Answer:

b=20

c=160

Step-by-step explanation:

b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.

Answer:

b = 20° ( vertically opposite angles are equal)

b + c = 180°

=> 20 + c = 180

=> c = 180 – 20

=> c = 160°

Answer:

- 10

Step-by-step explanation:

Step 1:

5 ( x - 4 ) = 7x       Equation

Step 2:

5x - 20 = 7x       Multiply

Step 3:

- 20 = 2x      Subtract

Step 4:

x = - 20 ÷ 2     Divide

Answer:

x = - 10

Answer:

3/13

Step-by-step explanation:

There are 28 students.  1 studies biology but not art.  1 studies neither subject.  Therefore, there are 26 students who study art.

Of the 26 students who study art, 6 also study biology.  So the probability is 6/26, which reduces to 3/13.

4. 1.24 x [tex]10^{7}[/tex]

5. 28,700

Answer:

19

Step-by-step explanation:

f(x) = 3x^2-3x + 1

Let x = -2

f(-2) = 3( -2)^2-3*-2 + 1

       = 3 * 4+6+1

       = 12 +6+1

       = 19

Answer:

The store will make 24 bags

total sales will be $55

Step-by-step explanation:

finding the number of bagsade by the store,

compare, 2 1/4 pounds= 1 bag

77 1/2 pounds= ? bags

cross multiplication

number of bags the store will make will be 24 4/9 bags.

considering the full bags only which are 24 then the number of full bags the store will make are 24 bags.

total sales will be 1 bag= $2.25

24bags= ?

croas multiplication

the store will make $55

Answer:

64 ounces

Step-by-step explanation:

Given.

Represent blue with b and yellow with y

b = 3

y = 8

Required

What's the value of y when b = 24

Represent the given and required parameters as ratio

3 : 8 and 24 : y

Turn the ratio to an equation

3 : 8 = 24 : y

Represent as fraction

⅜ = 24/y

Multiply both sides by y

⅜y = 24

Make y the subject

y = 24 * 8/3

y = 64

Hence:

64 ounces of yellow paints is required for 24 ounces of blue paints

Answer:

it is a rational

Step-by-step explanation:

The number is between integers, so it can't be an integer or a whole number. It's written as a ratio of two integers, so it's a rational number and not irrational.

Answer:

She made a profit of $6.85

Step-by-step explanation:

she started out with 25 mangos for $7.50

she then sold 12 mangos for $7.15 leaving her with 13 mangos

she then sold the remaning mangos for 7.20

add $7.15 to $7.20 and you get $14.35

thats the gross profit, and you subtract that by $7.50, how much she bought the mangos for, to get her total net profit.

which is $6.85

Step-by-step explanation:

Answer:

Leo started with $260

The balance of Vanessa and Leo after 7 weeks = $120

Step-by-step explanation:

Vanessa started $400

Vanesaa spending rate= $80/2weeks

In a week she would spend=$40/week

In 7 weeks should spend =40*7 = $280

Her balance after 7 weeks is =

$400 - $40 × x

$400 - $280

= $120

Leo spends at half of vanessa’s rate= $20/week

In 7 weeks leo will spend

$20 × x weeks

= 20 × 7 = $140

Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120

Hence, the amount Leo started with $120 + $140= $260

In order to confirm your above answer

The Equation can be given as

$400 - $40 ×x = $260 - $20 × x

Where x = 7 weeks

$400 -40x = 260 - 20x

$400 - 40× 7 = $260 - 20× 7

$400 - 280 = $260 - 140

$120 = $120

Answer:

The answer is no he is not correct, here's why.

C) No, he subtracted 1 and 9 instead of adding.

Step-by-step explanation:

Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:

[tex]c^{2}[/tex] = 32 + 12

[tex]c^{2}[/tex] = 9 + 1

[tex]c^{2}[/tex] = 8

c = 8

The legs Jerrod said are 3 ft and 1 ft

so A and B of the formula of pythagorean theorem could be:

[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]

[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]

This leads us to:

[tex]3^{2} + 1^{2} = c^{2}[/tex]

which is:

9 + 1 = [tex]c^{2}[/tex]

10 = [tex]c^{2}[/tex]

In this case, Jerrod had calculated wrong by instead of adding he had subtracted.

(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)

The correct statement for given situation is,

⇒ No, Jerrod made an error to finding the square root.

Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.

With steps are,

⇒ c² = 3² + 1²

⇒ c² = 9 + 1

⇒ c² = 8

⇒ c = 8

Now,

We have the steps are,

⇒ c² = 3² + 1²

⇒ c² = 9 + 1

⇒ c² = 8

⇒ c = 8

Clearly, In fourth step we get;

If c² = 8

Then, c = √ 8

But here we have;

⇒ c² = 8

⇒ c = 8

Hence, He made an error finding the square root.

Therefore, The correct statement for given situation is,

⇒ No, Jerrod made an error to finding the square root.

#SPJ6

Answer:

c

Step-by-step explanation:

a has a positive before negative, so its ruled out

1.3 is more than -0.45, so b is ruled out

everything in c is in the right order. -1/2 is -0.5 and -2/3 is -0.66, 7/12 is -.58

d is incorrect because -2/3 isnt more than 7/12

Step-by-step explanation:

Answer:

A. Rational number

Step-by-step explanation:

It is not a whole number or integer because it's a fraction. so it's the rational of a whole number.

Answer:

Real, Rational, Integer,

Step-by-step explanation:

Real: Most numbers are real so they just naturally fall into this category

Rational: -5 can be written as a fraction so it falls here

Integer: An integer is a number that can be positive, negative, or 0. as long as it doesnt have decmal points, it's an integer

Its not a whole number because whole numbers cannot contain a fraction, decimal, or negative value

Step-by-step explanation:

Answer:

George now has 20 paid vacation days

Step-by-step explanation:

The given parameters are;

The number of years George has worked for the tech company = 5 years

The amount George makes annually while working for the company = $81,536

The starting amount of paid vacation time George has each year = 8 days

The annual increase in the amount of paid vacation time George has each year = 3 days

The maximum number of days of paid vacation allowable = 30 days

a. The number of paid vacation days George now has is given as follows;

The first year George had 8 days paid vacation

The next year George had 8 + 3 = 11 days paid vacation

The third year George had 11 + 3 = 14 days paid vacation

The fourth year George had 14 + 3 = 17 days paid vacation

The fifth year George had 17 + 3 = 20 days paid vacation

Therefore, George now has 20 paid vacation days.
