Answer:
Step-by-step explanation:
4⅖ = 22/5 = 242/55
-3 2/11 = -35/11 = -175/55
k = -175/55 - 242/55 = -417/55 = -7 32/55
X / 40 = 4 /32 ( similar triangles)
x / 40 = 1 / 8
x = 40/8 = 5 answer
Answer:
1.5gal
Step-by-step explanation:
From the given information:
50% lemon juice + 50% lime juice is the intended mixture.
Therefore, to find quantity that would be added to 20% lemon juice and 80% lime juice, let's assume this to be x.
x of 100% and 4-x gallons of the existing 20% mix
100%x + 20%(4-x) = 50%(4)
1.00x + 0.2(4-x) = 0.5(4)
1.00x + 0.8-0.2x = 2
1.00x-0.2x = 2-0.8
0.8x = 1.2
× = 1.5gal.
She can type 4,800 words in one hour.
1.B - - original function is y = sqrt(x). If we make sqrt(x+4), we will move the original function to the left 4. If we make sqrt(x+4)+3, additionally the original function will be moved up 3.
2.D - original function is y = sqrt(x). If we make sqrt(x-7), we will move the original function to the right 7. If we make 5*sqrt(x-7), additionally the original function will be expanded throw the y-axis.
3.E - original function is y = x^5. If we make -x^5 (multiply x^2 by -1), we will reflect the original function over the x-axis. If we make -x^5 - 4 , we additionally will move the original function down 4.
4.C - original function is y = x^2. If we make (x-3)^2, we will move the original function to the right 3. If we make x^2 - 5 , we will move the original function down 5.
5.A - original function is y = x^2. If we multiply x^2 by 1/3, function will be compressed about the y-axis.
