Answer:

Given all the blanks true explained below.

Step-by-step explanation:

Given the pairs of triangle,

First pair, ΔABC and ΔUVW

In these triangles to prove triangles congruent we need all three sides equal but AB≠UV. Hence, not congruent

Second pair, ΔABC and ΔGHJ

To prove triangles congruent we need all three sides equal but AB≠GH Hence, not congruent

Third pair, ΔABC and ΔPQR

To prove triangles congruent we need all three sides equal

AB=PQ=2 units

BC=\sqrt{(-1+4)^{2} + (1-4)^{2} } =\sqrt{18}units

QR=\sqrt{(-1-2)^{2} + (-1+4)^{2} } =\sqrt{18}units

AC=\sqrt{(-1+4)^{2} + (1-2)^{2} } =\sqrt{10}units

PR=\sqrt{(-1-2)^{2} + (-1+2)^{2} } =\sqrt{10}units

Hence, BC=QR, AC=PR

All 3 sides equal. By SSS rule both triangles congruent.

Fourth pair, ΔGHJ and ΔUVW

GH=UV=3 units

HJ=VW=2 units

Hence, by Pythagoras theorem,

GJ=UW=\sqrt{3^{2}+2^{2}}=\sqrt{13} units

Hence, All 3 sides equal. By SSS rule both triangles congruent.

Fifth pair, ΔGHJ and ΔPQR

To prove triangles congruent we need all three sides equal but PQ≠GH Hence, not congruent

Sixth pair, ΔPQR and ΔUVW

To prove triangles congruent we need all three sides equal but PQ≠UV. Hence, not congruent

10(2^×) + 7(3^×) = 6^× + 70​
Mkey [24]

Answer:

x = 2.81 and 2.096

Step-by-step explanation:

Given the expression

10(2^x) + 7(3^x) = 6^x + 70​

This can also be expressed as;

10(2^x) + 7(3^x) = (2*3)^x + 70

10(2^x) + 7(3^x) = 2^x*3^x + 70

Let a  = 2^x and b = 3^x

10a + 7b = ab + 70

10a + 7b - ab = 70

10a-ab + 7b - 70 = 0

a(10-b)+7(b-10) = 0

a(10-b)-7(10-b) = 0

a-7 = 0 and 10-b = 0

a = 7 and b = 10

Since a = 2^x

7 = 2^x

log 7 = log2^x

log7 = xlog2

x = log7/log2

x = 2.81

Similarly

10 = 3^x

log 10 = log 3^x

log 10 = xlog3

x = log 10/log 3

x = 1/0.4771

x = 2.096

Hence the values of x that satisfies the equation are 2.81 and 2.096

I NEED THIS ANSWERED ASAPPPPPP!!!!!!!!!!!!!1111 THANKS
Katyanochek1 [597]
The division is using extra zeros.
2 * 16  = 32, but 3200 was placed below 3426.

Now 1 * 16 = 16, so 160 goes below 226.
The number that goes in the box is 160.

A bus driver started her day with an empty bus. At her first stop she picked up
lidiya [134]

Answer:

12 people.

Step-by-step explanation:

Let's do this one at a time.

First stop:

0 + 11 = 11

Second stop:

11 + 5 = 16.

16 - 7 = 9.

Third stop:

9 + 5 = 14.

14 - 2 = 12.

<em>There</em><em> </em><em>were</em><em> </em><em>12</em><em> </em><em>people</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>bus</em><em> </em><em>after</em><em> </em><em>the</em><em> </em><em>driver</em><em> </em><em>left</em><em> </em><em>the</em><em> </em><em>third</em><em> </em><em>stop</em><em>.</em>
