The Mohs scale is used to measure:

streak
cleavage
hardness
luster

Answer:

It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not. So then the answer is A

Answer:

√340=18.43

Step-by-step explanation:

using, pythogoras theorem.

we should find h , where p=14 and b=12

thank you

Answer:

the answer would be ≈18.4

Step-by-step explanation:

I used the pythagorean theorem to find the value for the hypotenuse and then rounded the answer by the nearest tenth to get approximately 18.4 , hope this helps!

Answer: 23

Step-by-step explanation: because you subtract

Answer:

Change the minus sign to a plus. 2. ... 24. = 8. 11. 24. Find each quotient. 1. 1. 3. 1. 6. 2. 5. 8. 1. 16. 2. 1. 3 x. 6. 1 = 6 ... Write a variable expression to represent the word phrase.

The correct expression for the given condition is,

⇒ (16 ÷ 8) + 24

An expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division is called mathematical expression.

We have to given that;

The algebraic expression is,

''add 24 to the quotient of 16 and 8.''

Now, We can write the expression as;

Quotient of 16 and 8 is,

⇒ 16 ÷ 8

And, Add 24 to the quotient of 16 and 8.

⇒ (16 ÷ 8) + 24

Thus, The correct expression for the given condition is,

⇒ (16 ÷ 8) + 24

Answer:

140

Step-by-step explanation:

30% of a number(x) is 105. To find the number(x) we must set up the equation below and solve for x:

0.3=105/x (multiply x)

0.3x=105 (divide by 0.3)

x=350

Solve for 40% of the number by multiplying 0.4 by the number:

350x.4=140

Answer:

146.96 [tex]m^2[/tex]

Step-by-step explanation:

1. Approach

Divide this figure into two smaller shapes. Calculate the area of these smaller shapes, and then add the results. One can divide this shape into a semi-circle, and a triangle.

2. Area of the triangle

The formula to find the area of a triangle is;

[tex]\frac{base*height}{2}[/tex]

It is given that the base of the triangle is (14m) and the height is (10m). Substitute in these values, and solve for the area,

[tex]\frac{14*10}{2}\\= \frac{140}{2}\\= 70[/tex]

2. Area of the semi-circle

The area of the semi-circle can be found by finding the area of the larger circle, and then divide it by 2, since a semi-circle is half of a circle. The formula for the area of a semi-circle is;

[tex]\frac{(pi)(r^2)}{2}[/tex]

Where (pi) is the constant (3.1415...), (r) represents the radius of the circle, which by definition is half of the diameter. Substitute in the values and solve;

[tex]\frac{(pi)(7)^2}{2}\\= \frac{3.14*49}{2}\\=76.96[/tex]

3. Find the total area;

Now add up the two values for the area of the figures;

Triangle + Semi-circle

= 70 + 76.96

= 146.96

Answer:

Consecutive angles are supplementary is not character of parallelograms

Answer: 62.4 computers or 62

Step-by-step explanation:

Use this equation

48(n)

n will be 0.30 since the sales must increase by 30%

48(0.30)

14.4

Now add 48 and 14

48+14.4

62.4 or round it down to 62

Answer:

p=0, p=.25

Step-by-step explanation:

p*(4p-1)=0

p=0. when the product of factors equals zero at least one factor is zero

4p-1=0

p=1/4 or .25

Answer:

A. 3/12

Step-by-step explanation:

1/4 x 3 for the three different bags and each bag having 1 crayon that's the color green it's 1/4 however due to there being 4 crayons in each bag

the only other answer could be 1/4 when simplified

Answer:

Step-by-step explanation:

1 bag of crayons = 4 crayons = 100% (10/10)

1/4 bag of crayons = 1 crayon = 25% = 1 green crayon per bag

3 bags of crayons = 12 crayons (3 x 4)

if 1 bag has 1 green crayon and there are 3 bags then there are 3 green crayons

Step-by-step explanation: When you multiply 100 x 100 you get 10,000.

Answer:

54.

Step-by-step explanation:

( 8 + √ 10 ) ( 8 − √10)

= 8*8  - 8√10 + 8√10  +√10 *  -√10

= 64 -  8√10 + 8√10 - 10

The 2 middle turns cancel out so we have:

64 - 10

= 54.

Step-by-step explanation:

Answer:

Area = 139.27 m²

Step-by-step explanation:

Area of the composite figure = area of rectangle + area of semicircle

= (L*W) + ½(πr²)

L = 10 m

W = 10 m

r = ½ of 10 = 5 m

Plug in the values

Area = (10*10) + ½(π*5²)

Area = 100 + 39.27

Area = 139.27 m²
