What are the values of a and b?
Answers
Answer:
D
Step-by-step explanation:
These two triangles are similar triangles. The two angles marked are the same and the two angles at the intersection where you see the square are also the same, making it clear that the last angle must be the same as well.
Therefore,
length 8 from the top triangle is similar to length 6 on the bottom triangle,
length 10 from the top is similar to b on the bottom triangle,
length 6 from the top is similar to a on the bottom.
To find the ratio of similarity, you would compare the length 8 to length 6, and divide them. 8/6 = 1.33333
Now that you've found the proportionality constant, you divide the other two lengths on the top triangle with the constant to get b and a.
b = 10/1.3333 = 7.5
a = 6/1.3333 = 4.5
Therefore, the answer is D: a = 9/2, b = 15/2.

Answers
Answer:
500 (or 5) is in the hundreds place, 30 (or 3) is in the tens place, and 8 is in the ones place.
Step-by-step explanation:
500 is five-hundred, 30 is a ten (10, 20, 30, 40...), and 8 is a one because it is a single digit number and no other numbers come before it, unless it is a decimal.

Tell whether the angles are complementary or supplementary. Then find the value of x
Answers
Answer:
Complementary, x=78
Step-by-step explanation:
90= (x-8)+20
complementary angles add up to 90 degrees.
Answer:
Complementary, x is 78
Step-by-step explanation:
Let's first define what complementary and supplementary angles are. Complementary angles add up to 90 degrees, and supplementary add up to 180. From this image, we can see that this is a right angle. Right angles add up to 90 degrees, therefore, this is a complementary angle.
Now, because we know that it is 90 degrees and that (x-8)+(20) = 90, then we can solve for x. However, if the angle is unknown, then we would do x-8=20. In this case, sense we know for sure this angle is complementary, we do
(x-8)+(20) = 90
X+12=90 We combined like terms
X=78 Inverse operations
You can plug 78 into x and check to see if it is correct if they are 90 degrees total.

A dog is pulling a 15kg sled to the right with a force of 15N. A rhino is pulling the same sled to the left with a force of 42N. There is a frictional force of 5.0N acting on the sled.
Which direction is the friction acting?
What is the Net Force on the sled?
What is the acceleration of the sled?
What is the coefficient of friction on the sled?
Answers
9514 1404 393
Answer:
to the right22 N22/15 ≈ 1.467 m/s²5/147 ≈ 0.034Step-by-step explanation:
a) Friction opposes motion, so is in the opposite direction of the net force on the sled. Taking "left" to be "positive", the two animals are applying a net force of +42 N -15 N = 27 N. That is to the left, so the friction force is to the right.
__
b) The total of forces applied by the animals and friction is ...
27 N -5 N = 22 N . . . to the left
__
c) Acceleration can be found from the relation ...
a = F/m . . . . 'm' is mass
a = (22 N)/(15 kg) = 22/15 m/s² . . . . 'm' is meters
__
d) The coefficient of friction is the ratio of friction force to the normal force on the surface producing the friction. Here, that normal force is the force due to gravity acting on the 15 kg mass of the sled.
coefficient of friction = (5 N)/(9.8 m/s²·15 kg) = 5/147
coefficient of friction ≈ 0.034
Answer:
1. to the right
2. 22 N

Answers
Answer:
4x + 3y = 6 is: y = 3/4x - 3/2

The correct matches are,
4x + 3y = 6 is: y = 3/4x - 3/2

In a sixth grade class the ratio of boys to girls is 4:3 if there are 35 students in the class how many girls are there
Answers
Answer:
The given ratio is 3:4 this means there are 7 people in each unit of this ratio.
It is stated that there are 35 students in total . That would mean that there are
5 Total sets of students in this class . When we multiply the numbers in our starting ratio by this multiple of 5 , our ratio now becomes 15 : 20
15 and 20 do indeed add up to 35 … But , our question wants to know how many more GIRLS are in the class . Boys were calculated to be 15 in number .
Girls were calculated to be 20 in number .
We now know there were 5 more girls than boys in that class ..

total number of student in class=35
let the number of boys be 3x
let the number of girls be 4x
so therefore 3x+4x=35 =>7x=35 =>x=5
so therefore number of boys in class is 3x=>3(5)=15
and number of girls in class is 4x=>4(5)=20
so there are 20–15=5 more girls in class than boys.

What is the constant of proportionality for the relationship of cups of water to minutes?
Answers
Answer:
4 cups every 3 second which means so 80 cuos in one minute
Step-by-step explanation:
hope this helps
The constant of proportionality for the relationship of cups of water to minutes is 80
Represent cups with c and time with t.
So, the given parameter can be represented using the following ratio
c : t = 8 : 6
Multiply by 10
c : t = 80 : 60
60 seconds = 1 minutes.
So, we have:
c : t = 80 : 1
Express as fractions
[tex]\mathbf{\frac ct = \frac{80}1}[/tex]
Multiply both sides by t
[tex]\mathbf{\frac ct = 80}[/tex]
Multiply both sides by 6
[tex]\mathbf{c = 80t}[/tex]
A proportional equation is represented as:
[tex]\mathbf{c= mt}[/tex]
Where m represents the constant of proportionality
By comparison:
[tex]\mathbf{m = 80}[/tex]
Hence, the constant of proportionality is 80
