HELP LOLL
Answer:
RT=108
Step-by-step explanation:
Consider ΔQST:
Use pythagorus's theorem.
a²=b²+c²
QS²=QT²+ST²
53²=QT²+28²
2809-784=QT²
QT=√2025=45
Consider ΔQRT:
Use pythagorus's theorem.
a²=b²+c²
QR²=QT²+RT²
117²=45²+RT²
13689-2025=RT²
RT=√11664=108

The sum of a two digit number and the number obtained by interchanging the digits is 132. If the two digits differ by 2, find the number
Answer:
A two-digit number can be written as:
a*10 + b*1
Where a and b are single-digit numbers, and a ≠ 0.
We know that:
"The sum of a two-digit number and the number obtained by interchanging the digits is 132."
then:
a*10 + b*1 + (b*10 + a*1) = 132
And we also know that the digits differ by 2.
then:
a = b + 2
or
a = b - 2
So let's solve this:
We start with the equation:
a*10 + b*1 + (b*10 + a*1) = 132
(a*10 + a) + (b*10 + b) = 132
a*11 + b*11 = 132
(a + b)*11 = 132
(a + b) = 132/11 = 12
Then:
a + b = 12
And remember that:
a = b + 2
or
a = b - 2
Then if we select the first one, we get:
a + b = 12
(b + 2) + b = 12
2*b + 2 = 12
2*b = 12 -2 = 10
b = 10/2 = 5
b = 5
then a = b + 2= 5 + 2 = 7
The number is 75.
And if we selected:
a = b - 2, we would get the number 57.
Both are valid solutions because we are changing the order of the digits, so is the same:
75 + 57
than
57 + 75.

Which number line shows all the values of that make the inequality - 3x +1 < 7 true?
Answer:
D
Step-by-step explanation:
First, simplify the equation.
-3x+1<7
-3x<6
x>-2 (the sign flips because you are dividing by negative)
> means x is greater than -2 so the line will go towards the right.
Because the sign is >, the dot is open.
The number line C shows all the values for the inequality -3x + 1 < 7.
What is an inequality?'In Mathematics, the relationship between two values that are not equal is defined by inequalities. Inequality means not equal.'
According to the given problem,
Given inequality = -3x + 1 < 7
⇒ -3x < 7 - 1
⇒ -3x < 6
⇒ -x < 2
⇒ x > -2
Interval notation of the values of x = ( -2 , ∝ )
Number line C graphs all the values of x, which is greater than -2 and extends up to infinity.
Hence, we can conclude number line C shows all the values of x in the interval (-2 , ∝).

the base of a triangular field is 22m. The area of the field is 550m2 . find the height
Step-by-step explanation:
Area of triangular prism =1/2 ×base×height
550=1/2×22×h
h=550/11
h=50m
hope it helps.
Answer:
height = 50 m
Step-by-step explanation:
Area of a triangle = 1/2* base * height
550 = 1/2 * 22 * height
550 = 11 * height
therefore, 550/11 = height
therefore, height = 50 metres
The sum of the ages of a boy and his mother is 48. If the mother is three more than twice the boy’s age, find the difference in the ages of the boy and his mother.
Answer:
18 years
Step-by-step explanation:
let the boy's age my x and mother's age be y
x+y=48
y=3+2x which can also be written as 2x-y=-3
on solving both the equations,
you will get x=15 and y=33
so son's age is 15 years and mom's age is 33 years and the difference between their ages is 18

what is the value of x , if y = 2
in the given equation ;
5x + 2y = 9
Answer:
Solve the system of equations.
x = 1
y = 2
Step-by-step explanation:
Hope it is helpful....
[tex]5x + 2y = 9[/tex]
with given condition where y = 2.
Therefore, substitute the value of y in the equation.
[tex]5x + 2(2) = 9 \\ 5x + 4 = 9[/tex]
Solve the equation for x-term.[tex]5x = 9 - 4 \\ 5x = 5 \\ x = \frac{5}{5} \longrightarrow \frac{1}{1} \\ x = 1[/tex]
Check the answer by substituting both x-value and given y-value in the equation.[tex]5x + 2y = 9 \\ 5(1) + 2(2) = 9 \\ 5 + 4 = 9 \\ 9 = 9 \longrightarrow \bf{true} \: \green{ \checkmark}[/tex]
Hence, the value of x is 1.

Podłoga w łazience ma kształt kwadratu o boku 3 m. Ile płytek terakoty o wymiarach 10cm x 20cm wypełni podłoge ?
Odpowiedź:
450 płytek
Wyjaśnienie krok po kroku:
Jeśli się uwzględni:
Kształt łazienki = kwadrat
Powierzchnia kwadratu = s²; gdzie, s = długość boku
Długość boku, s = 3m
Powierzchnia łazienki = 3² = 9m²
Wymiar płytek z terakoty = 10cm * 20cm
Powierzchnia płytek = 10 * 20 = 200 cm²
1 m² = 100 * 100 = 10000 cm²
W związku z tym,
Powierzchnia łazienki:
9m² = (10000 * 9) = 90000 cm²
Liczba płytek:
Powierzchnia łazienki / Powierzchnia jednej płytki
90 000 cm² / 200 cm²
= 450 płytek
