You have a jar filled with quarters and dimes. You choose 10 coins at random from the jar. Together, they are worth $2.05. How many of each type do you have?

Answer:

-m[tex]n^{2}[/tex]

Step-by-step explanation:

Answer: C

Step-by-step explanation: The answer is C because x is equivalent to 10 in both problems. X is equal to 10 in the problem 2x + 7 =27 because 2 x 10 = 20 + 7 = 27. X is also equal to 10 in the problem 5x - 15 = 35 because 5 x 10 = 50 - 15 = 35. This means the answer is C.

Answer:

54 feets

2.5 inches

Step-by-step explanation:

Given that:

Scale model:

5 in : 9ft

If 5 in = 9 ft

Hence, 1 in on the blue print equals

5 in = 9 ft

1 in = x

Cross multiply

5x = 9

x = 9/5 feets

Hence, 1 inches on the blueprint equals 9/5 feets actual

Blueprint length (in.) ___ Actual length (ft)

5 _________ 9

10 ________ 18

15 ________ 27

20 _______ 36

25 _______ 45

30 _______ 54

Hence ;

5 * 9/5 = 9 feets

10 * 9/5 = 18 feets

15 * 9/5 = 27 feets

20 * 9/5 = 36 feets

25 * 9/5 = 45 feets

30 * 9/5 = 54 feets

Window with actual width of 4.5 feets

Width of window in blue print :

Actual width ÷ 9/5

Actual width = 4.5 = 4 1/2 = 9/2

9/2 * 5 /9

= 5 /2

= 2 1/2 inches = 2.5 inches

The perimeter of the rectangle is 20 because 7x2+3x2=20

And 20/4(sides of a square) =5

Answer:

65

Step-by-step explanation:

the square means 90 add that to 25 and subtract from 180

Answer:

x =  65

Step-by-step explanation:

The measure of the entire angle is 180°. The angle on the furthest left (with a square in it) is a right angle, meaning that it is 90°.

All three of the angles (90°, x°, 25°) all add up to the measure of the line, which is 180°. So, we can write this equation.

90 + x + 25 = 180

Subtract 90 and 25 from both sides.

90 + x + 25 - 90 - 25 = 180 - 90 - 25

x =  65

Answer:

4

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

I think what you mean is y = 12, so I'll just go off that. So we substitute 12 for y and we get 4*12 + 6. Then we multiply. 48 + 6 and we get 54! I hope this helped and please mark brainliest!

y= kx

k= y/x

k= -3/4

make the constant K the subject

Answer:

[tex]V=20.85\ m^3[/tex]

Step-by-step explanation:

Given that,

The vessel is in the the form of a hemispherical bowl mounted by a hollow cylinder.

The diameter  of the sphere is 3.5 m.

The height of the cylinder is 2 m

Height of the cylinder = Height of bowl− Radius of hemisphere

= 2 - (3.5/2)

= 0.25 m

The volume of the vessel is given by :

V = volume of hemispherical bowl + volume of cylinder

So,

[tex]V=\dfrac{2}{3}\pi r^3+\pi r^2 h\\\\V=\dfrac{2}{3}\times \dfrac{22}{7}\times (\dfrac{3.5}{2})^3+\dfrac{22}{7}\times (3.5)^2\times 0.25\\\\V=20.85\ m^3[/tex]

So, the volume of the vessel is [tex]20.85\ m^3[/tex].

Answer:

I think 456.96

Step-by-step explanation:

Answer:

y = 1/3x + 2

Step-by-step explanation:

slope formula: (y₂ - y₁) / (x₂ - x₁)

(0, 2) & (3, 3)

Plug the values in.

(3 - 2) / (3 - 0)

Simplify the parentheses.

1/3

This fraction is fully simplified.

Your basic slope intercept form equation is: y = mx + b.

m is the slope, which is 1/3.

y = 1/3x + b

b is the y-intercept, which is y-value when x = 0.

From one of the points given, we can see that the y-intercept is 2.

Therefore, your equation is: y = 1/3x + 2

Check your answer with the other point.

3 = 1/3(3) + 2

3 = 1 + 2

3 = 3

Your equation is correct!

Hope this helps!

Answer:

7/23

Step-by-step explanation:

There seven black socks and all of the socks together is 23.

Answer:

1. AB= 8.94,

2. AB= 7.28

3. AB= 16.4

4. AB= 19.21

Step-by-step explanation:

This is fun! Well you have to find the (1,4) (or point e) point and count the distance to the other points point a and point b.

4 units from a to e and 8 b to e

a² + b² = c²

8² + 4² = c²

64 +16 = c

√80 = √c²

8.94 = c

It dose not matter which units you plug in for a and b but c has to be the long side of the triangle/ hypotonuse.

Follow the same steps for the rest of the problems.

On proplems 3 and 4 plot points first you can subtract the x-x and y-y as a short cut to find the units.

Answer:

1,172.3 cm³

Step-by-step explanation:

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod.  The volume of one rod is

V = (πd²/4)h

d = 4 cm

h = 20 cm

Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V.  If the result is not an integer, then round down.

Add

20 + 4 = 24

Then

28,134.4 ÷ 24 = 1172.26

Rounded to the nearest 0.1 or  the Tenths Place = 1,172.3

Therefore, 1,172.3 rods will be made per hour.

Answer:y = 7x + 5

Step-by-step explanation: does it matter which point it goes through?

Answer:

83 + g

Step-by-step explanation:

The total amount of peppers is calculated as:

Number of red peppers + Number of green peppers

Ruben has 83 red peppers and g green peppers.

The total amount of peppers =

83 + g

Therefore, the expression that models the situation =

83 + g

Answer:

the slope is −3 .

Answer:

2/3 (fact checking...)

Step-by-step explanation:

this is a problem constructed in Slope-Intercept form, the slope is the angle that the line plotted is at.

The intercept, aka the y-intercept is where the line crosses on the y axis, in this case since y is just y and not changed, the line crosses at 0 on the y coordinate.

The slope is 2/3 because when plotted, the line will cross the point on graph at the location (x,y) 2,3 as its nearest whole set of numbered coordinates to 0,0 along said line
