1). What is the perimeter of the triangle?
с
5 mm
12 mm
Answer:
30
Explanation:
To begin, first find the length of the third side of the triangle. We are given that the two short sides of the triangle have lengths of 5 and 12. Use the Pythagorean Theorem to find the length of the third side:
a2+b2=c2,
where a and b represent the two shorter sides of the triangle, and c is the hypotenuse:
a2+b2=c2
52+122=c2
25+144=c2
169=c2
169−−−√=c2−−√
c=13
Now that we have the lengths of all three sides, add them together to find the perimeter:
5+12+13=30
The perimeter of the triangle is 30.
Which of the methods can be you to solve -2/3c=16
Answer:
C. Divide each side by -2/3
Step-by-step explanation:
-2/3 is being multiplied by c. So we have to do the inverse of multiplication which is division.

lmk if it is right
Answer:
Step-by-step explanation:
In rectangle, diagonals bisect each other and diagonals are equal.
So, AE = DE
∠ADE = ∠DAE {Angles opposite to equal sides are equal}
6x - 1 = 2x + 15
6x = 2x + 15 + 1
6x = 2x + 16
6x -2x = 16
4x = 16
x = 16/4
x = 4
∠ADE = 6x - 1
= 6*4 - 1
= 24 - 1
= 23

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2
Answer:
A) 12-10
B)36+225
Step-by-step explanation:
A) 3x4=12, 5x2= 10= 12-10
B) 3x2=6x6=36, 3x5=15x15=225=36+225
For x = 3 and y = 5 the values of the given expressions are (a) 4x - 2y = 2 and (b) 2x² + 3y² = 93.
What is substitution?Substitution is a mathemaical technique for replacing variables with specific or covnient values according to the context.
When the values of variables are given to solve an equation we just have to replace those numerical values in place of the given variables.
Given, x = 3 and y = 5.
∴ 4x - 2y is,
= 4(3) - 2(5).
= 12 - 10.
= 2.
And
2x² + 3y².
= 2(3²) + 3(5²).
= 2(9) + 3(25).
= 18 + 75.
= 93.

An average clementine is shaped like a sphere and has a diameter of 3.5 inches. What is the volume of the fruit? Use 3.14 for pi. Round your answer to the nearest hundredth. (4 points) a 20.45 cubic inches b 21.34 cubic inches c 22.44 cubic inches d 23.78 cubic inches
Answer:
The volume is 22.44 cubic inches
Step-by-step explanation:
The formula for the volume of a sphere is
We know the diameter, but we can easily convert this into the radius by dividing it by 2, since the diameter is twice as long as the radius.
3.5/2 = 1.75
Now we can find the volume.
So, the average volume of a clementine is 22.46 cubic inches
The closest option you have is 22.44 so if you round it that should be your answer.
Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At sunset, the temperature was -5 degrees Fahrenheit. How many hours will it take for the temperature to reach -19° F?
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
[tex]-5+x(-2)=-19[/tex]
Where we taking 2 negative because temperature decreases.
[tex]-5-2x=-19[/tex]
[tex]-5+19=2x[/tex]
[tex]14=2x[/tex]
[tex]x=\frac{14}{2}[/tex]
[tex]x=7[/tex]
Hence, it will take 7 hours for the temperature to reach -19° F.

Which equation shows the relationship 30% of 140 is x?
Answer:
Step-by-step explanation:
[tex]equation: \frac{x}{140} = \frac{30}{100} \\reduced: 100x = 4200\\ solved: \frac{100x}{100} = \frac{4200}{100} \\x = 42[/tex]
An equation is formed of two equal expressions. The equation that shows the relationship 30% of 140 is x is x=0.30×140.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that 30% of 140 is equal to x. Therefore, we can write,
[tex]\text{30\% of 140} = x\\\\\dfrac{30}{100} \times 140 = x\\\\x = 0.30 \times 140\\\\x=42[/tex]
Hence, the equation that shows the relationship 30% of 140 is x is x=0.30×140.
