Hello,
Let's f the age of the father
s the age of Simran
f=3*s
f-5=4*(s-5)
==>3s-5=4s-20
==>s=15
f=3*15=45
Refer to the diagram shown below.
Given:
m∠A = 19°
c = 15
By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835
cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828
Answer:
The lengths are 4.88, 14.18, and 15.00 (nearest hundredth)
$2.10 - $2 = $0.10
The banana cost 10 cents.
Hi there!
Since we know that the pancake mix has 5% of the daily allowance, which is 300 mg, we can just multiply 300 mg with 5 percent to get our answer.
First, let's divide 5% by 100% to know what we are going to multiply 300 mg with.
5% / 100% = 0.05
Let's multiply 300 mg with 0.05
0.05 * 300 = 15 mg
Thus, a 1/2 cup of pancake mix has 15 mg of cholesterol.
Have an awesome day! :)
Answer:
Step-by-step explanation:
given are four statements and we have to find whether true or false.
.1 If two matrices are equivalent, then one can be transformed into the other with a sequence of elementary row operations.
True
2.Different sequences of row operations can lead to different echelon forms for the same matrix.
True in whatever way we do the reduced form would be equivalent matrices
3.Different sequences of row operations can lead to different reduced echelon forms for the same matrix.
False the resulting matrices would be equivalent.
4.If a linear system has four equations and seven variables, then it must have infinitely many solutions.
True, because variables are more than equations. So parametric solutions infinite only is possible
