Mrs. Garcia owns a day-care. She brought 8 toy truck's 6toy cars 4 toy boats 6 toy planes is she combines the transportation toys and places an eaual number into 3 containers, how many will be in each container?

Answer:

Because s and t are parallel x=12

Step-by-step explanation:

To get this you have to solve for (4x-12)+120=180 solve for x

4x+12=60

4x=48

=12

The equation is written as 4x - 12 + 120 = 180. Then the value of the variable 'x' will be 18. Then the correct option is A.

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The sum of the angle (4x - 12)° and (120)° will be equal to 180°. Then the equation is given as,

4x - 12 + 120 = 180

Simplify the equation, then we have

4x - 12 + 120 = 180

4x = 72

x = 72 / 4

x = 18

The equation is written as 4x - 12 + 120 = 180. Then the value of the variable 'x' will be 18. Then the correct option is A.

ANSWER

[tex]S_4 = \frac{208}{375} [/tex]

EXPLANATION

The given series is:

[tex]\sum_{n=1}^{\infty} \frac{2}{3} ( - { \frac{1}{5} })^{n - 1} [/tex]

When n=1, the first term is

[tex]a = \frac{2}{3} [/tex]

The sum of terms of a geometric sequence is given by the formula;

[tex]S_n = \frac{a {(1 - {r}^{n} )} }{1 - r} [/tex]

The sum of the first 4 terms is:

[tex]S_4= \frac{ \frac{2}{3} {(1 - { ( - \frac{1}{5} )}^{4} )} }{1 - - \frac{1}{5} } [/tex]

[tex]S_4 = \frac{208}{375} [/tex]

The value for S4 is represented by the third option, [tex]\frac{208}{375}[/tex] .

You can define a geometric sequence when you have a common ratio between the numbers of a sequence. This common ratio can be found when you multiply or divide the previous term by the next term of the sequence and you find the same value. The formula for geometric sequences is:

[tex]a_n=a_1*r^{n-1}[/tex], where:

[tex]a_n[/tex]=[tex]n^{th}[/tex] term

[tex]a_1[/tex]= the first term

Example

2, 4,8, 16, ....

Here, you have:

[tex]a_1[/tex]= 2

[tex]r=\frac{a_2}{a_1}=\frac{a_3}{a_2}=2[/tex] ,  then: 2 x 2= 4; 4 x 2=8; 8 x 2=16 - Note that the numbers represent the example sequence.

For solving this exercise also it is necessary to apply the formula for the geometric sequence for finite terms since the question asks [tex]S_4[/tex], in the other words, the sum for n=4. Thus,[tex]S_n=\frac{a_1*(1-r^n)}{1-r}[/tex].

For the given series, when n=4, you have

                              [tex]\frac{2}{3} *(\frac{-1}{5})^{n-4} \\ \\ \frac{2}{3} *(\frac{-1}{5})^{4-4}\\ \\ \frac{2}{3} *(\frac{-1}{5})^{0}\\ \\ \frac{2}{3} *1=\frac{2}{3}[/tex]

Therefore, [tex]a_1=\frac{2}{3}[/tex].

Now, you will find S4 from the formula for the geometric sequence for finite terms

[tex]S_n=\frac{a_1*(1-r^n)}{1-r}\\ \\ =\frac{\frac{2}{3}\cdot \left(1-\left(-\frac{1}{5}\right)^4\right)}{1-\left(-\frac{1}{5}\right)}\\ \\ \frac{\frac{2}{3}\left(1-\left(-\frac{1}{5}\right)^4\right)}{1+\frac{1}{5}}=\frac{\frac{416}{625}}{\frac{6}{5}}=\frac{416\cdot \:5}{625\cdot \:6}=\frac{208}{375}[/tex]

Answer:

Using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8

Step-by-step explanation:

You use a bar graph to compare things between different groups, so it is the most appropriate one to use.

You use a pie chart to compare parts of a whole, so it would not be appropriate.

The graph should represent the relative sizes of the two values (24:18 or 1.33:1). Using a square or a cube would distort the relationship. The relative area of the squares would be 1.77:1 and that of the cubes would be 2.37:1.

Charts are used to represent data graphically.

The best way to represent the data is (a) using a bar graph where one bar has a length of 2.4 and one bar has a length of 1.8

The given parameters are:

[tex]\mathbf{Student = 2.4}[/tex]

[tex]\mathbf{Graduate = 1.8}[/tex]

Both data elements, are for different people.

