△XYZ∼△DEF , YZ is 10 meters, ​ XZ ​ is 15 meters, and EF is 8 meters.

What is ​ DF ​?

____ m


Answers

Answer 1

Answer:

The measure of KL is 12 meters.

Step-by-step explanation:

It is given that  △XYZ∼△DEF.

The corresponding sides of two similar triangles are proportional.

[tex]\frac{YZ}{EF}=\frac{XZ}{DF}[/tex]

[tex]\frac{10}{8}=\frac{15}{DF}[/tex]

[tex]10\times DF=15\times 8[/tex]

Divide both sides by 10.

[tex]DF=\frac{120}{10}[/tex]

[tex]DF=12[/tex]

Therefore we can say that if △XYZ∼△DEF, then the measure of DF is 12 meters.

My jar has 25 dimes and some quarters, nickels, and pennies. The number of quarters plus dimes equals the number of pennies. I have 4 nickels for every dime and 2 pennies for every nickel. How many quarters are there? A. 175 B. 150 C. 125 D. 75

Answers

d = dimes = 25
q = quarters
p = pennies
n = nickels
1. q + n = p
2. 4n = 1 d
3. 2p = 1n

1 d = 4n
25 d = x 
x = 4 * 25 = 100 nickels

1 n = 2 p
100 n = x  p
100 n = 200 p

q + n = p
There are 100 nickels. there are 200 pennies
q + 100 = 200
q = 200 - 100
q = 100

Answer
There are 100 quarters,<<<<======


Answer:

Quarters = 175

Step-by-step explanation:

Let the number of dimes in the jar = 25

number of Nickels = n

number of quarters = q

number of pennies = p

Now we will form the equation

Number of quarters plus dimes equal the number of pennies.

q + 25 = p  --------(1)

You have 4 nickles for every dime

n = 4d

n = 4 × 25 = 100

and you have 2 pennies for every nickels

p = 2n

p = 2 × 100 = 200

Now we replace p = 200 in equation (1)

q + 25 = 200

q = 200 - 25

q = 175

Option A. 175 will be the answer.

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5).

Write the equation of this cubic polynomial function.

Recall that the zeroes are (2, 0), (3, 0), and (5, 0). What is the y-intercept of this graph?
-5

The linear factors of the cubic are

Answers

Zeros are the x values which make the function equal to zero. Set it up as you would for a binomial with a constant multiplier "k" to account for the y-intercept (0, -5) given.

f(x) = k(x-2)(x-3)(x-5)

Use the y-intercept (0,-5) to solve for k.

-5 = k(0-2)(0-3)(0-5)
-5 = -30k
-5/-30 = k
1/6 = k


The cubic polynomial function is then ..

f(x) = (1/6)(x-2)(x-3)(x-5)
 

Linear factors are the linear (line) expressions you can factor out of the polynomial. They are (x-2), (x-3) and (x-5).


The cubic polynomial equation which passes through the coordinate (0,-5) and whose zeroes are (2 , 0), (3 , 0), and (5 , 0) is: [tex]y = \dfrac{1}{6}(x-2)(x-3)(x-5)[/tex] and it can be determine by arithmetic operations.

Describe how you would estimate the square root of a number that is not a perfect square without using a calculator. lets say n was the imperfect square number and the square root is w. the square root of n = n+w squared/ 2w.

Answers

To get the square root of imperfect square we can use the formula , which is usually accurate to about two decimal places,
√X =√S +(X-S)2√S
Where, X = the number you want the square roof of, and S is the closest square you know to x.
For example 75 is an imperfect square
Thus, X=75 and thus the nearest number S = 81, this ,means √81 =9.
Putting this into the formula;
√75= 9+(75-81)/2/2(9)
      =  9 + -6/18 
      = 9-0.33333 = 8.667
= 8.667, thus the square root of 75 is 8.66

i need to know the equations

Answers

Let l, t, b represent the numbers of lions, tigers, bears, respectively.

2l +3t +3b = 156 . . . . . . . 156 meals per day are supplied
l +t = 3b . . . . . . . . . . . . . . there are 3 times as many great cats as bears
l +t +b = 68 . . . . . . . . . . . there are a total of 68 animals

_____
The last 2 equations tell you
.. 4b = 68
.. b = 17
Subtracting 3 times the last equation from the first gives
.. -l = -48
There are 48 lions, 3 tigers, and 17 bears.
Let L = number of lions
Let T = number of tigers
Let B = number of bears

If one lion eats 2 meals per day, then L number of lions eat 2L meals per day.
Tigers eat 3T meals per day, and bears eat 3B meals per day.

