natka813 [3]

Answer:

-22.2

Step-by-step explanation:

Then, because the problem states "is at least" we know this is an inequality problem and specifically the inequality operator is:

≥

Now, we can write and solve the inequality as:

5(x+26)≥19(5x(5×26)≥195x+130≥195x+130−130≥19−1305x+0≥−1115x≥-1115x5≥−11155x5≥−22.2x≥−22.2

The number is at least

−22.2 or the number is greater than or equal to −22.2

Sophia exchanged 1,000 US dollars for the south African currency. the exchange rate was 7.15 rand to $1.00.
mel-nik [20]
1 / 7.15 = 1000 / x......$ 1 to 7.15 rand = $ 1000 to x rand
cross multiply because this is a proportion
(1)(x) = (7.15)(1000)
x = 7150 <=== Sophia got 7150 rand

Find the measure of the indicated angle to the nearest degree.<br> 8<br> 22<br> ?
Blizzard [7]

Answer:

21 degrees

Step-by-step explanation:

To find this, we are going to use the appropriate trigonometric ratio

The right angle faces the length 22 which is the hypotenuse

The marked angle faces the length 8 which makes it the opposite

The trigonometric ratio that links the two is the sine

The sine is the ratio of the opposite to the hypotenuse

So, we have it that;

sine ? = 8/22

? = arc sine 8/22

? = 21 degrees

Max was on vacation twice as long as Jared and half as long as Wesley. The boys were on vacation a total of 3 weeks. How many da
GuDViN [60]
Lets say W=Wesley, M=Max, and J=Jared.
So your equations are M=2J, 2M=W, and M+J+W=21days(3 weeks)
So substituting M and W into M+J+W=21 gives you 2J+J+2M=21, substitute M again, to get 2J+J+4J=21 so you get 7J=21 so J= 3 days. Using J=3, substitute in to find M, using M=2J, so M=2(3) so M=6 and using that, substitute into 2M=W, so 2(6)=W so W=12. And 12+6+3=21 to check.
