Solution

              To   write   0.37   in  expanded  form   using  powers  of  ten

              0.37   can  be   written   as

              0.37  =  0.30  +  0.07

              Since ,

                              0.30    =   3/10

                              0.07    =   7/ 100

              Therefore  ,

                          0.37  =    3/10  +  7/ 100

                                   =    3 x (1 / 10)  +  7 x (1 / 100)

                        Hence , option   C

Triangle DEF has an angle D measuring 25 degrees and an angle E
andrew-mc [135]

Answer:

The angle F of the triangle DEF measures 105 degrees.

Step-by-step explanation:

Given that triangle DEF has an angle D measuring 25 degrees and an angle E measuring 50 degrees, to determine what is the measure of angle F in degrees, knowing that the sum of the internal angles of every triangle gives a total of 180 degrees, we must perform the following calculation:

180 - 50 - 25 = F

130 - 25 = F

105 = F

Therefore, the angle F of the triangle DEF measures 105 degrees.

Refer to the following distribution:Cost of Textbooks Frequency $25 up to $35 2 S35 up to $45 5$45 up to $55 7$55 up to $65 20 S
soldi70 [24.7K]

Answer:

Relative\ Frequency = 0.04

Step-by-step explanation:

Given

Cost of Textbooks ---- Frequency

$25 up to $35  -----      2

$35 up to $45 -------     5

$45 up to $55  -------    7

$55 up to $65   ------    20

$65 up to $75   ----   -- 16

Required

Determine the relative class frequency for the $25 up to $35 class

First, we need to get the total frequency

Total = 2 + 5 + 7 + 20 + 16

Total = 50

Next, is to write out the frequency of $25 up to $35 class

Frequency = 2

Divide this frequency by the total frequency; This gives the relative frequency

Relative\ Frequency = \frac{Frequency}{Total}

Relative\ Frequency = \frac{2}{50}

Relative\ Frequency = 0.04

Hence;

sveta [45]

Answer:

x = 1

Step-by-step explanation:

  • 2x^2 + 3 = 5
  • 2x^2 = 5 - 3
  • 2x^2 = 2
  • x^2 = 2/2
  • x = \| 1
  • x = 1

What mistake did this student make?
Novay_Z [31]
X=-2 not 2.


EXPLANATION:

x-2y=12
-3x+y=-1
x-2y=12
2(-3x+y)=-1
x-2y=12
-6x+2y=-2
-5x=10
5x/-5=10/-5
x=-2
