Help!! For this question I got 254.34 as my final answer but when I checked my answer it told me I was wrong?

Answer:

No

Step-by-step explanation:

3rd option should be changed to "will not".

9514 1404 393

Answer:

Step-by-step explanation:

Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.

  6 + 3x ≤ 15

  3x ≤ 9 . . . . . . . . . subtract 6 from both sides

  x ≤ 3 . . . . . . . . . . divide by 3

This is "x is less than or equal to three."

  2 is less than 3 so will meet Mari's goal

  3 is equal to 3, so will meet Mari's goal

  4 is not less than or equal to 3, so will not meet Mari's goal

Answer:

Hey Natalia,

I suppose A is just what is on the left and B what 8s on the right

so for 5) it would be

A = 6

and

B = 3

Answer:

Step-by-step explanation:

1.6/x=3/8

do cross multiplication

x*3=6*8

x=48/3

x=16

2.b/8=3/4

do cross multiplication

b*4=8*3

b=24/4

b=6

4.n/8=35/7

do cross multiplication

35*8=7*n

280=7n

280/7=n

40=n

Answer:

AD = 6

Step-by-step explanation:

If a radius is perpendicular to a chord, then it bisects the chord.

Here XB is the radius, AC is the chord. Given XB and AC are perpendicular to each other. Therefore, XB bisects AC at D.

So,

    [tex]AD = \frac{1}{2} \times AC = \frac{1}{2} \times 12 = 6[/tex]

is this an algebra class? if so it just

11.50x + 16y = 20.25

Answer:

3 + 9 ÷ (9 - 6)

Step-by-step explanation:

3 + 9 ÷ (9 - 6) = 3 + 9 ÷ 3 = 3 + 3 = 6

OR  

3

Step-by-step explanation:

first you work out what is in the brackets

that is  

1

3

÷

1

6

to give you 2 as you answer

second step rewrite the whole question replacing two in the place of  

1

3

÷

1

6

so you will have  

3

4

+

2

−

(

−

1

2

)

thirdly open the brackets with the negative sign outside the bracket that is:  

−

(

−

1

2

)

so that you get  

+

1

2

(or  

1

, basically)

lastly rewrite the whole question

so you will have  

3

4

+

2

+

you can keep that solution, or you can change it from improper fraction to a mixed number

if you use long division,

Step-by-step explanation:

Circle A is located at (6, 5) and has a radius of 4 units. What is the equation of a line that is tangent to circle A from point C (2, 8)?

x = 2

y = −0.75x + 9.5

y = 1.33x + 1.66

x = 8

Answer:

[tex]Change = \$36[/tex]

Step-by-step explanation:

Given

See attachment for line plot

[tex]Amount = \$100[/tex]

Required

Determine the change

First, we calculate the amount represented by the line plot

[tex]Amount (Plot) =10+12+12+14+16[/tex]

[tex]Amount (Plot) =64[/tex]

The change from $100 is then calculated as:

[tex]Change = Amount - Amount (Plot)[/tex]

[tex]Change = \$100 -\$64[/tex]

[tex]Change = \$36[/tex]

Answer: $1.75

Steps: 30%=0.3

0.3 x 2.50 = 0.75

2.50 - 0.75 = 1.75

Answer:

Step-by-step explanation:

tan is the same thing as sin/cos. therefore,

[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]

[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so

[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.

Answer:

(16, 6 )

Step-by-step explanation:

Basically you are expressing the points (dots ) in coordinate form

Locate x = 16 on the x- axis ( between 14 and 18 )

Then go vertically up to the point at (16, 6 )

Answer:

[tex]\sqrt[3]{x^2}[/tex]

Step-by-step explanation:

x ^ (5/6)   / x ^ (1/6)

We know that a ^b  / a^ c = a^ (b-c)

x^ ( 5/6 - 1/6)

x^ (4/6)

x^ ( 2/3)

[tex]\sqrt[3]{x^2}[/tex]

Answer: 8 3/4

Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

Answer:

Use the referent of an adult stride (about 1 yard) to measure the dimensions of the area that will be covered by sod. Use the dimensions to calculate the area in square yards.

Step-by-step explanation:

This seems to be a relatively vague question, but it was requested so I'll try my best.

There's practically no way to accurately measure the area to be covered by sod without using a reference. I couldn't help but notice the list of references above the question, and I presume they are correlated. Since the length of an adult stride is 1 yard, you can use an adult stride as a reference to relatively accurately measure the dimensions of the area that needs to be covered. The method to find the area varies with the shape of the area, but assuming you can accurately find the area, this is a plausible way to estimate the area needed to be covered by sod. As an alternative, since the question stipulates sod can only be purchased in square yards or square meters, you can use a doorway (about 2 meters) in the list of references above the question to also measure the dimensions of the area. This is less practical because an adult stride is more mobile than a door.

Hey there!

1. How to find f(5)?

2. Substitution and Evaluate

[tex] \large{f(5) = - 4( {5})^{2} + 6(5) - 4}[/tex]

Remember to follow the PEMDAS/BODMAS rules! Exponent comes before multiplication.

[tex] \large{f(5) = - 4(25) + 30 - 4} \\ \large{f(5) = - 100 + 30 - 4} \\ \large{f(5) = - 74}[/tex]

Answer:

4

Step-by-step explanation:

(24+4) ÷ 2 = (24 ÷ 2) + (4 ÷ 2)

28÷2 = 14

Check:

24÷2 = 12

4÷2 = 2

12+2=14

Answer:

The answer is 4.

Step-by-step explanation:

(24 + 4) ÷ 2 = (24 ÷ 2) + (x ÷2)

=28 ÷ 2 = 12 + (x÷2)

14 = 12 + (x ÷ 2)

14 - 12 = x ÷ 2

2 = x ÷ 2

2 × 2 = x

x = 4
