What is the measure of the smallest angle in the right triangle below?
(2x)
(x + 6)°
28°
56°
34°
12°
Answer:
34°
Step-by-step explanation:
If we assume that the acute angles in the triangle are 2x and (x+6), then we have ...
2x +(x +6) = 90
3x +6 = 90 . . . . . . simplify
x + 2 = 30 . . . . . . . divide by 3
x = 28 . . . . . . . . . . subtract 2
Then the angles are ...
2x = 2(28) = 56
x+6 = 28+6 = 34
The smallest angle is 34°.

in a class of 32 students the mean height of the 14 boys is 1.56 metres the mean height of the 32 students is 1.515 metres work out the mean height of the girls show your working out
Answer:
1.515 = 14* 1.56 + 18*x/(32)
0r, 18x= 1.515*32 - 14*1.56
or, 18x= 26.64
x= 1.48
Step-by-step explanation:
Answer:
mean height of girls = 1.48 m
Step-by-step explanation:
Find the sum height of 32 students.
Sum of the height of 32 students = 32 * mean of 32 students
= 32 * 1.515
= 48.48 m
Sum of the height of 14 boys = 14 * mean of 14 boys
= 14 * 1.56
= 21.84
Number of girls = 32 - 14 = 18
Sum of the height of 18 girls = 48.48 - 21.84 = 26.64 m
Average of the height of 18 girls = 26.64 ÷ 18
= 1.48 m
The perimeter of a rectangle is 234 meters.
The rectangle is twice as long as it is wide.
What are its length and width?
I am going to show you how easy this is. Once you understand, you will be able to do this forever.
:
Assuming the side of the rectangle are (L) length and (W) width, the perimeter:
2L + 2W = 234
:
"the rectangle is twice as long as it is wide,", the equation for this statement:
L = 2W
:
In the first equation, we can replace L with 2W, then we have
2(2W) + 2W = 234
4W + 2W = 234
6W = 234
Divide both sides by 6
W = 234%2F6
W = 39 meters is the width
:
Remember it said the length is twice the width, therefore:
L = 2(39)
L = 78 meters is the length
:
:
Check this by finding the perimeter with these values
2(78) + 2(39) =
156 + 78 = 234
IMPORTANT PLEASE I NEED NOW:Find the area of each face of the cube whose volume is 729 cm
Answer:
81
Step-by-step explanation:
square root of 729= 9
9×9=81
Answer:
Step-by-step explanation:
Formula of Volume= [tex]a^{3}[/tex] - a = side
Therefore since the volume is given you just need to find the side.
729=[tex]a^{3}[/tex] = [tex]\sqrt[3]{729}[/tex] = a
= 9 = a
Now you know that 9 is the side, so using that find the area of one face-
Area of a square= 9 x 9 = 81[tex]cm^{2}[/tex]
How do you write 27 in standard form?
Please can you give more different examples and explanation detail so I will understand.Please guys help...
Answer:
Cardinal: twenty seven
Ordinal: twenty seventh
Step-by-step explanation:
hope this helps!!!!!!
Answer:
2.7×10
Step-by-step explanation:
Basically the number 27 has to be in between the numbers 0 and 10.
So to do that you have to divide 27 by 10 until it is between 0 and 10 which is then 2. 7,
And to get the 10 you have to count how many times you had to divide 27 by 10 to get which is 1 so you leave it as ten so the answer you get is
2.7 x 10

4(5n -7) =10+2 i need step by step explanation i dont get it
Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)

The slope of the line will be equal to 1.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The slope of the line will be calculated by using the formula below:-
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The given points are:-
Choose (x1, y1)
X₁= 2 y₁= -5
Identify (x2, y2)
X₂= 7 y₂= 1
Apply the slope formula:-
m= ( y₂ - y₁ ) / ( x₂ - x₁ )
m= 1-(-5)/7-2.
m= ( 5 / 5 )
m = 1
Therefore, the slope of the line will be equal to 1.

