A small submarine starts at - 1.260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes What expression represents the new position of the submarine in relation to sea level?

Answers

Answer 1

Answer:

The submarine is at -1260 ft.

It descends 5 ft/min for 12 min.

12 min * 5 ft/min = 60 ft.

It descended 60 ft, so you must subtract 60 ft from -1260 ft.

-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft

The error in the last line in the problem is that (-5)(12) = -60, not 60.

The correct line is:

-1260 + (-5)(12) = -1260 - 60 = -1320

2. Reflexive Property of Congruence

3. Angle DGF congruent to Angle DEF

Step-by-step explanation:

Opposite sides of a parallelogram are parallel , so angle 1 ≅ angle 3 and angle 2 ≅ angle 4 because they are alternate interior angles . By the reflexive property of congruence DF ≅ DF . Therefore , △ DGF DEF by the ASA congruence postulate . That means DE ≅GF and DG ≅EF by CPCTC .

Martin is an after school math tutor . He noticed that 6 people still needed help on 2/5 of the tutoring session time was left.Scince each person was given an equal amount of time, martin wrote the expression below to find the fraction or the toutoring session each person who still needed help would be allotted. 2/5 divided by 6 which expression is equivalent to martins expression?

Answers

Answer:

6/15 ÷ 6

Step-by-step explanation:

Martin is an after school math tutor

He noticed that 6 people still needed help on 2/5 of the time that was left

Martin wrote the expression

2/5 ÷ 6

This expression can be used to determine the number of persons who still need help

Therefore the expression that is equivalent to Martin's expression is

= 6/15 ÷ 6

Using 3 to divide both 6 and 5 will give

2/5 ÷ 6

Hence the expression which is equivalent to Martin's expression is 6/15 ÷ 6

Answers

Answer:

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

Step-by-step explanation:

Using, the formula y1+y2/x1-x2,

Choosing any two points, make the expression:

1-2/125-155

simplify:

-1/-30

the slope of the equation is -1/-30.

to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:

y would be 2

x would be 155

b is the y intercept

2= -1/-30•155 + b

2=5⅙+b

b = - 3⅙

the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.

To make a base for a jar of handmade cream, Barbara needs 3 tablespoons of coconut butter for every cup of beeswax. Which statement below is TRUE about this scenario?
a) The ratio of a jar of handmade cream to coconut butter is 3:1.
b) The ratio of beeswax to coconut butter is 3 to 1.
c) The ratio of beeswax to coconut butter is 1 to 3.
d) The ratio of coconut butter to beeswax is 1 to 3.

Answers

Answer:

c) The ratio of beeswax to coconut butter is 1 to 3.

Step-by-step explanation:

A ratio can be defined as a mathematical expression used for the comparison of two (2) values or quantities.

Basically, a ratio gives the relationship between two values or quantities by comparing them together. It is typically written in the form; x : y

In this scenario, to make a base for a jar of handmade cream, Barbara needs 3 tablespoons of coconut butter for every cup of beeswax. The statement which is true about this scenario is that, the ratio of beeswax to coconut butter is 1 to 3.

Given the following data;

Amount of coconut butter (X) = 3 tsp

Amount of beeswax (Y) = 1 cup

The ratio of beeswax to coconut butter is;

Y : X = 1 : 3

Hence, the ratio of beeswax to coconut butter is 1 to 3.

a common mistake people make when working with exponents is to multiply the base by the exponent instead of raising the base to the power of the exponent. For instance, they would mistakenly say that 2^3 is 6 (because 2x3=6) when the correct answer is actually 8 (2x2x2=8) are there any pairs of numbers for which this mistake in thinking actually gives the correct answer? In other words are there any solutions to the equation a^x=a X what are the?

Answers

Answer:

The pair of number are (2 and 1), (2 and 2)

Step-by-step explanation:

The pair of number that makes the expression [tex]a^x = ax[/tex] true are 2 and 2 as shown:

where a = 2 and x =2

2² = 2*2

2² = 4

and:

2*2 = 4

Hence 2²  = 2(2) = 4 making the expression [tex]a^x = ax[/tex] true for both pair of numbers

Also the number pair 1 and 2 makes the expression correct as shown:

[tex]2^1 = 2(1)\\2 = 2 (true)[/tex]

Henry makes $12.50 per hour for the first 40 hours he works in a week. For 5 points
each additional hour he makes $18 per hour. How much did he make if he
worked 44 1/2 hours last week? *

Answers

Answer:

He made $581 if he worked 44 1/2 hours last week

Step-by-step explanation:

Let us solve the question

∵ Henry makes $12.50 per hour for the first 40 hours

∵ For each additional hour, he makes $18 per hour

→ We need to find how much he made if he worked 44 1/2 hours

→ At first, find his earning for the first 40 hours

∵ His earning in the first 40 hours = 40 × 12.50

∴  His earning in the first 40 hours = $500

→ Find how many hours he worked after the first 40 hours

∵ 44 1/2 - 40 = 4 1/2 hours

∴ He worked 4 1/2 hours over the first 40 hours

→ Find his earning from them

∵ His earning in 4 1/2 hours = 4 1/2 × 18

His earning in 4 1/2 hours = $81

→ Now add the two amounts to find his total earning

∵ His total earning = 500 + 81

∴ His total earning = $581

He made $581 if he worked 44 1/2 hours last week

the batting wang xiu ying uses to fill quilts has a thermal conductivity rate of 0.03 watts (W) per meter(m) per degree celsius. what is the batting thermal conductivity when w/cm•c

Given

K = 0.03W/m°C

Required

Convert K to W/cm°C

Since 1m = 100cm,

K = 0.03w/1×100cm°C

K = 3×10^-2w/10² cm°C

K = 3 × 10^-2w/10² cm°C

K = 3w× 10^{-2-2}cm°C

K = 3w×10^-4cm°C

K = 0.0003w/cm°C

Answer:

0.0003

Step-by-step explanation:

DID IT ON KHAN

and Since 1m = 100cm,

K = 0.03w/1×100cm°C

K = 3×10^-2w/10² cm°C

K = 3 × 10^-2w/10² cm°C

K = 3w× 10^{-2-2}cm°C

K = 3w×10^-4cm°C

K = 0.0003w/cm°C
