Yesterday's low temperature was − 2 . 5 ∘ C −2.5 ∘ Cminus, 2, point, 5, degree, C. Today's low temperature is 5 55 times as low as yesterday's low temperature.

Answers

Answer 1

The temperature today would be -12.5 degrees.

If today's temperature is 5 times as low as yesterday's temperature, you just have to multiply it by 5.

-2.5 x 5 = -12.5

If the two rectangles are similar, their sides must be proportional. We can figure this out by setting up a proportion. We need to make sure to match up the correct sides though. We know the two longer sides must match up, so 6 goes with 60, and 3 goes with 30:

3/6=30/60

If we reduce the fractions, we get:

1/2=1/2

Therefore, the rectangles are similar. One of them is just rotated.

If 400 bricks measuring 81" by 31" are required to build a wall 42 ft. high, how long is the wall? feet.

Answers

let b bricks:

b= 400, let H height and l length

Area = 81*31 or 6.75*2.58 = 17.44 ft²

b(17.44ft²)=Hl

400(17.44 ft²) =42 l

l= 6975/42 = 166.07

so the length of the wall is 166 ft approximately as a whole number

Explain why the graph of quadratic function could not contain both a minimum vertex and maximum vertex at the same time.

Your explanation should be 3-4 sentences and include at least 6 of the following words.

-parabola
-U-shaped graph
-vertex
-minimum
-maximum
-Y-value of the vertex
-X-value of the vertex
-quadratic function

Answers

A parabola, a graph of a quadratic function, cannot have a maximum vertex and a minimum vertex at the same time because of the shape of the graph. A parabola is a u-shaped graph. The vertex of the parabola is the point where the u changes direction; if it was increasing, it starts to decrease, and if it was decreasing, it starts to increase. Since a parabola only changes direction once, there will either be a minimum or a maximum, not both.

I'm not sure how you got c but the way you would solve this is for every x on the line plot you would add that amount. You don't need to worry about 0 because 0 is nothing.
There are 3 X's at 1/4 so you would add 1/4+1/4+1/4=3/4. There are 2 X's at 1/2 so you would add 1/2+1/2=1. There are 2 X's at 3/4 so you would add 3/4+3/4=1.5. There is 1 X at 1 so it would just be 1. Then add all those together 3/4+1+1.5+1=4.25 or you could just add each X as you come across it on the number line like so:

what number should you subtract from the numerator of the fraction 52367/47633 and add to the denominator so that, after reducing, you get 17/38

Equation needed too!

Answers

The number you should subtract from the numerator (52367) and add to the denominator (47633) of the fraction 52367/47633 to obtain 17/38 after reducing is 21,458.

The equation is:

(52367 - 21458) / (47633 + 21458) = 17/38

To solve this problem, we need to find the number that, when subtracted from the numerator (52367) and added to the denominator (47633), will result in a fraction that reduces to 17/38.

Let's call this number x.

Step 1: Subtract x from the numerator and add x to the denominator.

(52367 - x) / (47633 + x)

Step 2: Set the resulting fraction equal to 17/38 and cross-multiply.

(52367 - x) / (47633 + x) = 17/38

(52367 - x) × 38 = 17 × (47633 + x)

Step 3: Solve for x.

1,990,946 - 38x = 810,761 + 17x

1,180,185 = 55x

x = 21,458

Therefore, the number you should subtract from the numerator (52367) and add to the denominator (47633) to obtain 17/38 after reducing is 21,458.

