Sophia had 64¢ until she spent 1 quarter. How much money does Sophia have now?

Answers

Answer:

Sophia now has 39 cents.

Step-by-step explanation:

One quarter = 25 cents

Since Sophia had 64 cents until she spent 25 cents (1 quarter).

So we subtract 25 cents from 64 cents.

[tex] \: \: \: 64 \: cents \\ \frac{ - 25 \: cents}{ \: \: \: 39 \: cents} [/tex]

Therefore, Sophia now has 39 cents.

If b=24 and c=10 what is for the missing side a= ? by Use the Pythagorean Theorem to find

Answers

Answer:

a = 21.82 if and only if b=10 and c=24

if you meant b=24 c=10

there can't be such a triangle because the hypotenuse is the longest side

Step-by-step explanation:

[tex]a^2+b^2=c^2\\\\a=?\\\\b=24\\\\c=10\\\\\\a^2+(24)^2=(10)^2\\\\a^2=(10)^2-(24)^2\\\\a^2=(10-24)(10+24)\\\\a^2=-14(34)[/tex]

which doesn't work because something squared can't be a negative

if you meant

c=24 and b=10

[tex]a^2+(10)^2=(24)^2\\\\a^2=(24)^2-(10)^2\\\\a^2=(24-10)(24+10)\\\\a^2=(14)(34)\\\\a\approx 21.82[/tex]

9514 1404 393

Answer:

  a = 26  or  21.82

Step-by-step explanation:

If 'a' is the hypotenuse, then ...

  a² = b² +c²

  a² = 24² +10² = 576 +100 = 676

  a = √676 = 26 . . . if 'a' is the hypotenuse

__

If 'a' is the long side, then ...

  b² = c² + a²

  b² -c² = a² = 24² -10² = 576 -100 = 476

  a = √476 ≈ 21.82 . . . if 'a' is the long leg

The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ Divide (3x² - 14x - 5) by (x - 5)

Now,

Divide (3x² - 14x - 5) by (x - 5) as;

x - 5 ) 3x² - 14x - 5 ( 3x + 1

        3x² - 15x

      -      +

      ------------------

               x - 5

              x - 5

           -      +  

         --------------------

                0

Thus, The solution after divide (3x² - 14x - 5) by (x - 5) will be (3x + 1).

A statue that is 80 m tall stands on a 625 m2 base. An artist creates a replica using a ratio of 1:15. What is the area of the replica's base?

Answers

Answer: [tex]2.78m^{2}[/tex]

Step-by-step explanation:

given data:

height of the statue = 80m.

base of the statue = [tex]625m^{2}[/tex].

scale of the statue replica = 1:15.

solution:

[tex]= 1:15^{2} \\\\\= 1:225\\\\[/tex]

[tex]= \frac{625m^{2} }{225}[/tex]

= [tex]2.78m^{2}[/tex]

What are the area and perimeter of square TUVW?
Area=
Perimeter=​

Answers

Answer:

Area: 196

Perimeter: 56

Step-by-step explanation:

1. Pick a side for both length and height and count the distance between the two coordinates (for example VU and UT)

VU = 14

UT= 14

Also important to note here that you don't even need to count the distance for both because since it's a square, all the sides are the same. Only did this to make it easier to understand the next step.

2. Since it's a square, as I said before, all sides are the same. So, you can go ahead and mark WT and VW as 14 as well.

3. To get the area, use the formula base times height.

14 x 14 = 196

4. For perimeter, simply add up all the sides (or multiply 14 by 4 since all are the same)

14+14+14+14=56

Step-by-step explanation:

First because it says "..2 out of 3" you have 2 boxes (i'm using a tape diagram) for the students that prefer gel toothpaste and 1 box for the others/don't prefer gel toothpaste students. Since there are 150 students in the school in total you will divide the number of students (150) by the 3 boxes and get 50. Each box will be filled with 50. Students that prefer gel toothpaste : 50 x 2 = 100 (students) Students that don't prefer gel toothpaste : 50 x 1 = 50 (students).

-6(8k+9c)-3 use c=2 and k=9

Answers

Answer:

-543

Step-by-step explanation:

For every value of k, you substitute 9 and for every value of c, you substitute 2

-6((8x(9)+ 9(2)) - 3

so order of operations says you should do what's in the parentheses first.

8 x 9= 72     and 9 x 2 = 18

so now you have -6 ( 72 + 18) -3

Finish the calculating inside the parentheses:   -6 (90) -3

and now multiply -6   and 90 before you subtract 3

-6 x 90 = -540

An architectural drawing lists the scale as 1/4" = 1'. If a bedroom measures 312" by 514" on the drawing, how large is the bedroom?

A. 7 ft by 10.5 ft
B. 14 ft by 21 ft
C. 20 ft by 30 ft
D. 10 ft by 15 ft

Answers

Answer:

1248' x 2056' so I think you missed copying decimals but I would asume B

Step-by-step explanation:

312''x(1/(1/4''))=1248'

514''x(1'/(1/4''))=2056'

The dimensions in feet's are 1248' x 2048'.

We have architectural drawing scale -  1' = 1/4"

We have to convert the dimensions 312" by 514" into feet's.

What does the symbol -  ' (prime) and '' (double prime) in measurement represents

double prime (″) is symbol for inches.

single prime (') is a symbol for foot(singular)/ feet's (plural)

1 foot =12 inches.

According to the question -

1' = 1/4"

1 foot = 1/4'' inches

Then, 1 inches will have = [tex]\frac{1}{\frac{1}{4} }[/tex] = 4 feet's.

Therefore -

312" = 312 x 4' = 1248 feet's

514" = 512 x 4' = 2048 feet's

Hence, the dimensions in feet's are 1248' x 2048'.

which equation represents a line that is perpendicular to line FG​

Answers

Note: You missed to add some basic information of the perpendicular line or missed the answer options, hence I am solving using a sample equation but it would clear your concept.

Answer:

Please check the attached graph.

Step-by-step explanation:

We know the slope-intercept form of line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Given the points

F(1, 8)G(-3, -4)

Finding the slope between F(1, 8) and G(-3, -4)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(1,\:8\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-4\right)[/tex]

[tex]m=\frac{-4-8}{-3-1}[/tex]

[tex]m=3[/tex]

Thus, the slope of the line FG = m = 3

From the given line, we can also determine the y-intercept 'b' by setting x = 0 and checking the corresponding y value.

i.e. at x = 0, y = 5

Thus, y-intercept b = 5

so substituting m = 3 and b = 5 in the slope-intercept form

y = mx+b

y = 3x+5

Therefore, the equation of line FG will be:

y = 3x+5

Please check the attached diagram, where the red line represents the line y=3x+5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Slope of Perpendicular line = -1/m = -1/3

Thus, any line with the slope m = -1/3 would be the line that will be perpendicular to line FG​

Let say the line with the slope m = -1/3 and y-intercept 2

y = -1/3x + 5

Please check the attached graph, the blue line is representing the perpendicular line y =  -1/3x + 5 to line FG

The graph of both lines is clearly representing that the line y = -1/3x + 5 is perpendicular to line FG.
