Step-by-step explanation:

Since XY = XZ = 6, then the triangle is isosceles.

The base angles are therefore congruent, that is

∠ Y = ∠ Z = 70°

The sum of the 3 angles in the triangle = 180°, thus

∠ X = 180° - (70 + 70)° = 180° - 140° = 40° → C

Answers

Answer:

$11.97

Step-by-step explanation:

If Carter were to tip that 18%, then he should give a $11.97 tip.

Step-by-step explanation:

  Step one:

Given that membership is $9 and the cost per visit is $1

let the number of visits be x

and the total cost be y

the total cost  for the situation is modeled as

y=mx+c-----equation of a line

   Step two:

given that x=23, we can solve for the totals cost as

by substituting we have

y=1*23+9

y=23+9

y=32

If l, m, and n are parallel, solve for x. Type in numerical values only, do not type in x=

Answers

Answer:

x = 11

Step-by-step explanation:

According to proportionality theorem, the transversal is divided proportionally as it cuts across parallel lines l, m, and n.

Therefore:

[tex] \frac{12.8}{x + 5} = \frac{x - 3}{10} [/tex]

Cross multiply

[tex] (12.8)(10) = (x + 5)(x - 3) [/tex]

[tex] 128 = x^2 - 3x + 5x - 15 [/tex]

[tex] 128 = x^2 + 2x - 15 [/tex]

[tex] 0 = x^2 + 2x - 15 - 128 [/tex]

[tex] 0 = x^2 + 2x - 143 [/tex]

Factorise:

[tex] 0 = x^2 - 11x + 13x - 143 [/tex]

[tex] 0 = x(x - 11) +13(x - 11) [/tex]

[tex] 0 = (x - 11)(x + 13) [/tex]

x = 11 or x = -13

We'd take the positive value.

Therefore, the value of x is 11.

Answer:

x : y : z = 9 : 10 : 6

Step-by-step explanation:

Expressing the ratio y : z = 5 : 3 in fractional form, that is

[tex]\frac{y}{z}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

5z = 3y ( divide both sides by 5 )

z = [tex]\frac{3}{5}[/tex] y = [tex]\frac{3}{5}[/tex] × 10 = 3 × 2 = 6

Thus

Using compound interest, it is found that it would take 11 years for the value of the account to reach $70,900.

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.

Hence, the parameters are given as follows:

[tex]A(t) = 70900, P = 37000, n = 365, r = 0.057[/tex]

We have to solve for t, then:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]70900 = 37000\left(1 + \frac{0.057}{365}\right)^{365t}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = \frac{70900}{37000}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = 1.91621622[/tex]

[tex](1.00015616)^{365t} = 1.91621622[/tex]

[tex]\log{(1.00015616)^{365t}} = \log{1.91621622}[/tex]

[tex]365t\log{1.00015616} = \log{1.91621622}[/tex]

[tex]t = \frac{\log{1.91621622}}{365\log{1.00015616}}[/tex]

t = 11.41

Rounding to the nearest year, it would take 11 years for the value of the account to reach $70,900.
