Answer:

9 cm

Step-by-step explanation:

Formula :

Area (parallelogram) = Base × Height

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

Given :

⇒ Area = 153 cm²

⇒ Height = 17 cm

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

Solving :

⇒ 153 cm² = 17 cm × Base

⇒ Base = 153/17

⇒ Base = 9 cm

Answer:

Base = 9 cm

Step-by-step explanation:

Given dimensions:

To Find:

Solution:

This question is a bit tricky.Usually,the height and the base are given. We'll use the formula of area of parallelogram , then substitute/plug the values of height and area of parallelogram, with the exception of base as it's not given.

So recall the formulae of area of parallelogram:

[tex] \rm \: Area_{(Parallelogram)} = b \cdot{h}[/tex]

Plug/substitute the values of area of parallelogram & height:

[tex]\rm \: 153 \: cm ^2 =b \cdot17 \: cm[/tex]

We created an equation.Solve it now.

[tex] \implies \rm \cfrac{153 \: cm^2}{17 cm} = base[/tex]

[tex] \implies \rm9 \; cm = \: base[/tex]

[tex] \implies \rm \: Base = 9\; cm[/tex]

Yes! We're done!

Hence,the base is 9 cm of the parallelogram.

The surface area of the composite figure is 144 square cm after calculating separately.

When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is the name given to this novel 3D object.

We have a composite figure made up of a triangular prism and a cuboid

First we calculate the surface area of the triangular prism:

= 2(area of one triangle) + area of three rectangles

= 2[(1/2)6×4] + 3×5 + 3×5

= 24 + 15 + 15

= 54 square cm

Surface area of rectangle(with three faces) = 2(4×3 + 4×6) + 3×6

= 2(12 + 24) + 18

= 72 + 18 = 90 square cm

Total surface area of figure = 54+ 90 = 144 square cm

Thus, the surface area of the composite figure is 144 square cm after calculating separately.

The two numbers where the digit 6 has a value of 0.6 are 14.63 and 85.62.

To determine in which two numbers the digit 6 has a value of 0.6, we need to examine the place value of 6 in each number.

Let's go through each number:

1. 16.7: The digit 6 is in the tens place, so its value is 6 * 10 = 60 (not 0.6).

2. 61.28: The digit 6 is in the ones place, so its value is 6 (not 0.6).

3. 14.63: The digit 6 is in the tenths place, so its value is 6 * 0.1 = 0.6.

4. 28.16: The digit 6 is in the hundredths place, so its value is 6 * 0.01 = 0.06.

5. 96.77: The digit 6 is in the tens place, so its value is 6 * 10 = 60 (not 0.6).

6. 85.62: The digit 6 is in the tenths place, so its value is 6 * 0.1 = 0.6.

Answer:

1. ΔHIJ ≅ ΔLMN

2. ΔXYZ ≅ ΔJKL

Step-by-step explanation:

I believe it's asking to list the corresponding sides and pairs of angles in the congruent triangles.

Look at the order of the letters HIJ and LMN. There are 3 letters, which represent 3 sides and 3 angles. The first, second, and third letters of the first triangle correspond to the first, second, and third letters of the second triangle.

1. ΔHIJ ≅ ΔLMN

2. ΔXYZ ≅ ΔJKL

Using the cosine rule, the measure of the triangles is a = 51, b = 21, c = 68, A = 30.37°, B = 12.02° and C = 137.61°

An equation is an expression that shows the relationship between two or more numbers and variables.

Cosine rule is given as:

a² = b² + c² - 2bc * cosA

Given that a = 51, b = 21, c = 68, hence:

51² = 21² + 68² - 2(21)(68) * cosA

A = 30.37°

21² = 51² + 68² - 2(51)(68) * cosB

B = 12.02°

68² = 21² + 51² - 2(21)(51) * cosC

C = 137.61°

Using the cosine rule, the measure of the triangles is a = 51, b = 21, c = 68, A = 30.37°, B = 12.02° and C = 137.61°

Answer:

Step-by-step explanation:

Answer:

x = 25 - y = 2

Step-by-step explanation:

Let x represent the number of item A that you sold.

