Step-by-step explanation:

Count by 6

The co-efficient value is "4 and 3".

[tex]\to 4x + 3y = 7[/tex]

Using the standard form to calculate value:

[tex]\to ax+bx+c=0[/tex]

compare the above value:

[tex]\to 4x + 3y -7=0\\\\\to ax + by +c=0\\\\[/tex]

co-efficient of x = 4

co-efficient of y = 3

constant term= -7

Therefore, the final answer is "4,3".

Given:

Consider the below figure attached with this question.

Perimeter of triangle ABC is 13 cm.

Triangle ABC is dilated to create the triangle A'B'C'.

To find:

The perimeter of triangle A'B'C'.

Solution:

We know that, dilated figures are similar.

[tex]\text{Scale factor}=\dfrac{\text{Side of image}}{\text{Corresponding side of preimage}}[/tex]

[tex]\text{Scale factor}=\dfrac{OB'}{OB}[/tex]

[tex]\text{Scale factor}=\dfrac{5+15}{5}[/tex]

[tex]\text{Scale factor}=\dfrac{20}{5}[/tex]

[tex]\text{Scale factor}=4[/tex]

Perimeters of similar figure is proportional to the corresponding sides of that figure or equal to the scale factor.

[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{\text{Perimeter of }\Delta ABC}=\text{Scale factor}[/tex]

[tex]\dfrac{\text{Perimeter of }\Delta A'B'C'}{13}=4[/tex]

Multiply both sides by 13.

[tex]\text{Perimeter of }\Delta A'B'C'=13\times 4[/tex]

[tex]\text{Perimeter of }\Delta A'B'C'=52[/tex]

Therefore, the perimeter of triangle A'B'C' is 52 cm.

It required 332 weeks to pay the whole amount.

Given that,

Amount to repay = $4308
Amount to be repaid in a week = $13
The number of weeks that will be consumed is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Let the number of weeks be x,
By arithmetic operations

13x = 4308
x = 4308 / 13
x = 331.34
x ≈332 weeks

Thus, It required 332 weeks to pay the whole amount.

Answer:

[tex]12\:\mathrm{ft}[/tex]

Step-by-step explanation:

When the ladder is leaning against the wall, a 30-60-90 triangle is formed. The ladder acts as a 24-foot hypotenuse. Because the height is facing the [tex]30^{\circ}[/tex] angle, the height is half the hypotenuse (30-60-90 rules). If you forget the side rules for a 30-60-90 triangle, simply use basic trig on the right triangle:

[tex]\sin 30^{\circ}=\frac{h}{24},\\h=24\sin 30^{\circ},\\h=24\cdot \frac{1}{2},\\h=\fbox{$12\:\mathrm{ft}$}[/tex].

Answer:

106

Answer: 181.82

Explanation:

Step 1: We make the assumption that 22 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100%=22.

Step 4: In the same vein, x%=40.

Step 5: This gives us a pair of simple equations:

100%=22(1).

x%=40(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the left hand side of both equations have the same unit (%); we have

100 percent/X percent = 22/40

Step 7: Taking the inverse (or reciprocal) of both sides yields

100 percent/X percent = 40/22

X = 181.82%

Therefore, 40 is 181.82% of 22.

Answer:

The value of [tex]x[/tex] is 10º.

Step-by-step explanation:

From Euclidean Geometry we remember that the sum of internal angles within a triangle equals to 180º. We present the resulting triangle after applying some geometric handling in the image attached below. Then, the triangle satisfies the following equation:

[tex]100^{\circ} + (80^{\circ}-5\cdot x)+(4\cdot x +10^{\circ}) = 180^{\circ}[/tex] (1)

[tex]190^{\circ} - x = 180^{\circ}[/tex]

[tex]x = 10^{\circ}[/tex]

The value of [tex]x[/tex] is 10º.

Step-by-step explanation: divide the price of certain number of units of an item by the number of units to find the unit price of that item.

EX: To find the unit price of 12 ounces of soup that costs $2.40, divide $2.40 by 12 ounces, to get unit price of soup as $0.20 per ounce.

Answer:

The equation of the Parallel line passes through the point (-1,4) is

y = -5 x -1

Step-by-step explanation:

Explanation:-

Given the equation of the line y = -5 x + 2

Given point (-1 , 4 )

The equation of the parallel line of a given line is 5x + y +k=0 ...(i)

The equation (i) passes through the point (-1,4)

                 5(-1)+4+k=0

                -5 +4 +k =0

                    -1 + k = 0

                         k = 1

The equation of the Parallel line passes through the point (-1,4) is

   y = -5 x -1

The value of 3(2)ˣ for x = -1 is 3/2

In mathematics, simply or simplification is reducing the expression/fraction/problem to a simpler form. It makes the problem easy with calculations and solving.

Given is a function, f(x) = 3(2)ˣ

When x = -1

f(-1) = 3(2)⁻¹

f(-1) = 3x2⁻¹

f(-1) = 3x1/2

f(-1) = 3/2

Hence, The value of 3(2)ˣ for x = -1 is 3/2

Answer:

[tex]k=\frac{4}{7}[/tex]

Step-by-step explanation:

The equation [tex]y=kx[/tex] represents a proportional relationship that always passes through the origin. Excluding of the origin, you can plug any [tex](x,y)[/tex] coordinate into this function to get [tex]k[/tex].

Using the first coordinate, we have:

[tex]4=k(7),\\k=\frac{4}{7}[/tex]

Verify that [tex]y=kx[/tex] works for the other coordinates [tex]\checkmark[/tex]

Thus, the value of constant [tex]k[/tex] is [tex]\fbox{$\frac{4}{7}$}[/tex].
