Answer:

Here are some examples:

[tex] \sqrt{9}, 18/3, 15, -6, 1.2, 0 [/tex]

i think it would be 9.6 inches because 8 feet is 96 total inches so you could divide that by 10 getting every inch on the model to represent 9.6 inches on jeffs truck totaling at 96 inches or 8 feet

Answer:

the first question the answer is: Answer. A + 2A + 3A = 180 degrees ( total for all 3 angles in any triangle). This one is a right triangle since one of the angles is 90 degrees. did that make any sense? lol

Answer: - 4

Step-by-step explanation:

Given that A = - 4, B = 3

According to the instruction :

Raise -2 to the double of b and divide the result by the quadruple of a. A=-4 and B =+3

Raise - 2 to the double of b ;

Result = (-2)^(2*3) = (-2)^6 = 64

Divide result by quadruple of a

a = - 4 ;

Quadruple of 'a' means 4 times as many as 'a' = '4 * a' quadruple of a = (-4) * 4 = - 16

= (-2)^6 / -16

64 / - 16

64 / - 16 = - 4

Answer:

160 athletes

Step-by-step explanation:

Let the total number of athletes in the meet be x

Given that 24 athletes who  threw the shot put at a track and field meet are 15/100 of all the  athletes in the meet .

If we write this in mathematical algebraic expression

15/100 of all the  athletes in the meet = 24

15/100 * x = 24

=> x = 24*100/15 = 24*100/3*5 = 160

Thus, 160 athletes competed in the meet.

Step-by-step explanation:

Let the price before be x

Then the price after is:

Answer:

x = 1

Step-by-step explanation:

6(x+4)=30    (divide both sides by 6)

(x+4) = 30/6

x+4 = 5   (subtract 4 from both sides)

x = 5 - 4

x = 1

Step-by-step explanation: 6(x+4)=30

(Distributive property): 6x+24=30

( Transposition method): 6x=30-24( + becomes -) 6x=6

(Transpose 6 to rhs) x=6/6( since it was multiplication on LHS it becomes division in RHS) x=1

Answer:

m = -3

Step-by-step explanation:

Slope Formula: [tex]m = \frac{y2-y1}{x2-x1}[/tex]

Simply plug in our coordinates to find slope:

m = (11 - 2)/(5 - 8)

m = 9/-3

m = -3

Answer:

"BOB" gave back 1000 that would be 928439 - 1000 = 927439(BOB has)

"BOB" gave back 1000 to Milly.. 29924827134702 + 1000 = 2.9924827(MILLY has)

Step-by-step explanation:

well, first, if "BOB" gave back 1000 that would be 928439 - 1000 = 927439, so "BOB" now has 27439. and now, "BOB" gave back 1000 to Milly sooo now it is 29924827134702 + 1000 = 2.9924827 (e+13) soooo ya thats it

hope this helped LOL

Step-by-step explanation:

From the graph we notice that the minimum of the function 1 is -1

From the table we notice that the minimum of the second function is 2

so the function #2 has a greater minimum

The function is x²+3x-4

Derivate it and solve the equation y'=0

y'= 2x+3

y'=0

2x+3=0

2x= -3

x = -3/2

Derivate it again:

y"= 2> 0⇒ so the function reaches the minimum at -3/2

the image of -3/2 is :

y= (-3/2)²+3*(-3/2)-4 = -6.25

so the answer is

#3<#1<#2

Answer:

B. The Range is the set of real numbers greater than or equal to zero

C. The Domain is the set of all real numbers .

Step-by-step explanation:

The Domain is the set of real numbers for which the function is defined. In this case, the Domain is the set of all real numbers .

The Range is the set of real numbers that are connected to the elements of the domain. In this case, you see that only real numbers above (or in the) x-axis are connected to the x-values of the domain. Then another answer to check is;

B. The Range is the set of real numbers greater than or equal to zero.

Answer:

y = 1/6x - 3

Step-by-step explanation:

Step 1: Find the slope

Take the negative reciprocal of the other slope

m = 1/6

y = 1/6x + b

Step 2: Find b

-2 = 1/6(6) + b

-2 = 1 + b

b = -3

Step 3: Rewrite perpendicular linear equation

y = 1/6x - 3

Answer:

10 cm

Step-by-step explanation:

Since WX is tangent, it is a right angle

VWX is a right triangle, so we can use the Pythagorean theorem

a^2+b^2 = c^2

6^2 + 8^2 = VX ^2

36+64 = VX ^2

100 = VX ^2

Take the square root of each side

sqrt(100) = sqrt(  VX ^2)

10 = VX

Answer:

10 cm

Step-by-step explanation:

Since WX is tangent to the circle V, by definition, WX ⊥ WV.

So, we've established that ΔWXV is a right triangle. This means that we can apply the Pythagorean Theorem, which states that for a triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, we have a = WV = 6 and b = WX = 8, so:

a² + b² = c²

6² + 8² = 36 + 64 = 100

c² = 100

c = √100 = 10

Therefore, VX = 10 cm.

Answer:

The answer is A.

Step-by-step explanation:

We need to find the least amount of paper needed to wrap the entire cylinder. Therefore, we simply need to find the surface area of the cylinder.

Recall the formula for the surface area of a cylinder:

[tex]SA=2\pi r^2+2\pi rh[/tex]

We know the diameter is eight inches, so the radius is four inches. We also know the height is 12. Using 3.14 for π, substitute:

[tex]SA=2(3.14)(4)^2+2(3.14)(4)(12)[/tex]

[tex]SA\approx 401.92\text{ in}^2[/tex]

Our answer is A.

Answer:

It's A

Answer:

other leg = 8.944271910

Step-by-step explanation:

If you are trying to figure out the other leg you have to use pythagorean therom:

c^2 - a^2 = b^2

(12)^2 - (8)^2 = b^2

144 - 64 =b^2

80 = b^2

√80 = b

8.944271910 = b

[tex]h(x)=3x-7[/tex]

And we are given that [tex]h(x)=0[/tex] and want to find the value of x. Set h(x) to 0 and we get the equation:

[tex]3x-7=0[/tex]

Add both sides by 7

[tex]3x=7[/tex]

Divide both sides by 3

[tex]x=\dfrac{7}{3}[/tex]

This is the answer (as an improper fraction). Let me know if you need any clarifications, thanks!

[tex]\text{Plug in 0 to h(x) and solve:}\\\\0=3x-7\\\\\text{Add 7 to both sides}\\\\7=3x\\\\\text{Divide both sides by 3}\\\\\frac{7}{3}=x\\\\\boxed{\frac{7}{3}=x}[/tex]

Answer:

9

Step-by-step explanation:

One Decimal Place Rule #3: If the last digit in 8.99 is 5 or more and the second to the last digit in 8.99 is 9, then remove the last digit, make the second to last digit 0, and add 1 to the number to the left of the decimal place.

Hey there! :)

Answer:

(1, 0).

Step-by-step explanation:

Convert from standard form to vertex form by completing the square:

y = x² - 2x + 1

Move 1 to the other side:

-1 = x² - 2x

Complete the square. Remember to add to both sides:

-1 + (1) = x² -2x + 1

Simplify:

0 = (x - 1)²

The function in vertex form is:

y = (x - 1)²

Therefore, the vertex is:

(1, 0).

Answer:

A)Only Line A is well placed line of best fit

Step-by-step explanation:

Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line

The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit

By considering both the given graphs

We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit

So,Option A is true

A)Only Line A is well placed line of best fit

Answer: a) only line A is a well placed line of best fit
