Answer:

See explanation

Step-by-step explanation:

OK.  Alvi is incorrect because he didn't add the measures of all 3 angles of the triangle, whereas Brian did.  So, Brian is correct and Alvi needs to work on that kind of problem.

Answer:

x<12

Step-by-step explanation:

Hello There!

For this problem we want to isolate the variable using inverse operations

So to get rid of the -3 we add 3 but whatever we do to one side we have to do to the other so we add 3 to both sides

-3+3 cancels out

9+3=12

we're left with

x<12

Answer:

790 units^2

Step-by-step explanation:

Take the area of each side and add them all up. Remember each side is there twice.

Formula: SA = 2(15*5 + 15*16 + 5*16)

SA = 2(75 + 240 + 80)

SA = 2(395)

SA = 790

Question:

The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab

Answer:

[tex]Length = 14a^2b[/tex]

Step-by-step explanation:

Given

[tex]Area = 112a^3b^2[/tex]

[tex]Width = 8ab[/tex]

Required

Determine the height

Area is calculated as:

[tex]Area = Length * Width[/tex]

Make Length the subject

[tex]Length = \frac{Area}{Width}[/tex]

[tex]Length = \frac{112a^3b^2}{8ab}[/tex]

[tex]Length = \frac{14a^3b^2}{ab}[/tex]

Apply law of indices

[tex]Length = 14a^{3-1}b^{2-1}[/tex]

[tex]Length = 14a^2b[/tex]

Answer:

80

Step-by-step explanation:

every triangle adds up to 180 sort of, in this case, turn 4 into 40. 40+20=60 so add 80 to be 180!!!

Answer:

Number of shirts= 6

Step-by-step explanation:

Giving the following information:

The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.

First, we need to calculate the net total price paid  for the shirts:

Net total cost= 77.49 - 3.99= $73.5

Now, the number of shirts bought:

Number of shirts= 73.5 / 12.25

Number of shirts= 6

Answer:

6b+18

Step-by-step explanation:

4×b= 4b

4×3=12

2×b=2b

2×3=6

(combine like terms)

4b+2b=6b

12+6=18

Hope this helped!

The equivalent value of the expression is A = 2b + 10

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 4 + 2 ( b + 3 )

On simplifying the equation , we get

A = 4 + 2b + 6

A = 2b + 10

Hence , the expression is A = 2b + 10

Answer:

The  answer is below

Step-by-step explanation:

Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.

Solution:

The equation for a linear function is given by:

y = mx + b; where m is the slope of the function and b is the y intercept.

Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:

a) x intercept is the value of x when y = 0. Therefore:

0 = 2.5x + 5

2.5x = -5

x = -2

y intercept is the value of y when x = 0. Therefore:

y = 2.5(0) + 5

y = 5

b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.

The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.

Step-by-step explanation:

2 angles are complementary if the sum of their measures is 90°.

a) 90°-55°=35°

The complement is 35°

2 angles are supplementary if the sum of their measures is 180°.

b) 180°-53°=127°

The supplement is 127°

Answer:

1,950 cubic units

Step-by-step explanation:

The computation of the volume of the prism is shown below:

Area of the rectangle = length × breadth

= 10 units × 13 units

=  130 units^2

Now the volume of the prism is

= Base × height

= 130 units × √(17^2 - 8^2)

= 130 units × 15 units

= 1,950 cubic units

Answer:

Answer:

a=8 b=6

Step-by-step explanation:

Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100

so a^2+b^2=100

8^2+6^2=100

64+36=100 ✔

and since A is longer than B, a=8, b=6

Answer: a= [tex]5\sqrt{3}[/tex] b= 5
