Mathematics
1 answer:
Alina [70]4 years ago
7 0

Step-by-step explanation:

Haley: 10x + 155

brother: 230-15x

10x+155=230-15x

25x + 155 = 230

25x = 75

x = 3 weeks

10(3)+155= 30+155= $185 for Haley

230-15(3)= 230-45= $185 for brother

Given a triangle ABC at A = ( - 1, 3 ) B = ( 1, - 1 ) C = ( 2, 2 ) and if the triangle is rotated 90 ° clockwise about the point
lidiya [134]

Answer:

The coordinates of A' are (6,6).

Step-by-step explanation:

It is given that in triangle ABC, A = (-1, 3), B = (1, - 1) and C = (2, 2).

If a point is rotated 90 ° clockwise about the point ( a,b ), then

(x,y)\rightarrow ((y-b)+a,-(x-a)+b)

It is given that the triangle is rotated 90 ° clockwise about the point ( 4, 1 ). So, a=4 and b=1.

(x,y)\rightarrow ((y-1)+4,-(x-4)+1)

(x,y)\rightarrow (y+3,-x+5)

The coordinates of A are (-1,3), So, the coordinates of A' are

A(-1,3)\rightarrow A'(3+3,-(-1)+5)

A(-1,3)\rightarrow A'(6,6)

Therefore the coordinates of A' are (6,6).

seven out of every 8 students surveyed owns a bike. The difference between the number of students who own a bike and those who d
guajiro [1.7K]
So if x people were surveyed, \frac{7}{8} people owned a bike and \frac{1}{8}  did not.

The difference between them is 72:
\frac{7}{8} x-\frac{1}{8} [/tex] =72
so this means that
\frac{6}{8} x=72

let's simplify:

\frac{3}{4} x=72

and divide by 3:

\frac{1}{4} x=24

and mupliply by 4:

x=96

so 96 people were surveyed

Write an equation to represent the following: Three consecutive integers add up to 11 more than the smallest.
mr Goodwill [35]

Answer:


Step-by-step explanation:

First we have to assume the smallest integer.

Let,

the smallest integer is  x

So, the other two integers are-

x+1  and   x+2

Now,  

the sum of these 3 integers is greater than smallest integer by  11

So, we get

x+(x+1)+(x+2) =x+11

This is the required equation.

Which is true about x, the quotient of the division problem shown below? х 81 918 O The quotient contains a repeating decimal. O
Sergio [31]

Answer:

The answer is choice 2 and 3, that is "The quotient has a final decimal and the whole number is less than 11".

Step-by-step explanation:

The product of a ratio: amount (r) over other(s) (variance from 0) becomes mandatory to note this quotient and in the following case Thus q is = 0.0882352941.

\to \frac{81}{918}= 0.0882352941

It wasn't a repeating decimal, however a final decimal, so it's got an end.

Its quotient may be less than 11 in total.

Numbers of W = {0,1,2, ...} and 0 < 11 are provided for this entire series of data therefore It's real .
