Answer:
M=K*L
(K is the constant we use)
when L=35cm, M=80,
meaning K=80/0.35=228.571428571
so when L=0.3
we do 0.3*228.571428571=68.5714285713
rounded to 2dp= 68.57kg
9514 1404 393
Answer:
50.38 kg
Step-by-step explanation:
The mass is proportional to the cube of edge length, So, if the edge length is decreased by a factor of 30/35 = 6/7, the mass is decreased by a factor of (6/7)³. That is, the smaller cube will have a mass of ...
(80 kg)(6/7)³ ≈ 50.38 kg
__
If you want to write an equation, you can write the equation for the proportionality:
M = kL³
80 kg = k(0.35 m)³
k = 80/0.35³ kg/m³
Then for the shorter length, we have ...
M = k(0.3 m)³ = 80(0.3/0.35)³ kg = 80(6/7)³ kg ≈ 50.38 kg . . . . as above

Use a calculator, spreadsheet, or another tool to solve for the unknown sides of the given right triangle. The length of the hypotenuse is 12. a is the length of the side opposite the 10 degree angle and b is the length of the opposite angle B. Round your answers to four decimal places.
Answer:
27
Step-by-step explanation:
2 TIMES 3
The length of the side a and b is 2.0837 and 11.8176 respectively.
Length of side a and b to be determine, hypotenuse is 12 and a is the length of the side opposite the 10 degree angle and b is the length of the opposite angle B.
Trigonometry is branch of mathematics that helps in elevation and angle problems.
Let assume that one angle of triangle is right angle.
So in right angles triangle,
hypotenuse = 12
cos10 = length of b /12
length of b = 12 cos10
length of b = 11.8176
Now,
sin 10 =length of a/ 12
length of a = 12 sin10
length of a = 2.0837
Thus, the length of the side a and b is 2.0837 and 11.8176 respectively.

What is the distance of line segment AD given the following points, A = -7, B = 5, C = 8, and D = 14?
Answer:
21
Step-by-step explanation:
Since exact coordinates aren't given, you would have to think of the two points on a number line. The distance from the two points on a number line would be 21. You could also add the absolute values of the two points together. This would basically turn -7 into a positive, and then when the absolute values are added(7 + 14), you would get 21.
Dallas was told to run around the perimeter of the high
school as a warm-up for football practice. What is the
total distance that Dallas will run?
148 yards
166 yards
196 yards
256 yards
Answer:
Option (4)
Step-by-step explanation:
Perimeter of a polygon is the sum of measures of all sides of the polygon.
From the picture attached,
Distance run by Dallas = Perimeter of the ground
= 48 + 50 + 9 + 30 + 30 + 30 + 9 + 50
= 256 yards
Total warm up run by Dallas = 256 yards
Therefore, Option (4) will be the correct option.

Answer:
Step-by-step explanation:
The standard form equation is y = mx + k where m is the slope and k is the y-intercept.
In this problem, it is first asking you for the slope of y = 2x + k. Therefore, the slope would be 2. In the next blank, it is asking for the slope of y = -1/2x + k. In that case, it would have a slope of -1/2.
When you multiply these slopes together, you'll notice that the you'll get -1. Whenever the slopes of 2 equations multiplied together is equal to -1, then those 2 equations are perpendicular to each other.
Finally, it is asking if the statement that says the lines are perpendicular is true. Like mentioned above, because the slopes multiply to -1, they are perpendicular equations making the statement always true.
Answers: 2, -1/2, -1, always.

A number less than 85 has 26 and 6 as a factor what is my number
First, write out the multiples of 6 and 26. Then find the common multiple they share that is immediately less than 85. (I do 26 first since it will have less multiple and it will give me an idea of what to look for within the multiples for 6)
26: 26, 52, 78 (anything more will be over 85 and we need a number less than 85)
6: 6, 12, 18, 24, 30, 36, 42, 48, 56, 72, 78 (I stopped at 78 since any number after this will be larger than 85)
I now look to find the multiple that both 26 & 6 shares that is also less than 85 and it landed me on the number 78!
The Answer: 78

$24,000 for new Honda, 2.75% interest rate for 4 years. What is the monthly payment? ( Explanation needed)
Answer:
(Use the attached formula)
24,000 for 4 years (48 months) at 2.75% interest
We divide rate by 1,200 which equals 0.0022916667
Monthly Payment = 0.0022916667 + {(0.0022916667 / [(1.0022916667)^48 -1]} * 24,000
Monthly Payment = 0.0022916667 + (0.0022916667 / (1.1161375981 -1) * 24,000
Monthly Payment = [0.0022916667 + (0.0022916667 / 0.1161375981 ] * 24,000
Monthly Payment = [0.0022916667 + 0.0197323411 ] *24,000
Monthly Payment = 0.0220240078 * 24,000

Mrs.Rodriquez is purchasing trophies for each child that plays little league she wants to spend no more than $7.00 per thropy
Answer:
7 trophies for $49.00
5 trophies for $30.00
-----------------------------------
Explination:
It says that she wants to pay no more than 7 dollars for each trophy she buys, which means 7 and less. So we have to multiply 7 x the number of trophies, And if it gives you the excact number or less its correct.
So we multiply
7 x 7 = 49 (The excact number, correct)
9 x 7 = 63 (The price they are selling it at is higher, incorrect)
12 x 7 = 84 (The price they are selling it at is higher, incorrect)
5 x 7 = 35 (Paying less, Correct)
3 x 7 (The price they are selling it at is higher, incorrect)
