Answer:

- 38

Step-by-step explanation:

Here in this question, we have to simplify a certain numeric term to get a simple answer.

The expression is ( - 6 times + 3 ) + ( 5 times - 4 )

= - ( 6 times 3 ) + (5 times - 4)

= - ( 6 × 3 ) - ( 5 × 4 )

= - 18 - 20

= - 38 (Answer)

If the polar coordinates of a point are given by (9.77 m, θ) and the rectangular coordinates are given by (x, 3.50 m), determine

Artyom0805 [142]

Answer:

the solutions are (9,12 m , 0.366 rad) and (-9,12 m , 1.936 rad)

Step-by-step explanation:

given the polar coordinates (r=9.77 m , θ) and (x, y=3.50 m) , since we know that

x²+y²=r² → x = ±√(r²-y²) = ±√(9.77 ²-3.50 ²)= ± 9,12 m

then

x = r* cos θ → for θ = cos ⁻¹ (x/r)

thus

for x= 9,12 m → θ = cos ⁻¹ (9,12 m/9.77 m) = 0.366 rad

for x= -9,12 m → θ = 0.366 rad + π/2 rad = 1.936 rad

therefore the solutions are (9,12 m , 0.366 rad) and (-9,12 m , 1.936 rad)

1. Andy has 5 pots, and each pot can hold 3/8 pound of soil. how much soil does he need to fill all of the pots?

elena-s [515]

(1) $1\frac{7}{8}$ pounds of soil (2) $\frac{35}{2}$ (3) 33

Solution:

(1) Number of pots = 5

Quantity of soil each pot can hold = $\frac{3}{8}$ pounds

Quantity of soil need to fill all the pots = $5\times \frac{3}{8}$

= $\frac{15}{8}$ pounds

= $1\frac{7}{8}$ pounds

Therefore, $1\frac{7}{8}$ pounds of soil need to fill all of the pots.

(2) To find the product of $4\frac{2}{3}$ and $3\frac{3}{4}$ .

Let us first convert the mixed fraction into improper fraction.

$4\frac{2}{3}\times3\frac{3}{4}=\frac{(4\times3)+2}{3}\times\frac{(3\times4)+3}{4}$

$=\frac{14}{3}\times\frac{15}{4}$

$=\frac{210}{12}$

This can be simplified. Divide both numerator and denominator by 6.

$=\frac{35}{2}$

$4\frac{2}{3}\times3\frac{3}{4}=\frac{35}{2}$

(3) To evaluate the expression 12x + 6 for $x=2\frac{1}{4}$ .

Let us first convert the mixed fraction into improper fraction.

$x=\frac{(2\times4)+1}{4}=\frac{9}{4}$

$12x+6=12(\frac{9}{4})+6$

$=(\frac{108}{4})+6$

$=27+6$

12x + 6 = 33
