What is the measure of angle TSU?
Irina-Kira [14]

Answer:

m<TSU = 65

Step-by-step explanation:

As one can see, the measure of angle (RST) is (90) degrees. This is indicated by the box around the angle. As a general rule, when there is a box around an angle, the angle measure if (90) degrees. It is also given that the measure of angle (RSU) is (25) degrees. As per the given diagram, the sum of the measures of angles (RSU) and (UST) is (RST). Therefore, one can form an equation and solve for the measure of angle (UST).

(RSU) + (UST) + (RST)

Substitute,

25 + (UST) = 90

Inverse operations,

25 + (UST) = 90

UST = 65

(<UST) is another way of naming angle (TSU).

Sara bought a 16-ounce jar of strawberry jam for $3.20 What is the unit price?
wolverine [178]

Answer:

$0.20

Step-by-step explanation:

so you have 16 ounces of jam. i personally like jelly, but that's besides the point lol

so for those 16 ounces, you paid $3.20 for them.

unit price is just a term for the price of 1 item or measurement. you can use this to find out what product you are purchasing has the better deal, because you always want more product, for less money.

you should take the amount of money you are spending, and divide it by how many total ounces it has.

$3.20 / 16 = 0.20

this means that 1 ounce of jam costs $0.20

you can check your work by multiplying the price of one ounce, by how many ounces the jar is.

.2 * 16 = 3.20

i hope this was helpful to you and i explained well enough!

stay safe!!
