Answer: 6 purple rectangles

Step-by-step explanation: We know that each scarf will have 5 rectangles and 2/5 of the rectangles will be purple: 2/5 * 5 = 2. It means that each scarf will have 2 purple rectangles. And for 3 scarves : 3 * 2 = 6. Answer: She needs 6 purple rectangles.

Step-by-step explanation:

sin²x = 2 - 2cosx

1 - cos²x = 2 - 2cosx (because sin²x + cos²x = 1)

cos²x - 2cosx + 1 = 0

(cosx - 1)² = 0

cosx - 1 = 0

cosx = 1

Hence x = 0.

Answer:

The answer remains the same (45.3191)

Step-by-step explanation:

0.029 is 100 times smaller than 2.29 but 1979 is 100 times bigger than 19.79. The 100’s cancel each other out so the answer remains the same.

Answer:

108 degrees

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle  = 108 degrees

Hence the measure of the exterior angle is 108 degrees

Answer:

m∠1 = 124°

Step-by-step explanation:

If this is the case then m∠1 and m∠2 are congruent to each other with the same angle in which m∠2 is also 124°, if m∠3 is said to be 56°.  Also, a straight angle has to equal to 180° in which the first angle is classified as obtuse.

Answer:

1042

Step-by-step explanation:

-38,-8,22,52

The common difference is 52 - 22 = 30

a_1 = -38

a_2 = -38 + 30

a_3 = -38 + 2 * 30

a_4 = -38 + 3 * 30     (notice that the common difference is multiplied by 1 less than the term number)

a_n = -38 + (n - 1)30      (since the term number is n, we multiply the common difference by n - 1)

a_n = -38 + 30(n - 1)

a_37 = -38 + 30(37 - 1)

a_37 = 1042

Answer:

Does not represent a polynomial

Step-by-step explanation:

Answer:

Does not represent a polynomial.

Step-by-step explanation:

In particular, for an expression to be a polynomial term, it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.

Answer:

m = 1/3 and b = - 4

Step-by-step explanation:

The equation already gives the answer as the equation is in slope-intercept form.

[tex]y = mx + b[/tex]

Where m = slope and b = y-intercept.

From the equation —

[tex]y = \frac{1}{3} x - 4 \\ m = \frac{1}{ 3} \\ b = - 4[/tex]

Therefore, our slope is 1/3 and y-intercept is - 4.

Answer:

The 93% confidence interval of the true proportion of people who watched educational TV

(0.73716 , 0.80684)

Step-by-step explanation:

Step(i):-

Given sample size 'n' = 145

A random sample of 145 people, 112 said that they watched educational TV.

Sample proportion

                         [tex]p^{-} = \frac{112}{145} = 0.772[/tex]

Step(ii):-

The 93% confidence interval of the true proportion of people who watched educational TV

[tex](p- Z_{0.07}\sqrt{\frac{pq}{n} } , p + Z_{0.07} \sqrt{\frac{pq}{n} } )[/tex]

[tex](0.772- 1.427\sqrt{\frac{0.772X0.228}{145} } , 0.772 + 1.427 \sqrt{\frac{0.772X0.228}{145} } )[/tex]

( 0.772 - 0.03484 , 0.772 + 0.03484)

(0.73716 , 0.80684)

Final answer:-

The 93% confidence interval of the true proportion of people who watched educational TV

(0.73716 , 0.80684)

Which do you enjoy the most?

Answer:

There are 4 items being purchased

Answer:

£27

Step-by-step explanation:

From the above question, we know that:

The price of a shirt is usually = £45. During a sale the prices in the shop are reduced by 2/5 .

Hence, the amount that the cost of tht shirt is reduced by is :

£45 × 2/5

= £18

The cost of this shirt in the sale is calculated as:

£45 - £18

= £27

Answer:

25

Step-by-step explanation:

= 3*3*3 + 3 - 5 = 27+3-5

27+3-5= 30-5

30-5=25

have a wonder full day

Answer:

It's B. 25.

Step-by-step explanation:

Substitute x, the variable with 3. First solve [tex]3^{3}[/tex] which is 27 and then 3-5 which is -2. Then, add the two and you will get 25.

When you divide one number by another, the result is called the quotient. This is true for rational expressions too! When you divide one rational expression by another, the result is called the quotient.

Answer:

75.187 $

Step-by-step explanation:

I did it this way:

65.38$ : 100% = X : 115%

100X = 65.38 x 115

100X = 7518.7

X = 7518.7 ÷ 100

X = 75.187

Using translation concepts, it is found that:

The graph of g(x) is a translation of f(x) 2 units down.

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

Translating a function f(x) a units down is the same as finding f(x) - a.

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

In this question:

Thus, g(x) is f(x) translated 2 units down, and the correct option is:

The graph of g(x) is a translation of f(x) 2 units down.

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

At the end, the graph is given, with f(x) in red and g(x) in blue.

Answer:

x = 10

y = 5

Step-by-step explanation:

Since, two lines p and q are the parallel lines and FA is a transversal line intersecting these parallel lines.

ΔAOB and ΔDOC are the similar triangles.

Therefore, by the property of similar triangles, corresponding sides of the similar triangles will be proportional.

[tex]\frac{AO}{OD}= \frac{OB}{OC}[/tex]

[tex]\frac{x}{15}= \frac{8}{12}[/tex]

x = [tex]\frac{15\times 8}{12}[/tex]

x = 10

Similarly, triangles AOB and OEF will be similar.

And by the property of similar triangles,

[tex]\frac{AO}{OF}= \frac{OB}{OE}[/tex]

[tex]\frac{x}{15+y}= \frac{8}{12+4}[/tex]

[tex]\frac{10}{15+y}= \frac{8}{16}[/tex]

8(15 + y) = 160

120 + 8y = 160

8y = 160 - 120

8y = 40

y = 5

Answer:

C. 10 + squareroot10 units

Step-by-step explanation:

Answer:

[tex]a=-\frac{c-b}{2}[/tex]

Step-by-step explanation:

Solving for the variable [tex]a[/tex], given that :

[tex]b-2a=c[/tex]

We can first start start by subtracting [tex]b[/tex] from both sides of the equation:

[tex]-2a=c-b[/tex]

Now, we can divide both sides of the equation by the coefficient of [tex]a[/tex], which would be [tex]-2[/tex]:

[tex]a=\frac{c}{-2}-\frac{b}{-2}[/tex]

Applying the fraction rule [tex]\frac{a}{c}\pm\frac{b}{c} =\frac{a\pm b}{c}[/tex]:

[tex]a=\frac{c-b}{-2}[/tex]

Then, apply the fraction rule [tex]\frac{a}{-b} =-\frac{a}{b}[/tex]

[tex]a=-\frac{c-b}{2}[/tex]
