PLEASE HELP::::::: Triangle PQR has medians QM and PN that intersect at Z. If ZM= 4, find QZ and QM
HELP HELP
Answer:
value of QZ = 8 units and QM = 12 units.
Step-by-step explanation:
Given: In triangle PQR has medians QM and PN that intersect at Z.
If ZM = 4 units.
In the figure given below; second median divided the two triangles formed by the first median in the ratio 2:1.
We have to find the value of QZ and QM;
QZ:ZM = 2: 1
⇒
Substitute the value of ZM =4 units and solve for QZ;
Multiply both sides by 4 we get;
Now, calculate QM;
QM = QZ+ZM = 8 + 4 = 12 units.
Therefore, the value of QZ and QM are; 8 units and 12 units
One month, Ruby worked 6 hours more than Isaac, and Svetlana worked 4 times as many hours as Ruby. Together they worked 126 hours. Find the number of hours each person worked.
Answer/Step-by-step explanation:
Let x hours be the number of hours Issac worked
x+6 hours be the number of hours Ruby worked
4(x+6) hours be the number of hours Svetlana worked.
x + x + 6 + 4(x+6) = 126
x + x + 6 + 4x +24 = 126
6x +30 = 126
6x = 96
x = 16
Therefore, Issac worked 16 hours.
Ruby worked 16+6 = 22 hours
Svetlana worked 22 × 4 = 88 hours.
If helpful, please mark as brainliest! =)
Answer: Ruby: 22 hours, Isaac: 16 hours & Svetlana: 88 hours.
Step-by-step explanation:
Let's begin by assigning letters to represent our unknowns:
R (hours Ruby worked)
I (hours Isaac worked)
S (hours Svetlana worked)
Now let's see if we can express all three unknowns in terms of one unknown, according to the facts given in the problem:
R = I + 6 (Ruby worked 6 more hours than Isaac)
S = 4R (Svetlana worked 4 times more hours than Ruby)
We can see that we can express the hours Isaac worked in terms of Ruby:
R = I + 6, therefore, I = R - 6
Now we have all three unknowns expressed in terms of one unknown (R). Now we can write an equation to express the given sum of their worked hours (126) in terms of our expressions for one unknown (R):
R + (R - 6) + 4R =126
Now let's solve our equation for the value of R and then use our expressions for R to calculate the values for I and S:
R + R - 6 + 4R = 126
6R - 6 = 126
6R = 126 + 6
6R = 132
R = 132/6
R = 22 (hours Ruby worked)
I = R - 6
I = 22 - 6
I = 16 (hours Isaac worked)
S = 4R
S = 4(22)
S = 88 (hours Svetlana worked)

A box is made of wood with its external dimensions of 154 cm x 100 cm x 84 cm and thickness of 2 cm.
How much wood was used to make it?
Answer:
Step-by-step explanation:
volume of 154×100×84 box = 1,293,600 cm³
dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80
volume of airspace = 150×96×80 = 1,152,000 cm³
volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³
a person got 10percent increase in his salary . If his salary was Rs50000 then find increase in salary
Answer:

Divide by 3, divide by 3 again. 37 is a prime number, so it can't be divided again after that.
A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that represents the height y(in inches) of the plant after x months.
Answer:
y = 3 + 2x
Step-by-step explanation:
In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.
y = 3 + 2x
which value of x satisfies the equation below? 4x-7+25
Answer: =4x+18

Work out the value of x when y=5
Answer:
0.0000000164
Step-by-step explanation:
x= 4y^-12
for,
y = 5
x = 4×5^-12
x = 4/5^12
x = 4/244,140,625
x = 0.0000000164

What is the solution of the following system? Use the substitution method.
y – 2x = 8
16 + 4x = 2y
O The only solution is (24, 0).
O The only solution is (1, 10).
○There is no solution.
O There are an infinite number of solutions.
Answer:
y-2x=8 (label equation 1)
16+4x=2y (label equation 2)
divide equation 2 by 2 to find y
y=2x+8
sub this in equation 1
(2x+8)-2x=8
2x+8-2x=8
8=8
once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

Eions?
What is the solution to the system of equations
Answer:
(2, - 5 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 1 → (1)
4x + y = 3 → (2)
Substitute y = - 3x + 1 into (2)
4x - 3x + 1 = 3
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = - 3(2) + 1 = - 6 + 1 = - 5
solution is (2, - 5 )

step 1 is wrong . The 1st step should be 15² - 9² = c² .
Answer: step A
Step-by-step explanation:
The Pythagorean theorem is a^2+b^2=c^2, where c is always the hypotenuse (the longest side of the triangle). Step A is written as 9^2(thats the a value squared)+15^2(which is the hypotenuse value squared)=c^2. It should be: 9^2+b^2=15^2