So, it is best to use a bar chart.

Using a pie chart will imply that, the data elements are part of a whole data for a particular person.

Squares and cubes cannot be used at all.

Hence, the correct option is (a).

Check the picture below.

now, let's recall that running a segment from a midpoint across to a midpoint in a triangle, creates a midsegment, and a midsegment which is parallel to the "base" of the triangle, is always half of that base.

now, noticing the picture on the top-left triangle, we know those points are midpoints, so those in red are midsegments and therefore half the base, to make it short

IC = HE/2 = 7

JB = IC/2 = 3.5

CH = 2DG = 8

likewise, on the green triangle ACH, the midsegment IB is half of the base CH, we know CH = 8, so IB = 4.

Answer:

The equation of the perpendicular line is y = -x - 2

Step-by-step explanation:

* Lets revise the form of the slope intercept for

- The slope intercept form is y = mx + b, where m is the slope of

  the line and b is the y-intercept

* Now lets revise the relation between the slopes of the

 perpendicular lines

- If two lines are perpendicular, then the product of their slopes is -1

# Ex: If line L has slope m1 and line K has slope m2, and L ⊥ K

∴ m1 × m2 = -1

∴ m2 = -1/m1

* Now lets solve the problem

- We need to find the equation of the line which is perpendicular to

 the line whose equation is y = x + 3 and passes through point (2 , -4)

- Find the slope of the given equation

∵ y = x + 3

- In this form the slope is the coefficient of x

∴ m = 1

- Find the slope of the perpendicular line

∵ The slope of the perpendicular line = -1/m

∴ The slope of it = -1/1 = -1

- Write the equation of the line with the value of the slope

∴ y = -x + b

- To find the value of b substitute x , y in the equation by the x and

  y of the given point

∵ The line passes through point (2 , -4)

∵ y = -x + b

∴ -4 = -1(2) + b

∴ -4 = -2 + b ⇒ add 2 for both sides

∴ b = -2

- Write the equation with the value of b

∴ y = -x - 2

If that's the case, then we use the Pythagorean Theorem to find the length of the hypotenuse:

28² + 15² = hyp², or

784 + 225 = 1009 = hyp²

Taking the square root of both sides, we get

hyp = 31.8 in

Answer:

third side = 31.8 in

Step-by-step explanation:

Given that two sides of the right angle triangle are 28 in and 15 in.

Now we need to find about what is the third side of the right angle triangle.

So apply the formula of Pythagorean theorem.

[tex](Hypotenuse)^2=(Leg_1)^2+(Leg_2)^2[/tex]

[tex](Hypotenuse)^2=(28)^2+(15)^2[/tex]

[tex](Hypotenuse)^2=784+225[/tex]

[tex]Hypotenuse=\sqrt{1009}[/tex]

[tex]Hypotenuse=31.7647603485[/tex]

Which is approx 31.8.

Hence Length of the third side = 31.8 in.

Final answer:

To find what multiplied by 3/4 equals 1/4, set up the equation 3/4 * x = 1/4 and solve for x, giving the answer x = 1/3.

Explanation:

This question demands basic understanding of multiplication and reciprocals.

The question asks, "3/4 times what equals 1/4?". To find the answer, we can set up the equation 3/4 * x = 1/4, where x is the unknown we are trying to find. Solving for x involves dividing both sides of the equation by 3/4 to isolate x.

Therefore, the equation simplifies to x = (1/4) / (3/4). Performing the division gives us x = 1/3. This means that 1/3 is the number you need to multiply by 3/4 to get 1/4.

To find what number multiplied by 3/4 equals 1/4, divide 1/4 by 3/4, which is the same as 1/4 times the reciprocal of 3/4 (4/3), resulting in 1/3.

To find out 3/4 times what equals 1/4, we are essentially looking for a number that when multiplied by 3/4 gives us 1/4. The mathematical operation we need to use is division since we want to find what 1/4 divided by 3/4 is. So, the equation we are solving is (1/4) ÷ (3/4).

When we divide fractions, we multiply by the reciprocal of the divisor. The reciprocal of 3/4 is 4/3. So, the calculation now is (1/4) × (4/3).

Multiplying the numerators and denominators separately, we get (1 × 4) / (4 × 3) which simplifies to 4/12. After simplification, 4/12 reduces to 1/3. Therefore, 3/4 times 1/3 equals 1/4.
