Answers
Answer:
300ft^2
Step-by-step explanation:
Total surface area = Area of base + (1/2) x perimeter of base x slant height
Area of base = length² = 10 x 10 = 100
Perimeter of base = 2 ( length + breadth)
2 x 20 = 40
slant height = 10
100 + (1/2) x 40 x 10 = 300 ft^2

Which table shows a proportional relationship?
Answers
Answer:
Table D (the last option)
Step-by-step explanation:
The table that shows a proportional relationship between x and y is the table where the value of y/x for all pair of values on the table are the same and equal.
k = y/x
Thus, in table D,
-8/1 = -24/3 = -32/4 = -48/6 = -8
This shows that the table represents a proportional relationship.
PLEASE HELP ASAPPPPP Find the value of x for mAB= 27° and mCD= 49°. The figure is not drawn to scale
Answers
Answer:
Step-by-step explanation:
The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.
It is A.
38 degrees.
The measure of x is (a) 38 degrees
The given parameters are:
[tex]mAB = 27^o[/tex]
[tex]mCD = 49^o[/tex]
The measure of x, is the average of angles AB and CD.
So, we have:
[tex]x = \frac{mAB + mCD}{2}[/tex]
Substitute known values of AB and CD in the above equation.
So, we have:
[tex]x = \frac{27^o + 49^o}{2}[/tex]
Add 27and 49
[tex]x = \frac{76^o}{2}[/tex]
Divide 76 by 2
[tex]x = 38^o[/tex]
Hence, the measure of x is (a) 38 degrees

the sum of two numbers is 52. If one number is 76 times the second number, then find the largest number out of the two.
Answers
Answer:
The larger number is 51.3. (to 3 s.f.)
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
Given that the sum of the 2 numbers is 52,
x +y= 52 -----(1)
One number is 76 times the second number. Since we have made y to be the larger number,
y= 76x -----(2)
Substitute equation (2) into (1):
x +76x= 52
Simplify:
77x= 52
Divide both sides by 77:
x= 52 ÷77
[tex]x = \frac{52}{77} [/tex]
x= 0.675 (3 s.f.)
Substitute the value of x into (2):
[tex]y = 76( \frac{52}{77} )[/tex]
[tex]y = 51 \frac{25}{77} [/tex]
y= 51.3 (3 s.f.)

in this case you will solve using foil method

A 2-kilogram bag of potting soil costs $1.96. What is the unit price?
Answers
Answer:
The unit price is $0.98
Answer:
98¢
Step-by-step explanation:
The unit price of an item is the price of one unit. In this case, this would be the price of a single kilogram.
To find the unit price, we'll divide the given price by the amount of units it is for. So, divide 1.96 by 2.
1.96 ÷ 2 = unit price
0.98 = unit price
This means the price of a single kilo of potting soil is $0.98. The unit price of the potting soil is 98 cents.

find the slope, and in y=mx+b form
Answers
9514 1404 393
Answer:
slope: 1y = x +6Step-by-step explanation:
The slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
Using the first two table entries, this is ...
m = (5 -4)/(-1 -(-2)) = 1/1
m = 1
The y-intercept can be found using the formula ...
b = y1 -m·x1
b = 4 -(1)(-2) = 6
Then the slope-intercept equation is ...
y = mx + b
y = x + 6
The slope is 1; the equation is y = x+6.
Answer:
the answer is
slope:1
y=x+6

James and Elizabeth buy some clothes,

Elizabeth buys 3 shirts and 2 jumpers. She pays £29.
Assume that each shirt has the same cost and that each jump
Work out the cost of one shirt and the cost of one jumper.
You must show your working.
Answers
Answer:
Jumper, y = 172
Shirt, x = - 105
Step-by-step explanation:
Let :
Shirt = x
Jumper = y
5x + 4y = 163 - - (1)
3x + 2y = 29 - - - (2)
Multiply (1) by 3 and (2) by 5
15x + 12y = 489 - - - (3)
15x + 10y = 145 - - - (4)
Subtract :
12y - 10y = 489 - 145
2y = 344
y = 344 / 2
y = 172
Put y = 172 in (3)
15x + 12(172) = 489
15x + 2064 = 489
15x = 489 - 2064
15x = - 1575
x = - 105
The values ;
Jumper, y = 172
Shirt, x = - 105

Answers
Answer:
Their present ages are:
Her daughter's age = 12 years Women's age = 36 yearsStep-by-step explanation:
Given that:
A woman is thrice as old as her daughter. 12 years hence, she will be twice as old as her daughter.To Find:
Their present ages.Let us assume:
Her daughter age be x. Women's age = 3xAfter 12 years:
Her daughter's age = x + 12Women's age = 3x + 12Finding their present ages:
According to the question.
⇒ 3x + 12 = 2(x + 12)
⇒ 3x + 12 = 2x + 24
⇒ 3x - 2x = 24 - 12
⇒ x = 12
Their present ages:
Her daughter's age = x = 12 years Women's age = 3x = (3 × 12) = 36 yearsAges after 12 years:
Her daughter's age = x + 12 = (12 + 12) = 24 years Women's age = 3x + 12 = (3 × 12) + 12 = (36 + 12) = 48 years1. One Friday, Mrs. Akiko called out 25 students to take the WIDA test. Eighteen students showed up. How many students did not take the test?
