I = [tex]\frac{V}{R}[/tex]

I is the current, V the voltage and R the resistance, thus

I = [tex]\frac{30}{3}[/tex] = 10

Answer:

x = - 8, x = 6

Step-by-step explanation:

Given

(x - 6)(x + 8) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 8 = 0 ⇒ x = - 8

Answer:

x =  -8, 6.

Step-by-step explanation:

(x– 6)(x + 8) = 0

Either factor can be zero:

x - 6 = 0 gives x = 6 and

x + 8 = 0 gives x = -8.

Answer:

8000

Step-by-step explanation:

|Thousands||Hundreds||Tens||Ones|

|       7          ||        7       ||   6  ||    6   |

5 or more, raise the score (turn the 7 into an 8 and make the three other numbers 0)

4 or less, let it rest (leave the 7 as a 7 and make the other 3 numbers 0).

The number that we are looking at changing will be bold. The number that determines if we change that number will be underlined.

7766

The 5 or more, raise the score rule applies to 7.

So, we will make the 7 thousand (7000) 8 thousand (8000)

We will make the seven hundred sixty six (766) zero (0).

Our final answer is 8000.

Answer:

[tex] \red {\frak{Given}} \begin{cases} & \sf{Two\ consecutive\ natural\ numbers.} \\ & \sf{The\ sum\ of\ the\ numbers\ is\ {\pmb{\sf{475}}}.} \end{cases}[/tex]

We know that,

Therefore,

[tex] \sf \dashrightarrow {x\ +\ x\ +\ 1\ =\ 475} \\ \\ \\ \sf \dashrightarrow {2x\ +\ 1\ =\ 475} \\ \\ \\ \sf \dashrightarrow {2x\ =\ 475\ -\ 1} \\ \\ \\ \sf \dashrightarrow {2x\ =\ 474} \\ \\ \\ \sf \dashrightarrow {x\ =\ \dfrac{\cancel{474}}{\cancel{2}}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{x\ =\ 237.}}}}_{\sf \blue {\tiny{First\ number}}}} [/tex]

∴ Hence, the first number is 237. Now, let us find out the second number.

[tex]\rule{200}{3}[/tex]

Second NumbeR :

∴ Hence, the second number is 238.

The two consecutive numbers whose sum is 475 are 237 and 238.

Let assume the two consecutive natural numbers as x and x+1.

According to the given information,

the sum of the two consecutive numbers is 475.

So, the equation can be set up as:

x + (x+1) = 475

Combining like terms, we get:

2x + 1 = 475

Subtracting 1 from both sides, we have:

2x + 1 - 1  = 475 - 1

2x = 474

Dividing both sides by 2, we find:

x = 237

Thus, the two consecutive numbers are 237 and 238.

Final answer:

To find 15% of 75% of 80, calculate 75% of 80 first (0.75  imes 80 = 60), then find 15% of 60 (0.15  imes 60 = 9), resulting in an answer of 9.

Explanation:

The student has asked: What is 15% of 75% of 80?

To solve this problem, we'll need to follow these steps:

First, find 75% of 80.

Then, find 15% of the result from step 1.

Let's start with the first step:

75% of 80 is equivalent to 0.75  imes 80, which equals 60.

Now, for the second step:

15% of 60 is equivalent to 0.15  imes 60, which equals 9.

Therefore, 15% of 75% of 80 is 9.

Answer:

69.1

Step-by-step explanation:

Mean height of 14 students = 69.0 inches

Mean = sum of data/number of data

69 = sum of data/14

sum of data = 966

FOR NEW MEAN:

Height of additional student = 70.5

Mean = sum of data/ number of data

Mean = 966+70.5/14+1

Mean = 1036.5/15

Mean = 69.1

Therefore, the mean height of the 15 students in the class is 69.1

Final answer:

To find the new mean height after Danielle joins the class, calculate the total height of all students, add Danielle's height, and divide by the new number of students. The mean height increases to 69.1 inches.

Explanation:

Mr. Zuro finds the mean height of all 14 students in his class to be 69.0 inches. When Danielle, who is 70.5 inches tall, walks in late, we need to calculate the new mean height of all 15 students.

First, we find the total height of the initial 14 students by multiplying the mean height by the number of students: 69.0 inches × 14 = 966 inches. Next, we add Danielle's height to this total: 966 inches + 70.5 inches = 1036.5 inches. Finally, to find the new mean height, we divide this total by the number of students, now 15: 1036.5 inches ÷ 15 = 69.1 inches.

Therefore, the mean height of the 15 students in the class, including Danielle, is now 69.1 inches.

Answer:

(n+3)/7

Step-by-step explanation:

Let

n -----> the unknown number

we know that

The algebraic expression of the phrase " the sum of a number and three" is equal to

(n+3) -----> number n plus number 3

so

The algebraic expression of the phrase " the sum of a number and three divided by seven" is equal to

(n+3)/7 ----> divide (n+3) by the number 7

therefore

The expression is

(n+3)/7

Answer:

Part 1) x=8

Part 2)  m∠RSU=133°

Part 3) m∠UST=47°

Part 4) m∠WSV=43°

Part 5) m∠VSU=137°

Step-by-step explanation:

see the attached figure to better understand the problem

Part 1) Find the value of x

we know that

m∠RSU and m∠UST are supplementary angles (by linear pair)

so

m∠RSU+m∠UST=180°

we have

m∠RSU=(17x-3)°

m∠UST=(6x-1)°

substitute the given values and solve for x

[tex](17x-3)\°+(6x-1)\°=180\°[/tex]

[tex](23x-4)=180[/tex]

[tex]23x=180+4[/tex]

[tex]23x=184[/tex]

[tex]x=8[/tex]

Part 2) Find the measure of m∠RSU

we have

m∠RSU=(17x-3)°

substitute the value of x

m∠RSU=17(8)-3=133°

Part 3) Find the measure of m∠UST

we have

m∠UST=(6x-1)°

substitute the value of x

m∠UST=6(8)-1=47°

Part 4) Find the measure of m∠WSV

we know that

m∠UST=m∠RSW -----> by vertical angles

so

m∠RSW=47°

m∠RSW+m∠WSV=90° ----> given problem (SV perpendicular RT)

substitute the value of m∠RSW and solve for m∠WSV

47°+m∠WSV=90°

m∠WSV=90°-47°=43°

Part 5) Find the measure of m∠VSU

we know that

m∠VSU=m∠VST+m∠UST

we have

m∠VST=90° ----> given problem (SV perpendicular RT)

m∠UST=47°

substitute

m∠VSU=90°+47°=137°

Answer:

y = - 6x - 19

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 6x - 4 ← is in slope- intercept form

with slope m = - 6

• Parallel lines have equal slopes, thus

y = - 6x + c ← is the partial equation

To find c substitute (- 3, - 1) into the partial equation

- 1 = 18 + c ⇒ c = - 1 - 18 = - 19

y = - 6x - 19 ← in slope- intercept form

Answer:

r = 7

Step-by-step explanation:

Use the distributive property by multipling the -8 to the 2r and the -8, do the same thing on the other side with the -3.

Afterwards, combine like terms by adding 64 and 6.

Next, add 3r to the left side, I usually choose the number with the variable (the letter) that looks like it will be easier to subtract. This leaves only 21 on the right side.

Next subtract 70 from both sides

Divide -13 by both sides
