Answer:
B. 90; 100 is a reasonable estimate
Step-by-step explanation:
15 + 14 = 29 (combined number of stamps Julissa and Ethan have)
Pawel has three times 29 stamps
29 ×3 = 87 (number of stamps Pawel has)
90 is the closest estimate to the amount of stamps Pawel has.
Therfore, 90 is the correct estimate and 100 is a reasonable estimate.

Please help me with this math problem!! :) I will mark brainliest!! :)
Answer:
x = 36
Step-by-step explanation:
180 - 48 = 132
This is because angle AC- and ACB form a straight angle (180 degrees).
132 + 12 = 144
180 - 144 = 36
The three interior sides of a triangle always add up to 180 degrees.
Hope this helps!
I WILL GIVE YOU BRAINLIST Liam and kiki are tigers living at the libertyville zoo. Liam weights 7 pounds for every 4 pounds that Kiki weighs. If Liam is 90 pounds more than Kiki, how many pounds does he weigh?
Step-by-step explanation:
Let L= Liam's weight, and K = Kiwi's weight.
We know that L/K = 7/4
We also know that L = K + 90
Rearrange the first equation to find K:
L/K = 7/44L = 7KK = (4/7)LNow use K = 4L/7 in the second equation:
L = K + 90L = (4/7)L + 90(3/7)L = 90L = (90)*(7)/3L = 630/3L = 210 lbsCheck the math:
If L = 210, then K must be L - 90, or 120 pounds
Does L/K = 7/4?
(L/K) = (210/120) = 7/4 YES
How to solve for x in this?
Answer:
x = 80 degrees
Step-by-step explanation:
Let's say the angle ABC = 30 degrees and angle BAC = x degrees
angle ACB = 180 - 110
angle ACB = 70 degrees
angle BAC = 180 - angle ABC - angle ACB
x = 180 - 30 -70
x = 150 - 70
x = 80 degrees

Find the rate of change between:
(1,4)
(5,2)
Answer:
-1/2
Step-by-step explanation:
In a function, the rate of change from x = a to x = b is
rate of change = [f(b) - f(a)]/(b - a)
Here we have
a = 1, f(a) = 4
b = 5, f(b) = 2
rate of change = (2 - 4)/(5 - 1)
rate of change = -2/4 = -1/2

In the standard form of a quadratic function, the ___ value tells me the y-intercept.
c
a
b
x
Answer:
c
Step-by-step explanation:
y-intercept is the function value at x = 0, and we can always substitute x = 0 into the quadratic. Thus, the y-intercept of the quadratic function
y = ax2 + bx + c is c.

Factor the expression
x2 + 4xy - 117y2?
Lets Factorize the given expression:-
[tex]️{x}^{2} + 4xy - 117 {y}^{2} [/tex]
Splitting the middle term :-
[tex]{x}^{2} - 9xy + 13xy - 117 {y}^{2} [/tex]
[tex]( {x}^{2} - 9xy) + (13xy - 117 {y}^{2})[/tex]
[tex]x(x - 9y) + 13y(x - 9y)[/tex]
[tex](x - 9y)(x + 13y)[/tex]
So, the final answer is:-
[tex](x - 9y)(x + 13y)[/tex]
Work out the perimeter of the shaded shape.
Find the area of the unshaded region in Fig, where ABCD is a square of side 20 cm and semicircles are drawn with each side of the square as diameter. (Use π = 3.14)
Answer:
229
Step-by-step explanation:
Area of square is = 20 * 20 = 400
radius = 20 / 2 = 10
Area of semi circle is = 1/2 * πr²
= 1/2 * 3.14 * 10²
= 1/2 / 314
= 157
assume there are four shaded regions for the figure
Area of 4 semicircles−Area of shaded region=Area of square ABCD
Area of shaded region=Area of 4 semicircles−Area of square ABCD
= 4 * 157 - 400
= 628 - 400
= 228
so each single shaded area is 228/4
= 57
now in your problem there are 3 shaded regions like this
so area of unshaded region is =
Area of square - 3 * shaded region area of one region
=> 400 - 3 * 57
=> 400 - 171
=> 229
