What was Veronica's speed if she drove 475 miles in 6 1/4 hours?

Answer: 76 mph

Step-by-step explanation: speed is distance divided by time so 475 : 6.25 = 76 (mph)

**Answer:**

76 mph

**Step-by-step explanation:**

To find the answer, you would divide the miles she drove: 475 by the amount of time it took to get there: 6 1/4 hours. Convert the fraction to a decimal: 1/4= .25 so your problem would look like this...

475 / 6.25 = 76

What does x equal?

2x + 5x – 4= 17

Answer:

x = 3

Step-by-step explanation:

2x + 5x - 4 = 17

Combine like terms

7x - 4 = 17

Add 4 to both sides

7x = 21

Solve for x

x = 21/7

x = 3

Jace has consumed 1,500 calories so far today. He has also burned off 400 calories at the gym. He would like to keep his daily calorie total to 1,900 calories per day. How many calories does he have left to consume for the day? Is 1,100 a viable solution to this problem?

Yes; 1,100 is less than 1,500.

No; 1,100 is more than the 400 he burned off at the gym.

No; 1,100 will cause him to exceed 1,900.

Yes; 1,100 is less than 1,900.

**Answer:**

Option 3

**Step-by-step explanation:**

If he burned off 400 calories from 1500 consumed calories, he has 1100 consumed calories. 1900 - 1100 = 800 calories left to consume.

While option 2 also says no, it's not the right reason.

The calories left to consume for the day is **800 calories.**

**No, 1,100 will cause him to exceed 1,900.**

Given,

Jace has consumed **1,500 calories** so far today.

He has also burned off **400 calories** at the gym.

He would like to keep his daily calorie total to **1,900 calories** per day.

We need to find how many calories he has left to consume for the day.

And see which option is the best choice.

We have,

Calories consumed in a day = **1500**

Burned calories = **400**

Calories to keep in a day = **1900**

Find the **Calories** **left**

= 1500 - 400

= **1100**

Find how many calories need to be consumed to keep **1900 calories.**

= Calories needed to keep in a day - calories remaining after burned

= 1900 - 1100

= **800 **

We see that the calories left to consume is **800 calories.**

So 1100 is **not a viable solution**. It will cause him to **exceed 1,900.**

Thus,

The calories left to consume for the day is **800 calories.**

**No, 1,100 will cause him to exceed 1,900.**

What is the value of X?

Answer:

5 * sqrt(3)

Step-by-step explanation:

The sine of 60 degrees is equal to x/10 because x is opposite to it and 10 is the hypotenuse. Since the sine of 60 degrees is equal to sqrt(3)/2, sqrt(3)/2 = x/10. Because 5sqrt(3)/10 = sqrt(3)/2, 5sqrt(3)/10 = x/10 and therefore 5sqrt(3) = x.

The answer would be 5 and something to help you when doing these questions is using sin tan cos. If you search it up it shows which one to use when it comes to equations like this. And when you find it you enter it in your calculator. Since you need the opposite your gonna use COS. Cos(60) = 10 and then your gonna put an x under cos(60) as if it was a fraction and do cross multiply. And that’s how you will get 5.

Compare negative square root of 7 and -3.12345

**Answer: Square root of negative 7 is greater than -3.12345**

**Step-by-step explanation: Since the square root of -7= 2.64575131 i (A positive number) Then it's greater, since the positive number is always greater than the negative numbers, because the negative numbers are further below zero than the positive number, if there is a number below the zero and a number above the zero, the one above the zero is greater, because it's a positive number, the one below 0 is negative.**

**Answer:**

Ada is correct.

**Step-by-step explanation:**

Problems with Naman:

Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:

**P**arenthesis

**E**xponents (& Roots)

**M**ultiplications

**D**ivision

**A**ddition

**S**ubtraction

~

The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.

Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.

If f(x) = x (ln x), find f'(x).

A. e^(x + 1)

B. 1 + ln x

C. 1 + e^x

D. (ln x)^2 + x

**Answer:**

[tex]f'(x)=1+\ln x[/tex]

**Step-by-step explanation:**

[tex]f'(x)[/tex] is notation for the first derivative of [tex]f(x)[/tex].

Recall the product rule:

[tex](f\cdot g)'=f'\cdot g+g'\cdot f[/tex]

Therefore, we have:

[tex]\displaystyle \frac{d}{dx}(x\ln x)=\frac{d}{dx}(x)\cdot \ln(x)+\frac{d}{dx}(\ln x)\cdot x[/tex]

Note that:

[tex]\displaystyle \frac{d}{dx}(x)=1,\\\\\frac{d}{dx}(\ln x)=\frac{1}{x}[/tex]

Simplify:

[tex]\displaystyle \frac{d}{dx}(x\ln x)=1\cdot \ln x+\frac{1}{x}\cdot x, \\\\\frac{d}{dx}(x\ln x)= \ln x+1=\boxed{1+\ln x}[/tex]

The derivative is:

[tex] \bold{f(x) \: = \: x \: \times \: (In(x))}[/tex]

[tex] \bold{f'(x) \: = \: \frac{d}{dx} (x \: \times \: In(x))}[/tex]

[tex] \bold{f'(x) \: = \: \frac{d}{dx} (x) \: \times \: In(x) \: + \: x \: \times \: \frac{d}{dx} (In(x))}[/tex]

(-4+ 8x) +3>

What is the solution to the inequality

-4?

**Step-by-step explanation:**

if I understand the typed information here, we have

(-4 + 8x) + 3 > -4

so, I am looking at that :

-4 + 8x + 3 > -4

let's first add 4 on both sides

8x + 3 > 0

then subtract -3 on both sides

8x > -3

and finally divide both sides by 8

x > -3/8

since we never multiplied or divided by a negative number, the inequality sign stays the same.

so, this inequality is true for all x > -3/8

Answer:

You would shade the fourth quadrant (bottom right).

Step-by-step explanation:

Due to the domain and range sets, you're given the facts that x must be greater than or equal to 0, but y is less than or equal to zero. This gives you what quadrant the graph should be in. Since you're not given an equation to follow like y=ax+b, then I can not say that this will give you a line.

The line (y-1)=(2/3)(x+1) contains point (a,-3).

What is the value of a? Show

your work.

**Answer:**

-7

**Step-by-step explanation:**

The line (y-1)=(2/3)(x+1) contains point (a,-3)

=> (-3-1) = (⅔)(a+1)

-4 = (⅔)(a+1(

(a+1)= -4 ÷ ⅔

a + 1 = -4 × 3/2

a+ 1 = -6

a = -6-1

**a**** ****=**** ****-****7**

The **value **of 'a' will be;

⇒ a = - 7.

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

Given that;

The **equation of line** is,

⇒ (y - 1) = (2/3) (x + 1)

And, The point on the line = (a, - 3)

Now,

Since, The **point** on the line = (a, - 3)

Hence, It satisfy the equation of line.

**Substitute **x = a and y = - 3, we get;

⇒ (y - 1) = (2/3) (x + 1)

⇒ (- 3 - 1) = (2/3) (a + 1)

⇒ - 4 × 3 = 2a + 2

⇒ - 12 - 2 = 2a

⇒ 2a = - 14

⇒ a = - 7

Thus, The **value **of a = - 7
