Given allowable stresses in steel and concrete of 150MPa and 12MPa, respectively, the maximum bending moment that the section can carry can be determined as follows:

Assuming the section is made up of steel and concrete, it is essential to consider the stresses on both materials. By considering the material properties of the section, the overall strength of the section can be obtained.

Therefore, the bending moment that a section can carry can be given by the formula:

M = σ_s * Z_s + σ_c * Z_c

Where: M = Maximum bending moment that the section can carry

           σ_s = Maximum allowable stress in steel

          Z_s = Section modulus of steel

          σ_c = Maximum allowable stress in concrete

           Z_c = Section modulus of concrete

Therefore, the maximum bending moment that the section can carry = 150*Z_s + 12*Z_c

To determine the section modulus of the steel and concrete, we can use the formula:

Z = I/y

whereZ = section modulus

          I = Moment of Inertia of the section

         y = distance of the neutral axis to the extreme fibre

By determining the section modulus of the steel and concrete, the maximum bending moment that the section can carry can be calculated.

Answer:

the answer is 4160

Step-by-step explanation:

because if you subtract 5400 by the money you worked for that is your sum yw xx.

Answer:

Step-by-step explanation:

We have to subtract the amount of money that you have earned by the amount of money that the car costs.

$5400-$1240 is $4160

So you need $4160 more money to buy the car

(Good luck getting that much money XD)

If a card is drawn from a standard deck and replaced. after the deck is shuffled, another card is pulled. Then the probability that the first card drawn is a heart and the second card is a spade is 1/16.

The probability of drawing a heart on the first card is 1/4 since there are 13 hearts out of a total of 52 cards in a standard deck.

After replacing the card and shuffling the deck, the probability of drawing a spade on the second card is also 1/4 since there are 13 spades out of a total of 52 cards in the deck (assuming the deck is well-shuffled).

To find the probability of both events happening (drawing a heart and then a spade), we multiply the individual probabilities together:

Probability = (1/4) * (1/4) = 1/16

Therefore, the probability that the first card drawn is a heart and the second card is a spade is 1/16.

Viola drove 170 meters up the hill that makes an angle of 6° with the horizontal. We are to find what horizontal distance she has covered.

Let us say the horizontal distance she has covered is x meters. From the given information, we know the length of the inclined plane, which is 170 meters. Also, the angle of inclination is 6°. Hence, we know the value of opposite side and the hypotenuse.The horizontal distance she has covered is the adjacent side.Using the trigonometric formula of the tangent function, we get:

tan 6° = opposite/adjacent

tan 6° = x/170 x = 170

tan 6° Using a scientific calculator, we get

:x = 17.8 meters (nearest tenth of a meter).

Hence, the correct answer is option (d) 17.8 meters.

Viola has covered 17.8 meters horizontally.

Answer:

112

Step-by-step explanation:

angle = 1/2(sum of Intercepted Arcs)

BFE = 1/2( 72+152)

       = 1/2 ( 224)

      = 112

The correct answer is option D. Solution: x < -5 or x > -1, and the correct graph would have open circles at -33 and -29 with shading to the left of -33 and to the right of -29 on a number line.

To solve the inequality |x+31 > 2|, we need to consider two cases: when the expression inside the absolute value is positive and when it is negative.

Case 1: x+31 > 2

In this case, we can solve the inequality by subtracting 31 from both sides:

x + 31 - 31 > 2 - 31

x > -29

Case 2: -(x+31) > 2

To solve this case, we need to flip the inequality sign when multiplying or dividing by a negative number:

x + 31 < -2

x < -33

The solution to the inequality is x < -33 or x > -29.

Now, let's analyze the given answer choices and identify the correct solution and graph:

A. Solution: x < -5 or x > -1

This answer choice does not match the solution we derived, so it is incorrect.

B. Solution: x > -5 and x < -1

This answer choice does not match the solution we derived, so it is incorrect.

C. Solution: x > 1 and x < 5

This answer choice does not match the solution we derived, so it is incorrect.

D. Solution: x < -5 or x > -1

This answer choice matches the solution we derived (x < -33 or x > -29), so it is correct.

Based on the correct solution, the graph would have an open circle at -33 and -29 on a number line, indicating that the values are not included in the solution set. The line would be shaded to the left of -33 and to the right of -29.

The correct answer is option D. Solution: x < -5 or x > -1, and the correct graph would have open circles at -33 and -29 with shading to the left of -33 and to the right of -29 on a number line.

The first term of an arithmetic progression whose second term is -5  and third term is 12 is  -22.

An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. A sequence -

a₁ , a₂, a₃ , a₄ ...... aₙ

will be an arithmetic progression if -

a₂ - a₁ = a₃ - a₂ = a₄ -  a₃ = d (constant) is called common difference of A.P. and a₁ = 'a' as the first term.

Given is the second term of an arithmetic sequence which is -5 and the third term is 12.

We can calculate the nth term of an A.P. using the formula -

a[n] = a + (n - 1)d

Now -

a[2] = -5

a + (2 - 1)d = -5

a + d = - 5                ... [1]

and

a[3] = 12

a + (3 - 1)d = 12

a + 2d = 12                .... [2]

Expanding equation [2] further, we get -

(a + d) + d = 12

- 5 + d = 12

d = 17

Then -

a + d = -5

a = - 5 - d

a = -5 - 17

a = - 22

Therefore, the first term of an arithmetic progression whose second term is -5  and third term is 12 is  -22.

In other words, any two angles whose sum is 90 when

their measures are added together are complementary angles.

Take a look at the angles below.

Do they have the same value?

Well obviously no, they don't so they aren't congruent.

Answer:

Step-by-step explanation:

Given the following :

Rita's tank contains =7.8 gallons of water

Filling rate = 2.1 gallons per minute

Wendy's tank contains = 97.8 gallons

Drain rate =. 0.9 gallons per minute

After how many minutes will both contain the same amount of water.

Let number of minutes = m

Rita is filling :

Initial + increase

7.8 + 2.1m ----(1)

Wendy is emptying:

Initial - decrease

97.8 - 0.9m - - - (2)

Equate both ;

(1) = (2)

7.8 + 2.1m = 97.8 - 0.9m

2.1m + 0.9m = 97.8 - 7.8

3m = 90

m = 90 / 3

m = 30 minutes
