Answer:

B? I believe? sorry if it's wrong

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

3 = x

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

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.

I THINK I GOT IT OMG THAT WAS SO HARD

Answer:

z = 5

Step-by-step explanation:

[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]

It can be also written as -

[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]

Using law of exponents , lets solve this.

[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]

[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]

[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]

[tex]=> y^z = y^5[/tex]

[tex]=> z = 5[/tex]

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.

4x(5-4y)

Answer:

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:

226.2

Step-by-step explanation:

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]
