Which equation is a related fact to 60 ÷ 10 = ∎? A) ∎ = 10 × 60 B) ∎ × 10 = 60 C) 10 = ∎ × 60 Please help me.
Answer:
Hey! here is the answer!
Step-by-step explanation:
C! 10 = ∎ × 60
i know this becuase i did the equation in reverse, then used my calculator to make sure all the numbers added up.
Answer: B)
Step-by-step explanation:
First we need to find the value of the black sqaure. The value of the black square is 6 because 60 / 10 = 6. A) cannot be the answer because 6 does not equal 60. C) cannot be the answer because 10 does not equal 360. The only answer can be B) because 6 x 10 does equal 60.
If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Answer:
$36.38
Step-by-step explanation:
If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Given data
Tax= 7%
Cost = $34
Let us solve for the amount of tax
=7/100*34
=0.07*34
=2.38
Hence the total is =2.38+34
=$36.38

Write an equivalent expression. -2(7+5g)
Answer:
-2(7) + -2(5g)
Step-by-step explanation:
Using the distributive property we can confirm that:
-2(7) + -2(5g) = -2(7+5g)
Answer:
−14−10g
Step-by-step explanation:
First, solve the product:
-2 ⋅ 7 - 2 ⋅ 5g
Multiply -2 times 7 to -14.
So, the equivalent expression would be:
-14 - 2 ⋅ 5g = -14 - 10g
-14 - 10g
What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
[tex]y = - 7[/tex]
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7
Hope this helps :)

Answer:
0
Step-by-step explanation:
find mean of given numbers u notice that mean is actually 6 so no number is required to be included
Answer:
4. x = 35. Number 6 should be includedStep-by-step explanation:
Mean is the average
4.
Data given:
14, 6, 2x, 8, 10, 4The mean is
mean = sum of the data / number of data(14 + 6 + 2x + 8 + 10 + 4)/6 = 842 + 2x = 6*82x = 48 - 422x = 6x = 35. Let the added number is x, then the mean is:

Christian is planning a vacation and finds an airplane ticket that cost 180$. He found a promo code offering 17% off. Write a single algebraic expression that can be used to find the cost of Christian’s ticket after the discount.
Answer:
83/100 x 180
Step-by-step explanation:
We have to find the cost of the ticket after the discount.
100% - 17%= 83%
83% of the total percentage of the original price that he needs to pay.
So we do:
83/100 x 180
So, this would be the expression.
Hope this helps!:)
5. Suppose you invested PHP 25,000 at a simple interest at a rate of 2.5%, how much will be your investment after
10 years? a. PHP 43,750.00
C.PHP 45,730.00
b. PHP 31,250.00
d. PHP 47,350
Answer:
b. PHP 31,250.00
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = PHP 25,000
Rate = 2.5%
Time = 10 years
Simple interest = principal × rate × time
= PHP 25,000 × 2.5% × 10
= 25,000 × 0.025 × 10
= 6,250
Simple interest = PHP 6,250
Investment after 10 years = principal + simple interest
= PHP 25,000 + PHP 6,250
= PHP 31,250
Investment after 10 years = PHP 31,250

Find the area of equilateral triangle with side a. Please answer with completely simplified exact values. Answer: A = sq. Units
Solution :
It is given that the length of a side of a triangle is given by 'a'.
It is an equilateral triangle.
So the three sides will be of equal length and is a, a, a units.
Now the semi perimeter of the equilateral triangle is given by :
[tex]$S=\frac{a+a+a}{2}$[/tex]
[tex]$=\frac{3}{2}a$[/tex]
Therefore, using the Heron's formula, we can find the area of the equilateral triangle.
Area of the equilateral triangle is given by :
[tex]$A =\sqrt{S(S-a)(S-a)(S-a)}$[/tex]
[tex]$A =\sqrt{\frac{3a}{2}\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)}$[/tex]
[tex]$A=\frac{\sqrt3}{4}a^2$[/tex] square units.

Answer:
204
Step-by-step explanation:
The area of the top triangle = 5*12/2 = 30
The area of the bottom triangle = 30
The hypotenuse of the top triangle is
5^2 + 12^2 = hypotenuse^2
25 + 144 = hypotenuse^2
169 = hypotenuse squared.
hypotenuse = sqrt(169)
hypotenuse = 13
Now the back face = 13 * 8 = 104
The area of the left side rectangular face = 5*8 = 40
The total area = 30 + 30 + 104 + 40 = 204

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)
Answer:
4,3cm
Step-by-step explanation:
Passo 1
Um losango tem 2 diagonais, cujos comprimentos não são iguais
Temos que encontrar o comprimento da segunda diagonal
A fórmula é dada como:
Área de um losango = 1/2 (d1 × d2)
Área do losango = 12 cm²
d1 = Comprimento da primeira diagonal = 8cm
d2 = Comprimento da segunda diagonal = x
12 = 1/2 (8 × x)
12 = 1/2 (8x)
12 = 4x
x = 12/4
x = 3cm
O comprimento da segunda diagonal = 3 cm
Passo 2
A fórmula do comprimento da lateral de um losango é dada como:
s = √d1² + d2² / 2
d1 = 8cm
d2 = 3 cm
s = √8² + 3² / 2
s = √64 + 9/2
s = √73 / 2
s = 8,5440037453 / 2
s = 4,2720018727 cm
Aproximadamente = 4,3 cm
