Susan's penny bank is 1/10 full. After she adds 240 pennies, it is 2/5 full. How many pennies can Susan's bank hold?

Answer:

m<Q = 92 degrees

Step-by-step explanation:

Opposite angles of a quadrilateral inscribed in a circle are supplementary.

Angles O and Q are opposite angles, so they are supplementary, so their measures add up to 180 degrees.

m<O + m<Q = 180

2x + 2x + 4 = 180

4x + 4 = 180

4x = 176

x = 44

m<Q = 2x + 4 = 2(44) + 4 = 92

Answer:

Q =92

Step-by-step explanation:

Since the quadrilateral is inscribed in a circle, the opposite angles add to 180 degrees.

<O + <Q = 180

2x+ 2x+4 = 180

4x+4 =180

Subtract 4 from each side

4x= 180-4

4x= 176

Divide by 4

x = 44

Q = 2x+4

Q = 2(44)+4

Q = 88+4

Q = 92

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-7, 2) and (9, 6). Substitute:

[tex]m=\dfrac{6-2}{9-(-7)}=\dfrac{4}{16}=\dfrac{1}{4}[/tex]

The slope of the line passing through the points (-7,2) and (9,6) is 1/4.

Point-slope formula

[tex]y-y_{1} = m(x-x_{1} )[/tex]

In the slope formula, m stands for slope which is calculated as the

[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$$[/tex]

= Δy/Δx

where, m = slope

[tex](x_1, y_1)=[/tex] coordinates of the first point in the line

[tex](x_2, y_2)=[/tex] coordinates of the second point in the line

We have the points (-7,2) and (9,6).

Substitute the values [tex]x_{1}}$$[/tex], [tex]{x_{2}[/tex] and [tex]y_{1}}[/tex], [tex]${y_{2}[/tex]  in the above equation, we get

[tex]$m=\frac{6-2}{9-(-7)}[/tex]

[tex]$=\frac{4}{16}=\frac{1}{4}$[/tex]

Therefore, the slope m = 1 / 4.

Answer: x = 6

==============================================

Explanation:

The medians of a triangle meet up at the centroid in such a way that they cut each other at a ratio of 2:1, meaning that one part of the median is twice as long as the other. In this case, MO is two times longer than OP, so,

OP = 2*MO

and

MP = MO + OP

MP = MO + 2*MO .... replace OP with 2*MO

MP = 3*MO

9x-24 = 3*(x+4) ... plug in the given expressions

9x-24 = 3x+12

9x-3x = 12+24

6x = 36

x = 36/6

x = 6

Answer:

Option C is correct.

The answer for the given expression is 0.

Step-by-step explanation:

Given the statement: Two times the difference of one-third of a number and three. and also variable given is 9.

Let x be the variable or number.

"One-third of a number"  means [tex]\frac{1}{3}x[/tex]

Also, "difference of one third of a number and three " means [tex]\frac{1}{3}x-3[/tex]

Now, "Two times the difference of one-third of a number and three" means   [tex]2 \times (\frac{1}{3} x -3)[/tex]

Then, the expression for the given statement : [tex]2 \times (\frac{1}{3} x -3)[/tex]

Substitute the value of x =9 in above expression we have;

[tex]2 \times (\frac{1}{3}(9) -3)[/tex] = [tex]2 \times (3 -3)[/tex] = [tex]2 \times (0)[/tex] = 0

therefore, the answer for the given expression is, 0

Answer:

x   = 5 sqrt(6)/3

 y= 10 sqrt(6)/3

Step-by-step explanation:

We know sin 60 = opposite/hypotenuse

    sin 60 = 5 sqrt(2) /y

 Multiply each side by y

y sin 60 = 5 sqrt(2)

Divide each side by sin 60

y sin 60/ sin 60 = 5 sqrt(2)/ sin 60

y = 5 sqrt(2) / sin 60

y = 5 sqrt(2) / sqrt(3) /2)

y   = 10 sqrt(2)/ sqrt(3)

You cannot leave a sqrt in the denominator

 y=   10 sqrt(2)/ sqrt(3) * sqrt(3)/sqrt(3)

   y= 10 sqrt(6)/3

tan 60 = oppositve/ adjacent

tan 60 = 5 sqrt(2)/ x

Multiply each side by x

x tan 60 = 5 sqrt(2)

Divide by tan 60

x = 5 sqrt(2)/tan 60

x =5 sqrt(2)/sqrt(3)

You cannot leave a sqrt in the denominator

x = 5 sqrt(2)/sqrt(3) * sqrt(3)/sqrt(3)

x   = 5 sqrt(6)/3

Exterior angles of triangles = 360°.

So by definition:

[tex]9x + 6 + 10x - 1 + 10x + 7 = 360\\29x + 12 = 360\\29x = 348\\x = 12[/tex]

The value of x is 12.

Answer: 12

Step-by-step explanation:

We know that the sum exterior angles of a polygons is [tex]360^{\circ}[/tex].

