The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%
90% = 18
And we have to add 4 more because 10%×2.
So the total comes to 18+4= 22.
If student A is 160 cm tall, and the student B is 20% shorter than student A, what is the height of student B?
Answer:
128
Step-by-step explanation:
It’s actually quite simple all you have to do is find out what 20% of 160 is then subtract the 20% by 160 to get your final answer UwU

Answer:
[tex]-\frac{7}{8}a-\frac{1}{6}[/tex] (the first box is 7/8 and the second box is 1/6)

Step-by-step explanation:
A sloth crawled 6 cm in one second. What was its speed in km/h? (1 hr =
3600 s) (1 km = 100,000 cm)
Step-by-step explanation:
it was measured that the south crawled 6cm in 1 second.
that gets expressed by the ratio
6 cm/sec or formally correct 6/1 cm/sec.
to get that speed in km/h (kilometers per hour), we need to transform the denominator of that ratio to 1 hour.
the only way we can manipulate a fraction or ratio without changing its value is by multiplying numerator and denominator (top and bottom) by the same factor.
like x/y × 3/3 = 3x/3y.
the driver behind a question of this kind is again the denominator. we want the denominator to appear as 1 hour.
so, what do I need to multiply 1 second with to get 1 hour ?
the problem definition tells us : 3600, as there are 3600 seconds in 1 hour.
so, we need to multiply
6/1 × 3600/3600 = (6×3600)/3600 = 21600/3600 =
21600cm/1 hour.
and now, how many km are 21600 cm ?
1 km = 100000 cm
so,
21600cm = 21600/100000 km = 0.216 km
therefore, or full answer is
the sloth's speed was 0.216 km/h

Answer:
{x | 0 < x ≤ 5}
Step-by-step explanation:
The domain of a function describes all the values x could taken on in order to produce an output. You can notice the value of x is farthest left at a value of 0, which has an open dot and the value of x that is farthest right is at 5 with a closed dot. A closed dot includes the value while an open does not. This means x can be equal to 5, but not zero. We can write our domain as follows:
{x | 0 < x ≤ 5}

A shipping container is in the shape of a right rectangular prism with a length
of 13.5 feet, a width of 11 feet, and a height of 5-5 feet. The container is
completely filled with contents that weigh, on average, 0.93 pound per cubic
foot. What is the weight of the contents in the container, to the nearest
pound?
Answer:760 lbs
Step-by-step explanation:
The volume of a right rectanglar prism (i.e., a box) is length*width*height.
Volume = (13.5)*(11)*(5.5) = 817 ft^3
Density = 0.93 lb/ft^3
Weight of container contents = (817 ft^3)*(0.93 lg/ft^3) = 760 lbs

Simone applied the distributive property using the greatest common factor to determine the expression that is equivalent to 24 + 56. Her work is shown below.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
24 + 56 = 8 (4 + 7)

Answer:P2,700,000
Step-by-step explanation:
P100,000 must be added to the purchase price every year from 2009 to 2021. A formula calculating the value, V, as a function of time, t, where t is years since 2009, would be:
V(t) = P1,500,000 + (t - 2009)*(100,000)
V(2021) = P1,500,000 + (2021 - 2009)*(100,000)
V(2021) = P2,700,000

There are 3 teaspoons in 1 tablespoon. How many teaspoons are there in 6 tablespoons?
Answer:
18
Step-by-step explanation:
we can solve this as a ratio, from teaspoons to tablespoon is 3:1. if the tablespoon is 6 then the ratio becomes ?:6. Since we multiplied 1 by 6 we have to multiply 3 by 6 making the ratio 18:6.

Step-by-step explanation:

The value of the missing side of the triangle is 24.
What is the similarity?Similarity refers to the degree of resemblance or likeness between two or more things, concepts, or ideas. It can be measured in various ways, depending on the context and the characteristics being compared.
Scale factor refers to the ratio of the size of an object in the original form to its size in the scaled or transformed form. It is commonly used in geometry and mathematics to describe how the dimensions of an object have changed after a transformation such as scaling, stretching, or shrinking.
From the given figure the value of the missing number is calculated as,
36 / 24 = x / 16
x = ( 8 x 3 )
x = 24
Therefore, the value of an unknown number is x = 24.

