THE ANSWER IS 1/4

Step-by-step explanation:

Answer:

the anwser is 242

Step-by-step explanation:

I dont see a q anywhere but you would sub p and 9 and do the equation so times 10 and 9 and then distribute 22 or in your calculator jus enter 22(90-79) and you would get 242

0.85(a + 60) ≤ 85

0.85a + 51 ≤ 85

-51 on both sides

0.85a ≤ 34

/0.85 on both sides

a ≤ 40

Answer:

a ≤ 40

Answer:

A, y-intercept = (0,24)

Step-by-step explanation:

The y intercept is the one without a variable. You have to solve to find it in the other options.

Answer:

The first choice would be the best one.

Step-by-step explanation:

The y intercept occurs when x = 0 of the given polynomial.

All 3 answers will give you the correct answer. The y intercept is (0,24)

but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.

2x^2 when x = 0 is 0

16x when x = 0 is 0.

That only leaves m(0) = 24 found just by looking at it.

The second one also works. 2 (0+4)^2 -  8 = 32 - 8 = 24

And the third one as well 2(6)(2) = 24

Answer:

4

Step-by-step explanation:

4 * 4 * 4 = 64

Notice that the second polynomial is subtracted from the first.

It's important to understand that the minus sign outside the

second set of parenthses can be thought of as a -1.

So we need to distribute the -1 through each of

the terms in the second set of parenthses.

So our problem will now look like 5x² + 25x + 30 - 3x² - 6x - 3.

Now, we combine like terms.

So we have 2x² + 19x + 27.

Answer:

x = 15

Step-by-step explanation:

If she ran 5 miles on Friday, and 20 in the whole week, you can make the equation:

5 + x = 20

x = 15

Answer:

If you subtract your vertex angle (50°) from 180°. You get 130°. This is now the degrees for both of your base angles.

Step-by-step explanation:

³√512 = ³√(8³) = 8.

³√(-1728) = ³√(-12³) = -12.

√144 - ³√(-8)

= 12 - ³√(-2³)

= 12 - (-2)

= 14.

1 3/10

Answer:

2-4+4=0

Step-by-step explanation:

Answer:

The correct answer is A

Step-by-step explanation:

20% x 12 = 2.4

2.4 + 12 = 14.4

20% x 8 = 1.6

1.6 + 8 = 9.6

Answer:

ok so

Step-by-step explanation:

8x + 7 + 7x - 2=90=>

=> 15x+5= 90

=> 15x=90 - 5=>

=> 15x =85= x= 5.6666...

Hey there!

“8x + 7 + 7x – 2 = 90”

• FIRST: COMBINE your LIKE TERMS

(8x + 7x) + (7 – 2) = 90

‘8x + 7x = 15x’

‘7 – 2 = 5x’

“15x + 5 = 90”

• SECOND: SUBTRACT by 5 on BOTH SIDES

15x + 5 – 5 = 90 – 5

CANCEL out: 5 – 5 because that gives you 0

KEEP: 90 – 5 because it helps us solve for your x-value

‘90 – 5 = 85’

NEW EQUATION:

“15x = 85”

• THIRD: DIVIDE by 15 on BOTH SIDES

15x/15 = 85/15

CANCEL out: 15/15 because that equals 1

KEEP: 85/15 because it gives us our x-value

Reduce: 85/15 and it gives us: x

Answer: x = 17/3 ☑️

Good luck on your assignment and enjoy your day!

We know he traveled 4.8 miles in 3 hours.  However, since the question asks for his speed in miles per hour, we only want to know how far he travels in one hour.  To find this, we just divide 4.8 by three, and find that he is traveling at 1.6 miles per hour.

Answer:

Speed = 1.6

Step-by-step explanation:

[tex]Speed=\frac{Distance}{Time} \\\\Speed = \frac{4.8}{3}=1.6[/tex]

Answer:

42 cm²

Step-by-step explanation:

Length of the shaded rectangle = 7 cm

Width of the shaded rectangle= 7 - (0.5 + 0.5) = 7 - 1

Width of the shaded rectangle = 6 cm

Area of the shaded rectangle = L × W

Area = 7 × 6 = 42 cm²

Answer:

48 percent

Step-by-step explanation:

12 divided by 25 gets you .48 which can be expressed as 48%

Answer:

48%

Step-by-step explanation:

1. Change 12/25 to a fraction with a denominator of 100

25 x 4=100

12 x 4=48

2. Find the percent

48/100= 48%

Answer:

16 1/2 minutes

Step-by-step explanation:

2.8m = 46.2

m = 16.5

Answer:

maybe 16.5

Step-by-step explanation:

divide 46.2 with 2.8 and get 16.5

Answer:

199.75km

Step-by-step explanation:

Step one:

given data

We are told that the time of travel is from

8:36- to 10:57

which is 2 hours 21 minutes

Hence the time taken is 2.35 hours

the speed is 85km/h

Step two:

From the expression

speed= distance/time

85= distance/2.35

distance= 85*2.35

distance= 199.75km

Answer: it traveled a distance of 199.75Km

Step-by-step explanation:

From the question , Let 0836 be 8:36

and 1057 be 10:57

Time of departure= 8:36

Time of arrival = 10:57

Time traveled = 10:57- 08:36= 2 Hours 21 minutes

changing trhe time to hours becomes 21/60 = 0.35 hours + 2 HOURS = 2.35 hours

Step 2

Speed = Distance / Time

Distance = Speed x Time

=85 km/hr x 2.35 hours

=199.75Km

Answer: 3) x = 87°; y = 93°; z = 63°

Step-by-step explanation:

x + 33 + 60 = 180 since they form a triangle.

x + 93 = 180

Subtract 93 from both sides

x = 87°

x and y are linear pairs so they're supplementary.

y + x = 180

y + 87 = 180

Subtract 87 from both sides

y = 93°

z + y + 24 = 180 since they also form a triangle

z + 93 + 24 = 180

z + 117 = 180

Subtract 117 from both sides

z = 63°

Answer:

Step-by-step explanation:

-3/4 and 5/8

bc it's a negative number and not a positive number. When numbers are negative, the number keeps getting smaller and smaller. And when you add a positive number to a negative number, then the number will start increasing it's value.

Given:

[tex]\sigma_A=3[/tex]

[tex]n_A=6[/tex]

[tex]\sigma_B=5[/tex]

[tex]n_B=4[/tex]

[tex]\overline{x}_A=\overline{x}_B[/tex]

To find:

The variance. of combined set.

Solution:

Formula for variance is

[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}[/tex]      ...(i)

Using (i), we get

[tex]\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}[/tex]

[tex](3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]

[tex]9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]

[tex]54=\sum (x_i-\overline{x}_A)^2[/tex]

Similarly,

[tex]\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}[/tex]

[tex](5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]

[tex]25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]

[tex]100=\sum (x_i-\overline{x}_B)^2[/tex]

Now, after combining both sets, we get

[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}[/tex]

[tex]\sigma^2=\dfrac{54+100}{6+4}[/tex]

[tex]\sigma^2=\dfrac{154}{10}[/tex]

[tex]\sigma^2=15.4[/tex]

Therefore, the variance of combined set is 15.4.

Answer:

  (a)  4x+89.95=628.35; x = $134.60

Step-by-step explanation:

The total cost (628.35) is the cost per cavity (x) times the number of cavities (4), added to the flat fee (89.95). The equation for that is ...

  4x +89.95 = 628.35

The solution to that is ...

  x = (628.35 -89.95)/4 . . . . . subtract the constant, divide by 4

  x = 134.60
