jamal goes out for a coffee and a cake with his three friends. He has only £15.00 on him. He bought 4 coffees at £1.85 each and 4 identical cakes. The barista gave Jamal £2.20 change. Will Jamal’s change be enough to buy him 2 more cakes to take home to his mum and dad?

Answers

No he won’t . He starts with $15 .. you subtract $1.85 from 15 ( 4 times ) should get you to $7.6 thenn you subtract $2.20 from $7.6 ( 4 times ) which would get you to a negative so no he will not

A school conference room can seat a maximum of 83 people. The principal and two counselors need to meet with the school’s student athletes to discuss eligibility requirements. If each student must bring a parent with them, what is the maximum number of students that can attend each meeting?

Answers

Answer:

40 students

Step-by-step explanation:

We do not count the counselors or the principal because they are not students, so we do 83 - 3 = 80, now it is just simple division, for every student there is a parent, so we divide 80 in half, 80 / 2 = 40 students :D

Annabelle went to the grocery store and bought bottles of soda and bottles of juice.
Each bottle of soda has 30 grams of sugar and each bottle of juice has 1o grams of
sugar. Annabelle purchased 3 times as many bottles of juice as bottles of soda and
they all collectively contain 120 grams of sugar. Graphically solve a system of
equations in order to determine the number of bottles of soda purchased, T, and the
number of bottles of juice purchased, y.

Answers

Answer:

120 = 3y + t

Step-by-step explanation:

120 = 3y + t because you purchase 3 times as many y then t. Overall, your answer should end up as 120 by using an equation like this.

When James family went on the road to the carnival they were stuck in traffic. After a 20 minutes they are were 30 more miles left, after 35 minutes passed. How many more miles are left? If the fair is 58 miles away?

Answers

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Step-by-step explanation:

A circular mirror measures 24 cm in diameter.
The cake is cut in half. Work out the perimeter of half of the mirror.

Answers

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

The diameter of circular measure = 24 cm

We know that the perimeter of a circular shape is called the 'circumference', with the formula

Circumference of a circle = C = 2πr

When the mirror is cut into half, the diameter gets half as well.

Thus, the diameter of a half mirror = 24/2 = 12 cm

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror  = C = 2πr

                                                                           = 2(3.14)6

                                                                            = 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

2x − y = 11

x + 3y = −5

4

Answers

Answer:

(7, -3)

Step-by-step explanation:

Solve the system of linear equations

2x − y = 11

x + 3y = −5

by elimination by addition and subtraction.  Multiply the second equation by -2, obtaining

2x - y = 11

-2x - 6y = 10

------------------

     -7y = 21, which yields y = -3

Knowing that y = -3, we can now find the value of x.  Let's use the first equation for this purpose.  Substituting -3 for y, we get:

2x - (-3) = 11, or

2x = 11 + 3, or 2x = 14.  Thus, x = 7.

The solution is (7, -3).

-3

Answer:

Step-by-step explanation:

area of rectangle

l×w

(x+8)×x

x²+8x

The area of the rectangle is [tex]X^2 + 8X[/tex].

To find the area of a rectangle, we multiply its length by its width.

In this case, the length is (X + 8)

and the width is X.

so, we have,

Area = Length * Width

Area = (X + 8) * X

To simplify the expression, we need to distribute the X through the parentheses:

Area = X * X + 8 * X

Area = [tex]X^2 + 8X[/tex]

So, the area of the rectangle is [tex]X^2 + 8X[/tex].

A publisher makes books for a number of distributors. For one book, the charge to the distributor is represented by a fixed cost of $3000 plus $16 per book. a) How much would 600 books cost b) what is the cost per book if 600 are ordered c) what is the cost per book if 1000 are ordered

Answers

Answer:

a. $12,600

b. $21

c. $19

Step-by-step explanation:

a) The cost is $3000 plus $16 per book

For 600 books, we have

3000 + 16(600)

= 3000 + 9600 = $12,600

b) Cost per book will be;

12,690/600 = $21

c) for 1000

= 3000 + 16(1000)

= 3000 + 16,000 = 19,000

cost per book is 19,000/1000 = $19

First write the line equation.

y=mx+b is the format where m=slope, b= y intercept

y=-2x-3

plug each x in to see if they match the point

y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO

y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches

y= -2(-6) -3 = 12-3 = 0; point matches so YES

y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO

y = -2(3) -3 = -6-3= -9; point matches so YES

y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO

Step-by-step explanation:

Since, measure of all sides of the triangle has been given in the picture,

By applying cosine rule in the given triangle,

AC² = AB² + BC² - 2(AB)(BC)cos(B)

11² = 16² + 16² - 2(16)(16)cos(B)

121 = 256 + 256 - 512.cos(B)

121 - 512 = - 512.cos(B)

cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672

B = [tex]cos^{-1}(0.763672)[/tex]

B = 40.2°

write an equation in slope-intercepts form for the line that passes through (5, -4) and is perpendicular to the line described by 2x-10y=0

EXPLAIN what you did in each step to arrive at your answer plz

Answers

Answer: [tex]y=-5x+21[/tex]

Step-by-step explanation:

In slope intercept form : y=mx+c , m= slope , c= y-intercept.

Let [tex]L_1[/tex] be the line passing through (5, -4) and perpendicular to [tex]L_2: 2x-10y=0[/tex].

Rewrite [tex]L_2[/tex] in slope-intercept form

[tex]10y=2x\Rightarrow\ y=0.2x+0[/tex]

Here, Slope of [tex]L_2[/tex] = m = 0.2  

Let n be slope of [tex]L_1[/tex] .

Then  [tex]m\times n=-1[/tex]   [Product of slopes of perpendicular lines is -1.]

[tex]\Rightarrow\ n=\dfrac{-1}{m}=\dfrac{-1}{0.2}\\\\\Rightarrow\ n=-5[/tex]

Equation of a line that passes through (a,b) and have slope 'm' is given by :-

[tex](y-b)=m(x-a)[/tex]

So, Equation of [tex]L_1[/tex] :

[tex](y-(-4))=-5(x-5)\\\\\Rightarrow\ (y+4)=-5x+25\\\\\Rightarrow\ y=-5x+21[/tex]

The highest point in the mountains of Seattle is 5,833 meters above sea level. The lowest point in the valley is 57 meters below sea level. What is the difference between the highest and lowest point?

Answers

Answer: 5890 meters

Step-by-step explanation:

Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.

The lowest point in the valley is 57 meters below sea level.

in integers it is represented by -57 meters. [we use negative integer to represents "below"]

Difference between the highest and lowest point = Highest point - lowest point

=  5,833 meters -(-57) meters

= (5833 + 57) meters      [a-(-b)= a+b]

= 5890 meters

Hence, the required difference = 5890 meters
