Step-by-step explanation:
1. (x + 2) = 0 gives us x = -2 = x coordinate of vertex; and
the -1 at the end gives us the y coordinate.
Move the vertex of the parabola to the point (-2,-1)
2. The -4 in front of the (x+2)² gives the direction and stretch of the parabola. FROM the Vertex, position the other point Down 4 and Right 1 (at (1,-5)).

Every day, Garrett's burrito stand uses 1 7/10 bags of tortillas. How many days will 8 1/2 bags of tortillas last?
Answer: 5 days.
Step-by-step explanation: To solve this problem, we first need to convert 1 7/10 bags of tortillas to a decimal number. We can do this by dividing the numerator of the fraction (7) by the denominator (10) and adding the result to the whole number (1) to get 1 + 7/10 = 1.7 bags of tortillas.
Next, we can divide the number of bags of tortillas that Garrett's burrito stand uses per day (1.7 bags) into the total number of bags of tortillas that are available (8.5 bags) to find out how many days the tortillas will last: 8.5 bags / 1.7 bags/day = 5 days
Therefore, the 8 1/2 bags of tortillas will last for 5 days.

The perimeter of a triangle is 58 cm. The triangle is isosceles, but if its base were lengthened by 4 cm and each leg were shortened by 7 cm, then it would be equilateral. Find the base of the original
triangle.
A. 12 cm
B. 11 cm
C. 23 cm
D. 16 cm
The base of the original triangle is 12 centimetres.
How to find the base of the original triangle?A triangle is a polygon with three sides. The perimeter of a triangle is 58 cm. The triangle is isosceles.
An isosceles triangle is a triangle with 2 sides equal to each other and two angles equal to each other.
Therefore, let's find the base of the original triangle when the base were lengthened by 4 cm and each leg were shortened by 7 cm,
Hence,
let
x = length of legs
y = length of the base
Therefore,
2x + y = 58
Hence,
y + 4 = x - 7
x - y = 11
2x + y = 58
x - y = 11
3x = 69
x = 69 / 3
x = 23
-y = 11 - 23
-y = -12
y = 12
Therefore,
base of the original triangle = 12 cm

You are a construction worker who is laying down concrete drainage pipes. Each pipe is 5 feet long and 3 inches thick, and has an outside diameter of 6.5 feet. You lay down 4 drainage pipes end to end.
At any given time, what is the volume of water that passes through the 4 drainage pipes at half capacity? Round the answer to the nearest tenth of a cubic foot.
141.3
165.8
282.6
306.6
565.2
Answer:
Volume = 282.6 ft.²
Step-by-step explanation:
Volume: V = πr²h
Step 1: The answer needs to be in cubic feet, so convert all units to feet
1. 3 ft./12 in. = 0.25 ft.
Step 2: Subtract 0.5 ft from 6.5 ft to find the actual diameter of the pipe that the water will be passing through
2. 6.5 ft. - 0.5 ft. = 6 ft.
Step 3: Plug 3 ft. (radius), 3.14 for π, and 5 ft for h
3. V = (3.14)(3 ft.)²(5 ft.)
Step 4: Solve for the V (volume)
4. V = (3.14)(9 ft.)(5 ft.) → V = (28.26)(5) → V = (28.26)(5) → V = 141.3 ft.²
Step 5: Divide 141.3 by 2, since we want half the capacity
5. 141.3 ft.²/2 = 70.65 ft.²
Step 6: Multiply 70.65 by 4 since we want the total volume of water passing through four pipes
6. 70.65 ft.² ∙ 4 = 282.6 ft.²

When loaded with bricks, a lorry has a mass of 11600 kg. If the mass of the bricks is three times that of the empty lorry, find the mass of the bricks.
Answer:
8700kg
Step-by-step explanation:
b = mass of bricks
l = mass of lorry
b+l = total mass = 11600kg
b = 3l ==> l = b/3
substitute: b + b/3 = 11600
multiply every term by 3 to get rid of denominator: 3b + b = 34800
simplify and solve: 4b = 34800 ==> b = 8700
check: l = 8700/3 = 2900
2900 + 8700 = 11600? YES

Answer:
21
Step-by-step explanation:
PEMDAS : Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.
First, we want to deal with the parenthesis within the parenthesis.
(4.6/2) = 2.3
Rewrite it into the equation.
[3 * 2.3] + 14.1 = ?
Now, do the work in the parenthesis again.
[6.9] + 14.1 = ?
There isn't anymore parenthesis, exponents, or multiplication/division, so we move onto addition now and add both terms.
6.9 + 14.1 = 21
? = 21
The answer is 21.

During a test, 3 out of 100 cars selected at random were found to be defective. Use this ratio to estimate the number of defective cars if 1,500 cars are tested.
There are 45 defective cars if 1,500 cars are tested.
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities.
Given that;
During a test, 3 out of 100 cars selected at random were found to be defective.
Now,
Since, During a test, 3 out of 100 cars selected at random were found to be defective.
Let number of defective cars if 1,500 cars are tested = x
So, By definition of ratio, we get;
⇒ 3 / 100 = x / 1,500
Solve for x as;
⇒ 3 × 1500 / 100 = x
⇒ 3 × 15 = x
⇒ x = 45
Thus, There are 45 defective cars if 1,500 cars are tested.

Your redecorating your bedroom, and you want to put in a dressing table. The wall where you want to put it measures 4.7m. There is also a cupboard door on this wall, which takes up 410mm. The dressing table you like is 123cm wide. Once you've bought the dressing table , how much space on the wall, do you have left, not including the cupboard doors? I need this working out in metres please.
Answer:
3.06 meters
Step-by-step explanation:
The first thing you want to do, since we are working with different units here, is find out how many centimeters make a meter... and so on.
1cm = 0.01m
1mm = 0.001m
123cm = 1.23m (Dressing table)
410mm = 0.41m (Cupboard door)
Now all we need to do is subtract.
We can add the two numbers together or (If you prefer) subtract separately.
1.23 + 0.41 = 1.64
Now subtract that number from the measurement of the wall:
4.7 - 1.64 = 3.06
The amount of space left is 3.06m.

Is the sum of 3.04 and √20 rational or irrational? Explain.
Answer:
Irrational
Step-by-step explanation:
A rational number can be expressed as p/q where p and q are integers
3.04 is rational since it can be expressed as 304/100
√20 is not rational. √20 = √(4·5) = √4·√5 = 2√5
While 2 is a rational number, √5 is irrational since 5 is a prime number and square roots of primes are not rational
An irrational number multiplied by a rational number is irrational so √20 is irrational
An irrational number added to a rational number results in an irrational number.
So 3.04 + √20 is irrational

Define solutions of linear equations.The collection of variable values in linear equations that yields all feasible solutions is referred to as the solution of a linear equation. In order to describe real-world issues, linear equations contain unknown values in the form of one or more variables. The collection of values for each variable in a system of linear equations is referred to as the solution set.
Consider the equation,
7x - 5y = 28
Now put the values from options, the pair values at which LHS = RHS that will be the solution to the equation.
Put x = 77, y = 9 in the equation

Answer: D
Step-by-step explanation:
The parent function abs(x) is a V, similar to graph B.
When it is multiplied by a negative number then it reflects across the Y axis, and if the number is greater than 1, then the graph is horizontally compressed (like you're squishing the sides together, closer to each other). If the number is less than 1, either decimals or a fraction, then it is stretched (like you are pulling the sides away from each other and they are getting wider).
In this case you are multiplying abs(x) by 4, which is greater than 1 so it is compressed by a factor of 4, and then multiplying it by a negative, which reflects it across the y axis.
