If you have 5000 per 125 mcg and need 7140 how many mcg do you need?
Answer:
178.5mcg
Step-by-step explanation:
If you need 5000 per 125mcg, we can express it as;
5000 = 125mcg
To get the amount of mcg needed for 7140, we will say;
7140 = x mcg
Divide both expression
5000/7140 = 125/x
Cross multiply
5000x x= 7140 * 125
5000x = 892,500
x = 892,500/5000
x = 178.5
Hence the amount og mcg needed is 178.5mcg

Step-by-step explanation:
The sum of all angles in a triangle is always 180.
So we can set up an equation
3/2x+1/2x+x= 180
3/2+1/2x+2/2x=180
3x+1x+2x=360
6x=360
x=60
plz answer!!! only if correct.
Answer:
90°Step-by-step explanation:
Sum of angles in triangle equals to 180°
∠R = 180° - (∠S + ∠T)∠R = 180° - (29° + 61°) = 180° - 90° = 90°modeled by the expression –2 • 4.

Larissa plans to bake at most 10 loaves of bread. She makes x loaves of banana bread that sell for $1.25 each and y loaves of nut bread that sell for $1.50 each. She hopes to make at least $24 in sales. Write and graph a system of inequalities for this situation. What does the graph show?
Answer:
1) The system of inequalities are;
x × 1.25 + y × 1.5 ≥ 24
x + y ≤ 10
Please find attached the required graph of the two inequalities ,created with Microsoft Excel
2) The graph of inequality shows that Larissa cannot to make less than 10 loafs of bread and sell them for over $24 at the given prices of each loaf of bread
Step-by-step explanation:
1) The maximum number of loaves Larissa plans to make = 10
The price at which she sells each of x loaves of banana bread = $1.25
The price at which she sells each of y loaves of nut bread = $1.50
The total amount she hopes to make = $24
The system of inequalities are;
x × 1.25 + y × 1.5 ≥ 24
x + y ≤ 10
Making y the subject of both inequalities gives;
For the first inequality, we have,
y ≥ 24/1.5 - 1.25/1.5·x which gives;
y ≥ 16 - 5/6·x
For the second inequality, we have,
y ≤ 10 - x
Please find attached the required graph of the two inequalities
2) From the attached graph of inequality, created with Microsoft Excel, it shows that it is not possible for Larissa to make less than 10 loafs of bread and at the same time sell them for over $24 if the price of each banana bread is $1.25 and the price of each nut bread is $1.50.
