Answer:

$25,226

Step-by-step explanation:

We know that one billion is equal to 1,000 millions

So, we first multiply 80.8 by 1,000 so we can use millions as our unit.

Which gives you $80,800

So, East Dakota spent $80,800 million in 2016 for the 3.203 million people. Right now, we just ignore the "million" part and divide 80,800 by 3.203 which is around 25,226.35029659694

Now we just round it to the nearest dollar and since the tens place is only at 3, we round down.

Hence, our answer is $25,226

Let the normal speed = x mph

The way to his grandmothers they drove 2x miles

Return trip was 2.25(x-5)

Set those equal and solve for x:

2x = 2.25(x-5)

Simplify:

2x = 2.25x -11.25

Subtract 2.25x from both sides:

-0.25x = -11.25

Divide both sides by-0.25:

X = 45

The usual speed is 45 mph.

So now 2 hours at 45 mph = 90 miles to his grandmothers house

Answer:

90 miles

Answer:

a) 12 ft for the length and the width

b) 7 ft as the length for each side

Step-by-step explanation:

a) Area = length x width

Since the shape is a square, that means that the length and the width have to be the same.

Because of this you have to square root 144 and you get 12 since 12x12 = 144.

b) For perimeter, this is the sum of all sides. Since a square has 4 sides and all these sides must be the same length since the shape is a square, then you have to do 28 ÷ 4 and you get 7 as your answer

Step-by-step explanation:

Total amount to generate at fundraiser = $8000

Amount donated by Bethany family = $60

The percentage of Bethany's donation towards the fundraiser is :

Let percentage = x

x% of 8000 = 60

x/100 * 8000 = 60

0.01x * 8000 = 60

80x = 60

Divide both sides by des by 80

80x / 80 = 60 / 80

x = 0.75

Answer:

16

Step-by-step explanation:

The distance is given by

d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)

Since the x values are the same

d = sqrt(  ( y2-y1) ^2)

d = sqrt(  (( -6 - 10)^2))

d =  sqrt((-16) ^2)

d = 16

We can also just find the number of squares between the points since the x value is the same.

Step by step explanation:

Circle numbers - 545 and 110 , 53

Underline - question - How much did they make on Tuesday?

Box - key words How Much

Evaluate and draw 545/110 = 5.95 per burger, so then you would multiply 53 x 5.95

Solve and check 53 x 5.95 = _______ your answer

The answer is below

Step-by-step explanation:

1) A triangle is a polygon with three sides and three angles. There are different types of triangles such as obtuse, scalene, right angle, equilateral and isosceles triangle.

Given that triangle ABC is right angled and AC = 25 cm = hypotenuse and BC = 15 cm. Using Pythagoras:

AC² = BC² + AB²

25² = AB² + 15²

AB² = 25² - 15²

AB² = 400

AB = √400

AB = 20 cm

Using sine rule:

[tex]\frac{sin(B)}{AC}=\frac{sin(A)}{BC}=\frac{sin(C)}{AB}\\\\But\ \angle B= 90^o(right\ angle)\ hence:\\\\ \frac{sin(B)}{AC}=\frac{sin(A)}{BC}\\\\\frac{sin(90)}{25}=\frac{sin(A)}{15}\\\\sin(A)=\frac{sin(90)}{25}*15\\\\sin(A)=0.6\\\\A=sin^{-1}(0.6)\\\\A=36.87^o[/tex]

2)

Using Pythagoras:

hypotenuse² = 8² + 6²

hypotenuse² = 100

hypotenuse = √100

hypotenuse = 10

Using sine rule:

[tex]\frac{sin(x)}{8}=\frac{sin(90)}{10}\\\\sin(x)=\frac{sin(90)}{10}*8\\\\sin(x)=0.8\\\\x=sin^{-1}(0.8)\\\\x=53.13 ^o[/tex]

Answer:

-16t²+17t+7=11

==>16t²-17t+4=0

Δ=17²-4*4*16=33

==>t= (17-√33)/32=0.351732... (s)≈0.35 (s)

or t=(17+√33)/32=0.710767 (s)≈0.71 (s)

Answer:

X = 38.7°

Step-by-step explanation:

Reference angle = x

Opposite side length = 8 cm

Adjacent side length = 10 cm

Applying trigonometric ratio formula, we have:

[tex] tan(x) = \frac{8}{10} [/tex]

[tex] x = tan^{-1}(\frac{8}{10}) [/tex]

[tex] x = 38.7 [/tex]

x = 38.7° (to the nearest tenth)

Answer: 3 mph.

Because....

3/4 of a mile is 0.75 miles.

0.75 miles = 15 minutes

X = 15 * 1 / 0.75

X = 20 minutes takes a mile to travel

20 minutes = 1 mile

60 minutes = X

Clearing X would give:

X = 60/20

X = 3 miles per hour.

Luis rides 3 miles per hour.
