First, 4d-7=25/4
Then,4d=53/4.
Then you cross multiply, to get 16d = 53. Your final answer is 53/16, or 3 5/16.

First, let's solve the inequality
2.9 (x+8) < 26.1
2.9x + 23.2 <26.1
2.9x < 26.1 -23.2
2.9x <2.9
dividing both sides by 2.9 we get:
x < 1
so, it is the last numberline graph, because it contains an empty circle at 1 on the numberline, which means it doesn't include 1. but all numbers less than 1

Help please. I’m stuck on this one

Nastasia [14]

Answer:

b = 25m

Step-by-step explanation:

Hi there!

We're given angle B and the length of a in this right triangle. We must solve for the length of b. a and b are the two legs of the right triangle.

In this case, we can use the tangent ratio:

$tan\theta=\displaystyle\frac{opposite}{adjacent}$

Plug in the given information:

$tan\displaystyle\frac{\pi}{4} =\displaystyle\frac{b}{25}\\\\25tan\displaystyle\frac{\pi}{4} =b\\\\b=25$

Therefore, b = 25m.

We can also use this using special triangle rules. $\displaystyle\frac{\pi}{4}$ radians is equal to 45 degrees, making this a 45-90-45 triangle. This would make a and b equal in length.

I hope this helps!

Red roses come 3 to a package, and white roses come 5 to a package. If an equal number of red and white roses are wanted to make

Katen [24]

Answer:

B :- 15

Step-by-step explanation:

Given:

A package of red rose contains = 3 pieces

A package of white rose contains = 5 pieces

If an equal number of red and white roses are wanted to make bouquets, what is the minimum number of each that can be purchased ?

Solution:

As here given that there are two types of package of roses, red roses come 3 pieces to each packet and white roses come 5 pieces to each packet and we have to find equal minimum number of red roses as well as white roses to be purchased, we will simply find the Lowest common multiple of 3 and 5.

Multiples of 3 :- 3, 6, 9,12, 15, 18, 21, 24

Multiples of 5 :- 5, 10, 15, 20, 25

Lowest common multiple is 15, that means 15 is the minimum number of pieces of each that can be purchased to make bouquets.

And number of packets of red rose have to purchase = 3 $\times$ 5 = 15, 5 packages.

And number of packets of white rose have to purchase = 5 $\times$ 3 = 15 , 3 packages.
