total surface area of the rectangular prism?
Answer:
Total surface = 102.4 cm^2 (second answer in the list of options)
Step-by-step explanation:
Notice that we need to add the surface of 4 rectangles, two have smaller sizes than the other two. A pair of rectangles are 7.2 cm x 4 cm = 28.8 cm^2, while the other pair has 7.2 cm x 2 cm = 14.4 cm^2
There are also two equal bases each one of size 4 cm x 2 cm = 8 cm^2
Now we add two of each of the individual surfaces discussed above to complete the total surface area:
2 * 28.8 + 2 * 14.4 + 2 * 8 = 102.4 cm^2
which agrees with the second answer option provided.

Find the measure of the angle indicated in bold
Answer:
x=5
Step-by-step explanation:
hey there
the angles given are corresponding angles meaning that they are congruent
so we set up an equation
23x-5=21x+5
step 1 subtract each side by 5
5-5 cancels out
-5-5=-10
now we have
23x-10=21x
step 2 subtract each side by 23x
21x-23x=-2x
now we have
-2x=-10
step 3 divide each side by 2
-10/-2=5
so we can conclude that
x=5

Paula's time swimming in the Ironman Triathlon was 1 hour 25 minutes. Her time biking was 5 hours longer than her swimming time. She ran for 4 hours 50 minutes. How long did it take her to complete all three parts of the race? Use the model to help you organize your thinking.
Answer: 12 hrs 40 mins
Step-by-step explanation:
The swimming time was 1 hour 25 minutes.
Her biking time was 5 hours longer than the swimming time so it was:
= 1 hr 25 mins + 5 hours
= 6 hours 25 mins
Her running time was 4 hrs 50 mins.
Add them all up to find the amount of time ran. First add up the minutes:
= 25 + 25 +50
= 1 hr 40 minutes
Hours = 1 + 6 + 4
= 11 hours
Total:
= 11 + 1 hr 40
= 12 hrs 40 mins

A culture of bacteria has an initial population of 980 bacteria and doubles every 9 hours. Using the formula P_t = P_0\cdot 2^{\frac{t}{d}}P t =P 0 ⋅2 d t , where P_tP t is the population after t hours, P_0P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 13 hours, to the nearest whole number?

The dimensions of a trapezoid are shown below. Which equation could you use to find the Area of the Trapezoid?
Answer:
See Explanation
Step-by-step explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
[tex]Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height[/tex]
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
[tex]Area = \frac{1}{2} * (6cm + 12cm) * 4cm[/tex]
[tex]Area = 18cm * 2cm[/tex]
[tex]Area = 36cm^2[/tex]

Find the sum. Write your answer in scientific notation.
(1.7 x 103) + (3.5 x 103) = 0
Answer:
5200
Step-by-step explanation:
First solve 10^3 which will give you 1000 then multiply it by 1.7 to get 1700. Then multiple the answer for 10^3, which is 1000, by 3.5 to get 3500. The add the two answers together to get the answer. Which is 1700+3500=5200.

Answer:
15.4
Step-by-step explanation
From the diagram, we are given;
Adjacent = 12
Hypotenuse=x
Angle of elevation =39°
Using the SOH CAH TOA identity
Cos 39 = 12/x
x = 12/cos39
x = 13/0.7771
x = 15.44
Hence the value of x to nearest tenth is 15.4

Answer:
C
Step-by-step explanation:
∠ 5 and ∠ 8 are adjacent angles and are supplementary, sum to 180° , then
∠ 8 + ∠ 5 = 180°
∠ 8 + 45° = 180° ( subtract 45° from both sides )
∠ 8 = 135° → C
