Answer:

$70

Step-by-step explanation:

essentially, Judy paid 90% of the original price

therefore you can write this equation where 'x' equals the original price:

.9x = 63

x = 63/.9

x = 70

Answer:

b = 1/3

Step-by-step explanation:

6(b+1)=8

Solving for b

Distribute

6b +6 = 8

Subtract 6 from each side

6b+6-6 = 8-6

6b = 2

Divide by 6

6b/6 = 2/6

b = 1/3

Answer:

B = 61°

A = 29°

a = 10

Step-by-step explanation:

We are given;

c = 16, b = 14​

Since we are told that C is a right angle, it means that C = 90°

Thus using sine rule, we have;

c/sin C = b/sin B

16/sin 90 = 14/sin B

16/1 = 14/sin B

sin B = 14/16

sin B = 0.875

B = sin^(-1) 0.875

B ≈ 61°

Now, since C is a right angle, it means that c will be the hypotenuse of the triangle.

Thus, from pythagoras theorem, If the other side of the triangle is a, then;

a² + b² = c²

a² + 14² = 16²

a² = 16² - 14²

a² = 256 - 156

a² = 100

a = √100

a = 10

Since we know B and C, we can find A because sum of angles in a triangle is 180°.

Thus;

A = 180 - (B + C)

A = 180 - (61 + 90)

A = 29°

Answer:

[tex]y=-\frac{4}{5}x+\frac{74}{5}[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=\frac{5}{4} x-10[/tex]

From the given equation, we can identify clearly that the slope of this line is

[tex]\frac{5}{4}[/tex]. The negative reciprocal of [tex]\frac{5}{4}[/tex] is [tex]-\frac{4}{5}[/tex], so therefore, the slope of the line we're currently solving for is [tex]-\frac{4}{5}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{4}{5}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{4}{5}x+b[/tex]

Plug in the given point (11,6) and solve for b

[tex]6=-\frac{4}{5}(11)+b\\6=-\frac{44}{5}+b[/tex]

Add [tex]-\frac{44}{5}[/tex] to both sides to isolate b

[tex]6+\frac{44}{5}=-\frac{44}{5}+b+-\frac{44}{5}\\\frac{74}{5} =b[/tex]

Therefore, the y-intercept is [tex]\frac{74}{5}[/tex]. Plug this back into [tex]y=-\frac{4}{5}x+b[/tex]:

[tex]y=-\frac{4}{5}x+\frac{74}{5}[/tex]

I hope this helps!

Answer:

$36.97  

The cost of the meal was $32.57 and he used a 10% off coupon. You can make 10% equal to 0.1 because . Now do . This is the discount, so you want to subtract this from the original to get the actual price of the meal, .

The tax was 8% so this means he is adding

Answer:0 = 3x - 21

Step-by-step explanation:

From this given function we can take an  

x

common from its expression

i.e  

x

−

6

x

=

x

(

x

)

As we know that the product of two numbers is zero,when either one of them is zero

then in the above expression that we just factorised

the function can be zero when either  

x

=

0

or when  

x

=

6

i.e when  

x

=

Finally, our prize of all that math, the zeroes of the function are  

0

and

these numbers are called the zeroes of the function because when you put these values in

the function gives zero.

Answer:

D

Step-by-step explanation:

First find the slope of the line. The two points I will use are (0, 3) and (4, 2).

(2-3)/(4-0) = -(1/4). In all the equations below, the number/co-efficient before x is the slope of the line. D is the correct answer because you can rearrange the right side of it to get y = -(1/4)x+2. The co-efficient of x is -(1/4) so D is the right answer. Hope this helps! :)

Answer: D

Step-by-step explanation:

In order to have the same slope, in y=mx+b form, the two "m" must be equal.

Step 1 is to find the slope of the graph through two points. I choose the points (0,3) and (4,2)

slope is y2-y1/x2-x1 so 3-2/0-4 = -1/4

Now find which equation has the m of -1/4 and that's your answer

Hint its D.

Answer:

8m x 7m x 8m = 448m

Answer:

x =132

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

x = 46+86

x =132

Answer:

x=132 degree

Step-by-step explanation:

86 + 46 = x (sum of two interior opposite angle is equal to the exterior angle formed)

132 =x

therefore the value of x is 132 degree.

Answer:

8 units²

Step-by-step explanation:

The formula for the area of a triangle is a=[tex]\frac{bh}{2}[/tex], where a is area, b is base length, and h is height.

If we substitute b with 8 and 2 with h, we get a=[tex]\frac{2*8}{2}[/tex].

This can be immediately simplified to 8 by dividing both the numerator and denominator by 2.

Answer:

The correct value is t* = 2.797.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 25 - 1 = 24

99% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a  two-tailed confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 2.797.

Answer:

[tex]2.95\cdot 10^3\:\mathrm{km}[/tex]

Step-by-step explanation:

Distance is given by [tex]D=st[/tex], where [tex]s[/tex] represents speed or rate and [tex]t[/tex] represents time.

What we're given:

Thus, the distance covered by the airplane is:

[tex]d=885\cdot 3.\overline{3}=2,950\:\mathrm{km}[/tex]

In scientific notation:

[tex]2,950\:\mathrm{km}\implies\boxed{2.95\cdot 10^3\:\mathrm{km}}[/tex]

Answer:

Distance = speed * time

The distance is:

Answer:

The time it would take Kyle's mum is given as follows;

[tex]t = \dfrac{3 \cdot v^2+ 2\cdot v - 2}{v \cdot (v - 1) \cdot (v + 2)}[/tex]

Where v = Kyle's average rate

Step-by-step explanation:

The details of Kyle's mother's journey are;

The distance she drove = 12 miles

Her speed during the first third (12/3 = 4 miles), v₁ = 4 × Kyle's speed, v

Her speed in the second third(between 4 and 8 miles), v₂ = v₁ - 4

Her speed in the last third, v₃ = v₂ + 12

∴ v₁ = 4·v

v₂ = v₁ - 4 = 4·v - 4

v₃ = v₂ + 12 = 4·v - 4 + 12 = 4·v + 8

∴ t₁ = (t/3)/4 = t/12 = 4/(4·v) = 1/v

t₂ = 4/(4·v - 4) = 1/(v - 1)

t₃ = 4/(4·v + 8) = 1/(v + 2)

The total time, t = t₁ + t₂ + t₃

∴ t = 1/v + 1/(v - 1) + 1/(v + 2) = [tex]\dfrac{3 \cdot v^2+ 2\cdot v - 2}{v \cdot (v - 1) \cdot (v + 2)}[/tex]

The time it would take Kyle's mum to travel the same 12 miles by car that Kyle traveled on his bike, t = [tex]\dfrac{3 \cdot v^2+ 2\cdot v - 2}{v \cdot (v - 1) \cdot (v + 2)}[/tex]