5x-5<5(x-4) true, never true, or sometimes true?
Answer: never true
Step-by-step explanation:
What is the value of x in the equation: 3 (4x - 1) - 3x = - (x + 2)?
Give your final answer in Decimal form.
Solution:
[tex]-0.5[/tex]
Steps:
[tex](4x - 1) - 3x = - (x + 2)[/tex]
Start with the left side and combine like terms
[tex]4x-1-3x=-(x+2)\\[/tex]
Combine [tex]4x[/tex] and [tex]-3x[/tex]. After doing this, you would have [tex]x[/tex] because 4-3 = 1
[tex]x-1 =-(x+2)[/tex]
Then, you can distribute the negative on the right side
[tex]-(x+2) = -(x)+-(2) = -x-2[/tex]
You would end up with
[tex]x-1=-x-2[/tex]
Add x to each side.
[tex]2x-1=-2[/tex]
Add 1 to each side
[tex]2x=-1[/tex]
Divide each side by 2 to simplify.
[tex]x=-1/2\\x = -0.5[/tex]

Ronnie wants to buy a computer table that measures 10 feet by 17 feet. The cost of the table is $16 per square foot. How much will it cost Ronnie to buy the computer table for his study room?
Answer:
Pongamos los datos
supongamos que la sala costo x
si la sala costo x, el comedor costo el doble, osea 2x
luego dice que la sala costo el triple de la mesa, si la sala costo x, la mesa costo x/3
ahora reemplazamos: dice que todo costo 35000
x + 2x + x/3 = 35000
3x/3 + 6x/3 + x/3 = 35000
10x/3 = 35000
10x= 105000
x = 10500
reemplazamos todos los datos
la sala costo x, entonces la sala costo 10500
el comedor costo 2x, entonces 2(10500) = 21000
la mesa costo x/3, entonces 10500/3 = 3500

A plumber has 8 9/10 feet of rubber tubing to make 2 rubber pipes. He will use3 1/12 feet of tubing to make each pipe. The plumber says he will have about 3 feet of rubber tubing after he makes the pipes. Is his statement reasonable?
Answer:the answer is D
Step-by-step explanation:
This is reasonable because feet can be rounded to 9 feet and feet can be rounded to 3 feet. Since 9 - 2(3) = 3, the plumber will have about 3 feet of rubber tubing left. its true make sure you read the answer to make sure bc they can mix them up LOL

Investigate the range of each parent function below over the interval o
ranges from least to greatest.
Identity function, reciprocal function, quadratic function, cubic function, square root function
Answer:
Here we have the domain:
D = 0 < x < 1
And we want to find the range in that domain for:
1) y = f(x) = x
First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)
f(0) = 0 is the minimum in the range.
f(1) = 1 is the maximum in the range.
The range is:
0 < y < 1.
2) y = f(x) = 1/x.
In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.
f(0) = 1/0 ---> ∞
f(1) = 1/1
Then the range is:
1 < x.
Notice that we do not have an upper bound.
3) y = f(x) = x^2
This function is strictly increasing, then:
f(0) = 0^2 = 0
f(1) = 1^2 = 1
the range is:
0 < y < 1
4) y = f(x) = x^3
This function is strictly increasing in the interval, then:
f(0) = 0^3 = 0
f(1) = 1^3 = 1
the range is:
0 < y < 1.
5) y = f(x) = √x
This function is well defined in the positive reals, and is strictly increasing in our domain, then:
f(0) = √0 = 0
f(1) = √1 =1
The range is:
0 < y < 1
Solve for x the triangles are similar
Answer:
x = 13
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{DC}{DU}[/tex] = [tex]\frac{CB}{UT}[/tex] , substitute values
[tex]\frac{11x-13}{60}[/tex] = [tex]\frac{169}{78}[/tex] ( cross- multiply )
78(11x - 13) = 10140 ( divide both sides by 78 )
11x - 13 = 130 ( add 13 to both sides )
11x = 143 ( divide both sides by 11 )
x = 13
