Answer:
8.45 grams
Step-by-step explanation:
In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?
1 mg = 0.001 g
8450 mg = x
Cross Multiply
= 8450 × 0.001 g
= 8.45 g
Therefore, Shelly should enter 8.45 grams

Answer:
Step-by-step explanation:
Solve 2x−9y=14;−5x+9y=−8
Steps:
I will solve your system by substitution.
(You can also solve this system by elimination.)
2x−9y=14;−5x+9y=−8
Step: Solve2x−9y=14for x:
2x−9y+9y=14+9y(Add 9y to both sides)
2x=9y+14

30-7x4 = 2
3.
80
Step-by-step explanation:
2.
First, do 7x4, which equals 28. Then subtract that from 30, and you get 2.
3.
Do the parentheses first, 21-6=15. Then 15 divided by 0.2 = 75. 75+5=80.

Answer:
Step-by-step explanation:
Let the relation between the total number of candies (y) and number of bags (x) is,
y = mx + b
Here, b = Extra pieces of candies sitting outside the box.
m = Candies per box
From the question,
x = 4,(Number of bags are 4)
y = 4m + 4
If total number of candies are 36,
36 = 4m + 4
4m = 32
m = 8
Each bag will contain 8 candies.
Therefore, equation representing the relation is,
y = 8x + 4
Now complete the table by substituting the values of x,

divide through by 5
5x÷5 = 65÷5
x= 13
Find the area of the triangle shown above
Answer:
the area is 32 square inches
Step-by-step explanation:
you multiply both sides that have 9 because they are equal and then you add the 14 on
Answer:
63 Inches
Step-by-step explanation:
The formula for finding the area of a triangle is:
(b*h)/2
First, let's plug in the values.
(14*9)/2
Simplify...
126/2
Divide the two which gives us:
63
Therefore, the answer is:
63 Inches.

Answer:
2000 feet.
Step-by-step explanation:
Let the length of fence need be x feet.
Then we have the equation:
2lx = 19x + 4000
21x - 19x = 4000
2x = 4000
x = 2000.
Solve the system of equations by substitution. * -8x + 2y = 4 y = 4x + 2
Answer:
Step-by-step explanation:
-8x + 2y = 4
y = 4x + 2
Put the value of y into the first equation
-8x + 2(4x + 2) = 4 Remove the brackets
-8x + 8x + 4 = 4 The 8xs cancel out.
4 = 4 But this is useless. There is no single solution

If y varies directly with x. and y=10 when x=5.6, find the value of y when
X=3
Answer: 5.3571
Step-by-step explanation:
The formula used to calculate direct proportion is: y = kx
We will find the constant of proportionality when y=10 and x=5.6. This will be:
y = kx
10 = 5.6k
k = 10/5.6
k = 1.7857143
The value of y when X=3 will be:
y = kx
y = 1.7857143 × 3
y = 5.3571

Which correlation coefficient would most likely show a weak negative association?
A: -0.07
B: -0.88
C: 0.09
D: 0.91
Answer:
Step-by-step explanation:
We can use the regression line to model the linear relationship between x and y ... x and y because the correlation coefficient is not significantly different from zero. ... If r is significant and the scatter plot shows a linear trend, the line can be used to ... If r < negative critical value or r > positive critical value, then r is significant.