In one day, all animals combined ate 156 meals.

That gives us our first equation.

2L + 3T + 3B = 156

The lions and tigers are considered great cats. The bears are not cats.
There are 3 times as many great cats as bears.
This gives us our second equation.

L + T = 3B

In all there are 68 animals in the zoo.
From here we get our third equation.

L + T + B = 68

Our system of equations is:

2L + 3T + 3B = 156
L + T = 3B
L + T + B = 68

Now we solve the system of equations.

Subtract the second equation from the third equation.

B = -3B + 68

4B = 68

B = 17

Substitute B = 17 into the first and second equations.

2L + 3T + 3B = 156

2L + 3T + 3(17) = 156

2L + 3T + 51 = 156

2L + 3T = 105      New Equation A

L + T = 3B

L + T = 3(17)

L + T = 51   Equation B

Equations A and B have only two variables, so we can solve them as a system of two equations in two unknowns.

2L + 3T = 105
L + T = 51

Rewrite equation A. Multiply Equation B by -2 and write underneath Equation A. Then add the equations.

       2L + 3T = 105
+    -2L - 2T = -102
-------------------------
                T = 3

Now use B = 17 and T = 3 in the original third equation to solve for L.

L + T + B = 68

L + 3 + 17 = 68

L + 20 = 68

L = 48

Answer: There are 48 lions, 3 tigers, and 17 bears

Check:
"Lions eat 2 meals per day, tigers and bears eat 3 meals each per day."
Number of meals:
2 * 48 + 3 * 3 + 3 * 17 = 96 + 9 + 51 = 156

"There are 3 times as many great cats in the zoo as bears."
48 + 3 = 51, and 51 is 3 times 17

"There are 68 animals in the zoo."
48 + 3 + 17 = 68

All statements are satisfied by our solution, so the answer above is correct.

Answer:

Option (c) is correct.

He pays $ 2652.

Step-by-step explanation:

Given :   Nial is signing a lease for an apartment that rents for $1020/month.

We have to find the amount he pay to move in if he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.

Since, given he must pay the first and last months' rent and a security deposit equal to 60% of his monthly rent.

Given monthly rent is $ 1020

That is 60% of his monthly rent = [tex]\frac{60}{100}\times 1020=612[/tex]

Thus, total amount he needs to pay is  first month rent + last month rent + 60% of his monthly rent.

That is 1020 + 1020 + 612 = 2652.

Thus, He pays $ 2652.

In a hockey club there are 5% more boys than there are girls. If there is a total of
246 members in the club, what is the number of boys and the number of girls?
HOW WOULD I WORK THIS OUT

Answers

Determine the percentage of boys and the percentage of girls in the club.
For an instance, pb stands for percentage of boys, and pg stands for percentage of girls.
pb + pg = 100%

There are 5% more boys, pb = pg + 5%
Input to the previous equation to find the percentage of the girls
pb + pg = 100%
pg + 5% + pg = 100%
2pg + 5% = 100%
2pg = 100% - 5%
2pg = 95%
--------------- divide each side by 2
pg = 47.5%

Substitute the percentage of girls to either equations to find the percentage of the boys
pb = pg + 5%
pb = 47.5% + 5%
pb = 52.5%

Find the number of the boys and the girls
The boys
b = pb × total members
b = 52.5% × 246
b = 0.525 × 246
b = 129.15
Because the number of people couldn't be a fraction, round to the nearest whole number
b = 129

The girls
g = total - b
g = 246 - 129
g = 117

There are 129 of boys, and 117 of girls

The number of boys and the number of girls are 126 and 120 respectively.

What is percentage?

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.

Given that, there are 5% more boys than there are girls, there is a total of

246 members in the club,

We need to find the number of boys and the number of girls,

Here we will use the concept of percentage as well as equation solving,

Let the number of girls be x, so, the number of boys = 105% of x = 1.05x

According to the question,

x+1.05x = 246

2.05 x = 246

x = 120

1.05x = 126

Hence, the number of boys and the number of girls are 126 and 120 respectively.

B)  ∠AFB and ∠CFD are neither.  Vertical angles are also known as vertically opposite angles.  While these two only share a vertex, they are not opposite each other.  They also do not form a linear pair, as they do not form a straight line.
C)  ∠BFD and ∠AFE are vertical angles.  They are opposite each other and share only a vertex.

Answer:

Linear Pair, Neither, Vertical.
