Answer:

Becky and her brother made 90+63=153 masks in total

Step-by-step explanation:

Percentages

Let's call x=number of masks Becky's brother made.

We know Becky made 30% less than the number of masks her brother made.

30% of x is calculated by:

30*x/100 = 0.3x

Now subtracting from x:

x - 0.3x = 0.7x

Becky made 63 carnival masks, this means that:

0.7x = 63

Dividing by 0.7:

x = 63/0.7 = 90

Becky's brother made 90 masks.

Becky and her brother made 90+63=153 masks in total

Answer:

150 ft^2

Step-by-step explanation:

The formula is (30*10)/2 which is equal to 150.

Answer:

K = 15

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine x = 1/4

Cos² x = K / 16

K =?

Next, we shall determine the 3rd leg (i.e the adjacent) of the right angle triangle. This can be obtained as follow:

Sine x = 1/4

Sine x = Opposite / Hypothenus

Opposite = 1

Hypothenus = 4

Adjacent =?

Hypo² = Opp² + Adj²

4² = 1² + Adj²

16 = 1 + Adj²

Collect like terms

16 – 1 = Adj²

15 = Adj²

Take the square root of both side.

Adj = √15

Next, we shall determine Cos² x.

Adjacent = √15

Hypothenus = 4

Cos² x =?

Cos x = Adjacent / Hypothenus

Cos x = √15 /4

Square both side

Cos² x = (√15 /4)²

Cos² x = 15 / 16

Finally, we shall determine the value of K. This can be obtained as follow:

Cos² x = K / 16

Cos² x = 15 / 16

K / 16 = 15 / 16

K = 15

Answer:

d + 10d + 25q = 229.

Step-by-step explanation:

Answer:

15 % off

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 148 × 15/100

Discount = 148 x 0.15

You save = $22.20

Final Price = Original Price - Discount

Final Price = 148 - 22.2

Final Price = $125.80

‐3×2y2 is the most common correct answer

Answer:

The value of q that makes the expression a perfect square is q = 4.

Step-by-step explanation:

Perfect square:

A perfect square expression has the following format:

[tex](a - b)^2 = a^2 - 2ab + b^2[/tex]

In this question:

[tex]9x^2 - 12x + q[/tex] is a perfect square, we have to find the value of q.

First we have to find the value of a, looking at the equivalent formula above. So

[tex]a^2 = 9x^2[/tex]

[tex]a = \sqrt{9x^2}[/tex]

[tex]a = 3x[/tex]

Since the second term, which is -2ab, is -12x, we have that:

[tex]-2ab = -12x[/tex]

[tex]-2(3x)b = -12x[/tex]

[tex]-6xb = -12x[/tex]

[tex]6b = 12[/tex]

[tex]b = \frac{12}{6}[/tex]

[tex]b = 2[/tex]

q is b squared. So

[tex]q = b^2 = 2^2 = 4[/tex]

The value of q that makes the expression a perfect square is q = 4.

Answer:

d. None of these

Step-by-step explanation:

Hope it helps you in your learning process.

[tex] m\angle 1 + m\angle 2 + 90\degree = 360\degree [/tex]

[tex] m\angle 1 + m\angle 2 = 360\degree- 90\degree [/tex]

[tex] m\angle 1 + m\angle 2 = 270\degree [/tex]

Answer:

D. None of the above.

Step-by-step explanation:

Complementary are 90 degrees and supplementary are 180 degrees.

A full circle is 360 degrees, and since there is a right angle, that means that angle 1 and 2 make up 270 degrees total.

This means it is neither.

Answer: 414

Step-by-step explanation: 414 is a palindrome that is divisible by 18 because it’s an even number and that it’s one less than 415 which is a multiple of 5.

Kayla's number is 414 and this can be determined by using the given data and also by using the arithmetic operations.

Given :

The following steps can be used in order to determine Kayla’s number:

Step 1 - Remember palindrome means 'reads the same left-to-right as it does right-to-left'.

Step 2 - The digit should be between 0 to 9 and according to the given data, the number is one than a multiple of 5 that is, the first and last digit must be 4 or 9.

Step 3 - So, the number which is divisible by 18 is 414.

