A box contains 4 bags of sugar. The total mass of all 4 bags is 6 kg. What is the mass of each bag in grams?
Sergio [31]
Divide by 4 to get the mass of a single bag and then multiply by 1000 to get to grams from kilograms

6/4=1.5

1.5*1000=1500

therefore a single bag of sugar weighs 1500 grams

P Is inversely proportional to Q.
cluponka [151]
The proportion is 100:32.
You can put this into a fraction 100/32 and conclude that P is 3.3 repeating times larger than Q.
When Q=80, P will be 3.3 times larger than 80.
The answer is P = 266.6 repeating or 266.67.

3. A mysterious metal medallion has a mass of 3,088 grams. Water is poured into a graduated glass container with a 10-by-10 cm s
velikii [3]

Answer:

<u>Initial volume:</u>

  • 10*10*53 = 5300 cm³

<u>Increased volume:</u>

  • 10*10*54.6 = 5460 cm³

<u>Volume of the medallion:</u>

  • 5460 - 5300 = 160 cm³

Density = mass / volume

<u>Density is:</u>

  • 3.088/160 = 19.3 g / cm³

Which representation has a constant of variation of -2.5
Neporo4naja [7]

Answer:

See explanation

Step-by-step explanation:

The constant of variation is found using the slope formula:

\frac{y_2-y_1}{x_2-x_1}

The given relation is

X : -2 , -3, -4, -5  

Y : -5, -7.5,-10,-12.5

We can use any two ordered pair to find the constant of variation.

Using (-2,-5) and (-3,-7.5), we have

m=\frac{-7.5--5}{-3--2} =\frac{-2.5}{-1} =2.5

The constant of variation is 2.5

We need to repeat this for all the options to identify the one with -2.5 as slope.

unfortunately, you did not provide the remaining options.

Find the exact value of sec (theta) if cot (theta) = -2 and the terminal side of theta lies in quadrant IV.
zmey [24]
We know that
<span>sec (theta)=1/cos (theta)

</span><span>cot (theta) = -2
cot (theta)=cos (theta)/sin (theta)
</span>cos (theta)/sin (theta)=-2----> squaring-----> cos² (theta)/sin² (theta)=4
<span>remember that
sin</span>²(theta)+cos²(theta)=1
sin² (theta)=1-cos² (theta)
substitute
 cos² (theta)/[1-cos² (theta)]=4
cos² (theta)=4*[1-cos² (theta)]-----> cos² (theta)+4 cos² (theta)=4
5*cos² (theta)=4-----> cos² (theta)=4/5----> cos (theta)=2/√5
cos (theta)=(2√5)/5-----> is positive  (IV quadrant)
sec (theta)=1/cos (theta)----> √5/2

the answer is
sec (theta)=√5/2
