I'm rather stuck on this question

White raven [17]

Answer:

m<a = 30°

m<b = 90°

m<c = 60°

Step-by-step explanation:

Angles a, b, and c are all angles on a straight line.

Angles on a straight line add up to 180°.

Therefore, a + b + c = 180°

Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:

Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°

m<a = $\frac{1}{6} * 180 = 30$

m<b = $\frac{3}{6} * 180 = 90$

m<c = $\frac{2}{6} * 180 = 60$

Hey Cara van cross 1378 Miles of Desert in 85 days Is troubling 22 miles on the first day and 28 miles on the second day if the

nikklg [1K]

Answer: it will travel 16 miles on each of the remaining days.

Step-by-step explanation:

Total number of miles that the caravan will cross in the desert is 1378. It covered 22 miles on the first day and 28 miles on the second day. Total number of miles which the caravan covered on the first day and second day is 28 + 22 = 50 miles. Total number of miles left to be covered is 1378 - 50 = 1328.

Total number of days left is 85 - 2 = 83.

if the caravan travel the same number of miles on each of the remaining days, the number of miles travelled on each day would be

1328/83 = 16 miles

What is the explicit formula for the arithmetic sequence -100,-70,-40,-10

kherson [118]

The explicit formula of an arithmetic sequence:

$a_n=a_1+(n-1)d$

We have:

$a_1=-100,\ a_2=-70,\ a_3=-40;\ a_4=-10,\ ...\\\\d=a_{n+1}-a_n\to d=-70-(-100)=-70+100=30$

Substitute:

$a_n=-100+(n-1)(30)=-100+30n-30=30n-130$

Answer: an = 30n - 130

Please help!! Will mark BRAINLIEST!! <br><br> Find an equation for the graph sketched below:

Sedbober [7]

The equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$

The given graph is an exponential graph and the standard exponential graph is expressed as $y=ab^x$

a is the y-intercept of the graph

(x, y) is any point on the graph.

Given the following from the graph;

a = -3

(x, y) = (1, 1)

Substitute the point and the y-intercept into the formula to have

$1=-3\cdot b^1\\\b = -\frac{1}{3} \$

Get the required exponential equation:

Recall that $y=ab^x$

$y=-3 \cdot (-\frac{1}{3} )^x$

Hence the equation for the graph sketched below is $y=-3 \cdot (-\frac{1}{3} )^x$
