[|] Answer [|]

$\boxed{5 \ \frac{5}{21}}$

[|] Explanation [|]

$-1 \ \frac{3}{7}$ * $-3 \frac{2}{3}$

-----------

Convert Fractions To Mixed Numbers:

$-1 \ \frac{3}{7}$ = $\frac{-10}{7}$

$-3 \ \frac{2}{3}$ = $\frac{-11}{3}$

Multiply Across:

$\frac{-10 \ * \ -11}{7 * 3}$

= $\frac{110}{21}$

Simplify:

= $5 \ \frac{5}{21}$

$\boxed{[|] \ Eclipsed \ [|]}$

What is the value for y? Enter your answer in the box. y=

Elodia [21]

Answer:

y = 14

Step-by-step explanation:

Since AC = BC then the triangle is isosceles and the base angles are congruent, that is

∠A = ∠B = 50°, thus

∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°

= 180 - 100 = 80°, hence

5y + 10 = 80 ( subtract 10 from both sides )

5y = 70 ( divide both sides by 5 )

y = 14

Answer:

$c=2d+5$

Step-by-step explanation:

Let

d ------> the number of days

c -----> the cost

we know that

The cost is equal to the number of days multiplied by $2 per day plus the initial fee of $5

The linear equation in slope-intercept form is

$c=md+b$

where

m is the slope

b is the c-intercept (value of c when the value of d is equal to zero)

in this problem we have

m=$2 per day

b=$5

substitute

$c=2d+5$

Hep me on this please

Alona [7]

Answer:

The answer is 2240m².

Step-by-step explanation:

Given that the formula of area of trapezium is A = 1/2×(a+b)×h where a and b represents the length and h is height :

$area = \frac{1}{2} \times (a + b) \times h$

$let \: a = 50 \\ let \: b = 90 \\ let \: h = 32$

$area = \frac{1}{2} \times (50 + 90) \times 32$

$area = \frac{1}{2} \times 140 \times 32$

$area = 70 \times 32$

$area = 2240 \: {m}^{2}$
