Are you allowed to use a calculator? if you are allowed, for number 13 you should put “If you put 678 into a calculator and divide it by 2, you get 339. If you divide it by 3, you get 226. And if you divide it by 6, you get 113.”They are all numbers without decimals.
I’m not sure about 14 though. Sorry :( But i hope i helped.
Currently there is nothing available for reversal of dilation. People who get dilated will still need to wear their sunglasses and to put off reading for a couple of hours until the effects of the dilation drops wear off.
Answer:
49
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.Laura's design will be light enoughThe shape is given as a trapezium (see attachment).First, calculate the height (h) of the trapezium using the following Pythagoras theorem 52=h2+x2 Where: x=11−92=1 So, we have: 52=h2+x2 52=h2+1225=h2+1 Collect like terms h2=25−1 h2=24 Take square root sh=4.90The area of the shape is then calculated as follows: Area=12(11+9)×h Area=12(11+9)x4.90 Area=12×20×4.90 Area=10×4.90 Area=49
The area of the shape is 49 square inches.Hence, the shape will be light enough (because 49 is less than 80
(4, 2) and (8, 1) (option D)
Explanation:
The given equation:
y = 4x - 1
comparing with equation of line:
y = mx + c
m = slope = 4
c = y-intercept = -1
For a line to be perpendicular to another line, the slope of one line will be the negative reciprocal of the other line.
We need to find the option which will give a negative reciprocal of 4.
a) (1, -3) and (2, 1)
b) (-4, 7) and (-1, -5)
c) (-8, -4) and (0, -2)
d) (4, 2) and (8, 1)
slope = 4
reciprocal of 4 = 1/4
negative reciprocal = - 1/4
Hence, the option whose slope gives the negative reciprocal of 4 is (4, 2) and (8, 1) (option D)
Answer:
-3x²-10x+3
Step-by-step explanation:
if A=2x-7x²+3 and B=4x²-12x, then A+B:
(2x-7x²+3)+(4x²-12x)=-3x²-10x+3.
