$\sf \frac{225}{23} (488)-236b = 4428 \\ \\ \frac{109800}{23} + - 236b = 4428 \\ \\ -236b + \frac{109800}{23} = 4428 \\ \\ -236+ \frac{109800}{23} - \frac{109800}{23} = 4428 - \frac{109800}{23} \\ \\ -236b = \frac{-7956}{23} \\ \\ \boxed{{{\huge{{\bold{b = \dfrac{1989}{1357} }}}}}}$

Solution

1 Simplify $\frac{225}{23}$ ×488 to $\frac{109800}{23}$ 
 $\frac{109800}{23}$ −236b=4428

Subtract $\frac{109800}{23}$ from both sides
−236b=4428− $\frac{109800}{23}$

Simplify 4428− $\frac{109800}{23}$ to − $\frac{7956}{23}$
−236b=− $\frac{7956}{23}$

Divide both sides by −236
b= - $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ / 236

Simplify $\frac{7956}{23}$ to b= $\frac{7956}{23}$ ×236

Simplify to $\frac{7956}{5428}$

Simplify $\frac{7956}{5428}$ to $\frac{1989}{1357}$

B = $\frac{1989}{1357}$

In an honors math class of 25 students, 15 are boys and 10 are girls. On the final exam, 6 boys and 3 girls received a grade of

postnew [5]

Answer:

Step-by-step explanation:

b=boy

a= a on the exam

b=15

b∩a=6

b'∩a=3

b'∪a'=?

b'∪a'= b'+a'-b'∩a'

a= b∩a+b'∩a (law of total probability) = 9

a'= 25-9 = 16

b'= 25-15= 10

16+10-7=19

19/25= .76

Find the length of l on the curve r(t)=5cos(3t)i-5sin(3t)j+3tk over the interval [3,7]

stealth61 [152]

$\mathbf r(t)=5\cos3t\,\mathbf i-5\sin3t\,\mathbf j+3t\,\mathbf k$
$\mathrm d\mathbf r(t)=\mathbf r'(t)\,\mathrm dt=(-15\sin3t\,\mathbf i-15\cos3t\,\mathbf j+3\,\mathbf k)\,\mathrm dt$

$\displaystyle\int_C\mathrm d\mathbf r(t)=\int_{t=3}^{t=7}\|\mathbf r'(t)\,\mathrm dt\|=\int_{t=3}^{t=7}\sqrt{225\sin^23t+225\cos^23t+9}\,\mathrm dt$
$=\displaystyle3\sqrt{26}\int_{t=3}^{t=7}\mathrm dt$
$=12\sqrt{26}$

?/0.6=1.4 how to show the solution

den301095 [7]

To find the solution to this problem, you would do the opposite of division which is multiplication.

Use the terms you have to plug into your new equation;

0.6 x 1.4 = .84

To check your work you would plug in .84 where the '?' is;

.84/.6= 1.4

There you have the original equation you began with.

Therefore, .84 would be your final answer.

If the simple interest on $3,000 for 8 years is $1,680, then what is the interest rate?

madam [21]

We need to use the formula for simple interest which is
I= prt
Where I is the amount of money you earned or pay in interest
p is the principal, the amount you deposited or borrowed
r is the interest rate expressed as a decimal
t is time in terms of years

In this problem, I= 1,680
p= 3000
t= 8
'. r is what we are looking for.

Substituting the numbers into the simple interest formula, we get
I=. p r t
1,680=(3000)(r)(8). Multiplying
1,680= 24,000r Divide both sides by 24,000
0.07= r
So, the percentage is (0.07)(100)= 7%...
