Can a remainder in a division problem equal the divisor
Rufina [12.5K]
Well the answer is No.A remainder will always be smaller than the divisor ,because the divisor is the one that used to divide the dividend and the remaining number that cannot be divided by the divisor is called the remainder.

Area of triangle=1/2(base×height)
360=1/2((4x-2)(7x+5))
720=(4x-2)(7x+5)
FOIL the binomial
720=28x^2+6x-10
Bring 720 to the other side
28x^2+6x-10-720=0
28x^2+6x-730=0
Factor 2 out
2(14x^2+3x-365)=0
Factor 2(14x+73)(x-5)=0
x-5=0
x=5
It can't be 14x-73=0 because the length can't be negative.
You're welcome.

Write the equation of a line that is
zvonat [6]

Answer:

y=0.5x-5

Step-by-step explanation:

Since the equation is parallel, this means that the slope remains the same which is 0.5.

The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.

-2=0.5(6)+b

When solving for b, it will equal to -5.

Therefore the new equation that is parallel is y=0.5x-5

A tourist looks out from the observation deck of the Space Needle in Seattle. The deck is at a height of 520 ft. She sees her fr
evablogger [386]

Answer:

40 feet

Step-by-step explanation:

Given : The deck is at a height of 520 ft. She sees her friend on the ground below at an angle of depression of 85.6 degrees.

To Find : What is the distance between the two? Round your answer to the nearest tenth of a foot.

Solution :

Refer the attached figure

Height of deck =AB =520 ft.

Angle of depression ∠C = 85.6°

We are supposed to find length of BC i.e. distance between two.

We will use trigonometric ratios :

tan \theta = \frac{perpendicular}{base}

tan 85.6^{\circ} = \frac{AB}{BC}

12.99615= \frac{520}{BC}

BC= \frac{520}{12.99615}

BC= 40

Thus the distance between two is 40 feet
