Answer:
x = 40
Step-by-step explanation:
∠D = ∠ADB + ∠BDC
= 30 + 40
= 70°
In ΔBDC,
BD = CD
∠DBC = ∠DCB {angles opposite to equal sides are equal}
∠DBC + ∠DCB + ∠BDC = 180 {Angle sum property}
2∠DCB + 40 = 180
2∠DCB = 180 -40
2∠DCB = 140
∠DCB= 140/2
∠DCB = 70°
In ΔADC,
x + ∠D + ∠C = 180
x + 70 + 70 = 180
x + 140 = 180
x = 180 - 140
x = 40°

Susan said, "I multiplied 100 by 47, and then I removed one group of 47." Write an expression to represent how Susan solved 99x47. Then evaluate the expression.
Answers
Answer:
The expression of how Susan solved 99 × 47 is;
99 × 47 = 100 × 47 - 47
The evaluation of the expression is;
99 × 47 = 4653
Step-by-step explanation:
The question relates to the simplification of the multiplication of two numbers by the use of a combination multiplication of one of the numbers, 'x', with the nearest 10s or 100s of the other number, 'y', followed by the subtraction or addition operation of the product between the number 'x' and the difference between the specified 10s or 100s and 'y';
The given information on how Susan solved the equation 99 × 47 can be presented as follows;
99 × 47 = (100 - 1) × 47 = 100 × 47 - 47
The expression of how Susan solved 99 × 47 is therefore presented as follows;
99 × 47 = 100 × 47 - 47
The evaluation of the expression is therefore given as follows;
100 × 47 - 47 = 4700 - 47 = 4653.

Family spends $240 per week on food. If this is %16 of their income, what is the family's weekly income?
Answers
Answer: The family's weekly income is $1500
-------------------------------------------
Work Shown:
x = weekly income (in dollars)
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500
Pls Mark as brainliest
Answer:
1500
Step-by-step explanation:
16% of x = amount spent on food per week
16% of x = 240
(16/100)*x = 240
0.16*x = 240
0.16*x/0.16 = 240/0.16
x = 1500

-1 2/3 divided by (-2 1/5)
Answers
Answer:0.75757575757
Answer:
Fraction Form
25/33
Decimal Form
0.75
Step-by-step explanation:
First, convert the mixed fraction into an improper fraction, so it would look like:
-5/3 / (-11/5)
Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:
5/3 x 5/11
Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

Jake bought 3 drawing pens for $8.07. Each pen costs the same amount. About how much did he spend for one pen? * 2 points
Answers
Given:
Jake bought 3 drawing pens for $8.07.
Each pen costs the same amount.
To find:
How much did he spend for one pen?
Solution:
Let x be the cost of each pen. Then
Cost of three pens = 3x
Jake bought 3 drawing pens for $8.07.
[tex]3x=8.07[/tex]
Divide both sides by 3.
[tex]x=\dfrac{8.07}{3}[/tex]
[tex]x=2.69[/tex]
Therefore, he spend $2.69 for one pen.

Jane invests £1,200 in a bank account which
earns interest at the rate of 6% per annum.
Find the value of a) the investment after 5
years
Answers
Answer:
£1560
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year,
then, solving our equation
I = 1200 × 0.06 × 5 = 360
I = £ 360.00
The simple interest accumulated
on a principal of £ 1,200.00
at a rate of 6% per year
for 5 years is £ 360.00.
i= 1200 * 6 * 5/ 100
= 360

y = 10 and x = 8
Answers
Given:
y is proportional to x.
y=10 and x=8.
To find:
The constant of proportionality and the equation for the proportional relationship.
Solution:
y is proportional to x.
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting y=10 and x=8, we get
[tex]10=k(8)[/tex]
[tex]\dfrac{10}{8}=k[/tex]
[tex]\dfrac{5}{4}=k[/tex]
Putting [tex]k=\dfrac{5}{4}[/tex] in (i), we get
[tex]y=\dfrac{5}{4}x[/tex]
Therefore, the contestant of proportionality is [tex]k=\dfrac{5}{4}[/tex] and the equation for the proportional relationship is [tex]y=\dfrac{5}{4}x[/tex].
In 2019, the New England Patriots played 16 football games. The ratio of the number of games they won to the the number of games they lost was 3/1. How many games did they win? How many games did they lose?
Answers
Answer:
New England quarterback Tom Brady has the Patriots rolling again. ... In Week 2, they shut out the hapless Miami Dolphins, 43-0. ... Their start to 2019 has been so strong, even against opponents with a combined record ... and regress their win-loss records to account for the small number of games played.
Step-by-step explanation:
The number of games they won is 12 and the number of games they lost is 4 based on the given ratio.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Suppose the number of games they won is W and the number of games they lost is L.
As per the given
Total games L + W = 16
Ratio W/L = 3/1
W = 3L
L + 3L = 16
4L = 16
L = 4
And, W = 3 x 4 = 12
Hence"The number of games they won is 12 and the number of games they lost is 4 based on the given ratio".
