The ratio of the measures of the angles of a triangle is 5:6:7 find the measures of the angles of the triangle.
Answer:50°
Step-by-step explanation:
Let x represent the scale factor, the ratios are multiplied by:
5x°+6x°+7x°=180°
18x°=180°
x=10
Smallest Angle 5x°=5(10)°=50°

A new bagel store opened. The first day 15 customers entered the store. The number of
customers that enter the store triples each day after. Which function represents f(d), the
number of customers that enter on the d day?
1.
f(d) = 3(15)
2.
f(d) = 3d + 15
3
f(d) = 150 + 3
f(d) = 15(3)
Submit Answer
Answer:
[tex]f(d) = 15 + 3d[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] --- day 1
[tex]Rate = 3[/tex] -- i.e. triples daily
Required
Determine the function f(d)
The number of customers on a particular day is:
Customers = Day 1 + Rate * Number of days
Represent as a function:
[tex]f(d) = a + Rate* d[/tex]
Where d is the number of days.
So, we have:
[tex]f(d) = 15 + 3* d[/tex]
[tex]f(d) = 15 + 3d[/tex]

Benjamin bought a 3-pound bag of flour for $6.95. What is the unit price per ounce of flour? (1 pound = 16 ounces)
Answer:
Step-by-step explanation:
Since there are 16 oz in 1 lb, to find the amount in 3 lbs, you would just multiply it by 3
16 · 3 = 48
to find the price you divide the total price by number of oz.
6.95 ÷ 48 ≈ 0.1448
since money is measured in hundreths, you would round up (because thats how money works) so it would be roughly 15 cents. unless your teacher wants you to round down to 14 cents

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.
Answer:
Multiply both sides by -2 and reverse the inequality symbol.
Step-by-step explanation:
To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2
When multiplying or dividing by negatives, you must reverse the inequality symbol as well.
To isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
Isolating variables in inequalityIsolation of variables means making the variable the subject of the formula from the given expression.
Given the inequality expression -1/2 w < 12
To make w the subject of the formula, we will have to multiply both sides by -2 to have;
-1/2 w * -2 > 12 * -2
w > -24
Hence to isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.

Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

The coldest temperature in New York City was -15 on February 9th 1934, The next day the temperature rose 42 degrees. Write an expression for the temperature on February 10th
Answer:
27°C
Step-by-step explanation:
The temperature on February 9th 1934 = -15°C
The next day the temperature rose 42 degrees.
We need to find an expression for the temperature on February 10th.
February 10th temperature = -15 + 42
= 27°C
So, the temperature on February 10th is 27°C.
Answer: it would be 42+(-15)

Answer:
y +2 = -1/2(x -7)
Step-by-step explanation:
The line PQ has a rise of 6 units for a run of 3 units, so its slope is ...
m = rise/run = 6/3 = 2
A line perpendicular to PQ will have a slope that is the opposite reciprocal of that, so ...
-1/m = -1/2
We have the slope of the desired line, and a point it needs to pass through, so we can use the point-slope form of the equation of a line.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
An equation for the desired line is ...
y +2 = -1/2(x -7)
__
This can be rearranged to other forms.
y = -1/2x +3/2 . . . . . slope-intercept form
x +2y = 3 . . . . . . . . . standard form
