The next place value on the right should be used to round a number to the closest tenth (the hundredths). Simply take away all the digits to the right if it's 4 or fewer. Remove all the digits to the right after adding 1 to the digit in the tenths position if the number is five or above.
To what decimal place do you round?
Examine the hundredth number to determine the decimal number's nearest tenth. Add one to the tenth value if the number is more than 5. Remove all the numbers that are present after the tenth place if the value is less than 5, but keep the tenth place value in place otherwise. As an illustration, if you want to round up to the nearest.

Multiply. [−3⋅914]⋅[(−0.1)⋅(−28)]
Answers
The solution to the given expression is 7,677.6.
This is a question of multiplication.
Multiplication
In mathematics, multiplication is used as a method of finding the product of two or more numbers. It is one of the arithmetic operations, like addition, subtraction and division that we use in everyday life. The major application we can see in multiplication tables.
In arithmetic, the multiplication of two numbers is represented by the repeated addition of one number with respect to another.
Given expression:-
[−3*914]*[(−0.1)*(−28)]
We have to find the solution of the given expression.
We have,
-3*914 = -2742
(-0.1)*(-28) = 2.8
Hence, we can write,
[−3*914]*[(−0.1)*(−28)] = (-2742)*(2.8)
(-2742)*(2.8) = 7,677.6

Find the equation of a parabola with a focus at (-2,-3) and a directrix at y = -5
Answers
The equation of a parabola with a focus at (-2,-3) and a directrix at y = -5 is y = 1/7(x + 2)^2 - 8/7 vertex is (2, -8/7)
What is Parabola?
A parabola is the location of a moving point whose distance from a given focus point and directrix line, respectively, is always constant.
let's keep it simple: (x, y). Focus is on (7,5)
When the separation from focus is
[tex]\sqrt{(x - (-2)^{2}) + (y - (-3)^{2} ) }[/tex] . Its distance from directrix y = -5 i.e.
y + 5 = |y + 5|^2
Hence, equation of parabola:
(x - (-2))^2 + (y - (-3))^2 = |y + 5|^2
or, (x + 2)^2 + (y + 3)^2 = |y + 5|^2
x^2 + 4x + 4 + y^2 + 3y + 9 = y^2 + 10y + 25
or, x^2 + 4x + 13 + y^2 + 3y = y^2 + 10y + 25
x^2 + 4x - 12 = 7y
y = (x^2 + 4x - 12)/7
y = 1/7(x^2 + 4x +4 - 4) - 12/7
y = 1/7(x + 2)^2 - 12-4/7
y = 1/7(x + 2)^2 - 8/7
Hence, parabola's equation is y = 1/7(x + 2)^2 - 8/7 vertex is (2, -8/7)

HIghschool Alegbra 1
Answers
Expression ( w+4)(w + 7) represent the total area of the garden and walkway.
What is Area of Rectangle?The area of Rectangle is length times of width.
Given that the width of the garden, in feet be w.
The length is 3 feet longer than its width, hence: w + 3
The entire garden is surrounded by a 2-foot-wide cement walkway. Therefore:
garden and walkaway length= (w + 3) + 2 + 2 = w + 7
garden and walkaway width = w + 2 + 2 = w + 4
The area of garden and walkaway

The length of a car is 4.2m,correct to 1 decimal place. Write down the upper bond and the lower bond of the length of this car.
Answers
Answer:
The upper pound is 4.25 m and the lower bound is 4.15 m
4.15 m ≤ 4.2 m < 4.25 m
Step-by-step explanation:
Let us solve the question
∵ The length of the car corrected to 1 decimal place
→ 1 decimal place means tenth
∴ It corrected to the tenths place which is 0.1
→ Divide it by 2
∵ 0.1 ÷ 2 = 0.05
∴ The limit is 0.05 m
→ To get the lower bound subtract 0.05 from the length of the car
∵ The length of the care is 4.2 m
∴ The lower bound = 4.2 - 0.05
∴ The lower bound = 4.15 m
→ To get the upper bound add 0.05 to the length of the car
∵ The length of the care is 4.2 m
∴ The upper bound = 4.2 + 0.05
∴ The upper bound = 4.25 m
∴ 4.15 m ≤ 4.2 m < 4.25 m
∴ The upper pound is 4.25 m and the lower bound is 4.15 m

if the flow rate in an artery has been reduced to 8.5% of its normal value by a blood clot and the average pressure difference has increased by 20.5%, what percent of the original is the radius of the reduced artery?
Answers
Percent of the original is the radius of the reduced artery is 0.070 times the original radius.
Given that,
A blood clot has lowered the flow rate in an artery to 8.5% of its usual value, and the average pressure difference has increased by 20.5%.
p1 = 8.5 % ,
p2 = 20.5 %
The equation is using here is From Poiseuille's equation
Q = \Delta p \pi r4 / 8 \eta L
now
Q1 = \Delta p1\pi r14 / 8 \eta L
and
Q2 = \Delta p2\pi r24 / 8 \eta L
Q1 = \Delta p1\pi r14 / 8 \eta L / Q2 = \Delta p2\pi r24 / 8 \eta L
Q1 / Q2 = \Delta p1 ro4 / \Delta p2 r24
r24 = ( 0.085 Q1 / Q1 ) ( \Delta p1 / \Delta p1 + 0.20 \Delta p1 ) ro4
r24 = 0.085 X ( 1 / ( 1 + 0.20 ) ro4
r2 = 0.070 ro
As a result, the shortened artery's radius is 0.070 times its original radius, or percent of the original.

A triangle's interior angles always add up to 180°, whereas its exterior angles are equal to the sum of the two interior angles that are not adjacent to it. Another method for calculating a triangle's exterior angle is to subtract the angle of the vertex of interest from 180°.
A protractor is the most convenient tool for measuring angles. If you don't have a protractor, you can use the basic geometric principles of triangles to determine the size of an angle. To solve the equations, you'll need a scientific calculator.

1) A translation of 3 units down, option D.
2) The vertex moves 3 units down.
3) The new range is y ≥ -3, correct option is C.
Which transformation is applied?For a function f(x) a vertical shift of N units is written as:
g(x) = f(x) + N
In this case, we have:
f(x) = |x|
h(x) = |x| - 3
Then h(x) = f(x) - 3
This is a shift of 3 units down, the correct option is D.
How is the vertex affected?
The vertex is translated 3 units down, like the whole graph of the function.
How is the range affected?
The vertex defines the minimum of the range, so if the vertex goes 3 units down, then the range also does, the new range will be:
y ≥ -3.

Answers
Given that the chosen kid gave a joy response, the probability that the student belongs to the age range of 6 to 8 years is 28/89.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.So, the likelihood that a pupil is between the ages of 6 and 8 can be calculated using the techniques below:
Step 1: 89 pupils out of a possible 200 answered with joy, as shown in the table.Step 2 - It is also stated that there were a total of 28 students in the age range of 6 to 8 years who answered positively.Step 3 - Accordingly, the likelihood that the pupil belongs to the 6 to 8-year-old age range is:P = 28/89
