A map has a scale of 1.5 in : 26 mi. If the distance between city A and City

alekssr [168]

Answer:

The real distance is 260 miles

Step-by-step explanation:

From the question;

1.5 inches in map is 26 miles

Thus;

15 inches will be x miles

To get the value of x, we do a cross-multiplication

we have this as:

15 * 26 = 1.5 * x

x = (15 * 26)/1.5

x = 10 * 26 = 260 miles

2 sin^2 (x) -5 sin (x) -3=0

andreyandreev [35.5K]

we have that

$2sin^{2} x-5sin x-3=0$

I. Rewrite the equation by substituting the expression u in for sin x.

$2u^{2} -5u-3=0$

II. Factor the quadratic expression. Rewrite the equation with factors instead of the original polynomial.

$2u^{2} -5u-3=0$ is equal to

using a graph calculator-----> see the attached figure

$(u-3)*(2u+1)=0$

III. Use the zero product property to solve the quadratic equation.

$(u-3)*(2u+1)=0$

(u-3)=0--------------> u=3

(2u+1)=0-------- 2u=-1------> u=-1/2-----> u=-0.5

IV. Rewrite your solutions to Part III by replacing u with sin x.

sin x=3--------> is not the solution (sin x can not be greater than 1)

sin x=-0.50------>is the solution

V. Solve the remaining equations for x, giving all solutions to the equation.

sin x=-0.50

if the sine is negative

then

x belong to the III or IV quadrant

we know that

sin 30°=0.50

the solution for the III quadrant is

x=180°+30°-------> x=210°

the solution for the IV quadrant is

x=360°-30°------> x=330°

In parallelogram EFGH, EJ = 6x + 3 and JG = 10x - 5 What is EG? A: 15 B: 12 C: 25 D: 30

Ne4ueva [31]

Answer:

D. 30

Step-by-step explanation:

It seems J is the intersection of diagonals.

We know diagonals of the parallelogram bisect each other.

It gives us:

EG = EJ + JG and
EJ = JG

Substitute and solve for x:

6x + 3 = 10x - 5
10x - 6x = 3 + 5
4x = 8
x = 2

Find the value of EJ:

EJ = 6*2 + 3 = 15

Find the value of EG:

EG = 2*EJ = 2*15 = 30

Correct choice is D

What are two ways to find the difference 13/50 - 4.93

PtichkaEL [24]

Answer:

Find the two ways to find the difference of : $\frac{13}{50} -4.93$

First way:

$\frac{13}{50}$

To convert this fraction into decimal.

We have to make the denominator 100.

i.,e

$\frac{13}{50} = \frac{13 \times 2}{50 \times 2}= \frac{26}{100} = 0.26$

now,

$0.26-4.93 = - 4.67$

Second way:

Convert $\frac{13}{50}$ to $\frac{26}{100}$ and 4.93 to $\frac{493}{100}$ ,

Now:

$\frac{26}{100}-\frac{493}{100} = \frac{26-493}{100} =-\frac{467}{100} = -4.67$
