Answer:

C or D most likely C

Step-by-step explanation:

Definitely not A or B they don’t matter or make sense.. C makes more sense because it’s directly hit with heat needed to evaporate, for D to be lower it’ll take longer if at all to evaporate because it’s colder closer to the sea floor

Answer:

9.) $t=.05m+20$

10.) $t=.10m+5$

11.) $300$ minutes of calling would make the two plans equal.

12.) Company B.

Step-by-step explanation:

Let t equal the total cost, and m, minutes.

Set up your models for questions 9 & 10 like this:

total cost = (cost per minute)# of minutes + monthly fee

Substitute your values for #9:

$t=.05m+20$

Substitute your values for #10:

$t=.10m+5$

To find how many minutes of calling would result in an equal total cost, we have to set the two models we just got equal to each other.

$.10m+5=.05m+20$

Let's subtract $5$ from both sides of the equation:

$.10m=.05m-15$

Subtract $.05m$ from both sides of the equation:

$.05m=15$

Divide by the coefficient of $m$ , in this case: $.05$

$m=300$

Let's substitute $200$ minutes into both of our original models from questions 9 & 10 to see which one the person should choose (the cheaper one).

Company A:

$t=.05(200)+20$

Multiply.

$t=10+20$

Add.

$t=30$

Company B:

$t=.10(200)+5$

Multiply.

$t=20+5$

Add.

$t=25$

If 1/8(8x+15)24, what is the value of x?

Lelechka [254]

Answer:

$x=22.125$ or $x=\frac{177}{8}$

Step-by-step explanation:

The correct equation is

$1/8(8x+15)=24$

solve for x

Multiply by 8 both sides to remove the fraction

$(8x+15)=192$

subtract 15 both sides

$8x=192-15\\8x=177$

divide by 8 both sides

$x=\frac{177}{8}$

$x=22.125$

Please help it’s due tonight. Your help will be greatly appreciated.There is also a graph. WILL PUT YOU AS BRAINLY!!!!!!

chubhunter [2.5K]

Answer: see below

Step-by-step explanation:

The shape is a trapezoid

Base 1 (BH) is 10

Base 2 (QA) is 14

Height is 5

Area

$A=\frac{base_{1} +base_{2} }{2} h$

$A=\frac{10+14}{2} *5\\A=12*5\\A=60$

Find distance between QB and HA

$D=\sqrt{(x_{2} -x_{1}) ^{2}+(y_{2}-y_{1}) ^{2}$

Q( -4,4) B (-2,9)

$D=\sqrt{(-2--4)^{2}+(9-4)^{2} } \\D=\sqrt{2^{2} +5^{2} } \\D=\sqrt{29}$

Perimeter

$P=10+14+2\sqrt{29} \\P=24 +2\sqrt{29} \\P= 24+10.77\\P=34.77$

Consider the linear equation y=4x-7 find the value of y that makes the given ordered pair a solution to the equation (3, y) Y=

olchik [2.2K]

Y = 4x - 7 is a line with a slope of 4 and y-intercept of -7.

plug in any X value, for example 1 and you get the following

y = 4(1) - 7

y = -3

(1,-3) is a point that satisfies the equation y = 4x - 7
