Mathematics
1 answer:
mart [117]3 years ago
5 0

Answer:

shape AREA= 35cm^2

Step-by-step explanation:

you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.

A=h/2(b1 + b2) for trapezoid

A=2/2((4+4)+4)

A=1*12

A=12cm^2

A=bh/2. for TRIANGLE

A=1/2((4+4)*5.75)

A=1/2(46)

A=23cm^2

shape AREA= triangle AREA + trapezoid AREA

shape AREA=12cm^2 + 23cm^2

shape AREA= 35cm^2

Convert the percent to a decimal
Zanzabum

Answer:

40.0

18%

14.375%

1/250

38

6325

Step-by-step explanation:

Convert the percent to a decimal  4,000%

4000% = 4000/100 = 40.0

Convert the decimal or whole number to a percent.

0.36 * 1/2

= 0.36/2 * 100

= 0.18 * 100

= 18%

Convert the decimal or whole number to a percent.

1.15 * 1/8

= 1.15/8 * 100

= 14.375%

Convert the percent to a reduced fraction, mixed number, or whole number.

0.4%

= 0.4/100

= 1/250

Solve for the portion (in $). Round to hundredths when necessary.

9  1/2% of $400 = 19/2% x 400

= 0.095 x 400

= 38

Solve for the portion. Round to hundredths when necessary.

What number is 253% of 2,500?

253/100 x 2500

= 2.53 x 2500

= 6325

(Multiple choice) One factor of 9x^4 - 6x^3 + 3x^2 is:
DIA [1.3K]
So it's like 'which one of the number given is a factor of, say, 10' and the choices are 4,5,7,9. the answer is 5 so just factor out the equation

the factored out form is
factor out the 3x^2 and get
(3x^2)(3x^2-2x+1)
and 3x^2-2x+1 is the fourth choice

Enter the value of y that makes the given equatlon true.<br> 15y +3= 6
Lunna [17]

Answer:

y = 1/5 or y = 0.2

Step-by-step explanation:

15y +3= 6\\15y+3-3=6-3\leftarrow \text {Subtraction Property of Equality} \\15y=3\\\\\frac{15y}{15} =\frac{3}{15} \leftarrow \text {Divsion Property of Equality}\\

y=\frac{3}{15}\\\frac{3/3}{15/3} = \frac{1}{5} \leftarrow \text {Simplifying the Answer}\\\boxed{y=\frac{1}{5}}
