LAST ONE \small \angle L and \small \angle M are supplementary, \small m\angle L=12x+45 and \small m\angle M=18x-30. Determine t

FinnZ [79.3K]

Answer:

$m\angle L = 111\degree \\m\angle M = 69\degree$

Step-by-step explanation:

Since, angle L and angle M are supplementary.

$\therefore m\angle L + m\angle M= 180\degree \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree \\ x = \frac{165 \degree}{30} \\ x = 5.5 \degree \\ \\ m\angle L = 12x + 45 \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L = 66 + 45 \\ \huge \red{ \boxed{ m\angle L = 111 \degree}} \\ \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\$

Please need help on this please

STatiana [176]

Answer:

C

Step-by-step explanation:

Given

x² - 10x + 24 = 0

Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 4 and - 6, since

- 4 × - 6 = + 24 and - 4 - 10 = - 10, hence

(x - 4)(x - 6) = 0 ← in factored form → C

Casey has a small business making dessert baskets. She estimates that her fixed weekly costs for rent and electricity are $200.

lisov135 [29]

Answer:

a) Total weekly cost = $300

b) For Cassey to break even she has to sell 4 baskets

Step-by-step explanation:

Cost of electricity and rent in a week = $200

Cost of ingredients to make one dessert basket = $2.50

Total cost of making 40 dessert basket= 40*25

= $100

a) Cassey total cost in a week is $200 + $100

= $300

b) if each basket is sold at $25,the total selling price of 40 baskets will be $(25*40)

= $1000.

For Cassey to break even with the cost of production she has to sell y basket.

y = cost of producing 25 baskets / cost of selling 1 basket

y = 100/25

y = 4 baskets

When Nayeli goes bowling, her scores are normally

Ber [7]

Using the normal distribution, it is found that she scores less than 128 in 28.1% of her games.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean $\mu$ and standard deviation $\sigma$ is given by:

$Z = \frac{X - \mu}{\sigma}$

The z-score measures how many standard deviations the measure is above or below the mean.

Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are given, respectively, by $\mu = 135, \sigma = 12$ .

The proportion of games in which she scores less than 128 is the <u>p-value of Z when X = 128</u>, hence:

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{128 - 135}{12}$

Z = -0.58

Z = -0.58 has a p-value of 0.281.

She scores less than 128 in 28.1% of her games.
