Answer:
51°
Step-by-step explanation:
The angles where the expressions are given are a linear pair, so total 180°.
(3x +15) +(10x +9) = 180
13x = 156 . . . . . . . . . . . . . . . subtract 24, collect terms
x = 156/13 = 12
Then the acute angle is ...
3x +15 = 3(12) +15 = 36 +15 = 51
The stairs make an angle of 51° with the basement floor.
_____
Additional comment
Building code requires the rise to be not more than 8 and the run not less than 9, so the maximum angle is about 41.6°. A 51° staircase would not meet code.

A positive angle less than 360 that is coterminal with -725 degrees is
The positive angle is less than 360 which is coterminal with -725 degrees is 85 degrees.
What are Coterminal Angles?Coterminal angles are those with the same beginning side and the same terminal sides. These angles are in the typical position, although their values differ. They have the same sides, are in the same quadrant, and their vertices are identical. The endpoint sides coincide at the same angle when the angles are rotated clockwise or anticlockwise.
An angle that is coterminal with -725 degrees is an angle that has the same initial and terminal sides as -725 degrees, but its measure is between 0 and 360 degrees.
To determine a positive angle less than 360 that is coterminal with -725 degrees, we can add or subtract multiples of 360 from -725 degrees until we get an angle within that range.
In this case, -725 degrees - (2 x 360) = -725-720= -1445.
So, the positive angle less than 360 that is coterminal with -725 degrees is -1445 degrees + 360 = 85 degrees.

How do I put 4/3 on a fraction number line
Answer:
you would put it as four thirds
Step-by-step explanation:
Answer:
Lets break this down.
4/3 can be simplified as 3/3 and 1/3.
3/3 can also be simplified into 1.
That leaves us with a mixed fraction as 1 1/3.
Now that we know our mixed fraction, we must locate this on a number line.
I drew 3 marks on a number line to demonstrate this, along with a indicator showing where 1 1/3 is.
Since 1 1/3 has one whole, we know that 1 1/3 is greater than 3/3.
We locate 1 on the number line, which is directly in the middle.
Now, we have to move one more to the right, since we have a remaining 1/3.
This leaves us where we are on the photo provided.

find the area of the triangle
answer in digital format only
Answer:
33
Step-by-step explanation:
Assume that each cell on the grid represents one unit. One can use the formula, ([tex]A=\frac{(base)(hieght)}{2}[/tex]) to find the area of the triangle. One can see that the base of the triangle is, (11), and the height is (6). Substitute in the given values and solve for the area,
[tex]A=\frac{(11)*(6)}{2}[/tex]
[tex]A=\frac{66}{2}[/tex]
[tex]A=33[/tex]

Answer:
1/9 i think not sure
Step-by-step explanation:
Answer:
1/9
Step-by-step explanation:
Well the chance of picking 3 one time is 1/3
The chance of picking 3 the second time is 1/3
So at first, we've succeeded with probability 1/3 and failed with probability 2/3
We don't care what happens next if we've failed - we already failed.
So we've reached the "picking the second card with hope in our hearts" 1/3 of the time and we again succeed with 1/3 of a chance, so the total probability of success is 1/3 * 1/3 = 1/9
Think of the options:
3 and 3 - probability 1/3 * 1/3 = 1/9
3 and non-3 - probability 1/3 * 2/3 = 2/9
non-3 and 3 - probability 2/3 * 1/3 = 2/9
non-3 and non-3 - probability 2/3 * 2/3 = 4/9
Note that all the options sum to 1 - as probabilities of all options always should.
Find the value for x and y if x+(xy)^1/2+y=14 and x^2+xy+y^2=84
Answer:
[tex]xy = 4 [/tex]
Step-by-step explanation:
Taking the first equation , we have ,
[tex]\implies x + (xy)^{\frac{1}{2}} + y = 14 \\\\\implies x + \sqrt{xy}+ y = 14 \\\\\implies x + y = 14 -\sqrt{xy}\\\\\implies (x+y)^2 = (14-\sqrt{xy})^2 \\\\\implies x^2+y^2+2xy = 196 + xy -28\sqrt{xy} \\\\\implies x^2+y^2+xy = 196 - 28\sqrt{xy}[/tex]
Now according to second equation,
[tex]\\\\\implies 84 = x^2+xy+y^2 [/tex]
Plug on this value ,
[tex]\implies 84 = 196 -28\sqrt{xy}\\\\\implies -112 = -28\sqrt{xy}\\\\\implies \sqrt{xy}=\dfrac{112}{28}\\\\\implies \boxed{\boxed{ xy = 16 }}[/tex]
On substituting this value in terms of one variable of the equation you can get the values of x and y .

Answer:
Z = 80 degrees and X = 8 degrees
Step-by-step explanation:
The reason Z = 80 degrees is because a flat line always has a measure of 180 degrees.
I forget the term, but we know that 6x + 52 is equal to 100 due to some angle theorem. (Once again, I do not remember the term.)
We then subtract 52 from 100 to get the equation 6x = 48. Divide them both by 6 and you get X = 8!

Answer:
336 m squared
Step-by-step explanation:
To do this we can first find the area of one face of the prism and multiply it by all the other triangular faces
(4*12)*4=192
then can find the area of the square underneath
12*12=144
then add them together
192+144=226

a bakery place the following price for bagels one bagel for $1.50 two bagels for$2.25 a half a dozen for
$6.50 a dozen for $12 is the price per bagel proportion 2 the number of bagels brought.
Answer:
no
Step-by-step explanation:
1 bagel $1.50 ---------> unit cost: $1.50/bagel
2 bagels $2.25
6 bagels $6.50
12 bagels $12 ---------> unit cost: $1/bagel
Since the unit costs are not equal, the prices are not proportional.

Answer:
Exact Form:
17/15
Decimal Form:
1.1333333.....
Mixed Number Form:
1 2/15
Answer:
17 / 15
Step-by-step explanation:
LCM of 3 and 5 is 15.
4 / 5
= ( 4 / 5 ) x ( 3 / 3 )
= 12 / 15
1 / 3
= ( 1 / 3 ) x ( 5 / 5 )
= 5 / 15
( 4 / 5 ) + ( 1 / 3 )
= ( 12 / 15 ) + ( 5 / 15 )
= ( 12 + 5 ) / 15
= 17 / 15

Yvonne wants to cover the back of her smartphone with a decorative pattern. If the phone's length is 1/2 foot and width is 1/6 foot, what is the area that the decorative pattern will cover?
Answer:
1/12 square foot
Step-by-step explanation:
Area of the pattern = LEngth * Width
Given the following
Length = 1/2 foot
Width = 1/6 foot
Area of the pattern = 1/2 * 1/6
Area of the pattern =1/12 square foot
Hence the area that the decorative pattern will cover will be 1/12 square foot
