Answer:

m-10

Step-by-step explanation:

If it said M decreased by 10, it would be 10-m, but because it says 10 decreased by m, the answer is m-10

Answer:

20

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

One fifth of 45 = 45/5=9

This means 9 dogs require small bowls.

If 9 require small, 20 require medium and the rest require large, then 45-9-20=16

16 dogs need large size bowl.

Hope this helped!

Answer:

Domain: x ≥ 7

Range: y ≥ -1

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

Range is the set of y-values that can be outputted from function f(x).

We know that we can't take a square root of a negative and get a real number. The closest we can get is the square root of zero, no less.

What x-value renders the square root 0? x = 7 does, and we can't go less than that or we will get imaginary numbers. Therefore, the domain is x ≥ 7.

To find the range, we simply solve the rest of the function when x = 7, as we cannot go any lower.

y = 0 - 1

y = -1

Therefore, our range has to be y ≥ -1 because that would be the lowest y-value outputted from the lowest x-value.

Step-by-step explanation:

so you take the numbers and put them in order from least to greatest. so it would be negative -1, 0, 1, 1, 2, 3, 4, 9, 17, 25, 33, 41 .

Answer:

25

Step-by-step explanation:

Everytime, you add a value number 2 greater than the previous.

1+3=4

4+5=9

9+7=16

16+9=25

▹ Answer

25

▹ Step-by-Step Explanation

1 + 3 = 4

4 + 5 = 9

9 + 7 = 16

16 + 9 = 25

The pattern is increasing the value of which is added by two each time:

3 + 2 = 5

5 + 2 = 7

7 + 9 = 16

9 + 16 = 25

Step-by-step explanation:

three vectors are

[tex]u=(2,3,4)-(1,2,1)=(1,1,3)[/tex]

[tex]v=(3,4,5)-(1,2,1)=(2,2,4)[/tex]

[tex]w=(2,3,2)-(1,2,1)=(1,1,1)[/tex]

volume is given by [tex]V=u \cdot(v \times w)[/tex] [tex]v \times w=\left|\begin{array}{ccc}i & j & k \\ 2 & 2 & 4 \\ 1 & 1 & 1\end{array}\right|=(-2,2,0)[/tex]

so volume is [tex]V=(1,1,3) \cdot(-2,2,0)=0[/tex]

Complete question :

I received a letter from your competitor that mentions a savings of 15% over your prices. Can you match this offer? My current rate is $129.00 per month." Representative: "We will match any competitive offer. Your adjusted rate will be __________ dollars per month."

Answer:

$109.65

Step-by-step explanation:

Given the following :

Current rate = $129.00

Savings on current rate = 15%

Therefore, the adjusted rate will be 15% off the currently charged rate.

15% of $129.00

(15/ 100) × $129.00

0.15 × $129.00 = $19.35

Adjusted rate = current rate - adjustment

Adjusted rate = $129.00 - $19.35

Adjusted rate = $109.65

Hence, complete response :

We will match any competitive offer. Your adjusted rate will be $109.65 dollars per month."

Answer:

The value of limit = [tex]\frac{13}{8}[/tex]

Step-by-step explanation:

Explanation:-

Given  [tex]\lim_{x \to 4} \frac{x^{2}+5 x-36 }{x^{2}-16 }[/tex]

      =  [tex]\lim_{x \to 4} \frac{x^{2}+9 x-4 x-36 }{(x-4)(x+4) }[/tex]

     = [tex]\lim_{x \to 4} \frac{(x(x-4)+9(x-4) }{(x-4)(x+4) }[/tex]

     =[tex]\lim_{x \to 4} \frac{((x-4)(x+9)}{(x-4)(x+4) }[/tex]

   = [tex]\frac{4+9}{4+4}[/tex]

  = [tex]\frac{13}{8}[/tex]

Hence the limit exists and The value of limit = [tex]\frac{13}{8}[/tex]

Answer:

[tex]n = -5[/tex]

Step-by-step explanation:

Given

[tex]Digit = 0.000025[/tex]

Required

Rewrite using scientific notation, then find n

[tex]Digit = 0.000025[/tex]

Express as fraction

[tex]Digit =\frac{25}{1000000}[/tex]

This can be splitted to

[tex]Digit = 25 * 10^{-6}[/tex]

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

[tex]Digit = 2.5 * 10* 10^{-6}[/tex]

Apply law of indices

[tex]Digit = 2.5 * 10^{1-6}[/tex]

[tex]Digit = 2.5 * 10^{-5}[/tex]

Comparing n, the given options

[tex]n = -5[/tex]

Answer: Angle 1 is 129 degrees. Angle 2 is 51 degrees.