Question- What method would you happen to be using to solve this problem?

Answer:

(5, 5.25) , (10, 6.50) , (20, 9)

Step-by-step explanation:

As given ,

y = 0.25x + 4

Now,

if x = 5

⇒ y = 0.25(5) + 4

      = 1.25 + 4

     = 5.25

⇒ y = 5.25

∴ the ordered pair be (x, y) = (5, 5.25)

if x = 10

⇒ y = 0.25(10) + 4

      = 2.5 + 4

     = 6.50

⇒ y = 6.50

∴ the ordered pair be (x, y) = (10, 6.50)

if x = 20

⇒ y = 0.25(20) + 4

      = 5 + 4

     = 9

⇒ y = 9

∴ the ordered pair be (x, y) = (20, 9)

First let's review how to expand this!

(ax+b)^2=a^2*x^2+2abx+a^2

In this case

(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2

=4x^2+2x+1/4

Done!

Given:

The polynomial function is

[tex]q(x)=6x^3+19x^2-15x-28[/tex]

Yuri thinks that [tex]\dfrac{3}{4}[/tex] is a root of the given function.

To find:

Why [tex]\dfrac{3}{4}[/tex] cannot be a root?

Solution:

We have,

[tex]q(x)=6x^3+19x^2-15x-28[/tex]

If [tex]\dfrac{3}{4}[/tex] is a root, then the value of the function at [tex]\dfrac{3}{4}[/tex] is 0.

Putting [tex]x=\dfrac{3}{4}[/tex] in the given function, we get

[tex]q(\dfrac{3}{4})=6(\dfrac{3}{4})^3+19(\dfrac{3}{4})^2-15(\dfrac{3}{4})-28[/tex]

[tex]q(\dfrac{3}{4})=6(\dfrac{27}{64})+19(\dfrac{9}{16})-\dfrac{45}{4}-28[/tex]

[tex]q(\dfrac{3}{4})=3(\dfrac{27}{32})+\dfrac{171}{16}-\dfrac{45}{4}-28[/tex]

[tex]q(\dfrac{3}{4})=\dfrac{81}{32}+\dfrac{171}{16}-\dfrac{45}{4}-28[/tex]

Taking LCM, we get

[tex]q(\dfrac{3}{4})=\dfrac{81+342-360-896}{32}[/tex]

[tex]q(\dfrac{3}{4})=\dfrac{-833}{32}\neq 0[/tex]

Since the value of the function at [tex]\dfrac{3}{4}[/tex] is not equal to 0, therefore, [tex]\dfrac{3}{4}[/tex] is not a root of the given function.

Answer:

[tex]t \ge h[/tex] and [tex]t + 0.5h \le 12.0[/tex]

Step-by-step explanation:

Given

[tex]t= thickness[/tex]

[tex]h =height[/tex]

From the first statement, we have that:

[tex]t\ mm \ge 0.1 * h\ cm[/tex]

Convert mm to cm

[tex]t\ * 0.1*cm \ge 0.1 * h\ cm[/tex]

[tex]t\ *0.1 \ge 0.1 * h[/tex]

Divide both sides by 0.1

[tex]t \ge h[/tex]

From the second statement, we have that:

[tex]Cost \le 12.2[/tex]

Substitute 0.2 + t + 0.5h for Cost

[tex]0.2 + t + 0.5h \le 12.2[/tex]

Collect Like Terms:

[tex]t + 0.5h \le 12.2-0.2[/tex]

[tex]t + 0.5h \le 12.0[/tex]

So, the inequalities are:

[tex]t \ge h[/tex] and [tex]t + 0.5h \le 12.0[/tex]

Answer: it's a, the answer

Step-by-step explanation:

=====================================================

Work Shown:

Applying the tangent-secant theorem will allow us to solve for x

x*(x+5) = (x+2)^2

x^2+5x = (x+2)*(x+2)

x^2+5x = x^2+4x+4

5x = 4x + 4 ..... subtracting x^2 from both sides; terms cancel

5x-4x = 4

x = 4

------------------

Check:

Plug in x = 4

x*(x+5) = (x+2)^2

4*(4+5) = (4+2)^2

4*(9) = (6)^2

36 = 36

The answer is confirmed.
