Patty is 50 mi. due north of Todd. Emma is due east of Todd. Ifa line were drawn from Emma

zubka84 [21]

Answer:

Correct choice is D

Step-by-step explanation:

Consider right triangle PTE (Patty, Todd, Emma). In thistriangle PT=50 mi - the distanse between Patty and Todd, the distance between Patty and Emma PE and the distance between Emma and Todd ET are unknown. The angle PET has the measure of 40°. Then

$\sin 40^{\circ}=\dfrac{PT}{PE}\Rightarrow PE=\dfrac{PT}{\sin 40^{\circ}}=\dfrac{50}{\sin 40^{\circ}}\approx 78\ mi.$
$\tan 40^{\circ}=\dfrac{PT}{ET}\Rightarrow ET=\dfrac{PT}{\tan 40^{\circ}}=\dfrac{50}{\tan 40^{\circ}}\approx 60\ mi.$

Answer:

Part a) $22.95+0.43x \leq 25$

Part b) The maximum number of candy bars that you can purchase is 4

Part c) The change would be $\$0.33$

Step-by-step explanation:

Part a) Write an equation representing your shopping experience and use x for the number of candy bars

Let

x -----> the number of candy bars

we know that

The inequality that represent this problem is equal to

$2(3.50)+2(2.75)+10.45+0.43x \leq 25$

$22.95+0.43x \leq 25$

Part b) Solve the equation to determine how many candy bars can you purchase?

$22.95+0.43x \leq 25$

Solve for x

Subtract 22.95 both sides

$0.43x \leq 25-22.95$

$0.43x \leq 2.05$

Divide by 0.43 both sides

$x \leq 2.05/0.43$

$x \leq 4.8$

The maximum number of candy bars that you can purchase is 4

Part c) How much change would you have left?

If you purchase 4 candy bars

then

$22.95+0.43(4)=\$24.67$

therefore

$\$25-\$24.67=\$0.33$

Mr. Hudkins wants his 6th grade math class to memorize their multiplication facts. He decides to increase the number of facts th

Maksim231197 [3]

Answer: m = 15w

Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.