Therefore,according to the given picture , we have

[tex]\angle{GHJ}+\angle{HJG}+\angle{JGH}=360^{\circ}\\\\\Rightarrow\ (9x+6)^{\circ}+(10x-1)^{\circ}+(10x+7)^{\circ}=360\\\\\Rightarrow\ 9x+6+10x-1+10x+7=360\\\\\Rightarrow\ 29x+12=360\\\\\Rightarrow\ 29x=348\\\\\Rightarrow\ x=\dfrac{348}{29}\\\\\Rightarrow\ x =12[/tex]

Hence, the value of x = 12

Answer: [tex]\bold{\dfrac{8}{13}}[/tex]

Step-by-step explanation:

Red   or    Face   -  duplicates (both red & face)

[tex]\dfrac{26}{52}[/tex]     +       [tex]\dfrac{12}{52}[/tex]      -     [tex]\dfrac{6}{52}[/tex]

= [tex]\dfrac{32}{52}[/tex]

= [tex]\dfrac{8}{13}[/tex]   simplified

Final answer:

The probability of selecting a red or face card from a standard deck of cards is 8/13. This outcome is more likely than selecting a heart suit face card specifically, which has a probability of 3/52.

Explanation:

The problem can be solved by understanding that the deck has 26 red cards (hearts and diamonds) and 12 face cards (jacks, queens, and kings), with 6 face cards being red. The total number of unique choices that are either red cards or face cards is the number of red cards plus the number of black face cards. This avoids double-counting red face cards.

There are 26 red cards, but we need to exclude the 6 red face cards already counted, and add the 6 black face cards (from clubs and spades), giving us 26 + 6 = 32 unique cards that are either red or face cards. The probability, P, is then 32/52, which simplifies to 8/13.

To compare, the probability of drawing specifically a heart suit face card is 3/52 as there are only 3 face cards (jack, queen, and king) in the heart suit. Comparing probabilities, 8/13 is greater than 3/52, so it is more likely to draw a red or face card than a heart suit face card.

A grandfather = 2

Two mothers = 1 and 3

Two fathers = 2 and 4

i.e. Up until here there are total 4 people - Grandmother, Grandfather, Mother, Father ( 1, 2, 3, 4)

Four children = 4, 6, 7, 8

Three grandchildren = 6, 7, 8

Answer:

53 minutes.  

Step-by-step explanation:

We have been given that Payton leaves  to go on an 85 minute bike ride at 3:27 pm.

Let us find when Payton will finish biking by 85 minutes after 3:27 pm.

Since 85 minutes equals to 1 hour and 25 minutes. 1 hour after 3:27 pm will be 4:27 pm. Now let us add 25 minutes to 4:27 pm.

So Payton will finish biking at 4:(27+25) pm= 4:52 pm.

Payton's family eats dinner at 5:45 pm. Now let us find remaining time between dinner and 4:52 pm.

[tex]\text{Minutes between dinner and finishing bike ride}=5:45 pm- 4:52 pm[/tex]  

[tex]\text{Minutes between dinner and finishing bike ride}=53[/tex]  

Therefore, Payton have 53 minutes between finishing her bike ride and eating dinner.

Answer:

34 miles is the distance from point A will they meet.

Step-by-step explanation:

Proportion states that the two ratios or fractions are equal.

Given the statement:

Distance between point A and B (i.e AB) = 200 mi.

Let the cyclist speed be c, and motor- speed be m;

then;

c = 17 mph and m=83 mph

Let they meet at distance x miles from a point A.  

By definition of proportion, we have;

[tex]\frac{x}{17} =\frac{200-x}{83}[/tex]

By cross multiply;

[tex]83x = 17(200-x)[/tex]

Using distributive property, [tex]a\cdot(b+c) =a\cdot b+ a\cdot c[/tex]

[tex]83x = 3400 - 17x[/tex]

Add 17x both sides we get;

[tex]83x+ 17x= 3400 - 17x +17x[/tex]

Simplify:

100x = 3400

Divide by 100 on both sides we get;

x = 34 miles

Therefore, the distance from point A will they meet is, 34 miles.

Answer:  Since 1/3 can't be turned into a decimal, change .5 into 1/2. In order to subtract, the fractions need a common denominator. The least common denominator is 6. So 1/3 turns into 2/6, and 1/2 turns into 3/6. Now you need to take 9 3/6 minus 6 2/6. The answer is 3 1/6 gallons of water.

Step-by-step explanation:

Final answer:

To find the remaining water in Tank A after pouring out 6 1/3 gallons, subtract 6.333 from the tank's total capacity of 9.5 gallons, which leaves 3.167 gallons remaining in the tank.

Explanation:

The question involves determining the remaining quantity of water in a tank after a certain volume has been removed, which is a basic subtraction problem in mathematics. To solve it, subtract the volume of water that was poured out from the total capacity of the tank.

Tank A capacity: 9.5 gallons

Volume of water poured out: 6 1/3 gallons

To perform the subtraction, we first need to convert 1/3 of a gallon into a decimal. A third of a gallon is approximately 0.333 gallons. Adding this to 6 gallons gives us 6.333 gallons.

Now, subtract the volume poured out from the tank's capacity:

9.5 gallons (capacity) - 6.333 gallons (poured out) = 3.167 gallons (remaining in the tank)

Therefore, 3.167 gallons of water are left in the tank.
