The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′. Which statement correctly describes the relationship between △DEF and △D′E′F′ ?

Answer: B. The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.

Step-by-step explanation:

Given : The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′.

We can see that a scale factor (2) is used in the above rule.

Rigid motions do not use any scale factor.

The transformation that uses scale factor to transforms figure is dilation.

And Dilation is not rigid motion because it does not produce congruent images.

Hence, The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.

val has 2 hours to finish a slide presentation. it takes her 1 over 6 hour to create each slide. will val have enough time to cr

vitfil [10]

Answer:

Yes she can.

Step-by-step explanation:

Val can make 6 slides in an hour.

1/6 * 60 minutes = 10 minutes. per slide

10 20 30 40 50 60 gives you six sldes, 1 every ten minutes.

=====================

In one hour, she can produce 6 slides.

In two hours, she can produce 12 slides (2 * 6 = 12)

Since she only needs 1 hour and 40 minutes to produce 10 slides, she is under her time limit of 2 hours.

Brett has 2/3 of a pound of almonds to divide equally among 4 bags. Find the amount of almonds that will be in each bag. Explain

baherus [9]

Answer:

1/6 of a pound.

Step-by-step explanation:

Write the expression, $\frac{2}{3}$ ÷ 4.

To divide with fractions, invert the second number and multiply.

$\frac{2}{3}$ ÷ 4 becomes $\frac{2}{3}*\frac{1}{4}$ .

To multiply fractions, multiply the numerators then multiply the denominators.

$\frac{2}{3} * \frac{1}{4} = \frac{2*1}{3*4} =\frac{2}{12}=\frac{1}{6}$

Pls help me with trig i would rlly appreciate !! 22 only

IRISSAK [1]

Step-by-step explanation:

given,

tan thita =8/9

or,tan thita=p/b

now, h=

$\sqrt{p {}^{2} + b {}^{2} }$

$= \sqrt{8 {}^{2} + 9 {}^{2} }$

$= \sqrt{145}$

therefore, h=

$\sqrt{145}$

now, cos thita =b/h

so, cos thita =

$9 \div \sqrt{145}$

$= 9 \sqrt{145} \div \sqrt{145}$

Answer:

Answers are below

Step-by-step explanation:

1. List all possible outcomes

HHH HHT HTH HTT TTT THH THT TTH

2. The probability of tossing 2 tails and 1 head is 3/8.

3. The probability of getting exactly 1 tail is 3/8. The probability of tossing at least 2 heads is 4/8 or 1/2. There is a greater chance of tossing at least 2 heads than tossing exactly 1 tail.

2/5 + 3/8 - Adding fractions

m_a_m_a [10]

Answer:31/40

Step-by-step explanation:

To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
