A computer chip manufacturer made 230,00 chips last week .

For each hour he babysit,Anderson earns 1$ more than half of carey's hourly rate.Anderson earns 6$ per hour. wich equation can b

Lena [83]

Answer:

The expression to find Carey's hourly rate is: $c = 2*a - 2$ . Carey's hourly rate is $10.

Step-by-step explanation:

Anderson receives 1 more than half of carey's hourly rate. If we call Anderson's rate by "a" and Carey's by "c", we can express this phrase in the following equation:

$a = \frac{c}{2} + 1$

We want to find the Carey's rate, therefore we need to isolate the "c" variable.

$\frac{c}{2} + 1 = a\\\frac{c}{2} = a - 1\\c = 2*a - 2$

Since Anderson earns $6, then we can find Carey's rate:

$c = 2*6 - 2 = 12 - 2 = 10$

Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parr

Tcecarenko [31]

Answer:

The least possible number of coins the Pirate has = 81

Step-by-step explanation:

Given:

Pirate Jack has equal number of gold and silver coins.

When the pirate splits the coins into 7 equal piles he has 4 coins left.

When the pirate splits the coins into 11 equal piles he has 4 coins left.

Every pile has at least 1 coin.

To find the least possible number of coins Pirate Jack has.

Solution:

In order to find the least possible number of coins pirate Jack has, we must find the least common multiple of the number of piles the coins are split into.

So, the least common multiple of 7 and 11 can be found by listing the multiples.

$7= 7,14,21,28...............,77$

$11=11,22,33,44,55,66,77$

So, we find the least common multiple of 7 and 11 is 77.

Number of coins left = 4

Total number of coins the pirate must have = $77+4 =81$

We can check the answer by dividing 81 by 7 and 11. I both cases we get remainder = 4.

So, the least possible number of coins the pirate has = 81

Isabella earns interest at an annual rate of 10% compounded annually on her savings account. She deposits $2,000 into her accoun

IrinaK [193]

Answer:

10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.

Step-by-step explanation:

She starts off with 2000. She earns 10% of 2000 the first year. 10% of 2000 is 200. Then add to get the amount of money she has at the end of that year. 2000 + 200 = 2200. Then the next year she earns 10% of 2200. 10% of 2200 is 220. Add 2200 + 220. 2200 + 220 = 2420.

Answer:

ΔCFG is an isosceles triangle.

Step-by-step explanation:

From the picture attached,

From ΔABF and ΔEDG,

Conditions for ΔABF and ΔEDG by SSS property of congruence,

1). AB ≅ DE [Given]

2). (BC + CF) = (DF + CG)

CF = CG [Given → BC = DF]

3). FA ≅ EG

(AG + GF) ≅ (EF + GF)

AG ≅ EF

Since, two sides of ΔCFG are equal in measure

ΔCFG is an isosceles triangle.
