Answer:

x = 25

Step-by-step explanation:

The two angles form a straight line which is 180 degrees

2x+10 + 4x+20 = 180

Combine like terms

6x+30 = 180

Subtract 30 from each side

6x+30-30 = 180-30

6x = 150

Divide by 6

6x/6 = 150/6

x=25

Answer:

  a) see attached

  b) 1/3

Step-by-step explanation:

Your grid doesn't come with any coordinate axes, so you will need to draw those and label them. You will also need to determine the number of grid squares for each unit. (I suggest 2 grid squares per unit to give you a little more distance between the points you plot. The attachment shows 5 small squares per unit. You may not have this much space on your graph.)

Plot the points. Once you do this, you can see that their horizontal difference is 3 units and their vertical difference is 1 unit. The right point is above the left point, so the slope is positive:

  m = (rise)/(run) = 1/3 . . . slope of the line

Answer:

30°

Step-by-step explanation:

because the sum of all interior angles in a triangle is 180 degrees

180°= ∡ADE+∡DAE+∡AED

∡ADE = 180°-∡DAE -∡AED

because the diagonals are perpendicular so they form 90° angles, and ∡BRC≅∡AED(vertical angles)

∡AED =90

To find ∡DAE we need to find the value of y

11y+2  =90

11y =90-2

y=88/11

y=8

∡DAE=7y+4=7 ·8 +4= 56+4 =60°

now we know what we need to find ∡ADE

∡ADE = 180°-∡DAE -∡AED

∡ADE = 180°-60° -90°

∡ADE = 30°

Answer:24.5

Step-by-step explanation:30% of 35 is 10.5.  To find the 30% off- you multiply 35 times 0.3 which is 10.5.  Then you subtract the 10.5 from 35 for the total cost.  35-10.5=24.50

Answer:

the answer is 24.5

First you multiply 35 x 0.3 = 10.5, then subtract 10.5, 35-10= 24.5

Which in total the answer is 24.5

Answer:

[tex]A = 43.0^o[/tex]

[tex]B = 55.0^o[/tex]

[tex]BC = 20.0[/tex]

Step-by-step explanation:

I will solve this question with the attached triangle

From the attachment, we have:

[tex]\angle C =82^o[/tex]

[tex]AB = 29[/tex]

[tex]AC = 24[/tex]

Required

Solve the triangle

First, we calculate [tex]\angle B[/tex] using sine law:

[tex]\frac{AC}{\sin(B)} = \frac{AB}{\sin(C)}[/tex]

This gives:

[tex]\frac{24}{\sin(B)} = \frac{29}{\sin(82^o)}[/tex]

[tex]\frac{24}{\sin(B)} = \frac{29}{0.9903}[/tex]

Cross multiply

[tex]\sin(B) * 29 = 24 * 0.9903[/tex]

[tex]\sin(B) * 29 = 23.7672[/tex]

Divide both sides by 29

[tex]\sin(B) = 0.8196[/tex]

Take arcsin of both sides

[tex]B = \sin^{-1}(0.8196)[/tex]

[tex]B = 55.0^o[/tex]

Next, calculate [tex]\angle A[/tex] using:

[tex]A + B + C = 180^o[/tex] --- angles in a triangle

[tex]A + 55^o + 82^o = 180^o[/tex]

Collect like terms

[tex]A = 180^o-55.0^o - 82^o[/tex]

[tex]A = 43.0^o[/tex]

Next, calculate BC using sine laws

[tex]\frac{BC}{\sin(A)} = \frac{AB}{\sin(C)}[/tex]

This gives:

[tex]\frac{BC}{\sin(43.0)} = \frac{29}{\sin(82)}[/tex]

[tex]\frac{BC}{0.6820} = \frac{29}{0.9903}[/tex]

Make BC the subject

[tex]BC = \frac{29*0.6820}{0.9903}[/tex]

[tex]BC = 20.0[/tex]

∠ BOC = 40°

Step-by-step explanation:

∠ AOC = 90° , then

5x + 2x + 20 = 90

7x + 20 = 90 ( subtract 20 from both sides )

7x = 70 ( divide both sides by 7 )

x = 10

Then

∠ BOC = 2x + 20 = 2(10) + 20 = 20 + 20 = 40°

By using substitution method, the number of nickels is 8 and the number of dimes is 13.

The substitution method is one of the algebraic methods to solve simultaneous linear equations. It involves substituting the value of any one of the variables from one equation into the other equation.

Representing the nickels as n and the dimes as d, and knowing that a nickel is 5 cents and a dime is 10 cents, we can write two equations from the given data.

n + d = 21

5n + 10d = 170

We use the first equation to derive a value for n.

n + d = 21

Subtract d from each side.

n + d - d = 21 - d

n = 21 - d.........................(1)

We now simplify the second equation by dividing all terms by 5.

5n + 10d = 170

[tex]\frac{5n}{5} +\frac{10d}{5} =\frac{170}{5}[/tex]

n + 2d = 24

substitute n = 21 - d in above equation

(21 - d) + 2d = 24

21 -d +2d = 24

21 + d = 24

d = 24 - 21

d = 13

n = 21 - d

n = 21 - 13

n = 8

Thus, the number of nickels is 8 and the number of dimes is 13.

