How Can I Solve This Problem

Answers

Answer 1

Step-by-step explanation:

first find x

2x+15=6x-1

15+1=6x-2x

16=4x

x=4

then find the value of the angle

6(4)-1=23

lmk if it is right

Answer 2

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

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

Answers

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.

If x = 3 and y = 5, work out the value of a) 4x - 2y
b) 2x2 + 3y2

Answers

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.

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?​

Answers

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]

Which equation shows the relationship 30% of 140 is x?

Answers

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.

1). What is the perimeter of the triangle?
с
5 mm
12 mm

Answers

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.
