Answer:
All statements are true, but if you try to reverse them they won't necessarily be true.
Let's try:
Square ⇒ Has 4 sides
But if something has 4 sides it doesn't mean it's a square (example: rectangle)
Angle is 80° ⇒ acute angle
But acute angle is any angle below 90°, not just 80° so the reverse isn't true.
x – 17 = 4 ⇒ x = 21
And if we reverse
x = 21 ⇒ x – 17 = 4
we see that it's true for either direction.
x = 7 ⇒ |x| = 7
But |x| = 7 doesn't mean that x has to be 7, x can also be -7, so the reverse isn't true.
x – 17 = 4, then x = 21

96 cm²
Step-by-step explanation:
The lateral surface area (A) is the sum of the areas of the 4 slant faces.
The faces are triangular with area [tex]\frac{1}{2}[/tex] bh , thus
A = 4 × [tex]\frac{1}{2}[/tex] × 8 × 6 = 2 × 48 = 96 cm²

4.3lb is more precise out of the answer choices of 4lb and 4.3lb because 4.3lb is an exact weight whereas 4lb could be rounded.
is {(3,4),(3,5),(4,4), (4,5)} a function
Answer:
No, it's not a function.
Step-by-step explanation:
This is not a function because the x-inputs repeat. It would be a function if each x-input was a different number, but the inputs 3 and 4 repeat twice. Therefore, this is not a function.
Answer:
This is NOT a function because you CANNOT have same x values twice.

A school choir needs to make T-shirts for its 75 members and has set aside some money in their budget to pay for them. The members of the choir decided to order from a printing company that charges $3 per shirt, plus a $50 fee for each color to be printed on the shirts. Select all the equations that could represent the relationship between the number of T-shirts ordered, the number of colors on the shirts(x), and the total cost of the order(y).
Answer:
y= 50x+ 225 \Step-by-step explanation:
Given that
the number of colors on the shirts(x), and
the total cost of the order(y).
since the number of colors is given as x
the total cost y can be represented as
y= 50x+ 75(3)
y= 50x+ 225
hence the total cost of 75 T-shirts is given by the model
y= 50x+ 225what is 2/5-5/6 is it negitive, positive, zero

What are each of the steps on solving 5x-2+ 3x=14. There are four steps and the choices are combine like terms, addition, subtraction, division, and distribution.
Answer:
5x - 2 = 3x = 14
8x -2 = 14
8x = 14 + 2
8x = 16
x = 2
Step-by-step explanation:
Answer:
add 5x and 3x then add -2 to 14. it should be 8x=12 then divide 8x and 12 by 8 and its 12/8 or simplify to 6/4 or 1 1/2 so combine like terms then addition then division i think :)

i need to find the area .
Answer:
105.12 ft^2
Step-by-step explanation:
Area of rectangle = 8 × 10 = 80 ft^2
Area of semicircle = 1/2π × 4^2
4 is the radius of the semicircle.
Since we use 3.14 to approximate π...
Area of semicircle = 1/2× 3.14 × 4^2 = 25.12
∴Total area = 25.12 + 80 = 105.12 ft^2
Answer: 105.12ft²
Step-by-step explanation: first we need to find the area of the rectangle with the formula: length × width so, 8ft × 10ft = 80 ft².
Now we can find the area of the semicircle with the formula: πr²÷ 2 so, (3.14 × 4²) ÷ 2 = 25.12ft². Now we need to calculate the area of the whole shape and we can do this by adding together our rectangle and semicircle so, 80ft + 25.12ft = 105.12ft².

To sketch the graph of y = (x - 3)2 + 2, the graph of y = x2 will need to be translated:
A 3 units to the left and 2 units up.
B 3 units to the right and 2 units up.
C 3 units to the left and 2 units down.
D 3 units to the right and 2 units down.
B
Step-by-step explanation:
since the formula requires you to subtract the x value, if the x value were to be negative(left) then the equation would be (x+3) because minus minus equals to plus but in this case it is (x-3) that means that the x value was positive.

Sarah's gross income last month was £1260.
She pays 20% tax on her gross income.
How much tax did Sarah pay last month?
ایا
Answer: 252
Step-by-step explanation:
The amount of tax paid by Sarah last month is £252.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that Sarah's gross income last month was £1260. She pays 20% tax on her gross income.
The tax amount is calculated by taking 20% of the gross income £1260.
Tax amount = 20% of £1260.
Tax amount = £1260 x 20 /100
Tax amount = £1260 / 5
Tax amount =£252.
Therefore, the amount of tax paid by Sarah last month is £252.

ABC is a triangle in which B = 90°. In each of
these, i draw and label a sketch, ii then calculate
b
the length of the third side of the triangle.
AB = 6 m, BC = 8 m
Step-by-step explanation:
You have to use pythagoras' theorem for this.
So AC is the length you want to find.
Pythagoras' theorem is a^2+b^2=c^2
In your triangle, AB=a, BC=b and AC=c
6^2+8^2=Ac^2
36+64= AC^2
100=AC^2
Square root both sides
10=AC
Therefore AC=10m
