Two African tigers were
weighed. One weighs 5x + 17
pounds and the two together
weigh 16x + 3 pounds. How
much does the other tiger
weigh alone?
Answer:
Step-by-step explanation:
The weight of the other tiger is 11x - 14.
The total weight of the two tigers is 16x + 3. Subtract the weight of one (5x + 17) from this total; the result is the weight of the other tiger:
16x + 3
- ( 5x + 17)
----------------
11x - 14
The weight of the other tiger is 11x - 14.
George is an artist. He wants to paint a background with congruent squares. If his
canvas is 36 cm by 48 cm, what is the side length of the greatest square possible that
George can use for his background?
Answer:
24 cm
Step-by-step explanation:
For square's to be congruent they must be exactly the same. Also, since squares must have 4 equal sides, both the length and width of the canvas must be divided by the same number in order to give us the longest side. Therefore, since the smallest number we can divide both the width and length by is 2 we are left with 4 equal squares with a size of 18 x 24. Therefore, the longest side length would be 24 cm.

Find the value of x. Classify the triangle by its angles.
Answer: 88 degrees; acute triangle
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees. Therefore, to find the value of "x", the work must look like this: 43+49=92 --> 180-92=88. This triangle can be classified as an acute triangle since all of its angles are acute (less than 90 degrees).

A factory inspector found flaws in 3 out of 18 wooden boxes what is the experimental probability that the next wooden box will be flawed
A factory inspector found flaws in 3 out of 18 wooden boxes. What is the experimental probability that the next wooden box will be flawed?
Write your answer as a fraction or whole number.
-------------------------------------------------------------------------------------------------------------
Remember, The experimental probability is the number of times an event occurs out of the total number of trials.
-------------------------------------------------------------------------------------------------------------
Flawed Boxes / Total
=3/18
=1/6
So The Answer is 1/6
The experimental probability that the next wooden box will be flawed is 1/6=0.167.
What is experimental probability?
The experimental probability of an event is the ratio of the number of outcomes in which a specified events occurs to the total trials.
Mathematically, Experimental probability= f/n, where f is the number of times an event occurs, n is the total number of trials.
Total number of wooden boxes= 18
Total number of boxes that are flawed= 3
Therefore, required experimental probability = 3/18
=1/6
Hence, the experimental probability that the next wooden box will be flawed= 1/6

Answer:
f(2) = 12
f(x) = 7, x = -3, 1
Step-by-step explanation:
a)
plug in x as 2
f(x) = 2^2 + 2(2) + 4
f(x) = 4 + 4 + 4
f(x) = 12
b)
replace f(x) with 7
7 = x^2 + 2x + 4
x^2 + 2x - 3 (move 7 to other side)

Answer:
Step-by-step explanation:
1). By applying Pythagoras theorem in the triangle formed by two sides and the diagonal,
Length of the diagonal = [tex]\sqrt{(\text{side})^2+(\text{side})^2}[/tex]
= [tex](\text{side})\sqrt{2}[/tex]
= 25√2
AC ≈ 35.56 units
2). Since, diagonal of a square is the angle bisector of interior angles of the square,
m∠CAB = 45°
By applying sine rule in ΔABC,
sin(45°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{AB}{AC}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{25}{AC}[/tex]
AC = 25√2
AC ≈ 35.56 units