The equation representing this process is:

(52367 - 21458) / (47633 + 21458) = 17/38

Answers

What do you need?
The perimeter is L + w + L + perimeter of a semicircle.
L = 22 cm
W = 18 cm
Perimeter can be one of two answers. You need to specify where the semicircle is. Formula for semicircle is
pi * r
r = 18/2 = 9 or
r = 22/2 = 11
So the perimeter of the semi circle is pi * 9 = 25.12 The total Perimeter = 22 + 22 + 18 + 25.12 = 87.12

It can also be 22 + 18 + 22 + 34.54 = 96.54 There are even more possiblities for perimeter. I would have the same problem if you asked about area.

simplified form of the expression (5.23x + 3.76) − (3.67x − 6.39)

Answers

[tex]5.23x + 3.76 - 3.67x + 6.39 \\ = 1.56x + 10.15[/tex]

Answer:

1.56x + 10.15

Step-by-step explanation:

(5.23x + 3.76) – (3.67x – 6.39)

(a + b) – (c – d) = a + b – c + d

Remove the parentheses and change the signs as needed:

5.23x + 3.76 – 3.67x + 6.39.

Group the like terms and simplify:

5.23x – 3.67x + 3.76 + 6.39

1.56x +10.15.

The simplified form of (5.23x + 3.76) – (3.67x – 6.39) is 1.56x + 10.15.

The measure of angle x is 25 more than 4 times the measure of its complement. Find the measure of x.

Answers

- Two angles that are complements of each other add to equal 90 degrees (they are complementary angles).
- One angle measures x degrees.
- The other angle measures 25 more than 4 times the angle that measures x degrees; it measures 4x + 25 degrees.

To find x, set the sum of these expressions (x and 4x + 25) equal to 90 and solve algebraically for x.

90 = x + (4x + 25)
90 = x + 4x + 25
90 = 5x + 25
65 = 5x
13 = x

If you wanted to find the measure of angle x, you'd substitute 13 for x in its expression, 4x + 25.

Answers

tricycle has 3 wheels and 2 pedals

EQ 1 : 2b + 2t = 170 pedals

EQ 2: 2b +3t = 206 wheels

subtract EQ 1 from EQ 2

2b +3t = 206 - 2b + 2t = 170 = t=36

there were 36 tricycles

36 x 2 = 72 pedals

170 pedals - 72 = 98 pedals left
98/2 = 49 bicycles

36 Tricycles and 49 bicycles

The height of a model rocket is 4.5% of the height of the actual rocket. The model is 1.32m high. How high is the actual rocket? Please show your work.

Answers

1.32 meters = 4.5%x

x is the actual height of the rocket.

4.5% is really 0.045 (move the decimal place 2 times to the left).

1.32 = 0.045x
Divide both sides by 0.045.

x = 29.3

The height of the actual rocket is 29.3 meters.

To find the height of the actual rocket given the height of the model rocket, we can use the ratio between the two. By setting up and solving a simple equation, we can determine that the height of the actual rocket is 29.33 meters.

To find the height of the actual rocket, we need to start by determining the ratio between the height of the model rocket and the actual rocket. Given that the model rocket is 4.5% of the height of the actual rocket, we can use this ratio to solve for the height of the actual rocket.

Let's denote the height of the actual rocket as x. Since the model rocket is 4.5% (or 0.045) of the actual rocket's height, we can set up the equation:

0.045x = 1.32

To solve for x, we divide both sides of the equation by 0.045:

x = 1.32 / 0.045

Calculating this expression gives us the height of the actual rocket as 29.33 meters.

Kristen has 64 coins in her bank. She has $9.25 in dimes and quarters. How many dimes and quarters does she have?

Answers

d= # of dimes
q= # of quarters

QUANTITY EQUATION:
d + q= 64

COST EQUATION:
0.10d + 0.25q= $9.25

STEP 1:
multiply quantity equation by -0.10 to be able to eliminate the d term in step 2

(-0.10)(d + q)= (-0.10)(64)
-0.10d - 0.10q= -6.40

STEP 2:
add equation from step 1 to cost equation to eliminate the d term and solve for q

Add
0.10d + 0.25q= $9.25
-0.10d - 0.10q= -6.40

0.15q= 2.85
divide both sides by 0.15

q= 19 quarters

STEP 3:
substitute q value in step 2 into either original equation to find d value

d + q= 64

d + 19= 64
subtract 19 from both sides

d= 45 dimes

CHECK:
0.10d + 0.25q= $9.25
0.10(45) + 0.25(19)= 9.25
