Answer:

x = 32

Step-by-step explanation:

This is an equilateral triangle. This means the angles of the triangle are all equal. Since the sum of a triangle's angles is 180°, that means each angle will be 60°.

$2x-4=60\\2x=64\\x=32$

Answer:

Step-by-step explanation:

in parallelograms, the measure of reciprocal angles is equal to 180 because they are supplementary,

m<D = 110 so the measure of m<A which is reciprocal to m<D is equal to 70

Ari thinks the perfect milkshake has 3 ounces of caramel for every 5 scoops of ice cream. Freeze Zone makes batches of milkshake

aleksandr82 [10.1K]

Step-by-step explanation:

Let $t$ be the number of ounces of caramel that has to be added to each scoop of ice cream.

So,for $n$ scoops,there has to be $n\times t$ ounces of caramel.

It is given that for every 5 scoops of ice cream,3 ounces of caramel has to be added.

So, $5\times t=3$

and $t=0.6$

For 8 scoops of ice cream,there has to be $8\times t=8\times 0.6=4.8$ ounces of caramel added.

But Freeze Zone adds 6 ounces of caramel.

So,Ari thinks that Freeze Zone adds more caramel

This summer, due to some renovations, a sports club has 105 members. The club's records indicate that this is 25% fewer members

Levart [38]

Answer:

140

Step-by-step explanation:

we know that this year the sports club has 25% less memeber, so if last year the members where 100% this year there are only 75%

and that 75% is equal to 105 members

we can represent the information that we are given in a table:

memebers percentage

105 ⇒ 75%

since last summer there were the 100% of member we can represent the number of members from last summer with 'x', and the table now is:

memebers percentage

105 ⇒ 75%

x ⇒ 100%

and we use rule of three to solve this problem: multiply cross quantities (105 by 100) and divide by the remaining amount:

x = 105*100/75

x = 140

Last summer the sports club had 140 members

37. Socks. In your sock drawer you have 4 blue socks, 5 grey socks, and 3 black ones. Half asleep one morning, you grab 2 socks

mihalych1998 [28]

Answer:

a) $\frac{1}{22}$

b) $\frac{7}{22}$

c) $\frac{5}{11}$

d) $\frac{35}{66}$

Step-by-step explanation:

Given,

Number of blue socks = 4,

Grey socks = 5,

Black socks = 3,

Total socks = 4 + 5 + 3 = 12,

Ways of choosing any 2 socks = $^{12}C_2$

$=\frac{12!}{2!10!}$

$=\frac{12\times 11}{2}$

$=6\times 11$

= 66,

a) Ways of choosing 2 blue socks = $^3C_2$

= 3,

Since, $\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

Thus, the probability of selecting 2 blue socks = $\frac{3}{66}=\frac{1}{22}$

b) Ways of choosing 2 shocks, non of them are grey socks = $^7C_2$

$=\frac{7!}{2!5!}$

$=7\times 3$

$=21$

Thus, the probability of selecting no grey socks = $\frac{21}{66}$

$=\frac{7}{22}$

c) ways of selecting atleast 1 black sock = ways of selecting 1 black sock + ways of selecting 2 black socks

$=^3C_1\times ^9C_1+^3C_2$

$=3\times 9 + 3$

$=27 + 3$

= 30,

Thus, the probability of selecting at least 1 black sock = $\frac{30}{66}$

$=\frac{5}{11}$

d) Ways of selecting a green sock = $^5C_1\times ^7C_1$

= 35,

Thus, the probability of selecting a green sock = $\frac{35}{66}$
