Answer:

-15

Step-by-step explanation:

(5) x (-3) = -15

Answer:

x = 2.3

Step-by-step explanation:

Since we know all three sides, what we do here is multiply side a & b's lengths together and divide by the hypotenuse. (a + b)/c

(2.5 * 6)/6.5

Step 1: Multiply 2.5 by 6 to get 15.

15/6.5

Step 2: Convert 6.5 into a whole number by multiplying it by 10. Make sure to do that to the 15 as well.

150/65

Step 3: 150/65 simplifies to 30/13 (GCF: 5).

30/13

Step 4: 30/13 becomes 2 4/13.

2 4/13

Step 5: 2 4/13 rounds to 2.3

2.3 is the value of x.

Answer:

3rd option: The number of protons and neutrons

Step-by-step explanation:

Protons are positively charged

Neutrons are negatively charged

You can easily remember this by the P and N

For an object to be "neutral", the protons and neutrons have to be equal. If they are not equal it will be positively charged of negatively charged.

Answer:

14 m is more

Step-by-step explanation:

14 meters = 1400 cm

14 x 100=1400

Answer:

14 m is more

Step-by-step explanation:

1 m = 100 cm

14 m

= 14 x 100

= 1400 cm

1400 cm > 140 cm

14 m > 140 cm

Answer:

Option D = 16π/3 ft

Step-by-step explanation:

Arc length formula is written Mathematically as:

Arc length = 2πr × θ /360

r = 4 ft

θ = Central angle in degrees = 240°

2 × π × 4 × 240/360

8π × 240/360

8π × 20/30

16π/3 ft

So, the arc length is 16π/3 ft

Answer: 152ft squared

Step-by-step explanation:

When solving the area of a triangle you multiply by 1/2 so your equation would be 1/2*16*19 = 152ft squared. (Do not forget your units in other problems!!!)

Answer:

A

Answer: [tex]6x-5[/tex]

Step-by-step explanation:

Given

The side lengths of a triangle are  [tex]3x-5, 2x-1,\text{and}\ x+1[/tex]

Perimeter(P) is the sum of the side length of the triangle i.e.

[tex]\Rightarrow P=3x-5+2x-1+x+1\\\Rightarrow P=6x-5[/tex]

Therefore, the perimeter of the triangle is [tex]6x-5[/tex]

Answer:

p = 7

Step-by-step explanation:

Answer:

B) -1

Step-by-step explanation:

Move point A to one, it has moved 1/2

Move to 0 it has moved 1 1/2 from point A

Move to -1 it has moved 2 1/2 from point A

Answer:

x<1 I believe.

Step-by-step explanation:

Subtract -5 from 5 and do the same with the other side making the other side 1. So you get left with the answer.

3z + 2(z - 3) = 7z + 12

3z + 2(z - 3) = 7z + 12

3z + 2z - 6 = 7z + 12

3z + 2z - 7z = 12 + 6

5z - 7z = 18

-2z = 18

z = 18/2

z = 9

3z + 2(z - 3) = 7z + 12

3z + 2(z - 3) = 7z + 12

3z + 2z - 6 = 7z + 12

3z + 2z - 7z = 12 + 6

5z - 7z = 18

-2z = 18

z = 18/2

Answer:

75

Step-by-step explanation:

175= 25+2a

The number of laps that Swimmer A swam was 50 laps.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Let we suppose that:

Then, according to the given data, we have:

x + y = 175 laps

y = 25 + 2x (25 more than twice of laps of A is the number of laps of B).

Thus, we get a system of two equations as:

[tex]x + y = 175\\y = 25 + 2x\\[/tex]

From second equation, putting value of y in first equation, we get:

[tex]x + (25 + 2x) = 175\\3x + 25 = 175\\3x = 150\\\\x = \dfrac{150}{3} = 50 \: \rm laps[/tex]

As x is the number of laps Swimmer A swam, thus, the number of laps that Swimmer A swam was 50 laps.

Answer:0.82

Step-by-step explanation:

The first step is to determine the areas of the inner and the bigger circles.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

diameter = 148.4 cm

Radius = 3 inches

Area = 3.14 × 3² = 28.26 inches²

Considering the bigger circle,

Radius = 7 inches

Area = 3.14 × 7² = 153.86 inches²

The area between the bigger and inner circles is

153.86 - 28.26 = 125.6 inches²

Probability = number of favourable outcome/number of total outcome.

the probability you land inside the bigger circle but outside smaller circle is

125.6/153.86 = 0.82
