What is the area of the figure below? (A= 1/2.(b1+b2)) explain how u find the asnwer please ❤️

Answer:

Santosh purchased 4 new and 4 used DVDs.

Step-by-step explanation:

From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:

15x+5y=80, where:

x refers to the number of new DVDs

y refers to the number of used DVDs

Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:

15x+5x=80

20x=80

x=80/20

x=4

According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Answer:

Step-by-step explanation:

if 45+47=t and t=45+47    t would equal 92 in both

45+47<t than t<45+47

so basically its saying 92<t (92is less than t)  and t<92 (t is greater than 92)

he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92

hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...

Answer:

45

Step-by-step explanation:

First we convert 1/5 into a decimal, .2, then we divide 9 by .2 giving you 45.

To check this multiply 45 by .2 giving you 9.

Answer:

Mmm either B or D one of those two

Answer: -13

Step-by-step explanation:

1. Isolate x: move 5 to the otherside

=> -2x-6=4*5 => -2x-6=20

2. Move 6 to the otherside: -2x=20+6 => -2x=26

3. Divide both sides by -2

=> x=26/-2 => x=-13

Have a nice day! :D

Answer:

x = 2.57

Step-by-step explanation:

6/x = 7/3

7x = 18

x = 2.57

check:

if x = 2.57

then:

2.57/6 = 3/7

0.4283 = 0.4283

that checks as correct

The LCM, or least common multiple, of 6 and 8 is 24.

Answer: 2

Step-by-step explanation:

First you find the multiples of 6 and 8 then you do this.

2x3

2x2x2x2x2x4

Then you circle the 2’s and so the lcm on 6 of six and 8 is 2.

Answer:

3.9375 hours

Step-by-step explanation:

Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together

This is calculated as

1/Time it would take them to work together = 1/ Number of hours Mark mopped + 1/ Number of hours Sue mopped

= 1/T = 1/7 + 1/9

Lowest common denominator = 63

1/T = 9 + 7/63

1/T = 16/63

T = 63/16

T = 3.9375 hours

Answer:

x = 4

Step-by-step explanation:

DE / XY = EF / YZ

5 / 10 = 2x-1 / 14

cross-multiply:

10(2x-1) = 14(5)

20x - 10 = 70

20x = 80

x = 4

The ratio of their corresponding side will remain constant. Then the value of x is 4.

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two triangles are ΔDEF and ΔXYZ.

It is given that the ΔDEF and ΔXYZ are similar.

Then the ratio of their corresponding side will remain constant. That is

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]

From the first two, we have

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]

On simplifying, we have the value of x

x = 4

Step-by-step explanation:

step 1. wow! 670° I think you mean 67°

step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle

step 3. x + 102 + 67 = 180

step 4. x + 169 = 180

step 5. x = 11°.

Answer:

76-25= 51

Step-by-step explanation:

Answer:

A. 51

Given:

Total number of students: T = 147

Number of students taking math : M = 95

Number of students taking science : S = 73

Number of students taking both math and science = 52

To find:

The theoretical probability of randomly choosing a student who is taking math.

Solution:

It is given that,

Total number of students (T) = 147

Number of students taking math (M) = 95

So, he theoretical probability of randomly choosing a student who is taking math is:

[tex]P(M)=\dfrac{\text{Number of students taking math}}{\text{Total number of students}}\times 100\%[/tex]

[tex]P(M)=\dfrac{95}{147}\times 100\%[/tex]

[tex]P(M)=64.62585\%[/tex]

[tex]P(M)\approx 64.6\%[/tex]

64.6% is the theoretical probability of randomly choosing a student who is taking math.

Hence, option C is correct.
