Answer:

Both angles are equal because they are corresponding so:

2x + 5 = 3x - 7

2x + 12 = 3x

x = 12

According to the graph, the number of barrels that the two machines would have filled at about the same time is; Option B; 50 Barrels

We are told that;

- Two machines fill water barrels

- One machine had filled 30 barrels before the faster machine started

- At a certain tile, they would have filled a number of water barrels at about the same time.

Now, from the graph, we see that;

The red line indicates the slower machine while the blue line indicates the faster machine.

From the graph, the number of barrels at intersection point is 50 barrels.

Answer:

1. Angle 1 congruent to Angle 3, Angle 2 congruent to Angle 4 ( top row last box in answer choices)

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 .

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

Answer:

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]

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

Answer:

A 6/15 divided by 6 on edge

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.

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.

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
