which of these is right

Answer:

The area is 7.5 square units

Answer:

∠ LMN = 65° , ∠ PQR = 25°

Step-by-step explanation:

Complementary angles sum to 90°

∠ LMN + ∠ PQR = 90° , that is

8x + 1 + 2x + 9 = 90

10x + 10 = 90 ( subtract 10 from both sides )

10x = 80 ( divide both sides by 10 )

x = 8

Then

∠ LMN = 8x + 1 = 8(8) + 1 = 64 + 1 = 65°

∠ PQR = 2x + 9 = 2(8) + 9 = 16 + 9 = 25°

Answer:

5^6

Step-by-step explanation:

This is because the exponent is how many numbers are in the multiplication equation, in this case, five. Because there are six five's being multiplied together, our exponent is six.

The total distance of the race is D = 96 miles

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let's denote the total distance of the race as "d" miles.

According to the given information, Mark ran half the distance and swam a quarter of the distance. This can be expressed as:

Distance Mark ran = d/2 miles

Distance Mark swam = d/4 miles

After Mark's quick break, he was just starting to bike the remaining 24 miles. Since he has already completed running and swimming, the total distance he has covered at that point is:

And this distance is equal to 24 miles, as given in the problem:

d/2 + d/4 + 24 = d

On simplifying the equation , we get

( 3/4 )d + 24 = d

Subtracting ( 3/4 )d on both sides , we get

( 1/4 )d = 24

Multiply by 4 on both sides , we get

d = 96 miles

Hence , the total distance of the race, denoted by "d", is 96 miles

Answer:

  56th batch

Step-by-step explanation:

The least common multiple of 8 and 28 is 8·7 = 56. Tom and Larry will both test the 56th batch.

__

There are a couple of ways to find the least common multiple (LCM) of a pair of numbers.

1. Factor them and use the highest power of the unique factors.

  8 = 2³

  28 = 2²×7

Unique factors are 2 and 7. Their highest powers are 3 and 1, so the LCM is ...

  (2³)(7) = 56

__

2. Divide the product by the greatest common divisor (GCD). Here, both numbers are divisible by 4:

  8 = 4·2

  28 = 4·7

So, the LCM is 8×28/4 = 56.

Answer:

Step-by-step explanation:

8=2x2x2

28=2x2x7

lcm of 8,28= 56

Answer:

36

Step-by-step explanation:

Replace the 2b with 10 and then do the parenthesis, so 10-4=6

now multiply it with the 6 outside the parenthesis and you get 36

Hi! I'm happy to help!

First of all, we need to substitute b into the expression.

6(2b-4)

6((2×5)-4)

Now we use the order of operations, or PEMDAS (Parenthesis, Exponents, Multiplication or Division, and Addition or Subtraction) to finish simplifying.

We see that 2×5 is inside two sets of parenthesis, so we solve that first

6((2×5)-4)

6((10)-4)

We cam remove the extra set of parenthesis because there isn't an expression inside of it any more.

6(10-4)

Now, we look inside of the parenthesis again and we see 10-4

6(10-4)

6(6)

The six next to the parenthesis has no sign next to it, which means to multiply.

6×(6)

Now we can remove the parenthesis.

6×6

Now, we just simply multiply.

6×6

36

To sum it up: The value of 6 (2b-4) When b=5 is 36

94-100=6

So I'm just gonna assume that 6% of people prefer to watch soccer.

Now to solve how many people out of 1000 would watch soccer we'd have to multiply 1000 by 0.09 which gives us 90.

So 90 people out of 1000 would prefer to watch soccer.

b=130

c=130

Step-by-step explanation:

2a-50=a(vertically opposite angles)

a=50

a+c=180(angles on straight line)

50+c=180

c=180-50=130

b=c(vertically opposite angles)

b=130

Answer:

see below

Step-by-step explanation:

Part A

We can shift f(x) to the left or shift it up

Part B

f(x+k) for a shift to the left

f(x) + k for a shift up

Part C

Looking at shifting f(x) to g(x) by going left, we are shifting 6 units to the left

f(x+6) will shift f(x) 6 units to the left

g(x) = f(x+6)

We can all shift f(x) up, we can shift up 18 units

f(x) +18 will shift the function up 18 units

g(x) = f(x) +18

The value of s=10

Step-by-step explanation:

11+(-1)=10

Answer:

For parallel:

gradient is 1/5

[tex]y = mx + c[/tex]

consider (5, -2):

[tex] - 2 = ( \frac{1}{5} \times 5) + c \\ - 2 = 1 + c \\ c = - 3[/tex]

[tex]{ \boxed{ \bf{equation : y = \frac{1}{5}x - 3 }}}[/tex]

For perpendicular:

gradient, m1:

[tex]m _{1} \times m_{2} = - 1 \\ m _{1} \times \frac{1}{5} = - 1 \\ \\ m _{1} = - 5[/tex]

gradient = -5

[tex]y = mx + c \\ - 2 = (5 \times - 5) + c \\ - 2 = - 25 + c \\ c = 23[/tex]

[tex]{ \boxed{ \bf{equation :y = - 5x + 23 }}}[/tex]

Answer:

Parallel: [tex]y=\displaystyle \frac{1}{5}x-3[/tex]

Perpendicular: [tex]y=-5x+23[/tex]

Step-by-step explanation:

Hi there!

What we must know:

Finding the Parallel Line

[tex]y=\displaystyle \frac{1}{5} x-3[/tex]

Given this equation, we can identify that its slope (m) is [tex]\displaystyle \frac{1}{5}[/tex]. Because parallel lines always have the same slope, the slope of the line we're currently solving for would be [tex]\displaystyle \frac{1}{5}[/tex] as well. Plug this into [tex]y=mx+b[/tex]:

[tex]y=\displaystyle \frac{1}{5}x+b[/tex]

Now, to find the y-intercept, plug in the given point (5,-2) and solve for b:

[tex]-2=\displaystyle \frac{1}{5}(5)+b\\\\-2=1+b\\-2-1=b\\-3=b[/tex]

Therefore, the y-intercept is -3. Plug this back into [tex]y=\displaystyle \frac{1}{5}x+b[/tex]:

[tex]y=\displaystyle \frac{1}{5}x+(-3)\\\\y=\displaystyle \frac{1}{5}x-3[/tex]

Our final equation is [tex]y=\displaystyle \frac{1}{5}x-3[/tex].

Finding the Perpendicular Line

[tex]y=\displaystyle \frac{1}{5} x-3[/tex]

Again, the slope of this line is [tex]\displaystyle \frac{1}{5}[/tex]. The slopes of perpendicular lines are negative reciprocals, so the slope of the line we're solving for would be -5. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-5x+b[/tex]

To find the y-intercept, plug in the point (5,-2) and solve for b:

[tex]-2=-5(5)+b\\-2=-25+b\\-2+25=b\\23=b[/tex]

Therefore, the y-intercept is 23. Plug this back into [tex]y=-5x+b[/tex]:

[tex]y=-5x+23[/tex]

Our final equation is [tex]y=-5x+23[/tex].

for the volume of a box all three dimensions must be multiplied with each other to create a cubic result.

3x²y × 4y²z × 5z²x

we need to combine the elements belonging to each other = that can be combined for simplification :

the constants, the x, the y and the z.

3×4×5 = 60

x²×x = x³

y×y² = y³

z×z² = z³

so, in total, that multiplication result is

60x³y³z³

therefore, (c) is the right answer
