Mathematics
1 answer:
Katyanochek1 [597]3 years ago
6 0

Answer:

the answer is 2.87

Step-by-step explanation:

use the pythagorean theorem

2^2+b^2=4^2

that goes to b= 3.5

for the triangle with x you also need to use the pythagorean theorem

2^{2}+x^{2}=3.5^{2}

4+x^{2}=12.25

subtract 4 on both sides

x^{2}=8.25

\sqrt{x}=\sqrt{8.25}

x=2.87

A trapezoid is 64cm^2. The height is 12 cm and one base is 4cm. What is the length of the missing base?
Debora [2.8K]

Answer:

20/3

Step-by-step

(base1+base2)/2 * height = area of a trapezoid

64/12=16/3

16/3*2 = 32/3

32/3-4 = 20/3

Ten times an integer is added to seven times it’s square. If the result is 152, what was the original number?
Bess [88]

Answer:

Required number is 4.

Step-by-step explanation:

Let the required number be a.

Given,

Sum of ten times the integer and seven times it’s square is 152.

= > Ten times of a + seven times of it's square = 152

= > 10( a ) + 7( a )^2 = 152

= > 10a + 7a^2 - 152 = 0

= > 7a^2 + 10a - 152 = 0

= > 7a^2 + ( 38 - 28 )a - 152 = 0

= > 7a^2 + 38a - 28a - 152 = 0

= > a( 7a + 38 ) - 4( 7a + 38 ) = 0

= > ( a - 4 )( 7a + 38 ) = 0

= > a = 4 or - 38 / 7

Hence the required number is 4.
