Answer:
Step-by-step explanation:
let the first angle be 5x
second be 4x
and third be 1x
as we know that by adding all the sides of triangle we get 180°
therefore ,
5x+4x+1x=180°
10x=180°
hence ,
x=18°
first angle - 18*5 = 90°
second angle - 18*4=72°
third angle - 18°
HOPE THIS HELPS YOU !!!
Answer:
18°, 72°, 90°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the parts of the ratio, 5 + 4 + 1 = 10 parts
divide to find the value of one part of the ratio
180° ÷ 10 = 18° ← value of 1 part of the ratio , thus
5 parts = 5 × 18° = 90°
4 parts = 4 × 18° = 72°
Thus the angles of the triangle are 18°, 72° and 90°

What is two hundred sixty-five thousandths in standard form?
Answer:
10^-1*2.65
Step-by-step explanation:
two hundred sixty-five thousandths= 0.265
We need a number between 1 and 10, to do the multiplication in standard form, so 0.265 turns into 2.65.
Because 2.65 becomes, smaller we use a negative power. We only move the decimal place once to the left, so we would multiply 2.65 by 10^1.
10^-1*2.65=0.265
The standard form of two hundred sixty-five thousandths is 265 × 10⁻³.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given that,
Two hundred sixty-five = 200 + 65 = 265
Now,
Thousandths mean we need to divide it by thousand
So,
⇒ 265/1000
⇒ 265/10³
By the law of indices
⇒ 265 × 10⁻³
Hence "The standard form of two hundred sixty-five thousandths is 265 × 10⁻³".

if f(x)=7(x-1)+8, what is the value of f(1)
Answer:
8
Step-by-step explanation:
f(1)=7(1-1)+8
f(1)=7(0)+8
f(1)=0+8
f(1)=8
The value of f(1) if f(x)=7(x-1)+8 is 8
From the question,
The given function is f(x)=7(x-1)+8
We are to determine the value of f(1) if f(x)=7(x-1)+8
To do this, we will put the value x =1 into the function
That is,
f(x)=7(x-1)+8 becomes
f(1)=7(1-1)+8
The, we get
f(1) = 7(0) + 8
f(1) = 7×0 + 8
f(1) = 0 + 8
∴ f(1) = 8
Hence, the value of f(1) if f(x)=7(x-1)+8 is 8

Round to the nearest tenth.
4.8367
Answer:
Number = 4.8367
Rounded to the nearest tenth means, rounded to the number after the decimal point.
We will have to round down because the hundredth is less than 5
So, we get,
4.8367 becomes, 4.8
Therefore 4.8367 rounded to the nearest tenth = 4.8

The number 4.8367, when rounded to the nearest tenth, becomes 4.8
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
if the right sided digit to the digit where we've to round off is < 5, we keep it same and make all right sided values 0, and if the right sided digit is > 5, then we make it increase by 1 and rest of the right sided digits become 0. If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
Rounding to the nearest tenth means rounding the first place to the right of the decimal point.
The given number is 4.8367
The digit on the right of the decimal point is 8. On the right of that, there is 3, which is < 5, so the first right digit on right of the decimal point, after rounding, will have no change,and rest of the numbers from the right first place of the decimal point will get trimmed off.
Thus, we get:
4.8367 → 4.8 (after rounding to the nearest tenth)
Thus, the number 4.8367, when rounded to the nearest tenth, becomes 4.8

Write an equation in slope-intercept form that would have infinitely many solutions in a system of equations with 5x+2y=8
Answer:
y=5/2x-4
Step-by-step explanation:
got it right on my math assignment
The required equation of line in the slope-intercept form will be [tex]y=-\dfrac{5}{2}x+4[/tex].
The given equation of line is [tex]5x+2y=8[/tex].
It is required to write the equation of a line in the slope-intercept form which has infinitely many solutions in the system of equation with the given line.
The system of equations has infinitely many solutions when the equations are the same or all of their coefficients are in the same ratio.
So, the other equation could be,
[tex]k(5x+2y)=8k\\5x+2y=8[/tex]
Now, the equation in slope-intercept form can be written as,
[tex]5x+2y=8\\2y=-5x+8\\y=-\dfrac{5}{2}x+4[/tex]
where the slope of the line is [tex]-\dfrac{5}{2}[/tex] and the y-intercept is 4.
Therefore, the required equation of line in the slope-intercept form will be [tex]y=-\dfrac{5}{2}x+4[/tex].
