Can someone solve for x? And maybe explain it in a simple way?
Answers
Answer:
x=10
Step-by-step explanation:
Because of the two parallel lines, the ratio between the sides must be the same. Since the bottom is 12 to 18 (a ration of two to three) we know that x and x+5 would have the same ratio. Logically, x would have to equal 10 so that x+5 would equal 15 and a ratio of two to three would exist there too. If you go to solve a problem and the answer isn’t obvious, jut set up a ratio.
12/18=x/(x+5)
then cross multiply and solve
12(x+5)=18x
12x+60=18x
60=18x-12x
60=6x
10=x
Answer:
x=10
Step-by-step explanation:
You can set it up as a proportion, since the lines are parallel, the sections are proportionate to each other.
[tex]\frac{x}{12} = \frac{x+5}{18} \\18x=12(x+5)\\18x=12x+60\\6x=60\\x=10[/tex]
The library of a contemporary elementary school is circular. The floor
plan includes sectors reserved for science materials, literary materials,
reference materials, and so on. Find the area of the reference section
excluding its storage area.
The area of the reference section excluding its storage area is
(Round to the nearest hundredth as needed.)
Answers
Answer:
The area of the reference section excluding its storage area is approximately 157.78 square feet.
Step-by-step explanation:
The area of the reference section excluding its storage area ([tex]A[/tex]), in square feet, is the area of the greater circular sector minus the lesser circular sector, that is:
[tex]A = \frac{1}{2}\times \frac{45^{\circ}}{180^{\circ}} \times \pi \times (37.5\,ft)^{2} - \frac{1}{2}\times \frac{45^{\circ}}{180^{\circ}}\times \pi \times (12\,ft)^{2}[/tex]
[tex]A \approx 157.781\,ft^{2}[/tex]
The area of the reference section excluding its storage area is approximately 157.78 square feet.

Answers
Answer:
50
Step-by-step explanation:
The sum of angle on a straight line is 180degres, hence;
X+3+x+20+x+7 = 180
3x+30=180
3x=180-30
3x = 150
X = 150/3
x = 50
Hence the value of x is 50

1/2 of 20 is 10
10 are chocolate
25-(5+10)=25-15=10

What are m21 and m_2?
Answers
Answer:
<1 = 35degrees
<2 = 30degrees
Step-by-step explanation:
Using the theorem that the sum of external angle is equal to sum of interior angle
Considering the smaller triangle
Exterior angle = 115 degrees
Sum of interior = <1 + 80
Equating both
<1 + 80 = 115
<1 = 115 - 80
<1 = 35degrees
For the big rectangle
Exterior angle = 115 degrees
Sum of interior = <2 + 85
Equating both
<2 + 85 = 115
<2 = 115 - 85
<2 = 30degrees

Answer:
Upper left is 9, upper right is 9, lower left is 21
Step-by-step explanation:
They tell us there are 9 birds that are yes fly and yes fish, so that’s the upper right.
They tell us there are 18 yes fish total. Subtract the 9 from the upper right, and that leaves 9 for the upper left.
They tell us there are 39 birds total.
39 - 18 (all fish eaters) - 4 (no fly, no fish) = 17 that can fly but don’t eat fish.
