A sheet of glass has a density of 2.5 g/cm3. what is the density of the glass in kg/m3
asambeis [7]

Answer:

this is ez

Step-by-step explanation:

2.5 g converted to kg: 2.5 g x 1 kg/1000 g = 0.0025 kg = 2.5x10-3 kg

cm3 converted to m3: 1 cm3 x 10-6 m3/cm3 = 1x10-6 m3

Thus, the conversion of 2.5 g/cm3 to kg/m3 would be 2.5x10-3 kg/10-6 m3 = 2.5x103 kg/m3 = 2500 kg/m3

Find the equation for intercept x 4 and y -7​
nadezda [96]

Answer:

y = \frac{-7x}{4} - 14

Step-by-step explanation:

The equation used to find the equation for a line with two intercepts is called point slope form. y - y_{1} = m(x - x_{1}) , where y_{1} and x_{1} are the intercept points and m is the slope.

However, we need the slope to use this formula.

Use m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{y_{1} - y_{2} }{x_{1} - x_{2}}

m = \frac{((0) - (7))}{((4) - (0))}

m = \frac{-7}{4}

y - y_{1} = m(x - x_{1})

y - ( -7 ) = m ( x - ( 4 ) )

y - ( -7 ) = -7/4 ( x - ( 4 ) )

y + 7 = -7/4 ( x + 4 )

y + 7 = \frac{-7(x+4)}{4}

y + 7 = \frac{-7x-28}{4}

y + 7 = \frac{-7x}{4} - 7

y + 7 = \frac{-7x}{4} - 7 - 7

y = \frac{-7x}{4} - 14

Roger is a florist who uses a triangular-shaped frame to arrange flower bouquets. He received an order to make a new bouquet suc
kvv77 [185]

The locations specified in the order regarding the shape will be B. longest side AC; smallest angle ∠C.

<h3>How to express the information?</h3>

From the information given, in the triangle where A = 59°, B is unknown, and C = 41°. Therefore, the value of B will be:

= 180° - (59° + 41°)

= 180° - 100°

= 80°

Therefore, the locations specified in the order regarding the shape will be longest side AC; smallest angle ∠C.

In conclusion, the correct option is B.

Find the equation of the line using the point-slope formula. Write the final equation using the slope-intercept form. the x-inte
wariber [46]

Step-by-step explanation:

Given x intercept is 1, So (x,y) is (1,0)

When x intercept is 1 then y  value is 0

Another point on the line is (-2,3)

Two points are (1,0) and (-2,3)

Find out slope using the two given points

slope m=\frac{y_{2}-y_1}{x_2-x_1} =\frac{3-0}{-2-1} =-1\\m=-1

Use point slope formula

m=-1 and point(1,0)

y-y_{1}=m(x-x_{1})\\y-0=-1(x-1)\\y=-1x+1

Point slope equation is

y-0=-1(x-1)

Equation of the line in slope intercept form is

y=-1x+1
