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

The ratio of male to female students in a junior high
school is 13:17. Find the total population of the
school if there are 715 male students.
plsss.......answer
the total no of population=1650
13:17 first add the two numbers 13+17=30
then 13/30×y =715 , i make 13 at the numerator because it's males ratio
after that 30/13×13/30y =715 ×30/13
y =715×30/13
y =1650
after u find the total no it's simple to find the no of females
17/30×1650=935

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

Madeline is going to invest in an account paying an interest rate of 4.4% compounded
annually. How much would Madeline need to invest, to the nearest ten dollars, for
the value of the account to reach $16,600 in 12 years?
Answer:
$9540
Step-by-step explanation:
A = P(1 + r)^t
16600 = P(1.044)^12
P = 16600/(1.044)^12
P = $9,543.64

Five less than twice the value of a number is equal to three times the quantity of
four more than one-half the number. What is the
number?
a. Let x be the number. Write and solve an equation to find x. Show your work.
b. Does the solution of your equation solve the original problem? Explain.
Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
check
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63

What’s the answer for this one??
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.

1. Cesar invited 300 kids in the party. Only 15% of the kids did notshow up. How
many kids came to the party?
2. Rosa got 20% of an 80 item test incorrectly. How many items did she get
correctly?
3. There were 50 pupils in Grade Ill. If 28% of the pupils were absent, how many
pupils were present?
4. Out of 50 pupils, only 48 pupils joined the educational fieldtrip. What percent
joined the trip?
5. Among the 50 pupils in a Grade 6 class, 6% are left-handed. How many are left-
handed?
1.
300 x 0.15 = 45
300 - 45 = 255
255 kids came to the party
//
2.
80 x 0.20 = 16
80 - 16 = 64
She got 64 items correctly
//
3.
50 x 0.28 = 14
50 - 14 = 36
36 pupils were present
//
4.
48 / 50 = 0.96
0.96 x 100 = 96.0%
96% joined the trip
//
5.

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

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
