Answer:

  7 dimes

Step-by-step explanation:

Let d represent the number of dimes. Then 23-d is the number of quarters, and the total value is ...

  0.10d + 0.25(23-d) = 4.70

  -0.15d +5.75 = 4.70 . . . . . simplify

  1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides

  7 = d . . . . . . . . . . . divide by 0.15

There were 7 dimes in the change purse.

area=(4×9)÷2=18 inch²

The diagonals of a kite have lengths of 4 inches and 9 inches. Find the area of the kite. The area is 18 square inches

To find the area of a kite, we can use the formula:

Area = (diagonal 1 * diagonal 2) / 2

The area of a shape can be calculated using different formulas depending on the type of shape. For basic geometric shapes, such as squares, rectangles, triangles, and circles, there are specific formulas that relate the dimensions of the shape to its area.

For irregular shapes, the area can be determined by breaking the shape into smaller, more manageable components and summing their individual areas.

In this case, the diagonals of the kite have lengths of 4 inches and 9 inches. Plugging these values into the formula, we get:

Area = (4 * 9) / 2

Area = 36 / 2

Area = 18 square inches

Therefore, the area of the kite is 18 square inches.

[61.5, 62.5]

Step-by-step explanation:

The Empirical Rule states that 68% of data observed following a normal distribution lies within 1 standard deviation of the mean.

Thus, you can see that one standard deviation away on both sides land on 61.5 and 62.5

That interval represents 68% of her finishing times in the 400m race.

Victoria need to invest, to the nearest [tex]421[/tex] dollar, for the value of the account to reach [tex]$580[/tex] in [tex]6[/tex] years.

Learn more about probability here,

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

It is given that the interest rate is [tex]\[6.6%\][/tex] %, and year is [tex]6[/tex] and the value of the account to reach is [tex]$580\$$[/tex].

We will solve this problem by using the following compound interest formula or Single payment compound amount formula,

[tex]$F=P{{(1+i)}^{n}}$[/tex]

Where, [tex]i[/tex] is the interest rate per compound period, [tex]n[/tex] is the number of [tex]i[/tex]compounding period, [tex]P[/tex] is preset sum of money and [tex]F[/tex] is a future sum of money.

So,

[tex]$P=\frac{F}{{{\left( 1+i \right)}^{n}}}$[/tex]

[tex]$P=\frac{580}{{{\left( 1+6.6 \right)}^{6}}}$[/tex]

[tex]$P\approx 421$[/tex]

Hence, The Victoria needs to invest approximate [tex]$421\$$[/tex].

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

Answer:

The y-intercept is 16

Step-by-step explanation:

Here , we want to find the y-intercept

generally, we have the equation of the line as

y = mx + b

where b is the y-intercept and m is the slope

From what we have;

y = 2x + b

To get the slope, we substitute the coordinates of the points (-6,4)

we have this as:

4 = 2(-6) + b

4 = b - 12

b = 4 + 12

b = 16

Answer:

z=15/4

Step-by-step explanation:

First you want to take z and multiple it by both sides:

6/ZxZ=8/6xZ

6=8z/6

Now you want to do the same thing with 5:

6x5=8z/5x5

30=8z

Now finally you divide both sides by 8 to get z alone:

30÷8=8z÷8

3.75=z

3.75=15/4

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.

Answer:

-4

Step-by-step explanation:

To find the x-coordinate of the vertex of a parabola given its x-intercepts, find the average of the x-intercepts:

x-coordinate of the vertex = [tex]\frac{x_1+x_2}{2}[/tex] (where [tex]x_1[/tex] and [tex]x_2[/tex] are the x-intercepts)

Plug in the x-intercepts 13 and -21

[tex]\frac{13+(-21)}{2}\\= \frac{13-21}{2}\\= \frac{-8}{2}\\=-4[/tex]

Therefore, the x-coordinate of the vertex is -4.

ither b or d  would say d

Answer:

Both answers are "B" im pretty sure.

Step-by-step explanation:

hope this helps! :)

Answer:

The answer is C

Well lets calculate the slope = the slope which can clearly be seen which is 2x because each time it goes up it goes one to the right so it is 2x

y intercept = where is the y intercept, well clearly seen the y intercept is at 1

so when converted to y=mx+b it is y=2x+1

so slope = 2 and y intercept = 1

HOPE IT HELPS :)

Answer:

I think it is C because The line is positive so the slope should be positive so 2 and the y intercept is 1 since it is showing in the y axis. so C

Answer:

d= 90 degrees

e= 99 degrees

f= 81 degrees

Step-by-step explanation:

To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees

If this answer has helped you, please mark this answer as brainliest

Answer:

D = 90° | E = 99° | F = 81°

Step-by-step explanation:

99 degrees and E are the same.

D is a right angle, so 90°.

F is below 99°, so you subtract 99° from 180° to get 81°.

D = 90°

E = 99°

F = 99°

I did 0.80-0.25=0.55

so I figured that is what she had left so I know took the total 0.80-0.55 and got0.25 which is B.

My friend said the correct answer was A.

Don't worry I just did this problem!

The distance Josh ran more in June than in July, if Josh ran 84.6 miles in June. In July, he ran 0.55 times this distance in June, is 38.07 miles.

The complete movement of an object, regardless of direction, is referred to as distance. The amount of ground a thing travels from its starting point to its destination is also referred to as distance.

Given:

Josh ran 84.6 miles in June. In July, he ran 0.55 times this distance in June,

Calculate the distance covered in July = 0.55 × 84.6

Calculate the distance covered in July = 46.53 miles

Calculate the distance he ran more in June than in July = 84.6 - 46.53

The distance he ran more in June than in July = 38.07 miles
