Answer:

At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

Step-by-step explanation:

At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F

When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F

Elevation after the submarine dove = -502.5 - 115 = -617.5 feet

This negative sign represents the elevation below the sea level.

And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}

                                              = \frac{253}{4}-\frac{11}{5}

                                              = \frac{1265-44}{20}

                                              = \frac{1221}{20}

                                              = 61\frac{1}{20}°F

Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F

The required expression is y = 0.01x +  58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.

It is the relationship between sets of values. e g y=f(x),

Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as  y = - 0.01x +  58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
                      = 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F

Thus, the required expression is y = 0.01x +  58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

Answer:

C

Step-by-step explanation:

I substituted the x value with the different options. I kept doing that until the equation made sense.

Answer:

b) x = 7

Step-by-step explanation:

16+5x = x+12

Subtract 16 from both sides

5x = x+28

subtract x from both sides

4x = 28

divide 4 from both sides

x = 7

Step-by-step explanation:

a^2 + b^2= c^2

5^2+ 12^2 =c^2

25+ 144= 169 =c^2

square root 169

C= 13

Answer:

13

Step-by-step explanation:

Pythagorean Theorem :

a^{2} + b^{2} =c^{2}

replace a and b

5^{2} + 12^{2} =c^{2}

25+144=c^{2}

169=c^{2}

Step-by-step explanation:

1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5  cups of water, not 3.

3 is too little

2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.

As the given reasoning 3 cups of water is very less than both the statements are not appropriate.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given reasoning in the question,

1. 2 cups of water to 5 cups of cornmeal. Instead of 3, you would use 287.5 cups of water if you used 115 cups of cornmeal.

2. If you are using 5 cups of water for every 3 cups of cornmeal, you would need 6.5 cups of water, which is not a particularly high quantity.

Answer:

The answer is 14.1

Step-by-step explanation:

16.4+-2.3=14.1

-2.3 isnt large enough to make 16.4 a negative.

The new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

An architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards.

Let new width be x:

x = old width + (change in width)

Change in width = -2.3

x = 16.4 + (-2.3) = 14.1 yards

Thus, the new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

Answer:

Let's add the fractions first and then we can estimate the sum.

= 31/4 + 17/3 + 8/18

change to common denominators

= 279/36 + 204/36 + 16/36

add numerators only

= 499/36 or 13 31/36 or 13.86

ANSWER: (B) 13 is the best estimate of the answer. Normally we round up to 14 with a number like 13.86, but since that is not a choice, we can estimate 13 as the answer.
