Are 25 milligrams lighter or heavier than 25 centigrams
Please help it's for homework and it says explain too so please help
Answer:
25 mg. is lighter than 25 cg.
Step-by-step explanation:
Well,
The prefix "milli" means thousandth and the prefix "centi" means hundredth. So a milligram will be one-tenth of a centigram.
10 mg. = 1 cg.
25 mg. = 2.5 cg.
2.5 cg. < 25 cg.
25 mg. is lighter than 25 cg.
Answer:
25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Karl is replacing his concrete driveway with rectangular pavers. Each paver has an area of 4.5 square feet. Karl's driveway is 21 feet long and 18 feet wide. How many pavers will he need?
Answer:
84
Step-by-step explanation:
To complete the concrete highway with pavers 84 pavers are needed.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
From the given information each Pavel has an area of 4.5 square feet.
And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,
= (21×18) sq feet.
= 378 sq feet.
Therefore, The number of pavers needed is,
= (378/4.5).
= 84 pavers.

Equation that has a slope of -4 and passes through the point (-2, 2) show work too
Answer:
y=-4x-6
Step-by-step explanation:
y=mx+b, where m is the slope and b is the y-intercept
Slope is given as -4, so:
y=-4x+b
To find b, sub in the point we were given (-2,2):
2=-4(-2)+b
2=8+b
b=2-8=-6
So we have: y=-4x-6

Answer:
a. sin 30* = sin 150*
b. sin 1* = sin 179*
a. cos 340* = cos 20*
b. cos 260* = cos 100*
Step-by-step explanation:
sine is symmetrical around x = 90*
cosine is symmetrical around x = 180*
* means degree sign of course.
The figure below shows a line graph and two shaded triangles that are similar:
A line is shown on a coordinate grid. The x axis values are from negative 20 to positive 20 in increments of 4 for each grid line. The y axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 16, negative 4, and 0, 0, and 16, 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 8, negative 2 labeled as A, one leg is from 0, 0 to 0, negative 2, and the second leg is from 0, negative 2 to negative 8, negative 2. Another shaded right triangle is formed with the hypotenuse from negative 8, negative 2 to negative 12, negative 3 labeled as B, one leg is from negative 8, negative 2 to negative 8, negative 3, and the second leg is from negative 12, negative 3 to negative 8, negative 3.
Which statement about the slope of the line is true?
A. The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.
B. The slope from point O to point A is 4 times the slope of the line from point A to point B.
C. It is 4 throughout the line.
D. It is fraction 1 over 4 throughout the line.
The answer should be D

28>6x-2
Answer:
5 > x
Step-by-step explanation:

(add 2 to both sides)
30 > 6x
(divide through by 6)
5 > x
Answer:
x < 5
Step-by-step explanation:
Given
28 > 6x - 2 ( add 2 to both sides )
30 > 6x ( divide both sides by 6 )
5 > x , that is
x < 5
x = 3y + 4

Pythagorean theorem - please help
answer:
x = 4[tex]\sqrt{2}[/tex] or 5.6568
step-by-step explanation:
know the formula and plug informula: a^2 + b^2 = c^2
now plug in what we havewhatever the RIGHT ANGLE points to is the HYPOTENUSE or cthe other two sides are the "legs" or a and ba^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4[tex]\sqrt{2}[/tex]
in this case, b would be used as xx = 4[tex]\sqrt{2}[/tex] or 5.6568 (exact value)
