Answer: 1.1 seconds

<u>Step-by-step explanation:</u>

leap = 4t²  ; leap = 4 ft 11 inches, find t

4\frac{11}{12} = 4t^2

\frac{59}{12} = 4t^2

\frac{59}{48} = t^2

\sqrt{\frac{59}{12}} = \sqrt{t^2}

\sqrt{1.23} = t

1.1 = t

Are triangles DEF and LNM similar if DF = 8 and LM = 4?
Komok [63]

We Cannot conclude that triangles DEF and LNM are similar if DF = 8 and LM = 4.

<u>Solution:</u>

Given that for two triangle DEF and LNM, DE = 8 and LM = 4.

To say that two triangles are similar the provided information is not complete.  

Two triangles DEF and LNM , will be similar if there corresponding sides are in ratio which means

\frac{\mathrm{DE}}{\mathrm{LM}}=\frac{\mathrm{EF}}{\mathrm{NM}}=\frac{\mathrm{EF}}{\mathrm{NM}}

But we have only information of  \frac{\mathrm{DE}}{\mathrm{LM}}=\frac{8}{4}=2

But do not have any information regarding two remaining ratios that are  \frac{\mathrm{EF}}{\mathrm{NM}} \text { and } \frac{\mathrm{EF}}{\mathrm{NM}}

Hence cannot conclude that triangles DEF and LNM similar if DF = 8 and LM = 4

Pls, I request ya all, exams are near, I am not able to figure out the answer (along with process) of this question. Pls, I will
DENIUS [597]

What this question is asking us is

A) From -40C to 5 0c How much did it rise

The formula for this would be

Risen Temperature - Initial Temperature

The risen temparauture is 5 so we plug the 5 in first then the 4 so it would look like

5-(-4)=9

And remeber when you have 2 negatives it becomes a positie, 5+4=9

The asnwer for A is 9 degress

B) The tempurater then fell by 7 degress from 5 so we just have to do

5 - 7

which is -2 Celcius

Which ordered pair is a solution of the equation?<br> y=4x−7
vampirchik [111]

Answer:

Unknown

Step-by-step explanation:

Hi! so you didn't add the ordered pair options but I will do my best :) so if you see the ordered pair (0.7) that could definitely be a solution because using the slope intercept form equation you gave I know that's our y Intercept. the slope is 4/1 so moving up 4 and to the right 1 or down 4 and to the left 1 on a graph could show you more points! If you don't want to draw it you could use Desmos and just put this equation in or give me the ordered pairs and I will give you your answer!

hope this helps :)
