Answer:
31 : 41
Step-by-step explanation:
Given that Ravi's mass is 31kg . And his brother is 10 kg heavier than him . So his weight will be 31kg + 10kg = 41kg. So we have ,
[tex]\begin{cases}Mass \ of \ Ravi = 31kg \\ Mass of Brother \ = \ 41kg \end{cases}[/tex]
Therefore their total mass = 31 + 41 = 72 kg .
Therefore the ratio will be 41:72 .
The ratio of Rajar's mass to their total mass is 41:72.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, Ravi's mass is 31 kg.
His brother, Rajar, is 10 kg heavier than Ravi.
Weight of Rajar is 31+10=41 kg
Total weight =31+41
= 72 kg
The ratio of weights = 41:72
Therefore, the ratio of Rajar's mass to their total mass is 41:72.

Taylor bought some jeans on sale. The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans. Find the amount of money Taylor spent,
Answer:
30
Step-by-step explanation:
Let the amount of money Taylor spent = x
The number of jeans she bought is 1-fith the amount of money she spent. She bought 6 jeans.
Hence
1/5 × x = 6 jeans
x/5 = 6 jeans
Cross Multiply
x = 5 × 6 jeans
x = 30
The amount of money Taylor spent = 30
Use the Pythagorean Theorem to find the distance between points A and D.

Step-by-step explanation:
Mrs.Zomoro is 36 years old and her son is 4.When will the mother be thrice as o old as her son?
Answer:
12 years
Step-by-step explanation:
Represent the mother's age by m and the son's by 4. Currently m = 36 years old.
In x years the mother will be three times as old as her son:
mother: 36 + x years old
son: 4 + x years old
The pertinent equation to solve is:
36 + x = 3(4 + x)
Performing the multiplication, we get:
36 + x = 12 + 3x, or
24 = 2x. Then x = 12.
Check: In 12 years, will the mother's age be 3 times the son's age?
Does 36 + 12 = 3(4 + 12)?
Does 48 = 48? YES
The mother will be 3 times as old as her son in 12 years from now.
Liam had 75% more magnets than John at first. Liam gave away 200% as many magnets as John. John was left with 25% of the magnets he had at first. What fraction of Liam's magnets did he have in the end?
Answer: 6/4x
Then John ended up with v/4 magnets and gave away (3/4)x
Liam gave away 2 ( 3/4)x = 6/4x magnets and was left with x/4 magnets
Notice that they have the same number now so John has 100% of Liam's magnets

for triangle FGH, angles F and G are known, as is the length of side h. Which method should be used to start solving triangle FGH?
- neither law can be used
- law of sines
- law of cosines
- both laws can be used
Answer:
Law of sines
Step-by-step explanation:
i took the test
The law of sines can be used to calculate the side h. Hence, option B is correct.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle termed trigonometry.
For triangle FGH, angles F and G are known, as is the length of side h. The sin angle is the ratio of the perpendicular to the hypotenuse we can calculate one side by using the sine angle.
Hence, Hence, option B is correct.

Stephen spent $12.35 at a food truck. He bought 3 burgers for $1.25 each and 4 corndogs.
How much did Stephen pay for each corndog?
$2.86
$8.60
$2.77
$2.15
Answer:
The 3rd one 2.15
Step-by-step explanation:
12.35 in whole
1.25 x 3 = 3.75
12.35-3.75= 8.60
[tex]\sqrt[4]{8.60}[/tex] = 2.15
pls give brainlist <33
Answer:
$2.15
Step-by-step explanation:
Start off by multiplying $1.25 by 3 to find out how much the burgers are all together. This would be $3.75 for all three of the burgers. Then subtract $3.75 from the total amount spent ($12.35). This would give you $8.60. To find how much he spend on each corndog, you do $8.60 divided by 4. This would give you the answer of $2.15.

Explanation on How to answer what is the density of an object that has a mass of 73,430 and the volume of 7 m3
Answer:
Density = 10,490 g/m³
Step-by-step explanation:
Density = mass ÷ volume
here mass = 73,430 g
volume = 7 m³
density = 73,430 ÷ 7
= 10490 g/m³
Density = 10,490 g/m³
Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?
(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100
Answer:
(x + 4)^2 + (y – 9)^2 = 25
Step-by-step explanation:
The standard form for a circle is
[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex] where (h, k) is the center and r is the radius
In your case, h = -4 and k = 9 and r = 5
So, (x + 4)^2 + (y – 9)^2 = 25
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
Data
h = -4k = 9r = diameter/2 = 10/2 = 5Equation of CircleThe equation of circle is given by
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Let's substitute our values and get our equation
[tex](x--4)^2 + (y-9)^2 = 5^2\\(x+4)^2 + (y-9)^2 = 25[/tex]
we substituted the values of h and k and made sure it's in the standard form of equation of a circle.
The equation for this circle is given as
[tex](x+4)^2 + (y-9)^2 = 25[/tex]
This looks exactly like
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Answer:
x = 25
Step-by-step explanation:
If JK and MN are parallel lines, then ∠JKL = ∠LMN = 61°
By the opposite angle rule, ∠JLK = 39°
In a triangle three angles sum up to 180°
so, ∠JLK + ∠JKL +LJK = 180°
39° + 61° + 3x+ 5 = 180°
3x = 75
x = 25
Step-by-step explanation:
[tex]61 + 39 + 3x + 5 = 180 \\ \\ 105 + 3x = 180 \\ \\ 3x = 180 - 105 \\ \\ 3x = 75 \\ \\ x = 75 \div 3 \\ \\ x = 25 \\ [/tex]
