Answer 80 cm² 40 cm² 195.5 cm² 391 cm²​

Answer:

Step-by-step explanation:

To calculate Su-Lo's score on the test, we can multiply her percentage by the total marks for the test.

Su-Lo scored 45% out of 80, so her score can be calculated as follows:

Score = Percentage × Total marks

Score = 45% × 80

To find the score, we need to convert the percentage to a decimal by dividing it by 100:

Score = (45/100) × 80

Score = 0.45 × 80

Score = 36

Therefore, Su-Lo scored 36 marks on the test.

Answer: 18

Step-by-step explanation:

Multiply number of each item possible

3*2*3=18

The surface area of the cylinder is: 156π.

Here, we have,

given that,

the cylinder has:

radius = 6 in

height = 10 in

now, surface area of the cylinder is:

SA = 2πrh + πr²

here, we have,

SA = 2π *6 * 10 + π6²

     = 120π + 36π

     = 156π

Hence, The surface area of the cylinder is: 156π.

The factored expression of n² - 11n + 10 is (n - 10)(n - 1)

From the question, we have the following parameters that can be used in our computation:

n² - 11n + 10

To determine the pair of factors to factor the expression, we find two expressions

using the above as a guide, we have the following:

The expressions are -10n and -n

So, we have

n² - 11n + 10 = n² - 10n - n + 10

When factored, we have

n² - 11n + 10 = (n - 10)(n - 1)

Hence, the factored expression of n² - 11n + 10 is (n - 10)(n - 1)

Answer:

626.71 cm^2

Step-by-step explanation:

Area of figure = area of half circle + Area of half circle + area of a rectangle

here, diameter=15 cm

radius = 15/2=7.5 cm

length=30cm

breadth=15cm

Now

Area of figure = 1/2*π*radius^2+ 1/2*π*radius^2+length*breadth

=1/2* 1/2*π*7.5^2+1/2* 1/2*π*7.5^2+30*15

=626.71 cm^2

To find the height of the square pyramid, we can use the Pythagorean theorem. The slant height of the pyramid (s) is the hypotenuse of a right triangle formed by the height (h), half the length of the base (b/2), and the slant height.

Using the Pythagorean theorem:

s^2 = (b/2)^2 + h^2

We are given that the length of one of the base sides (b) is 23.8 and the slant height (s) is 89.3.

Plugging in the values:

89.3^2 = (23.8/2)^2 + h^2

Simplifying:

h^2 = 89.3^2 - (23.8/2)^2

h^2 = 7950.49 - 141.64

h^2 = 7808.85

Taking the square root of both sides:

h = √7808.85

h ≈ 88.37

Therefore, the height of the square pyramid is approximately 88.37 inches.[tex]\huge{\mathcal{\colorbox{black}{\textcolor{lime}{\textsf{I hope this helps !}}}}}[/tex]

Answer:

To solve the inequality −4p − (5p − 4) ≤ 7p + 10 + 3p, we can simplify and isolate the variable p. Let's work through the steps:

Step 1: Distribute the negative sign (-) inside the parentheses:

-4p - 5p + 4 ≤ 7p + 10 + 3p

Simplifying further:

-9p + 4 ≤ 10p + 10

Step 2: Group like terms by adding 9p to both sides of the inequality:

-9p + 9p + 4 ≤ 10p + 9p + 10

Simplifying further:

4 ≤ 19p + 10

Step 3: Subtract 10 from both sides of the inequality:

4 - 10 ≤ 19p + 10 - 10

Simplifying further:

-6 ≤ 19p

Step 4: Divide both sides of the inequality by 19:

-6/19 ≤ 19p/19

Simplifying further:

-6/19 ≤ p

So the solution to the inequality is p ≥ -6/19.

Answer:The max volume of Purple berry paint is 85

Step-by-step explanation:

P = 5 : 2

Simplify 5 : 2 which is 2.5 : 1

To determine how the surface area of a rectangular prism changes when all dimensions are quadrupled, we need to compare the original surface area to the new surface area.

The original surface area of the rectangular prism is given by:

SA_original = 2lw + 2lh + 2wh

where l, w, and h represent the length, width, and height of the prism, respectively.

