Hey there!

ANSWER: [tex]\frac{23}{20}[/tex]

EXPLANATION:

To find the answer to your question, you will need to add.

[tex]\frac{3}{4}+\frac{2}{5}[/tex]

First, multiply the denominator.

[tex]5*4=20[/tex]

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

[tex]5*3=15[/tex]

Now multiply 4 bu 2.

[tex]4*2=8[/tex]

If you want to get the numerator, add what you got after multiply.

[tex]15+8=23[/tex]

The numerator is 23. So now let's complete the fraction.

[tex]\frac{23}{20}[/tex]

This is your answer!

Hope this helps!

Answer: 868 miles

Step-by-step explanation:

Given: The scale from a map to actual distance is 2.5 cm to 620 miles.

i.e. 1 cm on map  = [tex]\dfrac{620}{2.5}\text{ miles}=248 \text{ miles}[/tex]

If the distance on the map between Chicago and Boston is about 3.5 cm.

Then, the actual distance between them =  [tex]3.5\times 248 \text{ miles}=868 \text{ miles}[/tex]

Hence, the approximate distance between Chicago and Boston = 868 miles.

Multiply both sides by -1 (Flip the signs and symbol):

[tex]\left(-2a\right)\left(-1\right)<6\left(-1\right)[/tex]

[tex]2a<-6[/tex]

Divide both sides by 2:

The discriminant of the given quadratic equation is 8.

The discriminant determines the type and number of solutions that the equation has.

If the discriminant is positive, the equation has two distinct real solutions. If the discriminant is zero, the equation has one repeated real solution. If the discriminant is negative, the equation has no real solutions.

Given is a quadratic equation -x²+4x-2 = 0, we need to find the discriminant of the quadratic equation,

So,

D = b²-4ac

Here,

a = -1, b = 4 and c = -2

Therefore,

D = 4² - 4(-1)(-2)

D = 16 - 8

D = 8

Hence, the discriminant of the given quadratic equation is 8.

Answer:

(1, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

let (x₁, y₁ ) = (3, 9) and (x₂, y₂ ) = (- 1, - 5) then

midpoint = ( [tex]\frac{3-1}{2}[/tex] , [tex]\frac{9-5}{2}[/tex] ) = (1, 2 )

Answer:

(1,2)

Step-by-step explanation:

use the equation

(x,y) midpoint = ( x1 + x2/ 2), (y1 + y2 / 2 ) )

Answer:

It would be D

Answer:

B

Step-by-step explanation:

So we are trying to find the number that is not between [tex]\frac{\sqrt{16}}{2}[/tex] and 3π on the number line. To do this, lets try to find roughly (exactly if possible) that [tex]\frac{\sqrt{16}}{2}[/tex] and 3π are. Lets start with [tex]\frac{\sqrt{16}}{2}[/tex].

[tex]\frac{\sqrt{16}}{2}=\frac{4}{2}=2[/tex]

So now, by looking at the number line, we can see that the values must be greater than 2. Now lets find 3π. Lets use 3.14 for π (3.14 is actually smaller than the actual value of π):

3(3.14) = 9.42

So we know that the value must be less than 9.42.

We can rewrite answer choice A as 2.08, with is more than 2 and less than 9.42. Therefore, it is between the two numbers on the number line.

While I do not know the exact value of √0.4, I know that it will be less than 1, making it less than 2. Therefore, it is not between the two numbers on the number line, and therefore is our answer.

Lets go through the other two answer choices though.

For C, while 9.37 is close to 9.42, it is still less than 9.42 and greater than 2, and therefore is between the two numbers on the number line.

For D, √9 can be rewritten as 3, which is between the two numbers on the number line.

Even if you did not know that answer choice B, √0.4, was less than 1, you still would have been able to find that B was the correct answer by the process of elimination.

I hope you find my answer helpful.

Step-by-step explanation:

Square Root of 38 to the nearest tenth, means to calculate the square root of 38 where the answer should only have one number after the decimal point.

Here are step-by-step instructions for how to get the square root of 38 to the nearest tenth:

Step 1: Calculate

We calculate the square root of 38 to be:

√38 = 6.16441400296898

Step 2: Reduce

Reduce the tail of the answer above to two numbers after the decimal point:

6.16

Step 3: Round

Round 6.16 so you only have one digit after the decimal point to get the answer:

6.2

To check that the answer is correct, use your calculator to confirm that 6.22 is about 38.

Answer:

6

Step-by-step explanation:

2x+4=16

2x=12

x=6

Answer: x = 6

Step-by-step explanation: To solve for x, we must first

isolate the term containing x, which in this problem is 2x.

Since 4 is being added to 2x, we subtract 4

from both sides of the equation to isolate the 2x.

On the left, the +4 and -4 cancels

out and on the right, 16 - 4 is 12.

So we have 2x = 12.

Then just divide both sides by 2 so x = 6.

Step-by-step explanation:

Use PEMDAS

It says Parentheses first.

4*b, 4*(-2)= 4b, -8

2*5, 2*-b= 10, -2b.

Write the equation out:

4b-8=10-2b

Add 8 to both sides

4b=18-2b

Add 2b on both sides

6b=18

Divide both sides by 6

b=3
