32*12.5 = $400

Answer:

$25= (5)1.50 + 5x

Step-by-step explanation:

The answer is

$25= (5)1.50 + 5x

$25= 7.5 + 5x

$17.5= 5x

∆ABC=∆DEF

AB=DE –>String

BC=EF–> Rib

m<C=m<F=90° –>List

AC=DF

So m<A=m<D=35 (It is not clear whether the number is 35 or 36, but the same number)

Answer:

132

Step-by-step explanation:

The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180

This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180

So x = 180 - 48

180 - 48 = 132

Hence, x = 132

Answer:

14 mL

Step-by-step explanation:

because 1 ml = 25 mg we just need to divide 350 mg by 25 mg to know how many mL are equivalent to 350 mg.

350/25 = 14

therefore 14mL is equivalent to the 350 mg of the drug.

Hence,  the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.

What is an equation?

The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

Here,

[tex]1ml=25mg[/tex], here we need to divide [tex]350mg[/tex] by [tex]25 mg[/tex]  to know how many [tex]ml[/tex]are equivalent to [tex]350 mg.[/tex]

i.e., [tex]\frac{350}{25}=14[/tex]

Therefore, 14mL is equivalent to the [tex]350[/tex] mg of the drug.

Hence,  the liquid will need to be given is [tex]14ml[/tex] which is equivalent to the [tex]350[/tex] mg of the drug.

The system of equations has infinite solutions.

Option D is correct.

Matrix multiplication is a binary operation whose output is also a matrix when two matrices are multiplied.

To multiply one matrix with another, we need to check first, if the number of columns of the first matrix is equal to the number of rows of the second matrix. Now multiply each element of the column of the first matrix with each element of rows of the second matrix and add them all.

Given

Matrix equations

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

L.H.S:

Using Matrix multiplication

[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right][/tex]

R.H.S:

[tex]\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

[tex]\left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right]=\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]

Writing equation from above matrix

2x + 4y = 6

x + 2y = 3

or

2x + 4y = 6

2x + 4y = 6

Because there are two unknown number, but the two equations are consistent.

So, the system of equations has infinite solutions.

Option D is correct.

Answer:

See the detailed answers below

Step-by-step explanation:

Given data

Ratio=  1:4:7

combined ratio= 1+4+7= 12

Total amount= $636,000

Apply the part to all method

The first person will take

1/12= x/ 636,000

cross multiply

12x= 636,000*1

x= 636,000/12

x= 53000

The second person will take

4/12= x/ 636,000

cross multiply

12x= 636,000*4

x= 2544000/12

x= 212000

The third person will take

7/12= x/ 636,000

cross multiply

12x= 636,000*7

x= 4452000/12

x= 371000

Answer:

1: 130

2: 70

Step-by-step explanation:

Supplementary angles add up to equal 180

So to find the measure of the missing angles, we subtract the measure of the known angles from 180

For #1

∠B = 180 - 50

180 - 50 = 130

Hence ∠B = 130

For#2

∠D = 180 - 110

180 - 110 = 70  

Hence, ∠D = 70

Answer:

480

Step-by-step explanation:

The dice landed on two odds 12 out of the 50 times. Which is 24% of the time (.24). You then do 2,000 times 24% and get your answer of 480.

Answer:

80

Explanation:

Since it rises at a rate of 40 feet per minute, just multiply 40 times 6 to get 240. Then subtract 320 minus 240 to get 80
