Bruno‘s mother is eight more than twice his age. His father is three years older than his mother is. If all three members have lived a total of 94 years, how old is each family member?

Answers

Answer 1

Answer:

Bruno = 15 years

Mother = 8 + 2(15) = 38 years

Father = 38 + 3 = 41 years

Step-by-step explanation:

Given that :

Let

Bruno's age = x

Mothers age = 8 + 2x

Father's age = 8 + 2x + 3 = 2x + 11

x + 8 + 2x + 2x + 11 = 94

5x + 19 = 94

5x = 75

x = 75 /5

x = 15

Bruno = 15 years

Mother = 8 + 2(15) = 38 years

Father = 38 + 3 = 41 years

The figure is a parabola

Step-by-step explanation:

standard form. Ax+By=C. what is c, how do i find the slope, how do i find the x intercept, how do i find the y intercept. can you please give a simple example?

Answers

c represents the y-intercept (the “b” in slope intercept form) to find the slope, you simply change it to slope intercept form ( move the Ax to the other side of the equation and divide by B *whatever number is attached to the y that you need to get rid of to get y alone*) to find the x intercept, you replace y with a zero (this is because you don’t want to find y so you are taking it away from the equation so you are left with Ax=c) and you divide A by c to get x alone (bc a is attached to the x so you divide to get rid of it) and the same process for y-intercept. except you are placing the zero in the x rather than the y.

sample example:
2x+6y=12
finding the slope:
6y=-2x+12
(divide by 6)
y=-2/6+2
slope= -2/6

y intercept:
2x+6y=12
2(0)+6y=12
6y=12
(divide by 6)
y=2

x-intercept

2x+6y=12
2x+6(0)=12
2x=12
(divide by 2)
x=6

The corner market sells potatoes at a rate of 1/2 dollars per potato.
1. Amanda is only able to spend $5 on potatoes. What is the most number of potatoes she can buy?
2. Sam wants to buy 15 potatoes. How much will that cost him?

Answers

Answer:

The cost of 15 potatoes is $7.50

Step-by-step explanation:

The potatoes are sold at a rate of $0.5 per potato.

1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.

Amanda can buy at most 10 potatoes

2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:

15 * $0.5 = $7.50

The cost of 15 potatoes is $7.50

i need answer today . Jill made the model below to show the quotient

.

An image shows three groups of three tenths and two hundredths.

Which of the following explains the mistake Jill made?

A.

Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.

B.

Jill used groups of 3 tenths and 2 hundredths rather than groups of 4 tenths.

C.

Jill used 3 groups of 3 tenths and 2 hundredths rather than 2 groups.

D.

Jill used groups of 3 tenths and 2 hundredths rather than groups of 3 tenths and 8 hundredths.

Answers

Answer:

Step-by-step explanation: By looking at the image it shows 2 not 4.

The only option that explains the mistake Jill made in the model is;

Option A; Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.

The model Jill made is to show the quotient of 1.28 ÷ 4.

Now, this means she wants to divide 1.28 into 4 equal parts. Thus, the model must show 4 identical quotients.

The image of the model we are seeing from Jill is showing;

3 groups of 3 tenths and 2 hundredths.

Since it is showing 3 groups instead of 4 groups, the it is clear that Jill made a mistake in her model.

In conclusion, the only option that identifies the mistake correctly is option A.

The correct option is;

26.8

Step-by-step explanation:

The given parameters are;

The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS

Therefore;

in Segment MN, segment QM = segment QN, by definition of bisected line

Segment OQ = Segment OQ by reflexive property

∠OQM = ∠OQN = 90° by definition of perpendicular bisector

∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency

Two angels of a triangle measure 12 and 40.
What is the measure of the third angle of the triangle ?

C) 128

Step-by-step explanation:

Sum of all three angles of triangle = 180

Let the third angle be 'x'

x + 12 + 40 = 180

x + 52 = 180

x = 180 - 52

x = 128

Answer:

a) Center of dilation (0,0)

b) Scale factor = 2

Step-by-step explanation:

Dilation of Polygons

The triangle ABC has its vertices at A(-2,2), B(4,2), and C(-2,-2).

The triangle A'B'C' has its vertices at A'(-4,4), B'(8,4), and C'(-4,-4).

Since A'B'C' is a dilation of ABC, we check if all its vertices are proportional with the same scaling factor.

Both vertices of A' are twice the vertices of A: (-4,4)=2*(-2,2)

Both vertices of B' are twice the vertices of B: (8,4)=2*(4,2)

Both vertices of C' are twice the vertices of C: (-4,.4)=2*(-2,-2)

The proportionality of the coordinates of the vertices tells us the center of dilation must be the origin of coordinates (0,0).

The scale factor is the constant number all the vertices are multiplied by, that is, scale factor = 2
