4/3 = x/9
Answer:
12
Step-by-step explanation:
[tex] \frac{4}{3} = \frac{x}{9} \\ \\ \implies \: 3x = 4 \times 9 \\ \\ \implies \: 3x =36 \\ \\ \implies \: x = \frac{36}{3} \\ \\ \implies \: x =12[/tex]
Answer:
12
Step-by-step explanation:
or;4/3=X/9
or;3x=4×9
or;3x=36
or;X=36/3
Therefore;X=12

What is the area of a circle with a diameter of 8 centimeters? Use 3.14 for π.
Answer:
50.24 cm^2
Step-by-step explanation:
The formula for the area of a circle is A = πr^2
The radius is half of the diameter so r = 4
So now you can solve:
A = 3.14(4)^2
= 50.24 cm^2
The equation, –2x2 5xy – 7y2 9x – 7y 13 = 0, represents a conic. The discriminant is , so the equation represents a/an.

what is 0.75 divided by 300
Answer:
0.0073
Step-by-step explanation:
<3
Answer:
0.0025
Step-by-step explanation:
This is because , you have the number 75, and dividing that by 3 is 25, but since our number is 0.75, that means we are adding the 2 zeros from our 300 and add it on to be to 0.0025, this won’t work in some situations.
Hope that helps!
kaylin buys a greeting card for $3.79. she then buys 4 postcards that all cost the same amount. the total cost is $5.11. how much is each postcard. show your work
i need the answer today
Answer:
Step-by-step explanation:
Givens
Greeting Card = 3.79
Total Cost = 5.11
Post cards = x
Equation
Total Cost = Greeting Card + 4x
Solution
Substitute the gives into the equation
5.11 = 3.79 + 4x Subtract 3.79 from both sides
5.11 - 3.79 = 3.79 - 3.79 + 4x Combine
1.32 = 4x Divide by 4
1.32/4 = 4x/4
x = 33
Each post card costs 0.33 dollars
A triangle has two sides of length 1 and 14. What is the largest possible whole-number length for the third side?
Answer:
14
Step-by-step explanation:
The triangle inequality is usually expressed as ...
a +b > c
for any permutation of a, b, c.
Here, that would mean ...
1 + 14 > c
c < 15
The largest whole-number value that the third side (c) can have is 14.
_____
Additional comments
Some authors write the triangle inequality as ...
a +b ≥ c
If you use that version, the longest side could be 15. Such a "triangle" would look like a line segment, and have zero area.
__
We can also check the shortest length:
c +1 > 14
c > 13
The smallest whole-number value for the shortest side is also 14. That is, the only triangle with whole-number side lengths of 1 and 14 will be an isosceles triangle with two sides of length 14.

What is the area of this trapezoid?
Enter your answer in the box.
Answer:
80
Step-by-step explanation:
i gotchuuuuu
okok so a really easy way that this can be done is by not doing the full trapezoid, but splitting it up into 2 triangles and 1 rectangle
area of triangle: 1/2BH
area of rectangle: LW
Ookie so first the triangles:
both have the exact same measurements:
7 is the base, and the height is 8. Even tho it doesn't say 8 on one of them, we can visually see that it is the same height.
So, for BOTH triangles, 8*7=56, divided by 2=28.
Now, the rectangle:
width is 3, and length is 8.
8*3=24.
ADD TOGETHER: 28+28+24=80
AREA=80
Answer:
80
Step-by-step explanation:
area of the two triangles
= (7x8)/2x2
= 56
area of the rectangle
= 8x3 = 24
area of the trapezoid
= 56+24
=80

will award brainliest
Answer:
a = 92° , b = c = 143°
Step-by-step explanation:
a and 88° are same- side interior angles and sum to 180° , that is
a + 88° = 180° ( subtract 88° from both sides )
a = 92°
b and 37° are same- side interior angles and sum to 180° , then
b + 37° = 180° ( subtract 37° from both sides )
b = 143°
b and c are corresponding angles and are congruent , then
c = b = 143°

What is the ordered pair in the solution set of 0. 5x-2y=3
Answer:
See Below
Step-by-step explanation:
The left side of the equation HAS TO BE GREATER THAN 3
So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.
A:
0.5x - 2y
0.5(-2) -2(0.5) = -2
NO
B:
0.5x - 2y
0.5(2) -2(1) = -1
NO
C:
0.5x -2y
0.5(2) -2(-1) = 3
NO
D:
0.5x -2y
0.5(-2) -2(-0.5) = 0
NO
None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.
