Question 3: i’ll mark u brainliest

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.

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].

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

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.

Hello!

[tex]\large\boxed{A = 66ft^{2}}[/tex]

Formula for the area of a rectangle:

A = b × h where:

b = base

h = height

We are given the base and height as 11 ft and 6 ft, so use the equation above to solve for the area:

A = 11ft × 6ft

A = 66ft²

$100 because if you follow the line from 5 hours to the line it lines up with 100 dollars

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".

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: 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.
