One interior angles for a pentagon

A television costs $400,00 cash. When bought on hire purchase, a deposit 1 point

aev [14]

Answer D. 170
$42.50 x 12 months = $510 + the $60.00 deposit is $570. You subtract $570-400 and you get $170.

three friends earned more than $200 washing cars. they paid their parents $28 for supplies and divided the rest of money equally

Flura [38]

28x+86≤200 because for supplies they divide the rest of money. that means, 200-28=172 so 172/2=86 now we gonna find the value of x.
28x+86≤200 i am gonna subtract 86 both of side 28x+86-86≤200-86 to get value of x.
28x≤114 divide 28 both of side to get value of x so it will be x≤4

Marysya12 [62]

36 and 144

Explanation

Two Angles are Supplementary when they add up to 180 degrees

Step 1

Let

x= angle 1

y= angle2

The measure of one angle is four times the measure of the other angle,then

$\begin{gathered} \text{angle}1=4\cdot\text{angle}2\text{ } \\ x=4y\text{ Equation(1)} \end{gathered}$

x and y are supplementary angles , then

$x+y=180\text{ Equation (2)}$

Step 2

use Equation (1) and (2) to find x and y

$\begin{gathered} x=4y \\ x+y=180 \end{gathered}$

replace Equation (1) in Equation (2)

$\begin{gathered} 4y+y=180 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}$

replace the value of y= 36 in equation (1) to find x

$\begin{gathered} x=4y \\ x=4\cdot36 \\ x=144 \end{gathered}$

Hence, the answer is 36 and 144

The line has the same slope as 3x-y=5 and the same y-intercept as the graph of 4y-7x=16

ArbitrLikvidat [17]

Well standard form is Ax+By=C, so just move the -7x to the front so -7x+47=16

Police estimate that 25% of drivers drive without their seat belts. If they stop 6 drivers at random, find the probability tha

Furkat [3]

Answer:

17.80% probability that all of them are wearing their seat belts.

Step-by-step explanation:

For each driver stopped, there are only two possible outcomes. Either they are wearing their seatbelts, or they are not. The drivers are chosen at random, which mean that the probability of a driver wearing their seatbelts is independent from other drivers. So we use the normal probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
