Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 5 more than 3 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 97? Mark has Number marbles to sell. Don has Number marbles to sell.
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

Make a number line and mark the points that represent the following values of x.
x squared=16
Please mark where this is suppose to go on the number line :)
Answer:
Positive 4
Step-by-step explanation:
4 squared is equal to 16 as 4 x 4 = 16. However, if it was -4 squared, it would equal -16.
f(x)=x^3- X-1; between 1 and 2
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.

If
f(x) = ax + b,
where a, and b are constants, what is f(b)?
Select the correct answer below:
O f(b) = 2ab
O f(b) = ab + b
O f(b) = a + b
O f(b) = ab + a
< Previous
Answer:
f(b) = ab+ b
Step-by-step explanation:
Given f(x) = ax + b
To find f(b) plug b in for x.
f(b) = ab + b

A baseball measures approximately 74 mm in diameter. What is the volume of a baseball? (Round your answer to the nearest tenth if needed)
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.
Find the value of x, y, and z in the rhombus below.
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]
SOLVE 5( 2y-1)-2(2-y)+3(2y+9)=0
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

At the school's fall bake sale, all of the pies were cut into 6 pieces, so each person who bought a piece bought 1/6 of a pie. Each slice of pie sold for $1.00. How much money did the school make if all eleven pies were sold? (In other words, find 11 divided by 1/6 .)
Answer: $66.00
Step-by-step explanation: If every 1/6 is 1 dollar then that means a whole pie is 6 dollars
6 * 11 = 66

∠A and ∠B are supplementary. m∠A = (3x + 6), m∠B = (4x + 20). Find the measure of each angle.
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°

A person bought some articles at the rate of 5 per rupee (₹) and the same number of articles at the rate of 4 per rupee (₹). He mixed both the types and sold them at the rate of 9 for ₹2. In this business, he suffered a loss of ₹3. The total number of articles bought by him was:
a. 1090
b. 1080
c. 540
d. 545
Answer:
B. 1080Step-by-step explanation:
Lets assume the number of articles was x.
Half of the articles was bought at the price 1/5 rupee each and the other half was bought at the price 1/4 rupee each.
Cost of articles:
1/2x*1/5 + 1/2x*1/4 = 1/2x(1/5 + 1/4) = 1/2x(4/20 + 5/20) = 9/40xMoney made after sale is:
2/9x according to rateThe difference is 3 rupees:
9/40x - 2/9x = 381/360x - 80/360x = 31/360x = 3x = 3*360x = 1080Correct choice is B
A spinner with 12 equally sized slices has 12 yellow slices. The dial is spun and stops on a slice at random. What is the
probability that the dial stops on a yellow slice?
Write your answer as a fraction in simplest form.
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:)
