Answer:

x + 37 = 90

Step-by-step explanation:

Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.

Step-by-step explanation:

15y + 12x = 18

5y + 4x = 6

The  second equations is the first times 3 so they are basically the same.

Infinite Solutions.

2x+ 3y= 12

-6y= 4x-24          Rearranging the second equation:

-4x - 6y = -24      Multiplying the first equation by 2:

4x + 6y = 24      

- we see that the last equation is -1 * previous equation.

So there are infinite solutions.

Step-by-step explanation:

g(0)= 1

g(5)= 1-3/20 = 17/20

-5.g(4)-1 =-5. (13/16) -1 = -65/16 -1= (-65-16)/16= -81/16

Answer:

When c and a are positive or both are negative

Step-by-step explanation:

negative times negative equals positive so if a was negative and c was negative -a*-c= ac

Of course positive times positive equals negative so if a and c were positive we could do

a*c= ac

Answer: The level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Step-by-step explanation:

If the amount is decreasing by r%, then the final amount is given by :-

[tex]A=P(1-r)^t[/tex]

, where P = initial value , t= time

Given: P= 200 milligram, r= 35% = 0.35, t= 4 hours

The level of aspirin (mg) will be in your bloodstream in 4 hours = [tex]200(1-0.35)^4[/tex]

[tex]=200(0.65)^4\\\\=200\times 0.17850625\\\\=35.70125\approx35.70 \ mg[/tex]

Hence, the level of aspirin (mg) will be in your bloodstream in 4 hours = 35.70 mg.

Answer:

8 shirts

Step-by-step explanation:

Given the equation a = 3b, where

a = the number of shirts  Wanda has

b = the number of shirts Wanda's brother (Will) has

Hence if Wanda has 24 shirts then

24 = 3b

Divide both sides by 3

24/3 = b

b = 8 shirts

Will has 8 shirts.

Answer:

8 shirts

Step-by-step explanation:

Find the value of each number in a logarithm table:

log 0.3452 = -0.4619

log98.56 = 1.9937

log0.06541 = -1.1844

log451 = 2.6542

Add the top two together, then the bottom two:

Top two: -0.4619 + 1.9937 = 1.5318

Bottom two: -1.1844 + 2.6542 = 1.4698

Now subtract the sum of the bottom from the sum of the top:

1.5318 - 1.4698 = 0.062

Now find the antilog:

10^(0.062)

Answer = 1.1535

Answer:

d

Step-by-step explanation:

Eli is incorrect because he added the exponents even though the bases are not the same.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

[tex]6^5[/tex] x [tex]5^{-3}[/tex] = 6²

Now,

Simplifying the expression.

= [tex]6^5 \times 5^{-3}[/tex]

= [tex]\frac{6^5}{5^3}[/tex]

We see that,

6² is when we add the exponents even if the base is not the same.

We can not add the exponent if the base is not the same.

Thus,

Eli is incorrect because he added the exponents even though the bases are not the same.

Answer:

Below in bold.

Step-by-step explanation:

5x - 3y = 1

3x- y = 5                    Multiply this equation by -3:

-9x + 3y = -15            Now add this equation to the first equation:

-4x = -14

x = -14/-4 = 3.5.

Now substitute for x in equation 1:

5(3.5) - 3y = 1

-3y = 1 - 17.5

-3y = -16.5

y = 5.5.

Answer: The answer is C) J' (3,-1), K' (1,-4)

Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).

So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?

The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).

So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.

Answer:

The area of the model on the right is 80 sq cm

Step-by-step explanation:

Since the scale for the model on the left is 1 cm = 5 ft, and the scale for the model on the right is 1 cm = 2.5 ft, the area of the model on the right is 22, or 4, times larger than the area of the model on the left.

Multiply the area of the model on the left by 4 to find the area of the model on the right.

20 sq cm × 4 = 80 sq cm

Answer:

44

Step-by-step explanation:

2 x 2 = 4 which is the inner area without carpet.

Given:

A student used the proportion [tex]\dfrac{n}{100}=\dfrac{5}{26}[/tex] to find 5% of 26.

To find:

The student's mistake.

Solution:

Let 5% of 26 be n. Then,

[tex]n=\dfrac{5}{100}\times 26[/tex]

On dividing both sides by 26, we get

[tex]\dfrac{n}{26}=\dfrac{5}{100}[/tex]

So, the proportion used by the student was incorrect. The denominators of the proportion are interchanged.
