3. Jennie and Ada are playing a card game where they score points. After one round the ratio of Jennie's points
to Ada's points is 4 to 7. If Ada has 15 more points than Jennie, how many points does Jennie have?
Jennie has 20 points.
Explanation:
to Ada's points is 4 to 7. If Ada has 15 more points than Jennie, how many points does Jennie have?
To solve this problem, we can use proportions. We know that the ratio of Jennie's points to Ada's points is 4 to 7, so we can set up the following proportion:
4/7 = Jennie's points / Ada's points
We also know that Ada has 15 more points than Jennie, so we can add 15 to both sides of the proportion to represent this:
4/7 = Jennie's points / (Jennie's points + 15)
Next, we can cross-multiply to solve for Jennie's points:
4 * (Jennie's points + 15) = 7 * Jennie's points
4 * Jennie's points + 60 = 7 * Jennie's points
We can then subtract 4 * Jennie's points from both sides to isolate the variable:
60 = 3 * Jennie's points
Finally, we can divide both sides by 3 to find the value of Jennie's points:
Jennie's points = 60/3 = 20
Thus, Jennie has 20 points.

What is the value of K if the expression (- 5x3 + 4x2 – 3x + K) is divided by (x-1), and obtains a remainder of 10?
Answer:
14
Step-by-step explanation:
To find the value of K, we need to use the remainder theorem. The remainder theorem states that if a polynomial is divided by (x - a), where a is a number, the remainder of the division will be equal to the value of the polynomial when x is equal to a. In this case, the remainder of the division is 10, so we need to find the value of the polynomial when x is equal to 1.
To find this value, we need to plug 1 into the original polynomial and evaluate it. This gives us (- 5 * 1^3 + 4 * 1^2 – 3 * 1 + K) = (- 5 + 4 – 3 + K) = (- 4 + K). Since the remainder of the division is 10, we know that (- 4 + K) = 10. This means that K = 14.
Therefore, the value of K in the original polynomial is 14.
The value of K is 14.
What is Remainder Theorem?If a polynomial function f(x) is divided by (x - c), the remainder R is given by: R = f(c)
According to the remainder theorem, if a polynomial f(x) is divided by (x - c), where c is a constant, the remainder is equal to f(c).
In this case, we know that the remainder is 10 when the expression is divided by (x - 1). So, we can substitute x = 1 into the expression and set it equal to 10 to find the value of K.
Substituting x = 1 into the expression, we get:
(-5 (1)³ + 4(1)² - 3(1) + k)= 0
-5 + 4 -3 + k = 0
k -4 = 0
k = 4
Therefore, the value of K is 14.

The diameter of a penny is 19 mm. How far from your eye must it be held so that it has the same apparent size as the moon?
For a penny of diameter 19mm to be of the same apparent size as the moon it should be held at a distance of about 2.1m away from the eye.
Therefore, the answer is 2.1m.
Distance of moon from earth is 384,400km, that is 384,400,000m. Also 3,474.8km that is 3,474,800m.
For penny to have same apparent size as the moon, it should subtend equal angle as moon to the viewer. See the attached figure for reference. Thus ΔABC is similar to ΔEDB by AA criterion as ∠A is common and ∠BAC = ∠DEB as they are corresponding angles.
Let distance between penny and observer be x. Then
x/ ED = 384,400,000m/ AB
x/ 19mm = 384,400,000m/ 3,474,800m
x/ 19mm = 961000/ 8687

What are congruent triangles?Two triangles are congruent if two angles and a non included side of one triangle are congruent to two angles and a non included side of another triangle.
The relationship between the triangles ΔAOI and ΔIEA is ΔAOI ≅ ΔIEA
Therefore; ∠IEA is congruent to ∠AOI, by Corresponding Parts of Congruent Triangles are Congruent, CPCTC
∠IEA ≅ ∠AOI
Therefore; ∠IEA = ∠AOI by the definition of congruency
(6·z + 8)° = (7·z - 12)°
7·z - 6·z = (8 + 12)° = 20°
z = 20°
∠AOI = (7·z - 12)°
Therefore;
∠AOI = (7 × 20 - 12)° = 128°
∠IEA = 128°
Similarly; AO ≅ EI by CPCTC
AO = EI definition of congruency
5·w - 6 = 2·w
5·w - 2·w = 6
3·w = 6
w = 6 ÷ 3 = 2
w = 2
∠OIA ≅ ∠EAI by CPCTC
Therefore; ∠OIA = ∠EAI definition of congruency
(7·x + 17)° = 3·(4·x - 1)° substitution property
(7·x + 17)° = 3·(4·x - 1)° = (12·x - 3)°
12·x - 7·x = 17° + 3° = 20°
5·x = 20°
x = 20° ÷ 5 = 4°
x = 4°
∠EAI = 3·(4·x - 1)°
∠OIA = (7·x + 17)°
Therefore;
∠EAI = 3·(4×4 - 1)° = 45°
∠OIA = (7×4 + 17)° = 45°
y° + (7·z - 12)° + 3·(4·x - 1)° = 180° (angle sum property of a triangle)
∠AOI = (7·z - 12)° = 128°
∠EAI = 3·(4·x - 1)° = 45°
Therefore;
y° + 128° + 45° = 180°
y° = 180° - (128° + 45°) = 7°

How to find the quotient?A quotient is a quantity produced by the division of two numbers in arithmetic. The quotient is widely used in mathematics and is also known as the integer part of a division, a fraction, or a ratio.
The quotient is the result of performing division operations on two numbers. It is essentially the result of the division method. In arithmetic division, four main terms are used: divisor, dividend, quotient, and remainder
In this case, we want to divide 3 and 1/5. This will be:
= 3 ÷ 1/5
= 3 × 5
= 15.
The quotient is 15.

Step-by-step explanation:
one segment measures 161 cm. Calculate its multiple according to the number 3 and its submultiple according to the number 7
By using multiplication and division, it can be calculated that-
The multiple according to the number 3 = 162
The submultiple according to the number 7 = 7
What is multiplication and division?
Repeated addition is called multiplication. Multiplication is used to find the product of two or more numbers.
Division is the process in which a value of single unit can be calculated from the value of multiple unit.
The number to be divided is called dividend. The number by which dividend is divided is the divisor. The result obtained is called quotient and the remaining part is the remainder.
This is a problem of multiplication and division.
One segment measures 161 cm
So, to find the multiple according to the number 3, we have to divide 161 by 3
161 [tex]\div[/tex] 3 = 53.67
Nearest integer of 53.67 is 54
The multiple according to the number 3 = 54 [tex]\times[/tex] 3 = 162
To find the submultiple according to the number 7, we have to divide 161 by 7
161 [tex]\div[/tex] 7 = 23
Nearest integer of 23 is 23
The submultiple according to the number 7 = 161 [tex]\div[/tex] 23 = 7
