Find the measure of ∠3.




90°


130°


50°


40°

here,

a1=-1

a2=-1+4 =3

a3= 3+4=7

a4=7+4=11

using the general formula for nth term of an ap

[tex]an = - 1 + (n - 1)d \\ here \: a = - 1 \: and \: d = 4 \\ \\ an = - 1(n - 1)(4) = - 1 + 4 - 4 \\ 4n - 5 \\ \\ hence \: a25 = \\ 4(25) - 5 = 100 - 5 = 95[/tex]

Answer= a25 = 95

Answer:

Step-by-step explanation:

There are 2 x 3 x 3 = 18 combinations of coffee.  Only one is large, iced and

hazelnut

So, the probability is 1/18

Answer:

180 degrees

Step-by-step explanation:

East and west are two opposite directrions along the same line.

The angle is 180 degrees.

Answer: 180°

Step-by-step explanation: The directions on a compass would look something like this; (Refer to the image.)

A full circle is 360°. Half of 360 is 180. You would have to make a clockwise rotation by 180° to face West. Think of this picture as a clock or a circle.

I hope this helps!

Answer:

Cada garrafa tiene una capacidad de 24 litros.

Step-by-step explanation:

Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.

Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:

(20%/100%)*V

Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:

(30%/100%)*V

El volumen total de agua es la suma de esos dos volúmenes, que nos da:

(20%/100%)*V + (30%/100%)*V

Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:

12 L = (20%/100%)*V + (30%/100%)*V

Ahora podemos resolver esto para V.

12L = 0.2*V + 0.3*V

12L = 0.5*V

12L/0.5 = V

24L = V

Cada garrafa tiene una capacidad de 24 litros.

Answer:

Step-by-step explanation:

1. slope = 2, initial value = 5

equation :  y = 2x+5

2. slope: (3-6)/5 = -0.6; initial value = 6

equation : y = -0.6x+6

3. slope : (5- -1)/2 = 3; initial value = -1 -2*3 = -7

equation : y = 3x -7

4. Sorry, cannot see the last point.

Answer:

Hello! answer: c = 4

Step-by-step explanation:

triangle area formula: base × height ÷ 2 or base × height × 1/2

6 × 4 = 24

24 ÷ 2 = 12 therefore c = 4 Hope that helps!

Answer:

[tex]m\angle 1 = 40^\circ[/tex]

Step-by-step explanation:

First, notice that the two lines are parallel as indicated by the arrow.

Therefore, by the Alternate Interior Angles Theorem:

[tex]\angle 1\cong \angle 2[/tex]

So:

[tex]m\angle 1 = m\angle 2[/tex]

Substitute:

[tex](2x+20)=(3x+10)[/tex]

Solve for x. Subtract 2x from both sides:

[tex]20=x+10[/tex]

And subtract 10 from both sides:

[tex]x=10[/tex]

We know that:

[tex]m\angle 1 = 2x+20[/tex]

Substitute. Hence:

[tex]m\angle 1 =2(10)+20=40^\circ[/tex]

3rd one down is the answer

Answer:

Well let's count how many 65's there are, there are 3

So there needs to be 3 dots on the data plot on top of the section, 65.

Let's exclude some answers, D and B since they don't have 3 hovering over the 65(since there are three 65's).

Let's count how many 67's there are, there are 4.

We need to get rid of any answers that are more than 4 or less than 4 that are hovering over the section of 67. There are no answers to get rid of, let's move onto the next number, 68! There are four 68's. Let's also get rid of any answers that have more than 4 or less than 4 on the section above 68 since we're looking at that number. C is our answer!

Answer: 153.94

Step-by-step explanation: Formula for area of a circle: pi * r^2

First find the radius by dividing the diameter by 2: 14/2 = 7

Then plug the radius, 7, and pi, 3.14, into the formula:

(3.14) * (7^2) = 153.94 inches squared

Answer:

-9/16  is the answer

Answer:

T(c) = 100 + 3*c

Step-by-step explanation:

cost = fee + cost per chair * number of chairs

T(c) = 100 + 3*c

Answer:

T ( c)= $ 100 + $ 3 c

Step-by-step explanation:

Given that :-

To Find :-

Solution :-

Total Cost, T ( c) = Fee + cost per chair × no. of chairs.

T ( c) = $ 100 + $ 3 × c

T ( c) = $ 100 + $ 3 c

Answer:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

Step-by-step explanation:

If the terms on the left hand side of the equals are the same as the terms on the right hand side of the equals, there will be infinite solutions

12x+24x +18 = 36x +24 -6

Combining like terms

36x+18 = 36x +18

Subtracting 36x from each side

18 = 18

This is always true so  it does not matter what x is, the left had side will equal the right hand side

Answer:

✅On average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.

✅On average, it rains more in Zachary in a year.

Step-by-step explanation:

Mean annual rainfall on average = total amount of rainfall for the period of years ÷ 10

✔️Mean Annual rainfall for Albany (in.):

= (22.82 + 19.83 + 28.40 + 23.35 + 30.78 + 21.34 + 11.20 + 17.04 + 18.63 + 16.28) ÷ 10

= 20.967

✔️Mean Annual rainfall for Zachary (in.):

= (26.41 + 23.54 + 30.02 + 26.35 + 34.24 + 25.74 + 18.98 + 21.26 + 23.61 + 21.38) ÷ 10

= 25.153

✅Therefore, on average Albany gets 20.967 inches rain pee year and Zachary gets 25.153 inches rain per year.

✅On average, it rains more in Zachary in a year.

Answer:

You can do this through trial and error.

The answer is 260.

Step-by-step explanation:

Off the bat, we know all even numbers are multiples of 2 so 180 numbers to be precise. Now we find how many even Numbers are divisible by 18 so all factors of 18 should be satisfactory so 18, 36 etc. there are 20 of those so 180 - 20 = 160

now multiples of 3.  360 dived by 3 is 120 - 20 =100, 100+160 = 260

Answer:

1 and 2 are equivalent

For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.

Answer:

The quotient of n and 6 is n/6, as quotient means divide.

for example, if it was "the quotient of 24 and 6", it would be 24/6, which is 4.

Answer:

Step-by-step explanation:

radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit

Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2

                                   = (-15+7)^2 + (y+1)^2  = 17^2

                                  =14

(-15, 14) lies on this circle

Answer:

[tex]9600 \: {ft}^{2} \\ [/tex]

Step-by-step explanation:

Area of front rectangle -

= 2 ( length × breadth )

= 2 ( 40 × 30 )

= 2 ( 1200)

[tex] = {2400 \: ft}^{2} \\ [/tex]

Area of other rectangles -

= 4 ( length × breadth )

= 4 ( 60 × 30 )

= 4 ( 1800)

[tex] = 7200 \: {ft}^{2} \\ [/tex]

Surface area of the rectangular prism

[tex] = {2400 \: ft}^{2} + {7200 \: ft}^{2} \\ = {9600 \: ft}^{2} \\ [/tex]

Answer:

y = - 1/2x =0

Step-by-step explanation:

y = mx  + b

b = intercept

m = slope

The intercept is 0.

Slope: 0 - 1 / 0+2

Slope = -1/2