Given series is
[tex]\rm \longmapsto\:\displaystyle\sum_{k=1}^{\infty}\rm \displaystyle\sum_{n=1}^{\infty}\rm \frac{k}{ {2}^{n + k} } [/tex]
can be further rewritten as
[tex]\rm \: = \: \:\displaystyle\sum_{k=1}^{\infty}\rm \displaystyle\sum_{n=1}^{\infty}\rm \frac{k}{ {2}^{k} . {2}^{n} } [/tex]
can be further rewritten as
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \bigg[\dfrac{k}{ {2}^{k}}\displaystyle\sum_{n=1}^{\infty}\rm \dfrac{1}{ {2}^{n} } \bigg][/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \dfrac{k}{ {2}^{k} }\bigg(\dfrac{1}{2} + \dfrac{1}{ {2}^{2} } + \dfrac{1}{ {2}^{3} } - - - \infty \bigg) [/tex]
So, its an infinite GP series with
[tex] \purple{\rm \longmapsto\:a = \dfrac{1}{2}}[/tex]
[tex] \purple{\rm \longmapsto\:r = \dfrac{1}{2}}[/tex]
We know,
Sum of infinite GP series with common ratio r ( - 1 < r < 1 ) and first term a is given by
[tex]\boxed{\tt{ \: \: S_ \infty = \frac{a}{1 - r} , \: \: provided \: that \: |r| < 1}}[/tex]
So, 1using this, we get
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{1 - \frac{1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{ \frac{2 - 1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }\bigg( \frac{ \frac{1}{2} }{ \frac{1}{2} }\bigg)[/tex]
[tex]\rm \: = \: \displaystyle\sum_{k=1}^{\infty}\rm \frac{k}{ {2}^{k} }[/tex]
[tex]\rm \: = \: \dfrac{1}{2} + \dfrac{2}{ {2}^{2} } + \dfrac{3}{ {2}^{3} } + \dfrac{4}{ {2}^{4} } + - - - \infty [/tex]
Let assume that
[tex]\rm \longmapsto\:S_ \infty = \: \dfrac{1}{2} + \dfrac{2}{ {2}^{2} } + \dfrac{3}{ {2}^{3} } + \dfrac{4}{ {2}^{4} } + - - - \infty [/tex]
Now, its an infinite Arithmetico Geometrico Series, So multiply by 1/2 we get

On Subtracting above two equations, we get
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{1}{2} + \dfrac{1}{ {2}^{2} } + \dfrac{1}{ {2}^{3} } + \dfrac{1}{ {2}^{4} } + - - - \infty [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{ \dfrac{1}{2} }{1 - \dfrac{1}{2} } [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: \dfrac{ \dfrac{1}{2} }{ \dfrac{1}{2} } [/tex]
[tex]\rm \longmapsto\:\dfrac{1}{2} S_ \infty = \: 1[/tex]

Hence,

Multiply Both sides by 20, Which is the LCM of 5, 4:
[tex]\mapsto \sf (4\times 5+2)=20x-5(4+1)[/tex]
Multiply 4 and 5= 20, and add 20 +2 =22
[tex]\mapsto \sf -4\times 22=20x-5(4+1)[/tex]
Multiply -4 * 22 = -88, and then add 4+1=5:
[tex]\mapsto \sf -88=20x-5\times 5[/tex]
Multiply -5 *5 = -25:
[tex]\mapsto \sf -88=20x-25[/tex]
Now, swap sides:
[tex]\mapsto \sf 20x-25=-88[/tex]
Add 25 to both sides:
[tex]\mapsto \sf 20x=-88+25[/tex]
[tex]\mapsto \sf 20x=-63[/tex]
Divide both sides by 20:
[tex]\mapsto \sf x=\cfrac{-63}{20}[/tex]
Now, convert an improper fraction to a mixed number: →
[tex]\mapsto \sf x= -3\cfrac{3}{20}[/tex]
