Needed help for my math please

Mathematics
1 answer:
vesna_86 [32]3 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

(a)

\frac{a}{a} = 1 ( any value divided by itself = 1 )

(b)

\frac{a}{1} = a ( any value divide by 1 is the value itself )

(c)

\frac{a}{b} × \frac{c}{d} = \frac{ac}{bd}

The product of 2 fractions is the product of the numerators divided by the product of the denominators

(d)

\frac{a}{b} ÷ \frac{c}{d} = \frac{ad}{bc}

To divide 2 fractions, leave the first fraction, change division to multiplication and turn the second fraction upside down, that is

\frac{a}{b} ÷ \frac{c}{d} = \frac{a}{b} × \frac{d}{c} = \frac{ad}{bc}

(e)

\frac{a}{d} + \frac{b}{d} = \frac{a+b}{d}

Since the fractions have a like denominator, add the numerators leaving the denominator. This applies to subtraction also

(f)

\frac{a}{d} - \frac{b}{d} = \frac{a-b}{d}

See explanation for part (e)

Please help ? i have no clue what i’m doing
Anit [1.1K]

Step-by-step explanation:

2( l + w ) = perimeter of triangle

P = 2( 10+8 )

p= 2(18)

p= 36cm

Circle = pie (r) + d. recall d = 2r

P= 3.142 (4) + 8

P= 20.57~

so therefore= , 36 + 2(20.57)= 77.14cm ~ to the nearest tenths

Ebony but a four year treasury note that pay the equivalent of 3.8% simple interest. She invested $3000 more in a 9 year bond e
Anastasy [175]

Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",

Let,

  • The amount invested in treasury note will be = x
  • The amount invested in bond will be = (x + 3000)

then,

→ \frac{x\times 4\times 3.8}{100} +\frac{(3000+x)\times 9\times 4.6}{100}=5204

→       \frac{15.2x}{100}+\frac{(3000+x)\times 41.4}{100} =5204

→         \frac{15.2x}{100} +\frac{124200+41.4x}{100} =5204

→            \frac{15.2 x+124200+41.4x}{100} = 5204

→               56.6x+124200=520400

→                               56.6x=520400-124200

→                               56.6x=396200

→                                      x = \frac{396200}{56.6}

→                                         = 7000

Amount invested in bond will be:

= x+3000

= 7000+3000

= 10000    

Thus the above is the correct answer.
