I took the test. I hope this helps! :)

The area of the circular lace is required.

The smallest circular piece of lace to cover the entire top of the table is 226.2 inches².

Length of each side of square = 12 inches

The diameter of the circle will be the length of the diagonal of the square from the given figure.

[tex]d=\sqrt{12^2+12^2}\\\Rightarrow d=12\sqrt{2}\ \text{in}[/tex]

Area of a circle is given by

[tex]A=\pi\dfrac{d^2}{4}\\\Rightarrow A=\pi \dfrac{(12\sqrt{2})^2}{4}\\\Rightarrow A=226.194\approx 226.2\ \text{in}^2[/tex]

Answer:

The acceleration of an object varies directly as the force acting on it. If a force of 240 newtons causes an acceleration of 150 m/s², what force will cause an acceleration of 100 m/s?? 2. The stretch in a loaded spring varies directly as the load it supports.

Answer:

160 Newtons

Step-by-step explanation:

240÷150= 1.6. 100x1.6 gives us the answer which is 160 Newtons for 100m/s. For every 1.6 newtons,1 m/s is gained.

Answer: 21 questions

Step-by-step explanation:

Turn it into a number sentence.

72% of x amount of questions is 15

0.72(x) = 15. Divide both sides by 0.72

x= 20.83333 round to nearest whole number

x= 21 questions

Answer:

x = 3

Step-by-step explanation:

use the substitution method

since y = 6 fill in 6 for y in y = -5x + 21

6 = -5x + 21

subtract 21 from both sides

-15 = -5x

divide each side by -5

First option,   [tex]\frac{-2y+5x}{3x-2y}[/tex]

Step-by-step explanation:

Simplify the fraction. To make the process of solving easier, we can multiply both the numerator and denominator by x and y to get rid of the fractions as seen below. This is because the variables in the denominators of the fractions will cancel out with either the matching x or y in the numerators.  

[tex]\frac{\frac{-2}{x} +\frac{5}{y} }{\frac{3}{y}-\frac{2}{x} } \\=\frac{(\frac{-2}{x} +\frac{5}{y})xy }{(\frac{3}{y}-\frac{2}{x})xy }\\=\frac{-2y+5x}{3x-2y}[/tex]

Thus, the first option is correct.

Answer:

$55.20

Step-by-step explanation:

Create a proportion where x is the cost of 12 lbs of walnuts:

[tex]\frac{3.45}{0.75}[/tex] = [tex]\frac{x}{12}[/tex]

Cross multiply and solve for x:

0.75x = 41.4

x = 55.2

So, for 12 lbs of walnuts, it will cost $55.20

Answer:

6x² - 17x + 12

Step-by-step explanation:

Given

(2x - 3)(3x - 4)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(3x - 4) - 3(3x - 4) ← distribute both parenthesis

= 6x² - 8x - 9x + 12 ← collect like terms

= 6x² - 17x + 12

Answer:

Step-by-step explanation:

area = ½×base×height

21 = ½(x+1)x

42 = (x+1)x

x² + x - 42 = 0

(x+7)(x-6) = 0

x = -7, 6

-7 is an extraneous solution, so x = 6

A triangle is a three-edged polygon with three vertices. The value of x is 6.

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.

The area of the triangle is half the product of the base of the triangle and the height of the triangle.

Given that base of the triangle is x+1, while the height of the triangle is x. Also, the area of the triangle is 21 units².

Area of triangle = (1/2) ×  height of the triangle × length of the base

21 = (1/2) × x × (x+1)

21 = (1/2)(x² + x)

21 × 2 = x² + x

42 = x² + x

x² + x - 42 = 0

x² + 7x - 6x - 42 = 0

x(x + 7) - 6(x + 7) = 0

(x + 7)(x - 6) = 0

x = -7, 6

Now, since the value of x can not be negative. Therefore, the value of x is 6.

Hence, the value of x is 6.

I took the quiz

Answer: 460 students

Step-by-step explanation:

Based on the information given in the question, let the total number of students that attend I.S. 59 be represented by x.

Since we've been given the information that 230 signed up for the school picnic which was 50% of all students in the school. Then, the students in the school will be:

= 50% of x = 230

0.5 × x = 230

0.5x = 230

x = 230/0.5

x = 460

Therefore, 460 students attend the school.

Answer:Weight of wood part of the sculpture  (no decimals) =4kg

Step-by-step explanation:

Weight of sculpture containing metal and wood   = 14.9 kg

weight of metal =3/4 x 14.9 kg =11.175kg

weight of wood =Entire sculpture − weight of metal

 = 14.9 kg−11.175kg

  =3.725kg

Rounding up to remove decimals  we have that Weight of wood part  =4kg
