Answer:

14+19=33 33 divided by 23=?

Step-by-step explanation:

triangle with the given side is a right triangle;14mm, 19mm, 23mm ... Use the Pythagorean theorem that only works for right triangles.

Answer:

35

Step-by-step explanation:

There are 3 angles in a triangle

∠1 , ∠2 , ∠3

Of which

∠1 = ∠2

∠3 = 110

By angle sum property

∠1 + ∠2 + ∠3 = 180

∠1 + ∠2 = 180-110

∠1 + ∠2 = 70

∠1 = 70 ÷ 2

=35

∠1 = ∠2 = 35

Hence , 35+35+110 = 180

Answer:

35°, 35°, 110°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

let the equal angles be x , then

x + x + 110 = 180 , that is

2x + 110 = 180 ( subtract 110 from both sides )

2x = 70 ( divide both sides by 2 )

x = 35

the measure of each angle is 35° , 35° , 110°

Answer: C - 4 = 14

Step-by-step explanation: In the expression, "c" is colin's age so, if you subtract 4 years for his age, you get Katie's age, which is 14.

Answer:

No.

Step-by-step explanation:

Assuming 13 is the base. 3 can't be a slope, and 10 can't be a slope because the sids aren't long enough.

Answer: No

Step-by-step explanation:

This cannot form a triangle because the Triangle Inequality states that the sum of any two sides of a triangle must be greater than the other side.

This set of side lengths doesn't satisfy the Triangle Inequality, since 3 + 10 = 13, and 13 is not greater than 13.

In short, this doesn't form a triangle, instead it just forms a straight line.

Answer:

40 miles per hour

Step-by-step explanation:

480 divided by 12 equals 40, your answer

Please give brainliest thanks

The rate in miles per hour -- > miles/hour

      --> 480miles / 12 hours = 40 miles/hour

The rate in hours per miles --> hours/ mile

      --> 12 hours/ 480 miles = (1/40) hours/mile

Option D is correct

Answer:

14

Step-by-step explanation:

The sides of an isosceles right triangle are 1-1- \sqrt{2}. Since the legs are 7\sqrt{2}, we multiply it by \sqrt{2} to get 14.

From the question, we are to determine the number of moles and mass of KMnO₄ needed

From the given balanced chemical equation

5KNO₂ + 2KMnO₄ + 3H₂SO₄ → 5KNO₃ + 2MnSO₄ + K₂SO₄ + 3H₂O

This means 5 moles of KNO₂ is required to react completely with 2 moles of KMnO₄

First, we will determine determine the number of moles of KNO₂ present

From  the given information,

Mass of KNO₂ = 11.4 g

Using the formula,

[tex]Number\ of\ moles = \frac{Mass}{Molar\ mass}[/tex]

Molar mass of KNO₂ = 85.1 g/mol

Therefore,

Number of moles of KNO₂ = [tex]\frac{11.4}{85.1}[/tex]

Number of moles of KNO₂ = 0.13396 mole

Now,

If 5 moles of KNO₂ is required to react completely with 2 moles of KMnO₄

Then,

0.13396 mole of KNO₂ will react completely with [tex]\frac{0.13396 \times 2}{5}[/tex] mole of KMnO₄

[tex]\frac{0.13396 \times 2}{5}[/tex] = 0.053584 mole ≅ 0.0536 mole

Hence, the number of moles of KMnO₄ needed is 0.0536 mole

For the mass of KMnO₄ needed,

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of KMnO₄ = 158.034 g/mol

Therefore,

Mass of KMnO₄ needed = 0.053584 × 158.034

Mass of KMnO₄ needed = 8.468 g

Mass of KMnO₄ needed ≅ 8.5 g

Hence, the mass of KMnO₄ needed to carry out the reaction is 8.5 g

Answer:

(x - 3) is not a factor

Step-by-step explanation:

If (x - h) is a factor of f(x) then f(h) = 0

here

f(x) = x³ - 5x² - 4x + 6 , then

f(3) = 3³ - 5(3)² - 4(3) + 6 = 27 - 5(9) - 12 + 6 = 27 - 45 - 6 = - 24

since f(x) ≠ 0 then (x - 3) is not a factor of f(x)

Answer:

40%

Step-by-step explanation:

6.75 + 1.25 = 8 (Total she just spent)

8 (Total she just spent) + 12 (Total she had left) = 20 (Total she started with)

8/20 = 0.4 = 40%

(Total spent / total she started with = 40%)

Answer:

10 cm

Step-by-step explanation:

Out of that [tex]160 cm^2[/tex], part of it is given by the surface of the top and bottom faces, which have area [tex]2\times 5 cm^2 = 10 cm^2[/tex] each, for a total of [tex]20 cm^2[/tex] . We are then left with [tex]140 cm^2[/tex] of surface from the side area. That area you can imagine as a rectangle of height h (which we need to know) and base [tex]5+2+5+2 cm = 14 cm[/tex] (imagine it as a box opened on a flat surface)

At this point we have [tex]140cm^2 = 14 cm \times h \rightarrow h= 10 cm[/tex]
