Answer:

Lydia's address is Cypress Street is: 51823

Step-by-step explanation:

Represent the digit as ABCDE such that:

A = Ones

B = Tens

C = Hundred

D = Thousand

E = Ten Thousand

Analyzing the statements one after the other:

The tens digit is 6 less than 7.

[tex]B = 7 - 6[/tex]

[tex]B = 1[/tex]

The thousands digit is twice the digit in the tens place.

[tex]D = 2B[/tex]

[tex]D = 2 * 1[/tex]

[tex]D = 2[/tex]

The hundreds digit is the greatest even number that is less than 10.

[tex]C = 8[/tex]

The ones digit is the product of 5 and 1.

[tex]A = 5 * 1[/tex]

[tex]A = 5[/tex]

The ten thousands digit is the difference between the hundreds digit and the ones digit.

[tex]E = C - A[/tex]

[tex]E = 8 - 5[/tex]

[tex]E = 3[/tex]

Lydia's address is Cypress Street is: 51823

Answer:

y = (-1/2)x + 4

Step-by-step explanation:

Slope (m): (-1/2)

down one, right two

y-intercept (b): 4

y = mx + b

The slope-intercept equation if the line is [tex]y=-\frac{1}{2}x+4[/tex]

To find the slope, you must put the 2 points into the slope equation.

[tex]\frac{3-4}{2-0}=\frac{-1}{2}[/tex]

And to find the y-intercept, you must find where the line crosses the y-axis.

Answer:

I believe it is 64 ( I might be wrong)

Step-by-step explanation:

ok so in the picture, the top of the rectangle has 8 square units so that means that the base also has 8 square units and if you look at the sides they also have 8 square unit so:

8 x 4 = 32

and then in the picture, the face of the rectangle has 16 square units so the other face also has 16 square units so:

16 x 2 = 32 plus the 32 from the sides in 64

hope that helps : )

Answer:C is the correct answer,

Step-by-step explanation:

50 ≤ s≤ 75 describes the number of sit-ups that Max does so option (B) will be correct.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

Max does "s" number of sit-ups then max brother will do "2s".

Now,

Given that,

Max's brother does between 100 and 150 sit-ups

So,

100 ≤ 2s ≤ 150

Divide by 2 into both sides

50 ≤ s ≤ 75

Hence " 50 ≤ s≤ 75 describes the number of sit-ups that Max does".

Answer:

y=13

Step-by-step explanation:

if x=20 when y=8 (we can creat equation )

x=2y+4 (you can prove that the equation is correct by substitute )

so the question is if x=30 find the value of y

30=2y+4

30‒4=2y

26=2y

26/2=2y/2

13=y

Answer:

5a + 2

Step-by-step explanation:

To find h(a + 1), substitute x = a + 1 into h(x), that is

h(a + 1) = 5(a + 1) - 3

            = 5a + 5 - 3

            = 5a + 2

Answer:

12 [tex]cm^2[/tex]

Step-by-step explanation:

The area of a triangle is [tex]\frac{bh}{2}[/tex]. Here, b = 8, h = 3. So 8*3/2 = 12. The units is [tex]cm^2[/tex].

So the answer is 12 [tex]cm^2[/tex].

Answer:

12 cm

Step-by-step explanation:

[tex] \frac{1}{2} \times 3 \times 8 = 12[/tex]

area = 1/2 base height

690,000

Step-by-step explanation:

The 8 is the ten thousands place- 685,135

If the number after the 8, (in this case 5) is 0-4, round to 8. If the number after the 8 is 5-9, round up to 9.

Answer:

Option (2)

Step-by-step explanation:

Steps to draw a perpendicular at a point lying on a segment;

1). Take a point on the segment at which the perpendicular is to be drawn.

2). Draw an arc from the point chosen on the segment which intersects the segment at the two different points.

3). Now mark two arcs from these points with the same radius intersecting each other on the same side of the segment.

4). Join the point of intersection of the arc with the point given on the line with straightedge.

Hence a perpendicular is drawn at a point of a segment.

These steps have been followed in option (2).

Option (2) will be the answer.

Answer:

S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2

Step-by-step explanation:

The given letters are;

SEND

MORE

MONEY

If we are to add the first two words to get the third word, then we have;

SEND + MORE = MONEY

Where, the letters are unique digits

The maximum value of M = 1, because, the two words are in thousands and their sum is in tens of thousands, they can make up to only a 10

Therefore, S = 9

O = 0

D + E = 10 + Y

1 + N + R = 10 + E

1 + E  = N

∴ 1 + N + R = 10 + E gives;

1 + 1 + E + R = 10 + E

R = 10 + E - (1 + 1 + E) = 8

R = 8

We have;

9 XXX + 108X = 10XXX

From 1 + N + R = 10 + E, we have;

1 + N + 8 = 10 + E

END + RE = NEY

E(1 + E)D + 8E = (1 + E)EY

(1 + E)EY - E(1 + E)D = 8E

10 + Y - D = E

By trial and error, we have;

If Y = 2 and D = 3, we have E = 9 which is not unique

Y = 4 and D = 3, we have E = 11 which is a double digit

Y = 2 and D = 7, we have E = 5

∴ N = 6 which is unique

Trying the combination gives;

S = 9, E = 5, N = 6, D = 7, M = 1, O = 0, R = 8, Y = 2

SEND + MORE = MONEY → 9567 + 1085 = 10652 which is correct.

Answer:

Step-by-step explanation:

2x + 3 = x/2 + 4

2x - x/2 = 4 - 3

3x/2 = 1

x = 1 (2) / 3

x = 2/3

substitute the value of x=2/3 back into the equation:

2(2/3) + 3 = (2/3)/2 + 4

4/3 + 3 = 1/3 + 4

Answer:

p = 1.2

Step-by-step explanation:

The given equation is :

–4.6p – 6.3p + 3.9 = –9.18

Combining the like terms,

–4.6p – 6.3p = -9.18 - 3.9

−10.9p = −13.08

⇒ [tex]p=\dfrac{-13.08}{-10.9}\\\\p=1.2[/tex]

Hence, the value of p is 1.2

Answer:

The  value  is [tex]E =19.6 [/tex]

Step-by-step explanation:

From the question we are told that

  The mean of Jo  cows is  [tex]\= x_1 = 1350[/tex]

  The standard deviation of Jo cow is  [tex]s_1 =  50[/tex]

  The mean of Val  cows is [tex]\= x_2  = 1420 [/tex]

   The standard deviation of Val  cows  is  [tex]s_2 =  50[/tex]

    The sample size for both Val  and  Jo  is  n = 25

Let assume that the level of significance is  [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

Hence margin of error for Jo is  

=>   [tex]E = 1.96 *  \frac{50}{\sqrt{25} }[/tex]

=>   [tex]E =19.6 [/tex]
