What should be the paper weight
nata0808 [166]

Answer:

6.25 cm

Step-by-step explanation:

\rho=\dfrac{m}{V} \\\\V_{\text{pyramid}}= A_{\text{base}}\cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{V} \\\\V=120 \cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{40h} \\\\1.6=\dfrac{10}{h} \\\\1.6h=10 \\\\h=\dfrac{10}{1.6}=6.25\text{ cm}

Hope this helps!

Determine the intercepts of the line. <br> -5x-4y=10
storchak [24]

Answer:

x-intercept:(-2,0)\\\\y-intercept:(0,-\frac{5}{2})

Step-by-step explanation:

The y-intercept is where x is 0 (0,y)

The x-intercept is where y is 0 (x,0)

Insert 0 as the value for x to find the corresponding y value:

-5(0)-4y=10

Simplify multiplication:

0-4y=10\\\\-4y=10

Isolate the variable. Divide both sides by 4:

\frac{-4y}{4}=\frac{10}{4}  \\\\-y=\frac{10}{4} \\\\-y=\frac{5}{2}

Make the variable positive. Multiply both sides by -1:

-1(-y)=-1(\frac{5}{2})\\\\y=-\frac{5}{2}

The y-intercept is at (0,-\frac{5}{2}).

Insert 0 as the value for y to determine the value of x:

-5x-4(0)=10

Simplify multiplication:

-5x-0=10\\\\-5x=10

Isolate x. Divide both sides by 5:

\frac{-5x}{5} =\frac{10}{5} \\\\-x=2

Multiply both sides by -1:

-1(-x)=-1(2)\\\\x=-2

The x-intercept is at (-2,0).

A patio on the scale drawing is 4 cm long. The scale used is 1 cm represents 5.5 feet. How long is
DochEvi [55]

The patio is 22 feet long.

The act of measuring is the practice of comparing a physical quantity with a recognized standard quantity of a like kind. A base unit, sometimes called a fundamental unit, is a unit used to quantify a base amount. A base quantity is a physical quantity that is part of a traditionally selected subset of physical quantities but cannot be stated in terms of the other physical values in the subset.

Given the scale used is 1cm which represents 5.5 feet.

measure of patio on scale drawing is 4cm.

then  it's length is 5.5 × 4 = 22 feet

These measurements pertain to the following: length, mass, time, electric current, temperature, amount of a substance, and luminance. Here are the seven base units' definitions: Distance: meters (m) Metric length is measured in meters.

hence we get the value of the length of the patio as 22 feet.
