the area of the parallelogram.

[tex]formula = bh[/tex]

[tex]a = 6 \times 10[/tex]

[tex]a = 60 {cm}^{2} [/tex]

therefore, the area of the parallelogram is 60 square centimeters.

answer= option c.

Answer:

-3 or 10

Step-by-step explanation:

[tex]x(x - 7) = 30[/tex]

[tex] {x}^{2} - 7x = 30[/tex]

[tex] {x}^{2} - 7x - 30 = 0[/tex]

[tex](x - 10)(x + 3) = 0[/tex]

x = -3 or 10

Answer:

See below

Step-by-step explanation:

a)   47/100

b)  .4777777.....   =x

      then 10x = 4.77777....

      100x = 47.777777 ....   now subtract 10x to get

          90x = 43

             x = 43/90

c) .4747474747......   = x

        100x = 47.474747    now subtract x to get

          99x = 47

             x = 47/99

Answer:

20 m²

Step-by-step explanation:

Formula (Area of triangle):

[tex]\text{A (Triangle)} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]

From the triangle, we can see that the base of the triangle is "7 + 3" m and the height of the triangle is "4" m.

[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (7 + 3) \times (4)[/tex]

Simplify the right-hand-side as needed to evaluate the area.

[tex]\implies \text{A (Triangle)} = \dfrac{1}{2} \times (10) \times (4)[/tex]

[tex]\implies \text{A (Triangle)} = \dfrac{40}{2} = 20 \ \text{m}^{2}[/tex]

Therefore, the area of the provided triangle is 20 m².

The convincing evidence is Yes, because a mean mileage of 52,000 or more occurred only 7 out of 200 times, the mean mileage is statistically significant.

A dot plot is known to have the same characteristics as  a bar graph as both are made up of different height of “bar” that consist of dots which is said to be equal to the number of items in any of the stages or categories.

Conclusively, when a person  uses a dot plot and the sample mean mileage, one will be able to find a convincing evidence that the new type of tread improves the mileage because out of  mean mileage of 52,000 or more, only 7 out of 200 times,  took place and this shows that the mean mileage is statistically significant and that the new type of tire tread boast the mileage of the tire.

Therefore, option A is correct.

Answer:

111.548

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

Subtract 201 from 89.

[tex]201 - 89 = 112[/tex]

we can estimate the answer will be close to 112

Next, work with the decimals. Note that the more you subtract, the bigger the decimal places get.

[tex]0.768 - 0.316 = 0.452[/tex]

Round 0.452 up from the hundredths place to nearest tenths place.

[tex]0.452 = 0.5[/tex]

Since the decimal place is bigger, estimate 0.55 instead.

Subtract 0.22

[tex]0.55 - 0.2 = 0.548[/tex]

Add this number to 112

[tex]112 + 0.548 = 112.548[/tex]

Subtract 1 because of the estimate.

[tex]112 - 1 = 111[/tex]

Therefore, we have 111.548 based off of subtracting and estimating in a specific method.

The percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

Given that:

        Genre       number sold

Let we have:
Number of horror books sold = P% greater than number of cookbooks sold

55 = P% greater than 54

55 = 54 + P% of 54

1 = P% of 54

[tex]1 = \dfrac{P}{100} \times 54\\\\P = \dfrac{100}{54} \approx 1.85[/tex]

Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

By applying fundamental and derivate trigonometric expressions it is to be concluded that the secant of the line segment whose terminal side is (3, - 2) is approximately 1.202.

Trigonometric expressions are trascendent expressions derived from relationships between sides of the triangle contained in a goniometrical diagram.

There are at least six trigonometric expressions: sine, cosine, tangent, cotangent, secant, cosecant. The first two expressions are fundamental, whereas the rest are derived from them.

We can derive an expression for the secant of the angle by applying trigonometric expressions:

[tex]\sec \theta = \frac{1}{\cos \theta} = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex]     (1)

If we know that x = 3 and y = - 2, then the secant of the angle is:

[tex]\sec \theta = \frac{\sqrt{3^{2}+(-2)^{2}}}{3}[/tex]

sec θ ≈ 1.202
