Answer:

b=8

Step-by-step explanation:

Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.

we are given the line y=-3x-5

we need to find the slope of the new line. To do that, we can use this equation:

-3m=-1

divide by -3 on both sides

m=1/3

so the slope of the perpendicular line is 1/3

We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need

so far our equation is:

y=1/3x+b

we need to find b

we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b

so:

7=1/3(-3)+b

7=-1+b

8=b

so the y intercept of the line is 8; as a point it's (0,8)

hope this helps!

Answer:

120 ohms

Step-by-step explanation:

Given data

Voltage= 60 volts

Current= 0.5 amps

Power of bulb= 60 watt

We know that from Ohms law

V= IR

Make R subject of the formula

R= V/I

R= 60/0.5

R= 120 ohms

Hence the resistance is 120ohms

Answer:

A Bill le pagan $14 cada hora.

Step-by-step explanation:

Para conocer la cantidad que a Bill le pagan cada hora, se define una ecuación.

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos. Es decir, una ecuación se define como una igualdad establecida entre dos expresiones, en la cual puede haber una o más incógnitas que deben ser resueltas.

En este caso, es conveniente definir la siguiente incógnita:

Si cada hora que trabaja Bill aparta $6 para dárselos a su mamá, entonces cada hora recibirá: x - 6

Bill trabaja 3 horas al día, por lo que en ese día recibirá 3horas*(x-6). Y si la cantidad total con que se queda cada día es $24, entonces la ecuación a resolver será:

3*(x -6)= 24

Resolviendo, obtienes:

3*x - 3*6= 24

3*x - 18= 24

3*x= 24 +18

3*x= 42

x= 42÷ 3

x= 14

Entonces, a Bill le pagan $14 cada hora.

Answer:

AC = 12

Step-by-step explanation:

From the question, we have that BD is perpendicular to AC

This means that it is at 90 degrees to the base

so we have two similar right triangles

Let us use Pythagoras’ theorem to get the measure of one of the legs (AD and DC)

Let us call the leg x

We have the Pythagoras’ theorem stating that the square of the hypotenuse (the side facing the right angle; 10 here) is equal to the sum of the squares of the two other sides

10^2 = x^2 + 8^2

100 = x^2 + 64

x^2 = 100-64

x^2 = 36

x = √36

x = 6

AD = DC = 6

AC = 2 * AD

AC = 2 * 6

AC = 12

Answer:

a₅₇ = 214

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₅ = 6 and a₉₂ = 354 , then

a₁ + 4d = 6 → (1)

a₁ + 91d = 354 → (2)

Subtract (1) from (2) term by term to eliminate a₁

0 + 87d = 348

87d = 348 ( divide both sides by 87 )

d = 4

Substitute d = 4 in (1) and solve for a₁

a₁ + 4(4) = 6

a₁ + 16 = 6 ( subtract 16 from both sides )

a₁ = - 10

Then

a₅₇ = - 10 + (56 × 4 ) = - 10 + 224 = 214

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches

Answer:

80m²

Step-by-step explanation:

area of rectangle-&10m×6m=60m²

10m-6m=4m

10m×4m=40m²

area of triangle->40m²÷2=20m²

area->60m²+20m²=80m²

Step-by-step explanation:

Assuming the speed of car B to be x and the speed of car A to be x+20

156 = 208

x. x+20

156(x+20)= 208x

156x+3120=208x

3120=208x-156x

3120=52x

x=60

The speed of car A is (x)= 60

The speed of car B is(x+20)= 80

Answer:

[tex]\huge\colorbox{red}{Car\: A=80}\colorbox{blue}{Car B=60}[/tex]

Step-by-step explanation:

let the speed of car A be A

let the speed of car B be B

according to the first condition:

[tex]\quad A=B+20[/tex]

according to the second condition:

[tex]\quad 156(A)=208B[/tex]

therefore

[tex]\text{the speed of car A is 60+20=80}[/tex]

Well-designed child care centers typically have approximately 100 square feet per child of space in the overall center. So for example, a center proposing to serve 80 children would be likely to need a building that has about 8,000 square feet of total space available.

Answer:

x=28

Step-by-step explanation:

Sum of all the angles in the triangle add up to equal 180

90 + x + 6 + 2x = 180

combine like terns

96 + 3x = 180

subtract 96 from each side

180-96=84

96-96 cancels out

3x=84

divide each side by 3

84/3=28

3/3 cancels out

x=28

=========================================

Explanation:

The quadrilateral shown is a kite since we have adjacent sides that are the same length (due to the similar tickmarks). The diagonals of any kite intersect to form a 90 degree angle.

The triangle in the lower left corner has the three angles of

Those three interior angles must add to 180. This is true of any triangle.

90+(x+6)+(2x) = 180

3x+96 = 180

3x = 180-96

3x = 84

x = 84/3

x = 28

Answer:

So the answer is 2^-3

Step-by-step explanation:

The principle is the same no matter what the base.

Log_2 (7) + Log_2(3/28) - Log_2(6)

+ means multiply

- means divide

Log_2(7 * 3/28 /6)

Log_2(7/6 * 3/28)

Log_2(1/2 * 1/4)              3 divides into 6 twice. 7 divides into 28 four times

log_2 (1/8)

This is equivalent to 2^(-3)

Answer:

70

Step-by-step explanation:

since you are solving for the middle angle, you solve for the average for both angles on the side

(112+28)/2=70

x=70

Answer:

4

Step-by-step explanation:

Multiply 4/3 to both sides to cancel out the 3/4 on the left.

Next, subtract 8 from both sides to cancel out the 8 on the left.

This should result in the equation x = 4!

Answer:

x = 4

Step-by-step explanation:

3/4 times x = 3/4x

3/4 times 8 = 6

9 - 6 = 3

3 / (3/4) = 4