Answer:

see below

Step-by-step explanation:

The parallelogram on the left has an area of

A = bh

A = 7*4 = 28 ft^2

The rectangle on the right has an area of

A = bh

A = 8*15 = 120 cm^2

Step-by-step explanation:

For the parallelogram

Area of a parallelogram = b × h

where

b is the base

h is the height

From the question

b = 7 ft

h = 4 ft

So the area is

For the rectangle

Area of a rectangle = l × w

where

l is the length

w is the width

From the question

l = 15 cm

w = 8 cm

So the area is

Answer:

18.472 miles

Step-by-step explanation:

[tex]166.25 \: miles = 9 \: gallons \\ x \: miles = 1 \: gallons[/tex]

Cross Multiply

[tex]9x = 166.25[/tex]

Divide both sides of the equation by 9

[tex] \frac{9x}{9} = \frac{166.25}{9} [/tex]

[tex]x = 18.472[/tex]

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{18.472 \: miles}}}}}[/tex]

Step-by-step explanation:

Distance travelled = 166.25 miles

gallons of gas used = 9 gallons

To find : 1 gallons of gas = ? miles

In unitary method, we have to obtain unit quantity. So, to find the distance travelled using 1 gallons of gas, 166.25 is divided by 9

[tex] \sf{ \frac{166.25}{9} }[/tex]

[tex] \dashrightarrow{ \sf{18.472 \: miles}}[/tex]

Answer:

Length=17

width=13

Step-by-step explanation:

W=width

L=length

Perimeter = 2w+2l since it's a rectangle

W=l-4 (given)

Plug into perimeter equation

Perimeter =(2l-8)+2l

=4l-8

60=4l-8

68=4l

17 =l

W=l-4=17-4=13

Answer:

1050

Step-by-step explanation:

I'm pretty positive it would be 1050 by multiplying 50 and 20 and adding 50

The total number of seats in the auditorium are 2225.

Given is that an auditorium has 50 rows of seats. The first row has 20 seats, the second row has 21 seats, the third row has 22 seats.

We can write the sequence as -

20, 21, 22, 23, 24, .......,

It is a arithmetic sequence. We can write the total number of seats in the auditorium as the sum of the terms of the sequence. We can write -

S{n} = (50/2)(2 x 20 + 49 x 1)

S{n} = 25(40 + 49)

S{n} = 25 x 89

S{n} = 2225

Therefore, the total number of seats in the auditorium are 2225.

Answer:

Explained below.

Step-by-step explanation:

A graph is formed using the height of students in Diego's math class.

It is provided that he arranges the students from shortest to tallest and measures the height in inches of each student in the class.

A distribution is known as to be skewed to the right, or positively skewed, when maximum of the data are collected on the left of the distribution and the graph has a longer tail towards the right.

For a positively skewed data: Mean > Median

A distribution is said to be skewed to the left, or negatively skewed, if maximum of the data are collected on the right of the distribution and the graph has a longer tail towards the left.

For a negatively skewed data: Mean < Median

A distribution is said to be symmetric, if maximum of the data are collected in the middle of the distribution and the graph has equal proportion of tails on both sides.

For a symmetric data: Mean = Median

Answer:

65%

Step-by-step explanation:

The formula for the grade of the ramp = Rise of the ramp/ horizontal distance of the ramp

Rise of the ramp = 52 feet

Horizontal distance = 80 feet

Grade of the ramp = 52 feet/80 feet

= 0.65

The grade of the ramp is 0.65

Rounding up to the nearest whole percent

Grade of the ramp = 0.65 × 100

= 65%

Therefore, the grade of the ramp to the nearest whole percent = 65%
