Step-by-step explanation:

To find - What is the equation that corresponds to the following expression ? : The half of the sum of 4.5 and another number is equal 13.5

Solution -

Let the another number be x

Given that ,Half of the sum of 4.5 and x  is equals to 13.5

So,

The expression becomes

Answer:

(110,90)

Step-by-step explanation:

The values are expressed as (age in months, weight in kilograms) so since the panda is 110 months old and 90 kilograms, so the values would translate into (110,90)

Hope this helped!

Answer:

4x+30

Step-by-step explanation:

Age of Adam=x Age of Beth= x+10 Age of Collin= 2(x+10)

Add like terms

x+(x+10)+2(x+10)= x+x+10+2x+20= 4x+30

Answer:

9/4 or 2 1/4 cups of sugar.

Step-by-step explanation:

To find the answer we multiply 3/4 by 3.  Because the bottom stays the same, we wont multiply it.  Since 3 x 3 = 9, it will be 9/4.  Therefore, 9/4 or 2 1/4 is your answer.

Answer:

y = 6[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

cos45° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{y}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

y = 6[tex]\sqrt{2}[/tex]

The ~ mark means "similar"

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

The red angle markings tell us which angles are congruent to one another. We have these two pairs of congruent angles

Because we have two pairs of congruent angles, we use the AA similarity theorem. AA stands for angle angle. We could use three pairs, but two pairs is the minimum needed for similarity statements.

-----------

To figure out what goes in the third answer box, note how the order HGF is given to us. The order is important.

We have H first, G second, F third.

H being first, and it having a single arc, means that whatever has a single arc on the other triangle must be first. That would be H. Unfortunately they reuse angle H which makes things confusing a bit.

G is second in HGF, and G has the double arc marking. Note how M also has this double arc marking. Therefore we have M second in the answer. So far we have HM as part of the third answer.

The only thing left is N. Therefore, we have triangle HMN as the answer for the third box.

Put another way, we have these pairings:

This is why the order is important. So we can see how the angles pair up in the order that they do.

This is why triangle HGF is similar to triangle HMN.

We can write that as triangle HGF ~ triangle HMN

The ~ mark means "similar"

We don't have enough information to prove that the triangles are congruent or not. So we cannot say [tex]\triangle HGF \cong \triangle HMN[/tex]. Your teacher made a typo when using the congruence symbol [tex]\cong[/tex]

Instead, it should be [tex]\triangle HGF \sim \triangle HMN[/tex]

Answer:

add equation 2 from equation 3

Step-by-step explanation:

So, we are given equations 1, 2, and 3, but for this problem, we need to use just 2 and 3.

4x - 2y = -16

x + 2y = 6

In order to eliminate one variable, then we need to find whether there are two numbers that have the same coefficient (or multiply one by a number to make it) so that if you add/subtract two numbers, it gives you 0. So, in this problem, if you add

2y to -2y, then it gives you 0, which means that y would be canceled out.

So, the answer is the first option.

Feel free to ask any questions about clarity! (this explanation is pretty bad, but  I can explain it more if you want) :D

Answer:

[tex] \frac{7}{25} [/tex]

Step-by-step explanation:

We can solve that using this identity,

[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]

plug in -24/25 from x in sin

[tex] \sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \cos {}^{2} (x) = 1 - \frac{576}{625} [/tex]

[tex] \cos {}^{2} (x) = \frac{49}{625} [/tex]

[tex] \cos(x) = \frac{7}{25} [/tex]

Since cos is positve in quadrant 4, the answer is 7/25.

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

then

Sin(Ф) = - [tex]\frac{24}{25}[/tex]

find the angle Ф

Ф = arcSin ( - [tex]\frac{24}{25}[/tex] )

Ф = -73.739795°

so an angle measured clock wise from x axis at zero°

now use cos(Ф) = x/ 25    to find x

25* cos(  -73.739795°) = x

7 = x   :o  wow... exactly?   :P nice

cos(Ф) = 7/25     I think that's what they wanted to know  

also I noted my calculator tried to find the fraction of 0.2800000049 and couldn't,  but then I just put in 0.28 and it found that to be 7/25  :0  so I think we're spot on  :)  

Answer:

90 males.

Step-by-step explanation:

To find the answer we will divide 45% by 100, and we get 0.45.  Now multiply 0.45 by 200 and you get 90.  Therefore, 90 males is the answer.

Answer:

7x^3y^2 + 14x^2y^3 - 35x^2y^2

Step-by-step explanation:

Answer:

x= -17/8

Step-by-step explanation:

1 step: take care of the parentheses ( multiply -2 to what is on parentheses)

so x -8x +6 =-12-14x

2 step : move all number with x to the left side

x-8x +14x = -12 -6

7x = -18

x = -18/7

Answer:3/3 would be your slope

Step-by-step explanation:

Answer:

[tex](x-2)^2+(y-5)^2=9^2[/tex]

Step-by-step explanation:

We use the equation

[tex](x-h)^2+(y-k)^2=r^2[/tex]

Now we plug in the numbers

(h, k) = center point (2, 5)

This would equal

[tex](x-2)^2+(y-5)^2=9^2[/tex]

Answer:

slope: 10

Step-by-step explanation:

equation: y = 10x + 15

slope = 10

y-intercept = 15

slope is 10 because it's 10 dollars for every hour

y-int is 15 because he had an additional fee of 15 dollars

All the correct expressions that could be used to find the volume of the hamster house are,

⇒ (1 × 3 × 4) + (6 × 3 × 2)

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

One rectangular prism has a length of 1 foot, width of 3 feet and height of 4 feet.

And, The second rectangular prism has a length as 6 feet, width as 3 feet and height as 2 feet.

Hence, Volume of first rectangular prism is,

⇒ 1 × 3 × 4

And,  Volume of second rectangular prism is,

⇒ 6 × 3 × 2

Thus, All the correct expressions that could be used to find the volume of the hamster house are,
