Answers

Answer 1

Answer:

The answer would be A.

Hopes this you. Have a good day!!

Answer 2

Answer:

Prime numbers are those that cannot be divided by another number (other than themselves and 1). In other words, prime numbers have factors of themselves and 1.

For example, 3 is a prime number because its only factors are 3 and 1.

6 is not a prime number because it can be factored to 3*2.

Therefore, the correct answer is a. 3,11,23,31

What is the slope y+2=1/4(x-3)

Answers

Answer:

[tex]m=\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]y+2=\frac{1}{4}(x-3)[/tex]

Required

Find the slope

[tex]y+2=\frac{1}{4}(x-3)[/tex]

Subtract 2 from both sides

[tex]y+2-2=\frac{1}{4}(x-3) - 2[/tex]

[tex]y=\frac{1}{4}(x-3) - 2[/tex]

Open bracket

[tex]y=\frac{1}{4}x-\frac{1}{4}*3 - 2[/tex]

[tex]y=\frac{1}{4}x-\frac{3}{4} - 2[/tex]

Take LCM

[tex]y=\frac{1}{4}x+\frac{-3 - 8}{4}[/tex]

[tex]y=\frac{1}{4}x+\frac{-11}{4}[/tex]

[tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]

An equation has the form:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparing: [tex]y = mx + b[/tex] and [tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]

[tex]m=\frac{1}{4}[/tex]

So, the slope is 1/4

Answer:

The answer should be 3cm

Step-by-step explanation:

The way you worded it was kind of confusing so pardon me if the answer isnt the correct answer you were looking for. But I suppose that if 1 cm is 50 in. than 150 in. would be 3 cm. Because 50 + 50 + 50 = 150. And if it is 1 cm. per 50 in. than that would be 3 cm. I hope this answered your question! And if not.. again, im sorry.

Andy's little brother has a toy box that
contains 2 blue race cars, 1 green race car,
and 1 red race car. Andy removes 2 race cars
from the toy box without looking. If Andy
removes a blue car first and does not replace
it, which best represents the sample space
for the cars Andy removes?

Answers

Answer:

c.

Step-by-step explanation:

The solution is Option C.

Sample space is  set A = { blue , blue } , { blue , green } , { blue , red }

What is union and intersection of sets?

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the sample space be represented as set A

Now , the equation will be

The number of blue cars = 2 blue cars

The number of green cars = 1 green car

The number of red cars = 1 red car

So , the total number of cars = 2 + 1 + 1 = 4 cars

Now , Andy removes 2 race cars from the toy box without looking

Let the first removed car be a blue car

So , the second car can have any value including a blue , green or white

And , the sample space is given by set A

Set A = { blue , blue } , { blue , green } , { blue , red }

Hence , the set is { blue , blue } , { blue , green } , { blue , red }

Q
Timo concluded:
"It's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations,
so the quadrilaterals are not similar."

Answers

Answer:

c

Step-by-step explanation:

The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.

What is rigid transformation?Rotations, reflections, and translations are known as rigid transformations. They do not change the size or shape of a figure, they simply move it. These rigid transformations preserve congruence.

What is dilation?Dilation is not a rigid transformation, since they change the size of a figure. Dilation would not change the shape but changes the sizeThis would give us a similar, but not congruent figure.

Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".

A clothing outlet had a sale on jackets. A jacket priced at $233 was on sale, selling for 70% (use 0.7) of its price. How much did customers have to pay for the jacket (ignore taxes)?

Answers

Answer:
$163.10
Explanation:
70% = 7/10 = 0.7
$233 x 0.7 = $163.10

Answer:

Jackets cost $69.90.

Step-by-step explanation:

1. Multiply $233 by 70% (.70 as a decimal) to find how much less the jacket is.

2. Subtract that answer from the cost of the jacket.

233 * .70 = 163.1

233.00

163.10

$69.90

You can also multiply $233 by 30% and not have to subtract because your answer would BE the cost (70% + 30% = 100%).

233 * .30 = 69.90                 $69.90

[3x-2]÷4=2x-8

Can someone help

Answers

Answer:

Step-by-step explanation:

[3x-2]÷4=2x-8

3x-2 = 4·(2x-8)

3x-2 = 8x-32

-2 = 5x-32

30 = 5x

x = 6

Answer:

(3x-2)/4= 2x-8  x=6

Step-by-step explanation:

(3x-2)/4 times 4= 2x-8

Multiply both sides by 4

3x-2/4 times 4= 2x  times 4-8 time 4

Simplify

3x= 8x = 8x-30-8x

Subtract 8x from both sides

3x-8x=8x-30-8x

Simplify

-5x=-30

Divide both sides by -5

-5x/-5 = -30/-5

Simplify so you get x=6

4. The price of a sweater is $5 less than the price of the shirt. If four sweaters and
three shirts cost $200, find the cost of each shirt and sweater.

Answers

Answer:

Form an equation:

let x be the price of a shirt

Then, the price of a sweater would be x - 5

So you would have:

4(x - 5) + 3x = 200

simplify

4x - 20 + 3x = 200

7x - 20 = 200

add 20 to both sides

7x = 220

divide both sides by 7

x = about 31.43

That means the cost of the sweater would be 31.43 - 5 = 26.43

Answers

Answer:

See below.

Step-by-step explanation:

STEP 1:  If you write the given terms all with denominators of 16, they are 28/16, 25/16, 22/16, 19/16, __, ____, ____, 7/16, 4/16.

STEP 2: The terms decrease by 3/16 for each step.

RULE: Term 1 = 7/4 and term (n + 1) = term 'n' - 3/16

The operation for increasing by the same amount every step is addition.

The operation for decreasing by the same amount every step is subtraction.

STEP 3: The rule is that the terms decrease by 3/16 at each step.

So the next 3 terms after 19/16 will be 16/16, 13/16, and 10/16.

Reformat them and you have 1, 13/16, 5/8.

So now the completed sequence is 1&3/4, 1&9/16, 1&3/8, 1&3/16, 1, 13/16, 5/8, 7/16, 1/4.
