Is -14 an integer or not

2 answers:

3 0

An integer is a whole number (not a fraction) that can be positive, negative, or zero. Therefore, the numbers 10, 0, -25, and 5,148 are all integers. When two integers are added, subtracted, or multiplied, the result is also an integer.

Can someone PLEASEEE help me with this for questions 3-5

zhuklara [117]

Answer:

The answer to your question is below

Step-by-step explanation:

3.-

P(A) = 0.3

P(A and B) = 0.24

P(B) = ?

P(B) = P(A) - P(A and B)

P(B) = 0.3 - 0.24

P(B) = 0.06

4.- From the graph we know that

C (1, 1)

radius = 4

Equation of a circle

(x - h)² + (y - k)² = r²

Substitution

(x - 1)² + (y - 1)² = 4²

Simplification

(x - 1)² + (y - 1)² = 16

5.-

Points

A (-1 , -3.5) C (5, -1) B (0.2, -3)

dAB = $\sqrt{(0.2 +1)^{2}+ (-3 + 3.5)^{2}}$

dAB = $\sqrt{(1.2)^{2} + (0.5)^{2}}$

dAB = $\sqrt{1.44 + 0.25}$

dAB = $\sqrt{1.69}$

dAB = 1.3

dBC = $\sqrt{(0.2 - 5)^{2} + (-3 + 1)^{2}}$

dBC = $\sqrt{(-4.8)^{2}+ (-2)^{2}}$

dBC = $\sqrt{23.04 + 4}$

dBC = $\sqrt{27.04}$

dBC = 5.2

Ratio $\frac{AB}{BC} = \frac{1.3}{5.2}$

Plzzzz help don’t understand

Diano4ka-milaya [45]

5s + 5l = 155, 10s + 12l = 346

Solve for s in the first equation.

5s = 155 - 5l

s = 31 - l

Substitute s into the second equation.

10(31 - l) + 12l = 346

310 - 10l + 12l = 346

310 + 2l = 346

2l = 36

l = 18

Substitute l into the first equation.

5s + 5(18) = 155

5s + 90 = 155

5s = 65

s = 13

s = 13, l = 18

Can yall help my friend plzz

GarryVolchara [31]

Step-by-step explanation:

The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.

If a and b are legs, and c is the hypotenuse, then a2 + b2 = c2.

Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.
