Find the value of a and b

Answer:

28 degrees

Step-by-step explanation:

152 is the exact same measure as angle 2.

To get to 180 you have to add 152 + angle 1

Angle one is the same as angle 3.

180 - 152 = 28

Step-by-step explanation:

8 pounds.... 4hours

x pounds.... 3 hours

x=3 ×8 :4

x=24 :4

x=6 pounds of trash

The number of pounds of trash should the volunteers pick up this month is 6.

Since  Last month, the volunteers picked up 8 pounds of trash in 4 hours. This month, the same group of volunteers will spend 3 hours picking up trash.

So here we can do

x=3 ×8 :4

x=24 :4

x=6

Hence, The number of pounds of trash should the volunteers pick up this month is 6.

Answer: x2 + 34x - 13

Step-by-step explanation:

STEP

1

Trying to factor by splitting the middle term

1.1     Factoring  x2+34x-13  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +34x  its coefficient is  34 .

The last term, "the constant", is  -13  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -13 = -13  

Step-2 : Find two factors of  -13  whose sum equals the coefficient of the middle term, which is   34 .

     -13    +    1    =    -12  

     -1    +    13    =    12  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

 x2 + 34x - 13

Answer:

Billy Bob Joe now has 18 jelly beans left

Step-by-step explanation:

Bob initially has 77 jelly beans, Sally initially has 12 jelly beans and Billy Bob Joe initially has 19 jelly beans.

If Bob gives 45 jelly beans to Sally, Bob now has 77 - 45 = 32 jelly beans and Sally now has 12 + 45 = 57 jelly beans.

Sally now gives 29 jelly beans to Billy Bob Joe. Sally now has 57 - 29 = 28 jelly beans and Billy Bob Joe now has 19 + 29 = 48 jelly beans.

If Billy Bob Joe now eats 30 jelly beans, he now has 48 - 30 = 18 jelly beans.

So, after eating 30 jelly beans, Billy Bob Joe now has 18 jelly beans left.

Answer:

O Dependent: miles; Independent: gallons

Step-by-step explanation:

An independent variable is one which can stand alone. Its values is not affected(gets changed) by change in other variable.

Example : your age

value of your age will not change in other factor like how much you run, sleep etc.

A dependent variable is one which cannot stand alone. Its values gets affected(gets changed) by change in other variable.

Example : weight: weight of human is dependent on food you eat and hence more you eat more is the chance of weight being increased.

hence, weight is dependent variable.

_______________________________________________________

Given

A car uses a gallon of gas for every 45 miles driven.

thus, there are two variable, which as identified is

miles and gallons

given that

in 1 gallon , car gets driven 45 miles

so if there are n gallons car will get driven 45*2 = 90 miles

in there are n gallons,  car will get driven 45*n= 45n miles

hence , miles is dependent on no of gallons hence

miles is dependent variable.

thus, we see there is relationship between miles and gallon as

miles = 45n,  where n is the no of gallons

here no of gallons is independent variable as its value can stand alone, its value does not change with miles.

hence

gallons is independent variable.

thus,

correct choice is

O Dependent: miles; Independent: gallons

Answer:

x = 12

Step-by-step explanation:

The attached figure shows the measures of the angles. Here, line a is parallel to line b.

Given that,

m∠3 = 128 and m∠6 = (10x + 8)

We need to find the value of x.

Here,

[tex]\angle 3 =\angle 6[/tex] (alternate interior angles)

So,

[tex]10x+8=128\\\\10x=128-8\\\\10x=120\\\\x=12[/tex]

So, the value of x is 12. Hence, the correct option is (D).

0.2×2+3.6-9 = -5

-5 = profit p

Answer:

Step-by-step explanation:

To get the zeros of the expression 2x(x - 5)(x+7), we are going to equate the expression to zero and find the corresponding value of x as shown;

2x(x - 5)(x+7) = 0

2x = 0

x-5 = 0

x+7 = 0

From 2x = 0

x = 0/2

x = 0

From x-5 = 0

x = 0+5

x = 5

From the equation x+7 = 0

x = 0-7

x = -7

Hence the values of the zeros are {-7, 0, 5}

Rough surfaces

Ex=carpet

The student unable to apply enough force to overcome the force of friction on rough surfaces.

A force is an influence that can change the motion of an object.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.

We need to find the type of  surface the student unable to apply enough force to overcome the force of friction.

A rough surface will have more friction because on the rough surface there will be more irregularities.

So rough surface is the student unable to apply enough force to overcome the force of friction.

Hence, the student unable to apply enough force to overcome the force of friction on rough surfaces.

Answer:

[tex]7ab^{2}[/tex]

Step-by-step explanation:

You take the cube root of each piece of the term separately:

7 x 7 x 7 = 343, so the cube root of 343 = 7

a^3 = a x a x a, so the cube root of a^3 = a

b^6 = b x b x b x b x b x b = b^2 x b^2 x b^2, so the cube root of b^6 = b^2

Answer:

90

Step-by-step explanation:

342-252=90

So, therefore, 252+90=342

Answer:

90

Step-by-step explanation:

Since the sum is 342 and we already know the first number is 252 we would take away 252 from 342 to get the amount of the second number.

(342-252=90)

We got 90 and to check we would add 252+90 which is =

(252+90=342)

The answer is 90
