Answer:

for some reason i cant see ur attachment. lo siento

H and N are congruent because they are both 58 degrees,

J and L are congruent because they are both 62 degrees,

and K and M are congruent because they are both 60 degrees.

Therefore triangle HJK is congruent to triangle NLM.

Answer:

12 cookies for both friends (assuming you don't get any)

Step-by-step explanation:

24/2=12

since you seem like a kid, that slash means divided by

Answer: -21, what ever number you have you subtract 3 from that number. So after -9 would be -12 and so on

Answer:

-729

Step-by-step explanation:

Given is a geometric sequence.

Therefore,

a = - 1, r = - 3 /(-1) = 3, n = 7

[tex] a_7 =? [/tex]

[tex] \because a_n = ar^{n-1} [/tex]

[tex] \therefore a_7 = (-1)(3)^{7-1} [/tex]

[tex] \therefore a_7 = (-1)(3)^{6} [/tex]

[tex] \therefore a_7 = (-1)(729) [/tex]

[tex] \therefore a_7 = -729 [/tex]

Answer:

1/12

Step-by-step explanation:

1/6 divided by 2 = 1/12

Answer: R = √(3*r^2)

Step-by-step explanation:

For a cylinder with radius r and height H, the volume is:

V = pi*r^2*H

For a cone of height H, and with a base of radius R, the volume is:

V = (1/3)*pi*R^2*H

In this case, we know that both figures have the same height, and the same volume, then we can write:

pi*r^2*H = (1/3)*pi*R^2*H

Now we can divide by pi in both sides to get:

(pi*r^2*H)/pi = ((1/3)*pi*R^2*H)/pi

r^2*H = (1/3)*R^2*H

Now we can divide both sides by H:

(r^2*H)/H = ((1/3)*R^2*H)/H

r^2 = (1/3)*R^2

Now we want to write R in terms of r.

Then we need to isolate R in the above equation:

r^2 = (1/3)*R^2

3*r^2 = R^2

√(3*r^2) = R

R = √(3*r^2)

Answer:

50 degrees

Step-by-step explanation:

You can see that angle ADC is composed of angle ADB and angle BDC

Angle ADB is 38 degrees and angle BDC is 12 degrees

Therefore angle ADC is 50 degrees

Angle ADC is opposite from angle ABC so they are congruent.

So angle ABC is 50 degrees

Answer:

11. 35 ft²

12. 24 cm²

13. 18 ft²

14. 28 in²

15. 9 in²

Step-by-step explanation:

11. A= (b×h)÷2

= (10×7)÷2

= 70 ÷ 2

= 35 ft²

12. A= (b×h)÷2

= (8×6)÷2

= 48 ÷ 2

= 24 cm²

13. A=(b×h)÷2

=(9×4)÷2

= 36 ÷ 2

= 18 ft²

14. A=(b×h)÷2

=(7×8)÷2

= 56 ÷ 2

= 28 in²

15. A=(b×h)÷2

=(3×6)÷2

= 18 ÷ 2

= 9 in²

Good luck ^_^

977.85-2.5%= 953.40

977.85-953.40= £24.45 potentially saved.

Answer:£23.85 is your answer.

x+2.5%ofx=£977.85

x(1+2.5/100)=£977.85

x=£977.85/(1.025)=954

saving money will be =£977.85-954=£23.85

Answer:

the answer is 10.5m

Step-by-step explanation:

14.2m+3-2.1m+4.6

= 17.2m-2.1m+4.6

= 17.2m-6.7m

= 10.5m

the answer is 10.5m

Answer:

12.1m + 7.6

Step-by-step explanation:

14.2m + 3 - 2.1 + 4.6

Group like terms:

14.2 - 2.1 + 3 + 4.6

Add similar elements:

14.2m - 2.1m = 12.1m=

12.1m + 3+ 4.6

Add the numbers: 3 + 4.6 = 7.6=

12.1m + 7.6.

Please let me know if you have any questions

Answer:

5.  Since ∠CBD ≅ ∠CDB and ∠BAE ≅ ∠DEA, ΔABD and ΔBDE are equal. Therefore, the distances AD and EB are the same.

6.  Since ∠EBC ≅ ∠ECB and AE ≅ DE, ΔABE and ΔCDE are equal. Therefore, the distances AB and DC are the same.

I hope this helps!

Answer:

ΔCBD is isosceles as angles B and D are congruent

ΔCAE is also isosceles as angles A and E are congruent

CA ≅ CE as the triangle ΔCAE is isosceles

AD ≅ EB - corresponding parts of congruent triangles

ΔAEB ≅ ΔDEC - SAS congruency theorem

AB ≅ DC - corresponding parts of congruent triangles

Answer:

144

Step-by-step explanation:

12 times 12= 144

Answer:

576.09

Step-by-step explanation:

Answer:

14

Step-by-step explanation:

All of the angles are marked as congruent, which means it is an equlateral triangle. This means that all of the sides are congruent too.

Therefore z + 2 = 2z -10

add 10 to each side

z + 12 = 2z

subtract z from each side

12=z

now that we know that, we can plug it back in to either line (it doesn't matter because they're congruent)

line AB is z+2 which is 12+2 or 14

and line CB is 2z-10 which is 2(12)-10 or 24-10 which is also 14

so line CA is also 14 units long.
