Answer:

Mark has 23 marbles, Don has 74 marbles

Step-by-step explanation:

Mark has x marbles, Don has y marbles

y = 5 + 3x

x + y = 97

so

x + (5 + 3x) = 97

4x = 97 - 5 = 92

x = 92/4 = 23

y = 97 - 23 = 74

Answer:

9680 yards

Step-by-step explanation:

There are 1760 yards in a mile. That times 5 is 8800. To get the full 5.5 just add half of what’s in a mile (880) and you get 9680 yards. :)

Money made after sale is:

The difference is 3 rupees:

Correct choice is B

Answer:

A

Step-by-step explanation:

look at the lines

A is going up and is linear

Answer:

1/1

Step-by-step explanation:

The reason why is because the spinner has 12 slices and on that spinner there is 12 yellow slices meaning all the slices on the spinner are yellow.

This means it is a 100% chance to land on yellow but 100% aas a fraction is 100/100.

You can simplify 100/100 a hundred times to 99/99 to 98/98 you can keep doing it but it's lowest form is the lowest number besides zero and that is 1 so it's lowest form is 1 out of 1 or 1/1 or 100%.

Hope this helps have a great afternoon:)

Answer:

y = -1

Step-by-step explanation:

5(2y−1)−2(2−y)+3(2y+9)=0

Step 1: Simplify both sides of the equation.

5(2y−1)−2(2−y)+3(2y+9)=0

(5)(2y)+(5)(−1)+(−2)(2)+(−2)(−y)+(3)(2y)+(3)(9)=0(Distribute)

10y+−5+−4+2y+6y+27=0

(10y+2y+6y)+(−5+−4+27)=0(Combine Like Terms)

18y+18=0

18y+18=0

Step 2: Subtract 18 from both sides.

18y+18−18=0−18

18y=−18

Step 3: Divide both sides by 18.

18y/18 = -18/18

Answer: y=−1

Answer:

As Per Given Information

Diameter of of baseball = 74 mm

We've been asked to find the volume of baseball .

As we know

Radius = Diameter/2

Radius = 74/2

Radius = 37 mm ( 1 mm = 0.1 cm)

Radius = 37/10 cm

Radius = 3.7 cm

Now let's calculate the volume of baseball

volume of baseball = 4/3 πr³

Put the given value we obtain

→ volume of baseball = 4/3 × 3.14 × (3.7)³

→ volume of baseball = 4/3 × 3.14 × 50.653

→ volume of baseball = 4/3 × 159.05042

→ volume of baseball = 636.20168/3

→ volume of baseball = 212.06

→ volume of baseball = 212 cm³ ( approx)

So, the volume of baseball is 212 cm³.

Solution:

We know that:

[tex]V_{Baseball} = \frac{4}{3} \pi r^{3} \\ \\ Diameter = 74 \space\ mm\\\\Radius = \frac{Diameter}{2}[/tex]

Finding the area of the baseball:

[tex]V_{Baseball} = (\frac{4}{3})( \pi )(r^{3})[/tex]

[tex]V_{Baseball} = [\frac{4}{3}][ 3.14 ][(\frac{74}{2}) ^{3}][/tex]

[tex]V_{Baseball} = [\frac{4}{3}][ 3.14 ][(37) ^{3}][/tex]

[tex]V_{Baseball} = [\frac{4}{3}][ 3.14 ][50653}][/tex]

[tex]V_{Baseball} = 212067.227 \space\ mm^{3} \space\ (Using\ calculator)[/tex]

Rounding the volume to the nearest tenth:

[tex]V_{Baseball} = 212067.227 \space\ mm^{3} = 212067.2 \space\ mm^{3}[/tex]

Thus, 212067.2 mm³ is the volume of the baseball.

Answer:

its not showing up on the screen

Answer:

Here's one way to do it.

Explanation:

Let

f

(

x

)

=

x

3

−

2

x

2

+

3

x

.

(Needed because the intermediate value theorem is a theorem about functions .)

Observe that the equation

x

−

2

x

2

+

3

x

=

5

has a root (a solution) exactly when

f

(

x

)

=

5

So the question now is to show that for at least one number

c

, in

[

1

,

2

]

, we get

f

(

c

)

=

5

.

f

is continuous on

[

1

,

2

]

(Because it is a polynomial and they are continuous everywhere.)

f

(

1

)

=

2

and

f

(

2

)

=

6

5

is between

f

(

1

)

and

f

(

2

)

, so

by the intermediate value theorem, there is at least one number

c

, in

[

1

,

2

]

, for which

f

(

c

)

=

5

.

That is, the original equation has a solution.

Answer:

Step-by-step explanation:

Opposite angles of a rhombus are congruent, so [tex]6x+8=86 \longrightarrow x=13[/tex]

Also, adjacent angles of a rhombus are supplementary, so [tex]86+5z+4=86+7y+3=180 \longrightarrow y=13, z=18[/tex]

Answer:

Step-by-step explanation:

3x + 6 + 4x + 20 = 180

7x + 26 = 180

7x = 154

x = 22

m<A= 3(22) + 6 = 66 + 6 = 72°

m<B = 4(22) + 20 = 88 + 20 = 108°

Answer:

2 ⅓  

Step-by-step explanation:
