Answer: 21/4 or 5 1/4
Step-by-step explanation: sorry for the 21/4 if this is wroNG IM SOOO SORRy if it is..
Ok so first find the area on the triangle where is gives the length and width and the formula for the area of a triangle is Length x widthsx 0.5 so 5.2x8x0.5=20.8 square inches . Then to find the area of the other triangle you have to use Pythagorean’s theorem to find the length because we know the hypotenuse is 6.8 and the width is the same as the other side so width is 5.2 the we will do a^2=c^2-b^2 so a^2=6.8^2-5.2^2 a^2=46.24-27.04 a^2= 19.2 and the square root of 19.2= 4.38 so find the area of that triangle 5.2x4.38x0.5=11.4 square inches then add the two areas together to get 32.2 square inches
Product is multiplication.
A number and 4 : 4x
Increase by 1 : +1
Put it together:
4x + 1 = -3
Twelve less than: -12
A number: x
Three more than: +3
Four times a number: 4x
Put it together:
x - 12 = 4x + 3
Answer:
40%
Step-by-step explanation:
Total amount of marbles are 25
the chances of getting green marbles out of all the marbles are 10/25 or 0.4
and since we are looking for percentages we have to multiply 0.4 by 100
0.4 x 100 = 40