Let y represent the number of item B that you sold.

The total number of item A and item B sold is 25. This means that

x + y = 25

The cost of item A is $3, the cost of item B is $4 and if the total amount of money made is $88, this implies

3(x) + 4(y) = 88 (Substitute x = 25 - y)

→ 3(13 - y) + 4y = 88

→ 39 - 3y + 4y = 88

→ 39 + y = 16

→ y = 23

If y = 23, then x = 25 - y = 2

The zero of the linear function is -2

The equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

The attached table of values represents the missing piece in the question.

Start by calculating the rate of change using:

m = (y2 - y1)/(x2 - x1)

This gives

m = (14.77 - 10.55)/(7- 5)

Evaluate

m = 2.11

The equation is then calculated using:

y = m(x - x1) + y1

This gives

y = 2.11(x - 5) + 10.55

Evaluate

y = 2.11x - 10.55 + 10.55

y = 2.11x

Hence, the equation that represents the relationship between the number of liters, x, and the number of liquid pints, y is y = 2.11x

(i) Both are boys = 0.3575757576, (ii) Both are girls = 0.1575757576 and (iii) one boy and one girl = 0.48484848 are the probabilities.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

Given:

A class consists of 60 boys and 40 girls.

To find the probability if two students are chosen at random:

The probability is ¹⁰⁰C₂.

(i) Both are boys,

The probability is ⁶⁰C₂ ÷ ¹⁰⁰C₂.

⁶⁰C₂ ÷ ¹⁰⁰C₂ = 60! / {2! x (60-2)!} ÷ 100! / {2! x (100-2)!}

⁶⁰C₂ ÷ ¹⁰⁰C₂ = 30 x 59 / 50 x 99

⁶⁰C₂ ÷ ¹⁰⁰C₂ =0.3575757576

(ii) Both are girls,

The probability is ⁴⁰C₂ ÷ ¹⁰⁰C₂.

⁴⁰C₂ ÷ ¹⁰⁰C₂ = 40! / {2! x (40-2)!} ÷ 100! / {2! x (100-2)!}

⁴⁰C₂ ÷ ¹⁰⁰C₂ = 20 x 39 / 50 x 99

⁴⁰C₂ ÷ ¹⁰⁰C₂ =0.1575757576

(iii) one boy and one girl,

The probability is ⁴⁰C₁ ×  ⁶⁰C₁  ÷ ¹⁰⁰C₂.

⁴⁰C₁ ×  ⁶⁰C₁  ÷ ¹⁰⁰C₂ =

40! / {1! x (40-1)!}x 60! / {1! x (60-1)!} ÷ 100! / {2! x (100-2)!}

⁴⁰C₁ ×  ⁶⁰C₁  ÷ ¹⁰⁰C₂ = 40x60 / 50 x 99

⁴⁰C₁ ×  ⁶⁰C₁  ÷ ¹⁰⁰C₂=0.48484848

Therefore, the probabilities are (i) Both are boys = 0.3575757576, (ii) Both are girls = 0.1575757576 and (iii) one boy and one girl = 0.48484848

When x = 5 , y = 8(5)^2 + 10 = 210 , and on graph its 200

Calculating y for other values:

When x = 7, y = 8(7)^2 + 10 = 402, and on graph y =  400.

When x = 11, y = 978 , and on graph  =  1000.

When x = 17, y = 2322, and on graph y = about 2350.

The area of a 2D form is the amount of space within its perimeter. The total surface area of the square pyramid is 40 meters².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

Henri built a lantern in the shape of a square pyramid. He wants to cover the entire pyramid with fabric. Therefore, the amount of fabric that Henri will need is equal to the total surface area of the square pyramid.

Total surface area = Area of the base + 4(Area of the triangle)

                               = (4m × 4m) + 4(0.5×4m×3m)

                               = 16 meters² + 24 meters²
