Answer:

A, C, E, F, G

Step-by-step explanation:

let's actually solve the inequality -7x+14>-3x-6:

Adding 7x to both sides simplifies the inequality to 14> 4x-6.

Adding 6 to both sides isolates 4x: 20 > 4x.

Finally, dividing both sides by 4 yields 5 > x, or x < 5.

We must now determine which of the possible solutions A-G are less than 5:

A, C, E, F, G

Answer:

(b)(i) LCM of 45 and 50 = 450

Hence, it take 450 minutes until both ovens ding simultaneously.

(b)(ii) 450÷50=9 banana cakes baked

450÷45=10 chocolate cakes baked.

Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for

mixas84 [53]

Answer:

squid, crab, tuna, eel

Step-by-step explanation:

Just make each sushi piece into an equation, then solve it.

For example, for the squid: (s stands for squid)

$2s = 3.5\\ s=1.75$ Divide both sides by 2 to get "s" by itself

Eel: (e stands for eel)

e = 3.25

Tuna: (t stands for tuna)

$3t=6.75\\ t=2.25$ Divide both sides by 3 to get "t" by itself

Crab: (c stands for crab)

$4c=8\\ c=2$ Divide both sides by 4 to get "c" by itself

**Then order from least to greatest**

The cable railway was driven by a 8 foot diameter drum that turned 13 revolutions per minute. Find the linear velocity of the ca

slava [35]

Answer:

The linear velocity of the cable ≅ 327 feet per minute.

Step-by-step explanation:

Given that the diameter of the drum = 8 feet

Radius of the drum = $\frac{diameter}{2}$

= $\frac{8}{2}$

= 4 feet

Radius of the drum = 4 feet

1 revolution = circumference of the drum

circumference of the drum = 2 $\pi$ r

where r is the radius.

So that;

circumference of the drum = 2 x $\frac{22}{7}$ x 4

= $\frac{176}{7}$

= 25.143

circumference of the drum = 25.143 feet

The linear velocity of the cable = (13 x 25.143) feet per minute

= 326.859 feet per minute

The linear velocity of the cable ≅ 327 feet per minute.
