What is expression?

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ √40/√8

Factor of √40 = √8×√5

⇒ (√8√5)/√8

Cancel out of√8

⇒ √5

Hence, the quotient of expression of √40/√8 is √5.

Fifty students were eating lunch in the school cafeteria. The ratio of boys to girls was 25:25. Mrs. White asked Kym to explain what that ratio meant. Kym said it meant that 25% of the students in the cafeteria were boys.


Explain why Kym is incorrect.

Kym is wrong because instead of 25% it would be 50 percent

Step-by-step explanation:

Answer:

Sample Response: The ratio of boys to total students was 25:50. Written as a fraction, this is 25/50. Rewrite the fraction with a denominator of 100 to 50/100. So 50% of the students were boys.

Help please!!! Find the measure of A in the picture below.

Answers

Answer:

Step-by-step explanation:

If you draw in BD, you can show that triangle BCD = triangle BAD by SSS

That means that <A = <C  parts of congruent parts are congruent.

<A + <C + 115 + 71 = 360

<A + <C + 186 = 360            All convex quadrilaterals have  4 interior angles that add to  360 degrees

<A + <C = 360 - 186

<A + <C = 174

So call <A  and < C = x

x + x = 174

2x = 174

x = 174 / 2

x = 87

<A = 87

help!! i don’t understand geometry

Answers

I basically solved for x first.
42+43x+1=180
X=3.2 rounded

Next plug in the value of x into the EDC equation
43(3.2)+1=138.6

Then add it to the measure of EDN
138.6+42= 180.6

So the answer is measure of NDC= 138.6

explanation i learned it in 5th grade lol

The size of the angle x is 13°

What is a triangle?

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

From the figure,

Let the triangle having ∠x have the following angles:

∠A and ∠B.

Now,

∠A is opposite to 85°.

So,

∠A = 85°

98° and one angle are corresponding angles.

So,

One angle = 98°

Now,

One angle and ∠B is a straight angle.

So,

∠B + 98 = 180

∠B = 180 - 98

∠B = 82°

Now,

The sum of the triangle is 180.

This means,

x + 82 + 85 = 180

x = 180 - 167

x = 13

Thus,

The value of x is 13.
