Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.

Simplify the expression in (-30) + 70 + (-9) + 2 +(-0.1) + 0.3 = 2 + (-9) + 70 + (-0.1) + 0.3 + 70

Answers

Answer:

When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.

Step-by-step explanation:

Answer:

[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]

40 + (-7) + 0.2

33 + 0.2

33.2°F

The temperature of the water dropped to 33.2°F after Raul added the ice cubes.

Answers

Answer:

B,b‒a is a positive.

Step-by-step explanation:

if a=‒x x=rational number

b=x

let's see these by examples

A,a‒b is a positive, ‒x‒x=‒2x (the answer is negative) so this is wrong

B,b‒a is a positive, x‒(‒x)=x+x=2x (the answer is positive)so this is correct answer

C,b+(‒a) is a negative,x+‒(‒x)=x‒(‒x)=x+x=2x(the answer is positive)so this is also wrong

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?
12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12

Answers

Answer:

Your answer would be C.

Step-by-step explanation:

The expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time.

As we know,

The distance = speed x time

Speed is constant

distance ∝ time

3/4 ∝ 12

1 ∝ x

Here x is the distance traveled each minute

3/4 = 12/x

x = 12/(3/4)

1/4 = 4/x

x = 16 miles

Thus, the expression that can be used to determine the distance he walked each minute is x = 12/(3/4) miles option (A) is correct.

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.

Answers

Step-by-step explanation:

y-b=m(x-a)

y--10=1/6(x--6)

y+10=1/6(x+6)

6y+60=1(x+6)

6y+60=1x+6

6y=1x-54

y=1/6x-54/6

y=1/6x-9

The equation of line is y= 1/6x - 9.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

slope= 1/6

and, passes through (−6,−10)

Now, using slope intercept form

y- a =m (x- b)

y - (-10)= 1/6(x -(-6))

y + 10= 1/6( x + 6)

y + 10 = 1/6x + 1

y= 1/6x - 9

Hence, the equation of line is y= 1/6x - 9.

Answer:

b please mark me as barinlest

Step-by-step explanation:

Solve this equation y=bd-6, for b

Answers

To solve this equation, you would need to isolate b. To do this, first you would add six to both sides. Then, to get rid of the d, you would divide both sides by d since that is the opposite of multiplication. So, the answer would be

b = y-6
———
d

Answer: [tex]b = \frac{y+6}{d}[/tex]

Step-by-step explanation: To isolate b, begin by adding 6 to both sides

y=bd-6

y + 6 = bd - 6 +6 This "cancels" 6 on the right leaving

y + 6 = bd Divide both sides by d

(y + 6)/d = bd/d This cancels d on the right leaving

(y + 6)/d = b To neaten this up rewrite (using the equations tool below)

[tex]b = \frac{y+6}{d}[/tex]

ANSWER PLEASEEEEE TYYY For a program to be successful, readiness for training should be assessed on two dimensions: employee characteristics and work environment. The employee characteristics that are relevant to training are the ability to learn the subject matter, attitudes toward training, and motivation to learn. Even if these are present, however, training will not be effective unless there is a positive work environmentan environment that encourages learning and eliminates obstacles for trainee success. An important characteristic of employee readiness is having basic learning skills, especially cognitive ability that includes using written and spoken language, solving math problems, and using logic to solve problems. If employees lack certain basic skills, they may have to attend some remedial classes before participating in job-related training. Seeing potential benefits from training programs may increase employee motivation to participate. Readiness for training also depends on work environment characteristics called situational constraints and social support. Constraints can include the limits of training's effectiveness from within the organization, such as lack of money or lack of time for training and practicing. Social support refers to the ways that the organization encourages training by expressing positive attitudes toward its training programs. The goal of this activity is to evaluate employee readiness for training.Read each statement, then select the appropriate category 1.

Experiment 1: A study is done to determine which of two fuel mixtures allows a rocket to travel farther over a period of time. Rocket A, which requires additional equipment to keep it stable, is used to test one fuel mixture, and rocket B is used to test the other. Both rockets are identical aside from their mass. The results indicate that rocket B traveled farther than rocket A over the same period of time. Experiment 2: A double-blind experiment is performed to test whether a new drug is effective in lowering blood pressure. A random sample of subjects with high blood pressure is assigned to two groups. One group receives the new drug and the other group does not. Neither group is permitted to take any other medications during the experiment or to change their lifestyles in any way. The results of the experiment show that the drug is effective in lowering blood pressure. Identify the experiment in which confounding occurs and the reason for its occurrence.a. Neither experiment has a confounding variable.b. Experiment 1 has a confounding variable related to the fuel mixtures. Varying the fuel mixture could skew the results of the study and should be kept constant.c. Experiment 2 has a confounding variable related to the type of experiment. A double-blind experiment may increase the risk of the placebo effect and possibly skew the results.d. Experiment 1 has a confounding variable related to the mass of the rockets. Any variation in mass may cause a discrepancy in the distance traveled.e. Experiment 2 has a confounding variable related to the subjects used. Choosing a sample of subjects with high blood pressure instead of individuals with different blood pressure levels may confuse the results.
