3 ( 11× + 9×) = 6

33× + 27× = 6

60× = 6

× = 6/60

× = 0.1 ans

Given tz/zx=tw/wy. if tx =53, find ty

s2008m [1.1K]

Answer:

ty = 53

Step-by-step explanation:

Given

$\frac{tz}{zx}$ = $\frac{tw}{wy}$

Cancel the z on the numerator/denominator of the left side and

Cancel the w on the numerator/denominator of the right side, leaving

$\frac{t}{x}$ = $\frac{t}{y}$

Cross- multiply

ty = tx ← tx = 53, hence

ty = 53

one container is filled with a mixture that is 30% acid a second container is filled with the mixture that is 50% acid the secon

Romashka [77]

Answer:

42%

Step-by-step explanation:

x is for the volume of the container

the amount filled in the first container=0.30x

the volume of the first container + 50% of the second=(x+x*50%)=1.5 x

the amount of acid in the second container= 1.5x * 50%=0.75x

total amount of acid in the third one =0.3x+0.75x=1.05x

total solution : x+1.5x=2.5x

percentage=1.05x/2.5x= 0.42 or 42%

Does anyone know how to do this ?

Answer: D) 32

Step-by-step explanation:

The area of a parallelogram equals its base times its height. Substitute the base and area into this formula to solve for the height:

A=bh

40=(5)(h)

h=8

If ABCD is a parallelogram, opposite sides are parallel, so AB is parallel to DC. If AB is parallel to DC, EB is parallel to DC. Since EB is parallel to DC, quadrilateral EBCD has at least one pair of parallel sides, making it a trapezoid. The area of a trapezoid is equal to $\frac{h(b_{1}+b_{2}) }{2}$ where h is the height, $b_{1}$ is one base, and $b_{2}$ is the other base. Plug the necessary values into the formula:
