Pls help with the question in the picture
Answer:
Step-by-step explanation:
m∠ABC = [tex]\frac{1}{2}[/tex] m∠AOC = 54°
Answer: 54°
because ∠ADC is the angle at the center of the arc AC and ∠ABC is the inscribed angle of the arc AC
=> m∠ABC = 1/2. m∠ADC = 108/2 = 54°

What is x=7 in slope intercept form
Please help
Answer: x=7 or undefined
Step-by-step explanation:
We can't write x=7 in slope intercept form, since it doesn't have an actual slope or y-intercept. You could put undefined, since the slope is undefined.
Of the 520 students participating in a chess tournament, 35% were male. How many females were in the tournament?
Answer:
182
Step-by-step explanation:
take 520 and multiply by 0.35
The number of female students participated in a chess tournament is 338.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 520 students participating in a chess tournament, 35% were male.
Number of male students = 35% of 520
35/100 ×520
= 0.35×520
= 182
So, the number of female students
= 520-182
= 338
Therefore, the number of female students participated in a chess tournament is 338.

Vijay’s wages were increased from £115 per week to £130 per week.
What was the percentage increase to one decimal place?
Answer:
13%
Step-by-step explanation:
Increase = (New Number - Old Number) / Old Number
(130 - 115) / 115
15/115 = 0.130434783.
0.130434783 * 100 (to get the percentage) = 13.0%

wyatt opend a savings account 4 years ago. the account earns 4%interest compounded quarterly if the current balance is $1,000.00 how much did he deposit initially round your answer to the nearest cent
Answer:
He deposited initially $852.82
Step-by-step explanation:
The rule of the compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex], where
A is the new amountP is the initial amountr is the rate in decimaln is the period of the timet is the time∵ Wyatt opened a savings account 4 years ago
∴ t = 4
∵ The account earns 4% interest compounded quarterly
∴ r = 4% = 4 ÷ 100 = 0.04
∴ n = 4 ⇒ compounded quarterly
∵ The current balance is $1,000.00
∴ A = 1,000
→ Substitute these values in the rule above to find P
∵ 1,000 = [tex]P(1+\frac{0.04}{4})^{4(4)}[/tex]
∴ 1,000 = [tex]P(1+0.01)^{16}[/tex]
∴ 1,000 = [tex]P(1.01)^{16}[/tex]
→ Divide both sides by [tex](1.01)^{16}[/tex]
∴ 852.8212622 = P
→ Round it to the nearest cent (2d.p)
∴ P = 852.82
∴ He deposited initially $852.82

15) A car salesman earns $700 per week plus 2.5% commission on his sales. If he
sold two cars for a total of $75,000 last week, how much did he make?
Please help!
Answer:
$2575
Step-by-step explanation:
For this problem, we need to form an equation that represents the car salesman's weekly income. We are given that he makes at least $700 per week and that he makes 2.5% commission for his sales. Let n represent the total amount of sales the car salesman made. So we can build the equation as follows:
f(n) = 0.025n + 700
Note that if we let n = 0 (He made no sales) then he will make his minimum weekly income of $700.
So let's use our formula to calculate how much he made for the week given he made $75000 in sales.
f(75000) = 0.025(75000) + 700
f(75000) = 1875 + 700
f(75000) = 2575
Hence, the car salesman made $2575 for the week.
Cheers.
3) WeSell4Less car dealership has 175 cars in their sales lot. On average they sell 20% of their cars in a month. In the next month how many cars would should they sell? please help me solve this
Answer:
They should sell 35 cars next month.
Step-by-step explanation:
From the information given, you know that the dealership sells 20% of their cars in a month and you should calculate 20% of the amount of cars they have in their sales lot to know the amount of cars that they should sell next month:
175*20%=35
According to this, the answer is that they should sell 35 cars next month.

What is a scale factor?
The ratio of weight of similar 2-D figures
The ratio of corresponding angles of similar figures
The ratio of corresponding sides of similar figures
The ratio of volume of similar 2-D figures
Answer:
Here is some helpful information from my mini lessons.
Step-by-step explanation:
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides. Here you'll learn that the ratio of the perimeters of similar figures is equal to their scale factor and that the ratio of their areas is equal to the square of their scale factor. If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.
PLSSSSSS HELP ME I WILL GIVE BRAINLY
Answer: (2,2)
Step-by-step explanation:
The solution of the system of equations is the intersection point, or the point where both lines meet. Looking at the graph, we see that the blue and red line meet at (2,2). That means the solution is (2,2).
We can also solve this algebraically. Since we are given that y=x, we can plug that into the equation and solve.
y+2y=6 [combine like terms]
3y=6 [divide both sides by 3]
y=2
Since we are told that y=x, we know that x is also 2. This tells us that the solution is also (2,2).
