kareena uses 1 1/4 yards of frabic to make one tote 2 1/2 of frabic to make tote and 3 3/4 yards of rabbit to make three totes she continues to use the same amount of frabic for each tote how many yards of fabric will she need to make four totes​

Answers

1 = 1 1/4
2 = 2 1/2
3 = 3 3/4

Multiply 1 1/4 x the number of totes, and you’ll have your total.

4 x 1 1/4 = 4 4/4 = 5 yards

The next model of a sports car will cost 12.2% less than the current model. The current model costs $34,000 . How much will the price decrease in dollars? What will be the price of the next model?

Answers

Answer:

Price decrease in dollars = $4,148Price of next model = $29,852

Step-by-step explanation:

The next car will be 12.2% cheaper. This amount in dollars is:

= Percentage decrease * Current model price

= 12.2% * 34,000

= $4,148

The price of the next model will therefore be:

= 34,000 - 4,148

= $29,852

Find the size of angle x.
Give your answer correct to 1 decimal place.

Answers

Answer:

x ≈ 31.0°

Step-by-step explanation:

From the right triangle given in the picture,

By applying tangent rule,

tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(x) = [tex]\frac{9}{15}[/tex]

x = [tex]\text{tan}^{-1}(\frac{9}{15} )[/tex]

x = [tex]\text{tan}^{-1}(0.6)[/tex]

x = 30.96

x ≈ 31.0°

Therefore, measure of angle x is 30.0°

Find the value of x using the corresponding angles theorem.

Answers

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

---------------

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4

The quotient of 9x³ - 21x² + 12x divided by 3x is  3x² - 7x + 4.

What is a factor of a polynomial?

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial 9x³ - 21x² + 12x and being divided by 3x.

So, (9x³ - 21x² + 12x)/(3x).

= 9x³/3x - 21x²/3x + 12x/3x.

= 3x² - 7x + 4.

So, The quotient when 9x³ - 21x² + 12x and being divided by 3x is

3x² - 7x + 4.

Slope intercept form

Answers

Given:

The equation of the parallel line is

[tex]y=-\dfrac{5}{2}x+7[/tex]

The required line passes through the point (-4,1).

To find:

The equation of line in slope slope intercept form.

Solution:

The slope intercept form of a linear function is

[tex]y=mx+b[/tex]

Where m is slope and b is y-intercept.

On comparing the equation [tex]y=-\dfrac{5}{2}x+7[/tex] with slope intercept form, we get

[tex]m=-\dfrac{5}{2}[/tex]

We know that the slopes of parallel lines are always same. So, the slope of the required line is [tex]m=-\dfrac{5}{2}[/tex].

The line passes through the point (-4,1) with slope [tex]m=-\dfrac{5}{2}[/tex]. So, the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(1)=-\dfrac{5}{2}(x-(-4))[/tex]

[tex]y-1=-\dfrac{5}{2}(x+4)[/tex]

[tex]y-1=-\dfrac{5}{2}x-10[/tex]

Adding 1 on both sides, we get

[tex]y=-\dfrac{5}{2}x-10+1[/tex]

[tex]y=-\dfrac{5}{2}x-9[/tex]

Therefore, the correct option is C.

The angle of this vector form is given by :

[tex]\tan\theta=\dfrac{y}{x}\\\\\tan\theta=\dfrac{9}{-5}\\\\\tan\theta=-1.8\\\\\theta=\tan^{-1}(-1.8)\\\\=-60.94^{\circ}[/tex]

So, the angle of this vector is -60.94°.

A line passes through the point (-6,9) and has a slope of -5/2 . Write an equation in point-slope form for this line.

Answers

Answer:

y-9=-5/2(x+6)

Step-by-step explanation:

y-y1=m(x-x1)

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

An equation in point-slope form for this line would be y-9=-5/2(x+6).

What is the Point-slope form?

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

Thus,

y-y1= m(x-x1)

A line passes through the point (-6,9) and has a slope of -5/2 So,

y-9=-5/2(x-(-6))

y-9=-5/2(x+6)

Hence, an equation in point-slope form for this line would be y-9=-5/2(x+6).
