surface are of sphere = πD²
SA = (3.14)(18.6 cm)^2
SA = 1086.3 cm²
Three bananas and two pears cost 95p.
Five bananas and three pears cost £1.51
Find the cost of ten bananas and ten pears.
Answer:
Cost of ten bananas and ten pears is £ 3.90
Step-by-step explanation:
As three bananas and two pears cost 95 p and five bananas and three pears cost £ 1.51 or 151 p ,
subtracting former from latter, we get
two bananas and one pear cost 151 p − 95 p = 56 p
and doubling four bananas and two pear cost 56 p × 2 = 112 p
Hence, one banana costs 112 p − 95 p = 17 p .
and two bananas cost 17 p × 2 = 34 p
and hence one pear costs 56 p − 34 p = 22 p
Hence cost of ten bananas and ten pears is
10 × 17 p + 10 × 22 p = 170 p + 220 p = 390 p = £ 3.90

Answer:
-28/45
Step-by-step explanation:
Step 1, the sign
When the fractions have an odd number of minus signs (1, not 0 or 2), the result will be negative. This knowledge lets you ignore the sign while you do the rest of the arithmetic. The appropriate sign is applied to the final numbers.
Step 2, the formula
The ratio (a/b)÷(c/d) is (ad)/(bc). There are several ways you can get there:
⇒ "invert and multiply" or "swap dot"
[tex]\dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\,\cdot\,\dfrac{d}{c}=\dfrac{ad}{bc} \quad\text{division is multiplication by the reciprocal}[/tex]
⇒ "numerators of a common denominator"
[tex]\dfrac{\left(\dfrac{a}{b}\right)}{\left(\dfrac{c}{d}\right)}=\dfrac{\left(\dfrac{ad}{bd}\right)}{\left(\dfrac{bc}{bd}\right)}=\dfrac{ad}{bc}[/tex]
⇒ "swapped denominators of a common numerator"
[tex]\dfrac{\left(\dfrac{a}{b}\right)}{\left(\dfrac{c}{d}\right)}=\dfrac{\left(\dfrac{ac}{bc}\right)}{\left(\dfrac{ac}{ad}\right)}=\dfrac{ad}{bc}[/tex]
The use of common numerators or common denominators is most often seen when the numerator or denominator of one fraction is a multiple of that in the other fraction. Example: (2/3)÷(1/6) = (4/6)÷(1/6) = 4/1 = 4
Step 3, reduce the result
Any of these fractions is reduced by cancelling common factors from numerator and denominator. Your fractions here don't have any common factors, so there is nothing to cancel.

The length of a rectangular tabletop is 18 inches more than the width. The perimeter is 244. What is the width of the tabletop?
Answer:
52 in.
Step-by-step explanation:
Let the width = x.
The length is x + 18.
perimeter = 2(L + W)
244 = 2(x + x + 18)
122 = 2x + 18
2x = 104
x = 52
The width is 52 in.
Answer:
length is 70 width 52

Suzy is shopping at a book sale.The table show prices for paperback books.
Answer:
6,9
Step-by-step explanation:
Got it right on edg
The ordered pair which is also on the graph is (6, 9).
What is the number pattern?A number pattern is a pattern in a series of numbers that represents the common relationship between the numbers.
Suzy is shopping at a book sale.
We can see from the table that when books( x) is 2 then the value of y is 3.
Similarly, x = 4 then y = 6
then we can say that the value of y is the addition of half of the value of x in itself.
So, according to the number pattern;
if we take x = 6
Then 6 + 3 = 9
y = 9
Thus, The ordered pair which is also on the graph is (6, 9).

We have a side that is opposite our angle,
and we have the hypotenuse. Which ratio
will we use?
Answer:
Sine
Step-by-step explanation:
Using the acronym SOHCAHTOA, we can see that Sine (S) should be used.
SOH represents Sine, Opposite, Hypotenuse.
Since we are only given the opposite side and hypotenuse, the sine ratio should be used, which is opposite / hypotenuse
So, sine will be used.

find the size of angle X.
The size of angle x is 115.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
From the figure,
The whole complete angle is 360.
This means,
164 + 81 + x = 360
Solve for x.
164 + 81 + x = 360
245 + x = 360
x = 360 - 245
x = 115
Therefore,
The size of angle x is 115.

Find all angles, 0°< A<360°, that satisfy the equation below, to the nearest tenth
of a degree (if necessary).
3 tan A+75 = 0
Answer:
143.3 degrees and 323.3 degrees
Step-by-step explanation:
Given the equation
3tanA +√5 = 0
3tanA = -√5
tanA =-√5/3
tanA = (-0.7454)
A = arctan(-0.7453)
A = -36.699
Since tan is negative in 2nd and 4th quadrant
A = 180 - 36.699
A = 143.3 degrees
In the fourth quadrant
A = 360 - 36.699
A = 323.3degrees
Hence the value of A that satisfies the equation are 143.3 degrees and 323.3 degrees