Explicação passo a passo:

Deixar :

Largura = x

Comprimento = 5x

Perímetro = 180

Já o terreno tem uma forma retangular; usamos a relação;

Perímetro = 2 (comprimento + largura)

180 = 2 (5x + x)

180 = 2 (6x)

180 = 12x

180/12 = x

15 = x

Largura = x = 15 metros

Comprimento = 5x = 15 * 5 = 75 metros

Step-by-step explanation:

Distributive property in mathematics means to multiply the sum by a number of two or more add-ons will provide the same result that each add-on multiplies by a single number and then together add the products.

for example a( b+c) = ab+ac

Therefore, applying distributive property in asked eapression

12(2a - 6b+ 8) = 21(2a−6b+8)

24a+72b+96 = 42a-126b+168

198b=18a+72

9a +36=99b

3a+12=33b

The law of sines is based on the proportionality of sides and angles in triangles. The law states that for the angles of a non-right triangle, each angle of the triangle has the same ratio of angle measure to sine value.

sin(A)/a=sin(B)/b=sin(C)/c

Substitute the known values into the law of sines to find a.

sin(60)/a=sin(60)/2

I don't know

Given:

In circle F, [tex]m\angle EFG=122^\circ,\ EF=16[/tex] units.

To find:

The length of arc EG.

Solution:

It is given that, [tex]m\angle EFG=122^\circ,\ EF=16[/tex] units. It means the central angle of arc EG is 122 degrees and the radius of the circle F is 16 units.

Formula for arc length is:

[tex]s=2\pi r\times \dfrac{\theta}{360^\circ }[/tex]

Where, r is the radius and [tex]\theta [/tex] is the central angle in degrees.

Putting [tex]r=16,\ \theta=122^\circ,\ \pi=3.14[/tex], we get

[tex]s=2(3.14)(16)\times \dfrac{122^\circ}{360^\circ }[/tex]

[tex]s=100.48\times \dfrac{61}{180}[/tex]

[tex]s=34.0515556[/tex]

[tex]s\approx 34.05[/tex]

Therefore, the length of arc EG is 34.05 units.

Step-by-step explanation:

Logarithmic functions are the inverses of exponential functions. Hence, exponential functions can be expressed in logarithmic form whereas logarithmic function can be expressed in exponential form. Since log is a function, it is most correctly written as log.

Given that f(x) = log₁₀(x)

To find the value of f(50), we substitute x to be 50 in the logarithm function and solve:

f(50) = log₁₀(50)

f(50) = log₁₀(5 * 10) = log₁₀(5) + log₁₀(10)  

f(50) = 1 + log₁₀(5) = 1 + 0.70

f(50) = 1.70

1) if he wants to do that he needs 0.6 gallons x 14 days = 8,4 gallons.

If the car starts with 14 gallons then he is able to ride 14 days without the warning light.

2) now he would need 0.6 gallons x 25 days = 15 gallons.

he only has 14 gallons so that is not possible.

3) no clue sorry

4) x= the days he can drive without the warning light

14-1,5 = 0,6.x

<=>12,5= 0,6.x

<=>20,833... = x

He can go 20 days without the warning light.

5) x= the days he can drive his car without seeing the warning light.

x.0,6<12,5

<=> x<20,833...

If he drives 20,833... days he will see the warning light so everything before that he won't see it.

Answer:

(a) The ball will hit the ground after 3 seconds

(b) The maximum height is 6.125

Step-by-step explanation:

Given

[tex]h(t) = -2t^2 +5t +3[/tex]

Solving (a): When the frisbee will hit the ground?

To do this, we set h(t) to 0

So, we have:

[tex]h(t) = -2t^2 +5t +3[/tex]

[tex]-2t^2 +5t +3=0[/tex]

Expand

[tex]-2t^2 +6t-t +3=0[/tex]

Factorize

[tex]-2t(t - 3) -1(t - 3) = 0[/tex]

Factor out t - 3

[tex](-2t -1)(t - 3) = 0[/tex]

Split:

[tex]-2t -1= 0\ or\ t - 3 = 0[/tex]

Solve for t in both equations

[tex]-2t =1\ or\ t = 3[/tex]

[tex]t =-\frac{1}{2}\ or\ t = 3[/tex]

Time can't be negative; So:

[tex]t = 3[/tex]

Solving (b): How height the frisbee will go?

First, we calculate time to reach the maximum height

[tex]t = -\frac{b}{2a}[/tex]

Where:

[tex]h(t) = at^2 + bt + c[/tex]

By comparison:

[tex]a = -2,\ b =5,\ c =3[/tex]

So:

[tex]t = -\frac{b}{2a}[/tex]

[tex]t = -\frac{5}{2*-2}[/tex]

[tex]t = \frac{5}{4}[/tex]

[tex]t = 1.25[/tex]

So, the maximum height is:

[tex]h_{max} = -2 * 1.25^2 + 5 * 1.25 + 3[/tex]

[tex]h_{max} = 6.125[/tex]
