Answer:
C
Step-by-step explanation:
She needs 1/4 c and 1/2 c (or 1/2 and 1/4, it's the same both ways because it is addition)
A shows 1/2 and 1/4
B shows 2/8 (which can be reduced to 1/4) and 4/8 (which can be reduced to 1/2)
C shows 1/2 and 4/8 (which can be reduced to 1/2)
D shows 4/8 (which can be reduced to 1/2) and 1/4
so the only choice that does not show the correct about of butter (1/2 and 1/4) is answer C (the one in the bottom left corner)
You have to find the unit rate
SO..
7.70 / 154 = 0.05
So it cost her 0.05 cents for each text.
So then you divide $ 5.25 by the unit rate to get the number of text
5.25 /0.05 = 105
so she sent 105 text
To check it you just multiply the unit rate by the number of text you got and you show come up with $ 5.25
0.05 x 105 = 5.25
Answer: 6.75 feet
Step-by-step explanation:
Since, the ratio of the side of the similar triangle = 2 : 3
Thus, by the property of similar triangle,
The ratio of the altitudes of the triangle = 2 : 3
Let the altitude of smaller triangle = 2 x
And, the altitude of larger triangle = 3 x
Where x is any number.
According to the question,
2 x = 4.5
x = 2.25
Therefore, the altitude of larger triangle = 3 × 2.25 = 6.75 feet
Answer:
1.x^2-5x
2.2x^2+15x+18
3. x^2+20x+18
Step-by-step explanation:
1. x(x-5) x*x-5*x = x^2-5x
2. (x+6)(2x+3) x*2x+x*3+6*2x+6*3= 2x^2+15x+18
3.(2x^2+15x+18)-(x^2-5x)=x^2+20x+18
