Answer:7.5
Step-by-step explanation:
Answer:
A. 2.1 fluid ounces
Step-by-step explanation:
Following information given in the statement
8 ounce milk=270.0 mg calcium
we have to find how many ounce of milk=72.5 mg calcium
Let x be the amount of milk possess 72.5 milligrams of calcium.
So, x=(72.5*8)/270
x=580/270=2.148
Rounding x to nearest tenth
x=2.1
Hence, 2.1 ounce milk contains 72.5 mg calcium.
Answer:
1/6
Step-by-step explanation:
the form you're using is slope-intercept. That is
y=mx+b
where y= y coordinate
m=slope
x= x coordinate
and b= y intercept
so, m in that equation is 1/6, so the slope is 1/6
Hope this helps!
Ok for 22 you just have to add both of them together and set them to equal 90. ( 4z+ 3z+6=90). then you solve for z by combining like terms giving you 7z+6=90 then subtract 6from both side leaving you with 7z=84. then divide to get z=12. you thin plug 12 into the angles such as 4(12) and 3(12)+6 which give you 48 and 42 degrees and to double check just add your 2 degrees together to form 90.
on problem 20, add both angles together and set to 180 (4h+5+8h-5=180) since the line is like half a circle. then combine like terms (12h=180) divide by 12 and then after dividing 180 by 12 and getting 15 you substitute 15 in for h.
