26: Solve For U
-4.2=u/5 + 8.3

Answer:

[(x + 6), (y + 1)]

Step-by-step explanation:

Vertices of the quadrilateral ABCD are,

A → (-5, 2)

B → (-3, 4)

C → (-2, 4)

D → (-1, 2)

By reflecting the given quadrilateral ABCD across x-axis to form the image quadrilateral A'B'C'D',

Rule for the reflection of a point across x-axis is,

(x, y) → (x , -y)

Coordinates of the image point A' will be,

A(-5, 2) → A'(-5, -2)

From the picture attached, point E is obtained by translation of point A'.

Rule for the translation of a point by h units right and k units up,

A'(x+h, y+k) → E(x', y')

By this rule,

A'(-5 + h, -2 + k) → E(1, -1)

By comparing coordinates of A' and E,

-5 + h = 1

h = 6

-2 + k = -1

k = 1

That means

Rule for the translation will be,

[(x + 6), (y + 1)]

Answer: k = -8.66

Step-by-step explanation:

We have the equation:

k*x + 5*y = 10

First, let's rewrite this as a line in the slope-intercept form:

5*y = 10 - k*x

y = 10/5 - (k/5)*x

y = -(k/5)*x + 2

Now, we want to make an angle of 30° with respect to the y-axis.

Then we can think on a triangle rectangle, where we know one angle of 30°, the adjacent cathetus will be equal to the difference between the y-component and the y-intercept, and the opposite cathetus will be equal to the x-component.

To get this, we first need to evaluate the function in one given point, let's use x = 5. (we could use any value of x here, i use 5 because it is easier)

y = -(k/5)*5 + 2

y = -k + 2

then the cathetus of our triangle will be:

adjacent cathetus: (y - 2) = (-k + 2 - 2) = -k

opposite cathetus: x = 5.

Now we know the relation:

Tan(a) = (opposite cathetus)/(adjacent cathetus)

where a = 30°

Then:

Tan(30°) = 5/(-k)

-k = 5/tan(0.577) = 8.66

k = -8.66

This is the value of k that we wanted to find.

Given:

At the store a cell phone cost 1.1 times as much as it sells online.

The cost of it is $888.98 online.

To find:

How much more does it cost from the store?

Solution:

It is given that,

Cost of a cell phone online = $888.98

At the store a cell phone cost 1.1 times as much as it sells online. So, cost of the cell phone at store is

[tex]1.1\times (888.98)=977.878 [/tex]

The cost of cell phone at store is $977.878 .

The difference between the cost of cell phone at store and online is

[tex]\$977.878 -\$888.98=\$88.898[/tex]

Therefore, the cell phone cost is $88.898 much more at the store.

Answer:

Option D

Step-by-step explanation:

From the spinner we see there are 5 colours in there.

These are;

Green, Yellow, Red, Purple, Blue.

This means that when it is spinned, there's possibility of getting only one colour per spin.

Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.

This means, all possible outcomes will be 5 × 2 = 10 outcomes.

With each colour possibly showing up with either tail or head.

Correct answer is Option D as it has 10 possible outcomes in the correct order.

Answer:

boys=30 girls=25

Step-by-step explanation:

if you add 6 and 5 and then you would get 11. 55 divided by 11 is 5. so then we would do 6*5 and 5*5 thats how i got my answer.

Answer:

The time the trip takes Kelly is approximately 34 minutes

Step-by-step explanation:

The topic examined by the question is the relationship between speed, distance traveled, and time which is presented here as follows;

[tex]Speed, \ S = \dfrac{Distance \ travelled \ 'd'}{Time \ taken \ 't'}[/tex]

The given parameters of the journey are;

The time it takes Mike to travel from point 'a' to point 'b' = 45 minutes

The speed with which Mike travels = 60 miles an hour

The speed with which Kelly travels the same trip = 80 miles an hour

Let 'd' represent the distance from point 'a' to point 'b', and let 't' represent the time the trip takes Kelly

For Mike, we have;

S = d/t

∴ d = S × t

Where;

S = 60 miles per hour

t = 45 minutes = 0.75 hour

d = 60 miles/hour × 0.75 hour = 45 miles

The distance from point 'a' to point 'b' = d = 45 miles

Similarly, from S = d/t, we have for Kelly the time 't' given as follows;

t = d/S

Where;

S = 80 miles/hour

d = 45 miles

∴ t = 45 miles/(80 miles/hour) = 9/16 hour = 9/16 hour × 60 min/hour = 33.75 minutes

The time the trip takes Kelly = 33.75 minutes ≈ 34 minutes.

Answer:

  E.  infinitely many

Step-by-step explanation:

The other pair of parallel sides (at right angles to the given sides) can be any length. Infinitely many rectangles can be formed.

Answer:

i think that the corect answer is A.0

Step-by-step explanation:

it is parallel and that means that it wont cross paths

Step-by-step explanation:

Since the sum of the angles in a straight line is 180, and we know that angle four is 120, to find angle 3, simply subtract 120 from 180.

Angle 3 is 180-120 = 60

Since we know 2 angles already, we have: 60 + 95 = 155. Now subtract that from 180.

Angle 1 is 180-155 = 25

Answer:

.75

Step-by-step explanation:

Answer:

20.8mm

Step-by-step explanation:

We know that an octagon has 8 sides, and since this is a regular octagon we can safely say that all sides are equal.

This means all sides are 2.6mm.

So if we run the calculation:

2.6mm × 8 = 20.8mm (Side Length × Number of Sides = Perimeter)

We have our final answer!

Step-by-step explanation:

Primero encontramos el valor de x,

5(x+9) = 2(x+30)

=> 5x + 45 = 2x + 60

=> 5x - 2x = 60 - 45

=> 3x = 15

[tex] = > x = \frac{15}{3} [/tex]

=> x = 5

Como tenemos el valor de x entonces,

LHS = 5(x+9) RHS = 2(x+30)

= 5(5+9) = 2(5+30)

= 5 × 14 = 70. = 2 × 35 = 70

Por tanto, el valor es,

5 (x + 9) = 2 (x + 30) = 70 (Ans)

Answer: $15.75

Step-by-step explanation:

From the question, we are informed that a storekeeper increased the price of hats by 5% and that the hat was originally priced at $15.00.

The new cost of the hat will be:

= $15.00 + (5% × $15.00)

= $15.00 + (5/100 × $15.00)

= $15.00 + (0.05 × $15.00)

= $15.00 + $0.75

= $15.75

The new cost of the hat is $15.75

Answer: Mr Smith bought 7 pepperoni pizza

Step-by-step explanation:

Step 1

cost of cheese pizza  =$11

pepperoni pizza cost =$12.50

let number cheese pizza be represented as c

and number of pepperoni pizza be represented as p

such that the total number of pizza  bought which equals 13 can be represented as

c+ p= 13

and total cost of both pizza  can be expressed as

11c+ 12.50p =153.50

Step 2 Solving

 c+ p= 13

11c+ 12.50p =153.50

By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2

11c+ 12.50p =153.50

11c+ 11p=143.

1.5p =10.5

p= 10.5/ 1.5 =7

c+ p= 13

c= 13-p =13-7=6

Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza

Answer:

4.85

Step-by-step explanation:

Given :

Negative 0.2 (x minus 4) = negative 1.7

-2(x - 4) = - 1.7

-2x + 8 = - 1.7

-2x = - 1.7 - 8

-2x = - 9.7

Divide both sides by - 2

-2x / 2 = - 9.7 / - 2

x = 4.85
