QUICK ANSWER PLEASE The left and right page numbers of an open book are two consecutive integers whose sum is 269. Find these page numbers.
Answer:
134 and 135
Because 269/2 is 134.5, so you know that one is 134 and the other is 135.
The page numbers are 134 and 135
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Given:
The left and right page numbers of an open book are two consecutive integers whose sum is 269.
Let two consecutive integers are n, n+1.
Then,
the sum of two consecutive integers is 269.
According to the question,
n + n + 1 = 269
2n + 1 = 269
2n = 268
n = 134
The integers are 134 and 135.
Therefore, integers are 134 and 135.

You and some friends have $30. You want to order large
pizzas (p) that are $9 eachand drinks (d) that cost $1 each.
Write and graph an inequality that shows how many pizzas
and drinks can you order.?
1.
Look at the number line shown below.
32
Which word problems or inequalities could have a solution represented by the
number line?
Select all that apply.
A. Christopher has read for more than 32 minutes.
B. Christopher has read for less than 32 minutes.
C. Christopher has read for 32 minutes.
D. x < 32
E. x > 32
F. X = 32
Answer:
A -> E
B -> D
C -> F
Step-by-step explanation:
In all cases, we represent minutes that Christopher has read with variable x
Christopher has read for more than 32 minutes corresponds with the inequality: x > 32 ."More than" is equivalent to "greater than", which is symbolized by ">".
Christopher has read for less than 32 minutes, corresponds with the inequality: x < 32 . "Less than" symbolized by "<".
Christopher has read for 32 minutes corresponds with the equality: X = 32. Here the amount of time is fixed, so it agrees with an equality instead of an inequality.

Step-by-step explanation:
Two bottles of water and three small bags of fruit cost a total of £2.55. If a bottle of water costs 15p more than a bag of fruit, what is the cost of a bag of fruit?
Answer:
The cost of a bag of fruit is 45p
Step-by-step explanation:
Let w be the number of water bottles.
Let f be the number of bags of fruits.
"Two bottles of water and three small bags of fruit cost a total of £2.55"
2w + 3f = 2.55
"a bottle of water costs 15p more than a bag of fruit"
w = 0.15 + f
Substitute the second formula to the first and solve.
2w + 3f = 2.55
2(0.15 + f) + 3f = 2.55
0.3 + 2f + 3f = 2.55
0.3 + 5f = 2.55
5f = 2.55 - 0.30
5f = 2.25
f = 2.25 ÷ 5
f = 0.45
Substitute to the second formula again and solve for w.
w = 0.15 + 0.45
w = 0.6
Now verify:
2w + 3f = 2.55
2(0.6) + 3(0.45) = 2.55
1.2 + 1.35 = 2.55
2.55 = 2.55 (Correct)

Enter the equation of the circle described below.
Center (0, 0), radius = 4
The standard equation of a unit circle is
x²+y²=1
So, if we want a radius of 4, we need to square it.
so we have x²+y²=16
Answer:
x^2 + y^2 = 16
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-0)^2 + (y-0)^2 = 4^2
x^2 + y^2 = 16

Which is a true statement about a 45-45-90 triangle?
O A. Each leg is 3 times as long as the hypotenuse.
O B. Each leg is 12 times as long as the hypotenuse.
O C. The hypotenuse is 3 times as long as either leg.
O D. The hypotenuse is v2 times as long as either leg.
The hypotenuse is √2 times as long as either leg of a 45-45-90 triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of ∠ACB = measure of ∠BAC = 45°
And , the measure of ∠ABC = 90°
So , the triangle is a 45-45-90 triangle
Now , the measure of the sides be AB = BC = 1 unit
And , From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
The measure of side AC ( hypotenuse ) = √ ( AB )² + ( BC )²
The measure of side AC ( hypotenuse ) = √ ( 1 + 1 )
The measure of side AC ( hypotenuse ) = √2 units
Hence , the measure of the hypotenuse of 45-45-90 triangle is √2 units

There is a group of $5$ children, where two of the children are twins. How many ways can I distribute $6$ identical pieces of candy to the children, if the twins must get an equal amount of candy?
Answer:
50
Step-by-step explanation:
Suppose that the kids get $x_1,x_2,x_3,x_4,x_4$ pieces of candy, respectively (each twin received $x_4$ pieces). Then we seek all quadruples $(x_1,x_2,x_3,x_4)$ satisfying
\[x_1+x_2+x_3+2x_4 = 6.\]We proceed by casework, based on the number of candies the twins receive.
If $x_4 = 0$, then there are 6 candies to distribute to 3 kids. This is like arranging 6 C's and 2 |'s (dividers), so there are $\binom{8}{2} = 28$ possible distributions.
If $x_4 = 1$, there are 4 candies remaining for the other 3 kids, so there are $\binom{6}{2} = 15$ possible distributions.
If $x_4 = 2$, there are 2 candies remaining, so there are $\binom{4}{2} = 6$ possible distributions.
If $x_4 = 3$, there are 0 candies remaining, for 1 possible distribution.
Adding all of these results from the separate cases, there are a total of
\[28 + 15 + 6 + 1 = \boxed{50}\].

Answer:
b= 3.5
s= 10.5
p=21
Step-by-step explanation:
b for brush
s for sketch book
p for paint set
b=1/3s
s= 1/2 p
b+s+p=37-2
1/3 s +s+2 s =35
1/3 s +s +2 s =35
10/3 s=35
s= 35*3/10
s= 10.5
b=1/3 s = 10.5/3 = 3.5
s= 1/2 p so p= 2s = 2( 10.5) = 21

21. If the area of the plane shape below is
36cm, find its height.
Answer:
4 cm
Step-by-step explanation:
The figure is a parallelogram with area (A) calculated as
A = bh ( b is the base and h the perpendicular height )
Here A = 36 and b = 9 , thus
9h = 36 ( divide both sides by 9 )
h = 4 cm
Answer:
Step-by-step explanation:
considering the breadth of the shape as 5cm and length as 9cm...
now... for finding the height of the plane shape...
we need to use the formula for area of a trapezium...
so. area of a trapezium = 1/2 x height x sum of parallel sides
we are given area of trapezium = 36cm^2
SO SUBSTITUTING THE EQUATION...
36 = 1/2 x height x (9+9)
height = 4cm