In this case, the dimensions of the original box are:

Length (l) = 3 ft

Width (w) = 6 ft

Height (h) = 5 ft

Substituting these values into the formula, we have:

SA_original = 2(3)(6) + 2(3)(5) + 2(6)(5)

            = 36 + 30 + 60

            = 126 square feet

Now, if we quadruple all the dimensions of the box, the new dimensions would be:

Length (l_new) = 4(3) = 12 ft

Width (w_new) = 4(6) = 24 ft

Height (h_new) = 4(5) = 20 ft

The new surface area of the enlarged box is given by:

SA_new = 2(l_new)(w_new) + 2(l_new)(h_new) + 2(w_new)(h_new)

       = 2(12)(24) + 2(12)(20) + 2(24)(20)

       = 576 + 480 + 960

       = 2016 square feet

Comparing the original surface area (SA_original = 126 sq ft) to the new surface area (SA_new = 2016 sq ft), we can see that SA_new is 16 times greater than SA_original.

Therefore, the correct answer is:

1. The new surface area would be 16 times the original surface area.

A. 11.2

Step-by-step explanation:

But this has nothing to do with 5.6 × 2. Erase that! Lol.

You have a right triangle here. The only thing to do with the circle is that there are two radii (plural of radius) shown. So they have to be the same measure.

The unmarked "bottom" of the triangle, the short leg, is a radius, so it too, is 8.4.

The hypotenuse of the right triangle, the side on the right, the longest side is 5.6 + 8.4.

The hypotenuse is 14.

Let's do some Pythagorean Theorem.

Leg^2+ leg^2=hypotenuse^2

you know,

a^2 + b^2 = c^2

fill in what we know.

8.4^2 + b^2 = 14^2

simplify.

70.56 + b^2 = 196

subtract 70.56

b^2 = 125.44

squareroot both sides

b = 11.2

The area of the rectangle is 168 ft².

Step-by-step explanation:

Formula: A = lw

where l and w are the length and width of the rectangle respectively.

We're given with the length and the width as

a = 12 ft

b = 14 ft

Let's solve for the area using the formula above.

A = lw

A =  12ft(14ft)

A = 168 ft²

The degrees of freedom is 21, the critical values correspond to the points where the chi-square distribution curve separates the rejection and non-rejection areas and chi-square test statistic is 27.

The null and alternative hypotheses can be stated as follows:

Null Hypothesis (H0): The population variance is equal to 14.

Alternative Hypothesis (Ha): The population variance differs from 14.

To find the critical values of χ2 with α = 0.05, we need to determine the degrees of freedom first.

For a sample variance, the degrees of freedom (df) is given by (n - 1), where n is the sample size.

In this case, n = 22, so the degrees of freedom is 21.

Using a chi-square table or statistical software, we can find the critical values for a chi-square distribution with 21 degrees of freedom and α = 0.05.

The critical values correspond to the points where the chi-square distribution curve separates the rejection and non-rejection areas.

To determine the test statistic χ2 value, we need to calculate the chi-square test statistic using the given information.

The chi-square test statistic is calculated as:

χ2 = (n - 1) ×(sample variance) / (population variance)

Plugging in the values, we have:

χ2 = (22 - 1) × 18 / 14

Answer:

  38.9 in²

Step-by-step explanation:

You want the area of the composite figure that is an 8-inch square with a semicircle removed.

The missing semicircle has a diameter of 8 in, so a radius of 4 in. The area of that half-circle is ...

  A = 1/2πr² = (π/2)(4 in)² = 8π in² ≈ 25.1 in²

The area of the square without the semicircle removed is ...

  A = s² = (8 in)² = 64 in²

After removing the semicircle from the square, the remaining area is ...

  A = square area - semicircle area

  A = 64 in² -25.1 in² = 38.9 in²

The area of the figure is about 38.9 square inches.

BC = 5.1

m∠B = 23°

m∠V = 116°

Step-by-step explanation:

Givens:

AC = 3

AB = 7

m∠A = 41°

Unknowns:

BC = ?

m∠B = ?

m∠C = ?

Find side BC using the law of cosines:  c² = a² + b² - 2ab cos(C)

a² = 3² + 7² - 2(3)(7)(cos41)

a = √9 + 49 - 42(cos41)

a = 5.128 ≈ 5.13

side BC = 5.13

Use the law of sines to find m∠B:  sin(A) / a = sin(B) / b = sin(C) / c

m∠B = sin⁻¹[sin41/5.13 x 3] = sin⁻¹(0.3837) = 22.56 ≈ 22.6°

Sum of interior angles of a triangle is 180, so now you can find m∠C:

m∠C = 180 - 22.6 - 41 = 116.44 ≈ 116.4°

Rounding side BC to nearest tenth: BC = 5.1

Rounding angles to nearest whole degree:

m∠B = 23°

m∠V = 116°
